As a leading member of the Vienna Circle, Carnap's aim was to bring about a 'unified science' by applying a method of logical analysis to the empirical data of all the sciences. The work shows the strong influence of Wittgenstein, Russell and Frege. This, the first English translation, was revised by Carnap for this edition.
Rudolf Carnap, a German-born philosopher and naturalized U.S. citizen, was a leading exponent of logical positivism and was one of the major philosophers of the twentieth century. He made significant contributions to philosophy of science, philosophy of language, the theory of probability, inductive logic and modal logic. He rejected metaphysics as meaningless because metaphysical statements cannot be proved or disproved by experience. He asserted that many philosophical problems are indeed pseudo-problems, the outcome of a misuse of language.
Even though he might have been wrong on some (possibly a lot) of issues, Carnap and his general attitude towards philosophy still holds a special place in my heart.
makes the claim that metaphysical statements are just pseudo-problems that get mixed up w/ traps in language and then proceeds to write about a universal language of science.
