Robert Grosseteste Quotes on Knowledge
Robert Grosseteste (c. 1175–1253), the bishop of Lincoln and first chancellor of the University of Oxford, gave thirteenth-century Latin philosophy one of its most influential epistemological syntheses through the commentary on Aristotle's Posterior Analytics and the long sequence of scientific opuscula. The framework articulates the method of resolution and composition — the philosopher decomposes the observed phenomenon into its principles and then reconstructs the phenomenon from those principles by demonstrative deduction — that the subsequent scholastic tradition would identify as the proper procedure of natural science, and Grosseteste's institutional and intellectual influence shaped the early Oxford tradition of natural philosophy that Roger Bacon and the later Mertonian calculators would carry forward.
