Daniel Clement Dennett III (born March 28, 1942) is an American philosopher, writer, and cognitive scientist whose research centers on the philosophy of mind, philosophy of science, and philosophy of biology, particularly as those fields relate to evolutionary biology and cognitive science.
As of 2017 he is the co-director of the Center for Cognitive Studies and the Austin B. Fletcher Professor of Philosophy at Tufts University. Dennett is an atheist and secularist, a member of the Secular Coalition for America advisory board, and a member of the Committee for Skeptical Inquiry, as well as an outspoken supporter of the Brights movement. Dennett is referred to as one of the "Four Horsemen of New Atheism", along with Richard Dawkins, Sam Harris, and the late Christopher Hitchens.
Dennett is a member of the editorial board for The Rutherford Journal.
Dennett was born on March 28, 1942 in Boston, Massachusetts, the son of Ruth Marjorie (née Leck) and Daniel Clement Dennett, Jr. Dennett spent part of his childhood in Lebanon, where, during World War II, his father was a covert counter-intelligence agent with the Office of Strategic Services posing as a cultural attaché to the American Embassy in Beirut. When he was five, his mother took him back to Massachusetts after his father died in an unexplained plane crash. Dennett's sister is the investigative journalist Charlotte Dennett. Dennett says that he was first introduced to the notion of philosophy while attending summer camp at age 11, when a camp counselor said to him, "You know what you are, Daniel? You're a philosopher."
Dennett graduated from Phillips Exeter Academy in 1959, and spent one year at Wesleyan University before receiving his Bachelor of Arts in philosophy at Harvard University in 1963. At Harvard University he was a student of W. V. Quine. In 1965, he received his Doctor of Philosophy in philosophy at the University of Oxford, where he studied under Gilbert Ryle and was a member of Hertford College.
Dennett describes himself as "an autodidact—or, more properly, the beneficiary of hundreds of hours of informal tutorials on all the fields that interest me, from some of the world's leading scientists".
He is the recipient of a Fulbright Fellowship, two Guggenheim Fellowships, and a Fellowship at the Center for Advanced Study in the Behavioral Sciences. He is a Fellow of the Committee for Skeptical Inquiry and a Humanist Laureate of the International Academy of Humanism. He was named 2004 Humanist of the Year by the American Humanist Association.
In February 2010, he was named to the Freedom From Religion Foundation's Honorary Board of distinguished achievers.
In 2012, he was awarded the Erasmus Prize, an annual award for a person who has made an exceptional contribution to European culture, society or social science, "for his ability to translate the cultural significance of science and technology to a broad audience."
