Bringing between two covers the most influential and accessible articles on Plato's Republic, this collection illuminates what is widely held to be the most important work of Western philosophy and political theory. It will be valuable not only to philosophers, but to political theorists, historians, classicists, literary scholars, and interested general readers.

Zizek Studies: The Greatest Hits (So Far) assembles and presents the best work published in the field of Zizek Studies over the last ten years, providing teachers, students, and researchers with a carefully curated volume of leading-edge scholarship addressing the unique and sometimes eclectic work of Slovenian philosopher and cultural critic Slavoj Zizek. The chapters included in this collection have been rigorously tested in and culled from the (virtual) pages of the International Journal of Zizek Studies, a leading open access (...) journal that began publication in 2007. The book is organized into three sections or subject areas where Zizek and his seemingly indefatigable efforts have had significant impact: philosophy, politics, and popular culture. As a "greatest hits," the book offers the long-time fan and uninitiated newcomer alike a comprehensive overview of the wide range of opportunity in the field of Zizek studies and a remarkable collection of truly interdisciplinary "hits" from a diverse set of innovative and accomplished writers.

Although best known for his contributions to the theory of knowledge, metaphysics, and philosophy of religion, Hume also influenced developments in the philosophy of mind, psychology, ethics, political and economic theory, political and social history, and aesthetic theory. The fifteen essays in this volume address all aspects of Hume's thought. The picture of him that emerges is that of a thinker who, though often critical to the point of scepticism, was nonetheless able to build on that scepticism a constructive, viable, (...) and profoundly important view of the world. Also included in this volume are Hume's two brief autobiographies and a bibliography suited to those beginning their study of Hume. This second edition of one our most popular Companions includes six new essays and a new introduction, and the remaining essays have all been updated or revised. (shrink)

Split brains that result in two simultaneous streams of consciousness cut off from each other are wrongly held to be grounds for doubting the existence of the divinely created soul. The mistake is based on two related errors: first, a failure to appreciate the soul's dependence upon neurological functioning; second, a fallacious belief that if the soul is simple, i.e. without parts, then there must be a unity to its thought, all of its thoughts being potentially accessible to reflection or (...) even unreflective causal interactions. But a soul theorist can allow neurological events to keep some conscious thoughts unavailable to others. (shrink)

We argue that animalism is the only materialist account of personal identity that can account for the autonomy that we typically think of ourselves as possessing. All the rival materialist theories suffer from a moral version of the problem of too many thinkers when they posit a human person that overlaps a numerically distinct human animal. The different persistence conditions of overlapping thinkers will lead them to have interests that conflict, which in many cases prevents them both from autonomously forming (...) and acting on the same intentions. These problems are exacerbated by problems of self-reference plaguing the overlapping thinkers. We contend that the impossibility of simultaneous autonomous action by animals and persons provides a reason to favor animalism over Neo-Lockeanism, Four-Dimensionalism, Constitution theory, and brain-size views of the person. We anticipate and reject arguments that the autonomy of the person and the animal can be shown to be compatible by relying upon either the Parfitian thesis that identity isn’t what matters or claiming that animals acquire the interests of the person they constitute.

Functionalism offers an account of the relations that hold between behavioural functions, information and neural processing, and conscious experience from which one can draw two inferences: for any discriminable difference between qualia there must be an equivalent discriminable difference in function; and for any discriminable functional difference within a behavioural domain associated with qualia, there must be a discriminable difference between qualia. The phenomenon of coloured hearing synaesthesia appears to contradict the second of these inferences. We report data showing that (...) this form of synaesthesia is genuine and probably results from an aberrant projection from cortical language areas to a region specialized for the perception of colour. Since functionalism purports to be a general account of consciousness, one such negative instance, if it can be further sustained empirically, is sufficient to invalidate it. (shrink)

Do our lives have meaning? Should we create more people? Is death bad? Should we commit suicide? Would it be better if we were immortal? Should we be optimistic or pessimistic? Life, Death, and Meaning brings together key readings, primarily by English-speaking philosophers, on such 'big questions.'.

On Zermelo's view, any mathematical theory presupposes a non-empty domain, the elements of which enjoy equal status; furthermore, mathematical axioms must be chosen from among those propositions that reflect the equal status of domain elements. As for which propositions manage to do this, Zermelo's answer is, those that are ?symmetric?, meaning ?invariant under domain permutations?. We argue that symmetry constitutes Zermelo's conceptual analysis of ?general proposition?. Further, although others are commonly associated with the extension of Klein's Erlanger Programme to logic, (...) Zermelo's name has a place in that story. (shrink)

GREGORY R. JOHNSON and DAVID RASMUSSEN argue that Rand's defense of abortion on demand is inconsistent with her own fundamental metaphysical, epistemological, and moral principles, namely that everything that exists has a determinate identity, that the concept of man refers to all of man's characteristics, not just his essential characteristics, and that there is no gap between what an organism truly is and what it ought to be.

