This Thesis engages with contemporary philosophical controversies about the nature of dispositional properties or powers and the relationship they have to their non-dispositional counterparts. The focus concerns fundamentality. In particular, I seek to answer the question, ‘What fundamental properties suffice to account for the manifest world?’ The answer I defend is that fundamental categorical properties need not be invoked in order to derive a viable explanation for the manifest world. My stance is a field-theoretic view which describes the world as (...) a single system comprised of pure power, and involves the further contention that ‘pure power’ should not be interpreted as ‘purely dispositional’, if dispositionality means potentiality, possibility or otherwise unmanifested power or ability bestowed upon some bearer. The theoretical positions examined include David Armstrong’s Categoricalism, Sydney Shoemaker’s Causal Theory of Properties, Brian Ellis’s New Essentialism, Ullin Place’s Conceptualism, Charles Martin’s and John Heil’s Identity Theory of Properties and Rom Harré’s Theory of Causal Powers. The central concern of this Thesis is to examine reasons for holding a pure-power theory, and to defend such a stance. This involves two tasks. The first requires explaining what plays the substance role in a pure-power world. This Thesis argues that fundamental power, although not categorical, can be considered ontologically-robust and thus able to fulfil the substance role. A second task—answering the challenge put forward by Richard Swinburne and thereafter replicated in various neo-Swinburne arguments—concerns how the manifestly qualitative world can be explained starting from a pure-power base. The Light-like Network Account is put forward in an attempt to show how the manifest world can be derived from fundamental pure power. (shrink)

In this article, drawing on the discursive psychology of Rom Harré, we show how mapping the exchange of words among people might disclose a complex reality; not merely that which farmers explicitly talk ‘about’ but the reality implicitly at stake within the communication. More specifically, we show how discourses involving modern farmers reveal an underlying placing in an abstract space, having sub-spaces defined by the life-orientation, sense of self and according self-positioning of modern people. In this way, we construct a (...) road map of a set of ‘individualities’ characterizing the life of modern farmers: an individuality of citizenship, an individuality of geographies and an individuality of experience. Consequently, farmers face the problem that this multiplicity of individuality prevents them from communicating, as we will call it, univocally in the public by contrast to the univocal voices of other established social groups. We will analyse the structure of that problem by viewing diverse relations between the authority and the authenticity of different partners in the conversation on land use. (shrink)

Quantum field theory, one of the most rapidly developing areas of contemporary physics, is full of problems of great theoretical and philosophical interest. This collection of essays is the first systematic exploration of the nature and implications of quantum field theory. The contributors discuss quantum field theory from a wide variety of standpoints, exploring in detail its mathematical structure and metaphysical and methodological implications.

Proponents of the view that social structures are ontologically distinct from the people in whose actions they are immanent have assumed that structures can stand in causal relations to individual practices. Were causality to be no more than Humean concomitance correlations between structure and practices would be unproblematic. But two prominent advocates of the ontological account of structures, Bhaskar and Giddens, have also espoused a powers theory of causality. According to that theory causation is brought about by the activity of (...) particulars, in the social psychological case, individuals of some sort. Consistence would demand that structure be those individuals. But neither Giddens nor Bhaskar wish to reify structure to the extent that would fit it for a role as a powerful particular. If only human beings can be powerful particulars in these contexts, the only way that structures can be real must be as properties of conversational interactions. Human action is social just in so far as people direct themselves to engage well in joint activities with others. (shrink)

The Nature of God explores a perennial problem in the philosophy of religion.

Reason and Value collects 15 new papers by leading contemporary philosophers on themes from the work of Joseph Raz. Raz has made major contributions in a wide range of areas, including jurisprudence, political philosophy, and the theory of practical reason; but all of his work displays a deep engagement with central themes in moral philosophy. The subtlety and power of Raz's reflections on ethical topics make his writings a fertile source for anyone working in this area. Especially significant are his (...) explorations of the connections between practical reason and the theory of value, which constitute a sustained and penetrating treatment of a set of issues at the very center of moral philosophy as it is practiced today. The contributors to the volume acknowledge the importance of Raz's contributions by engaging critically with his positions and offering independent perspectives on the topics that he has addressed. The volume aims both to honour Raz's accomplishments in the area of ethical theorizing, and to contribute to an enhanced appreciation of the significance of his work for the subject. (shrink)

Body care has never before been so much a focus of public interest, nor have the ways we classify people by reference to their kind of body excited such political passions. This study is an attempt to build a comprehensive account of the roles our bodies play in our lives. Through a series of discussions Rome harre concludes that the roles the body plays in our lives are determined less by organic functioning than by cultural conventions and social meanings.

