Astro-Physics 10 Inch (25.4cm) f14.6 Maksutov-Cassegrain High Resolution Telescope

Astro-Physics Co. who are known for making the world's most advanced, versatile, and desired lines of Apochromatic refractor telescopes began the year 2000 with the announcement of their first production Catadioptric telescope!

After more than a decade of research and development to "get it right" Astro-Physics has sold out the first of a limited number of Maksutov"Mak" telescopes. Designated the Astro-Physics 10 inch f14.6 Maksutov Apochromat telescope, this is a compact 33 lb. (15 kg) high resolution instrument designed to provide refractor like views (and images) of the brighter, small objects including the planets, moon, double stars, and the like.Astro-Physics has been working to make a telescope that would be more compact, perform well in temperature extremes around the world, and meet their exacting requirements for optical and mechanical excellence: they have continued their tradition of innovative excellence.

A further goal in this development effort was to equal or to approach the performance of their highly prized triplet apochromatic refractors in at least certain applications. One thought in producing these Catadioptric telescopes is that if a number of customers who do not require the versatility of the Apo refractors (which perform superbly well at extremely high magnifications, and down to very low magnifications) will order the Mak telescopes instead of the triplet Apos then this may take some of the burden from the Triplet production line, and thereby helpAstro-Physics to satisfy a far greater number of the more demanding amateur and professional clientele.

Deliveries from the first production run will commence in limited numbers in April of year 2000. It is likely that production will accelerate, and the 10 inch model is likely to be followed by other variants of the design in terms of designed function and aperture.

The primary mirror is a truncated cone designed to eliminate as much thermal mass as possible. The rear surface of the mirror is fine ground and then polished, a process which also helps internal trapped heat to radiate out the open back. By grinding the edge and back of this mirror, any tiny stresses are relieved which could otherwise introduce unwanted distortions in the highly accurate front surface at varying ambient temperatures. In side-by-side tests against closed back scopes with conventional molded mirrors, theAstro-Physics design was faster, by far, in achieving a stable and accurate image.

Any optical imperfections such as a degree of surface roughness and zonal errors on the optical surface will compound the problem.Astro-Physics tested a commercial telescope where the central obstruction, optical errors and surface roughness were large enough to cause the first diffraction ring and central Airy disc to have almost equal brightness (with a 35% obstruction, theoretically there should be at least a4 to 1 difference). Even so, this sample telescope "tested" very well on the star test - it had quite similar inside and outside Fresnel patterns and might be judged to be textbook perfect by the star test. Yet it was a very poor performer on all but the most steady of nights, when the seeing was essentially perfect. The slightest motion in the atmosphere would result in a display of "cotton ball" stars. This is one reason whyAstro-Physics and Company Seven have not been a major fans of the "star test" to evaluate the actual performance of a telescope. The only unbiased way to measure an optic is withinterferometry, or by an MTF (modulation transfer function) test, or with a PSF (point spread function) test, which measures the relative strength of the Airy disc versus the diffraction rings with the image in focus.

Astro-Physics has endeavored to achieve the highest absorption of stray light possible by employing state of the art baffling and anti-reflection techniques; this will help to provide the user with maximum contrast. The exterior of the telescope is finished in a durable textured off white finish, with black anodized focuser and cells; these will retain their beauty for many years. You will appreciate the unique design and fine craftsmanship of this telescope.

Knife edge baffles are machined into the walls of the telescope optical tube and of the focuser draw tube, these and painted flat black in order to maximize contrast by essentially eliminating any internal reflections. The inside diameter (I.D.) of the draw tube permits the avid astrophotographer to employ up to a 35mm format film or CCD camera to capture images. You can use standard 2 inch diameter accessories, and with the furnished 1.25 inch adapter (threaded for 48mm filters) use common oculars and accessories too. Recessed brass locking rings are installed at each thumbscrew location; as you tighten a thumbscrew a brass locking ring clamps onto the part that has been inserted; consequently the focuser draw tube and any accessories are held securely in place and will not mar the surface of your accessories. This is particularly important considering the heavy and expensive accessories that you may use.

* Specifications are subject to change without notice.

Your local seeing conditions will greatly affect whether or not you may operate the telescope at its highest magnifications. Please call to discuss this if you have any questions.

Vox Popoli: What the Alternative Right is

In the interest of developing a core Alternative Right philosophy upon which others can build.

The patron saint of conservatives, Russell Kirk, wrote: "The great line of demarcation in modern politics, Eric Voegelin used to point out, is not a division between liberals on one side and totalitarians on the other. No, on one side of that line are all those men and women who fancy that the temporal order is the only order, and that material needs are their only needs, and that they may do as they like with the human patrimony. On the other side of that line are all those people who recognize an enduring moral order in the universe, a constant human nature, and high duties toward the order spiritual and the order temporal."

This is no longer true, assuming it ever was. The great line of demarcation in modern politics is now a division between men and women who believe that they are ultimately defined by their momentary opinions and those who believe they are ultimately defined by their genetic heritage. The Alt Right understands that the former will always lose to the latter in the end, because the former is subject to change.

Protesters Try to Shut Down Jordan Peterson at Queen’s …

I honestly dont get the outrage over Jordan Peterson. Its the equivalent of getting upset over Kermit the Frog. Singing about 12 rules for life. While playing a banjo. But if theres two places where free speech is triggering, its college campuses and Canada (seeAltLeft Shuts Down Toronto Comedy Show Over Words Free SpeechandWATCH: University Protestors Scream, Sing, and Blare a Speaker Over Christina Sommers). The professor shared a few videos from his recent speech at Queens University.

These students seem like theyre fun at parties. Their rhymes are wack though. FYI, these students are textbook examples of Social Justice Warriors which we shorten to SJWs. Because Fecal-flinging Monkey Trolls is too long to type.

Not everyone was able to get inside. Some surrounded the building and started banging on the window. No word yet on if they flung their poo. But we do have footage of these SJWs picking fleas off each other. Eating the fleas for a little protest nourishment.

Eventually, the perimeter was breached. The SJWs stormed the stage. Now was there chance to be heard. So much limb swinging to be had.

And this was the best they could come up with.

Heres what I love best. Jordan Peterson recently told Joe Roganhes managed to monetize SJW outrage. The more they complain, the more paper he gets. So sure, he was frustrated while this was going on. But in his head, hes thinking:

You would think after decades of student protests, theyd realize their adversaries are much smarter in all ways. Including how to earn fat stacks off their stupid. As much as SJWs try to shut down opposing viewpoints, the opposing viewpoints just grow stronger. The perpetrators of those opposing viewpoints make more money. While the students protesting just look stupid.

STUDENT #1: Man, f*** Jordan Peterson.

STUDENT #2: You realize the more we complain, the more donations he gets through Patreon, right.

STUDENT #1: IT IS RIGHT TO REBEL! YOUR LOGIC CAN GO TO HELL.

God bless college, and the zookeepers who let the apes run free to pee.

How does Ethereum work, anyway? – Medium

Introduction

Odds are youve heard about the Ethereum blockchain, whether or not you know what it is. Its been in the news a lot lately, including the cover of some major magazines, but reading those articles can be like gibberish if you dont have a foundation for what exactly Ethereum is. So what is it? In essence, a public database that keeps a permanent record of digital transactions. Importantly, this database doesnt require any central authority to maintain and secure it. Instead it operates as a trustless transactional systema framework in which individuals can make peer-to-peer transactions without needing to trust a third party OR one another.

Still confused? Thats where this post comes in. My aim is to explain how Ethereum functions at a technical level, without complex math or scary-looking formulas. Even if youre not a programmer, I hope youll walk away with at least better grasp of the tech. If some parts are too technical and difficult to grok, thats totally fine! Theres really no need to understand every little detail. I recommend just focusing on understanding things at a broad level.Many of the topics covered in this post are a breakdown of the concepts discussed in the yellow paper. Ive added my own explanations and diagrams to make understanding Ethereum easier. Those brave enough to take on the technical challenge can also read the Ethereum yellow paper.

Lets get started!

A blockchain is a cryptographically secure transactional singleton machine with shared-state. [1] Thats a mouthful, isnt it? Lets break it down.

Ethereum implements this blockchain paradigm.

The Ethereum blockchain is essentially a transaction-based state machine. In computer science, a state machine refers to something that will read a series of inputs and, based on those inputs, will transition to a new state.

With Ethereums state machine, we begin with a genesis state. This is analogous to a blank slate, before any transactions have happened on the network. When transactions are executed, this genesis state transitions into some final state. At any point in time, this final state represents the current state of Ethereum.

The state of Ethereum has millions of transactions. These transactions are grouped into blocks. A block contains a series of transactions, and each block is chained together with its previous block.

To cause a transition from one state to the next, a transaction must be valid. For a transaction to be considered valid, it must go through a validation process known as mining. Mining is when a group of nodes (i.e. computers) expend their compute resources to create a block of valid transactions.

Any node on the network that declares itself as a miner can attempt to create and validate a block. Lots of miners from around the world try to create and validate blocks at the same time. Each miner provides a mathematical proof when submitting a block to the blockchain, and this proof acts as a guarantee: if the proof exists, the block must be valid.

For a block to be added to the main blockchain, the miner must prove it faster than any other competitor miner. The process of validating each block by having a miner provide a mathematical proof is known as a proof of work.

A miner who validates a new block is rewarded with a certain amount of value for doing this work. What is that value? The Ethereum blockchain uses an intrinsic digital token called Ether. Every time a miner proves a block, new Ether tokens are generated and awarded.

You might wonder: what guarantees that everyone sticks to one chain of blocks? How can we be sure that there doesnt exist a subset of miners who will decide to create their own chain of blocks?

Earlier, we defined a blockchain as a transactional singleton machine with shared-state. Using this definition, we can understand the correct current state is a single global truth, which everyone must accept. Having multiple states (or chains) would ruin the whole system, because it would be impossible to agree on which state was the correct one. If the chains were to diverge, you might own 10 coins on one chain, 20 on another, and 40 on another. In this scenario, there would be no way to determine which chain was the most valid.

Whenever multiple paths are generated, a fork occurs. We typically want to avoid forks, because they disrupt the system and force people to choose which chain they believe in.

To determine which path is most valid and prevent multiple chains, Ethereum uses a mechanism called the GHOST protocol.

GHOST = Greedy Heaviest Observed Subtree

In simple terms, the GHOST protocol says we must pick the path that has had the most computation done upon it. One way to determine that path is to use the block number of the most recent block (the leaf block), which represents the total number of blocks in the current path (not counting the genesis block). The higher the block number, the longer the path and the greater the mining effort that must have gone into arriving at the leaf. Using this reasoning allows us to agree on the canonical version of the current state.

Now that youve gotten the 10,000-foot overview of what a blockchain is, lets dive deeper into the main components that the Ethereum system is comprised of:

One note before getting started: whenever I say hash of X, I am referring to the KECCAK-256 hash, which Ethereum uses.

The global shared-state of Ethereum is comprised of many small objects (accounts) that are able to interact with one another through a message-passing framework. Each account has a state associated with it and a 20-byte address. An address in Ethereum is a 160-bit identifier that is used to identify any account.

There are two types of accounts:

Its important to understand a fundamental difference between externally owned accounts and contract accounts. An externally owned account can send messages to other externally owned accounts OR to other contract accounts by creating and signing a transaction using its private key. A message between two externally owned accounts is simply a value transfer. But a message from an externally owned account to a contract account activates the contract accounts code, allowing it to perform various actions (e.g. transfer tokens, write to internal storage, mint new tokens, perform some calculation, create new contracts, etc.).

Unlike externally owned accounts, contract accounts cant initiate new transactions on their own. Instead, contract accounts can only fire transactions in response to other transactions they have received (from an externally owned account or from another contract account). Well learn more about contract-to-contract calls in the Transactions and Messages section.

