Gravitational interactions allowed astronomers to conclude that dark matter rings all luminous galaxies in gigantic halos, but this only accounts for a fraction of the total mass of dark matter believed to exist. Where is the rest? We hypothesize that some of it resides in dark galaxies, pure dark matter halos that either never possessed or have totally lost their baryonic matter. This article explores methodological challenges that arise because of the nature of observation in astrophysics and examines how the (...) blend of observation, simulation, and theory we call the Observing the Invisible approach might make detecting such dark objects possible.

Whether we're buying a pair of jeans, ordering a cup of coffee, selecting a long-distance carrier, applying to college, choosing a doctor, or setting up a 401(k), everyday decisions ; both big and small ; have become increasingly complex due to the overwhelming abundance of choice with which we are presented. As Americans, we assume that more choice means better options and greater satisfaction. But beware of excessive choice: choice overload can make you question the decisions you make before you (...) even make them, it can set you up for unrealistically high expectations, and it can make you blame yourself for any and all failures. In the long run, this can lead to decision-making paralysis, anxiety, and perpetual stress. And, in a culture that tells us that there is no excuse for falling short of perfection when your options are limitless, too much choice can lead to clinical depression. In The Paradox of Choice, Barry Schwartz explains at what point choice ; the hallmark of individual freedom and self-determination that we so cherish ; becomes detrimental to our psychological and emotional well-being. In accessible, engaging, and anecdotal prose, Schwartz shows how the dramatic explosion in choice ; from the mundane to the profound challenges of balancing career, family, and individual needs ; has paradoxically become a problem instead of a solution. Schwartz also shows how our obsession with choice encourages us to seek that which makes us feel worse. By synthesizing current research in the social sciences, Schwartz makes the counter intuitive case that eliminating choices can greatly reduce the stress, anxiety, and busyness of our lives. He offers eleven practical steps on how to limit choices to a manageable number, have the discipline to focus on those that are important and ignore the rest, and ultimately derive greater satisfaction from the choices you have to make."--provided by publisher.

Since the 1970s Barry Stroud has been one of the most original contributors to the philosophical study of human knowledge. This volume presents the best of Stroud's essays in this area. Throughout, he seeks to clearly identify the question that philosophical theories of knowledge are meant to answer, and the role scepticism plays in making sense of that question. In these seminal essays, he suggests that people pursuing epistemology need to concern themselves with whether philosophical scepticism is true or (...) false. Stroud's discussion of these fundamental questions is essential reading for anyone whose work touches on the subject of human knowledge. (shrink)

Distinguished scholar Barry Stroud presents a sustained and intricate philosophical argument based upon the question of whether physical objects are 'actually' coloured, or whether they merely appear to be so. He demonstrates how this specific question is inextricably linked to some of the most fundamental issues in metaphysics. He also questions the very nature and constitution of these specific metaphysical issues. This long-awaited model of subtle, elegant, and rigorous philosophical writing ahould have a wide readership among philosophers working in (...) all areas of philosophy. (shrink)

Can there be a theory-free experience? And what would be the object of such an experience. Drawing on ideas set out by Husserl in the “Crisis” and in the second book of his “Ideas”, the paper presents answers to these questions in such a way as to provide a systematic survey of the content and ontology of common sense. In the second part of the paper Husserl’s ideas on the relationship between the common-sense world (what he called the ‘life-world’) and (...) the world of physical theory are subjected to a critical evaluation. The relation of Husserl’s ideas to current work in folk psychology and naive physics and to the direct realism of J. J. Gibson are also treated. (shrink)

The paper uses the tools of mereotopology (the theory of parts, wholes and boundaries) to work out the implications of certain analogies between the 'ecological psychology' of J. J Gibson and the phenomenology of Edmund Husserl. It presents an ontological theory of spatial boundaries and of spatially extended entities. By reference to examples from the geographical sphere it is shown that both boundaries and extended entities fall into two broad categories: those which exist independently of our cognitive acts (for example, (...) the planet Earth, its exterior surface); and those which exist only in virtue of such acts (for example: the equator, the North Sea). The visual field, too, can be conceived as an example of an extended entity that is dependent in the sense at issue. The paper suggests extending this analogy by postulating entities which would stand to true judgments as the visual field stands to acts of visual perception. The judgment field is defined more precisely as that complex extended entity which comprehends all entities which are relevant to the truth of a given (true) judgment. The work of cognitive linguists such as Talmy and Langacker, when properly interpreted, can be shown to yield a detailed account of the structures of the judgment fields corresponding to sentences of different sorts. A new sort of correspondence-theoretic definition of truth for sentences of natural language can then be formulated on this basis. (shrink)

As is widely appreciated and easily demonstrated, the notion that we are essentially experiential (or conscious) beings has a good deal of appeal; what is less obvious, and more controversial, is whether it is possible to devise a viable account of the self along such lines within the confines of a broadly naturalistic metaphysical framework. There are many avenues to explore, but here I confine myself to outlining the case for one particular approach. I suggest that we should think of (...) ourselves (or our essential cores) as being composed of experience-producing systems, and that such systems belong to the same self when they have the capacity to contribute to unified streams of consciousness. The viability of this proposal rests in turn on a particular conception of the structure of consciousness, both at and over time; this conception is defended in the first part of the paper..