How do we access the authentic self in order to live fulfilling, meaningful lives? In straightforward terms, The Heart of the Matter: Gifts in Strange Wrapping Paper explains a simple but extraordinarily powerful technique called the See, Feel, Hear Challenge that enables people to easily gain entry into the storehouse of their subconscious core beliefs. In the process, it cracks the coded messages that those beliefs release in the form of disease, suffering, addictions, unhappy relationships, and victimized circumstances. Based in (...) the latest findings in neuroscience and neurocardiology, this book guides readers to an uncomplicated understanding of the astounding power of our emotions and how life automatically delivers experiences that trigger negative reactions that subconsciously impact us. These emotions form the foundation of core beliefs that create unhealthy attitudes and dis-ease patterns that keep us from experiencing the authentic, satisfying lives we desire. Using clear examples and true stories from clients, Dr. Weissman’s latest work demonstrates how we can release these stored emotions and their wisdom via the See, Feel, Hear Challenge. It then explains how to use this simple method to evoke feelings that positively impact the quantum field, remolding our bodies, minds, and everyday lives into purposeful expressions of inner joy and radiant well-being. Whether you’re dealing with addictions, dysfunctional relationships, or illness, or are focused on becoming an Olympic champion, The Heart of the Matter gives you a potent tool for positive change and transformation that you can use for the rest of your life.

Elliot R. Wolfson intervenes in the debate over Martin Heidegger and Nazism from a unique perspective, as a scholar of Jewish mysticism and philosophy who has been profoundly influenced by Heidegger's work. He reveals crucial aspects of Heidegger's thinking that betray an affinity with dimensions of Jewish thought.

Individuals with trypophobia have an aversion towards clusters of roughly circular shapes, such as those on a sponge or the bubbles on a cup of coffee. It is unclear why the condition exists, given the harmless nature of typical eliciting stimuli. We suggest that aversion to clusters is an evolutionarily prepared response towards a class of stimuli that resemble cues to the presence of parasites and infectious disease. Trypophobia may be an exaggerated and overgeneralised version of this normally adaptive response. (...) Consistent with this explanation, individuals with trypophobia, as well as comparison individuals, reported aversion towards disease-relevant cluster stimuli, but only the trypophobic group reported aversion towards objectively harmless cluster stimuli that had no relevance to disease. For both groups the level of aversion reported was predicted uniquely by a measure of disgust sensitivity. Scaled emotion ratings and open-ended responses revealed that the aversive response was predominantly based on the disease avoidance emotion, disgust. Many open-ended responses also described skin sensations. These findings support the proposal that individuals with trypophobia primarily perceive cluster stimuli as cues to ectoparasites and skin-transmitted pathogens. (shrink)

This book focuses upon the perennial question of the existence and nature of an obligation to obey the law. Leading writers have, at one time or another, emphasized considerations such as gratitude, 'divine ordering, ' prudence, contract, autonomy, and utility in seeking to justify, or to deny any justification for, some sort of obligation to obey the positive law. The book provides relevant selections from a sampling of the historical approaches to legal obligation taken by writers such as Plato, Augustine, (...) Aquinas, Hobbes, Locke, Hume, Rousseau, Thoreau, Bentham, Marx and Engels, and Martin Luther King, Jr. These classical discussions are augmented by critical questions and commentary, by independent discussions of the question of legal obligation by a wide range of contemporary writers, and by relevant judicial cases discussing matters such as conscientious objection and civil disobedience.