Therefore, any action that occurs on the Ethereum blockchain is always set in motion by transactions fired from externally controlled accounts.

The account state consists of four components, which are present regardless of the type of account:

Okay, so we know that Ethereums global state consists of a mapping between account addresses and the account states. This mapping is stored in a data structure known as a Merkle Patricia tree.

A Merkle tree (or also referred as Merkle trie) is a type of binary tree composed of a set of nodes with:

The data at the bottom of the tree is generated by splitting the data that we want to store into chunks, then splitting the chunks into buckets, and then taking the hash of each bucket and repeating the same process until the total number of hashes remaining becomes only one: the root hash.

This tree is required to have a key for every value stored inside it. Beginning from the root node of the tree, the key should tell you which child node to follow to get to the corresponding value, which is stored in the leaf nodes. In Ethereums case, the key/value mapping for the state tree is between addresses and their associated accounts, including the balance, nonce, codeHash, and storageRoot for each account (where the storageRoot is itself a tree).

This same trie structure is used also to store transactions and receipts. More specifically, every block has a header which stores the hash of the root node of three different Merkle trie structures, including:

The ability to store all this information efficiently in Merkle tries is incredibly useful in Ethereum for what we call light clients or light nodes. Remember that a blockchain is maintained by a bunch of nodes. Broadly speaking, there are two types of nodes: full nodes and light nodes.

A full archive node synchronizes the blockchain by downloading the full chain, from the genesis block to the current head block, executing all of the transactions contained within. Typically, miners store the full archive node, because they are required to do so for the mining process. It is also possible to download a full node without executing every transaction. Regardless, any full node contains the entire chain.

But unless a node needs to execute every transaction or easily query historical data, theres really no need to store the entire chain. This is where the concept of a light node comes in. Instead of downloading and storing the full chain and executing all of the transactions, light nodes download only the chain of headers, from the genesis block to the current head, without executing any transactions or retrieving any associated state. Because light nodes have access to block headers, which contain hashes of three tries, they can still easily generate and receive verifiable answers about transactions, events, balances, etc.

The reason this works is because hashes in the Merkle tree propagate upwardif a malicious user attempts to swap a fake transaction into the bottom of a Merkle tree, this change will cause a change in the hash of the node above, which will change the hash of the node above that, and so on, until it eventually changes the root of the tree.

Any node that wants to verify a piece of data can use something called a Merkle proof to do so. A Merkle proof consists of:

Anyone reading the proof can verify that the hashing for that branch is consistent all the way up the tree, and therefore that the given chunk is actually at that position in the tree.

In summary, the benefit of using a Merkle Patricia tree is that the root node of this structure is cryptographically dependent on the data stored in the tree, and so the hash of the root node can be used as a secure identity for this data. Since the block header includes the root hash of the state, transactions, and receipts trees, any node can validate a small part of state of Ethereum without needing to store the entire state, which can be potentially unbounded in size.

One very important concept in Ethereum is the concept of fees. Every computation that occurs as a result of a transaction on the Ethereum network incurs a feetheres no free lunch! This fee is paid in a denomination called gas.

Gas is the unit used to measure the fees required for a particular computation. Gas price is the amount of Ether you are willing to spend on every unit of gas, and is measured in gwei. Wei is the smallest unit of Ether, where 1 Wei represents 1 Ether. One gwei is 1,000,000,000 Wei.

With every transaction, a sender sets a gas limit and gas price. The product of gas price and gas limit represents the maximum amount of Wei that the sender is willing to pay for executing a transaction.

For example, lets say the sender sets the gas limit to 50,000 and a gas price to 20 gwei. This implies that the sender is willing to spend at most 50,000 x 20 gwei = 1,000,000,000,000,000 Wei = 0.001 Ether to execute that transaction.

Remember that the gas limit represents the maximum gas the sender is willing to spend money on. If they have enough Ether in their account balance to cover this maximum, theyre good to go. The sender is refunded for any unused gas at the end of the transaction, exchanged at the original rate.

In the case that the sender does not provide the necessary gas to execute the transaction, the transaction runs out of gas and is considered invalid. In this case, the transaction processing aborts and any state changes that occurred are reversed, such that we end up back at the state of Ethereum prior to the transaction. Additionally, a record of the transaction failing gets recorded, showing what transaction was attempted and where it failed. And since the machine already expended effort to run the calculations before running out of gas, logically, none of the gas is refunded to the sender.

Where exactly does this gas money go? All the money spent on gas by the sender is sent to the beneficiary address, which is typically the miners address. Since miners are expending the effort to run computations and validate transactions, miners receive the gas fee as a reward.

Typically, the higher the gas price the sender is willing to pay, the greater the value the miner derives from the transaction. Thus, the more likely miners will be to select it. In this way, miners are free to choose which transactions they want to validate or ignore. In order to guide senders on what gas price to set, miners have the option of advertising the minimum gas price for which they will execute transactions.

Not only is gas used to pay for computation steps, it is also used to pay for storage usage. The total fee for storage is proportional to the smallest multiple of 32 bytes used.

Fees for storage have some nuanced aspects. For example, since increased storage increases the size of the Ethereum state database on all nodes, theres an incentive to keep the amount of data stored small. For this reason, if a transaction has a step that clears an entry in the storage, the fee for executing that operation of is waived, AND a refund is given for freeing up storage space.

One important aspect of the way the Ethereum works is that every single operation executed by the network is simultaneously effected by every full node. However, computational steps on the Ethereum Virtual Machine are very expensive. Therefore, Ethereum smart contracts are best used for simple tasks, like running simple business logic or verifying signatures and other cryptographic objects, rather than more complex uses, like file storage, email, or machine learning, which can put a strain on the network. Imposing fees prevents users from overtaxing the network.

Ethereum is a Turing complete language. (In short, a Turing machine is a machine that can simulate any computer algorithm (for those not familiar with Turing machines, check out this and this). This allows for loops and makes Ethereum susceptible to the halting problem, a problem in which you cannot determine whether or not a program will run infinitely. If there were no fees, a malicious actor could easily try to disrupt the network by executing an infinite loop within a transaction, without any repercussions. Thus, fees protect the network from deliberate attacks.

You might be thinking, why do we also have to pay for storage? Well, just like computation, storage on the Ethereum network is a cost that the entire network has to take the burden of.

We noted earlier that Ethereum is a transaction-based state machine. In other words, transactions occurring between different accounts are what move the global state of Ethereum from one state to the next.

In the most basic sense, a transaction is a cryptographically signed piece of instruction that is generated by an externally owned account, serialized, and then submitted to the blockchain.

There are two types of transactions: message calls and contract creations (i.e. transactions that create new Ethereum contracts).All transactions contain the following components, regardless of their type:

We learned in the Accounts section that transactionsboth message calls and contract-creating transactionsare always initiated by externally owned accounts and submitted to the blockchain. Another way to think about it is that transactions are what bridge the external world to the internal state of Ethereum.

But this doesnt mean that contracts cant talk to other contracts. Contracts that exist within the global scope of Ethereums state can talk to other contracts within that same scope. The way they do this is via messages or internal transactions to other contracts. We can think of messages or internal transactions as being similar to transactions, with the major difference that they are NOT generated by externally owned accounts. Instead, they are generated by contracts. They are virtual objects that, unlike transactions, are not serialized and only exist in the Ethereum execution environment.

When one contract sends an internal transaction to another contract, the associated code that exists on the recipient contract account is executed.

One important thing to note is that internal transactions or messages dont contain a gasLimit. This is because the gas limit is determined by the external creator of the original transaction (i.e. some externally owned account). The gas limit that the externally owned account sets must be high enough to carry out the transaction, including any sub-executions that occur as a result of that transaction, such as contract-to-contract messages. If, in the chain of transactions and messages, a particular message execution runs out of gas, then that messages execution will revert, along with any subsequent messages triggered by the execution. However, the parent execution does not need to revert.

All transactions are grouped together into blocks. A blockchain contains a series of such blocks that are chained together.

In Ethereum, a block consists of:

What the heck is an ommer? An ommer is a block whose parent is equal to the current blocks parents parent. Lets take a quick dive into what ommers are used for and why a block contains the block headers for ommers.

Because of the way Ethereum is built, block times are much lower (~15 seconds) than those of other blockchains, like Bitcoin (~10 minutes). This enables faster transaction processing. However, one of the downsides of shorter block times is that more competing block solutions are found by miners. These competing blocks are also referred to as orphaned blocks (i.e. mined blocks do not make it into the main chain).

The purpose of ommers is to help reward miners for including these orphaned blocks. The ommers that miners include must be valid, meaning within the sixth generation or smaller of the present block. After six children, stale orphaned blocks can no longer be referenced (because including older transactions would complicate things a bit).

Ommer blocks receive a smaller reward than a full block. Nonetheless, theres still some incentive for miners to include these orphaned blocks and reap a reward.

Lets get back to blocks for a moment. We mentioned previously that every block has a block header, but what exactly is this?A block header is a portion of the block consisting of:

Notice how every block header contains three trie structures for:

These trie structures are nothing but the Merkle Patricia tries we discussed earlier.

Additionally, there are a few terms from the above description that are worth clarifying. Lets take a look.

Ethereum allows for logs to make it possible to track various transactions and messages. A contract can explicitly generate a log by defining events that it wants to log.

A log entry contains:

Logs are stored in a bloom filter, which stores the endless log data in an efficient manner.

Logs stored in the header come from the log information contained in the transaction receipt. Just as you receive a receipt when you buy something at a store, Ethereum generates a receipt for every transaction. Like youd expect, each receipt contains certain information about the transaction. This receipt includes items like:

The difficulty of a block is used to enforce consistency in the time it takes to validate blocks. The genesis block has a difficulty of 131,072, and a special formula is used to calculate the difficulty of every block thereafter. If a certain block is validated more quickly than the previous block, the Ethereum protocol increases that blocks difficulty.

The difficulty of the block affects the nonce, which is a hash that must be calculated when mining a block, using the proof-of-work algorithm.

The relationship between the blocks difficulty and nonce is mathematically formalized as:

where Hd is the difficulty.

The only way to find a nonce that meets a difficulty threshold is to use the proof-of-work algorithm to enumerate all of the possibilities. The expected time to find a solution is proportional to the difficultythe higher the difficulty, the harder it becomes to find the nonce, and so the harder it is to validate the block, which in turn increases the time it takes to validate a new block. So, by adjusting the difficulty of a block, the protocol can adjust how long it takes to validate a block.

If, on the other hand, validation time is getting slower, the protocol decreases the difficulty. In this way, the validation time self-adjusts to maintain a constant rateon average, one block every 15 seconds.

Weve come to one of the most complex parts of the Ethereum protocol: the execution of a transaction. Say you send a transaction off into the Ethereum network to be processed. What happens to transition the state of Ethereum to include your transaction?

First, all transactions must meet an initial set of requirements in order to be executed. These include:

If the transaction meets all of the above requirements for validity, then we move onto the next step.

First, we deduct the upfront cost of execution from the senders balance, and increase the nonce of the senders account by 1 to account for the current transaction. At this point, we can calculate the gas remaining as the total gas limit for the transaction minus the intrinsic gas used.

Next, the transaction starts executing. Throughout the execution of a transaction, Ethereum keeps track of the substate. This substate is a way to record information accrued during the transaction that will be needed immediately after the transaction completes. Specifically, it contains:

Next, the various computations required by the transaction are processed.

Once all the steps required by the transaction have been processed, and assuming there is no invalid state, the state is finalized by determining the amount of unused gas to be refunded to the sender. In addition to the unused gas, the sender is also refunded some allowance from the refund balance that we described above.

Once the sender is refunded:

Finally, were left with the new state and a set of the logs created by the transaction.

Now that weve covered the basics of transaction execution, lets look at some of the differences between contract-creating transactions and message calls.

