Oliver L. Reiser

Oliver Leslie Reiser (November 15, 1895 - June 6, 1974) was an American philosopher, active as a professor at Ohio State University and at the University of Pittsburgh, serving as head of the philosophy department at the latter. Reiser notably proposed the concept of the psychosphere, a field encompassing the planet Earth that he supposed acts as a living memory storage system and influences biological evolution of lifeforms within it, on which basis he advocated for radio-eugenics, a means whereby the psychosphere would be manipulated technologically to promote preferred evolutionary pressures.
