Sir Karl Raimund Popper, CH, MA, Ph.D., D.LITT, FBA, FRS (July 28, 1902 - September 17, 1994)
According to Wikipedia, Popper "was an Austrian-born British philosopher and a professor at the London School of Economics. He is counted among the most influential philosophers of science of the 20th century, and also wrote extensively on social and political philosophy. Popper is perhaps best known for repudiating the classical observationalist-inductivist account of scientific method by advancing empirical falsifiability as the criterion for distinguishing scientific theory from non-science; and for his vigorous defense of liberal democracy and the principles of social criticism which he took to make the flourishing of the 'open society' possible....
"Popper was a member of the Academy of Humanism and described himself as an agnostic..."
Today is also the birthday of German philosopher and anthropologist, Ludwig Andreas von Feuerbach (July 28, 1804 - September 13, 1872), who believed that "God is nothing else than man: he is, so to speak, the outward projection of man's inward nature."
