 Upon returning to Paris, Abelard became scholar-in-residence at Notre Dame, a position he held until his romantic entanglement with Héloïse led to his castration, at which point he entered the Benedictine monastery of Saint Denis and Héloïse entered the convent of Argenteuil. After his recovery, Abelard resumed teaching at a nearby priory, primarily on theology and in particular on the Trinity. His method of philosophical analysis was seen as a direct challenge to more traditional approaches, and a synod, convened in Soissons to examine Abelard’s writings, condemned them and required Abelard to make a public avowal of faith, an experience he found humiliating; shortly afterwards he was allowed to settle in a wild and uninhabited section of land, to devote himself to contemplation.