The concept of yinyang lies at the heart of Chinese thought and culture. The relationship between these two opposing, yet mutually dependent, forces is symbolized in the familiar black and white symbol that has become an icon in popular culture across the world. The real significance of yinyang is, however, more complex and subtle. This brilliant and comprehensive analysis by one of the leading authorities in the field captures the richness and multiplicity of the meanings and applications of yinyang, including (...) its visual presentations. Through a vast range of historical and textual sources, the book examines the scope and role of yinyang, the philosophical significance of its various layers of meanings and its relation to numerous schools and traditions within Chinese philosophy. By putting yinyang on a secure and clear philosophical footing, the book roots the concept in the original Chinese idiom, distancing it from Western assumptions, frameworks and terms, yet also seeking to connect its analysis to shared cross-cultural philosophical concerns.

Information can be public among a group. Whether or not information is public matters, for example, for accounts of interdependent rational choice, of communication, and of joint intention. A standard analysis of public information identifies it with (some variant of) common belief. The latter notion is stipulatively defined as an infinite conjunction: for p to be commonly believed is for it to believed by all members of a group, for all members to believe that all members believe it, and so (...) forth. This analysis is often presupposed without much argument in philosophy. Theoretical entrenchment or intuitions about cases might give some traction on the question, but give little insight about why the identification holds, if it does. The strategy of this paper is to characterize a practical-normative role for information being public, and show that the only things that play that role are (variants of) common belief as stipulatively characterized. In more detail: a functional role for “taking a proposition for granted” in non-isolated decision making is characterized. I then present some minimal conditions under which such an attitude is correctly held. The key assumption links this attitude to beliefs about what is public. From minimal a priori principles, we can argue that a proposition being public among a group entails common commitment to believe among that group. Later sections explore partial converses to this result, the factivity of publicity and publicity from the perspective of outsiders to the group, and objections to the aprioricity of the result deriving from a posteriori existential presuppositions.

In lieu of an abstract, here is a brief excerpt of the content:Commentary on “Non-Cartesian Frameworks”Rom Harré (bio)There are three points in Dr. Berger’s paper that seem to me to call for immediate comment:1. There is the familiar (but in Berger’s case, only a partial) misunderstanding of the upshot of the third phase of Wittgenstein’s private-language argument. Having shown that expressive and descriptive discourse are radically different, and that expressive discourse can be learned only in contexts of action in which (...) there are natural expressions of personal feeling, experience, and so on, Wittgenstein goes on to show that whatever furnishes the mind, it is not thing-like. He does this by showing that “sameness” of thoughts and feelings cannot be spelled out in the same terms as sameness of things, that is, in terms of numerical and qualitative identity. Yet there is a proper use for the concept of sameness of thoughts and feelings. It is to be found in the role that expressions of feelings and declarations of thoughts play in the language games that constitute a form of life. There is no “unresolved tension,” as Berger seems to think. Although pains are not thing-like, they do have a location, do endure, and do differ from one another.The introduction of the powerful expressive/descriptive distinction is the key to the fallacies of representationalism. Expressive acts do not represent but descriptive acts might. But we can draw on the demonstration that mental “somethings” are not thing-like to eliminate that possibility. The root of representationalism is the seventeenth-century conception of the mind as a container of mental entities: ideas. Ideas are to psychology what atoms are to physics. According to Hume, ideas are copies of impressions. In that disastrous thesis, representationalism was born, as a generalization of Locke’s grounding principle that the ideas of primary qualities resembled primary qualities. The cure for this complex mesh of mistakes must be deeply philosophical. It must not be confined to easy criticisms of Locke’s resemblance doctrine, not yet to more subtle Berkleyan strictures on the supposed distinction between ideas and qualities. It must cut at the very deepest assumption of representationalism—that there are mental entities. And on that matter, Wittgenstein’s analysis will, one hopes, prove to be final.2. With representationalism cast onto the midden of history, what account are we to give of mentation? In a sense, Wittgenstein’s insights abolish the inner/outer distinction, an offshoot of the concept of the container-mind. But they leave standing the distinction between what is done privately and what is done publicly. Yet these domains must be of the same nature, since in the expressive use of signs, we find a holism encompassing what we feel and our disposition to express it. Linguistic substitutes for natural forms [End Page 185] of expression must share that holism. But there are no natural expressions of propositional thoughts. Why? Because we are capable of private propositional thinking just insofar as we have mastered public uses of the instruments of propositional thought. These instruments are cultural products.The practice of psychotherapy can be nothing other than discursive. The quotations concerning praxis that Berger offers are disconcertingly vague. To add, as Berger does, that we must take theory into account does not cure the vagueness. We do not know what Berger takes theory to be, only that it is not theory as physicists have it; i.e., systems of hypotheses about hidden processes which bring about that which can be observed. Following Wittgenstein one step farther, we can say that the only thing that could be theory-like in the enterprises of psychotherapists would be grammars. Grammars express the often unformulated norms of discourses. Psychoanalytic theories could then be addressed as expressions of the norms of certain kinds of discourses. Incorporating a “theory” would then be nothing but determining to adopt a certain grammar in one’s therapeutic discourses. Freed of the idea that one of some set of theories must be true and preferred to all others, one is free to adopt and adapt grammars to occasions. Some grammars are tied to natural expressions and so to the ethology of the human form of life... (shrink)

