ABSTRACTThe emergence of dimensional analysis in the early nineteenth century involved a redefinition of the pre-existing concepts of homogeneity and dimensions, which entailed a shift from a qualitative to a quantitative conception of these notions. Prior to the nineteenth century, these concepts had been used as criteria to assess the soundness of operations and relations between geometrical quantities. Notably, the terms in such relations were required to be homogeneous, which meant that they needed to have the same geometrical dimensions. The (...) latter reflected the nature of the quantities in question, such as volume vs area. As natural philosophy came to encompass non-geometrical quantities, the need arose to generalize the concept of homogeneity. In 1822, Jean Baptiste Fourier consequently redefined it to be the condition an equation must satisfy in order to remain valid under a change of units, and the ‘dimension' correspondingly became the power of a conversion factor. When these innovations eventually found an echo in France and Great Britain, in the second half of the century, tensions arose between the former, qualitative understanding of dimensions as reflecting the nature of physical quantities, and the new, quantitative conception based on unit conversion and measurement. The emergence of dimensional analysis thus provides a case study of how existing rules and concepts can find themselves redefined in the context of wider conceptual changes; in the present case this redefinition involved a generalization, but also a shift in meaning which led to conceptual tensions.

Many philosophers doubt that one can provide any successful explanation of sensory qualities - of how things look, feel, or seem to a perceiving subject. To provide such an explanation, one would need to explain qualitative facts in non-qualitative terms. Attempts to construct such explanations have seemed, in principle, doomed. Austen Clark examines the strategy used in psychophysics, psychometrics, and sensory neurophysiology to explain qualitative facts. He argues that this strategy could succeed: its structure is sound, and it can (...) answer the various philosophical objections lodged against it. On this basis Professor Clark presents an analysis of senosry qualities that offers the possibility of explaining at least some qualia, and he sketches how this scheme might eventually reduce to neurophysiology. If he is correct, we are not doomed to an eternity of mere acquaintance with our qualia. (shrink)

Strange inversions occur when things work in ways that turn received wisdom upside down. Hume offered a strangely inverted story about causation, and Darwin, about apparent design. Dennett suggests that a strange inversion also occurs when we project our own reactive complexes outward, painting our world with elusive properties like cuteness, sweetness, blueness, sexiness, funniness, and more. Such properties strike us as experiential causes, but they are really effects—a kind of shorthand for whole sets of reactive dispositions rooted in the (...) nuts and bolts of human information processing. Understanding the nature and origins of that strange inversion, Dennett believes, is thus key to understanding the nature and origins of human experience itself. This paper examines this claim, paying special attention to recent formulations that link that strange inversion to the emerging vision of the brain as a Bayesian estimator, constantly seeking to predict the unfolding sensory barrage.

