Nominalist application of French theologian, philosopher, and composer Peter Abelard or Pierre Abélard of the principles of ancient Greek logic to the doctrines of the medieval Catholic Church led to charges of heresy; after his pupil Héloise, his pupil and the object of his lust affair, bore him a child, he secretly married her, whose angered family castrated him, after which he served as a monk.

The equally famous preeminent and perhaps the greatest of the Middle Ages during his life as a poet perhaps also ranked of his day, his ideas earned more converts and less condemnation. In all areas, brilliant, innovative, and controversial Abélard, a genius, knew and made no apologies. His vast knowledge, wit, charm, and even arrogance drew a generation of finest minds of Europe to Paris to learn.
