ARISTOTLE’S chapter-long digression in the Peri Hermenias to remark a restriction of the law of the excluded middle has touched off reams of commentary, logical, metaphysical and theological. For the theologian, God’s omniscience and human freedom were each at stake; for the metaphysician, the status of time; and logicians professed to find here an application for their remote exercises in trivalent logics. But whatever be the concern of the commentator, a glance at any one of them is likely to discourage (...) a student from pursuing a question which seems destined only to further entangle itself.

The Theaetetus is subtitled peri epistemes, on knowledge, and peirastikos, tentative. Theaetetus' three attempted definitions of knowledge, each ventured only to fail, are structured in a cascading reduction. This regress functions both negatively, as an indirect demonstration that knowledge is not definable in term of opinion or judgment, that is, knowledge is not "opinion plus," but also positively, as the ill-fated definitions build upon one another to delineate the elements necessary for a possible theory of judgment. The themes of knowledge (...) and judgment never resolve, yet, through the multiple peirastic beginnings that perish struggling to say something lasting about knowledge, this main theme ties together the dialogue's many subthemes-wisdom and character; sophistry and its relation to philosophy; Socrates' trial; intellectual midwifery, or Socratic dialectic; appearance and reality; Heracliteanism; Eleaticism; forms and participation; unity and plurality; particularity and universality; identity and difference; memory and time; relations; the relation of resemblance. One could go on. The guiding question, how to define knowledge, is a theoretical one, and the reasoning becomes progressively more abstract as the dialogue proceeds, while at the same time never straying far from practical implications: the theoretical conception of knowledge holds consequences made manifest in human action and deliberation. The dialogue about knowledge is also a dialogue about wisdom. (shrink)

The anonymous Armenian commentary was transmitted together with the Armenian translation of Aristotle's Peri Hermeneias. It was composed in the Hellenizing style and commonly associated with the figure of David the Invincible, a philosopher of the Neoplatonic School of Alexandria. This article presents a general structural analysis of the commentary followed by a comparative study and translation of its first chapter. It argues that the commentary was indeed written in the tradition of late antique Greek commentaries but was probably (...) not associated with late Neoplatonism. The Armenian commentary shares many common features with Ammonius’ commentary, but also departs from it on many crucial aspects. From a philosophical standpoint, it has much more in common with Boethius’ and Alexander of Aphrodisias’ commentaries than with those of the Neoplatonic School of Alexandria, thus suggesting an early writing date.

Le célèbre incipit du Peri theon (80 B 4 DK = 31 D 10 Laks-Most), dans lequel Protagoras affirmait être dans l’incapacité de savoir si les dieux existent ou non, joue sans aucun doute un rôle important dans l’histoire de l’athéisme ancien dans la mesure où il permet, comme le souligne David Sedley, de reconstruire un contexte culturel dans lequel la négation de l’existence des dieux était considérée comme une thèse philosophique digne d’être discutée. La présente contribution portera sur (...) les principaux problèmes exégétiques relatifs au fragment protagoréen. Dans un premier moment, nous nous occuperons de la question de la constitution du texte. Nous considérerons ensuite l’historicité de la tradition biographique concernant la persécution judiciaire du sophiste, qui est évoquée par la plupart des sources citant le fragment. Finalement, nous essayerons d’étudier le fragment de Protagoras dans le cadre de la tradition philosophique et littéraire qui le précède et de l’analyser à la lumière de la réflexion philosophique du sophiste lui-même, afin de mieux comprendre le point de vue sur les dieux et la religion que Protagoras exprimait dans son écrit.

They reject the correspondence theory, insist truth is anemic, and advance an "anti-theory" of truth that is essentially a collection of platitudes: "Snow is white" is true if and only if snow is white; "Grass is green" is true if and only if grass is green. According to disquotationalists, the only profound insight about truth is that it lacks profundity. David contrasts the correspondence theory with disquotationalism and then develops the latter position in rich detail - more than has (...) been available in previous literature - to show its faults.

