PERSON
David Chalmers
The philosopher who gave consciousness its hardest question—why physical processing gives rise to subjective experience at all—and whose zombie argument and explanatory gap now stand as the most precise instruments for assessing what AI can and cannot be.
There is a question that organizes the better part of a philosophical career, and it refuses to resolve. Why, when electrochemical signals traverse a hundred trillion synaptic connections, is there something it is like to be the system in which that processing occurs? David Chalmers articulated this as the
hard problem of consciousness in a 1994 conference paper that reshaped the field, distinguishing it from the “easy problems”—how the brain integrates information, discriminates stimuli, controls behavior—which are difficult in the ordinary scientific sense but tractable by the methods of cognitive science. The hard problem asks not what consciousness does but what consciousness is, and no amount of computational progress has brought us closer to answering it. Chalmers was born in Sydney in 1966, studied mathematics at the University of Adelaide on a Rhodes Scholarship before transitioning to philosophy at Indiana University under
Douglas Hofstadter, and now serves as University Professor of Philosophy and Neural Science at New
