This volume investigates the ontological status of universals and their relationship to particular entities within the framework of late medieval scholastic realism. John Wyclif, a prominent 14th-century philosopher and theologian, constructs a rigorous defense of realism, arguing that universals possess a real existence independent of the human mind. The text utilizes Aristotelian logic and metaphysical inquiry to challenge nominalist interpretations of reality, providing a systematic account of how individual objects participate in universal forms. This edition, translated and edited by Sir Anthony Kenny, contextualizes Wyclif's complex Latin arguments for a modern philosophical audience.

Scholars and historians of philosophy recognize this edition as a significant contribution to the study of Wyclif's metaphysical system. Readers frequently note the academic density of the prose, which requires a strong background in scholastic terminology to fully navigate the author's arguments.