Recall that in Ethereum, there are two types of accounts: contract accounts and externally owned accounts. When we say a transaction is contract-creating, we mean that the purpose of the transaction is to create a new contract account.

In order to create a new contract account, we first declare the address of the new account using a special formula. Then we initialize the new account by:

Once we initialize the account, we can actually create the account, using the init code sent with the transaction (see the Transaction and messages section for a refresher on the init code). What happens during the execution of this init code is varied. Depending on the constructor of the contract, it might update the accounts storage, create other contract accounts, make other message calls, etc.

As the code to initialize a contract is executed, it uses gas. The transaction is not allowed to use up more gas than the remaining gas. If it does, the execution will hit an out-of-gas (OOG) exception and exit. If the transaction exits due to an out-of-gas exception, then the state is reverted to the point immediately prior to transaction. The sender is not refunded the gas that was spent before running out.

Boo hoo.

However, if the sender sent any Ether value with the transaction, the Ether value will be refunded even if the contract creation fails. Phew!

If the initialization code executes successfully, a final contract-creation cost is paid. This is a storage cost, and is proportional to the size of the created contracts code (again, no free lunch!) If theres not enough gas remaining to pay this final cost, then the transaction again declares an out-of-gas exception and aborts.

If all goes well and we make it this far without exceptions, then any remaining unused gas is refunded to the original sender of the transaction, and the altered state is now allowed to persist!

Hooray!

The execution of a message call is similar to that of a contract creation, with a few differences.

A message call execution does not include any init code, since no new accounts are being created. However, it can contain input data, if this data was provided by the transaction sender. Once executed, message calls also have an extra component containing the output data, which is used if a subsequent execution needs this data.

Essay: John Rawls and Robert Nozick: liberalism vs …

Image via Wikipedia

These days , in the occasional university philosophy classroom, the differences between Robert Nozicks Anarchy, State, and Utopia (libertarianism) and John Rawls A Theory of Justice (social liberalism) are still discussed vigorously. In order to demonstrate a broad spectrum of possible political philosophies it is necessary to define the outer boundaries, these two treatises stand like sentries at opposite gatesof the polis

John Rawls, A Theory of Justice. Rawls presents an account of justice in the form of two principles: (1) liberty principle= peoples equal basic liberties such as freedom of speech, freedom of conscience (religion), and the right to vote should be maximized, and (2) difference principle= inequalities in social and economic goods are acceptable only if they promote the welfare of the least advantaged members of society. Rawls writes in the social contract tradition. He seeks to define equilibrium points that, when accumulated, form a civil system characterized by what he calls justice as fairness. To get there he deploys an argument whereby people in an original position (state of nature), make decisions (legislate laws) behind a veil of ignorance (of their place in the society rich or poor) using a reasoning technique he calls reflective equilibrium. It goes something like: behind the veil of ignorance, with no knowledge of their own places in civil society, Rawls posits that reasonable people will default to social and economic positions that maximize the prospects for the worst off feed and house the poor in case you happen to become one. Its much like the prisoners dilemma in game theory. By his own words Rawls = left-liberalism.

Robert Nozick, Anarchy, State, and Utopia, libertarian response to Rawls which argues that only a minimal state devoted to the enforcement of contracts and protecting people against crimes like assault, robbery, fraud can be morally justified. Nozick suggests that the fundamental question of political philosophy is not how government should be organized but whether there should be any state at all, he is close to John Locke in that government is legitimate only to the degree that it promotes greater security for life, liberty, and property than would exist in a chaotic, pre-political state of nature. Nozick concludes, however, that the need for security justifies only a minimal, or night-watchman, state, since it cannot be demonstrated that citizens will attain any more security through extensive governmental intervention. (Nozick p.25-27)

the state may not use its coercive apparatus for the purpose of getting some citizens to aid others, or in order to prohibit activities to people for their own good or protection. (Nozick Preface p.ix)

What is IBM Watson supercomputer? – Definition from WhatIs.com

Watson is an IBM supercomputer that combines artificial intelligence (AI) and sophisticated analytical software for optimal performance as a question answering machine. The supercomputer is named for IBMs founder, Thomas J. Watson.

By submitting your personal information, you agree that TechTarget and its partners may contact you regarding relevant content, products and special offers.

You also agree that your personal information may be transferred and processed in the United States, and that you have read and agree to the Terms of Use and the Privacy Policy.

The Watson supercomputer processes at a rate of 80 teraflops (trillion floating-point operations per second). To replicate (or surpass) a high-functioning humans ability to answer questions, Watson accesses 90 servers with a combined data store of over 200 million pages of information, which it processes against six million logic rules. The device and its data are self-contained in a space that could accommodate 10 refrigerators.

Watson's key components include:

Applications for the Watson's underlying cognitive computingtechnologyare almost endless.Because the device can perform text mining and complex analytics on huge volumes of unstructured data, itcan support a search engine or an expert systemwith capabilities far superior to anypreviously existing. In May 2016, BakerHostetler, a century-old Ohio-based law firm, signed a contractfor a legal expert system based on Watson to work with its 50-human bankruptcy team.ROSS can mine data from about a billion text documents, analyze the information and provide precise responses to complicated questions in less than three seconds. Natural language processing allows the system to translate legalese to respond to the lawyers questions. ROSS' creators are adding more legal modules; similar expert systems are transforming medical research.

To showcase its abilities, Watson challenged two top-ranked players on Jeopardy! andbeat champions Ken Jennings and Brad Rutter in 2011. The Watson avatar sat between the two other contestants, as a human competitor would, while its considerable bulk sat on a different floor of the building. Like the other contestants, Watson had no Internet access.

In the practice round, Watson demonstrated a human-like ability for complex wordplay, correctly responding, for example, to Classic candy bar thats a female Supreme Court justice with What is Baby Ruth Ginsburg? Rutter noted that although the retrieval of information is trivial for Watson and difficult for a human, the human is still better at the complex task of comprehension. Nevertheless, machine learning allows Watson to examine its mistakes against the correct answers to see where it erred and so inform future responses.

In an interview during the Jeopardy! practice round, an IBM representative evaded the question of whether Watson might be made broadly available through a Web interface. The representative said that the company was currently more interested in vertical applications such as healthcare and decision support.

What is comparative planetology – Answers.com

1. The objective of comparative stylistics The objective of comparative stylistics is to study the stylistic characteristics of one language in comparison with those of another one. This systematic study offers students a better and deeper knowledge of the features that distinguish one language from another. Examples: - To become penniless /aflasa/ - The Arabs have pioneered in many branches of science /kna lilc arabi assabaqu fi: Satt furuc i al mac rifati/ These are two cases of "transposition." In the first example, the verb /aflasa/ is expressed by a phrase in English, while in the second example the verb "to pioneer" is replaced with a noun /assabaqu/ in Arabic. - He was blown away /dhahaba adrja arriyhi/ This is a case of "modulation," where each language describes the situation from a different viewpoint. While English indicates the means (blown), Arabic does the opposite: the result first /dhahaba/, then the means /adrja arriyhi/. Thus, we have a "chass-crois": Means: blown /adrja arriyhi/ Result: /dhahaba/ away - Give a pint of your blood /tabarrac biqali:lin min damika/ - Before you could say Jack Robinson /fi: tarfati c ayn/ These are two cases of "equivalence" where two languages describe the same situation by using quite different structural and stylistic means. In the first example, the expression "to give a pint," "pint" being a unit of measure for liquids equal to about half a liter, is rendered into Arabic by the equivalent /tabarrac biqali:lin min/ which literally means "donate some of." In the second example, the English idiom "before you could say Jack Robinson," which means "very quickly or suddenly," has an equivalent idiom in Arabic /Fi tarfati c ayn/ which means "in the twinkling of an eye." 2. The scope and limits of comparative stylistics According to Vinay and Darbelnet (1977), the three above-mentioned cases - transposition, modulation and equivalence - in addition to four others, which are borrowing, tracing ("calque"), literal translation and adaptation, constitute the seven techniques of translation. The authors of the book "Stylistique compare du franais et de l'anglais" even consider comparative stylistics as a method of translation (notice the expression, "mthode de traduction," they put under the title on the first page). It is undeniable that comparative stylistics is beneficial to students, since it enables them to identify the characteristics which distinguish their mother language from a foreign one, and hence to perceive the phenomena that endow each languagewith a peculiar genius. Yet, it is arguable that comparative stylistics can explain the process of translation or set forth "laws valid to the two languages concerned" (Vinay and Darbelnet 1977: 20). Since the comparison of two languages requires primarily the performance of translation, we can assert that comparative stylistics is subsequent to translation and not prior to it. Therefore, the seven techniques are no more than means of comparison. If we reconsider the example "he was blown away," it appears that, to translate it into Arabic, one would immediately look for its functional equivalent rather than think of the "technique" to be used, whether it is transposition, modulation or equivalence As a matter of fact, if the translator fails to find the appropriate equivalent in Arabic, /dhahaba adrja arriyhi/, it will be useless to know that this kind of transfer is called "modulation" from a comparative viewpoint. The same thing applies, of course, to the other techniques offered by comparative stylistics. Moreover, comparative stylistics usually suggests only one equivalent among several possible equivalents of a lexical unit or expression. In the previous example, we can say in Arabic: /dhahaba adrja arriyhi/ as well as /c asafat bihi arriyhu/ or /huwa fi: mahabbi arri:hi/, all of which are expressions with the same meaning. Finally, it appears that comparative stylistics, which is mainly interested in establishing correspondences and equivalences in two languages, does not go beyond the limit of language as a whole to reach the mobility of speech and usage. Hence, it can neither foretell the most appropriate equivalents for expressions in context nor embrace all potential cases of translation within the ever-renewable act of communication. The field of translation is indeed far from being limited or confined to linguistic facts, idiomatic expressions or correspondences that may constitute the subject of a comparative study

Litecoin Review – Charlie Lee’s Open Source P2P LTC …

Litecoin is the worlds fourth most popular cryptocurrency by market cap, after bitcoin, Ethereum, and Ripple. Find out everything you need to know about the global decentralized currency today.

Litecoin is a blockchain-based cryptocurrency that works in a similar way to Ethereum and bitcoin. Its a peer-to-peer internet currency that allows for instant, near-zero cost payments to anyone in the world. Its a decentralized payment network that isnt managed by any central authorities. The network, like other blockchains, is secured by mathematics. Individuals can control their own finances without relying on third parties like banks or traditional financial institutions.

The Litecoin.org website describes how the currency doesnt want to work as an alternative to bitcoin, but as a complementary force:

With substantial industry support, trade volume and liquidity, Litecoin is a proven medium of commerce complementary to bitcoin.

One of the first advantages that Litecoin has over bitcoin is its higher transaction volume: the blockchain generates blocks more frequently, which means transactions can be processed more quickly (2.5 minutes as opposed to 10 minutes).

Lets take a closer look at some of Litecoins most prominent features.

Litecoin offers all of the following features:

You can find general information as well as a list of services and exchanges that support Litecoin. General information can be found at the Litecoin Wiki, while up-to-the-minute network stats can be found at Litecoin Block Explorer Charts. Meanwhile, the source code for Litecoin Core is all open and available to anyone through GitHub.

Like most members of the cryptocurrency community, Litecoin is open source software. The software project was released under the MIT/X11 license, which means users have the power to run, modify, and copy the software and to distribute, at your option, modified versions of the software. Litecoin has a transparent release process that facilitates the independent verification of binaries and their corresponding source code.

The Litecoin blockchain can handle higher transaction volume than bitcoin. Thats because the Litecoin blockchain has more frequent block generation. The network supports more transactions without the need to modify the software in the future. As a result, merchants enjoy faster confirmation times while still having the ability to wait for more confirmations when selling bigger ticket items.

Like all good cryptocurrencies, your Litecoins can be encrypted. You can secure your wallet, view transactions, and check your account balance using the Litecoin projects own wallet. Before you spend Litecoins, however, youll need to enter your password.