In lieu of an abstract, here is a brief excerpt of the content:Philosophy, Psychiatry, & Psychology 11.1 (2004) vii [Access article in PDF] In Memoriam:Kathy Wilkes Rom Harré Everyone in the community of those with a serious interest in the philosophy of psychology will have been deeply saddened by the premature of death of Kathy Wilkes a few weeks ago.Kathy spent most of her academic life proper as a Fellow and Tutor at St Hilda's, the last remaining bastion of single-sex (...) education in Oxford. She was a devoted teacher and, until her last few years, a presence in the then Philosophy Subfaculty. Her elegant little book on Physicalism, is still available from Amazon.com, after more than 20 years, a tribute to its enduring qualities. Her Real People is already a classic of philosophical psychopathology. Her last major project was the editing of a collection of papers on cognitive psychology with Bill Newton-Smith.Kathy was among a group of mainly Oxford people who were drawn into an effort to bring analytical philosophy to Eastern Europe, through the half-open door of the International University Centre in Dubrovnik. Although most of us made sporadic visits and scuttled off home when our courses were done, Kathy's involvement was deep and passionate. She stayed through the siege of Dubrovnik, throwing herself into humanitarian efforts without any thought of the consequences for herself. They were indeed serious, and I think it fair to say that she never fully recovered her health from the ordeal.Kathy was very good at bringing a kind of generous clarity to her philosophical work. This generosity of spirit took her to the re-opening of the Philosophy Summer School in Beijing, again largely an Oxford effort. This was the last time I spent any considerable time in her company, when she was able to bring that intellectual virtue I called generous clarity to inspire all of those teaching in the school.She was an enthusiast, and her brand of enlightened but skeptical scholarship will be greatly missed....

R. Jay Wallace argues in this book that moral accountability hinges on questions of fairness: When is it fair to hold people morally responsible for what they do? Would it be fair to do so even in a deterministic world? To answer these questions, we need to understand what we are doing when we hold people morally responsible, a stance that Wallace connects with a central class of moral sentiments, those of resentment, indignation, and guilt. To hold someone responsible, he (...) argues, is to be subject to these reactive emotions in one's dealings with that person. Developing this theme with unusual sophistication, he offers a new interpretation of the reactive emotions and traces their role in our practices of blame and moral sanction. With this account in place, Wallace advances a powerful and sustained argument against the common view that accountability requires freedom of will. Instead, he maintains, the fairness of holding people responsible depends on their rational competence: the power to grasp moral reasons and to control their behavior accordingly. He shows how these forms of rational competence are compatible with determinism. At the same time, giving serious consideration to incompatibilist concerns, Wallace develops a compelling diagnosis of the common assumption that freedom is necessary for responsibility. Rigorously argued, eminently readable, this book touches on issues of broad concern to philosophers, legal theorists, political scientists, and anyone with an interest in the nature and limits of responsibility.

