. 1891–1970. German logical POSITIVIST, born in Ronsdorf, and a member of the Vienna Circle. He migrated to America where he worked mainly in Chicago and Los Angeles. He tried to show that METAPHYSICS arose through our confusing talk about the world with talk about language (cf. FORMAL MODE). He sought to apply his positivism to scientific method by his physicalism (see POSITIVISM), and later in an elaborate examination of CONFIRMATION and probability. Der logische Aufbau der Welt (The Logical Structure of the World), 1928.