Mining rewards are a crucial part of any blockchain. With the Litecoin blockchain, miners are currently awarded (as of June 2017) with 25 new Litecoins per block. That amount gets cut in half about once every 4 years (or every 840,000 blocks). The Litecoin network is scheduled to produce 84 million Litecoins, which is 4 times as many currency units as bitcoin.

Litecoin and bitcoin are two very similar cryptocurrencies. Litecoin was originally based on a bitcoin fork, so the two have a common foundation. However, there are some key differences between Litecoin and bitcoin, including:

Litecoin processes blocks every 2.5 minutes, instead of the 10 minutes taken by bitcoins blockchain. There are pros and cons to this processing time: theres a higher probability of orphaned blocks, for example. On the positive side of things, Litecoins faster processing time means a greater resistance to a double spending attack over the same period as bitcoin. However, total work done is also a consideration so if the network has 10 times less computing work done per block than bitcoin, then bitcoins confirmation is about 10 times harder to reverse even though the Litecoin network can add confirmation blocks at a rate four times faster.

Litecoin uses Scrypt in its proof of work algorithm, which is a sequential memory-hard function requiring asymptotically more memory than an algorithm that isnt memory-hard. That generally means you need more memory in your miners compared to blockchains that dont use Scrypt.

The Litecoin blockchain plans to release 84 million Litecoins in total, or four times as many currency as the total supply of bitcoin.

The use of Scrypt was an interesting choice. The purpose of using Scrypt was to allow miners to mine both bitcoin and Litecoin at the same time. It was also chosen as a way to avoid giving an advantage to GPU, FPGA, and ASIC miners over CPU miners. The other component of using the Scrypt algorithm is that FPGA and ASIC devices made for mining Litecoin tend to be more complicated to create and more expensive to produce than they are for bitcoin, which uses SHA-256. This is because the Scrypt hashing scheme is more memory intensive, and ASICs and FPGAs have higher memory requirements as a result.

Litecoin was introduced to the internet in October 2011. The first release occurred on October 7, 2011, via an open source client released on GitHub. Litecoins first release (0.8.5.1) was a fork of the Bitcoin Core client created by Charlie Lee, a former Google employee. The key improvement over Bitcoin was its decreased block generation time (2.5 minutes, instead of 10 minutes with bitcoin).

Other advantages included the increased maximum number of coins, different hashing algorithm (Scrypt-based, instead of SHA-256), and a slightly modified GUI.

Litecoin remained a lesser-known altcoin until around November 2013, when it exploded with growth. The aggregate value of Litecoin surged by 100% within a 24 hour period during that month. By the end of November 2013, Litecoin had a market cap of $1 billion. In early 2017, the currencys market cap stood at around $1.5 billion. As of June 2017, Litecion has a market cap over $2 billion, with a price of around $30 to $40 per token.

Litecoin has also distinguished itself from the cryptocurrency community for other reasons. In May 2017, Litecoin became the first of the top 5 cryptocurrencies (by market cap) to adopt Segregated Witness. Later that month, the company completed the first Lightning Network transaction through Litecoin, when it transferred 0.00000001 LTC from Zurich to San Francisco in under one second.

You can contact the Litecoin project development team at [emailprotected]

Litecoin has remained steady as the worlds fourth most popular cryptocurrency (by market cap). The only currencies ahead of Litecoin in market cap are bitcoin, Ethereum, and Ripple. With a market cap of over $2 billion, Litecoin has grown from a small bitcoin fork project into a giant of the digital economy. You can learn more about Litecoin by visiting Litecoin.org today.

Litecoin Review - Charlie Lee's Open Source P2P LTC ...

3 Ways Litecoin (LTC) Will Grow In 2018

Observers and experts have noticed growing unrest, uncertainty and frustration in the cryptomarket. Even though several coins have been witnessing a price drop/stagnation over the last three months, the industry is attempting to find its place as a technology that had promised innovation but had fallen short on delivering that.

This article highlights the three ways in which Litecoin can grow in 2018 amidst the growing dissatisfaction with blockchain and crypto-derived currencies. The landscape for cryptocurrency beyond this year is obviousthe focus has to switch from price speculation to usability and real-world application. It is important that functionality supersedes profit potential.

Recognition for Litecoin utility

Litecoin has struggled to differentiate itself from Bitcoin for years, partly because of a compliant marketing slant by founder Charlie Lee. But within the past two months, the narrative has started altering. More people are coming to acknowledge Litecoin as a cryptocurrency with real use. The fundamentals of this currencytransaction speeds, fees, and ability to scale through Segwit and lightning networkhave all proved to be superior to Bitcoin at this point. The attributes that make Litecoin a better option that Bitcoin can be subjective. But on grounds of what each currency is attempting to do in terms of technology (be it a digital, decentralized form of money for the transaction) Litecoin has outclassed all other coins. Scaling issues may come to cripple the Litecoins network someday the same way it has with Bitcoin, but the currency has become synonymous with sending and receiving crypto. Most people, when sending Bitcoin from one exchange to another, convert to Litecoin first in order to capitalize on the cost savings and transaction speeds that the latter offers.

Both coins, despite being mirror images in potential use, play a significant role in the expanding cryptocurrency landscape. The shortcomings of Bitcoin are distorting the growth of the cryptocurrency. Until the issues associated with scaling are solved, Litecoin offers a better alternative to the culture and development team of the cryptocurrency is committed to the superior quality utility of Litecoin as a transacting token. Litecoin has continued to be on the forefront of innovations in crypto technology and will continue to lead the way as a transacting currency. Litecoin has had Segwit longer and is very likely to be the first to implement Lightning Network or some other innovative solution.

Adoption of LitePay

Even though there has been a backlash towards LitePay from certain quarters, LitePay is a step in the right direction. While the debit card has been delayed for some time, it still serves as a two-way payment LTC processor that allows both sides of the transaction equation to participate in cryptocurrency. This equips Litecoin with ample marketing and growth potential. Merchants using LitePay instantly become sources of advertisement for LitePay. With the advent of a debit card, Litecoin spenders have an opportunity to elucidate to their friends and colleagues, the potential use for the cryptocurrency. Thus LitePay acts as an immediate and effective avenue for increasing revenue for Litecoin by tapping into a completely new consumer base. It also gives real crypto enthusiasts to use their currency.

Erosion of Bitcoin brand name

For those enthused by the technology and the possibility of cryptocurrency, whether for political, social or innovative reasons, Litecoin becomes a natural anchor. Litecoin is a fork of the original Bitcoin code, with alterations to expand the utility of the currency. The most remarkable features of Litecoin have been the drastically reduced fees and speedier confirmation times. Even the allure surrounding the mysterious Bitcoin founder Satoshi Nakamoto is not that dissimilar than the present state of Litecoin. That is because Charlie Lee has completely detached himself from a financial stake in his project by selling his entire holding of Litecoin. This gives Litecoin a strong developer, advocate, and leader without the uncertainty of motivation determining its performance. Charlie Lee is growing Litecoin, regardless of its price. Even though investors might find the financial incentive to be a bit lacking to grow Litecoin, but in terms of terms of strategic collaborations with major players like Amazon, the removal of a central authoritarian figure with the potential to become a billionaire is proving to be a positive thing for the Litecoin brand.

While most of the major cryptocurrencies have been at their lowest points since October 2017, Litecoin has managed to gain a step over Ethereum and is just below Ripple in terms of Google trend results. The usability of Litecoin over Bitcoin is evident. Litecoin offers more clarity regarding decentralization and is more representative of cryptocurrency to enthusiasts than XRP, which is deemed by many as a tool for the financial sector. All of these factors have contributed to the growing popularity of Litecoin and could lead to an increase in the further rush for it. The possibility of Litecoin to nab the top spot of popularity away from Bitcoin has bolstered.

Using Psychedelics to Increase Performance and Reprogram …

In a previous post, we discussed the value of nootropics as a tool in the neurohackers toolbox. They can help get us dialed in with laser focus and get things done. They can aid with concentration, learning, and memory. But productivity isnt the only context for the human experience, and it would be sad if we shaped ourselves solely for the purpose of being more effective cogs in a machine. Neurohacking is just as interested in getting better at asking why and what as in building capacity around how.

Enter, psychedelics, empathogens, entheogens and plant medicines. Though many of these chemicals are currently schedule-1 drugs in many countries, humans have been using them for thousands of years for healing, self-inquiry and visioning into the nature of reality. In fact, some propose that the evolution of human consciousness itself was catalyzed by the use of mind-expanding substances discovered or concocted by early man. If neurohacking is about upgrading the hardware our consciousness runs on, we would be remiss not to mention these technologies of altered states.

The rose tinted days of tune in, turn on are long past. Contemporary Neurohackers are exploring these chemicals for everything from accelerated learning to healing major trauma, reprogramming underlying associations that lead to habitual behavioral or thought patterns, shadow work, paradigm engineering, and, of course, the continued exploration of the nature of reality itself.

Below are some introductions to the ways these substances are being used in the neurohacking community.

But first, check out this short video by Jason Silva introducing MAPS (Multidisciplinary Association for Psychedelic Studies) and the concept of programming the psychedelic experience for therapeutic purposes.

Microdosing and Performance Enhancement

Defined as being both both sub-hallucinogenic and sub-perceptual, microdoses of psychedelics are being used by some neurohackers as part of a weekly routine to access higher levels of creativity, increased focus, and improvements in stamina, response time, and physical acuity.

Silicon Valley entrepreneurs looking for a creative edge, as well as extreme sports enthusiasts wanting to enhance athletic prowess, have reported experiencing these benefits without feeling negatively altered. Users have also reported success with microdosing to alleviate depression, cluster headaches, smoking cessation, and ADD/ADHD.

Dr. James Fadiman, Ph.D., is one of the leading researchers in microdosing today. After collecting and reviewing user reports since 2010, hes found that the overwhelming majority of people have reported overall enhancement of well-being, emotional balance, and spiritual awareness. His research to date has been synthesized in The Psychedelic Explorers Guide, which provides guidelines for experimenting with microdosing. While further research is sorely needed, the potential is there for microdosing to become an alternative to addictive prescription antidepressants, anti-anxiety medications and mood stabilizers.

Psychedelics and Reframing the Past

Some of the foundational work done on the psychotherapeutic benefits of psychedelics for trauma healing comes from Stanislov Grof. He pioneered LSD-assisted psychotherapy in the 60s, showing how the appropriate conjunction of therapy with psychedelics could accelerate the rate of healing. He did a lot of early neurohacking experimentation as well, like using strobe light entrainment and psychedelics together to induce mystical experiences.

One version of therapy he developed concerns reframing work on past psychological traumas. Neuroscience has shown us that we dont remember original data or events so much as we remember the way we remember it. And every time we recall something from the past, we actually change the memory. The idea of reframing is to take advantage of this fact and to deliberately go in and change the way we remember some event.

Visualize some event from your past, go into the feeling of that moment, and then visualize yourself doing it differently. For example, standing up for yourself when you hadnt, saying no, etc. The more intensely you can recollect the event and the more real your visualization, the more powerfully you can rewire your brain. Psychedelics can dramatically increase the intensity of your recollection - can bring the event right back into the present and give you authorship over how you want to respond to those events. You cant change an event from the past - but you can change the meaning of that event for your present.

Empathogens and Changing Habits

For better and worse, one of the principle tools of the mind is habituation. As we proceed through life, our brain is constantly compressing complex behaviours and relationships into simple habits that require little to no conscious thought. This is true whether those habits and unconscious associations are healthy and desirable or not. If some event in your past connected feelings of embarrassment, shame or disgust to some thing or situation, you will find yourself hard-wired to avoid that thing or situation - even if you consciously want to go there.

Using empathogens, we can deliberately rewire these associations. By taking a chemical that combines neuroplasticity with pleasure and then thinking about or engaging with things you have negative associations with, you can permanently change your associative state.