Artificial intelligence, the "science and engineering of intelligent machines", still has yet to create even a simple "Advice Taker" [McCarthy, 1959]. We have previously argued [Waser, 2011] that this is because researchers are focused on problem-solving or the rigorous analysis of intelligence (or arguments about consciousness) rather than the creation of a "self" that can "learn" to be intelligent. Therefore, following expert advice on the nature of self [Llinas, 2001; Hofstadter, 2007; Damasio, 2010], we embarked upon an effort to design (...) and implement a self-understanding, self-improving loop as the totality of a (seed) AI. As part of that, we decided to follow up on Richard Dawkins' [1976] speculation that "perhaps consciousness arises when the brain's simulation of the world becomes so complete that it must include a model of itself" by defining a number of axioms and following them through to their logical conclusions. The results combined with an enactive approach yielded many surprising and useful implications for further understanding consciousness, self, and "free-will" that continue to pave the way towards the creation of safe/moral autopoiesis.

Count Me In (CMI) was launched in 2015 as a patient-driven research initiative aimed at accelerating the study of cancer genomics through direct participant engagement, electronic consent and open-access data sharing. It is an example of a large-scale direct-to-patient (DTP) research project which has since enrolled thousands of individuals. Within the broad scope of ‘citizen science’, DTP genomics research is defined here as a specific form of ‘top-down’ research endeavour developed and overseen by institutions within the traditional human subjects research (...) context; in novel ways, it engages and recruits patients with defined diseases, consents them for medical information and biospecimens sharing, and stores and disseminates genomic information. Importantly, these projects simultaneously aim to empower participants in the research process while increasing sample size, particularly in rare disease states. Using CMI as a case study, this paper discusses how DTP genomics research raises new questions in the context of traditional human subjects research ethics, including issues surrounding participant selection, remote consent, privacy and return of results. It aims to demonstrate how current research ethics frameworks may be insufficient in this context, and that institutions, institutional review boards and investigators should be aware of these gaps and their role in ensuring the conduct of ethical, novel forms of research together with participants. Ultimately, a broader question is raised of whether the rhetoric of participatory genomics research advocates for an ethic of personal and social duty for contributing to the advancement of generalisable knowledge about health and disease.

The young Hegel was entranced by the notion of intellectual intuition, and this notion continues to entrance many of Hegel’ commentators. I argue that Kant provided three distinct conceptions of an intuitive intellect, that none of these involve aconceptual intuitionism, and that they differ markedly from Fichte’s and Schelling’s conceptions of intellectual intuition. I further argue that by 1804 Hegel recognized that appealing to an aconceptual model, or to Schelling’s model, or to his own early model of intellectual intuition generates (...) inevitable and insoluble problems of question-begging. By incorporating several important points from Kant’s Transcendental Ideal into his reinterpretation of Kant’s Transcendental Deduction and Refutation of Idealism, Hegel’s mature discursive and conceptual account of ‘absolute knowing’ performs some of the functions Kant assigned to the intuitive intellect, though without invoking any such intuitive intellect. I discuss several of these functions. (shrink)

In this interdisciplinary examination of the discourse of environmentalism, the authors explore the linguistic, philosophical, psychological and cultural-historical aspects of environmental discourse; rather than environmental phenomena themselves. This volume is not advocacy on environmentalism, rather, it is an analysis of the means of persuasion and the techniques of advocacy used by both sides of the environmental debate between `conservationists' and `conservatives'. The book includes an analysis of the concepts of time and space in their linguistic manifestations. Another theme is the (...) interdependencies of the natural world with political and economic institutions. (shrink)

This is the first major textbook to offer a truly comprehensive review of cognitive science in its fullest sense. Ranging across artificial intelligence models and cognitive psychology through to recent discursive and cultural theories Rom Harre offers a breathtakingly original yet accessible integration of the field. At its core this textbook addresses the question "is psychology a science?" with a clear account of scientific method and explanation and their bearing on psychological research. A pivotal figure in psychology and philosophy for (...) many decades Rom Harre has turned his unmatched breadth of reference and insight for students at all levels. Whether describing, language, categorization, memory, the brain or connectionism the book always links our intuitions about beliefs, desires and their social context to the latest accounts of their place in computational and biological models. Fluently written and well structured, this an ideal text for students. The book is divided into four basic modules, with three lectures in each; the reader is guided with helpful learning points, study and essay questions and key readings for each chapter. (shrink)

Analytical study of fundamentals of Nyaya and Mimamsa philosophy.

