The Parmenides is arguably the pivotal text for understanding the Platonic corpus as a whole. I offer a critical analysis that takes as its key the closely constructed dramatic context and mimetic irony of the dialogue. Read with these in view, the contradictory characterizations of the "one" in the hypotheses dissolve and reform as stages in a systematic response to the objections that Parmenides earlier posed to the young Socrates' notions of forms and participation, potentially liberating Socrates from his dependence (...) on sensible simile and yielding a distinctively conceptual articulation of the difference and relation of forms and their sensible participants. The dialogue as a whole thereby functions as the means for the "conversion" of the soul to eidetic being for which Plato has the elder Socrates call in Republic VII. (shrink)

In the Statesman , Plato brings together--only to challenge and displace--his own crowning contributions to philosophical method, political theory, and drama. In his 1980 study, reprinted here, Mitchell Miller employs literary theory and conceptual analysis to expose the philosophical, political, and pedagogical conflict that is the underlying context of the dialogue, revealing that its chaotic variety of movements is actually a carefully harmonized act of realizing the mean. The original study left one question outstanding: what specifically, in the (...) metaphysical order of things, motivated the nameless Visitor from Elea to abandon bifurcation for his consummating non-bifurcatory division of fifteen kinds at the end of the dialogue? Miller addressed in a separate essay, first published in 1999 and reprinted here. In it, he opens the horizon of interpretation to include the new metaphysics of the Parmenides , the Philebus , and the "unwritten teachings." "This study demonstrates how the Statesman is the culminating expression of Plato's lifelong effort, both in Athens and in the Academy, to bring metaphysical insight to the unending political crisis of his times."The Philosopher in Plato's Statesman a trail-blazing work. While not every reader will agree with the lessons Miller himself draws from this approach, none should fail to be impressed by its interpretive power. All this is exciting stuff. The interpretive pathway on which Miller has embarked has the potential for changing the face of scholarship on the late Platonic dialogues. Parmenides [Publishing] is to be commended for making these two important contributions available under a single cover." -- Kenneth Sayre, Professor of Philosophy, University of Notre Dame "Miller casts considerable light on virtually every aspect of the dialogue. . . . All in all, this book is an outstanding contribution to our understanding of the Statesman." -- Stanley Rosen, Borden Parker Bowne Professor of Philosophy, Boston University MITCHELL MILLER is Professor of Philosophy at Vassar College. He is the author of Plato's Parmenides. (shrink)

An effort to track the movement of thought in the proem of the poem in order to discover in it the context for the disclosure of the "is" in fr. s 2 and 8. Close attention to symbolic imagery and historical allusions, and to the philosophical power of the unthinkable "nothing".

