William of Auvergne (c.1180–1249)

Active in Paris during the third and fourth decades of the thirteenth century, when universities were emerging as centres of Western European intellectual life, William played a decisive role in the early development of high medieval philosophy. His writing reveals a familiarity with Aristotle, all of whose major works except the Metaphysics were readily available in Latin translation, and with the Islamic philosophers, most especially Avicenna but also Averroes, whose commentaries on Aristotle were just beginning to circulate. William looked back to the Neoplatonic traditions of the twelfth century, but he also looked ahead to the late-thirteenth-century Aristotelianizing that he and his contemporary, Robert Grosseteste, did so much to promote.
