Volume one of this two-volume set contains contributions by Gottleb Frege and Wilfrid Sellars and topics covered include "the structure and content of truth", "conceptual role semantics" and "linguistics and psychology". Volume two contains essays by W.V.W. Quine and Christopher Peacocke, and subjects covered include "belief and the basis of meaning", "the refutation of conventionalism" and "the metaphysics of concepts".
