It can be easy to think that all the good ideas have already been thought; after all, philosophy have been going on for more than 2500 years. But that isn't true! There are still some genius philosophers out there, of course. Here, we give you ten living people with ideas worth learning about.

Noam Chomsky

One of the most cited philosophers of the modern age, Chomsky has written extensively on linguistics, cognitive science, politics, and history. His work has had an effect on everything from developmental psychology to the debates between rationalism and empiricism, and led to a decline of support for behaviorism. He remains an active social critic and public intellectual, including here on Big Think.

Colorless green ideas sleep furiously

Slavoj Zizek

Zizek is a modern Marxist who has commented extensively on culture, society, theology, psychology, and our tendency to view the world through the lens of Ideology. He has devoted a great deal of time to updating the idea of Dialectic Materialism. He is also a frequent Big Think contributor.

Humanity is OK, but 99% of people are boring idiots.

Cornel West

Cornel is an American philosopher who focuses on politics, religion, race, and ethics. Hardly shy for the camera, West is often seen on television talk shows and even had a cameo in the Matrix films. His work has expanded on the ideas of W.E.B. Du Bois on more than one occasion, and continues to focus on the issues of being an Other in modern society. His Big Think videos can be found here.

The Enlightenment worldview held by Bu Bois is ultimately inadequate, and, in many ways, antiquated, for our time.

Martha Nussbaum

An American philosopher at the University of Chicago, Martha has written about subjects as diverse as ancient Greek philosophy, ethics, feminism, political philosophy, and animal rights. Along with Amartya Sen,she alsodeveloped the Capability Approach which inspired the United Nations Human Development Index.

Now the fact that Aristotle believes something does not make it true. (Though I have sometimes been accused of holding that position!)

Alasdair Macintyre

Alasdair Macintyre is a Scottish Philosopher who has written on ethics and morality, political philosophy, theology, and the history of philosophy. His most popular book, After Virtue, helped to fuel a resurgence in Virtue Ethics. His thought shifted from a Marxist view in his early work to one that combines his former Marxism with his new Catholicism and Neo-Aristotelian insights.

We are waiting not for Godot, but for anotherdoubtless very differentSt. Benedict.

Daniel Dennett

An American philosopher, cognitive scientist, and one of the so-called Four Horsemen of New Atheism. He has written on free will for decades, and supports the compatibilist view. He has also written on how philosophers think, explaining how the idea of the Intuition pump can both mislead and enlighten us. He also has very many interesting interviews with BigThink.

The Darwinian Revolution is both a scientific and a philosophical revolution, and neither revolution could have occurred without the other.

"A great scientific theory, like Newton's, opens up new areas of research... Because a theory presents a new way of looking at the world, it can lead us to ask new questions, and so to embark on new and fruitful lines of inquiry."

Peter Singer

A modern Consequentialist who puts his money where his ideas are. Author of The Life You Can Save, a book on how utilitarianism demands altruism from you right now, he went on to create an organization dedicated to the idea. He has also written on animal rights, and is a vegetarian. His stances on euthanasia and quality of life have been the cause of a great many protests over the years, often preventing him from speaking. His BigThink videos help explain his philosophy.

We are responsible not only for what we do but also for what we could have prevented.

Amartya Sen

An Indian Philosopher and Nobel Prize Laureate who was worked for decades in welfare economics, capability theory, and on the questions of justice. He often writes on the need to view the implementation of philosophical ideals in degrees of success, rather than as existent or non-existent. His work went on to inspire Martha Nussbaum, and they continue to compliment each others work.

Democracy has to be judged not just by the institutions that formally exist but by the extent to which different voices from diverse sections of the people can actually be heard

There is no gender identity behind the expressions of gender; that identity is performatively constituted by the very "expressions" that are said to be its results.
