Rudolf Carnap 1891 – 1970

Rudolf Carnap was a German-born philosopher and a leading figure of the Vienna Circle and of logical empiricism. His Logical Structure of the World attempted to construct all scientific concepts from elementary experiences using the logic of Russell and Whitehead, while his Logical Syntax of Language proposed that philosophical questions are best understood as questions about the syntax of scientific languages. After emigrating to the United States in 1935, he developed an inductive logic of confirmation and a tolerant pluralism about formal frameworks. His work shaped the course of twentieth-century philosophy of science.
