This latest volume of BACAP Proceedings contains some innovative research by international scholars on Plato, Aristotle, and Sophocles. It covers such themes as Plato on the philosopher ruler, and Aristotle on essence and necessity in science. This publication has also been published in paperback, please click here for details.

We present a one per cent measurement of the cosmic distance scale from the detections of the baryon acoustic oscillations in the clustering of galaxies from the Baryon Oscillation Spectroscopic Survey, which is part of the Sloan Digital Sky Survey III. Our results come from the Data Release 11 sample, containing nearly one million galaxies and covering approximately 8500 square degrees and the redshift range 0.2 < z < 0.7. We also compare these results with those from the publicly released (...) DR9 and DR10 samples. Assuming a concordance Λ cold dark matter cosmological model, the DR11 sample covers a volume of 13 Gpc3 and is the largest region of the Universe ever surveyed at this density. We measure the correlation function and power spectrum, including density-field reconstruction of the BAO feature. The acoustic features are detected at a significance of over 7σ in both the correlation function and power spectrum. Fitting for the position of the acoustic features measures the distance relative to the sound horizon at the drag epoch, rd, which has a value of rd,fid = 149.28 Mpc in our fiducial cosmology. We find DV = at z = 0.32 and DV = at z = 0.57. At 1.0 per cent, this latter measure is the most precise distance constraint ever obtained from a galaxy survey. Separating the clustering along and transverse to the line of sight yields measurements at z = 0.57 of DA = and H =. Our measurements of the distance scale are in good agreement with previous BAO measurements and with the predictions from cosmic microwave background data for a spatially flat CDM model with a cosmological constant. © 2014 The Author Published by Oxford University Press on behalf of the Royal Astronomical Society.

Shepherd propounds a theory of mind with a fair claim to be better than Hume’s at explaining the sources of commonly held human beliefs about causal necessity due largely to her relational theory of sense perception. In comparison with Hume’s account, it incorporates a more sophisticated treatment of mental representation, especially the role of relational structure and logical form. Most important, perhaps, Shepherd’s theory enforces the division, obscured by Hume, between the evidence of necessity and the metaphysical foundation of necessity.

In lieu of an abstract, here is a brief excerpt of the content:Reviewed by:Method in Ancient PhilosophyDavid K. GliddenJyl Gentzler, editor. Method in Ancient Philosophy. Oxford: Clarendon Press, 1998. Pp. viii + 398. Cloth, $72.00.The fifteen papers in this collection constitute revisions of conference proceedings and reflect the varied interests of participants. The ensemble exhibits a thoroughly modern methodology. Whatever and however various ancient methods of philosophy may have been, in Anglo-American scholarship it is standard practice to first address established (...) scholarly interpretations as the primary entry point to critical discussionóoften displacing antiquity with a critical vocabulary of philosophical modernity. Scholars may come to understand each other better, but at the risk of asking the wrong questions or sacrificing ancient texts themselves as mere means of producing papers.Most scholars are progressives. They believe philosophy has advanced past the comparatively primitive wisdom of antiquity, and so such scholars feel perfectly entitled to make better sense of ancient texts, by patiently explaining what the ancients would have meant had they only been able to get it right. There are, of course, exceptions. And some papers in this collection suggest deeper faith in our philosophic fathers. So, the battle between the ancients and the moderns is joined once more, between those who would adorn their papers with footnotes for their peers and those who would attempt more anthropological an inquiry into ancient philosophic practices.Ian Mueller and Robert Bolton each address the same passage in Plato's Phaedo, both beginning with an article from Vlastos, first published in 1969. Mueller thoughtfully explores three different yet related accounts of what we might call scientific method in explaining Plato's views on natural change. Bolton wonders whether scholars are asking the wrong questions. Patricia Curd attempts a progressivist account of Eleatic thought, notwithstanding her recognition of the paucity of ancient sources. Complete with elaborately numbered sentences, Gail Fine focuses primarily on Burnyeat (1976) on Plato on Protagoras. Constance Meinwald presents a rather near-sighted account of two passages in the Philebus that employ the peras-apeiron distinction, with a view toward Plato's allegedly modernist mathematization of understanding. Lesley Brown revisits five pages of the Sophist that were hotly debated in the 1960s. With charity and elegance, she offers several plausible solutions to puzzles posed by previous scholars. Sometimes time smoothes over differences.A. A. Long's essay on Plato's presentation of Socrates in the Theaetetus might appear more philosophically anthropological. Yet Long reveals progressive sympathies, suggesting that Plato dispatches Socrates in the Theaetetus, so as to prepare the way for a more rigorously academic form of philosophizing, such as that exhibited in the Sophist. [End Page 111] In this way, Long speculates, Plato abandoned practical ethics for the academic life of research, so familiar to university professors and conference participants. It might be hard to square such speculation with Plato's Laws and the reception of Plato's writings among his own contemporaries. Still, Socrates' shifting role in Plato's dialogues is well worth pondering.By comparison, T. H. Irwin's contribution is wonderfully old-fashioned. His paper addresses the background knowledge to be presumed by ancient readers of Plato's dialogues and how that knowledge is artfully put to use in Plato's depiction of Socrates' reflections on the unity of virtue. By speculating on Plato's relation to his ancient readers, Irwin displaces many modernist preoccupations, though not without himself falling victim to that peculiar scholarly obsession of dating Plato's dialogues by their doctrines.With characteristic conservatism, Gisela Striker cautions scholars not to over-read Aristotle's Prior Analytics. While that extraordinary work may have deep implications for the history of formal logic, it probably was instead intended to be part of a general account of argument. In a similar vein, Charlotte Witt attempts to rescue Aristotle from scholars who would delimit Aristotle's multifarious uses of the "for the sake of" explanation, which altogether pervade his metaphysics, physics, biology and ethics. Yet, Witt soon finds herself competing in a contest over interpretive distinctions, a sport that will certainly never capture Aristotle's own authorial intentions.Facing another mass of scholarship, in this case on Aristotle's dialectic, C. D. C. Reeve sensibly attempts to... (shrink)