Symmetric propositions over domain $\mathfrak{D}$ and signature $\Sigma = \langle R^{n_1}_1, \ldots, R^{n_p}_p \rangle$ are characterized following Zermelo, and a correlation of such propositions with logical type- $\langle \vec{n} \rangle$ quantifiers over $\mathfrak{D}$ is described. Boolean algebras of symmetric propositions over $\mathfrak{D}$ and Σ are shown to be isomorphic to algebras of logical type- $\langle \vec{n} \rangle$ quantifiers over $\mathfrak{D}$. This last result may provide empirical support for Tarski’s claim that logical terms over fixed domain are all and only those (...) invariant under domain permutations. (shrink)

We raise the new possibility that people diagnosed with developmental dyslexia (DD) are specialized in explorative cognitive search, and rather than having a neurocognitive disorder, play an essential role in human adaptation. Most DD research has studied educational difficulties, with theories framing differences in neurocognitive processes as deficits. However, people with DD are also often proposed to have certain strengths – particularly in realms like discovery, invention, and creativity – that deficit-centered theories cannot explain. We investigate whether these strengths reflect (...) an underlying explorative specialization. We re-examine experimental studies in psychology and neuroscience using the framework ofcognitive search, whereby many psychological processes involve a trade-off between exploration and exploitation. We report evidence of an explorative bias in DD-associated cognitive strategies. High DD prevalence and an attendant explorative bias across multiple areas of cognition suggest the existence of explorative specialization. An evolutionary perspective explains the combination of findings and challenges the view that individuals with DD have a disorder. In cooperating groups, individual specialization is favored when features that confer fitness benefits are functionally incompatible. Evidence for search specialization suggests that, as with some other social organisms, humans mediate the exploration–exploitation trade-off by specializing in complementary strategies. The existence of a system of collective cognitive search that emerges through collaboration would help to explain our species’ exceptional adaptiveness. It also aligns with evidence for substantial variability during our evolutionary history and the notion that humans are adapted not to a particular habitat but to variability itself. Specialization creates interdependence and necessitates balancing complementary strategies. Reframing DD therefore underscores the urgency of changing certain cultural practices to ensure we do not inhibit adaptation. Key improvements would remove cultural barriers to exploration and nurture explorative learning in education, academia, and the workplace, as well as emphasize collaboration over competition. Specialization in complementary search abilities represents a meta-adaptation; through collaboration, this likely enables human groups (as a species and as cultural systems) to successfully adapt. Cultural change to support this system of collaborative search may therefore be essential in confronting the challenges humanity now faces. (shrink)

This essay summarizes key insights across the essays in the Hastings Center Report's special report “Time to Rebuild: Essays on Trust in Health Care and Science.” These insights concern trust and trustworthiness as distinct concepts, competence as a necessary but not sufficient input to trust, trust as a reciprocal good, trust as an interpersonal as well as structural phenomena, the ethical impermissibility of seeking to win trust without being trustworthy, building and borrowing trust as distinct strategies, and challenges to trustworthiness (...) posed by the contingent nature of science. Together, these insights stand to advance an area of research that we believe has been historically stymied by conceptual confusion and a long‐standing insistence on treating trust as a purely instrumental good.

Philosophy and Phenomenological Research, EarlyView.

What we call first‐order logic over fixed domain was initiated, in a certain guise, by Peirce around 1885 and championed, albeit in idiosyncratic form, by Zermelo in papers from the 1930s. We characterise such logics model‐ and proof‐theoretically and argue that they constitute exploration of a clearly circumscribed conception of domain‐dependent generality. Whereas a logic, or family of such, can be of interest for any of a variety of reasons, we suggest that one of those reasons might be that said (...) logic fosters some clarification regarding just what qualifies as a logical concept, a logical operation, or a logical law.

This commentary argues against the indictment of current experimental practices such as piecemeal testing, and the proposed integrated experiment design (IED) approach, which we see as yet another attempt at automating scientific thinking. We identify a number of undesirable features of IED that lead us to believe that its broad application will hinder scientific progress.

Gregory R. Johnson and David Rasmussen defend their critique of Ayn Rand's views on abortion, arguing that their critics miss its main points. Tibor Machan and Alexander Tabarrok actually depart from Rand's own position under the guise of defending it; they introduce a non-Randian distinction between being a human organism and being a moral person.

An idea attributable to Russell serves to extend Zermelo’s theory of systems of infinitely long propositions to infinitary relations. Specifically, relations over a given domain \ of individuals will now be identified with propositions over an auxiliary domain \ subsuming \. Three applications of the resulting theory of infinitary relations are presented. First, it is used to reconstruct Zermelo’s original theory of urelements and sets in a manner that achieves most, if not all, of his early aims. Second, the new (...) account of infinitary relations makes possible a concise characterization of parametric definability with respect to a purely relational structure. Finally, based on his foundational philosophy of the primacy of the infinite, Zermelo rejected Gödel’s First Incompleteness Theorem; it is shown that the new theory of infinitary relations can be brought to bear, positively, in that connection as well.