One of the places this was pioneered was MDMA-assisted shadow work. A person recalls an event in their past that makes them feel some strong negative emotion every time it comes to mind. They take MDMA, an empathogen that decreases aversion/fear responses and increases emotional openness and empathy, and can experience the memory with a different understanding. The next time they remember that event, they find that they simply dont feel the same way, and that some psychological and emotional damage has been healed. This technique is so powerful that MAPS has demonstrated that MDMA-assisted psychotherapy is perhaps the best current treatment for the deep trauma of PTSD.

But this kind of hack isnt just for deep trauma. Thoughtful Neurohackers have used it to edit habits as prosaic as procrastination and fear of public speaking. Always procrastinate around cleaning your house? Terrified of public speaking? It is currently possible (and someday it might be legal) to choose to take an empathogen, associate the resulting highly positive state with cleaning or speaking, and permanently reduce or eliminate the anxiety you used to associate with that activity.

Entheogens and Spiritual Experience

Of course, no discussion of these chemicals would be complete without discussing their use for exploring the divine within. After all, these are the substances that have been used in religious contexts by shamans for thousands of years. Here is Jason Silva again, on Entering Godmode.

There is no reason to be shy here. Profound spiritual experiences are, well, profound and life-altering and, as a consequence, have played a rather important role in human history. Yet, for a number of reasons, we have largely left them unexamined or languishing in woo-land. Neurohackers know, however, that psilocybin mushrooms can reliably bring people to the single most spiritually significant experience in their lifetimes and some of them are using these technologies to dive purposefully into the big questions.

N,N-DMT for example is being used in studies of philosophy of mind and phenomenology. We know that, independent of their histories or backgrounds, many people who take N,N-DMT report similar, particular subjective experiences. What does this say about the nature of the brain? What might it say about the nature of the mind? Or perhaps of reality itself? We dont know, but these are ancient philosophical questions that can be examined from a very different perspective using mind altering substances.

Conclusion

Psychedelics are powerful tools for transformation, and when used appropriately, can be powerful tools for good. But if youve been reading all of this skeptically and noting all of the potential for harm - accidental or purposeful - that these powerful chemicals can deliver, you are right. These are extremely potent tools and are not to be taken lightly. Weve all heard the horror stories of bad trips, where things get too intense and without the right guidance or help, bad things happen. With great power comes great responsibility.

Unfortunately, for five decades society has chosen to try to avoid, ignore and repress these tools - rather than learn how to use them responsibly. Things are starting to turn around, but we are still waiting for society to catch up and for more rigorous (and legal) research to be allowed to happen.In the meantime, here are some organizations and individuals doing great work in understanding how to safely and effectively use these tools in conjunction with psychotherapies to probe ones patterns, heal traumas and overcome fears that prevent us from getting the most out of our short time in this life.

Using Psychedelics to Increase Performance and Reprogram ...

Ethics – Wikipedia

Ethics or moral philosophy is a branch of philosophy that involves systematizing, defending, and recommending concepts of right and wrong conduct.[1] The term ethics derives from Ancient Greek (ethikos), from (ethos), meaning 'habit, custom'. The branch of philosophy axiology comprises the sub-branches of ethics and aesthetics, each concerned with values.[2]

Ethics seeks to resolve questions of human morality by defining concepts such as good and evil, right and wrong, virtue and vice, justice and crime. As a field of intellectual enquiry, moral philosophy also is related to the fields of moral psychology, descriptive ethics, and value theory.

Three major areas of study within ethics recognized today are:[1]

Rushworth Kidder states that "standard definitions of ethics have typically included such phrases as 'the science of the ideal human character' or 'the science of moral duty'".[3] Richard William Paul and Linda Elder define ethics as "a set of concepts and principles that guide us in determining what behavior helps or harms sentient creatures".[4] The Cambridge Dictionary of Philosophy states that the word "ethics" is "commonly used interchangeably with 'morality'... and sometimes it is used more narrowly to mean the moral principles of a particular tradition, group or individual."[5] Paul and Elder state that most people confuse ethics with behaving in accordance with social conventions, religious beliefs and the law and don't treat ethics as a stand-alone concept.[4]

The word ethics in English refers to several things.[6] It can refer to philosophical ethics or moral philosophya project that attempts to use reason to answer various kinds of ethical questions. As the English philosopher Bernard Williams writes, attempting to explain moral philosophy: "What makes an inquiry a philosophical one is reflective generality and a style of argument that claims to be rationally persuasive."[7] Williams describes the content of this area of inquiry as addressing the very broad question, "how one should live".[8] Ethics can also refer to a common human ability to think about ethical problems that is not particular to philosophy. As bioethicist Larry Churchill has written: "Ethics, understood as the capacity to think critically about moral values and direct our actions in terms of such values, is a generic human capacity."[9] Ethics can also be used to describe a particular person's own idiosyncratic principles or habits.[10] For example: "Joe has strange ethics."

The English word "ethics" is derived from an Ancient Greek word, thikos, which means "relating to one's character". The Ancient Greek adjective thikos is itself derived from another Greek word, the noun thos meaning "character, disposition".[11]

Meta-ethics asks how we understand, know about, and what we mean when we talk about what is right and what is wrong.[12] An ethical question fixed on some particular practical questionsuch as, "Should I eat this particular piece of chocolate cake?"cannot be a meta-ethical question. A meta-ethical question is abstract and relates to a wide range of more specific practical questions. For example, "Is it ever possible to have secure knowledge of what is right and wrong?" would be a meta-ethical question.

Meta-ethics has always accompanied philosophical ethics. For example, Aristotle implies that less precise knowledge is possible in ethics than in other spheres of inquiry, and he regards ethical knowledge as depending upon habit and acculturation in a way that makes it distinctive from other kinds of knowledge. Meta-ethics is also important in G.E. Moore's Principia Ethica from 1903. In it he first wrote about what he called the naturalistic fallacy. Moore was seen to reject naturalism in ethics, in his Open Question Argument. This made thinkers look again at second order questions about ethics. Earlier, the Scottish philosopher David Hume had put forward a similar view on the difference between facts and values.

Studies of how we know in ethics divide into cognitivism and non-cognitivism; this is quite akin to the thing called descriptive and non descriptive . Non-cognitivism is the claim that when we judge something as right or wrong, this is neither true nor false. We may, for example, be only expressing our emotional feelings about these things.[13] Cognitivism can then be seen as the claim that when we talk about right and wrong, we are talking about matters of fact.

The ontology of ethics is about value-bearing things or properties, i.e. the kind of things or stuff referred to by ethical propositions. Non-descriptivists and non-cognitivists believe that ethics does not need a specific ontology since ethical propositions do not refer. This is known as an anti-realist position. Realists, on the other hand, must explain what kind of entities, properties or states are relevant for ethics, how they have value, and why they guide and motivate our actions.[14]

Normative ethics is the study of ethical action. It is the branch of ethics that investigates the set of questions that arise when considering how one ought to act, morally speaking. Normative ethics is distinct from meta-ethics because normative ethics examines standards for the rightness and wrongness of actions, while meta-ethics studies the meaning of moral language and the metaphysics of moral facts.[12] Normative ethics is also distinct from descriptive ethics, as the latter is an empirical investigation of people's moral beliefs. To put it another way, descriptive ethics would be concerned with determining what proportion of people believe that killing is always wrong, while normative ethics is concerned with whether it is correct to hold such a belief. Hence, normative ethics is sometimes called prescriptive, rather than descriptive. However, on certain versions of the meta-ethical view called moral realism, moral facts are both descriptive and prescriptive at the same time.[15]

Traditionally, normative ethics (also known as moral theory) was the study of what makes actions right and wrong. These theories offered an overarching moral principle one could appeal to in resolving difficult moral decisions.

At the turn of the 20th century, moral theories became more complex and were no longer concerned solely with rightness and wrongness, but were interested in many different kinds of moral status. During the middle of the century, the study of normative ethics declined as meta-ethics grew in prominence. This focus on meta-ethics was in part caused by an intense linguistic focus in analytic philosophy and by the popularity of logical positivism.

In 1971, John Rawls published A Theory of Justice, noteworthy in its pursuit of moral arguments and eschewing of meta-ethics.

Virtue ethics describes the character of a moral agent as a driving force for ethical behavior, and it is used to describe the ethics of Socrates, Aristotle, and other early Greek philosophers. Socrates (469399 BC) was one of the first Greek philosophers to encourage both scholars and the common citizen to turn their attention from the outside world to the condition of humankind. In this view, knowledge bearing on human life was placed highest, while all other knowledge was secondary. Self-knowledge was considered necessary for success and inherently an essential good. A self-aware person will act completely within his capabilities to his pinnacle, while an ignorant person will flounder and encounter difficulty. To Socrates, a person must become aware of every fact (and its context) relevant to his existence, if he wishes to attain self-knowledge. He posited that people will naturally do what is good if they know what is right. Evil or bad actions are the results of ignorance. If a criminal was truly aware of the intellectual and spiritual consequences of his or her actions, he or she would neither commit nor even consider committing those actions. Any person who knows what is truly right will automatically do it, according to Socrates. While he correlated knowledge with virtue, he similarly equated virtue with joy. The truly wise man will know what is right, do what is good, and therefore be happy.[16]:3233

Aristotle (384323BC) posited an ethical system that may be termed "virtuous". In Aristotle's view, when a person acts in accordance with virtue this person will do good and be content. Unhappiness and frustration are caused by doing wrong, leading to failed goals and a poor life. Therefore, it is imperative for people to act in accordance with virtue, which is only attainable by the practice of the virtues in order to be content and complete. Happiness was held to be the ultimate goal. All other things, such as civic life or wealth, were only made worthwhile and of benefit when employed in the practice of the virtues. The practice of the virtues is the surest path to happiness.

Aristotle asserted that the soul of man had three natures: body (physical/metabolism), animal (emotional/appetite), and rational (mental/conceptual). Physical nature can be assuaged through exercise and care; emotional nature through indulgence of instinct and urges; and mental nature through human reason and developed potential. Rational development was considered the most important, as essential to philosophical self-awareness and as uniquely human. Moderation was encouraged, with the extremes seen as degraded and immoral. For example, courage is the moderate virtue between the extremes of cowardice and recklessness. Man should not simply live, but live well with conduct governed by virtue. This is regarded as difficult, as virtue denotes doing the right thing, in the right way, at the right time, for the right reason.

