Abstract

Alan Richardson’s Carnap’s Construction of the World is a well-researched, richly-detailed, and highly instructive study of a crucial moment in the history of the analytic tradition: the transitional stage between the classical or early period dominated by Frege, Moore, and Russell, and the neo-classical or middle period dominated by Wittgenstein and the Vienna Circle. This stage marks a shift from ontic analysis to linguistic analysis; from platonism to conventionalism; from realistic metaphysics to anti-metaphysics; from rationalism to empiricism; and from logicism to logical positivism. Only the firm commitments to antipsychologism, to “logic as the essence of philosophy,” and to semantics remain the same. But above all it is the moment at which the positive influence of Kant upon analytic philosophy—in the form of a vestigial neo-Kantianism—is finally extinguished. All this and more is packed into Rudolf Carnap’s 1928 treatise Der logische Aufbau der Welt ; hence Richardson aptly concentrates his account by unpacking the philosophical content, context, and consequences of the Aufbau.