Six experiments investigated variables predicted to influence subjects’ tendency to classify items by a single property instead of overall similarity, following the paradigm of Norenzayan et al., who found that European Americans tended to give more “logical” rule-based responses. However, in five experiments with Mechanical Turk subjects and undergraduates at an American university, we found a consistent preference for similarity-based responding. A sixth experiment with Korean undergraduates revealed an effect of instructions, also reported by Norenzayan et al., in which classification (...) instructions led to majority rule-based responding but similarity instructions led to overall similarity grouping. Our American subjects showed no such difference and used similarity more overall. We conclude that Americans do not have a preference for rule responding in classification and discuss the differences between tasks that reliably show strong rule or unidimensional preferences in contrast to this classification paradigm.

This interview with Charles Taylor explores a central concern throughout his work, viz., his concern to confront the challenges presented by the process of ‘disenchantment’ in the modern world. It focuses especially on what is involved in seeking a kind of ‘re-enchantment.' A key issue that is discussed is the relationship of Taylor’s theism to his effort of seeking re-enchantment. Some other related issues that are explored pertain to questions surrounding Taylor’s argument against the standard secularization thesis (...) that views secularization as a process involving the ineluctable fading away of religion. Additionally, the relationship between Taylor’s religious views and his philosophical work is discussed. (shrink)

The single most important source for Second Temple Jewish exegetical traditions is the three commentaries series written by Philo of Alexandria. Wanting to understand Second Temple Judaism more fully, a group of scholars founded the Philo Institute in 1971 to explore those traditions. The following year they began publication of The Studia Philonica as a venue for their research; however, the significance of Philo's work soon captured the interest of a broader group of scholars and quickly opened the journal's pages (...) up to all aspects of Philonic studies. Six issues were released from 1972-1980 containing twenty-five articles, annual bibliographies, and abstracts of notable publications. The list of contributors is a who's who in Philonic studies in the 1970s and 1980s. After a lapse of almost a decade, the journal was revived as the Studia Philonica Annual, which is devoted to furthering the study of Hellenistic Judaism, in particular the writings and thought of the Hellenistic-Jewish writer Philo of Alexandria (ca. 15 b.c.e. to ca. 50 c.e.). Each year the Annual publishes the most current Philonic scholarship along with an extensive bibliography that is maintained by David Runia. (shrink)

This unique book presents a comprehensive and rigorous treatment of the theory of computability which is introductory yet self-contained. It takes a novel approach by looking at the subject using computation models rather than a limitation orientation, and is the first book of its kind to include software. Accompanying software simulations of almost all computational models are available for use in conjunction with the text, and numerous examples are provided on disk in a user-friendly format. Its applications to computer science (...) itself include interesting links to programming language theory, compiler design theory, and algorithm design. The software, numerous examples, and solutions make this book ideal for self-study by computer scientists and mathematicians alike. (shrink)

An important application of cognitive architectures is to provide human performance models that capture psychological mechanisms in a form that can be “programmed” to predict task performance of human–machine system designs. Although many aspects of human performance have been successfully modeled in this approach, accounting for multitalker speech task performance is a novel problem. This article presents a model for performance in a two-talker task that incorporates concepts from psychoacoustics, in particular, masking effects and stream formation.

In papers published between 1930 and 1935. Zermelo outlines a foundational program, with infinitary logic at its heart, that is intended to (1) secure axiomatic set theory as a foundation for arithmetic and analysis and (2) show that all mathematical propositions are decidable. Zermelo's theory of systems of infinitely long propositions may be termed "Cantorian" in that a logical distinction between open and closed domains plays a signal role. Well-foundedness and strong inaccessibility are used to systematically integrate highly transfinite concepts (...) of demonstrability and existence. Zermelo incompleteness is then the analogue of the Problem of Proper Classes, and the resolution of these two anomalies is similarly analogous. (shrink)

One of the most popular and enduring approaches to indeterminacy phenomena (e.g., vagueness) over the past several decades has been some form or another of supervaluationism. I argue that supervaluationism is inadequate as a model of indeterminacy: There is an entire class of examples of indeterminacy, characterized by a common “branching” structure, that cannot be modeled in the way supervaluationism proposes. I demonstrate my conclusion explicitly with respect to two specific examples—indeterminate personal identity and indeterminate reference—showing how supervaluationism can model (...) neither. Importantly, my arguments apply to both traditional “semantic” and more recent “metaphysical” versions of supervaluationism. (shrink)