This chapter discusses reasons why we have no prospect of knowing whether or not matter thinks. It focuses on the mechanist hypothesis, its purported explanatory scope, and John Locke's commitment to it. The chapter then demonstrates God's immateriality and its implications for the possibility that God has given perception and thought to some material things. It addresses the notion of divine superaddition elaborated in letters to Stillingfleet and considers how thinking, extension, solidity, and motion are connected in case they do (...) coexist in the same substance. The whole difference between Locke and his opponents on the epistemic possibility of thinking matter comes down to this. He maintains, and they deny, that we know the fixed nature of substances of various kinds, a constituent of a substance that determines the powers it necessarily has and those it necessarily lacks.

The epistemological principles underlying randomized, controlled trials and evidence-based medicine generally have not received the attention they require. Broadly speaking, they are the application of work done over several centuries in philosophy and scientific method. The epistemological base is sound, but it also implies internal limitations, having to do with decreasing generality, which particularly affect application to psychological problems. The principles also have nothing to say about values. The question of the 'objective validity' of scientific method is briefly discussed.

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)

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)

El presente texto se interroga sobre los efectos performativos del himno de Chile en cuanto éste designa al país en la forma de una "copia feliz del Edén". A partir de ahí, se pregunta ¿cómo podría una copia afirmarse en la originalidad de una soberanía? Para solucionar la distancia entre copia y original y, por tanto, dar lugar al funcionamiento de la soberanía, el himno designa a esa copia como "feliz". El término "feliz" se constituye, así, en el operador que (...) vendría tanto a apuntalar a la constitución de una soberanía como a revelar el límite de su imposibilidad. "Feliz" permite disminuir la distancia entre copia y original, pero a la vez, la conserva irremediablemente. Por eso, decir que el país es la copia "feliz" es lo mismo que decir "infeliz" toda vez que ambos términos no hacen más que corroborar la diferencia ontológica entre copia y original. Se argumenta que el término "feliz" constituye un dispositivo teológico político, toda vez que replica la función angélica destinada a la administración de la creación divina. En estos términos se pregunta: ¿no será el proyecto de la República de Chile un proyecto esencialmente administrativo? A esta luz, el texto plantea la contraposición entre himno con el poema: el himno -se plantea- constituye el operador angélico que hace posible la articulación de una soberanía. El poema, en cambio, constituiría el resto irreductible que le resiste. This essay asks on the performative efects of the chilean hymn, because it names the country as a "happy copy of Eden". Since this problem, the essay asks: how could the copy may posits as the originality of the sovereignity? To solve the distance between the copy and the original and make posible the sovereignity´s operation, the hymn names the copy as "happy". The word "happy" supports the constitution of the sovereignity and reveals the limit of its own imposibility. "Happy" reduce the distance between the copy and the original but, at the same time, absolutely preserve it. That´s why, say that the country is the "happy" copy is the same than to say that is a "unhappy" one, because both words shows the ontological difference between the copy and the original. This essay argues that the word "happy" is a political theological device because repeats the angelical task of manage the divine creation. In theses terms we ask: ¿Is the chilean republican proyect an administrative one? In this light, the essay posits an aporia between the hymn and poem: the hymn constitutes the angelical operator that makes sovereignity posible, the poem constitutes a singular rest that resist it.

