Abstract

The final twenty-five years of the thirteenth century have received relatively little treatment by historians of medieval philosophy. Yet this period, which spans roughly from the death of Thomas Aquinas to the arrival of Duns Scotus at Oxford, is characterized by a remarkable philosophical vitality. One of the more neglected figures of this period is James of Viterbo. A member of the Augustinian Order, James was a Master in the Theology faculty at Paris from 1293-1300. Making use of his recently edited Quodlibetal Questions and De divinis praedicamentis, the dissertation presents a historical reconstruction of James' metaphysics of finite being. Like most medieval thinkers, James is very concerned to distinguish between finite being and infinite being. While the divine being is absolutely simple, pure act, every finite being has within itself a composition of act and potency. This means that finite being has a structure that can be explicated by metaphysical analysis. There are three kinds of metaphysical composition found among finite beings: essence and existence; substance and accident; and matter and form. The dissertation analyzes James' understanding of these three compositions. Chapters I-III examine his position on issues involving essence and existence. Chapters IV and V deal with substance and accident. Chapters VI and VII are concerned with problems arising from the composition of matter and form. In presenting James' thought the dissertation gives some attention to determining his place in the doctrinal milieu of the late thirteenth century. James develops his own metaphysical positions only after deep reflection on the views of his contemporaries. He knows quite well the texts of Giles of Rome, Henry of Ghent, and Godfrey of Fontaines, and he is familiar with the work of Thomas Aquinas. Although he strives often to harmonize opposed positions, James possesses a highly personal metaphysics that cannot be reduced to that of other thinkers. The dissertation finds evidence for including James within the Neo-Augustinian movement of his day.
