The medieval intellectual tradition that combined classical philosophy with Christian theology through rigorous logical analysis, organized around the new universities of Paris, Oxford and Bologna between the twelfth and fifteenth centuries.
Scholasticism is best understood as a method before a doctrine. Teaching proceeded by lectio, commentary on an authoritative text, and by quaestio and disputatio — the formal posing of a question, the marshalling of the strongest arguments on the wrong side, and only then the author's resolution and his replies to each objection in turn. Abelard's Sic et Non had set the pattern by assembling contradictory authorities and refusing to resolve them, forcing readers to reason rather than cite. The recovery of Aristotle's full corpus, reaching the Latin West largely through Arabic transmission and the commentaries of Avicenna and Averroes, gave the method something formidable to work on.
Aquinas is the figure whose work defined what scholasticism came to mean, and the architecture of the Summa — objections, then the contrary authority, then his own answer, then a reply to every objection — is the method in its mature form. Duns Scotus and William of Ockham pushed in other directions, and the long dispute over universals between realists and nominalists set problems that analytic metaphysics still works on.
The movement was displaced by Renaissance humanism, whose scholars mocked its Latin and its preoccupations; the jibe about angels dancing on a pinhead is a later invention rather than a real scholastic question, which is itself a fair indication of how the caricature has outlived the substance. Its second life came through the School of Salamanca, and its deepest legacy is structural: the requirement to state your opponent's case at full strength before answering it is a scholastic invention that Western academic argument never abandoned.
