This new edition introduces students to fresh approaches to Platonic dialogues (...) while advancing the next generation of research. Of its seventeen chapters, nine are entirely new, written by a new generation of scholars. Six others have been thoroughly revised and updated by their original authors. The volume covers the full range of Plato's interests, including ethics, political philosophy, epistemology, metaphysics, aesthetics, religion, mathematics, and psychology. Plato's dialogues are approached as unified works and considered within their intellectual context, and the revised introduction suggests a way of reading the dialogues that attends to the differences between them while also tracing their interrelations. The result is a rich and wide-ranging volume which will be valuable for all students and scholars of Plato. (shrink)

Plato's Phaedo is a literary gem that develops many of his most famous ideas. David Ebrey's careful reinterpretation argues that the many debates about the dialogue cannot be resolved so long as we consider its passages in relative isolation from one another, separated from their intellectual background. His book shows how Plato responds to his literary, religious, scientific, and philosophical context, and argues that we can only understand the dialogue's central ideas and arguments in light of its overall (...) structure. This approach yields new interpretations of the dialogue's key ideas, including the nature and existence of 'Platonic' forms, the existence of the soul after death, the method of hypothesis, and the contemplative ethical ideal. Moreover, this comprehensive approach shows how the characters play an integral role in the Phaedo's development and how its literary structure complements Socrates' views while making its own distinctive contribution to the dialogue's drama and ideas.

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. (shrink)

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)

This article argues that the Phaedo is written as a new sort of story of how a hero faces death; this story provides an alternative to existing tragedy, as understood by Plato. The opening of the Phaedo makes clear that two features that Plato closely associates with tragedy, pity and lamentation, are inappropriate responses to Socrates’ impending death, and that tuchē (chance) did not affect his happiness. This is the first step in the dialogue’s sustained engagement with tragedy. Tragedy for (...) Plato falls under the category of stories about heroes and gods. Plato wrote the Phaedo so that we would see Socrates as a philosophical hero, a replacement for traditional heroes such as Theseus or Heracles. I argue that in fact the Phaedo meets every requirement in Republic Books 2–3 for how to tell stories about heroes and gods and so belongs to the same broad category as tragedy. Within this framework, it tells its new story of how the true hero faces death. (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)

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)

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 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)

This chapter offers a guide to reading Plato’s dialogues, including an overview of his corpus. We recommend first considering each dialogue as its own unified work, before considering how it relates to the others. In general, the dialogues explore ideas and arguments, rather than presenting parts of a comprehensive philosophical system that settles on final answers. The arc of a dialogue frequently depends on who the individual interlocutors are. We argue that the traditional division of the corpus (into Socratic, middle, (...) late stages) is useful, regardless of whether it is a chronological division. Our overview of the corpus gives special attention to the Republic, since it interweaves so many of his key ideas, even if nearly all of them receive longer treatments in other dialogues. Although Plato recognized the limits inherent in written (as opposed to spoken) philosophy, he devoted his life to producing these works, which are clearly meant to help us seek the deepest truths. Little can be learned from reports of Plato’s oral teaching or the letters attributed to him. Understanding the dialogues on their own terms is what offers the greatest reward. (shrink)

In Plato’s dialogues, Socrates calls things like justice, piety, and largeness “forms.” In several of these dialogues, he makes clear that forms are very different from familiar objects like tables and trees. Why, exactly, does he think that they differ and how are they supposed to do so? This chapter argues that in the Phaedo Socrates does not assume that they are different, but rather, over five stages of the dialogue, provides an account of how and why they do so. (...) To fully understand the claims made in the first stage, one must look to the next stage, and so on until the final stage. Socrates' ultimate reason for distinguishing forms from ordinary objects does not depend on our intuitions about things like justice and largeness, nor on the distinction between universals and particulars. Ultimately, forms cannot be ordinary objects because the form of f-ness must cause every f-thing to be f, but no ordinary object could serve as such a cause. They cannot do so because they have multiple parts and are receptive of opposites; by contrast, the form of f-ness must be simple and unchanging, since it causes every f-thing to be f. (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.

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)

In the Phaedo, Socrates leads us to expect that his final argument will address the details of Cebes’ cloakmaker objection. Nonetheless, almost all commentators treat the final argument as unconnected to these details. This paper argues that close attention to Cebes’ objection, Socrates’ restatement of it, and Socrates’ final argument shows that the final argument does offer a detailed response. According to the objection, the soul suffers as it brings life to the body, which ultimately leads to its destruction. Socrates (...) argues that, on the contrary, bringing life to the body is precisely what ensures the soul’s immortality and indestructability. Cebes’ objection targets Socrates’ so-called ‘affinity argument’. In responding to Cebes’ objection, the final argument fills in the account of the soul that Socrates put forward in the affinity argument. In doing so, it identifies one precise way in which the soul is akin to the divine. (shrink)

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...

