Karl Popper

Sir Karl Raimund Popper (July 28, 1902 – September 17, 1994), was an Austrian-born British philosopher of science and 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 science; for advancing empirical falsifiability as the criterion for distinguishing scientific theory from non-science; and for his defense of liberal democracy and the principles of social criticism which he took to make the flourishing of the "open society" possible.
