First Philosophy and the Kinds of Substance JOSEPH G. DEFILIPPO ON A CERTAIN INTERPRETATION Aristotle's Metaphysics contains two incompati- ble conceptions of metaphysics or, as he calls it, first philosophy. At two points in the treatise he identifies first philosophy with theology . Along with this identification comes a certain view about the nature and number of theoretical sciences. We are told in E. 1 that there are three: natural philosophy, mathematics, and theology. Natural philosophy deals with nonseparate,' mutable substance, (...) whereas the objects of mathematics are nonseparate but immutable. It is left to theology to study substance that is both separate and immutable . Hence it is prior to the other two theoretical sciences and more worthy of honor. But for Aristotle first philosophy is not merely a compartmentalized science concerned with a single genus or kind of substance; he means it to be a universal science of "being qua being." Indeed, it is the status of first philosophy as the primary theoretical science that is supposed to provide for its universal scope. As he says in E. 1, it is universal "in this way, because it is first" 0o26a3o-31). Large and well- known difficulties loom in the way of this tantalizing idea. First, it is not clear how theology's position of primacy is the cause of its universal scope; if anything, divine substance seems to be a special item within a more.. (shrink)

In the Metaphysics Aristotle explicitly identifies first philosophy, the science of "being qua being," with theology . But the treatise never explains how theology could also be a universal science of being. This dissertation will attempt to provide such an explanation. Its procedure will differ from past approaches by attempting to understand the programmatic remarks of VI.1 in the light of Aristotle's actual conception of god, his theology proper. ;Chapter two examines Aristotle's notion of god as a self-thinker. It argues (...) that the god of Metaphysics XII is not narcissistically engaged in self-contemplation. Rather, Aristotle's statements that god "thinks himself" are meant to express the fact that he is an essentially active mind and therefore a pure actuality. ;Chapter three examines what it means for something to be a pure actuality, and in particular, a purely actual mind. It argues, based on a comparison between god and the fullest actuality of human thought, that the content of the divine thinking is just the principles of "being qua being." ;Chapter four addresses directly Aristotle's conception of first philosophy. It argues that the conception of theology as a universal science of being is grounded in the application of two kinds of priority relations. Substance is the focal meaning ) of being, while god is the first of the series of three kinds of substance. ;In concluding, I first review Aristotle's conception of substance in Metaphysics VII. Following Frede , I contend that Aristotle understands sensible substance in its primary sense to be form. Accordingly, there are two grounds on which Aristotle may consistently and intelligently identify metaphysics with theology. As a pure form god is the first kind of substance. He is therefore the best example of a being, knowledge of which is necessary to understand being in general. As an essentially self-thinking, and therefore purely actual mind, god possesses the most universal knowledge. He is therefore the most appropriate object for a science of being qua being, for one comes to have knowledge of god by coming to know the principles of being qua being. (shrink)
