"In his controversial writings William of Ockham appears as the advocate of secular absolutism. He denies the right of the popes to exercise temporal power, or to interfere in any way whatever in the affairs of the Empire. ... In philosophy William advocated a reform of Scholasticism both in method and in content. The aim of this reformation movement in general was simplification. This aim he formulated in the celebrated "Law of Parsimony", commonly called "Ockham's Razor": "Entia non sunt multiplicanda sine necessitate". With this tendency towards simplification was united a very marked tendency towards skepticism a distrust, namely, of the ability of the human mind to reach certitude in the most important problems of philosophy. ... Ockham's attitude towards the established order in the Church and towards the recognized system of philosophy in the academic world of his day was one of protest. He has, indeed, been called "the first Protestant". Nevertheless, he recognized in his polemical writings the authority of the Church in spiritual matters, and did not diminish that authority in any respect. Similarly, although he rejected the rational demonstration of several truths which are fundamental in the Christian system of theology, he held firmly to the same truths as matters of faith."
