The Unity of Science

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. Based on the belief that statements are meaningful only if they are empirically verifiable, Carnap endeavours to work out a way in which observation statements required for verification are not private to the observer. The work shows the influence of Wittgenstein, Russel and Frege.
