Discussions of Aristotle’s Metaphysics Z tend to treat it either as an independent treatise on substance and essence or as preliminary to the main conclusions of the Metaphysics. I argue instead that Z is central to Aristotle’s project of first philosophy in the Metaphysics: the first philosopher seeks the first causes of being qua being, especially substances, and in Z, Aristotle establishes that essences or forms are the first causes of being of perceptible substances. I also argue that the centrality (...) of Z to first philosophy is compatible with its status as theology. (shrink)

In the first argument of Metaphysics Μ.2 against the Platonist introduction of separate mathematical objects, Aristotle purports to show that positing separate geometrical objects to explain geometrical facts generates an ‘absurd accumulation’ of geometrical objects. Interpretations of the argument have varied widely. I distinguish between two types of interpretation, corrective and non-corrective interpretations. Here I defend a new, and more systematic, non-corrective interpretation that takes the argument as a serious and very interesting challenge to the Platonist.

This paper examines Aristotle’s argument in Eudemian Ethics 1.8 that eudaimonia, the best practicable good, is the telos of the practicable goods. Aristotle defers to the Platonists in thinking that the best practicable good is the first practicable good and the cause of the other practicable goods’ goodness. But, on his view, it is the telos of the practicable goods that has these two properties. Aristotle’s argument for this latter claim is supported by his view, more fully discussed in Posterior (...) Analytics 2.11, of how final causes explain normative facts. (shrink)

I argue that Aristotle’s unmodern conception of politics can only be understood by first understanding his distinctive picture of human agency and the excellence of political wisdom. I therefore undertake to consider three related puzzles: why at the outset of the Nicomachean Ethics [NE] is the human good said to be the same for a city and for an individual, such that the NE’s inquiry is political? why later on in the NE is political wisdom said to be the same (...) state of soul as practical wisdom? why in the Politics does Aristotle identify practical wisdom as the peculiar excellence of rulers when deliberation was said to be the common work of all citizens insofar as they are genuinely citizens? While these puzzles have individually received treatment in the literature, they have seldom been treated together. Taken independently, the passages in question can seem to express a more familiar conception of politics. In particular, each of the sameness claims made in and has too easily been assimilated to a more modern conception of the relation of ethics to politics and thereby domesticated. As I hope to show, in Aristotle is not simply asserting that the human good in a city supervenes on the good as achieved by its inhabitants ; and in he is not claiming only that political wisdom is a species of practical wisdom, but is rather asserting a more thoroughgoing identity between various types of deliberative excellence that are conventionally distinguished and assigned different names. Working through these passages will provide a sufficient basis for tackling, the question about the respective excellences of rulers and citizens. I will show that, despite his restriction of the exercise of practical wisdom to rulers, Aristotle imagines that non-ruling citizens will also exercise their political agency and thereby require a distinct rational excellence. More precisely, for Aristotle, there are two forms of political agency, deliberation on behalf of one’s community, which is perfected by practical-political wisdom, and the comprehension exercised by citizens on the basis of the view of life preserved by their character-virtues. Understood this way, the division of labor between rulers and citizens does not generate two spheres of activity, political and private, which could have unrelated excellences or concern distinct goods.

Aristotle is often taken to define priority in being in Metaphysics Δ.11, where he says that those things are prior in being which “admit of being without other things, while these others cannot be without them: a division which Plato used” (1019a3-4). But Aristotle’s pattern of arguments about priority – some of which use Plato’s Test and others of which use distinct, causal tests – looks puzzling if Plato’s Test is his definition. This paper offers a new interpretation of Δ.11 (...) on which it offers a guide to the Aristotelian use of Plato’s Test, given that being is said in many ways, rather than endorsing it as Aristotle’s own definition of priority. This reading illuminates Aristotle’s pattern of arguments in the corpus – explaining why Aristotle uses Plato’s Test in some cases and departs from it in others – and suggests a plausible story about how these arguments were shaped by engaging with Plato.

In Metaphysics Λ7 1072b30–1073a3, Aristotle introduces a Speusippean theory according to which ‘what is most beautiful and best is not en archēi’. Through a detailed analysis of the passage, I argue that Aristotle’s refutation of Speusippus’ thesis is favoured by the introduction of the seed example, which conflates both ontological and temporal priority. The elements gathered from the analysis of Aristotle’s polemical strategy will support a broader conclusion: Speusippus’ reason not to characterise his principle(s) as (the) good is related to (...) the problematic relationship Forms and sensibles had within Plato’s account, or, in other words, participation.

: Metaphysics B considers two sets of views that hypostatize mathematicals. Aristotle discusses the first in his B.2 treatment of aporia 5, and the second in his B.5 treatment of aporia 12. The former has attracted considerable attention; the latter has not. I show that aporia 12 is more significant than the literature suggests, and specifically that it is directly addressed in M.2 – an indication of its importance. There is an immediate problem: Aristotle spends most of M.2 refuting the (...) view that mathematicals are separate; but the B.5 mathematicals are inherent. I argue that the B.5 inherence is compatible with the M.2 separateness, and further, that aporia 12 is more than just a puzzle about the hypostatization of mathematicals. It is also a puzzle about the ontological status of mathematicals relative to sensibles. (shrink)
