Daniel Dennett 1942 – 2024

Daniel Clement Dennett was an American philosopher of mind, philosopher of biology, and longtime professor at Tufts University. A pupil of Gilbert Ryle, he developed an influential functionalist account of mental phenomena, defended a compatibilist conception of free will, and became a leading philosophical interpreter of evolutionary biology and cognitive science. Consciousness Explained, Darwin's Dangerous Idea, Freedom Evolves, and From Bacteria to Bach and Back set out his vision of mind and meaning as the products of a long natural history. He was also one of the most prominent public defenders of secular naturalism in the early twenty-first century.

Daniel Clement Dennett III was born in Boston in March 1942, the son of a historian and OSS officer who died in a plane crash in Ethiopia in 1947. He took his bachelor's at Harvard in 1963, where he wrote a senior thesis under W. V. O. Quine, and his doctorate at Christ Church, Oxford, in 1965 under Gilbert Ryle. After a few years at the University of California, Irvine, he moved in 1971 to Tufts, where he was Austin B. Fletcher Professor of Philosophy and co-director of the Center for Cognitive Studies for the rest of his career.

His major books include Content and Consciousness (1969), Brainstorms (1978), Elbow Room (1984), The Intentional Stance (1987), Consciousness Explained (1991), Darwin's Dangerous Idea (1995), Freedom Evolves (2003), Breaking the Spell (2006), Intuition Pumps and Other Tools for Thinking (2013), From Bacteria to Bach and Back (2017), and the memoir I've Been Thinking (2023). He was widely credited as one of the 'Four Horsemen of the New Atheism' alongside Dawkins, Harris, and Hitchens.

Dennett defended a thoroughgoing naturalism in which consciousness, intentionality, free will, and religion are all to be explained as the products of evolutionary and cultural processes rather than as irreducible features of the world. His 'intentional stance', the multiple drafts model of consciousness, the heterophenomenological method, and the treatment of evolution as a substrate-neutral algorithm shaped philosophy of mind and cognitive science for half a century. He died in Portland, Maine, in April 2024.
