Joseph M. de Torre, "Thomism and Postmodernism", in Postmodernism and Christian Philosophy, 248.
From the nominalism and voluntarism of William of Ockham (1300-1350), already adumbrated by the formalism of Duns Scotus (1266-1308), to the skepticism of Montaigne (1533-1592) and Francisco Sanchez (1522-1623), there was a logical development, aided by the so-called religious wars occasioned by Protestantism and, in the previous century, by the Hussite revolt in Bohemia as well as the lingering conflict with the Moslem Turks. The attention of philosophers was diverted to politics, economics and experimental sciences with the consequent weakening in metaphysical insights.
No footnotes or proof of any kind is offered. It is a rather hysterical tirade about how all Thomists before the 20th century were infected with Scotus' "formalism" and "essentialism" and how we must all return to the actus essendi to redeem the world. Oh well, what do you expect from a conference paper delivered at the top-secret invitation-only Maritain conferences at Notre Dame? I only post this as the best summary of the narrative of the decline of philosophy that began the instant someone first criticized Thomas Aquinas.
