 Johannes Sharpe (ca. 1360–after 1415) is the most important and original author among the so called “Oxford Realists”, a group of thinkers influenced by John Wyclif’s logic and ontology. His semantic and metaphysical theories are the culmination of the main preceding traditions of thought, since he developed the new form of realism begun by Wyclif, on the one hand, but was open to many nominalist criticisms of the traditional realist strategies, on the other.
