This is an investigation of Aristotle's conception of accidental compounds (or "kooky objects," as Gareth Matthews has called them)—entities such as the pale man and the musical man. I begin with Matthews's pioneering work into kooky objects, and argue that they are not so far removed from our ordinary thinking as is commonly supposed. I go on to assess their utility in solving some familiar puzzles involving substitutivity in epistemic contexts, and compare the kooky object approach to more modern approaches involving the notion of referential opacity. I conclude by proposing that Aristotle provides an implicit role for kooky objects in such metaphysical contexts as the Categories and Metaphysics.

This is an examination of Aristotle's notion of an "accidental being" -- something intermediate between a substance and a property. An accidental being (sometimes called "accidental compound" or "kooky object") is an ephemeral object, typically the compound of a substance and a property, that exists for only as long as its components are united. I set out the role that accidental beings play in Aristotle's solutions to several philosophical problems. I also investigate the similarity between these beings and the individual non-substances of Aristotle's Categories. Finally, I propose that accidental beings can be assimilated into a more contemporary conceptual scheme as events -- the states or conditions that substances are in or undergo.

Quine, in an influential passage, characterizes a certain kind of metaphysical view as "Aristotelian essentialism." Recent work on Aristotle suggests that he may not have been an essentialist in Quine's sense. This paper examines the question whether, and to what extent, Aristotle is committed to the kind of essentialism Quine discusses. Various promising areas of Aristotle's thought (alteration vs. coming-to-be and passing-away, kath' hauto predication) are examined and found wanting as sources of essentialism. Instead, Aristotle is found to be committed to essentialism in the hylomorphic conception of substance featured in the late books of the Metaphysics, despite the superficially anti-essentialistic appearance of the conception of matter as the ultimate subject of predication. Essentialism is part and parcel of Aristotle's conception of substances as the basic individuals.
