A longtime member of the philosophy faculty at Tufts University, Professor Dennett was best-known within philosophy for his work in philosophy of mind and on free will, although outside philosophy he was famous as one of the "New Atheists" and as a champion of evolutionary explanations. Comments are open for remembrances from those who knew Professor Dennett or for those who wish to comment on the significance of his work.