David Hume's Enquiry concerning Human Understanding is the definitive statement of the greatest philosopher in the English language. His arguments in support of reasoning from experience, and against the "sophistry and illusion"of religiously inspired philosophical fantasies, caused controversy in the eighteenth century and are strikingly relevant today, when faith and science continue to clash. The Enquiry considers the origin and processes of human thought, reaching the stark conclusion that we can have no ultimate understanding of the physical world, or (...) indeed our own minds. In either sphere we must depend on instinctive learning from experience, recognizing our animal nature and the limits of reason. Hume's calm and open-minded skepticism thus aims to provide a new basis for science, liberating us from the "superstition" of false metaphysics and religion. His Enquiry remains one of the best introductions to the study of philosophy, and his edition places it in its historical and philosophical context. (shrink)

A leading political theorist’s groundbreaking defense of ideal conceptions of justice in political philosophy Throughout the history of political philosophy and politics, there has been continual debate about the roles of idealism versus realism. For contemporary political philosophy, this debate manifests in notions of ideal theory versus nonideal theory. Nonideal thinkers shift their focus from theorizing about full social justice, asking instead which feasible institutional and political changes would make a society more just. Ideal thinkers, on the other hand, question (...) whether full justice is a standard that any society is likely ever to satisfy. And, if social justice is unrealistic, are attempts to understand it without value or importance, and merely utopian? Utopophobia argues against thinking that justice must be realistic, or that understanding justice is only valuable if it can be realized. David Estlund does not offer a particular theory of justice, nor does he assert that justice is indeed unrealizable—only that it could be, and this possibility upsets common ways of proceeding in political thought. Estlund engages critically with important strands in traditional and contemporary political philosophy that assume a sound theory of justice has the overriding, defining task of contributing practical guidance toward greater social justice. Along the way, he counters several tempting perspectives, including the view that inquiry in political philosophy could have significant value only as a guide to practical political action, and that understanding true justice would necessarily have practical value, at least as an ideal arrangement to be approximated. Demonstrating that unrealistic standards of justice can be both sound and valuable to understand, Utopophobia stands as a trenchant defense of ideal theory in political philosophy. (shrink)

The zetetic turn in epistemology raises three questions about epistemic and zetetic norms. First, there is the relationship question: what is the relationship between epistemic and zetetic norms? Are some epistemic norms zetetic norms, or are epistemic and zetetic norms distinct? Second, there is the tension question: are traditional epistemic norms in tension with plausible zetetic norms? Third, there is the reaction question: how should theorists react to a tension between epistemic and zetetic norms? Drawing on an analogy to practical (...) philosophy, I develop a focal point view to resolve these motivating questions. On the focal point view, traditional epistemic norms and zetetic norms answer different types of normative questions. There is nevertheless a familiar type of evaluative tension between traditional epistemic norms and zetetic norms, but this tension is an unavoidable feature of the normative landscape and not a sign that traditional epistemic norms need revision. But if traditional epistemic norms are not zetetic norms, then in what sense is zetetic epistemology a project for epistemologists? I conclude by articulating a sense in which some nontraditional epistemic norms are zetetic norms, and in which zetetic epistemology is an important part of the study of theoretical rationality.

One of the enduring concerns of moral philosophy is deciding who or what is deserving of ethical consideration. Much recent attention has been devoted to the "animal question" -- consideration of the moral status of nonhuman animals. In this book, David Gunkel takes up the "machine question": whether and to what extent intelligent and autonomous machines of our own making can be considered to have legitimate moral responsibilities and any legitimate claim to moral consideration. The machine question poses a (...) fundamental challenge to moral thinking, questioning the traditional philosophical conceptualization of technology as a tool or instrument to be used by human agents. Gunkel begins by addressing the question of machine moral agency: whether a machine might be considered a legitimate moral agent that could be held responsible for decisions and actions. He then approaches the machine question from the other side, considering whether a machine might be a moral patient due legitimate moral consideration. Finally, Gunkel considers some recent innovations in moral philosophy and critical theory that complicate the machine question, deconstructing the binary agent--patient opposition itself. Technological advances may prompt us to wonder if the science fiction of computers and robots whose actions affect their human companions could become science fact. Gunkel's argument promises to influence future considerations of ethics, ourselves, and the other entities who inhabit this world. (shrink)