Meaning, Understanding, and Practice is a selection of the most notable essays of leading contemporary philosopher Barry Stroud on a set of topics central to analytic philosophy. In this collection, Stroud offers penetrating studies of meaning, understanding, necessity, and the intentionality of thought. Throughout he asks how much can be expected from a philosophical account of one's understanding of the meaning of something, and questions whether such an account can succeed without implying that the person understands many other things (...) as well. Most of the essays work with ideas derived from Wittgenstein, and five of the essays focus specifically on Wittgenstein's philosophy. Stroud's helpful introduction draws out the recurring themes he pursues and explains how his ideas and aims have developed over the years. (shrink)

In his book The Sensory Order, Hayek anticipates many of the central ideas behind what we now call the connectionist paradigm, and develops on this basis a theory of the workings of the human mind that extends the thinking of Hume and Mach. He shows that the idea of neural networks is can be applied not only in psychology and neurology but also in the sphere of economics. For the mind, from the perspective of The Sensory Order, is a dynamic, (...) relational affair that is in many respects analogous to a market process. The mind, as Hayek puts it, is a 'continuous stream of impulses, the significance of each and every contribution of which is determined by the place in the pattern of channels through which they flow' , so that the flow of representative neural impulses can be compared 'to a stock of capital being nourished by inputs and giving a continuous stream of outputs'.

We say "the grass is green" or "lemons are yellow" to state what everyone knows. But are the things we see around us really colored, or do they only look that way because of the effects of light rays on our eyes and brains? Is color somehow "unreal" or "subjective" and dependent on our human perceptions and the conditions under which we see things? Distinguished scholar Barry Stroud investigates these and related questions in The Quest for Reality. In this (...) long-awaited book, he examines what a person would have to do and believe in order to reach the conclusion that everyone's perceptions and beliefs about the color of things are "illusions" and do not accurately represent the way things are in the world as it is independently of us. Arguing that no such conclusion could be consistently reached, Stroud finds that the conditions of a successful unmasking of color cannot all be fulfilled. The discussion extends beyond color to present a serious challenge to many other philosophical attempts to discover the way things really are. A model of subtle, elegant, and rigorous philosophical writing, this study will attract a wide audience from all areas of philosophy. (shrink)

This is a revised version of the introductory essay in C. Eschenbach, C. Habel and B.

This book examines what makes someone an evil person and how evil people are different from merely bad people. Rather than focusing on the "problem of evil" that occupies philosophers of religion, Barry looks instead to moral psychology—the intersection of ethics and psychology. He provides both a philosophical account of what evil people are like and considers the implications of that account for social, legal, and criminal institutions. He also engages in traditional philosophical reasoning strongly informed by psychological research, (...) especially abnormal and social psychology. In response to the popularity of phrases like "the axis of evil" and the ease with which politicians and others describe their opponents as "evil," Barry sets out to make clear just what it is to be an evil person.

The first book to focus on the intersection of Western philosophy and the Asian martial arts, _Striking Beauty_ comparatively studies the historical and philosophical traditions of martial arts practice and their ethical value in the modern world. Expanding Western philosophy's global outlook, the book forces a theoretical reckoning with the concerns of Chinese philosophy and the aesthetic and technical dimensions of martial arts practice. _Striking Beauty_ explains the relationship between Asian martial arts and the Chinese philosophical traditions of Confucianism, Buddhism, (...) and Daoism, in addition to Sunzi's _Art of War_. It connects martial arts practice to the Western concepts of mind-body dualism and materialism, sports aesthetics, and the ethics of violence. The work ameliorates Western philosophy's hostility toward the body, emphasizing the pleasure of watching and engaging in martial arts, along with their beauty and the ethical problem of their violence.