The Stoic philosopher Epictetus posited that the greatest good was contentment and serenity. Peace of mind, or Apatheia, was of the highest value; self-mastery over one's desires and emotions leads to spiritual peace. The "unconquerable will" is central to this philosophy. The individual's will should be independent and inviolate. Allowing a person to disturb the mental equilibrium is, in essence, offering yourself in slavery. If a person is free to anger you at will, you have no control over your internal world, and therefore no freedom. Freedom from material attachments is also necessary. If a thing breaks, the person should not be upset, but realize it was a thing that could break. Similarly, if someone should die, those close to them should hold to their serenity because the loved one was made of flesh and blood destined to death. Stoic philosophy says to accept things that cannot be changed, resigning oneself to the existence and enduring in a rational fashion. Death is not feared. People do not "lose" their life, but instead "return", for they are returning to God (who initially gave what the person is as a person). Epictetus said difficult problems in life should not be avoided, but rather embraced. They are spiritual exercises needed for the health of the spirit, just as physical exercise is required for the health of the body. He also stated that sex and sexual desire are to be avoided as the greatest threat to the integrity and equilibrium of a man's mind. Abstinence is highly desirable. Epictetus said remaining abstinent in the face of temptation was a victory for which a man could be proud.[16]:3841

Modern virtue ethics was popularized during the late 20th century in large part as a response to G. E. M. Anscombe's "Modern Moral Philosophy". Anscombe argues that consequentialist and deontological ethics are only feasible as universal theories if the two schools ground themselves in divine law. As a deeply devoted Christian herself, Anscombe proposed that either those who do not give ethical credence to notions of divine law take up virtue ethics, which does not necessitate universal laws as agents themselves are investigated for virtue or vice and held up to "universal standards", or that those who wish to be utilitarian or consequentialist ground their theories in religious conviction.[17] Alasdair MacIntyre, who wrote the book After Virtue, was a key contributor and proponent of modern virtue ethics, although MacIntyre supports a relativistic account of virtue based on cultural norms, not objective standards.[17] Martha Nussbaum, a contemporary virtue ethicist, objects to MacIntyre's relativism, among that of others, and responds to relativist objections to form an objective account in her work "Non-Relative Virtues: An Aristotelian Approach".[18] However, Nussbaum's accusation of relativism appears to be a misreading. In Whose Justice, Whose Rationality?, MacIntyre's ambition of taking a rational path beyond relativism was quite clear when he stated "rival claims made by different traditions [] are to be evaluated [] without relativism" (p.354) because indeed "rational debate between and rational choice among rival traditions is possible (p.352). Complete Conduct Principles for the 21st Century[19] blended the Eastern virtue ethics and the Western virtue ethics, with some modifications to suit the 21st Century, and formed a part of contemporary virtue ethics.[19]

Hedonism posits that the principal ethic is maximizing pleasure and minimizing pain. There are several schools of Hedonist thought ranging from those advocating the indulgence of even momentary desires to those teaching a pursuit of spiritual bliss. In their consideration of consequences, they range from those advocating self-gratification regardless of the pain and expense to others, to those stating that the most ethical pursuit maximizes pleasure and happiness for the most people.[16]:37

Founded by Aristippus of Cyrene, Cyrenaics supported immediate gratification or pleasure. "Eat, drink and be merry, for tomorrow we die." Even fleeting desires should be indulged, for fear the opportunity should be forever lost. There was little to no concern with the future, the present dominating in the pursuit of immediate pleasure. Cyrenaic hedonism encouraged the pursuit of enjoyment and indulgence without hesitation, believing pleasure to be the only good.[16]:37

Epicurean ethics is a hedonist form of virtue ethics. Epicurus "...presented a sustained argument that pleasure, correctly understood, will coincide with virtue."[20] He rejected the extremism of the Cyrenaics, believing some pleasures and indulgences to be detrimental to human beings. Epicureans observed that indiscriminate indulgence sometimes resulted in negative consequences. Some experiences were therefore rejected out of hand, and some unpleasant experiences endured in the present to ensure a better life in the future. To Epicurus, the summum bonum, or greatest good, was prudence, exercised through moderation and caution. Excessive indulgence can be destructive to pleasure and can even lead to pain. For example, eating one food too often makes a person lose a taste for it. Eating too much food at once leads to discomfort and ill-health. Pain and fear were to be avoided. Living was essentially good, barring pain and illness. Death was not to be feared. Fear was considered the source of most unhappiness. Conquering the fear of death would naturally lead to a happier life. Epicurus reasoned if there were an afterlife and immortality, the fear of death was irrational. If there was no life after death, then the person would not be alive to suffer, fear or worry; he would be non-existent in death. It is irrational to fret over circumstances that do not exist, such as one's state of death in the absence of an afterlife.[16]:3738

State consequentialism, also known as Mohist consequentialism,[21] is an ethical theory that evaluates the moral worth of an action based on how much it contributes to the basic goods of a state.[21] The Stanford Encyclopedia of Philosophy describes Mohist consequentialism, dating back to the 5th century BC, as "a remarkably sophisticated version based on a plurality of intrinsic goods taken as constitutive of human welfare".[22] Unlike utilitarianism, which views pleasure as a moral good, "the basic goods in Mohist consequentialist thinking are... order, material wealth, and increase in population".[23] During Mozi's era, war and famines were common, and population growth was seen as a moral necessity for a harmonious society. The "material wealth" of Mohist consequentialism refers to basic needs like shelter and clothing, and the "order" of Mohist consequentialism refers to Mozi's stance against warfare and violence, which he viewed as pointless and a threat to social stability.[24]

Stanford sinologist David Shepherd Nivison, in The Cambridge History of Ancient China, writes that the moral goods of Mohism "are interrelated: more basic wealth, then more reproduction; more people, then more production and wealth... if people have plenty, they would be good, filial, kind, and so on unproblematically."[23] The Mohists believed that morality is based on "promoting the benefit of all under heaven and eliminating harm to all under heaven". In contrast to Bentham's views, state consequentialism is not utilitarian because it is not hedonistic or individualistic. The importance of outcomes that are good for the community outweigh the importance of individual pleasure and pain.[25]

Consequentialism refers to moral theories that hold the consequences of a particular action form the basis for any valid moral judgment about that action (or create a structure for judgment, see rule consequentialism). Thus, from a consequentialist standpoint, a morally right action is one that produces a good outcome, or consequence. This view is often expressed as the aphorism "The ends justify the means".

The term "consequentialism" was coined by G. E. M. Anscombe in her essay "Modern Moral Philosophy" in 1958, to describe what she saw as the central error of certain moral theories, such as those propounded by Mill and Sidgwick.[26] Since then, the term has become common in English-language ethical theory.

The defining feature of consequentialist moral theories is the weight given to the consequences in evaluating the rightness and wrongness of actions.[27] In consequentialist theories, the consequences of an action or rule generally outweigh other considerations. Apart from this basic outline, there is little else that can be unequivocally said about consequentialism as such. However, there are some questions that many consequentialist theories address:

One way to divide various consequentialisms is by the many types of consequences that are taken to matter most, that is, which consequences count as good states of affairs. According to utilitarianism, a good action is one that results in an increase and positive effect, and the best action is one that results in that effect for the greatest number. Closely related is eudaimonic consequentialism, according to which a full, flourishing life, which may or may not be the same as enjoying a great deal of pleasure, is the ultimate aim. Similarly, one might adopt an aesthetic consequentialism, in which the ultimate aim is to produce beauty. However, one might fix on non-psychological goods as the relevant effect. Thus, one might pursue an increase in material equality or political liberty instead of something like the more ephemeral "pleasure". Other theories adopt a package of several goods, all to be promoted equally. Whether a particular consequentialist theory focuses on a single good or many, conflicts and tensions between different good states of affairs are to be expected and must be adjudicated.

Utilitarianism is an ethical theory that argues the proper course of action is one that maximizes a positive effect, such as "happiness", "welfare", or the ability to live according to personal preferences.[28] Jeremy Bentham and John Stuart Mill are influential proponents of this school of thought. In A Fragment on Government Bentham says 'it is the greatest happiness of the greatest number that is the measure of right and wrong' and describes this as a fundamental axiom. In An Introduction to the Principles of Morals and Legislation he talks of 'the principle of utility' but later prefers "the greatest happiness principle".[29][30]

Utilitarianism is the paradigmatic example of a consequentialist moral theory. This form of utilitarianism holds that the morally correct action is the one that produces the best outcome for all people affected by the action. John Stuart Mill, in his exposition of utilitarianism, proposed a hierarchy of pleasures, meaning that the pursuit of certain kinds of pleasure is more highly valued than the pursuit of other pleasures.[31] Other noteworthy proponents of utilitarianism are neuroscientist Sam Harris, author of The Moral Landscape, and moral philosopher Peter Singer, author of, amongst other works, Practical Ethics.

There are two types of utilitarianism, act utilitarianism and rule utilitarianism. In act utilitarianism, the principle of utility applies directly to each alternative act in a situation of choice. The right act is the one that brings about the best results (or the least amount of bad results). In rule utilitarianism, the principle of utility determines the validity of rules of conduct (moral principles). A rule like promise-keeping is established by looking at the consequences of a world in which people break promises at will and a world in which promises are binding. Right and wrong are the following or breaking of rules that are sanctioned by their utilitarian value.[32]

Deontological ethics or deontology (from Greek , deon, "obligation, duty"; and -, -logia) is an approach to ethics that determines goodness or rightness from examining acts, or the rules and duties that the person doing the act strove to fulfill.[33] This is in contrast to consequentialism, in which rightness is based on the consequences of an act, and not the act by itself. In deontology, an act may be considered right even if the act produces a bad consequence,[34] if it follows the rule that "one should do unto others as they would have done unto them",[35] and even if the person who does the act lacks virtue and had a bad intention in doing the act.[citation needed] According to deontology, people have a duty to act in a way that does those things that are inherently good as acts ("truth-telling" for example), or follow an objectively obligatory rule (as in rule utilitarianism). For deontologists, the ends or consequences of people's actions are not important in and of themselves, and people's intentions are not important in and of themselves.

Immanuel Kant's theory of ethics is considered deontological for several different reasons.[36][37] First, Kant argues that to act in the morally right way, people must act from duty (deon).[38] Second, Kant argued that it was not the consequences of actions that make them right or wrong but the motives (maxime) of the person who carries out the action. Kant's argument that to act in the morally right way, one must act from duty, begins with an argument that the highest good must be both good in itself, and good without qualification.[39] Something is 'good in itself' when it is intrinsically good, and 'good without qualification' when the addition of that thing never makes a situation ethically worse. Kant then argues that those things that are usually thought to be good, such as intelligence, perseverance and pleasure, fail to be either intrinsically good or good without qualification. Pleasure, for example, appears to not be good without qualification, because when people take pleasure in watching someone suffer, they make the situation ethically worse. He concludes that there is only one thing that is truly good:

Nothing in the worldindeed nothing even beyond the worldcan possibly be conceived which could be called good without qualification except a good will.[39]

Associated with the pragmatists, Charles Sanders Peirce, William James, and especially John Dewey, pragmatic ethics holds that moral correctness evolves similarly to scientific knowledge: socially over the course of many lifetimes. Thus, we should prioritize social reform over attempts to account for consequences, individual virtue or duty (although these may be worthwhile attempts, if social reform is provided for).[40]

Care ethics contrasts with more well-known ethical models, such as consequentialist theories (e.g. utilitarianism) and deontological theories (e.g., Kantian ethics) in that it seeks to incorporate traditionally feminized virtues and values thatproponents of care ethics contendare absent in such traditional models of ethics. These values include the importance of empathetic relationships and compassion.

Care-focused feminism is a branch of feminist thought, informed primarily by ethics of care as developed by Carol Gilligan and Nel Noddings.[41] This body of theory is critical of how caring is socially assigned to women, and consequently devalued. They write, Care-focused feminists regard womens capacity for care as a human strength, that should be taught to and expected of men as well as women. Noddings proposes that ethical caring has the potential to be a more concrete evaluative model of moral dilemma than an ethic of justice.[42] Noddings care-focused feminism requires practical application of relational ethics, predicated on an ethic of care.[43]

Role ethics is an ethical theory based on family roles.[44] Unlike virtue ethics, role ethics is not individualistic. Morality is derived from a person's relationship with their community.[45] Confucian ethics is an example of role ethics[44] though this is not straightforwardly uncontested.[46] Confucian roles center around the concept of filial piety or xiao, a respect for family members.[47] According to Roger Ames and Henry Rosemont, "Confucian normativity is defined by living one's family roles to maximum effect." Morality is determined through a person's fulfillment of a role, such as that of a parent or a child. Confucian roles are not rational, and originate through the xin, or human emotions.[45]

Anarchist ethics is an ethical theory based on the studies of anarchist thinkers. The biggest contributor to the anarchist ethics is the Russian zoologist, geographer, economist, and political activist Peter Kropotkin.

Starting from the premise that the goal of ethical philosophy should be to help humans adapt and thrive in evolutionary terms, Kropotkin's ethical framework uses biology and anthropology as a basis in order to scientifically establish what will best enable a given social order to thrive biologically and socially and advocates certain behavioural practices to enhance humanity's capacity for freedom and well-being, namely practices which emphasise solidarity, equality, and justice.

