Aristotle's Metaphysics. 1.
The Subject Matter of Aristotle’s Metaphysics Aristotle himself described his subject matter in a variety of ways: as ‘first philosophy’, or ‘the study of being qua being’, or ‘wisdom’, or ‘theology’. A comment on these descriptions will help to clarify Aristotle’s topic. In Metaphysics A.1, Aristotle says that “all men suppose what is called wisdom (sophia) to deal with the first causes (aitia) and the principles (archai) of things” (981b28), and it is these causes and principles that he proposes to study in this work.
