The term "transhumanism" was coined by Aldous Huxley's brother, the evolutionary biologist and First Director-General of UNESCO, Julian Huxley (1887–1975):
Julian Huxley and Transhumanism
"I believe in transhumanism: once there are enough people who can truly say that, the human species will be on the threshold of a new kind of existence, as different from ours as ours is from that of Peking man. It will at last be consciously fulfilling its real destiny."Transhumanism (aka "H+") in the modern sense of the term dates to the pioneering work of Max More and his colleagues at the Extropy institute.
("Transhumanism." Julian Huxley.
In New Bottles for New Wine, pp 13-17.
London: Chatto & Windus, 1957).
A contemporary statement of the transhumanist perspective is set out in The Transhumanist Declaration of the World Transhumanist Association (WTA).
