I argue that according to Socrates in the Phaedo we should not merely evaluate bodily pleasures and desires as worthless or bad, but actively avoid them. We need to avoid them because they change our values and make us believe falsehoods. This change in values and acceptance of falsehoods undermines the soul’s proper activity, making virtue and happiness impossible for us. I situate this account of why we should avoid bodily pleasures within Plato’s project in the Phaedo of providing Pythagorean (...) and Orphic ideas with clearer meanings and better justifications.

I argue that Meno’s Paradox targets the type of knowledge that Socrates has been looking for earlier in the dialogue: knowledge grounded in explanatory definitions. Socrates places strict requirements on definitions and thinks we need these definitions to acquire knowledge. Meno’s challenge uses Socrates’ constraints to argue that we can neither propose definitions nor recognize them. To understand Socrates’ response to the challenge, we need to view Meno’s challenge and Socrates’ response as part of a larger disagreement about the value (...) of inquiry. (shrink)

I argue that the technique Socrates describes in the Meno at 86e-87c allows him to make progress without definitions, even while accepting that definitions are necessary for knowledge. Some contend that the technique involves provisionally accepting a claim. I argue, instead, that it provides a secure biconditional that one can use to reduce the question one cares care about to a new question that one thinks will be easier to answer.

Aristotle presents a formal logic in the Prior Analytics in which the premises and conclusions are never conditionals. In this paper I argue that he did not simply overlook conditionals, nor does their absence reflect a metaphysical prejudice on his part. Instead, he thinks that arguments with conditionals cannot be syllogisms because of the way he understands the explanatory requirement in the definition of a syllogism: the requirement that the conclusion follow because of the premises. The key passage is Prior (...) Analytics I.32, 47a22–40, where Aristotle considers an argument with conditionals that we would consider valid, but which he denies is a syllogism. I argue that Aristotle thinks that to meet the explanatory requirement a syllogism must draw its conclusion through the way its terms are predicated of one another. Because arguments with conditionals do not, in general, draw their conclusions through predications, he did not include them in his logic. (shrink)

It is often claimed that Socrates rejects material causes in the Phaedo because they are not rational or not teleological. In this paper I argue for a new account: Socrates ultimately rejects material causes because he is committed to each change having a single cause. Because each change has a single cause, this cause must, on its own, provide an adequate explanation for the change. Material causes cannot provide an adequate explanation on their own and so Socrates rejects them. Aristotle (...) agrees that material causes cannot explain changes on their own, but by allowing the same change to have multiple causes, he makes room for a material cause. Aristotle draws attention to the anti-Platonic implications of his four causes in a passage in Physics II.3 (195a3- 14) that has been overlooked by commentators. (shrink)

This paper examines whether Socrates provides his interlocutors with good reasons to seek knowledge of what virtue is, reasons that they are in a position to appreciate. I argue that in the Laches he does provide such reasons, but they are not the reasons that are most commonly identified as Socratic. Socrates thinks his interlocutors should be motivated not by the idea that virtue is knowledge nor by the idea that knowledge is good for its own sake, but rather by (...) the idea that knowledge is needed to recognize what to aim at. His argument reaches the potentially life-altering conclusion that we should all seek knowledge of what virtue is. It is powerful precisely because it relies on uncontroversial premises that his interlocutors could be expected to accept. In laying out this argument, I distinguish different ways in which someone could count as a teacher of virtue. At the end of the article, I situate the argument within the debate about whether virtue is teachable. (shrink)

According to most scholars, in the Parts of Animals Aristotle frequently provides explanations in terms of material necessity, as well as explanations in terms of that-for-the-sake-of-which, i.e., final causes. In this paper, I argue that we misunderstand both matter and the way that Aristotle explains things using necessity if we interpret Aristotle as explaining things in terms of material necessity. Aristotle does not use the term “matter” very frequently in his detailed discussions of animal parts; when he does use it, (...) he typically identifies blood as matter. I argue that this is because blood is, for Aristotle, what properly nourishes and grows the other parts of the body and he views nourishment and growth as types of coming-to-be. The second half of the paper turns to necessity as a cause in the Parts of Animals. I argue that in the Parts of Animals Aristotle is not interested in distinguishing between what Aristotle elsewhere treats as very different types of necessity. (shrink)

