This work investigates the fundamental epistemological question of the early 16th century: what constitutes knowledge? Alexander Broadie, an expert in Scottish and medieval philosophy, examines the intellectual climate at the University of Paris between 1500 and 1530. By analyzing the doctrines of philosophers such as John Mair and George Lokert, Broadie reconstructs the framework of sensory and intellectual cognition that defined the traditionalist response to emerging reformist thought.

Scholars recognize this text as a foundational study for understanding the specific philosophical traditions that preceded the Reformation. Readers frequently note the academic density of the prose, which provides a rigorous look at scholastic debates that are often overlooked in broader historical surveys.
