Throughout his treatises on conduct, and especially in the N.E., Aristotle speaks of different types of inexactness that characterize matters of conduct or our knowledge of them - for example, lack of detail, being for the most part, being true for the most part, and deficiencies in demonstrative rigor. All of these types of inexactness are important for understanding Aristotle's view of ethical

This is especially so with the type of inexactness that Aristotle characterizes as being for the most part or being true for the most part; it has always raised doubts about the possibility of a discipline about matters of conduct that is demonstrative in character. In this essay I shall focus on the types of inexactness Aristotle designates as variation or indefiniteness and will explore any epistemological consequences they might have, as well as other problems they might raise in relation to other philosophical views of Aristotle. These types of inexactness have implications for the Aristotelian quest for definitions and the metaphysical presuppositions that underlie it, a quest he shares with his predecessors - Socrates and Plato. In particular, I shall argue that indefiniteness poses serious problems for the strong essentialist views that Aristotle shares with Socrates and Plato. Throughout the Socratic Dialogues, Plato represents Socrates as being committed to the view that all general terms designate kinds that have a fixed and invariant essential structure or nature. This type of metaphysical essentialism is thought to be true in every domain, including that studied by ethics (i.e., matters of conduct). The Socratic practice of seeking definitions and the type of definitions Socrates seeks presuppose this sort of metaphysical essentialism. Socrates' aim is to obtain real
