A prominent member of the Huxley family, he was the author of nearly fifty books, producing novels such as Brave New World (1931), set in a dystopian future; non-fiction works such as The Doors of Perception (1954), interpreting his psychedelic experience with mescaline; and wide-ranging essays of social and literary criticism.

One-third, more or less, of all the sorrow . . . [we] must endure is . . . inherent in the human condition, the price we must pay for being sentient and self-conscious organisms, aspirants to liberation, but subject to the laws of nature and under orders to keep on marching, through irreversible time . . . toward decrepitude and the certainty of death. The remaining two-thirds of all sorrow is homemade and, so far as the universe is concerned, unnecessary.
