"This volume is a introduction to the thought of Gottlob Frege, one of the most influential philosophers of the twentieth century." "The chapters follow Frege's thought in chronological sequence, from the nature of logic, proof and language in Concept Scripts I and II, to The Foundations of Arithmetic, The Basic Laws of Arithmetic, and, finally, Logical Investigations." "Written by Anthony Kenny, leading figure in contemporary philosophy, this volume guides the reader through an accessible explanation and assessment of Frege's radical and lasting contributions to our understanding of language, meaning, and the foundations of arithmetic."--BOOK JACKET.