In lieu of an abstract, here is a brief excerpt of the content:Report on the Ninth European Network of Buddhist-Christian Studies Conference:"Hope: A Form of Delusion? Buddhist and Christian Perspectives"Elizabeth J. Harris, President of the NetworkCan we hope in a world that is shot through with suffering? Should hope be shunned as a form of attachment? Should we affirm our hope or let go of it? And, if we embrace hope, what should we hope for and what can inspire us? (...) Between sixty and seventy people, from sixteen countries, came together to address questions such as these at the ninth conference of the European Network of Buddhist-Christian Studies, held in glorious weather at Liverpool Hope University in England, between 30 June and 4 July 2011.At the heart of the conference were ten keynote presentations on five crucial aspects of the theme of hope: "Hope and the Critique of Hope," "Hope in Pastoral Situations," "Embodiments of Hope," "Hope in Situations of Hopelessness: Engaged Buddhism and Liberation Theology," and "Eschatologies of Hope." Dr. Sybille Fritsch-Oppermann (Church of Southern Hesse) gave the introductory lecture, which suggested that hope can be seen both as a utopian ideal within and beyond living religions, and a working hypothesis, through which humans can strive toward truth and transcendence.Each theme was addressed from a Buddhist and a Christian perspective, followed by a plenary to enable dialogue between the speakers, and between speakers and participants. Addressing the first theme, "Hope and the Critique of Hope," from a Buddhist perspective, Richard Gombrich (Balliol College, Oxford) robustly argued that hope was not a category relevant to Theravada Buddhism, distinguishing between hope and confidence, and hope and expectation. Werner Jeanrond (Glasgow University), taking the Christian perspective, suggested that a critical theology of hope—an inter-hope dialogue—is necessary, within a critique of other key concepts such as salvation, faith, and love. [End Page 135]Within the session titled "Hope in Pastoral Situations," Dr. Hiroshi Munehiro Niwano (Rissho Kosei-kai, Japan) focused on Rissho Kosei-kai's pastoral work, most movingly its response to the recent earthquake and tsunami in Japan. Notto Thelle (Oslo University), speaking from a Christian viewpoint, sensitively explored pastoral situations caused by life experiences that seem to question and make a mockery of hope, drawing on decades of Buddhist-Christian encounter. Peggy Morgan (Mansfield College, Oxford), addressing the third theme, "Embodiments of Hope," concretized her brief by focusing on a contemporary embodiment of hope capable of emboldening Christians: Rosemary Radford Ruether and her listening dialogue with Buddhism. Mitsuya Dake (Ryukoku University, Japan), on the other hand, chose Amida Buddha as his empowering embodiment of the wisdom, compassion, and non-dualism that lies at the heart of Buddhism, focusing on Shinran's understanding.The theme "Hope in Situations of Hopelessness" was opened to the public in an evening session. Sallie King (James Madison University, USA), using examples such as the Sarvodaya Movement in Sri Lanka and the Dalai Lama's peace work, argued that Buddhism is "loaded" with hope, from an Engaged Buddhist perspective. Buddhist hope, at one level, is an amalgam of acceptance, lawful change, and effort. At another level, it is the conviction that everyone has the potential to change and that truth has power. Sathianathan Clarke (Wesley Theological College, Washington, D.C.) movingly examined Dalit liberation theology, suggesting that hope within this context could be seen as a proxy topos that extends faith into life, an alter-wisdom where love can enrich life, and an energy, a verb, leading to transformative action.Addressing the last theme, "Eschatologies of Hope," Anthony Kelly (Australian Catholic University) recognized a contemporary crisis of hope and, distinguishing between hope as an emotion and hope as a virtue, explored a paradox: that Christian hope is rooted in the resurrection of the crucified Jesus but that this event is described in a varied rhetoric of negations. Justin Ritzinger (Oberlin College, USA), noting that endings are hard to find in Buddhist literature, examined the coming of Maitreya, the future Buddha, as a possible candidate for a Buddhist eschaton. He concluded that the similarities to Christian eschatology are superficial, with the exception of a contemporary reinvention of the Maitreyan tradition in China.In addition to invited keynote speakers, a...

The Ethics of Need: Agency, Dignity, and Obligation argues for the philosophical importance of the notion of need and for an ethical framework through which we can determine which needs have moral significance. In the volume, Sarah Clark Miller synthesizes insights from Kantian and feminist care ethics to establish that our mutual and inevitable interdependence gives rise to a duty to care for the needs of others. Further, she argues that we are obligated not merely to meet others’ needs (...) but to do so in a manner that expresses "dignifying care," a concept that captures how human interactions can grant or deny equal moral standing and inclusion in a moral community. She illuminates these theoretical developments by examining two cases where urgent needs require a caring and dignifying response: the needs of the elderly and the needs of global strangers. Those working in the areas of feminist theory, women’s studies, aging studies, bioethics, and global studies should find this volume of interest. (shrink)

This paper critiques the view that consciousness is likely something extra which accompanies or is produced by neural states, something beyond the functional cognitive processes realized in the brain. Such a view creates the `explanatory gap'between function and nomenology which many suppose cannot be filled by functionalist theories of mind. Given methodological considerations of simplicity, ontological parsimony, and theoretical conservatism, an alternative hypothesis is recommended, that subjective qualitative experience is identical to certain information-bearing, behaviour-controlling functions, not something which emerges from (...) them. This hypothesis explains the isomorphism between the structure of experience and neural organization, while providing a naturalistic account of qualiait's relational properties of informational states, not a sparate ontology of phenomenal essences. On this functionalist view, the hard, empirical problem of consciousness is to discover precisely which neural functions constitute subjective experience. (shrink)

