Canadian philosopher and a leading figure of "neurophilosophy," which put neuroscience at the center of philosophy. He works at UC San Diego with his wife Patricia Churchland — together they're known as "the Churchlands."

In a 1981 paper he proposed "eliminative materialism": everyday psychological concepts like belief and desire belong to a false theory that mature neuroscience will replace. Just as "phlogiston" disappeared from science, one day "belief" might too.

Big ideas

Eliminative materialismFolk psychology — explaining behavior with beliefs and desires — is a false theory that neuroscience will replace.
The mind as a neural networkCognition isn't manipulating sentence-like representations; it's patterns of activation in neuron populations — transformations in high-dimensional vector spaces.
Qualia are brain states too"What red feels like" is ultimately a particular activation pattern in the visual cortex, and science will come to see it that way.

If you think like them…

If you're like Churchland, you're a science optimist who believes everything about the mind will eventually be explained by the brain. You're ready to drop even familiar everyday concepts if science says they're wrong. You also tend to see morality as a social skill the brain learns rather than a transcendent fact.
