CHAP. XXXIV scholastic method arrived at its highest constructive energy. In the Sentences one excerpted opinion was given and another possibly divergent, and at the end an adjustment was presented. This comparative formlessness attains in the Summa a serried syllogistic structure. Thomas, who finally perfects it, presents his connected and successive topics divided into quaestiones, which are subdivided into articuli, whose titles give the point to be discussed. He states first, and frequently in his own syllogistic terms, the successive negative arguments; and then the counter-proposition, which usually is a citation from Scripture or from Augustine. Then with clear logic he constructs the true positive conclusion in accordance with the authority which he has last adduced. He then refutes each of the adverse arguments in turn.

Thus the method of the Sentences is rendered dialectically organic; and with the perfecting of the form of quaestio and articulus, and the logical linking of successive topics, the whole composition, from a congeries, becomes a structure, organic likewise, a veritable Summa, and a Summa of a science which has unity and consistency. This science is sacra doctrina, theologia. Moreover, as compared with the Sentences, the contents of the Summa are enormously enlarged. For between the time of the Lombard and that of Thomas, there has come the whole of Aristotle, and what is more, the mastery of the whole of Aristotle, which Thomas incorporates in a complete and organic statement of the Christian scheme of salvation.