In lieu of an abstract, here is a brief excerpt of the content:Reviewed by:The Legacy of Parmenides, Eleatic Monism and Later Presocratic Thought by Patricia CurdMitchell MillerPatricia Curd. The Legacy of Parmenides, Eleatic Monism and Later Presocratic Thought. Princeton: Princeton University Press, 1998. Pp. xv + 280. Cloth, $45.00.Curd confronts a puzzle in early Greek philosophy. Parmenides’ teaching is traditionally understood as “numerical monism”: “there is only one thing or item in the universe” (66). But his successors, though accepting his (...) key claims that “what-is-not” is not to be thought and becoming must therefore be denied, begin straightaway, without argument, from a plurality of ultimate entities—Anaxagoras from the chremata, Empedocles from his four roots and Love and Strife, Leucippus and Democritus from atoms and the void. Did they peremptorily reject Parmenides’ monism? Did they simply fail to understand it? Curd proposes, instead, that Parmenides was not a “numerical monist” in the first place. Recasting Mourelatos’ notion of speculative predication, she offers accounts of the Aletheia- and the Doxa-sections of the poem in which Parmenides emerges as a “predicational monist.” In the Aletheia, Curd’s Parmenides subjects to critique the predications by which inquiry arrives at the “nature” of something; the “signs” of B8 are the criteria that, in accord with his rejection of negative predications as uninformative, each “nature” must meet. It is not the “universe” but rather each “nature” by itself that must be “a whole of a single kind” (B8.3), “all together one, cohesive” (B8.5–6), and “not divisible” (B8.22)—how many such “natures” a theory may posit is simply not at issue. In the Doxa, Curd’s Parmenides has a twofold purpose: by the “deceptive order of [the goddess’] words” Parmenides poses a test, challenging his hearers to recognize that since “Light” and “Night” are “enantiomorphic opposites” with each in its very “nature” not the other, they fail to meet the criteria of B8; at the same time, he provides a model that we can use to assess or construct cosmological theories. By this interpretation of Parmenides Curd clears the ground for her account of his “legacy.” In her final chapters she offers pointed readings of Anaxagoras, Empedocles, the Atomists, Philolaus, Diogenes of Apollonia, and early Plato, arguing that each adopts Parmenides’ “predicational monism,” affirming the indivisibly one and unchanging character of each of the “natures” fundamental to the sensible world.This major new proposal will be of compelling interest to all scholars of the presocratics. Some possible limitations and basic questions to consider:1. There are significant regions of the proem, of presocratic thought, and of modern commentary yet to be examined. B9, crucial to interpreting the error of mortals at B8.53–54, and the orienting symbolism in the proem are only cursorily treated. Hesiod gets barely a mention in Curd’s otherwise valuable survey of the appeals to opposites in pre-Parmenidean thought. In taking the early Owen’s existential reading of Parmenides’ [End Page 157] esti and her own notion of the “is” of “informative identity” as the two fundamental alternatives, she leaves undiscussed the so-called “fused” predicative-existential reading.2. How narrowly focused does Curd’s reading require us to keep Parmenides’ esti? When she discusses B8, she speaks of “what-is” and “what-is-not.” But if we approach B8 in light of her reading of B2 and read to eon in the context of a speculative predication of the form “x is F,” shouldn’t we speak of it as “what x is”—and of the corresponding negation as “what x is not”? Does Curd seek to preserve the veridical-existential implication of “x is F,” namely, that as the nature that defines x, it is F that truly or most fully exists? Clarification of this issue need not require an either/or choice between senses of “is.” It may well be that to appreciate fully Parmenides’ krisis, “is or is not,” and his paradoxical notion of “nothing,” we need to recover an interplay between speculative-predicative, existential, and veridical nuances—especially if, with Curd, we open ourselves to an unfolding history of perspectives extending all the way to Plato.3. To construe Parmenides as only a “predicational monist” requires... (shrink)

A review of Drew Hyland's Questioning Platonism.

A close reading of Theogony 116-133, showing the logic of opposites and of whole/part relations that governs Hesiod's account of cosmogenesis, refuting the traditional interpretation of the birth of Chaos as the split between heaven and earth, and providing evidence that Hesiod considered and decided against making Tartaros the parent of the cosmos.

The idea that there could be spatially extended mereological simples has recently been defended by a number of metaphysicians (Markosian 1998, 2004; Simons 2004; Parsons (2000) also takes the idea seriously). Peter Simons (2004) goes further, arguing not only that spatially extended mereological simples (henceforth just extended simples) are possible, but that it is more plausible that our world is composed of such simples, than that it is composed of either point-sized simples, or of atomless gunk. The difficulty for these (...) views lies in explaining why it is that the various sub-volumes of space occupied by such simples, are not occupied by proper parts of those simples. Intuitively at least, many of us find compelling the idea that spatially extended objects have proper parts at every sub-volume of the region they occupy. It seems that the defender of extended simples must reject a seemingly plausible claim, what Simons calls the geometric correspondence principle (GCP): that any (spatially) extended object has parts that correspond to the parts of the region that it occupies (Simons 2004: 371). We disagree. We think that GCP is a plausible principle. We also think it is plausible that our world is composed of extended simples. We reconcile these two notions by two means. On the one hand we pay closer attention to the physics of our world. On the other hand, we consider what happens when our concept of something—in this case space—contains elements not all of which are realized in anything, but instead key components are realized in different features of the world.