In [8], the third author defined a reducibility$\le _w^{\rm{*}}$that lets us compare the computing power of structures of any cardinality. In [6], the first two authors showed that the ordered field of reals${\cal R}$lies strictly above certain related structures. In the present paper, we show that$\left \equiv _w^{\rm{*}}{\cal R}$. More generally, for the weak-looking structure${\cal R}$ℚconsisting of the real numbers with just the ordering and constants naming the rationals, allo-minimal expansions of${\cal R}$ℚare equivalent to${\cal R}$. Using this, we show that (...) for any analytic functionf,$\left \equiv _w^{\rm{*}}{\cal R}$. $is noto-minimal.). (shrink)

With his clear and accessible prose, impeccable scholarship, and balanced Judgment, Roland Teske, SJ, has been an influential and important voice in Medieval philosophy for more than thirty years. This volume, in his honour, brings together more than a dozen essays on central metaphysical and theological themes in Augustine and other medieval thinkers. The authors, listed below, are noted scholars who draw upon Teskes work, reflect on it, go beyond it, and at times even disagree with it, but always in (...) a spirit of respectful co-operation, and always with the aim of getting at the truth. Essays on Augustine contributed by Gerald Bonner, Charles Brittain, Joseph Koterski, SJ, Joseph T. Lienhard, SJ, David Vincent Meconi, SJ, Ann A. Pang-White, Frederick Van Fleteren, Dorothea Weber, and James Wetzel. Essays on Bernard of Clairvaux, William of Auvergne, and other medieval themes contributed by John P. Doyle, William Harmless, SJ, John A. Laumakis, Edward P. Mahoney, and Philipp W. Rosemann. (shrink)

Neo-Fregeanism is a family of positions in the philosophy of mathematics that combines a certain type of platonism about mathematical abstracta with a certain type of logicism about the foundations and epistemology of mathematics. This paper addresses the following question: what sort of theory of reference can/should NF be committed to? The theory of reference I propose for NF comes in two parts. First, an alethic account of referential success: the fact that a term ‘a’ succeeds in referring to something (...) depends on facts about truth. Second, a deflationary account of referential specification: given that ‘a’ refers to something, the fact that ‘a’ refers to b specifically follows from the disquotational schema for reference together with the fact that b = a. In the first section of the paper I argue that NF should be committed to the first part of this theory. This a point on which there is already agreement. The bulk of the paper is therefore devoted to arguing that NF should be committed to the second part, given that it is committed to the first part. I close the paper by indicating some significant implications and a possible problem for this theory of reference. (shrink)

Pancreatitis is a complex, progressively destructive inflammatory disorder. Alcohol was long thought to be the primary causative agent, but genetic contributions have been of interest since the discovery that rare PRSS1, CFTR and SPINK1 variants were associated with pancreatitis risk. We now report two associations at genome-wide significance identified and replicated at PRSS1-PRSS2 and X-linked CLDN2 through a two-stage genome-wide study. The PRSS1 variant likely affects disease susceptibility by altering expression of the primary trypsinogen gene. The CLDN2 risk allele is (...) associated with atypical localization of claudin-2 in pancreatic acinar cells. The homozygous CLDN2 genotype confers the greatest risk, and its alleles interact with alcohol consumption to amplify risk. These results could partially explain the high frequency of alcohol-related pancreatitis in men. © 2012 Nature America, Inc. All rights reserved. (shrink)

This study investigated (1) whether potential future purchasing agents were predisposed to accept gratuities or whether the practice of gratuity acceptance is a manifestation of the job itself, (2) whether the existence of a code of ethics forbidding gratuity acceptance curtails the occurrence, and (3) whether disparities in ethics policies between the sales and purchasing functions affect gratuity acceptance. Hypotheses based upon the concepts of organizational concern and institutionalized ethics are developed and empirically tested. Results suggest that future purchasing agents (...) are predisposed to accept gratuities and that formal written ethics policies decrease the acceptance of gratuities. Disparities in ethics policies between the sales and purchasing functions concerning gratuities failed to affect gratuity acceptance significantly. (shrink)

This essay argues that deflationism is incompatible with the phenomenon of referential indeterminacy. This puts the deflationist in the difficult position of having to deny the possibility of what otherwise seems like a manifest and theoretically important phenomenon. Section 1 provides background on deflationism. Section 2 considers an intuitive argument by Stephen Leeds to the effect that deflationism precludes RI; the essay argues that this argument does not succeed. The rest of the essay presents its own, distinct argument for the (...) incompatibility of deflationism and RI. Section 3 argues that direct RI—RI that is not simply a derivative of some other, nonreferential instance of indeterminacy—is strictly incompatible with deflationism. Section 4 considers a couple of different ways the deflationist might try to achieve indirect RI—via indeterminate identity and indeterminate synonymy—and argues that each is unsatisfactory. (shrink)
