Transhumanism ... The contemporary meaning of the term transhumanism was foreshadowed by one of the first professors of futurology, FM-2030, who taught "new concepts of the Human" at The New School of New York City in the 1960s, when he began to identify people who adopt technologies, lifestyles and world views transitional to "posthumanity" as "transhuman". This hypothesis would lay the intellectual groundwork for the British philosopher Max More to begin articulating the principles of transhumanism as a futurist philosophy in 1990, and organizing in California an intelligentsia that has since grown into the worldwide transhumanist movement...