A number of recent theories of quantum gravity lack a one-dimensional structure of ordered temporal instants. Instead, according to many of these views, our world is either best represented as a single three-dimensional object, or as a configuration space composed of such three-dimensional objects, none of which bear temporal relations to one another. Such theories will be empirically self-refuting unless they can accommodate the existence of conscious beings capable of representation. For if representation itself is impossible in a timeless world, (...) then no being in such a world could entertain the thought that a timeless theory is true, let alone believe such a theory or rationally believe it. This paper investigates the options for understanding representation in a three-dimensional, timeless, world. Ultimately it concludes that the only viable option is one according to which representation is taken to be deeply non-naturalistic. Ironically then we are left with two seemingly very unattractive options. Either a very naturalistic motivation—taking seriously a live view in fundamental physics—leads us to a very non-naturalistic view of the mental, or else views in the philosophy of mind partly dictate what is an acceptable theory in physics.

This paper aims to provide an overview of the conceptual terrain of what we call conative accounts of personal identity. These are views according to which the same-person relation in some sense depends on a range of broadly conative phenomena, especially desires, behaviours and conventions. We distinguish views along three dimensions: what role the conations play, what kinds of conations play that role, and whether the conations that play that role are public or private. We then offer a more detailed (...) consideration of direct private conativism—the version of conativism that we favour—before considering how conativists ought respond to a general worry, according to which any conativist view will lead us to be radically pluralist about persons. (shrink)

In this paper we argue that reflection on the patterns of practical concern that agents like us exhibit strongly suggests that the same person relation comes in continuous degrees rather than being an all or nothing matter. We call this the SP-degree thesis. Though the SP-degree thesis is consistent with a range of views about personal-identity, we argue that combining desire-first approaches to personal-identity with the SP-degree thesis better explains our patterns of practical concern, and hence gives us reason to (...) endorse such an approach. We then argue that the combination of the SP-degree thesis and the desire-first approach are best modelled by a stage-theoretic view of persistence according to which temporal counterpart relations are non-symmetric relations that come in continuous degrees. Ultimately, we think that the overall appeal of this package of views provides reason to accept the package: reasons that outstrip the reasons we have to endorse any particular member of the package.

The paper defends a combination of perdurantism with mereological universalism by developing semantics of temporary predications of the sort ’some P is/was/will be (a) Q’. We argue that, in addition to the usual application of causal and other restrictions on sortals, the grammatical form of such statements allows for rather different regimentations along three separate dimensions, according to: (a) whether ‘P’ and ‘Q’ are being used as phase or substance sortal terms, (b) whether ‘is’, ‘was’, and ‘will be’ are the (...) ‘is’, ‘was’, ‘will be’ of identity or of constitution, and (c) whether ‘Q’ is being used as a subject or predicate term. We conclude that this latitude is beneficial, as it conforms with linguistic reality (i.e., the multiple uses actually in place) and also enables one to turn what is ordinarily perceived as a problem for universalist perdurantism viz., a commitment to all sorts of weird and gerrymandered temporally extended entities, into an advantage, for the richness in questions allows us to make sense of.

Ismael aims for an understanding of the nature of an embedded perspective of agents in a world. If successful, this would explain a cluster of ways in which from an embedded perspective, we experience the world in an array of temporally asymmetric ways. Moreover, these are ways that have led many philosophers to rather metaphysically inflationary views about the nature of time, according to which time itself really is dynamical, and is characterized by the movement of an objectively (i.e., non-perspectival) (...) present. Ismael aims to explain these features of our experience without positing any such metaphysical picture. She argues that there are constraints which prevent us from taking this Olympian conception of the world and our place in it, and that these, jointly, explain why we experience the world in these temporally asymmetric ways. We take up two related questions. First, what it would mean to say that these constraints are not merely epistemic, and second, how far these constraints get us in explaining why we experience the world in these ways. (shrink)

