Clinical trials of xenotransplantation (XTx) may begin early in the next decade, with kidneys from genetically modified pigs transplanted into adult humans. If successful, transplanting pig hearts into children with advanced heart failure may be the next step. Typically, clinical trials have a specified end date, and participants are aware of the amount of time they will be in the study. This is not so with XTx. The current ethical consensus is that XTx recipients must consent to lifelong monitoring. While (...) this presents challenges to the right to withdraw in the adult population, additional and unanswered questions also linger in the paediatric population. In paediatric XTx, parents or guardians consent not only to the initial treatment of the child but also to lifelong monitoring, thus making a decision whose consequences will remain present as the child develops the capacity for assent, and finally the capacity for informed consent or refusal. This article presents and evaluates unanswered paediatric ethical questions in regard to the right to withdraw from XTx follow-up in the paediatric population. (shrink)

Peter Abelard (1079–1142 ce) was the most wide‐ranging philosopher of the twelfth century. He quickly established himself as a leading teacher of logic in and near Paris shortly after 1100. After his affair with Heloise, and his subsequent castration, Abelard became a monk, but he returned to teaching in the Paris schools until 1140, when his work was condemned by a Church Council at Sens. His logical writings were based around discussion of the “Old Logic”: Porphyry's Isagoge, aristotle'S (...) Categories and On Interpretation and boethius'S textbook on topical inference. They comprise a freestanding Dialectica (“Logic”; probably c.1116), a set of commentaries (known as the Logica [Ingredientibus], c. 1119) and a later (c. 1125) commentary on the Isagoge (Logica Nostrorum Petititoni Sociorum or Glossulae). In a work Abelard called his Theologia, issued in three main versions (between 1120 and c.1134), he attempted a logical analysis of trinitarian relations and explored the philosophical problems surrounding God's claims to omnipotence and omniscience. The Collationes (“Debates,” also known as “Dialogue between a Christian, a Philosopher and a Jew”; probably c.1130) present a rational investigation into the nature of the highest good, in which the Christian and the Philosopher (who seems to be modeled on a philosopher of pagan antiquity) are remarkably in agreement. The unfinished Scito teipsum (“Know thyself,” also known as the “Ethics”; c.1138) analyses moral action. (shrink)

According to current philosophical lore, Kant rejected the notion that philosophy can progress by psychological means and endeavored to restrict it accordingly. This book reverses the frame from Kant the anti-psychological critic of psychological philosophy to Kant the preeminent psychological critic of non-psychological philosophy.

The standard treatment of conditional probability leaves conditional probability undefined when the conditioning proposition has zero probability. Nonetheless, some find the option of extending the scope of conditional probability to include zero-probability conditions attractive or even compelling. This article reviews some of the pitfalls associated with this move, and concludes that, for the most part, probabilities conditional on zero-probability propositions are more trouble than they are worth.

This book argues that Kant's transcendental idealism has been misinterpreted: it denies not simply the super-sensory reality of space, time, and appearances, but their reality outside imagination as well. After adducing extensive and explicit textual evidence in its favor, Waxman shows this interpretation to be essential to the Transcendental Deduction, the affirmation of things in themselves, and the attempt to surmount Hume's scepticism. He further argues that Kant's much-neglected claim that, besides himself, "no psychologist has so much as even thought (...) that the imagination might be a necessary constituent of perception," should be construed so that even our consciousness of sensation itself (visual, tactile, etc.) is impossible without imagination. A compelling and original contribution to Kantian scholarship, Kant's Model of the Mind will also bear close examination by students and scholars of Hume, the philosophy of mind, and the philosophy of science.

This paper outlines an original interactivist-constructivist approach to modelling intelligence and learning as a dynamical embodied form of adaptiveness and explores some applications of I-C to understanding the way cognitive learning is realized in the brain. Two key ideas for conceptualizing intelligence within this framework are developed. These are: intelligence is centrally concerned with the capacity for coherent, context-sensitive, self-directed management of interaction; and the primary model for cognitive learning is anticipative skill construction. Self-directedness is a capacity for integrative process (...) modulation which allows a system to "steer" itself through its world by anticipatively matching its own viability requirements to interaction with its environment. Because the adaptive interaction processes required of intelligent systems are too complex for effective action to be prespecified learning is an important component of intelligence. A model of self-directed anticipative learning is formulated based on interactive skill construction, and argued to constitute a central constructivist process involved in cognitive development. SDAL illuminates the capacity of intelligent learners to start with the vague, poorly defined problems typically posed in realistic learning situations and progressively refine them, transforming them into problems with sufficient structure to guide the construction of a solution. Finally, some of the implications of I-C for modelling of the neuronal basis of intelligence and learning are explored; in particular, Quartz and Sejnowski's recent neural constructivism paradigm, enriched by Montague and Sejnowski's dopaminergic model of anticipative-predictive neural learning, is assessed as a promising, but incomplete, contribution to this approach. The paper concludes with a fourfold reflection on the divergence in cognitive modelling philosophy between the I-C and the traditional computational information processing approaches. (shrink)