In an important departure from theories of causation, David Owens proposes that coincidences have no causes, and that a cause is something which ensures that its effects are no coincidence. In Causes and Coincidences, he elucidates the idea of a coincidence as an event which can be analysed into constituent events, the nomological antecedents of which are independent of each other. He also suggests that causal facts can be analysed in terms of non-causal facts, including relations of necessity. Thus, (...) causation is defined in terms of coincidence, and coincidence without reference to causation. David Owens challenges the ideas associated with Hume, Davidson and Lewis, constructing a theory which distinguishes nomological necessity and sufficiency from their logical counterparts. He is able to offer novel solutions to the major problems of causation, including the direction of causation, the logical form of causal statements, the distinction betwen causal connections and logical connections, and the relationship between psychological and physical causation.

Le Centre de Recherche Philologique de l'Université de Lille III publie ici, dans un premier cahier, quelques études consacrées à l'histoire de l'épicurisme, qui est l'objet d'une des activités principales. Les travaux de ses membres ont en commun d'insister sur l'examen approfondi de la lettre du texte, où nous voyons la condition d'un renouvellement de la compréhension. La critique de la tradition interprétative fait partie de ce réexamen, dont le le lieu privilégié se trouve dans des textes qui, se situant (...) eux-mêmes dans une continuité remarquable, comme le poème de Lucrèce et le mur d'Oenoanda, imposent une réflexion sur les modes de l'actualisation dans le cadre d'une orthodoxie essentielle. Nous sommes heureux de publier en même temps les travaux d'hôtes du Centres et en particulier les dernières découvertes de Martin F. Smith à Oenoanda, qui marquent une nouvelle étape de la connaissance de l'inscription de Diogène. David Sedley qui a présenté à Lille, dans une série de séminaires, les problèmes posés par l'interprétation des papyrus du Péri Phuseôs d'Epicure, reprend ici l'analyse de quelques parties de la Vie de Diogène Laërce, complétant heureusement le commentaire de ce texte par André Laks.

From the author of Wittgenstein's Poker and Would You Kill the Fat Man?, the story of an extraordinary group of philosophers during a dark chapter in Europe's history On June 22, 1936, the philosopher Moritz Schlick was on his way to deliver a lecture at the University of Vienna when Johann Nelböck, a deranged former student of Schlick's, shot him dead on the university steps. Some Austrian newspapers defended the madman, while Nelböck himself argued in court that his onetime teacher (...) had promoted a treacherous Jewish philosophy. David Edmonds traces the rise and fall of the Vienna Circle—an influential group of brilliant thinkers led by Schlick—and of a philosophical movement that sought to do away with metaphysics and pseudoscience in a city darkened by fascism, anti-Semitism, and unreason. The Vienna Circle's members included Otto Neurath, Rudolf Carnap, and the eccentric logician Kurt Gödel. On its fringes were two other philosophical titans of the twentieth century, Ludwig Wittgenstein and Karl Popper. The Circle championed the philosophy of logical empiricism, which held that only two types of propositions have cognitive meaning, those that can be verified through experience and those that are analytically true. For a time, it was the most fashionable movement in philosophy. Yet by the outbreak of World War II, Schlick's group had disbanded and almost all its members had fled. Edmonds reveals why the Austro-fascists and the Nazis saw their philosophy as such a threat. The Murder of Professor Schlick paints an unforgettable portrait of the Vienna Circle and its members while weaving an enthralling narrative set against the backdrop of economic catastrophe and rising extremism in Hitler's Europe.

This is the second of David Pears's acclaimed two‐volume work on the development of Wittgenstein's philosophy, covering the Philosophical Investigations and other writings from 1929 onwards. Though more selective in its coverage than the first volume (it deals mainly with Wittgenstein's philosophy of psychology and the ego, the possibility of a private language and rule‐following), the book reveals with great clarity the style, method, and content of Wittgenstein's later thought. While this volume is independently comprehensible, Pears remains largely within (...) the structural framework of the first volume and uncovers thereby the general overall configuration and internal organization of Wittgenstein's thought.

