An adventurer in his youth, he went on to study medicine, practice psychiatry in Ontario, and befriend a number of noted men of letters in Canada, the U.S., and England. In addition to writing and delivering professional papers, Bucke wrote three book-length Man's Moral Nature, Walt Whitman, and – his best known work – Cosmic Consciousness, a classic in the modern study of mystical experience.