Martial-arts practice is not quite anything else: it is like sport, but is not sport; it constantly refers to and as it were cohabits with violence, but is not violent; it is dance-like but not dance. It shares a common athleticism with sports and dance, yet stands apart from both, especially through its paradoxical commitment to the external value of being an instrument of violence. My discussion seeks to illuminate martial arts practice by systematic contrast to games of sport and (...) works of performance art, especially dance. (shrink)

A brief description of the goal and main lines of argument of The Quest for Reality, in reply to the responses of Paul Boghossian and Alex Byrne.

Knowledge and Civilization advances detailed criticism of philosophy's usual approach to knowledge and describes a redirection, away from textbook problems of epistemology, toward an ecological philosophy of technology and civilization. Rejecting theories that confine knowledge to language or discourse, Allen situates knowledge in the greater field of artifacts, technical performance, and human evolution. His wide ranging considerations draw on ideas from evolutionary biology, archaeology, anthropology, and the history of cities, art, and technology.

The book concludes that it is a mistake to think of Art as something subjective, or as an arbitrary social representation, and of Technology as an instrumental ..

Kripke's Wittgenstein on Rules and Private Language has enlivened recent discussion of Wittgenstein's later philosophy. Yet it is quite possible to disengage his interpretive thesis from its supporting argumentation. Doing so leaves one with an intriguing sceptical argument which Kripke first powerfully advances, then tries to halt. But contrary to the impression his argument may leave, Kripke's solution and the position it concedes to the Sceptic are deeply allied. Here I shall demonstrate their common assumption, and on that basis argue (...) that Kripke's solution begs the Sceptic's question. Furthermore, I believe we can live with the Sceptic. The sceptical argument can be turned into a reasonable contribution to a kind of nominalism in the philosophy of meaning and truth. (shrink)

We propose a typology of representational artifacts for health care and life sciences domains and associate this typology with different kinds of formal ontology and logic, drawing conclusions as to the strengths and limitations for ontology in a description logics framework. The four types of domain representation we consider are: (i) lexico-semantic representation, (ii) representation of types of entities, (iii) representations of background knowledge, and (iv) representation of individuals. We advocate a clear distinction of the four kinds of representation in (...) order to provide a more rational basis for using ontologies and related artifacts to advance integration of data and enhance interoperability of associated reasoning systems. We highlight the fact that only a minor portion of scientifically relevant facts in a domain such as biomedicine can be adequately represented by formal ontologies as long as the latter are conceived as representations of entity types. In particular, the attempt to encode default or probabilistic knowledge using ontologies so conceived is prone to produce unintended, erroneous models. (shrink)

(Proceedings of the Aristotelian Society, 1996: 17-36) I If I am to survive until some later date, what must happen, and what must not happen, over the intervening period? I am talking here about survival in the strict sense. Take an earlier and a later person, if they are one and the same, what is it about them that makes this so? In addressing this question the preferred tool has long been the exploitation of imaginary or science fiction cases. We (...) are asked to reflect on scenarios in which an ordinary person is subjected to some unusual treatment which effectively removes one or more of the elements that usually accompanies personal persistence. If we think the subject survives the treatment, the conclusion is drawn that the elements removed are not necessary to personal identity as we conceive it. The hope is that the repeated use of this method, with a variety of scenarios, will finally produce a convergence of intuitive responses as to what is necessary and sufficient for survival. Unfortunately, this method has failed to produce the goods. The literature is brimming with cunningly constructed scenarios yet consensus as to what personal persistence involves seems as elusive as ever. So it is hardly surprising that the method has come in for some criticism recently. There is a feeling that much time has been wasted on devising fantastic stories about which many people have no firm or reliable intuitions. Hence the demand for a different approach. As for the direction the new approach should take, a general trend can be detected: a focusing on human beings, biological entities of a particular kind, with species-specific identity conditions - a move away from science fiction, towards science. I shall be arguing here that this response is premature. Although it would be a mistake to expect too much from the standard method, it delivers at least one significant result: that of the several strands that make up a human life, we believe that one particular strand is of overriding importance in regard to our continued existence.

Brian Barry examines the idea that the demands of justice in a given society can be ascertained by interpreting the shared understandings of the meanings of the goods that are to be distributed. Focusing on Michael Walzer's claims regarding the meanings of such goods as money, health, and leisure, Barry argues that for meanings to determine the uniquely right distributions, the criteria of distribution need to be built into the meanings. He criticizes the implications of Walzer's theory for (...) thinking about global justice. (shrink)

Scholars have detected hostility to technology in Daoist thought. But is this a problem with any machine or only some applications of some machines by some people? I show that the problem is not with machines per se but with the people who introduce them, or more exactly with their knowledge. It is not knowledge as such that causes the disorder Laozi and Zhuangzi associate with machines; it is confused, disordered knowledge—superficial, inadequate, unsubtle, and artless. In other words the problem (...) is not with machines but with the ethics of engineering and the government of technology. The Daoist argument does not devalue machines or knowledge of them; instead, it sets a new goal, defining an alternative ideal—alternative to techniques held hostage to despotic ideas about efficiency and profit.