Supervaluational theories of vagueness have achieved considerable popularity in the past decades, as seen in eg [5], [12]. This popularity is only natural; supervaluations let us retain much of the power and simplicity of classical logic, while avoiding the commitment to strict bivalence that strikes many as implausible. Like many nonclassical logics, the supervaluationist system SP has a natural dual, the subvaluationist system SB, explored in eg [6], [28].1 As is usual for such dual systems, the classical features of SP (...) (typically viewed as benefits) appear in SB in ‘mirror-image’ form, and the nonclassical features of SP (typically viewed as costs) also appear in SB in ‘mirror-image’ form. Given this circumstance, it can be difficult to decide which of two dual systems is better suited for an approach to vagueness.2 The present paper starts from a consideration of these two approaches— the supervaluational and the subvaluational—and argues that neither of them is well-positioned to give a sensible logic for vague language. §2 presents the systems SP and SB and argues against their usefulness. Even if we suppose that the general picture of vague language they are often taken to embody is accurate, we ought not arrive at systems like SP and SB. Instead, such a picture should lead us to truth-functional systems like strong Kleene logic (K3) or its dual LP. §3 presents these systems, and argues that supervaluationist and subvaluationist understandings of language are better captured there; in particular, that a dialetheic approach to vagueness based on the logic LP is a more sensible approach. §4 goes on to consider the phenomenon of higher-order vagueness within an LP-based approach, and §5 closes with a consideration of the sorites argument itself.

Substantive study questions engage with primary texts and encourage students to apply theory to everyday life and common human experiences. The (...) book is accessibly written and flexible enough to fit into any undergraduate or seminary course on ethics. (shrink)

“Aristotle's successor as director of the Lyceum was Theophrastus, his friend and disciple; Eudemus, another of the Stagirite's important disciples should also be mentioned. Other philosophers belonging to the Peripatetic school were: Aristoxenus, Dikaiarchos, Phanias, Straton, Duris, Chamaeleon, Lycon, Hieronymus, Ariston, Critolaus, Phormio, Sotion, Hermippus, Satyrus and others. Straton even succeeded Theophrastus as director of the Lyceum but his name and those of the other Peripatetics of Aristotle's old school should not be considered in a history of logic as they (...) were mainly concerned with history and the natural sciences. Theophrastus rejoiced in an enormous prestige at this time and for long afterwards. Diogenes Laertius attributes a tremendous number of works to him. Of them a significant proportion are writings on logic: Analytica Priora (3 books); Analytica Posteriora (7 books); Analysis of Syllogisms (1 book); Summary of the Analytic s (1 book); Polemic on the Theory of Euristic Arguments. On Definition (1 book); The First Premises (18 books); The Sophisms (2 books); On the Solution of Syllogisms (1 book); Topics (2 books); On Artless Demonstrations (1 book); On Negation (1 book); On Intellect (1 book); Classifications (2 books); On Entymemes (1 book); On the Appreciation of Syllogism (1 book); On Lies and Truth (1 book); Argumentations (2 books); Theses (3 books); On Definition (2 books); On the Data of Problems (1 book); On the Liar (3 books); Preface to the Topics (1 book); On Arguments proper (1 book); Specifications on The Texts of Syllogisms (1 book). Eudemus also wrote some treatises on logic, concerning which some information has come down to us; Ammonius, in his Commentary On Aristotle's Categories attributes to him a writing on The Analytics -- 'Analitika', and another On Expressions -- Peri lexeos, in which he deals with the grammatical and logical functions of the sentence. The commentator David in Prolegomena to Isagoge by Porphiry also mentions these works.. (shrink)

• If we always see b after a, we are justified in thinking b will follow a the next time we see a. • “A hundred instances or experiments on one side, and fifty on another, afford a doubtful expectation of any event; though a hundred uniform experiments, with only one that is contradictory, reasonably beget a pretty strong degree of assurance” (74).

