Graham Priest presents an exploration of the development of Buddhist metaphysics, which is viewed through the lens of the catuskoti. In its earliest and simplest form this is a logical/metaphysical principle which says that every claim is true, false, both, or neither; but Priest shows how the principle itself evolves as the metaphysics develops.

A benchmark volume for an emerging field where mental disorders serve as the springboard for philosophical insights.

Graham Priest presents an expanded edition of his exploration of the nature and limits of thought. Embracing contradiction and challenging traditional logic, he engages with issues across philosophical borders, from the historical to the modern, Eastern to Western, continental to analytic.

Teleosemantics seeks to explain meaning and other intentional phenomena in terms of their function in the life of the species. This volume of new essays from an impressive line-up of well-known contributors offers a valuable summary of the current state of the teleosemantics debate.

Most phobias are focussed on a small number of fear-inducing stimuli (e.g., snakes, spiders). A review of the evidence supporting biological and cognitive explanations of this uneven distribution of phobias suggests that the readiness with which such stimuli become associated with aversive outcomes arises from biases in the processing of information about threatening stimuli rather than from phylogenetically based associative predispositions or “biological preparedness.” This cognitive bias, consisting of a heightened expectation of aversive outcomes following fear-relevant stimuli, generates and maintains (...) robust learned associations between them. Some of the features of such stimuli which determine this expectancy bias are estimates of how dangerous they are, the semiotic similarity between them and their aversive outcomes, and the degree of prior fear they elicit. Ontogenetic and cultural factors influence these features of fear-relevant stimuli and are hence important in determining expectancy bias. The available evidence does not exclude the possibility that both expectancy biases and specific evolved predispositions coexist, but the former can explain a number of important findings that the latter cannot.

Recent studies of spider phobia have indicated thatfearof spiders is closely associated with the disease-avoidance response of disgust. It is argued that the disgust-relevant status of the spider resulted from its association with disease and illness in European cultures from the tenth century onward. The development of the association between spiders and illness appears to be linked to the many devastating and inexplicable epidemics that struck Europe from the Middle Ages onwards, when the spider was a suitable displaced target for (...) the anxieties caused by these epidemics. Such factors suggest that the pervasive fear of spiders that is commonly found in many Western societies may have cultural rather than biological origins, and may be restricted to Europeans and their descendants.

The foundations of systematics lie in ontology, not in subjective epistemology. Systems and their elements should be distinguished from classes; only the latter are constructed from similarities. The term classification should be restricted to ordering into classes; ordering according to systematic relations may be called systematization.The theory of organization levels portrays the real world as a hierarchy of open systems, from energy quanta to ecosystems; followingHartmann these systems as extended in time are considered the primary units of reality. Organization levels (...) should be distinguished from levels of differentiation within each organization level.Certain biological systems, such as species, continue to be misinterpreted as classes, particularly by logicians unfamiliar with modern biological theory. Replacement of Aristotelian definitions of species by “polytypic” definitions achieves nothing, because species are individual systems which can be defined from an ontological viewpoint only as wholes. The dispute whether classes are real per se or only in individuals is of no scientific importance; irrespective of which view is taken, any ordering of physical objects into classes constitutes an hypothesis about the structure of the real world.The distinction between essential and contingent characters is relevant only to classification. There are no universal rules for evaluating characters for purposes of systematization. Character statements do not form separate linear sequences. The search for “unit characters” in an absolute sense is futile. All real characters are reducible to relations and are in principle measurable, although there are limitations on the extent to which this can be presently achieved.The concept of the sexual species is fundamental to theories of biosystematics. Sexual species may be defined as lineages consisting at any given time of series of populations between which genetic exchange can occur and delimited in time by two successive processes of speciation. Linnaean nomenclature needs modification; in its traditional form it is appropriate only to non-truncated hierarchies, whereas real phylogenies form truncated hierarchies. In consequence of the distinction between systematization and classification it is concluded that, while taxa may be classified into age classes or evolutionary grades, their limits as taxa can be no different in either case. Classification into evolutionary grades remains an imprecise endeavour, since no general measure of evolutionary differentiation has been devised.The spatial and temporal extent of ecosystems, the postulated basic units of ecosystematics, remains unclarified. Nevertheless there are grounds for expecting progress in this field as the energetic relations between organisms become better understood. Biotic communities are not “abstract” classes, but systematic units. Physiognomic classification should not be confused with systematization of plant communities; both approaches contribute to an understanding of vegetational structure. (shrink)

