- Popper, Sir Karl Raimund
-
▪ 1995Austrian-born British philosopher (b. July 28, 1902, Vienna, Austria-Hungary—d. Sept. 17, 1994, Croydon, Surrey, England), believed that knowledge—particularly scientific knowledge—evolves from individual experience and cannot be verified through inductive reasoning. Popper postulated that since no one can ever observe and verify all possible evidence to prove a scientific hypothesis correct, it is necessary only to discover one observed exception to the hypothesis to prove it false. He rejected as "pseudoscience" any system of beliefs that could not pass this "falsifiability criterion" and that relied on predetermined "laws" of human behaviour. These included logical positivism, metaphysics, Marxism, fascism, and Freudian psychoanalysis. In the 1980s many conservative politicians seized on his contention that government should avoid evil rather than seek social reform by actively pursuing good. Popper was educated at the University of Vienna (Ph.D., 1928) and worked for a time under the psychiatrist Alfred Adler. He first presented his theories in the highly regarded Logik der Forschung (1934; The Logic of Scientific Discovery, 1959). Three years later he immigrated to New Zealand, where he taught philosophy at Canterbury University College, Christchurch, until he accepted a post at the London School of Economics (1945). Popper formally retired in 1969, but he continued to write and lecture in England, the U.S., Australia, and New Zealand. His other principal books include The Open Society and Its Enemies (1945), The Poverty of Historicism (1957), Unended Quest: An Intellectual Autobiography (1976), and A World of Propensities (1990). Popper was knighted in 1965, elected a fellow of the Royal Society in 1976, and made a Companion of Honour in 1982.