Metaphysics is largely an a priori business, albeit a business that is sensitive to the findings of the physical sciences. But sometimes what the physical sciences tell us about our own world underdetermines what we should think about the metaphysics of how things actually are, and even how they could be. This chapter has two aims. The first is to defend a particular conception of the methodology of a priori metaphysics by, in part, exemplifying that methodology and revealing its results. (...) The second is to present a new account of holes. These two aims dovetail nicely. We are independently interested in providing a better analysis of the concept <hole> that yields a more plausible metaphysical story about holes. But focusing on holes is also a good way to explore the methodology we endorse: for this is an area of metaphysics that is sufficiently self-contained and narrow in focus that it provides a manageable case study, while at the same time raising interesting and deep issues about the nature of space. Ultimately we defend a new, functionalist, analysis of holes, which, unlike its rivals, neither misidentifies nor renders us implausibly eliminativist about holes under various different metaphysical suppositions about the nature of space. In the process, we set out the complex relations between the intension of “hole,” and its extension at various worlds under different suppositions about the nature of space. In explicating these relations our account exemplifies what we take to be the core methodology in a priori metaphysics. (shrink)

Harold Noonan has recently argued (2003) that one of Lewis’s (1983: 76– 77) arguments for the view that objects persist by perduring is flawed. Lewis’s argument can be divided into two main sections, the first of which attempts to show that it is possible that there exists a world of temporal parts or stages, and the second, which attempts to show that our world is such a world. Noonan claims that there is a flaw in each of these two stages.We (...) argue to the contrary. (shrink)

This paper proffers an account of why interdisciplinary research on, inter alia, the nature of time can be fruitful even if the disciplines in question have different explanatory pro-jects. We suggest that the special sciences perform a subject setting role for lower-level disciplines such as physics. In essence, they tell us where, amongst a theory of the physical world, we should expect to locate phenomena such as temporality; they tell us what it would take for there to be time. Physical (...) theory tells us whether there is anything like that in the world and what its hidden nature is. Only working in tandem can physics and the special sciences locate and describe the phenomenon that is time. (shrink)

Taylor's project is vastly ambitious. He has touched impressively, though not decisively, on how widely or how narrowly contexts of texts should be defined. It is clear that his construal is very wide indeed, for he has extended the philosopher's canon by including �poietics� as an essential part of understanding the present state of moral thought, but not as holding any special call on us as a morally-driven aesthetic. He also has expanded the historical context by drawing imaginatively from the (...) languages of specific discourses to suggest that these have been languages of moral inquiry reaching their way to the present. Lastly, he has claimed that there need be no necessary conflict between a historical account of the present state of moral philosophy and a strongly held moral position. (shrink)

While deductive validity provides the limiting upper bound for evaluating the strength and quality of inferences, by itself it is an inadequate tool for evaluating arguments, arguing, and argumentation. Similar remarks can be made about rhetorical success and dialectical closure. Then what would count as ideal argumentation? In this paper we introduce the concept of cognitive compathy to point in the direction of one way to answer that question. It is a feature of our argumentation rather than my argument or (...) your argument. In that respect, compathy is like the harmonies achieved by an accomplished choir, the spontaneous coordination of athletic teamwork, or the experience of improvising jazz musicians when they are all in the flow together. It is a characteristic of arguments, not a virtue that can be attributed to individual arguers. It makes argumentation more than just the sum of its individual parts. The concept of cognitive compathy is brought into focus by locating it at the confluence of two lines of thought. First, we work up to the concept of compathy by contrasting it with empathy and sympathy in the context of emotions, which is then transplanted into epistemic, cognitive, and argumentative soil. Second, the concept is analytically linked to ideal argumentation by way of authenticity in communication. In the final section, we explore the extent to which argumentative virtues are conducive to producing compathetic argumentation, but reach the unhappy conclusion that the extra value of compathetic argumentation also transcends the evaluative reach of virtue argumentation theory.