In this paper, I contest increasingly common "realist" interpretations of Hegel's theory of "the concept" (der Begriff), offering instead a "isomorphic" conception of the relation of concepts and the world. The isomorphism recommended, however, is metaphysically deflationary, for I show how Hegel's conception of conceptual form creates a conceptually internal standard for the adequacy of concepts. No "sideways-on" theory of the concept-world relationship is envisioned. This standard of conceptual adequacy is also "graduated" in that it allows for a lack of (...) fit between concept and world. The possibility for a "maximally isomorphic" fit between concept and world obtains through the teleological realization of concepts, which marks especially the "artificial" world of human culture (law, art, religion, etc.). Some of the most seemingly exaggerated claims Hegel makes about the concept, I contend, can be understood when we consider the significance Hegel ascribes to human making, which is provided for in his conceptual theory. But my framework provides an interpretive key for the way Hegel sees concepts imperfectly realized in the natural world as well. (shrink)

Adams and Aizawa, in a series of recent and forthcoming papers ((2001), (In Press), (This Volume)) seek to refute, or perhaps merely to terminally embarrass, the friends of the extended mind. One such paper begins with the following illustration: "Question: Why did the pencil think that 2+2=4? Clark's Answer: Because it was coupled to the mathematician" Adams and Aizawa (this volume) ms p.1 "That" the authors continue "about sums up what is wrong with Clark's extended mind hypothesis". The (...) example of the pencil, they suggest, is just an especially egregious version of a fallacy said to pervade the literature on the extended mind. This fallacy, which they usefully dub the "coupling-constitution fallacy", is attributed , in varying degrees and manners, to Van Gelder and Port (1995), Clark and Chalmers (1998), Haugeland (1998), Dennett (2000), Clark (2001), Gibbs (2001), and Wilson (2004). The fallacy, of course, is to move from the causal coupling of some object or process to some cognitive agent, to the conclusion that the object or process is part of the cognitive agent , or part of the agent's cognitive processing (see e.g. Adams and Aizawa (This volume) ms p.2). Proponents of the extended mind and related theses, Adams and Aizawa repeatedly assert, are prone to this fallacy in part because they either ignore or fail to properly appreciate the importance of " the mark of the cognitive" viz the importance of an account of "what makes something a cognitive agent" (op cit ms p.3). The positive part of Adams and Aizawa's critique then emerges as a combination of the assertion that this "mark of the cognitive" involves the idea that "cognition is constituted by certain sorts of causal process that involve non-derived contents" (e.g. op cit ms p.3) and that these processes look to be characterized by psychological laws that turn out to apply to many internal goings-on but not currently (as a matter of contingent empirical fact) to any processes that take place in non-biological tools and artifacts. In what follows, I shall try to show why these arguments display nothing so much as mutual failures of communication: crossed wires concealing a couple of real, important, but much more subterranean, disagreements. In particular, I try to show why the negative considerations advanced by Adams and Aizawa fail to successfully undermine the argument for the extended mind, and why their more radical positive story, unless supplemented by implausible additional claims, fails to cast doubt on the claim that minds like ours can (without the need for any radically new techniques, technologies or interventions) extend into the world.

By combining experimental interventions with search procedures for graphical causal models we show that under familiar assumptions, with perfect data, N - 1 experiments suffice to determine the causal relations among N > 2 variables when each experiment randomizes at most one variable. We show the same bound holds for adaptive learners, but does not hold for N > 4 when each experiment can simultaneously randomize more than one variable. This bound provides a type of ideal for the measure of (...) success of heuristic approached in active learning methods of casual discovery, which currently use less informative measures. (shrink)

This volume brings together fourteen mostly previously published articles by the prominent Nietzsche scholar Maudemarie Clark. Thus, it will allow readers to see more easily how Clark's views fit together as a whole, exhibit important developments of her ideas, and highlight her distinctive voice in Nietzsche studies.

