Abstract

The excess of confidence in logic culminates in logicism, a position common to medieval Scholasticism and modern rationalism. This mistake can best be illustrated by the idea, especially developed by Leibniz, that the lack of contradiction in a concept is a warrant that the corresponding object exists. Certain inconsistencies in Leibniz's system were corrected by Wolff, whose excesses finally allowed Kant to uncover the logicist fallacy.