Are we entitled or justified in taking the word of others at face value? An affirmative answer to this question is associated with the views of Thomas Reid. Recently, C. A. J. Coady has defended a Reidian view in his impressive and influential book. Testimony: A Philosophical Study. His central and most Oliginal argument for his positions involves reflection upon the practice of giving and accepting reports, of making assertions and relying on the word of others. His argument purports to (...) show that testimony is, by its very nature, a “reliable form of evidence about the way the world is.” The argument moves from what we do to why we are justified in doing it. Although I am sympathetic with both the Reidian view and Coady’s attempt to connect why we rely on others with why we are entitled to rely on others, I find Coady’s argument ineffective. (shrink)

Beginning from an earlier claim of mine that there was really no such area of study as the philosophy of sport, Part One of the paper reconsiders the place previously given to David Best’s distinction between purposive sports and aesthetic sports. In light of a famous cricketing event in the 1977 contest between England and Australia (‘The Ashes’), in which Derek Randall turned a cartwheel after taking the winning catch, the paper clarifies that not all aesthetically-pleasing events taking place in (...) sporting competitions can be understood as the aesthetic in sport. Then, in Part Two, the force of the claim that philosophy is one subject is explored. The conclusion is that a focus just on the philosophy of sport is necessarily inappropriate, since it will present the student with only cases from sport to then apply to sport. Rather, one’s understanding must be informed by (much of) the breadth of philosophy. Charles Travis’s view of occasion-sensitivity provides a clear example of appropriately contextual appeal. Part Three of the paper returns to the need for an institutional account of sport, one recognizing that there is no one occasion on which a particular sport is played; and hence no single set of conditions which can uniquely identify that sport. Thus, soccer played with one’s children typically differs from elite soccer: but both are (genuinely) soccer. When one turns to the appreciation of sport (in the light of Stephen Mumford’s excellent Watching Sport: Aesthetics, Ethics and Emotion [2012a]), one recognizes that, in order to genuinely appreciate sport, one cannot detach oneself from the outcome as completely as Mumford’s extreme purist seems to. But reflection on that case may also return us to contextualism by moving us away from attachments to the complete or the exceptionless in our accounts of spectating as of sport: maybe there is no one thing that occurs in all the relevant cases.

The manuscript notes described and trascribed below are unique: they show Bacon in the very act of originating, selecting and developing materials for the natural-philosophical projects of the crucial last years of his life. Many of the notes are drafts of material later incorporated in published texts—notably the Sylva Sylvarum . Examination of the drafts indicates that the Sylva is not a hotch-potch of plagiarized scraps. Bacon took great pains, acknowledged borrowings and drew heavily on his own extensive experimental and (...) observational work. The drafts also show that much of the material was used to display the explanatory power of his ambitious speculative philosophy. Preoccupation with the speculative philosophy is also evidenced in the notes which have no counterpart in the published works. Among these notes is a passage on the size of the universe, the motion of the fixed stars and the hypothesis of the earth's diurnal rotation. In that passage Bacon struggled with threats to his unswervingly geostatic conception of the universe. (shrink)

Among challenges to Molinism, the challenge posed by divine prophecy of human free action has received insufficient attention. We argue that this challenge is a significant addition to the array of challenges that confront Molinism.

Folk psychological realism is the view that folk psychology is true and that people really do have propositional attitudes, whereas anti-realism is the view that folk psychology is false and people really do not have propositional attitudes. We argue that anti-realism is not worthy of acceptance and that realism is eminently worthy of acceptance. However, it is plainly epistemically possible to favor either of two forms of folk realism: scientific or non-scientific. We argue that non-scientific realism, while perhaps unpopular among (...) philosophers of mind, is a distinct form of realism from scientific realism, and that it is not yet knowable whether scientific or non-scientific realism is true. We also outline how adopting realism, but remaining neutral between scientific and non-scientific realism, offers fresh insights into such topics as instrumentalism, supervenience, the language of thought hypothesis, and elimin-ativism.

This paper argues that the non-reductive monist need not be concerned about the ‘problem’ of mental causation; one can accept both the irreducibility of mental properties to physical properties and the causal closure of the physical. More precisely, it is argued that instances of mental properties can be causally efficacious, and that there is no special barrier to seeing mental properties whose instances are causally efficacious as being causally relevant to the effects they help to bring about. It is then (...) shown that the causal relevance of mental properties is consistent with there being no downward causation, so the dilemma of ‘epiphenomenalism or reduction’ can be avoided. Non-reductive monism lives on as a viable position in the philosophy of mind. (shrink)

Too little attention has been paid by philosophers to the cognitive and epistemic dimensions of emotional disturbances such as depression, grief, and anxiety and to the possibility of justification or warrant for such conditions. The chief aim of the present paper is to help to remedy that deficiency with respect to depression. Taxonomy of depression reveals two distinct forms: depression (1) with intentionality and (2) without intentionality. Depression with intentionality can be justified or unjustified, warranted or unwarranted. I argue that (...) the effort of Aaron Beck to show that depressive reasoning is necessarily illogical and distorted is flawed. I identify an essential characteristic of that depression which is a mental illness. Finally, I describe the potential of depression to provide credal contact with important truths. (shrink)