Basado en los trabajos del filósofo italiano G. Agamben, el presente ensayo argumenta que la figura del prudente en Aristóteles constituiría el lugar de la soberanía y, en cuanto tal, tendría un carácter estrictamente biopolítico pues, permite “producir” la humanidad del ser vivo hombre, en cuanto zoon politikón (zoon lógon ekhon). Así, el presente texto da cuenta de una aporía inscrita en el seno de la política occidental y su concepto de justicia que, encarnado en la figura aristotélica del prudente (...) –en cuanto lugar de la decisión soberana- ha de producir la propia “humanidad” del ser vivo hombre, separando, al mismo tiempo, algo así como una nuda vida.

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 volume of essays explores major connected themes in Aristotle's metaphysics, philosophy of nature, and ethics, especially themes related to essence, definition, teleology, activity, potentiality, and the highest good. The volume is united by the belief that all aspects of Aristotle's work need to be studied together if any one of the areas of thought is to be fully understood. Many of the papers were contributions to a conference at the University of Pittsburgh entitled 'Being, Nature, and Life in Aristotle', (...) to honor Professor Allan Gotthelf's many contributions to the field of ancient philosophy; a few are contributions from those who were invited but could not attend. The contributors, all longstanding friends of Professor Gotthelf, are among the most accomplished scholars in the field of ancient philosophy today. (shrink)

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.

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.

This book offers a broad, systematic philosophical approach to mental disorder. The authors spend the first half of the book presenting their basic philosophical allegiances, and they go on to apply their philosophical approach to mental disorder. As the authors note, psychiatry has been largely neglected by contemporary philosophy of mind, and this book is a laudable attempt to rectify the situation by producing a sustained and clinically well-informed philosophical treatment of mental disorder.

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)

It is advisable to treat some sorts of discourse about fiction with the aid of an intensional operator "in such-And-Such fiction...." the operator may appear either explicitly or tacitly.

Putative examples of true contradictions in the social world have been given by dialetheists such as Graham Priest, Richard Routley, and Val Plumwood. However, we feel that it has not been decisively argued that these examples are in fact true contradictions rather than merely apparent. In this paper we adopt a new strategy to show that there are some true contradictions in the social world, and hence that dialetheism is correct. The strategy involves showing that a group of sincere dialetheists (...) can, given an appropriately formed institution, bootstrap contradictions into existence. We discuss objections and consider the implications of this finding for debates over logic. (shrink)

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.

