which reduced the Trinity to three aspects or attributes of the Divine Being--power, wisdom, and love. "A doctrine is to be believed," he held, "not because God has said it, but because we are convinced by reason that it is so." His whole attitude was that of the free, if reverent, enquirer. "By doubt," he says, "we come to enquiry; by enquiry we reach the truth." His book _Sic et Non_, a collection of conflicting opinions of the Christian Fathers on the chief tenets of the faith, was to be the first step towards arriving at the truth. [Sidenote: Mysticism.] He was condemned twice--his doctrine of the Trinity at Soissons in 1121, his whole position at Sens in 1141. The leaders of orthodoxy met him not with argument but with a demand for recantation. St. Norbert during the early part of his life, and St. Bernard both early and late, pursued him with their enmity. Their objection was not to his particular views, but to his whole attitude towards divine revelation; and the conclusions in which the use of the scholastic method landed its advocates perhaps justified the rigid theologians in the general distrust of the exercise of reason on such subjects. St. Bernard did not hesitate to attack even Gilbert de la Porrée, Bishop of Poictiers, an avowed Realist, who attempted to explain the Trinity. In fact, St. Bernard represents the reaction from Scholasticism, which took the form of Mysticism, that is, the purely contemplative attitude towards the verities of the Christian creed. In this he was followed with much greater extravagance by the school which found its home in the great abbey of St. Victor--Hugh (1097-1143), who formulated the sentence "Knowledge is belief, and belief is love," and Richard (died in 1173), who applied to the intuitive perception of spiritual things and to the love of them the same dialectical and metaphysical methods as the Schoolmen applied to reason. [Sidenote: After Abailard.] The results of Abailard's work are seen in two directions. His _Sic et Non_ became the foundation of the work of the "Summists," who, in the place of Abailard's purely critical work, occupied themselves in systematising authorities with a view to the reconciliation of their conflicting opinions. The greatest of these was Peter the Lombard (died 1160), who became Bishop of Paris, and whose _Sententiae_ was taken as the accredited text-book of theology for the next three hundred years. With the Summists theology returned to its attitude of unquestioning obedience to the conclusions of the early Fathers. But in the second place, Abailard was indirectly responsible for "the troubling of the Realistic waters," which resulted in many modifications of the original position. [Sidenote: Classical revival.]
