(rŏs`əlĭn), c.1045–c.1120, French scholastic philosopher, also called Roscellinus, Johannes Roscellinus, and Jean Roscelin. Roscelin was one of the first thinkers of the Middle Ages to deal with the problem of universals, or general concepts (see realismrealism,

). Although very little of his writing has survived, he seems to have been an extreme nominalist, teaching that universals were nothing more than words. Roscelin's position was attacked by his pupil, Peter AbelardAbelard, Peter

, but Abelard's own viewpoint on this question showed a considerable debt to Roscelin. Accused of the heresy of tritheism (teaching that the Three Persons of the Trinity are separate individuals), Roscelin was ordered (1092) by the Synod of Soissons to recant, but he escaped condemnation.

Born circa 1050 in Compiègne; died circa 1120. French medieval philosopher and theologian; representative of extreme nominalism.

Roscelin taught liberal arts in Compiégne and later, in Loches, where his pupils included Abélard. After 1092 he was a canon at the cathedral of Besançon. Only one of his works has survived—a rhetorical pamphlet containing an invective against Abélard (in J. P. Migne, Patrología, Latin series, vol. 178). There is information about Roscelin in polemical works by Anselm of Canterbury, Abélard, and John of Salisbury, as well as in the anonymous tract De generibus et speciebus (Of Categories and Species).

Roscelin formulated the nominalist thesis that substances are the only real things. Regarding sensory impressions as the point of departure for understanding the external world, he viewed general concepts and categories (universalia) as merely names or even as the “breathing of a word” (flatus vocis). He defended the applicability of the dialectic, defined as the art of logical reasoning, to theological questions.

Roscelin asserted that the reality of each of the three persons in the divine trinity presupposes their separate existence as individual substances—a view regarded by orthodox theologians as the heresy of tritheism. This doctrine was condemned by the church Council of Soissons (1092). Roscelin contributed to the development of the doctrine of “double truth.”

Church officials threatened Jean Roscelin, one of Abelard's teachers and a leading 12th-century philosopher, with excommunication if he did not recant one of his theories; he recanted.
Yet another factor conniving at the segregation of natural philosophy and theology is certainly to be linked to the arising trends of nominalism (or vocalism), represented foremost by Roscelin of Compiegne and Petrus Abelard (see Schulthess and Imbach 1996:101ff.; Stiefel 1985:61; King 2004); paving a way indirectly to the via moderna of William of Ockham the nominalism played a strategic role in curbing the compass of symbolism prompted by the previous ages.

The Trinity was an even more sensitive topic, and it was for their efforts to establish this doctrine on a rational footing that Roscelin, William of Conches, Gilbert of Poitiers, and, most famously, Peter Abelard incurred the wrath of monastic conservatives like Anselm of Canterbury and Bernard of Clairvaux.
Relying on primary texts, provided at length in the Latin, as well a stupendous collection of secondary literature, Marenbon traces Abelard's life from his earliest studies with Roscelin and William of Champeaux to his appearances before the Councils of Soissons (1121) and Sens (1140) to his death outside Cluny in 1142.