Henri Bergson and William James were great admirers of each other, and James seemed to think he got valuable ideas from Bergson. But early critics were right to see in Bergson the antithesis of pragmatism. Unfolding this antithesis is a convenient way to study important concepts and innovations in Bergson's philosophy. I concentrate on his ideas of duration and intuition, and show how they prove the necessity of going beyond pragmatism. The reason is because knowledge itself goes beyond the utilitarian (...) limitations in which pragmatism confines it. Knowledge is more than utility, more than adaptation, more than pragmatism, because our cognitive powers prove capable of more than any naturally selected service to survival. (shrink)

Speaking of dental floss contaminated with bacteria, I may separate the dental floss that is sterile from the dental floss that isn’t sterile. The definite description “the dental floss that isn’t sterile” contracts its reference to just the dental floss near bacteria, although it, the dental floss whole, isn’t sterile. To accommodate the definite descriptions that contract their reference, received definitions for ⌜the Φ⌝ are amended from to read as in : ⌜the Φ⌝ refers to that which any Φ is (...) part of and is the least such. ⌜the Φ⌝ refers to that which any Φ overlaps and is the least such. If definite description is to be based on a purely logical notion of plural and mass predication, it is further amended. Like overt demonstratives—⌜this/these Φ⌝, ⌜that/those Φ⌝—any definite description in natural language is also perspectival, scanning everywhere the description Φ is satisfied:⌜the Φ⌝ refers to the least Φ that overlap Φ anywhere there is Φ.

This article confronts Richard Rorty's idea of cultural politics with Bruno Latour's argument for extending democracy to nonhuman things. Why does Latour make this argument? How many of his assumptions might Rorty share? Quite a few, it turns out. Additionally, ethical integration with nonhumans promises to advance the cosmopolitan politics we require for an effective response to ecological crisis.

Many system architects select their system methodologies without explicit consideration of the philosophical perspectives that impact their decisions. This paper describes how the concepts of ontology and epistemology apply in systems science. Ontology is how we specify terms of reference for existence, allowing us to understand the theory of existence via an ‘existence framework’. Epistemology, the theory of knowledge, allows us to explore new models and theories of knowledge acquisition so the best system-based methodologies can be deployed to solve complex (...) system problems. After introducing these concepts, the paper presents system science issues and assesses the impact of ontological, axiological and epistemological perspectives on system methodology selection, research, system design and deployment. An ontological viewpoint such as realism, as an objective view is contrasted versus nationalism, a personal perceptional view. An epistemological viewpoint is explored comparing knowledge as a product of sensory perception or rational reflection. The paper’s significant contribution is that it helps system architects understand that their philosophical views of systems science impact their system methodology choices. (shrink)

Indigenous cultures of North America confronted a problem of knowledge different from that of canonical European philosophy. The European problem is to identify and overcome obstacles to the perfection of knowledge as science, while the Indigenous problem is to conserve a legacy of practice fused with a territory. Complicating the difference is that one of these traditions violently colonized the other, and with colonization the Indigenous problem changes. The old problem of inter-generational stability cannot be separated from the post-colonial problem (...) of sovereignty in the land where the knowledge makes sense. I differentiate the question of the value of knowledge (Part One), and its content (Part Two). The qualities these epistemologies favor define what I call ceremonial knowledge, that is, knowledge that sustains a ceremonial community. The question of content considers the interdisciplinary research of Indigenous and Traditional Ecological Knowledge, as well as the issue of epistemic decolonization. (shrink)

The forms and specific situations of the government of men by one another in a given society are multiple; they are superimposed, they cross, impose their own limits, sometimes cancel one another out, sometimes reinforce one another. According to a commonplace in the critical discussion of Foucault's later work, he is supposed to have decided to take up Nietzsche's interpretation of power as Wille zur Macht, ‘will to power.’ For instance, Habermas believes he has criticized Foucault when he says, ‘Nietzsche’s (...) authority, from which this [Foucault’s] utterly unsociological concept of power is borrowed, is not enough to justify its systematic usage.’ Charles Taylor finds in Nietzsche ‘a doctrine which Foucault seems to have made his own,’ viz., that ‘there is no order of human life, or way we are, or human nature, that one can appeal to in order to judge or evaluate between ways of life.