Connectionism and classicism, it appears, have at least this much in common: both place some notion of internal representation at the heart of a scientific study of mind. In recent years, however, a much more radical view has gained increasing popularily. This view calls into question the commitment to internal representation itself. more strikingly still, this new wave of anti-representationalism is rooted not in 'armchair' theorizing but in practical attempts to model and understand intelligent, adaptive behaviour. In this paper we (...) first present, and then critically assess, a variety of recent anti-representationalist treatments. We suggest that so far, at least, the sceptical rhetoric outpaces both evidence and argument. Some probable causes of this premature scepticism are isolated. nonetheless, the anti-representationalist challenge is shown to be both important and progressive insofar as it forces us to see beyond the bare representational/ non-represenational dichotomy and to recognize instead a rich continuum of degrees and types of represenatationality.

Advanced biological brains are by nature open-ended opportunistic controllers. Such controllers compute, pretty much on a moment-to-moment basis, what problem-solving resources are readily available and recruit them into temporary problem-solving wholes. Neural plasticity, exaggerated in our own species, makes it possible for such resources to become factored deep into both our cognitive and physical problem-solving routines. One way to think about this is to depict the biological brain as a master of what I shall dub ‘ecological control’. Ecological control is (...) the kind of top-level control that does not micro-manage every detail, but rather encourages substantial devolvement of power and responsibility. This kind of control allows much of our skill at walking to reside in the linkages and elastic properties of muscles and tendons. And it allows much of our prowess at thought and reason to depend upon the robust and reliable operation, often in dense brain-involving loops, of a variety of non-biological problem-solving resources spread throughout our social and technological surround. Are the complex distributed systems that result in some sense ‘out of control’, beyond the reach of useful governance? I shall argue that they are not, although understanding them requires us to re-think some key ideas about control and the nature of the self. To make this case, I shall first examine some strategies for efficient, external opportunity exploiting control in simple systems. I shall then argue that many of the same lessons apply to the case of higher-level human problem-solving. (shrink)

Twenty years ago, people thought only cranks or sentimentalists could be seriously concerned about the treatment of non-human animals. However, since then philosophers, scientists and welfarists have raised public awareness of the issue; and they have begun to lay the foundations for an enormous change in human practice. This book is a record of the development of 'animal rights' through the eyes of one highly-respected and well-known thinker. This book brings together for the first time Stephen R.L. Clark's major (...) essays in one volume. Written with characteristic clarity and persuasion, Animals and Their Moral Standing will be essential reading for both philosophers and scientists, as well as the general reader concerned by the debates over animal rights and treatment.

The present study examined the neural substrate of two classes of quantifiers: numerical quantifiers like ” at least three” which require magnitude processing, and logical quantifiers like ” some” which can be understood using a simple form of perceptual logic. We assessed these distinct classes of quantifiers with converging observations from two sources: functional imaging data from healthy adults, and behavioral and structural data from patients with corticobasal degeneration who have acalculia. Our findings are consistent with the claim that numerical (...) quantifier comprehension depends on a lateral parietal-dorsolateral prefrontal network, but logical quantifier comprehension depends instead on a rostral medial prefrontal-posterior cingulate network. These observations emphasize the important contribution of abstract number knowledge to the meaning of numerical quantifiers in semantic memory and the potential role of a logic-based evaluation in the service of non-numerical quantifiers.

How do questions concerning consciousness and phenomenal experience relate to, or interface with, questions concerning plans, knowledge and intentions? At least in the case of visual experience the relation, we shall argue, is tight. Visual perceptual experience, we shall argue, is fixed by an agent’s direct unmediated knowledge concerning her poise (or apparent poise) over a currently enabled action space. An action space, in this specific sense, is to be understood not as a fine-grained matrix of possibilities for bodily movement, (...) but as a matrix of possibilities for pursuing and accomplishing one’s intentional actions, goals and projects. If this is correct, the links between planning, intention and perceptual experience are tight, while (contrary to some recent accounts invoking the notion of ‘sensorimotor expectations’) the links between embodied activity and perceptual experience, though real, are indirect. What matters is not bodily activity itself, but our practical knowledge (which need not be verbalized or in any way explicit) of our own possibilities for action. Such knowledge, selected, shaped and filtered by the grid of plans, goals, and intentions, plays, we argue, a constitutive role in explaining the content and character of visual perceptual experience.
