H. P. Grice, "Carnap"

CARNAPIANUM IMPLICATUM -- Carnap, Rudolf (1891–1970) German-American philosopher, a leading member of the Vienna Circle, born in Ronsdorf, Germany and emigrated to the United States in 1935, where he taught at University of Chicago and UCLA. Influenced by Frege and Wittgenstein, Carnap held that metaphysical problems are pseudo-problems and that philosophy should proceed by applying the methods of modern logic and mathematics. The analysis of syntax is especially significant in solving philosophical disputes, and Carnap also sought philosophical clarification by distinguishing between the material questions about the world and formal questions about our framework of concepts. In his long and productive career, he made many influential contributions on topics such as logical syntax, perception, the philosophy of science, the theory of meaning, the foundations of mathematics, formal semantics, the foundations of modal logic, physicalism, probability and confirmation, induction and the unity of science. With Reichenbach, he founded the journal Erkenntnis, and edited the International Encyclopedia of Unified Science with Neurath and Morris. His major works include The Logical Construction of the World (1928), The Logical Syntax of Language (1934), Meaning and Necessity (1947), and The Logical Foundations of Probability (1950).