Kropotkin argues that ethics itself is evolutionary, and is inherited as a sort of a social instinct through cultural history, and by so, he rejects any religious and transcendental explanation of morality. The origin of ethical feeling in both animals and humans can be found, he claims, in the natural fact of "sociality" (mutualistic symbiosis), which humans can then combine with the instinct for justice (i.e. equality) and then with the practice of reason to construct a non-supernatural and anarchistic system of ethics.[48] Kropotkin suggests that the principle of equality at the core of anarchism is the same as the Golden rule:

This principle of treating others as one wishes to be treated oneself, what is it but the very same principle as equality, the fundamental principle of anarchism? And how can any one manage to believe himself an anarchist unless he practices it? We do not wish to be ruled. And by this very fact, do we not declare that we ourselves wish to rule nobody? We do not wish to be deceived, we wish always to be told nothing but the truth. And by this very fact, do we not declare that we ourselves do not wish to deceive anybody, that we promise to always tell the truth, nothing but the truth, the whole truth? We do not wish to have the fruits of our labor stolen from us. And by that very fact, do we not declare that we respect the fruits of others' labor? By what right indeed can we demand that we should be treated in one fashion, reserving it to ourselves to treat others in a fashion entirely different? Our sense of equality revolts at such an idea.[49]

The 20th century saw a remarkable expansion and evolution of critical theory, following on earlier Marxist Theory efforts to locate individuals within larger structural frameworks of ideology and action.

Antihumanists such as Louis Althusser, Michel Foucault and structuralists such as Roland Barthes challenged the possibilities of individual agency and the coherence of the notion of the 'individual' itself. This was a on the basis that personal identity was, at least in part, a social construction. As critical theory developed in the later 20th century, post-structuralism sought to problematize human relationships to knowledge and 'objective' reality. Jacques Derrida argued that access to meaning and the 'real' was always deferred, and sought to demonstrate via recourse to the linguistic realm that "there is no outside-text/non-text" ("il n'y a pas de hors-texte" is often mistranslated as "there is nothing outside the text"); at the same time, Jean Baudrillard theorised that signs and symbols or simulacra mask reality (and eventually the absence of reality itself), particularly in the consumer world.

Post-structuralism and postmodernism argue that ethics must study the complex and relational conditions of actions. A simple alignment of ideas of right and particular acts is not possible. There will always be an ethical remainder that cannot be taken into account or often even recognized. Such theorists find narrative (or, following Nietzsche and Foucault, genealogy) to be a helpful tool for understanding ethics because narrative is always about particular lived experiences in all their complexity rather than the assignment of an idea or norm to separate and individual actions.

Zygmunt Bauman says postmodernity is best described as modernity without illusion, the illusion being the belief that humanity can be repaired by some ethic principle. Postmodernity can be seen in this light as accepting the messy nature of humanity as unchangeable.

David Couzens Hoy states that Emmanuel Levinas's writings on the face of the Other and Derrida's meditations on the relevance of death to ethics are signs of the "ethical turn" in Continental philosophy that occurred in the 1980s and 1990s. Hoy describes post-critique ethics as the "obligations that present themselves as necessarily to be fulfilled but are neither forced on one or are enforceable" (2004, p.103).

Hoy's post-critique model uses the term ethical resistance. Examples of this would be an individual's resistance to consumerism in a retreat to a simpler but perhaps harder lifestyle, or an individual's resistance to a terminal illness. Hoy describes Levinas's account as "not the attempt to use power against itself, or to mobilize sectors of the population to exert their political power; the ethical resistance is instead the resistance of the powerless"(2004, p.8).

Hoy concludes that

The ethical resistance of the powerless others to our capacity to exert power over them is therefore what imposes unenforceable obligations on us. The obligations are unenforceable precisely because of the other's lack of power. That actions are at once obligatory and at the same time unenforceable is what put them in the category of the ethical. Obligations that were enforced would, by the virtue of the force behind them, not be freely undertaken and would not be in the realm of the ethical. (2004, p. 184)

Applied ethics is a discipline of philosophy that attempts to apply ethical theory to real-life situations. The discipline has many specialized fields, such as engineering ethics, bioethics, geoethics, public service ethics and business ethics.

Applied ethics is used in some aspects of determining public policy, as well as by individuals facing difficult decisions. The sort of questions addressed by applied ethics include: "Is getting an abortion immoral?" "Is euthanasia immoral?" "Is affirmative action right or wrong?" "What are human rights, and how do we determine them?" "Do animals have rights as well?" and "Do individuals have the right of self-determination?"[12]

A more specific question could be: "If someone else can make better out of his/her life than I can, is it then moral to sacrifice myself for them if needed?" Without these questions, there is no clear fulcrum on which to balance law, politics, and the practice of arbitrationin fact, no common assumptions of all participantsso the ability to formulate the questions are prior to rights balancing. But not all questions studied in applied ethics concern public policy. For example, making ethical judgments regarding questions such as, "Is lying always wrong?" and, "If not, when is it permissible?" is prior to any etiquette.

People, in general, are more comfortable with dichotomies (two opposites). However, in ethics, the issues are most often multifaceted and the best-proposed actions address many different areas concurrently. In ethical decisions, the answer is almost never a "yes or no", "right or wrong" statement. Many buttons are pushed so that the overall condition is improved and not to the benefit of any particular faction.

Bioethics is the study of controversial ethics brought about by advances in biology and medicine. Bioethicists are concerned with the ethical questions that arise in the relationships among life sciences, biotechnology, medicine, politics, law, and philosophy. It also includes the study of the more commonplace questions of values ("the ethics of the ordinary") that arise in primary care and other branches of medicine.

Bioethics also needs to address emerging biotechnologies that affect basic biology and future humans. These developments include cloning, gene therapy, human genetic engineering, astroethics and life in space,[50] and manipulation of basic biology through altered DNA, RNA and proteins, e.g. "three parent baby, where baby is born from genetically modified embryos, would have DNA from a mother, a father and from a female donor.[51] Correspondingly, new bioethics also need to address life at its core. For example, biotic ethics value organic gene/protein life itself and seek to propagate it.[52] With such life-centered principles, ethics may secure a cosmological future for life.[53]

Business ethics (also corporate ethics) is a form of applied ethics or professional ethics that examines ethical principles and moral or ethical problems that arise in a business environment, including fields like medical ethics. Business ethics represents the practices that any individual or group exhibits within an organization that can negatively or positively affect the businesses core values. It applies to all aspects of business conduct and is relevant to the conduct of individuals and entire organizations.

Business ethics has both normative and descriptive dimensions. As a corporate practice and a career specialization, the field is primarily normative. Academics attempting to understand business behavior employ descriptive methods. The range and quantity of business ethical issues reflect the interaction of profit-maximizing behavior with non-economic concerns. Interest in business ethics accelerated dramatically during the 1980s and 1990s, both within major corporations and within academia. For example, today most major corporations promote their commitment to non-economic values under headings such as ethics codes and social responsibility charters. Adam Smith said, "People of the same trade seldom meet together, even for merriment and diversion, but the conversation ends in a conspiracy against the public, or in some contrivance to raise prices."[54] Governments use laws and regulations to point business behavior in what they perceive to be beneficial directions. Ethics implicitly regulates areas and details of behavior that lie beyond governmental control.[55] The emergence of large corporations with limited relationships and sensitivity to the communities in which they operate accelerated the development of formal ethics regimes.[56][57]

In Moral Machines: Teaching Robots Right from Wrong, Wendell Wallach and Colin Allen conclude that issues in machine ethics will likely drive advancement in understanding of human ethics by forcing us to address gaps in modern normative theory and by providing a platform for experimental investigation.[58] The effort to actually program a machine or artificial agent to behave as though instilled with a sense of ethics requires new specificity in our normative theories, especially regarding aspects customarily considered common-sense. For example, machines, unlike humans, can support a wide selection of learning algorithms, and controversy has arisen over the relative ethical merits of these options. This may reopen classic debates of normative ethics framed in new (highly technical) terms.

Military ethics are concerned with questions regarding the application of force and the ethos of the soldier and are often understood as applied professional ethics.[59] Just war theory is generally seen to set the background terms of military ethics. However individual countries and traditions have different fields of attention.[60]

Military ethics involves multiple subareas, including the following among others:

Political ethics (also known as political morality or public ethics) is the practice of making moral judgements about political action and political agents.[61]

Public sector ethics is a set of principles that guide public officials in their service to their constituents, including their decision-making on behalf of their constituents. Fundamental to the concept of public sector ethics is the notion that decisions and actions are based on what best serves the public's interests, as opposed to the official's personal interests (including financial interests) or self-serving political interests.[62]

Publication ethics is the set of principles that guide the writing and publishing process for all professional publications. To follow these principles, authors must verify that the publication does not contain plagiarism or publication bias.[63] As a way to avoid misconduct in research these principles can also apply to experiments that are referenced or analyzed in publications by ensuring the data is recorded honestly and accurately.[64]

Plagiarism is the failure to give credit to another authors work or ideas, when it is used in the publication.[65] It is the obligation of the editor of the journal to ensure the article does not contain any plagiarism before it is published.[66] If a publication that has already been published is proven to contain plagiarism, the editor of the journal can retract the article.[67]

Publication bias occurs when the publication is one-sided or "prejudiced against results".[68] In best practice, an author should try to include information from all parties involved, or affected by the topic. If an author is prejudiced against certain results, than it can "lead to erroneous conclusions being drawn".[69]

Misconduct in research can occur when an experimenter falsifies results.[70] Falsely recorded information occurs when the researcher "fakes" information or data, which was not used when conducting the actual experiment.[70] By faking the data, the researcher can alter the results from the experiment to better fit the hypothesis they originally predicted. When conducting medical research, it is important to honor the healthcare rights of a patient by protecting their anonymity in the publication.[63] Respect for autonomy is the principle that decision-making should allow individuals to be autonomous; they should be able to make decisions that apply to their own lives. This means that individuals should have control of their lives. Justice is the principle that decision-makers must focus on actions that are fair to those affected. Ethical decisions need to be consistent with the ethical theory. There are cases where the management has made decisions that seem to be unfair to the employees, shareholders, and other stakeholders (Solomon, 1992, pp49). Such decisions are unethical.

Relational ethics are related to an ethics of care.[71]:6263 They are used in qualitative research, especially ethnography and autoethnography. Researchers who employ relational ethics value and respect the connection between themselves and the people they study, and "...between researchers and the communities in which they live and work." (Ellis, 2007, p.4).[72] Relational ethics also help researchers understand difficult issues such as conducting research on intimate others that have died and developing friendships with their participants.[73][74] Relational ethics in close personal relationships form a central concept of contextual therapy.

Animal ethics is a term used in academia to describe human-animal relationships and how animals ought to be treated. The subject matter includes animal rights, animal welfare, animal law, speciesism, animal cognition, wildlife conservation, the moral status of nonhuman animals, the concept of nonhuman personhood, human exceptionalism, the history of animal use, and theories of justice.