This book uses different perspectives on argumentation to show how we create arguments, test them, attack and defend them, and deploy them effectively to justify beliefs and influence others. David Zarefsky uses a range of contemporary examples to show how arguments work and how they can be put together, beginning with simple individual arguments, and proceeding to the construction and analysis of complex cases incorporating different structures. Special attention is given to evaluating evidence and reasoning, the building blocks of (...) argumentation. Zarefsky provides clear guidelines and tests for different kinds of arguments, as well as exercises that show student readers how to apply theories to arguments in everyday and public life. His comprehensive and integrated approach toward argumentation theory and practice will help readers to become more adept at critically examining everyday arguments as well as constructing arguments that will convince others.

The structure and style of philosophy has evolved in response to philosophy's confrontation with its own limits. Are these limits real or are they just phantoms haunting the philosophical project? How do philosophy and philosophers attempt to overcome these limits, or at least come to terms with them? In "Philosophy at the Limit" David Wood pursues this theme in modern philosophers from Hegel to Derrida including Nietzsche, Wittgenstein, Heidegger and Gadamer. He focuses on questions of philosophical style, problems with (...) dialogue and in direct communication, the structural closure of philosophical texts, and performative strategy in philosophy. "Philosophy at the Limit" is an accessible discussion of some of the complex issues that empower continental philosophy. It may appeal to students of philosophy and contemporary thought at every level, and to the general reader interested in the heart of the current debates in European thought. (shrink)

Ludwig Wittgenstein was born in Vienna in 1889 and died in Cambridge in 1951. He studied engineering, first in Berlin and then in Manchester, and he soon began to ask himself philosophical questions about the foundations of mathematics. What are numbers? What sort of truth does a mathematical equation possess? What is the force of proof in pure mathematics? In order to find the answers to such questions, he went to Cambridge in 1911 to work with Russell, who had just (...) produced in collaboration with Whitehead (1861-1947) Principia Mathematica (1910-1913), a monumental treatise which bases mathematics on logic. But on what is logic based? Wittgenstein's attempt to answer this question convinced Russell that he was a genius. During the 1914-8 war he served in the Austrian army and in spare moments continued the work on the foundations of logic which he had begun in 1912. His war-time journal, Notebook s 1914-16 (1961), reveals the development of his ideas more clearly that the final version, Tractatus Logico- Philosophicus, which he published in the early 1920s.

"Infectious Nietzsche is simply one of the most interesting and engaging works to appear on Nietzsche’s philosophy in years." —David Allison Krell explores health, illness, and creativity in the life and thought of Friedrich Nietzsche. Drawing on a varied literature of philosophical reflections on health, and analyzing Nietzsche’s confrontation with traditional values, Krell skillfully engages the legacy of Platonism and Western metaphysics that is at the core of Nietzsche’s thought. Nietzsche’s genealogical critique, his doctrine of eternal recurrence of the (...) same, and the Nietzschean physiology and psychology of decadence are principal foci. Anyone interested in a philosophical reflection on questions of genius and pathology, and all readers of Nietzsche, will find Krell’s new book compelling reading. (shrink)

The goal of cladistic systematics is to discern sister-group relations (cladistic relations) by the methods of cladistic analysis and to represent them explicitly and unambiguously in cladograms and cladistic classifications. Cladists have selected cladistic relations to represent for two reasons: cladistic relations can be discerned with reasonable certainty by the methods of cladistic analysis and they can be represented with relative ease in cladograms and classifications. Cladists argue that features of phylogeny other than cladistic relations cannot be discerned with sufficient (...) certainty to warrant attempting to represent them in either cladograms or classifications and could not be represented if they could. I argue that a better alternative is to work toward improving methods of cladistic analysis (or else to supplement them with other methods) so that such features of phylogeny can be discerned and to devise methods of representation capable of representing them in both cladograms and classifications. However, cladograms and classifications cannot represent everything about phylogeny. It is better to represent one or two aspects of phylogeny explicitly and unambiguously than nothing at all.

