Popper, Sir Karl Raimund, 1902–94, Anglo-Austrian philosopher, b. Vienna. He became familiar with the Vienna circle of logical positivists (see logical positivism logical positivism, also known as logical or scientific empiricism, modern school of philosophy that attempted to introduce the methodology and precision of mathematics and the natural sciences into the field of philosophy.

He taught at Canterbury Univ., New Zealand (1937–45), and then at the London School of Economics, retiring in 1969. Popper's thought develops from his view of knowing as an individual, unpredictable act of genius, not acquired by induction, as empiricists hold, nor limited to verifiable statements, as the logical positivists hold. Like the logical positivists, Popper worked with the distinction between scientific knowledge and pseudoscience, but he understood the two to be related as well as distinct: pseudoscience or "myth," as he sometimes termed it, can inspire or grow into science, or overlap with it (as in the case of psychology psychology, science or study of the thought processes and behavior of humans and other animals in their interaction with the environment.

Popper also questioned historicism (the doctrine that there are general laws of history) because history, as he saw it, is influenced by the growth of knowledge, and, since knowing is a matter of unpredictable insight, neither the growth of knowledge nor its historical consequences can be systematized. In the political arena he was perhaps best known for his contention, set forth in The Open Society and Its Enemies (1945), that communism communism, fundamentally, a system of social organization in which property (especially real property and the means of production) is held in common.