This book is an attempt to get to the bottom of an acute and perennial tension between our best scientific pictures of the fundamental physical structure of the world and our everyday empirical experience of it. The trouble is about the direction of time. The situation (very briefly) is that it is a consequence of almost every one of those fundamental scientific pictures--and that it is at the same time radically at odds with our common sense--that whatever can happen can (...) just as naturally happen backwards. Albert provides an unprecedentedly clear, lively, and systematic new account--in the context of a Newtonian-Mechanical picture of the world--of the ultimate origins of the statistical regularities we see around us, of the temporal irreversibility of the Second Law of Thermodynamics, of the asymmetries in our epistemic access to the past and the future, and of our conviction that by acting now we can affect the future but not the past. Then, in the final section of the book, he generalizes the Newtonian picture to the quantum-mechanical case and (most interestingly) suggests a very deep potential connection between the problem of the direction of time and the quantum-mechanical measurement problem. The book aims to be both an original contribution to the present scientific and philosophical understanding of these matters at the most advanced level, and something in the nature of an elementary textbook on the subject accessible to interested high-school students.

By means of an example, shows the possibility of beliefs that are separately rational whilst together inconsistent.

How should one react when one has a belief, but knows that other people—who have roughly the same evidence as one has, and seem roughly as likely to react to it correctly—disagree? This paper argues that the disagreement of other competent inquirers often requires one to be much less confident in one’s opinions than one would otherwise be.

I attempt to get as clear as possible on the chain of reasoning by which irreversible macrodynamics is derivable from time-reversible microphysics, and in particular to clarify just what kinds of assumptions about the initial state of the universe, and about the nature of the microdynamics, are needed in these derivations. I conclude that while a “Past Hypothesis” about the early Universe does seem necessary to carry out such derivations, that Hypothesis is not correctly understood as a constraint on the (...) early Universe’s entropy.

Originally intended for scientists (...) and professionals, Understanding Animal Welfare has also found a home in undergraduate classrooms. It is now the essential text for students, practitioners, veterinarians, and researchers in animal welfare and related fields. (shrink)

We start by presenting three different views that jointly imply that every person has many conscious beings in their immediate vicinity, and that the number greatly varies from person to person. We then present and assess an argument to the conclusion that how confident someone should be in these views should sensitively depend on how massive they happen to be. According to the argument, sometimes irreducibly de se observations can be powerful evidence for or against believing in metaphysical theories.

Unprecedented advances in medicine, genetic engineering, and demographic forecasting raise new questions that strain the categories and assumptions of traditional ethical theories. Heyd's approach resolves many paradoxes in intergenerational justice, while offering a major test case for the profound problems of the limits of ethics and the nature of value. This title is part of UC Press's Voices Revived program, which commemorates University of California Press’s mission to seek out and cultivate the brightest minds and give them voice, reach, and (...) impact. Drawing on a backlist dating to 1893, Voices Revived makes high-quality, peer-reviewed scholarship accessible once again using print-on-demand technology. This title was originally published in 1992.

Worries about mental causation are prominent in contemporary discussions of the mind and human agency. Originally, the problem of mental causation was that of understanding how a mental substance (thought to be immaterial) could interact with a material substance, a body. Most philosophers nowadays repudiate immaterial minds, but the problem of mental causation has not gone away. Instead, focus has shifted to mental properties. How could mental properties be causally relevant to bodily behavior? How could something mental qua mental cause (...) what it does? After looking at the traditional Problem of Interaction, we survey various versions of the property-based problem and look at proposed solutions to them. (shrink)

Film is an art form with a language and an aesthetic all its own. Since 1979, David Bordwell and Kristin Thompson's Film Art has been the best-selling and widely respected introduction to the analysis of cinema. Taking a skills-centered approach supported by a wide range of examples from various periods and countries, the authors strive to help students develop a core set of analytical skills that will deepen their understanding of any film, in any genre. Frame enlargements throughout the (...) text enable students to view images taken directly from completed films, while an optional, text-specific tutorial CD-ROM helps clarify and reinforce specific concepts addressed in the text with the use of film clips. Building on these strengths, the ninth edition adds coverage of new technologies, updated examples, and references to the authors' acclaimed weblog to provide unparalleled currency and connect students with the world of cinema today.

Our aim in this entry is to articulate the state of the art in the moral psychology of personal identity. We begin by discussing the major philosophical theories of personal identity, including their shortcomings. We then turn to recent psychological work on personal identity and the self, investigations that often illuminate our person-related normative concerns. We conclude by discussing the implications of this psychological work for some contemporary philosophical theories and suggesting fruitful areas for future work on personal identity.