Aristotle’s Motivation for Matter Why does Aristotle make matter so central to his account of the natural world, making it a principle of nature and one of the four causes? Although there is considerable interest in how Aristotle conceives of matter, scholars rarely investigate why he thinks of it as fundamental to the natural world. Some simply ask why Aristotle thinks there must be matter. Other interpreters do not even agree that we should ask this question; they claim that Aristotle (...) does not give reasons for needing matter because matter is an everyday notion we need not motivate. I think that in Physics I Aristotle gives us good reasons – perhaps even compelling ones – for thinking that matter is necessary for any understanding of the natural world. We, as interpreters, can use these reasons to understand what matter is for Aristotle, making progress where scholars have offered many incompatible interpretations. The first chapter of the dissertation presents my basic account of why Aristotle needs matter and what it is. I argue that Aristotle makes matter central to his natural philosophy because it is needed in order to understand change. Specifically, in order for there to be change, there must be something whose very nature is to undergo change. This is what matter is for Aristotle: the thing whose very nature is to undergo change. Since matter is picked out by its role in change, the very same thing will be matter and other things, based on what other roles it has. Just as the same person can be a doctor and a builder, so the same person can be a doctor and matter. This chapter also highlights the strength of my account by arguing against a rival interpretation of Aristotle’s motivation for matter, according to which matter is needed so that something persists through change. The second chapter argues for my interpretation through a close reading of Aristotle’s Physics I. (shrink)

Aristotle argued that in theory one could acquire knowledge of the natural world. But he did not stop there; he put his theories into practice. This volume of new essays shows how Aristotle's natural science and philosophical theories shed light on one another. The contributors engage with both biological and non-biological scientific works and with a wide variety of theoretical works, including Physics, Generation and Corruption, On the Soul, and Posterior Analytics. The essays focus on a number of themes, including (...) the sort of explanation provided by matter; the relationship between matter, teleology, and necessity; cosmic teleology; how an organism's soul and faculties relate to its end; how to define things such as sleep, void, and soul; and the proper way to make scientific judgments. The resulting volume offers a rich and integrated view of Aristotle's science and shows how it fits with his larger philosophical theories. (shrink)

This essay considers three case studies of Aristotle’s use of matter, drawn from three different scientific contexts: menstrual fluid as the matter of animal generation in the Generation of Animals, the living body as matter of an organism in Aristotle’s On the Soul (De Anima), and the matter of elemental transformation in Generation and Corruption. I argue that Aristotle conceives of matter differently in these treatises (1) because of the different sorts of changes under consideration, and (2) because sometimes he (...) is considering the matter for one specific change, and sometimes the matter for all of a thing’s natural changes. My account allows me to explain some of the strange features that Aristotle ascribes to the matter for elemental transformation in Generation and Corruption II. These features were interpreted by later commentators as general features of all matter. I argue that they are a result of the specific way that Aristotle thinks about the transmutation of the elements. (shrink)

According to many interpreters, Socrates in the Euthyphro thinks that an answer to ‘what is the holy?’ should pick out some feature that is prior to being holy. While this is a powerful way to think of answers to the ‘what is it?’ question, one that Aristotle develops, I argue that the Euthyphro provides an important alternative to this Aristotelian account. Instead, an answer to ‘what is the holy?’ should pick out precisely being holy, not some feature prior to it. (...) I begin by showing how this interpretation allows for a straightforward reading of a key argument: Socrates’ refutation of Euthyphro’s proposal that the holy is the god-loved. Then I address considerations that seem to favor the Aristotelian account. I end by explaining how answers to ‘what is f-ness?’ questions are informative on this account, even though they do not identify anything other than f-ness. (shrink)

A reply to Melissa Lane's "Antianarchia: interpreting political thought in Plato" In these comments I focus on how to think of antianarchia as an element of Plato's political thought, and in doing so raise some methodological questions about how to read Plato’s dialogues, focusing on what is involved in attributing views to Plato in general.

In the first half of this book, Gail Fine provides a renewed defense of her reading of Meno's famous paradox; in the second, she provides novel accounts of how Aristotle, the Stoics, the Epicureans, and Sextus Empiricus responded to the paradox. For reasons of space, I focus on the first half, where Fine defends the same basic account of Meno's paradox she put forward in her influential "Inquiry in the Meno". The book goes further, considering and dismissing several alternatives not (...) considered there and arguing at length against recent accounts in the secondary literature, especially those of Dominic Scott and David Charles.According to Fine, Meno's paradox rests on Meno misunderstanding what Socrates means...