This article proposes a reading of Michel de Certeau’s TheWriting of History which derives an understanding of the concept of practice as authoritative to the establishment and development of Enlightenment rationality. It is seen as a new form of legitimation established in the redeployment of religious ‘formalities’ in early modernity, supportive of the ostensible deliverance of the projects of reason.Subversive of its moral and ideological operations and geneses, this is an understanding of practice whose subject is the state. Practice, as (...) de Certeau advances it, led to the development of a concept of education productive of a regulatory ambit of social utility, and the student as both a figure of the utile and its moral postulate.This article thematizes the authoritative formality of the concept of practice in its hegemonic origins from early modernity to the thought of Karl Marx. It provides a needed supplement to Marx’s still provocative contribution to a persistent counternarrative, one which elides,and thus reinforces, significant prior,and no less persistent, functions of the concept of practice as here elaborated from de Certeau’s TheWriting of History.

The whole of our human experience is determined by certain material conditions which cannot themselves be a part of that experience. In particular there exist objects, inaccessible to our senses, which nevertheless interact with ourselves to produce that experience. But the selves which are so affected by these objects outside our experience, and the internal mechanisms which somehow construct that experience, are also just such material conditions of, and not parts of, that experience. We might describe this appeal to material (...) conditions of experience in Kant's technical terms as the ‘intelligible’ or even ‘transcendental’ background to our empirical experience. In its attempt to provide some explanation, in terms of things in themselves, of empirical objects it forms a central part of what Adickes called Kant's ‘double affection’ theory. (shrink)

This paper asks and examines the question “who are you?” In doing so it embarks across the conceptual terrain of subjectivity, passing through five different regions. First is the subject and otherness, in which are considered Arendtian notions of the “who” of the individual in the appearing world. Next is the relation between the “I” and the “you” in systems of recognition, and how those systems are creations and expressions of social normativity. This is followed by the idea of the (...) sovereignty of the self as a reaction to its dislocation within systems of recognition. Sovereignty as such is viewed through the thought of Jacques Derrida and Hannah Arendt. With Foucault, the authors approach the question of social normativity as a frame rather than a constraint by which the self is stylized. The fourth section of the paper then explores self-questioning as a means of explicit or intentional self-stylization. Contrasting the “mere liberation” of thinking in Arendt’s thought with broader understandings of freedom, the fifth section relates Arendt’s conception of the miraculous with Derrida’s of the event. The paper’s trajectory returns in conclusion to the implications of its course for the initial question of who one is, particularly with respect to the teaching subject. (shrink)

This paper explores the interface between principles of self-applicable truth and classical logic. To this end, the proof-theoretic strength of a number of axiomatic theories of truth over intuitionistic logic is determined. The theories considered correspond to the maximal consistent collections of fifteen truth-theoretic principles as isolated in Leigh and Rathjen.

In 1974, David Best rightly contrasted purposive sports (exemplified by most sports) with aesthetic sports; and recently I was careful to exempt the issues for aesthetic sports from my critique of the prospects for an all-embracing philosophy of officiating. While discretion plays a part in umpiring or refereeing in both kinds of sports, it is especially important for aesthetic sports (such as gymnastic vaulting, ice-skating or diving), where the manner of execution determines victory. Here, it is urged that the issue (...) of objectivity for judgements in aesthetic sports is not the most crucial aspect: we have reason to expect correct accounts from knowledgeable, sensitive and experienced judges or umpires. Impartiality remains a concern, of course, not least between the training for judges or umpires might tend to favour particular styles of performing key movements. So that many past rule-changes are explained as attempts to improve fairness, with competitors getting their ‘just deserts’. In doing so, they have implicitly contributed to what is then valued in the manner of execution in aesthetic sports. The term ‘aesthetic’ is generally applied in its positive valence, although one must recognize the negative valence also. But, for aesthetic sports, the rules provide guidance as to what will or will not be regarded positively in the context of competition. And rule-changes here will sometimes be best explained as attempting to modify what is rewarded in such sports, the manner of performance. Such changes might be expected to bear on the character of the sport (here exemplified through men’s ice-skating). (shrink)

Graham Priest presents an original exploration of philosophical questions concerning the one and the many. He covers a wide range of issues in metaphysics--including unity, identity, grounding, mereology, universals, being, intentionality, and nothingness--and deploys the techniques of paraconsistent logic in order to offer a radically new treatment of unity. Priest brings together traditions of Western and Asian thought that are usually kept separate in academic philosophy: he draws on ideas from Plato, Heidegger, and Nagarjuna, among other philosophers.
