The Start of Metaphysics

THE START OF METAPHYSICS* THEODORE J. KoNDOLEON Villanova University Villanova, Pennsylvania I N HIS RECENTLY published book, John F. X. Knasas seeks to answer this twofold inter-related question: What, according to Saint Thomas's expressed teaching, is the subject of metaphysics and how does the human mind proceed to attain it for the purpose of study? While he acknowledges a debt to Joseph Owens for certain of his basic positions, Knasas will claim that the book's argument is original in the way in which it opposes what he takes as realistically the subject of metaphysics at its initial stage (or with the only understanding of beingens -metaphysics requires to begin) to what will become this science 's subject at its later, more mature stage. Moreover, although he may contradict himself on this point, he will reject, as Saint Thomas's view, the position that a physical demonstration can establish the existence of immaterial being, be it God or angels. He will also argue at some length what he evidently considers a crucial epistemic procedure for the start of metaphysics, viz., that a series of judgments relating individuals back to their acts of existence (from whence they were originally abstracted) is required for the "judgmentally constituted multitude" from which the mind attains common being. Finally, since he will insist that abstraction must be controlled by the data, he will allow no room in Thomistic metaphysics for a beginning metaphysical intuition in which being is seen as not necessarily linked to matter and motion , nor for an a priori approach to its subject which would start *John F.

KONDOLEON from the nature of the knowing subject, viz., the human intellect, as open to and directed toward infinite being and intelligibility. In what follows I will discuss (and critically assess) each of these features of this book as well as address myself briefly to certain things the author has to say about the Thomistic " five ways." In the first three chapters Knasas is primarily concerned with showing that metaphysics cannot begin with a notion of being understood in the sense of ens commune. This sense of the notion traditionally includes both material and immaterial being. However, he argues, since (according to his reading of Aquinas) only metaphysics can demonstrate the existence of immaterial being , its subject cannot, at least at its outset, encompass such being , not even as something conceivable. He therefore opposes the view of Neo-Thomists who, basing themselve? on the now famous and frequently cited text from Saint Thomas's Expositio on Boethius's De Trinitate (Question 5, article 3), insist that metaphysics begins with the recognition that being is something separate from matter and motion (and not merely so in the mind's consideration by abstraction). This separation is understood in the so-called negative judgment of separation: " it is not of the nature of being to be in matter and motion (even though it is sometimes found therein)." On this point Knasas finds fault with " Natural Philosophy" Thomists, among whom he includes the Dominicans L.-B. Geiger (although this writer is barely mentioned and only in a footnote discussion) and James Weisheipl, both of whom have argued that the subject of metaphysics presupposes a demonstration from natural philosophy that immaterial, unchanging being exists (otherwise, they maintain, the separation of which Saint Thomas speaks in the De Trinitate Commentary would have no fundamentum in re). Again, his main argument with these Thomists is that no textual justification can be found for their view-indeed there is counter-textual evidence against it-that physical philosophy proves the existence of immaterial being and that, in the eyes of Aquinas, metaphysics awaits such a demonstration in order to begin. He equally rejects the position, one which he at- THE START OF METAPHYSICS 123 tributes above all to Maritain, that, prior to any argument that would establish the actual existence of God, being can be understood -and this thanks to an existential judgment in which existence is restored to the essence...