Moral psychology is a field of study that began as an issue in philosophy and that is now properly considered part of the discipline of psychology. Some use the term "moral psychology" relatively narrowly to refer to the study of moral development.[75] However, others tend to use the term more broadly to include any topics at the intersection of ethics and psychology (and philosophy of mind).[76] Such topics are ones that involve the mind and are relevant to moral issues. Some of the main topics of the field are moral responsibility, moral development, moral character (especially as related to virtue ethics), altruism, psychological egoism, moral luck, and moral disagreement.[77]

Evolutionary ethics concerns approaches to ethics (morality) based on the role of evolution in shaping human psychology and behavior. Such approaches may be based in scientific fields such as evolutionary psychology or sociobiology, with a focus on understanding and explaining observed ethical preferences and choices.[78]

Descriptive ethics is on the less philosophical end of the spectrum since it seeks to gather particular information about how people live and draw general conclusions based on observed patterns. Abstract and theoretical questions that are more clearly philosophicalsuch as, "Is ethical knowledge possible?"are not central to descriptive ethics. Descriptive ethics offers a value-free approach to ethics, which defines it as a social science rather than a humanity. Its examination of ethics doesn't start with a preconceived theory but rather investigates observations of actual choices made by moral agents in practice. Some philosophers rely on descriptive ethics and choices made and unchallenged by a society or culture to derive categories, which typically vary by context. This can lead to situational ethics and situated ethics. These philosophers often view aesthetics, etiquette, and arbitration as more fundamental, percolating "bottom up" to imply the existence of, rather than explicitly prescribe, theories of value or of conduct. The study of descriptive ethics may include examinations of the following:

Litecoin Courting TenX and Korbit – Just a Month after …

Just a month after LitePays untimely collapse, Litecoin has teamed up with a well-known wallet platform and a large South Korean cryptocurrency exchange.

Despite the disappointment of LitePays demise, TenX have announced Litecoin (LTC) support in on its wallet platform while South Koreas second biggest exchange Korbit launched Litecoin trading on 18 April.

It comes as a timely boon for the cryptocurrency and the Litecoin Foundation, which had been eagerly anticipating and supporting the development of LitePay - before it ceased operations without its product being launched in March.

TenX launched LTC on its wallet platforms without an official announcement last week, to ease the pressure on its systems while it finalized live testing.

Furthermore, TenX have stepped up and hope to provide a card service for Litecoin, one of the features LitePay had promised during its failed development:

We are also excited to announce a new partnership; we have reached out to, and are working with the Litecoin Foundation to introduce a co-branded card for which more information will be available soon. We hope to become the preferred payment platform for fans and owners of Litecoin.

Korbits support of Litecoin coincides with a slight uptrend in value since a recent low at the start of April. As per Coinmarketcap data, Litecoin is trading at $140.36.

Litecoin founder Charlie Lee celebrated the move on Twitter, highlighting the fact that hed try to get Korbit to support the cryptocurrency years ago:

LitePay promised to give users the ability to accept payments in Litecoin which facilitated an instantaneous conversion to fiat currency which could then be deposited to a conventional bank account in over 38 countries.

Furthermore LitePay was touting a 1 percent transaction fee, which it claimed would beat conventional credit card rates.

Souce: LitePay/Twitter

Unfortunately, none of this ever materialized, as Litecoin Foundation director of operations Keith Yong confirmed the news on March 26 that he had stopped development and would be selling the company.

Yong expressed his dissatisfaction with the state of affairs in an official announcement on the website.

The launch of the project was met with cautious optimism late in 2017 with an ambitious launch date set for Feb. 26 which has since come and gone.

For the public, things came undone when Litepay CEO Kenneth Asare opened himself to an Ask Me Anything (AMA) session on Reddit on March 17. What hed probably planned to be a candid public engagement for the project spelled the beginning of the end.

Seasoned cryptocurrency community members, made up of well-informed developers and the likes, tore into Asare as he struggled to answer a slew of questions about the project.

Particular sore points were a lack of transparency on the team, the privacy policy being copied from Coinbase as well as the fact that Asare would not share developer documentation.

One user, cdm9002 labelled Asares website a scam and challenged the LitePay CEO to convince him that his project was real.

Another user pointed out that the original privacy policy on the LitePay website was a verbatim copy from the Coinbase website, before this was amended:

I stand corrected. They changed their privacy policy. Up until very recently, it was a copy/paste from Coinbase but they replaced "Coinbase" with "LitePay".

For the Litecoin Foundation, alarm bells started ringing when the LitePay CEO asked for further funding for the project. Failing to disclose how initial funding had been spent, the NPO refused to assist with further investment according to Yong:

Prior to that, the foundation had approached Kenneth regarding his less than transparent nature with the company and to express our, and the communitys, concerns regarding his recent Reddit AMA.

It was at this time that Kenneth asked the foundation for more funds to continue operations. The foundation refused any further funding as he was unable to provide a satisfactory picture of where the money had been spent and refused to go into exact details about the company and show objective evidence to back up his statements.

Litecoin founder Charlie Lee also took to Twitter, apologising to the Litecoin and wider cryptocurrency community:

Cointelegraph reached out to Lee for comment, but the Litecoin founder declined to give any further thoughts on the matter.

There has been no official announcement outlining why Asare decided to pack up shop - but these factors seemed to have played a role:

While its not clear how much money Asare raised for the development of LitePay in total, Litecoin Foundation director Xinxi Wang is understood to have invested $50.000 into the project:

As Wang suggests, the monetary losses are far outweighed by the damage to Asares career in the wake of LitePays failure.

Given that the developer squandered the capital investment from Wang and the Litecoin Foundation, they werent about to keep handing out further investments.

While Charlie Lee said that a lack of due diligence was negligent on their part, Wang explained on Twitter that he felt Asares entrepreneurial track record gave the project credibility:

In Asares AMA session on Reddit, he claimed to have studied law before owning and operating a number of businesses in the late decade. This included an education infrastructure company that built a type of School Management System, a Construction Defect Claims Management company as well as a Collaborative Learning Social Network.

Litepays demise is no less saddening than any other business that has failed to live up to expectations but a slight consolation is the fact that it doesnt seem to have been an outright scam.

The project was not funding by an initial coin offering (ICO) which means plucky investors were saved from Asares abrupt decision to pack up shop.

Its a far cry from a number of ICOs that have ended up scamming people out of a lot money.

As ICORatings Brian Keen points out in a recent column on Cointelegraph, there have been a number of outrageous exit scams that have left investors out of pocket.

The likes of Plexcoin and its owner Dominic Lacroix set the bar pretty high in terms of how far some fraudsters are willing to go to steal from unsuspecting investors.

In that case, Lacroix nearly ran off with $15 mln, before the US Securities and Exchange Commission (SEC) stepped in and froze the accounts of the company. Lacroix ended up in prison before he could run off with the millions hed raised during the ICO.

Litepays downfall could be more closely attributed to the end of Ethereums Decentralized Autnomous Organisation (DAO) project in 2017.

The brainchild of Ethereum founder Vitalik Buterin, the DAO project promised to create a revolutionary funding model for Decentralised Apps (DApps) on the Ethereum blockchain. The project was launched and raised $150 mln in Eth tokens.

However, shortly after its launch, hackers found an exploit in the code and stole $60 mln worth of ETH from the project. The theft prompted an investigation by the SEC - which ruled DAO tokens were in fact securities and had to abide by federal laws.

What was hailed as a revolutionary fundraising project for Ethereum DApps all but ended there and then, not unlike LitePay.

Both projects were highly anticipated by the wider cryptocurrency community and their unceremonious endings gave a stark reminder of how difficult life is on the precipice of technological advancement.

While LitePay floats away into the ether, TenX have thrust to the fore and could well be the next champion for Litecoin support.

Theyve already launched LTC support on their Android and iOS platforms. Theyre also planning to launch a TenX/Litecoin card. Tried and tested, TenX could step up to the plate and do what Litepay couldnt - only time will show.

Meanwhile Litecoin trading launched on Korbit is a boon for the cryptocurrency. South Korea is a cryptocurrency trading hub, and the appetite for virtual currencies is still voracious. Finally garnering support in South Korea could have positive ramifications for LTC.

A third party may be joining the fray, as online crypto-friendly currency account service Wirex hinted on Twitter that Litecoin support is being developed.

What Is Cryptocurrency? – dummies

Part of Blockchain For Dummies Cheat Sheet

Cryptocurrencies, sometimes called virtual currencies, digital money/cash, or tokens, are not really like U.S. dollars or British pounds. They live online and are not backed by a government. Theyre backed by their respective networks. Technically speaking, cryptocurrencies are restricted entries in a database. Specific conditions must be met to change these entries. Created with cryptography, the entries are secured with math, not people.

Restricted entries are published into a database, but its a special type of database that is shared by a peer-to-peer network. For example, when you send some Bitcoin to your friend Cara, youre creating and sending a restricted entry into the Bitcoin network. The network makes sure that you havent not the same entry twice; it does this with no central server or authority. Following the same example, the network is making sure that you didnt try to send your friend Cara and your other friend Alice the same Bitcoin.

The peer-to-peer network solves the double-spend problem (you sending the same Bitcoin to two people) in most cases by having every peer have a complete record of the history of all the entries made within the network. The entire history gives the balance of every account including yours. The innovation of cryptocurrency is to achieve agreement on what the history is without a central server or authority.

Entries are the representation of cryptocurrency.

Cryptocurrencies are generated by the network in most cases to incentivize the peers, also known as nodes and miners, to work to secure the network and check entries. Each network has a unique way of generating them and distributing them to the peers.

Bitcoin, for example, rewards peers (known as miners on the Bitcoin network) for solving the next block. A block is a group or entries. The solving is finding a hash that connects the new block with the old one. This is where the term blockchain came from. The block is the group of entries, and the chain is the hash. Hashes are a type of cryptologic puzzle. Think of them as Sudoku puzzles that the peers compete to connect the blocks.

Every cryptocurrency is a little different, but most of them share these basic characteristics:

What Is Cryptocurrency? - dummies

Cryptocurrency Market Surges to $365 Billion, Start of a …

Throughout this week, as CCN reported, the cryptocurrency market has been eyeing a move towards the $350 billion region. Earlier today, on April 20, strong performances of major cryptocurrencies like bitcoin and Ethereum have led the valuation of the cryptocurrency market to surge to $365 billion.

Throughout 2018, amidst extreme volatility and recovery, investors inclined towards bitcoin as the safe haven asset. With the deepest liquidity and largest volume in the global market, bitcoin was able to sustain some stability while many cryptocurrencies recorded a free fall. Most assets declined by more than 80 percent from their all-time highs and struggled to record gains against bitcoin.

Over the past seven days, alternative cryptocurrencies (altcoins) and other major cryptocurrencies have consistently reported gains against the most dominant cryptocurrency in the market. The daily trading volume of the global cryptocurrency market crossed the $20 billion mark for the first time in April and the valuation of the market achieved a new monthly high.

In March and early April, investors were skeptical towards investing in cryptocurrencies other than bitcoin and Ethereum because they were uncertain about the short-term future of the cryptocurrency market. While altcoins tend to have intensified movements on the upside, it also has larger movements on the downside, and investors thought the risk was not worth taking.

Traders have started to take more risk than before by investing in cryptocurrencies like Ripple, Zilliqa, Nano, OmiseGo and others. As the volumes of altcoins across major exchanges surged, altcoins began to outperform bitcoin on a weekly basis, and it is possible that ERC20 tokens outperform major cryptocurrencies on a monthly basis by the end of April.

The next major target for the cryptocurrency market is the $400 billion mark and by surpassing that threshold, the cryptocurrency market would achieve a two-month high. At this juncture, it is safe to conclude that bitcoin has bottomed out at $6,000 and the market has begun a rapid recovery to its previous levels.

If the bitcoin price breaks the $9,500 level in the short-term, ideally within the next week, it is entirely possible that the cryptocurrency market surpasses $400 billion within April, in the next 10 days.

The Relative Strength Index (RSI) of bitcoin is in the 57 range and is signifying a neutral zone. Bitcoin is neither oversold or overbought based on current levels, as demonstrated by two momentum oscillators RSI and Williams Percent Range.

Both simple and exponential moving averages are indicating buy signals for bitcoin, as it continues to gain strong momentum. From this point, traders are expecting the bitcoin price to cross $8,500 and potentially make its way into the $9 billion region.

Non-ERC20 tokens like Ripple and Verge were the best performers on April 20, with solid 20 percent gains. Both Ripple and Verge have performed strong against bitcoin throughout April and they are continuing to build momentum against bitcoin and Ethereum.
