Abstract

The article is an overview of the main philosophical ideas of Gottlob Frege. The author stresses that Frege has built important tools for the analysis of language: the logic of sentences and the logic of predicates. He stresses also the importance of Frege’s work on the foundations of mathematics. He argues that his greatest achievement is the fact that thanks to Frege language has become main object of investigations in contemporary philosophy, and that theory of meaning has replaced the traditional theory of knowledge. Frege’s ideas, taken together, constitute a well-defined method, a particular style of approach to philosophical problems and of their resolution. The effectiveness and enduring pertinence of Frege’s method is demonstrated by means of an analysis of several typical category mistakes, frequent in philosophical argumentation.