Jared Diamond and other leading scholars have argued that the domestication of animals for food, labor, and tools of war has advanced the development of human society. But by comparing practices of animal exploitation for food and resources in different societies over time, David A. Nibert reaches a strikingly different conclusion. He finds in the domestication of animals, which he renames "domesecration," a perversion of human ethics, the development of large-scale acts of violence, disastrous patterns of destruction, and growth-curbing (...) epidemics of infectious disease. Nibert centers his study on nomadic pastoralism and the development of commercial ranching, a practice that has been largely controlled by elite groups and expanded with the rise of capitalism. Beginning with the pastoral societies of the Eurasian steppe and continuing through to the exportation of Western, meat-centered eating habits throughout today's world, Nibert connects the domesecration of animals to violence, invasion, extermination, displacement, enslavement, repression, pandemic chronic disease, and hunger. In his view, conquest and subjugation were the results of the need to appropriate land and water to maintain large groups of animals, and the gross amassing of military power has its roots in the economic benefits of the exploitation, exchange, and sale of animals. Deadly zoonotic diseases, Nibert shows, have accompanied violent developments throughout history, laying waste to whole cities, societies, and civilizations. His most powerful insight situates the domesecration of animals as a precondition for the oppression of human populations, particularly indigenous peoples, an injustice impossible to rectify while the material interests of the elite are inextricably linked to the exploitation of animals. Nibert links domesecration to some of the most critical issues facing the world today, including the depletion of fresh water, topsoil, and oil reserves; global warming; and world hunger, and he reviews the U.S. government's military response to the inevitable crises of an overheated, hungry, resource-depleted world. Most animal-advocacy campaigns reinforce current oppressive practices, Nibert argues. Instead, he suggests reforms that challenge the legitimacy of both domesecration and capitalism. (shrink)

This is the best overview of Foucault's work to date. A principal architect of poststructuralism, Michel Foucault reshaped the varied disciplines of history, philosophy, literary theory, and social science. David Shumway has provided, for the nonspecialist, a systematic analysis of the works of Foucault that is both thorough and accessible. Shumway connects Foucault's various conceptual and linguistic techniques to the basic critical strategies and purpose of his philosophy.

Evolution is frequently concentrated in bursts of rapid morphological change and speciation followed by long‐term stasis. We propose that this pattern of punctuated equilibria results from an evolutionary tug‐of‐war between host genomes and transposable elements (TEs) mediated through the epigenome. According to this hypothesis, epigenetic regulatory mechanisms (RNA interference, DNA methylation and histone modifications) maintain stasis by suppressing TE mobilization. However, physiological stress, induced by climate change or invasion of new habitats, disrupts epigenetic regulation and unleashes TEs. With their capacity (...) to drive non‐adaptive host evolution, mobilized TEs can restructure the genome and displace populations from adaptive peaks, thus providing an escape from stasis and generating genetic innovations required for rapid diversification. This “epi‐transposon hypothesis” can not only explain macroevolutionary tempo and mode, but may also resolve other long‐standing controversies, such as Wright's shifting balance theory, Mayr's peripheral isolates model, and McClintock's view of genome restructuring as an adaptive response to challenge.

Several analyses of biological function — for example, those of Williams, Millikan, and Kitcher — identify an item’s function with what natural selection designed it to do. Allen and Bekoff have disagreed, claiming that natural design is a special case of biological function. I argue that Allen and Bekoff’s account of natural design is unduly restrictive and that it fails to mark a principled distinction between function and design. I distinguish two approaches to the phenomenon of natural design — the (...) “trait-centered” approach of Allen and Bekoff and the “organism-centered” approach — and defend the latter. When design is understood according to the organism-centered approach, biological function and design are co-instantiated phenomena. (shrink)

Examining the significance of Kant's account of "rational faith," this study argues that he profoundly revises his account of the human will and the moral philosophy of it in his later religious writings.

