Peter Abelard, born near Nantes, rose to prominence as a teacher in Paris, arguing with William of Champeaux and later running his own schools. His affair and secret marriage to Heloise led to personal tragedy (his castration) and religious retirement. A proponent of conceptualism, Abelard applied dialectical reasoning to theology and provoked condemnation at the Council of Sens (1141). He died in 1142; his Historia Calamitatum and the Heloise letters remain key texts for medieval studies.

Life and career

Peter Abelard (1079-1142), born at Le Pallet near Nantes, was one of the most influential and controversial figures of twelfth-century scholasticism. He studied in Paris under Roscelin and William of Champeaux, and after a famous intellectual dispute with William he left to open his own school and later led the school at the Abbey of Saint-Genevieve.

He continued his studies at Laon under Anselm of Laon, then returned to Paris and is recorded as becoming a canon of Notre-Dame in 1115 . Abelard taught theology and attracted many students with his emphasis on reasoned argument and close textual analysis.

Heloise, scandal, and exile

Abelard's personal life became inseparable from his reputation. He entered an intense relationship with Heloise, the niece of Canon Fulbert; the couple had a son, Astrolabe, and later married in secret. When the relationship became public, Heloise was placed in the convent of Argenteuil and Fulbert arranged for Abelard to be attacked and castrated, an event usually dated to about 1117 1.

After his recovery Abelard entered monastic life at Saint-Denis while Heloise took the veil at Argenteuil. Abelard later founded the Paraclete, an oratory and then a monastery rebuilt in stone, where Heloise eventually served as abbess.

Theology, controversy, and later years

Abelard developed a theory of universals now described as conceptualism: universals exist in the mind as concepts that are predicated of individual things, a middle position between classical realism and late medieval nominalism. His theological method - applying dialectical reasoning to reconcile apparent contradictions in authorities - attracted both followers and critics.

In 1121 a provincial synod criticized his Introduction to Theology, and later his positions drew the public condemnation of Bernard of Clairvaux at the Council of Sens in 1141. Abelard appealed to Rome and set out to plead his case; illness forced him to stop at Cluny and he spent his final months under the care of Peter the Venerable. He died at the priory of Saint-Marcel near Chalon-sur-Saône in 1142.

Heloise lived on until 1164. In the modern era both their remains were reinterred together at Père-Lachaise Cemetery in Paris (moved there in 1817), and their tomb remains a noted site for visitors.

Writings and legacy

Abelard's autobiographical Historia Calamitatum and the letters exchanged with Heloise are primary sources for his life. His method helped shape the scholastic enterprise by insisting that reason and careful analysis be used alongside scriptural and patristic authority.

Modern scholarship continues to reassess Abelard's influence on medieval theology, ethics, and education; his letters also remain central to discussions of love, gender, and monastic life in the Middle Ages.
