Logic and Propositional Calculus

Abstract

Propositional logic was eventually refined using symbolic logic. The 17th/18th century philosopher Gottfried Leibniz (an inventor of calculus) has been credited with being the founder of symbolic logic. Although his work was the first of its kind, it was unknown to the larger logical community. Consequently, many of the advances achieved by Leibniz were re-achieved by logicians like George Boole and Augustus De Morgan in the 19th century completely independent of Leibniz.
