First printing of Carnap's important work modality and semantics, in which he, as the first logician ever, uses semantics to explain modalities. This led to an interest in the structure of scientific theories, and his main concerns here were to describe the distinction between analytic and synthetic statements and to suitably formulate the verifiability principle; -he thus wishes to find a criterion of significance that can be applied to scientific language.