Pragmatism is a distinctive approach to clinical research ethics that can guide bioethicists and members of institutional review boards (IRBs) as they struggle to balance the competing values of promoting medical research and protecting human subjects participating in it. After defining our understanding of pragmatism in the setting of clinical research ethics, we show how a pragmatic approach can provide guidance not only for the day-to-day functioning of the IRB, but also for evaluation of policy standards, such as the one (...) that addresses acceptable risks for healthy children in clinical research trials. We also show how pragmatic considerations might influence the debate about the use of deception in clinical research. Finally, we show how a pragmatic approach, by regarding the promotion of human research and the protection of human subjects as equally important values, helps to break down the false dichotomy between science and ethics in clinical research.

We are grateful to Jongsma et al 1 for their interest in our article analysing the case of ‘Mrs A’, a Dutch woman with Alzheimer’s disease who received euthanasia based on her advance euthanasia directive.2 Their commentary criticises two elements of our analysis. First, the authors believe our reasons for doubting that Mrs A had the capacity to write and revise an AED rely on ‘partial’ empirical data and rest on normative errors. Second, they use two of our statements to (...) suggest we must endorse some implausible claims, for example, that ‘… in all situations and for all people, current well-being should always take precedence over all other values’. Jongsma et al assert: ‘Miller et al argue that people with dementia are impaired to make decisions.’ This casts our probabilistic claim about Mrs A’s capacity as an absolute claim about persons with dementia in general. It also implies we are using an outdated diagnosis-based view of capacity. The accusation then becomes explicit : > … several empirical studies have shown that patients with dementia are able to actively participate in qualitative studies and can respond to open questions in a meaningful way,[2-8] as well that they are able to complete an advance directive in the early phases of dementia.[9, 10] One can therefore not simply conclude on the basis of the diagnosis of dementia ….

The analysis of interacting relativistic many-particle systems provides a theoretical basis for further work in many diverse fields of physics. After a discussion of the nonrelativisticN-particle systems we describe two approaches for obtaining the canonical equations of the corresponding relativistic forms.

On November 8, 1994, Oregon became the first state in the nation to legalize assisted suicide. Passage of Proposition 16 was a milestone in the campaign to make assisted suicide a legal option. The culmination of years of effort, the Oregon vote followed on the heels of failed referenda in California and Washington, and other unsuccessful attempts to enact state laws guaranteeing the right to suicide assistance. Indeed, in 1993, four states passed laws strengthening or clarifying their ban against assisted (...) suicide. No doubt, Proposition 16 is likely to renew the effort to legalize assisted suicide at the state level.The battle over assisted suicide is also unfolding in the courts. Litigation challenging Proposition 16 on the grounds that it violates the equal protection clause is ongoing in Oregon. More significantly, three cases, two in federal courts and one in Michigan state court, have been brought to establish assisted suicide as a constitutionally protected right. (shrink)

This article explores those difficulties in the context of the short but complicated history of Harvard Pilgrim, and its regulatory and competitive environments. The state legislation which made a receivership proceeding possible for Harvard Pilgrim offered some protection for subscribers, but (...) failed to provide the means for achieving a long term solution. The statute merely presented a method for staving off immediate collapse by temporarily protecting the plan from dissolution, and forcing the plan's contracting providers to continue delivering care even if owed money by the plan. The article concludes by drawing lessons for understanding and ideally avoiding similar managed care nearfatalities in the future. (shrink)