1. The Shmagency Challenge to Constitutivism In metaethics – and indeed, meta-normativity – constitutivism is a family of views that hope to ground normativity in norms, or standards, or motives, or aims that are constitutive of action and agency. And mostly because of the influential work of Christine Korsgaard and David Velleman, constitutivism seems to be gaining grounds in the current literature. The promises of constitutivism are significant. Perhaps chief among them are the hope to provide with some kind (...) of answer to the skeptic about morality or perhaps practical reason, and the hope to secure for practical reason a kind of objectivity that is consistent with its practical, motivationally engaged nature. The former philosophical motivation for constitutivism – most clearly present in much of Korsgaard’s relevant work[1] – relies on the fact that constitutive norms seem to be less mysterious than not-clearly-constitutive norms. There arguably is nothing mysterious about, say, the norms of certain reasonably-well-defined activities, like building a house, or playing chess. And challenges by the relevant skeptic – the one asking "Why should I make sure the house I’m building can shelter people from the weather?" or "Why should I not castle when my king is checked?" – seem very rare, barely intelligible, and anyway remarkably easy to cope with. We should explain to the misguided skeptic that if he doesn’t even try to build something that can protect people from the weather, he’s not in the business of building a house at all; that if she doesn’t even try to play by the rules of chess, she’s not in the business of playing chess at all; and so on. It would be nice, the constitutivist hope seems to go, if we had something equally powerful by way of a response to the skeptic asking "Why be moral?". The other main motivation for constitutivism – most clearly present in David Velleman’s relevant work[2] – starts from a commitment to some rather strong kind of existence-internalism about reasons: An agent has a reason to?, according to such views ), only if she can come to?, or at least to be motivated to?, by sound deliberation starting from her actual motivational set.

Does the capacity to think require the capacity to sense? A lively debate on this topic runs throughout the history of philosophy and now animates discussions of artificial intelligence. Many have argued that AI systems such as large language models cannot think and understand if they lack sensory grounding. I argue that thought does not require sensory grounding: there can be pure thinkers who can think without any sensory capacities. As a result, the absence of sensory grounding does not entail (...) that large language models cannot think or understand. I also consider to what extent quasi-sensory grounding can at least boost the performance of a language model. (shrink)

Dark matter is a fundamental component of the standard cosmological model, but in spite of four decades of increasingly sensitive searches, no-one has yet detected a single dark-matter particle in the laboratory. An alternative cosmological paradigm exists: MOND (Modified Newtonian Dynamics). Observations explained in the standard model by postulating dark matter are explained in MOND by proposing a modification of Newton's laws of motion. Both MOND and the standard model have had successes and failures – but only MOND has repeatedly (...) predicted observational facts in advance of their discovery. In this volume, David Merritt outlines why such predictions are considered by many philosophers of science to be the 'gold standard' when it comes to judging a theory's validity. In a world where the standard model receives most attention, the author applies criteria from the philosophy of science to assess, in a systematic way, the viability of this alternative cosmological paradigm.

Epistemic Evaluation aims to explore and apply a particular methodology in epistemology. The methodology is to consider the point or purpose of our epistemic evaluations, and to pursue epistemological theory in light of such matters. Call this purposeful epistemology. The idea is that considerations about the point and purpose of epistemic evaluation might fruitfully constrain epistemological theory and yield insights for epistemological reflection. Several contributions to this volume explicitly address this general methodology, or some version of it. Others focus on (...) advancing some application of the methodology rather than on theorizing about it. The papers go on to explore the idea that purposes allow one to understand the conceptual demands on knowing, examine how purposeful epistemology might shed light on the debate between internalist and externalist epistemologies, and further develop the idea of purposeful epistemology.

Two models of assertion are described and their epistemological implications considered. The assurance model draws a parallel between the ethical norms surrounding promising and the epistemic norms which facilitate the transmission of testimonial knowledge. This model is rejected in favour of the view that assertion transmits knowledge by expressing belief. I go on to compare the epistemology of testimony with the epistemology of memory.

A familiar interpretation of quantum mechanics (one of a number of views sometimes labeled the "Copenhagen interpretation'"), takes its empirical apparatus at face value, holding that the quantum wave function evolves by the Schrödinger equation except on certain occasions of measurement, when it collapses into a new state according to the Born rule. This interpretation is widely rejected, primarily because it faces the measurement problem: "measurement" is too imprecise for use in a fundamental physical theory. We argue that this is (...) a weak objection, as there may be many ways of making "measurement" precise. However, measurement-collapse interpretations face a more serious objection: a dilemma tied to the quantum Zeno effect. Is measurement itself an observable that can enter superpositions? If yes, then the standard measurement-collapse dynamics is ill-defined. If no, then (at least if measurement is an observable), measurements can never start or finish. The best way out is to deny that measurement is an observable, but this leads to strong and revisionary consequences. This reinforces the view that there is no nonrevisionary interpretation of quantum mechanics. (shrink)
