Sir Karl. 1902–94, British philosopher, born in Vienna. In The Logic of Scientific Discovery (1934), he proposes that knowledge cannot be absolutely confirmed, but rather that science progresses by the experimental refutation of the current theory and its consequent replacement by a new theory, equally provisional but covering more of the known data. The Open Society and its Enemies (1945) is a critique of dogmatic political philosophies, such as Marxism. Other works are The Poverty of Historicism (1957), Conjectures and Refutations (1963), and Objective Knowledge (1972)
