This major publication is a history of the semantic tradition in philosophy from the early nineteenth century through its incarnation in the work of the Vienna Circle, the group of logical positivists that emerged in the years 1925–1935 in Vienna who were characterised by a strong commitment to empiricism, a high regard for science, and a conviction that modern logic is the primary tool of analytic philosophy. In the first part of the book, Alberto Coffa traces the roots of logical (...) positivism in a semantic tradition that arose in opposition to Kant's theory that a priori knowledge is based on pure intuition and the constitutive powers of the mind. In Part II, Coffa chronicles the development of this tradition by members and associates of the Vienna Circle. Much of Coffa's analysis draws on the unpublished notes and correspondence of many philosophers. The book, however, is not merely a history of the semantic tradition from Kant 'to the Vienna Station'. Coffa also critically reassesses the role of semantic notions in understanding the ground of a priori knowledge and its relation to empirical knowledge and questions the turn the tradition has taken since Vienna.

Philosophers often divide Carnap's work into syntactic, semantic, and later periods, but this disguises the importance of his early syntactical writing. In Logical Syntax Carnap is a thoroughgoing conventionalist and pragmatist. Once we see that, it is easier to see as well that these views were retained throughout the rest of his life, that the breaks between periods are not as important as the continuities, and that our understanding of such Carnapian notions as analyticity and probability needs reevaluation.
