## Frege, Gottlob

(gôt`lōp frā`gə), 1848–1925, German philosopher and mathematician. He was professor of mathematics (1879–1918) at the Univ. of Jena. Frege was one of the founders of modern symbolic logic**symbolic logic**

formalized system of deductive logic, employing abstract symbols for the various aspects of natural language. Symbolic logic draws on the concepts and techniques of mathematics, notably set theory, and in turn has contributed to

He considered verbal concepts to be expressible as symbolic functions with one or more variables. His books include

*Die Grundlagen der Arithmetik*(1884; tr.

*The Foundations of Arithmetic,*1950);

*Grundgesetze der Arithmetik*(2 vol., 1893–1903).

Born Nov. 8, 1848, in Wismar; died July 26, 1925, in Bad Kleinen. German logician.

Frege received his Ph.D. from the University of Göttingen in 1873. He was a professor at the University of Jena from 1879 to 1918. Frege’s principal work was *The Fundamental Laws of Arithmetic* (vols. 1–2, 1893–1903), in which he proposed a system of formalized arithmetic based on a second-order predicate calculus that he developed. His intention was to provide a substantiation of the notion of the reducibility of mathematics to logic (*see*LOGICISM).
