Carl Hempel (1905–1997) was one of the 20th century’s great philosophers of science and a major proponent of logical empiricism. Born in Germany, he studied mathematics and logic at Göttingen with David Hilbert, before completing his PhD in philosophy at Berlin. In 1937 he emigrated to the United States to be Rudolf Carnap’s postdoctoral student at Chicago. Later he was professor of philosophy at Yale and then Princeton, before ending his career at the University of Pittsburgh. Hempel made canonical contributions to many central areas in philosophy of science, such as probability and confirmation theory, scientific explanation, induction, semantics, theory structure, and the logic of functional explanation in biology and the social sciences, some of which are reflected in the pieces collected here.