The last one hundred years has seen unimaginable technological progress transforming every aspect of human life. Yet we seem unable to shake a profound unease with the direction of modern technology and its ideological siblings, global capitalism and massive consumption. Philosophers such as Marcuse, Borgmann and especially Heidegger, have developed important analyses of technological society, however in this book David Lewin argues that their ideas have remained limited either by their secular context, or by the narrow conception of religion (...) that they do allow. This study guides the reader along the newly formed paths of the philosophy of technology, arguing that where those paths come to an abrupt end, a religious discourse is needed to articulate the ultimate concerns that drive technological action. It calls for a meditation on the central insight of many religious traditions that, in an ultimate sense, we 'know not what we do.' To acknowledge that we know not what we do is the first step towards a theology of technology that draws upon insights from the mystical theological tradition, as well as from recent developments in the continental philosophy of religion.

David Kelley discusses the relationship between philosophy and sense of life and explains why he and William Thomas do not consider sense of life essential to the explanation of why art is a major human value, though it is essential to explaining how people create and experience art.

In this book, I offer an account of intentional action. The book has two main parts: in the first part, I discuss and criticize the currently prevailing account of intentional action—the Causal Theory of Action (CTA)—and, in the second part, I offer my alternative account. The CTA proposes essentially two conditions for something that you do to be an intentional action: (1) what you do is represented by your intention (or other mental attitudes), and (2) it is caused by your (...) intention. Against the CTA, I argue that, since it conceives of representation and causality as essentially separate conditions, it cannot explain why, when someone acts intentionally, it is not a mere accident that both conditions are jointly satisfied: i.e., that the intention causes the movement it represents. The CTA’s inability to rule out such accidentality is, as I argue further, the deeper source of the notorious problem of deviant causation. Given this diagnosis, I claim that the key for a satisfactory account of intentional action is to conceive of the essential unity of representation and causality in intentional action. Doing so, I suggest, requires understanding a distinctive sort of causality at work in intentional action. Following the work of G.E.M. Anscombe, I argue that what is distinctive of the sort of causal-explanatory connection captured in action explanations like “S is doing A because she intends to do B” is that it is essentially known by the acting subject. In the final sections of the book, I then develop and defend a conception of the sort of self-knowledge involved in intentional action. (shrink)

Hand's End offers a new philosophy of technology as the fundamental way in which humans experience and define nature―the tool as humanity extended.

In “Freedom and Resentment,” P. F. Strawson argues that the “profound opposition” between the objective and reactive stances is quite compatible with our rationally retaining the latter as important elements in a recognizably human life. Unless he can establish this, he has no hope of establishing his version of compatibilism in the free will debate. But, because objectivity is associated so intimately with the rationally conducted explanation of action, it is not clear how the opposition of these stances is compatible (...) with the rationality of the reactive attitudes. More to the point, it is not clear how an intellectual activity like shifting from the reactive to the objective stance can dispel reactive attitudes without thereby also rationally disqualifying them. I solve this puzzle by drawing on the idea that one cognitive component of emotions is the rationally optional “shift of attention.” a feature which in turn helps to explain a lot about the role reactive emotions can play in the fixation of belief.

This book discusses the development of Edward Tolman's purposive behaviourism from the 1920s to the 1950s, highlighting the tension between his references to cognitive processes and the dominant behaviourist trends. It shows how Tolman incorporated concepts from European scholars, including Egon Brunswik and the Gestalt psychologists, to justify a more purposive form of behaviourism and how the theory evolved in response to the criticisms of his contemporaries. The manuscript also discusses Tolman's political activities, culminating in his role in the California (...) loyalty oath controversy in the 1950s. Tolman was involved in a number of progressive causes during his lifetime, activities that drew the attention of both state legislators in California and the Federal Bureau of Investigation. It treats Tolman's theoretical and political activities as emanating from the same source, a desire to understand the learning process in a scientific manner and to apply these concepts to improve the human condition.
