'Central to this end were Frege's insights on quantification, the notation that expressed it, the logicist project, and the extension of mathematical notions like function and argument to natural language. The long-awaited Cambridge Companion to Frege is a compendium of Fregean scholarship that rigorously explores these and similar topics; editors Thomas Ricketts and Michael Potter have compiled a comprehensive collection of fourteen essays that individually provide focused appraisals of a number of Frege's most substantial insights.' Alexander Bozzo, University of Milwaukee 'The long-awaited publication of The Cambridge Companion to Frege is a major event in Frege scholarship … Every serious reader of Frege should read it.'
