A theological Platonist, Abelard emphasized Aristotle's dialectic method. His belief that the methods of logic could be applied to the truths of faith was in opposition to the mysticism of St. Bernard. He also opposed the extreme views of William of Champeaux and Roscelin on the problems of universals. His own solution, in which universals are considered as entities existent only in thought but with a basis in particulars, is called moderate realism and to some extent anticipates the conceptualism of St. Thomas Aquinas.
His most influential work was Sic et non, a collection of contradictory selections from Scripture and the Fathers of the Church. In his introduction to Sic et non, Abelard set a method of resolving these apparent contradictions, thereby making the work significant for the development of the scholastic method. This work formed the basis for the widely read Sentences of Peter Lombard, who may have been Abelard's pupil. Abelard was perhaps most important as a teacher; among his pupils were some of the celebrated men of the 12th cent., including John of Salisbury and Arnold of Brescia. Of Abelard's poetry only Latin hymns survive.