The Moral Nexus develops and defends a new interpretation of morality—namely, as a set of requirements that connect agents normatively to other persons in a nexus of moral relations. According to this relational interpretation, moral demands are directed to other individuals, who have claims that the agent comply with these demands. Interpersonal morality, so conceived, is the domain of what we owe to each other, insofar as we are each persons with equal moral standing. The book offers an interpretative argument (...) for the relational approach. Specifically, it highlights neglected advantages of this way of understanding the moral domain; explores important theoretical and practical presuppositions of relational moral duties; and considers the normative implications of understanding morality in relational terms. The book features a novel defense of the relational approach to morality, which emphasizes the special significance that moral requirements have, both for agents who are deliberating about what to do and for those who stand to be affected by their actions. The book argues that relational moral requirements can be understood to link us to all individuals whose interests render them vulnerable to our agency, regardless of whether they stand in any prior relationship to us. It also offers fresh accounts of some of the moral phenomena that have seemed to resist treatment in relational terms, showing that the relational interpretation is a viable framework for understanding our specific moral obligations to other people.

Science is as much defined by the local “instrumentarium,” the equipment available to an experimenter at a particular time and place, as by its discoveries and theories. Instruments are devices for detecting and measuring natural phenomena, linked causally to those aspects of nature they are used to record. Some are inorganic, made of glass and metal, while others are organic, the bodies and body parts of living or once living plants and animals. In contrast, pieces of apparatus are quite different (...) in the ways in which they work. They too can be organic or inorganic, but their role is to model things, process, structures, and so on in the natural world. They are used to study natural processes by simulating them in a user-friendly way. Keeping the distinction between instruments and apparatus in mind is crucial to understanding the power of the experimental method. (shrink)

It is commonplace for a single physiological mechanism to seed multiple phenomena, and for multiple mechanisms to contribute to a single phenomenon. We propose that the flash-lag effect should not be considered a phenomenon with a single cause. Instead, its various aspects arise from the convergence of a number of different mechanisms proposed in the literature. We further give an example of how a neuron's generic spatio-temporal response profile can form a physiological basis not only of but also of many (...) of the other proposed flash-lag mechanisms, thus recapitulating a spectrum of flash-lag phenomena. Finally, in agreeing that such basic predictive mechanisms are present throughout the brain, we argue that motor prediction contributes more to biological fitness than visual prediction. (shrink)

Responsibility and the Moral Sentiments offers an account of moral responsibility. It addresses the question: what are the forms of capacity or ability that render us morally accountable for the things we do? A traditional answer has it that the conditions of moral responsibility include freedom of the will, where this in turn involves the availability of robust alternative possibilities. I reject this answer, arguing that the conditions of moral responsibility do not include any condition of alternative possibilities. In the (...) terms that have become familiar, the book thus defends a compatibilist account of moral responsibility. (shrink)

Language based criticisms of the intelligibility of the programme of neuropsychology have made use of the principle that words the meaning of which is established in the context of descriptions of aspects of whole persons cannot be used in that sense to ascribe properties to parts of human bodies. In particular neither human brains nor their parts think, are conscious, imagine, suffer and so on. Recently, Bennett and Hacker have presented the error as a mereological fallacy, because brains are parts (...) of persons. However, while brains are parts of human bodies it is not clear that they are parts of persons. I restyle the argument in terms of fields of family resemblances, in such a way that it makes sense to describe the hippocampus as an organ for remembering, but does not support the claim that neuroscience is core psychology. Such fields are networks of meanings linked by two principles. (1) Taxonomies of relevant body parts are determined by the psychological role they play in everyday human life. (2) Many body parts are also identified by the role they play as tools in human activities including psychological tasks. Arguments are developed to show that objections to the idea that brains and their constituent organs are tools are misplaced. Hybrid psychologies are possible. (shrink)
