William of Ockham is known for his “razor,” for his logic, and for his nominalistic and empirical viewpoint. Living in the fourteenth century, he was the dominant figure in the movement away from Albertus Magnus, Thomas Aquinas, and John Duns Scotus, the great system builders of the thirteenth century. He was the inspirer of an empirically and nominalistically inclined movement that contended with the Thomistic, Albertist, Scotist, and Averroistic schools of the next several centuries. However, Ockham was not a skeptic. He undermined and rejected most of the metaphysics and a good deal of the natural theology of his contemporaries, but he was a theologian who accepted the traditional Christian dogmas on faith and who preferred to accept them on faith alone rather than to argue for them on dubious philosophic grounds.