The now-global phenomenon of Asian martial arts traces back to something that began in China. The idea the Chinese communicated was the dual cultivation of the spiritual and the martial, each perfected in the other, with the proof of perfection being an effortless mastery of violence. I look at one phase of the interaction between Asian martial arts and Chinese thought, with a reading of the Zhuangzi 莊子 and the Daodejing 道德經 from a martial arts perspective. I do not claim (...) that the authors knew about martial arts. It was not Daoist masters who took up martial arts, but martial arts masters who, at a specific time, turned to Daoism to explain the significance of their art. Today, though, Daoist concepts are ubiquitous in martial arts literature, and a reading of these classics from a martial arts perspective shows how they lend themselves to philosophical thinking about this practice.

Since Fodor 1970, negation has worn a Homogeneity Condition to the effect that homogeneous predicates, ) denote homogeneously—all or nothing —to characterize the meaning of – when uttered out-of-the blue, in contrast to –:The mirrors are smooth.

An impoverished logical form – has been the occasion to embellish all else—Boolean algebra, lexical presuppositions, Strongest Meaning Hypothesis, trivalence, supervaluation, double strengthening, etc., enriching the semantics and pragmatics with what remains a special theory of negation, which may be dismissed when the logical syntax and semantics of negation reflects that negated sentences are also tensed sentences.

It seems plausible to extend to the field of Disability Studies a certain nominalist point of view which is evident in Foucault’s work. What I have in mind is an “implantation of impairments” thesis, modelled after what Foucault calls the “implantation of perversions.” After sketching some features of this Foucauldian argument, I discuss the ideas of knowledge and power that it presupposes, then outline a critical perspective on Foucault’s nominalism.

The claim that chimpanzees make and use tools stands on two feet. One is a simplistic conception of tool; the other is a range of field observations, whose interpretation is not always as ingenuous and objective as their advocates suggest. An important difference little attended to by friends of the chimpanzee’s tool concerns how little their way of life seems to hang on their so-called tools. For us nearly everything does. Without tools, chimpanzees would find other things to eat. But (...) without our tools we are not a naked ape thrown back on its animal nature. We are an nonviable species rapidly heading for extinction. Tools belong to the very ecology of our evolved form of life. The myth of the chimpanzee’s tool has already proved damaging in the history and philosophy of technology. It obscures the unique contribution of technical culture to human ecology, which has no counterpart among chimpanzees. The myth has also inspired the bizarre idea that there is something arbitrary about technical culture — that in a sense we could do without it. That is certainly a mistake, and more serious than a specialist’s error, because any decision about the chimpanzee’s tool is replete with implications for understanding our humanness. (shrink)

I take a skeptical view of the experimentalism Dorf and Sable advocate. I discuss three kinds of doubts: Doubt about the idea of “best practices”; doubt about their understanding of scientific experimentation; and doubt about the value of the Constitutional reform they envision. Their program reduces democracy to competitive rituals and managerial predation. The imperative of comparison threatens practice with destruction. “Benchmarking” is a machine to destroy divergence. To compel such comparison with the force of law would be a catastrophe (...) for the ecology of human practices, an enforced monoculturalism that would make democracy infinitely easier to manage at the price of making it infinitely less democratic.

Kant empahtically denied that living forms unfold according to a mechanical law. Yet if living nature were not law-like, natural science would be futile. The justification for a concept of purposiveness is to ensure “the lawfulness of the contingent” against the last exception. It was not until we learned to think about contingency without effacing it that natural history crossed the threshold of a science, Darwin leading the way. While his theory of evolution proposes mechanical explanations for a wide range (...) of natural historical phenomena, the explanations do not overcome but actually presuppose life’s ultimate contingency.

Similarities between Daoism and Chan (Zen) are often merely verbal, a skillful appropriation by Chan authors of a vocabulary that seems Daoist only to a point, and then departs in a predictable way. What makes the departure predictable is the completely different understanding of emptiness in Chan and Daoism, supporting a no less different understanding of the value of knowledge. Daoism remains optimistic about knowledge in a way Chan is not. Buddhist wisdom exhausts life, extinguishes it, does not nourish it, (...) and therefore cannot satisfy the Daoist conviction concerning the value of knowledge. (shrink)

What is social justice? In _Theories of Justice_ Brian Barry provides a systematic and detailed analysis of two kinds of answers.

Though the first book of a trilogy, _Theories of Justice_ stands alone and constitutes a major contribution to the debate about social justice that began in (...) 1971 with Rawls's _A Theory of Justice_.

It proposes model legislation to prevent abuse and neglect of the medically vulnerable and dependent, and in a piercing and insightful manner, Fr. Barry critically evaluates many contemporary views on these topics, arguing forcefully for a reappraisal of many popular views on these topics.