What does it mean to say that a scientific theory is unified? Prominent attempts by John Watkins, Philip Kitcher, and Margaret Morrison to answer this question face serious difficulties, and many analysts of science remain pessimistic about the possibility of ever rendering precise or explaining what theoretical unity consists in. This paper gives grounds for optimism, offering a novel account of the concept of unification. This account is tested against a detailed study of the standard model in contemporary high-energy physics, (...) a theory for which a high degree of unity has repeatedly been claimed. (shrink)

This paper proposes a subjectivist approach to color within the framework of an externalist form of representationalism about phenomenal consciousness. Motivations are presented for accepting both representationalism and color subjectivism, and an argument is offered against the case made by Michael Tye on behalf of the claim that colors are objective, physical properties of objects. In the face of the considerable difficulties associated with finding a workable realist theory of color, the alternative account of color experience set out, projectivist representationalism, (...) claims that the color properties we encounter in experience exist only in the representational contents of our experiences. Color experiences are caused by the physical structure of objects, but objects are never actually colored and color experiences systematically misrepresent objects as colored. However, despite being an error theory of color, projectivist representationalism does not do violence to our everyday use and understanding of color concepts and terms, nor does it undermine the role of color experience in aiding the perceiving subject in navigating through the world.

The goal of this paper is to show how scientific explanation functions in the context of idealized models. It argues that the aspect of explanation most urgently requiring investigation is the nature of the connection between global theories and explanatory local models. This aspect is neglected in traditional accounts of explanation. The paper examines causal, minimal model, and structural accounts of model-based explanation. It argues that they too fail to offer an account of the connection with global theory that can (...) justify the explanatory power of an idealized local model, and consequently these accounts are unable effectively to distinguish explanatory from non-explanatory models. On the account proposed here, scientific explanation requires theoretical integration between the local model described in the explanation and a global theory with independent explanatory power.

There are good reasons for pursuing a theory of knowledge by way of understanding the connection between knowledge and luck. Not surprisingly, then, there has been a burgeoning of interest in “luck theories” of knowledge as well as in theories of luck in general. Unfortunately, “luck” proves to be as recalcitrant an analysandum as “knows.” While it is well worth pursuing a general theory of luck despite these difficulties, our theory of knowledge might be made more manageable if we could (...) find a more restricted notion that captured the core phenomena of luck that are relevant to whether or not someone knows. This essay makes the attempt to delineate such a notion, called “mere coincidence.”. (shrink)

The nineteenth-century metaphor of a block universe in which science is regarded as a structure consisting of basic building blocks resting on firm foundations is contrasted with the contemporary metaphor of science as a network of relations. The network metaphor challenges the view that one science is more foundational than others and raises questions about whether an all-pervasive unity is desirable or even possible. The unity-disunity issue in psychology and other sciences is discussed with respect to the network and building (...) block metaphors and with respect to three arenas: organizations, methodology, and subject content areas. It is argued that in these three arenas, psychology is no more disunified than biology. There is no basis for the development of a disciplinary inferiority complex based on the belief that the other sciences are unified while psychology remains in the intellectual backwaters of plurality.

The rapidly expanding aging population presents an urgent global challenge cutting through just about every dimension of worldly life, including the social, political, cultural, and economic. Developing innovations in health and assistive technology (AT) are poised to support effective and sustainable health care in the face of this challenge, yet there is scant (but growing) discussion of the ethical issues surrounding AT for older persons with dementia. Demands for ethical frameworks that can respond to frontline dilemmas regarding AT development and (...) provision, and how the needs of aging persons themselves are defined throughout this development process, are increasing. This article suggests that fulfilling the promises of AT to provide effective and ethically informed solutions may demand shifting away from standard bioethical analyses that centralize the principle of respect for autonomy. An autonomy-centric paradigm is dubiously equipped to theorize the foundational ethical issues in dementia care and to effectively guide AT development and implementation. An agency-centered approach to dementia care, which could engage more adaptively with the perspectives and choices of older persons themselves while offering strong support to AT research and stakeholders, may offer an attractive alternative.

