description William of Ockham Overview

William of Ockham (c. 1287–1347) was an influential medieval English Franciscan friar and philosopher. He developed nominalism, a philosophical stance arguing that universals—abstract concepts like “humanity”—lack independent existence. His emphasis on parsimony in reasoning, now known as Ockham’s razor, advocates for selecting the simplest explanation when considering competing hypotheses.

This work remains significant for scholars studying logic, epistemology, and medieval philosophy particularly those interested in debates about abstract thought and justification of belief.
