American philosopher and cognitive scientist who tied questions about the mind, consciousness, free will and evolution tightly to science. He studied with ordinary-language philosopher Gilbert Ryle at Oxford and taught at Tufts for nearly half a century.

He argued consciousness is the product of many parallel brain processes, with no central "Cartesian theater" where it all comes together. On free will, he held that the freedom compatible with determinism is all the freedom worth wanting. As one of the "New Atheists," he also had a big public profile.

Big ideas

Consciousness as a user illusionConsciousness is like a simplified interface the brain shows itself. There are no inexplicable "qualia."
The intentional stanceIf treating a system as an agent with beliefs and desires predicts it well, then in that sense it has beliefs.
Freedom worth wantingEven under determinism, the abilities to deliberate, respond to reasons and improve yourself are real — and that's the freedom worth wanting.

If you think like them…

If you're like Dennett, you trust the scientific picture of the world but don't give up on human freedom and responsibility. You'd rather treat consciousness as something explainable than leave it a mystery, and you're willing to question even gut intuitions about "what red feels like." You also lean toward thinking memory and personality carrying on is what makes you the same person.