This study examined the relationship between individual differences in executive functions (EF; assessed by measures of working memory, Stroop, trail making, and verbal fluency) and ability to down-regulate and up-regulate responses to emotionally evocative film clips. To ensure a wide range of EF, 48 participants with diverse neurodegenerative disorders and 21 older neurologically normal ageing participants were included. Participants were exposed to three different movie clips that were designed to elicit a mix of disgust and amusement. While watching the films (...) they were either instructed to watch, down-regulate, and up-regulate their visible emotional responses. Heart rate and facial behaviours were monitored throughout. Emotion regulatory ability was operationalised as changes in heart rate and facial behaviour in the down- and up-regulation conditions, controlling for responses in the watch condition. Results indicated that higher verbal fluency scores were related to greater ability to regulate emotion in both the down-regulation and up-regulation conditions. This finding remained significant even after controlling for age and general cognitive functioning. No relationships were found between emotion regulation and the other EF measures. We believe these results derive from differences among EF measures, with verbal-fluency performance best capturing the complex sequence of controlled planning, activation, and monitoring required for successful emotion regulation. These findings contribute to our understanding of emotion–cognition interaction, suggesting a link between emotion-regulatory abilities and individual differences in complex executive functions.

At 435c-d and 504b ff., Socrates indicates that there is a "longer and fuller way" that one must take in order to get "the best possible view" of the soul and its virtues. But Plato does not have him take this "longer way." Instead Socrates restricts himself to an indirect indication of its goals by his images of sun, line, and cave and to a programmatic outline of its first phase, the five mathematical studies. Doesn't this pointed restraint function as (...) a provocation, moving us to want to begin the "longer way" and to make use of its conceptual resources to rethink Socrates' images? I begin by finding a double movement in the complex trajectory of the five studies: they both guide the soul in the "turn away from what is coming to be ... [to] what is" (518c) and, at the same time, lead the soul back, albeit in the medium of pure intelligibility, to the sensible world; for the pure figures and ratios that they disclose constitute the core structures of sensible things. I then draw on what Socrates says about geometry and harmonics to address three fundamental questions that he leaves open: the nature of the Good in its responsibility for truth and for the being of the forms; the relations of forms, mathematicals, and sensibles as these are disclosed by dialectic; and the bearing of the philosopher's discovery of the Good on his disposition towards his community and the task of ruling. I close by marking six sets of further questions that these reflections bequeath for dialogues to come. (shrink)

In video games, identification with avatars—virtual entities or characters driven by human behavior—has been shown to serve many interpersonal and intraindividual functions but our understanding of the psychological variables that influence players' avatar choices remains incomplete. The study presented in this paper tested whether players' preferred style of avatar creation is linked to the magnitude of self-perceived discrepancies between who they are, who they aspire to be, and who they think they should be. One-hundred-and-twenty-five undergraduate gamers indicated their preferred avatar (...) creation style and completed a values measure from three different perspectives: their actual, ideal, and ought selves. The average actual/ideal values discrepancy was greater among those who preferred idealized avatars vs. those who preferred realistic avatars. The average actual/ought values discrepancy was greater among those who preferred completely different avatars vs. those who preferred realistic avatars. These results, therefore, offer additional evidence that self-discrepancy theory is a useful framework for understanding avatar preferences. (shrink)

Future-bias is the preference, all else being equal, for negatively valenced events be located in the past rather than the future, and positively valenced ones to be located in the future rather than the past. Strong risk aversion is the preference to pay some cost to mitigate the badness of the worst outcome. People who are both strongly risk averse and future-biased can face a series of choices that will guarantee them more pain, for no compensating benefit: they will be (...) pain pumped. Thus, combining these preferences is rationally impermissible. Dougherty (2011) argues that this gives us reason to think that future-bias is rationally impermissible. This argument, and a similar one presented by Greene and Sullivan (2015), relies on the idea that if several preferences are not rationally combinable, then in the absence of some explanation of why they are not combinable, we should conclude that (at least) one of them is rationally impermissible. We take up this question by, inter alia, reflecting on the empirical results of a study we ran that probes people’s risk averse and future-biased preferences. We argue that the data, in conjunction with other considerations, suggests that we should not infer from the irrationality of the combination of these preferences to the irrationality of one of the preferences singly. We also argue that given the descriptive data about these preferences, there is no reason to think that, if one of them is rationally impermissible, then it is future-bias. (shrink)