Many philosophers now regard causal approaches to explanation as highly promising, even in physics. This is due in large part to James Woodward's influential argument that a wide variety of scientific explanations are causal, based on his interventionist approach to causation. This article argues that some derivations describing causal relations and satisfying Woodward's criteria for causal explanation fail to be explanatory. Further, causal relations are unnecessary for a range of explanations, widespread in physics, involving highly idealized models. These constitute significant (...) limitations on the scope of causal explanation. We have good reason to doubt that causal explanation is as widespread or important in physics as Woodward and other proponents maintain. (shrink)

Kant took up the issue of origin in the Metaphysical Deduction of the Categories. He sought to demonstrate that the concepts of metaphysics, considered in themselves, are mere logical functions, that is, ways of synthesizing concepts to form judgments Accordingly, the metaphysical concept of substance/accident contains nothing more than the logical form of subject/predicate, whereby any arbitrary pair of concepts may be united in a judgment; cause and effect merely the hypothetical form of judgment, whereby any arbitrary pair of judgments (...) may be united as condition and conditioned; totality the form of subordination of one concept to another whereby any species of the one has the other as its genus; and so forth. Logical functions are what remain after we abstract from all content of the concepts in a judgment; they are merely the various ways in which any concept, or judgment, may be combined with any other, and so are utterly devoid of objective sense or signification. More importantly, they comprise the totality of that which may be attributed to the understanding taken by itself, in isolation from the other faculties of the mind: sensibility, desire, and feeling. The understanding, for Kant, is the capacity to judge ; it is not, when considered without relation to other faculties, a faculty of concepts, rules, principles, or even categories. Indeed, if categories may be said to express any content at all, it is simply and solely the relation of the understanding to another faculty. In the case of sensibility--a faculty comprising the manifold of the senses and its synthesis in imagination--categories are obtained when this synthesis is represented universally and a priori, and so represent the "pure synthetic unity of the manifold in general." Similarly, the categories tabulated in the Critique of Practical Reason express the relation of the capacity to judge to the capacity of desire. Thus, aside from "their possibility as a priori cognitions of objects of an intuition in general," the categories of the first Critique are nothing over and above sheer logical forms, through which no objective necessary connection whatsoever can be thought; indeed, so entirely void of all content and objective import are they that even Hume almost certainly would have countenanced them.

This paper explores the role of physically impossible idealizations in model-based explanation. We do this by examining the explanation of gravitational waves from distant stellar objects using models that contain point-particle idealizations. Like infinite idealizations in thermodynamics, biology and economics, the point-particle idealization in general relativity is physically impossible. What makes this case interesting is that there are two very different kinds of models used for predicting the same gravitational wave phenomena, post-Newtonian models and effective field theory models. The paper (...) contends that post-Newtonian models are explanatory while effective field theory models are not, because only in the former can we eliminate the physically impossible point-particle idealization. This suggests that, in some areas of science at least, models invoking ineliminable infinite idealizations cannot have explanatory power. (shrink)

The Reeh-Schlieder theorem asserts the vacuum and certain other states to be spacelike superentangled relative to local quantum fields. This motivates an inquiry into the physical status of various concepts of localization. It is argued that a covariant generalization of Newton-Wigner localization is a physically illuminating concept. When analyzed in terms of nonlocally covariant quantum fields, creating and annihilating quanta in Newton-Wigner localized states, the vacuum is seen to not possess the spacelike superentanglement that the Reeh-Schlieder theorem displays relative to (...) local fields, and to be locally empty as well as globally empty. Newton-Wigner localization is then shown to be physically interpretable in terms of a covariant generalization of the center of energy, the two localizations being identical if the system has no internal angular momentum. Finally, some of the counterintuitive features of Newton-Wigner localization are shown to have close analogues in classical special relativity. (shrink)

The continuous pursuit and support of medical research on both a societal and individual level is frequently presupposed as laudable, or even obligatory. However, some critics have challenged the assumption that medical research ought to be conducted. These critics reject claims that there is a moral obligation to pursue research, and that medical research may always be justifiable given adequate safeguards and regulations. We align ourselves with critics of the research imperative to the extent that we believe that medical research (...) may only be an imperfect obligation, grounded in the principle of beneficence. Our central purpose in this article, however, is not to advance an original argument concerning the .. (shrink)

In this paper, I shall argue that the most moderate and balanced way to view Kant's transcendental philosophy is as a species of psychological investigation analogous to Hume's, but refounded on a doctrine of pure sensibility, such as Hume never allowed himself . This might seem to fly in the face of what many interpreters of Kant deem conventional wisdom: that the burden of proof is on one who claims that psychology is essential to transcendental philosophy. On this view, there (...) is to be found in Kant ‘a more austere strictly transcendental philosophy’, which needs to be carefully distinguished from the psychological doctrines in which it is enmeshed; and they would insist on being convinced of the contrary before abandoning a position that, in their eyes, is the most moderate and balanced an interpreter of Kant can adopt. My purpose in this two-part essay is to urge them to think again. For while there can be no question of Kant's opposition to empiricism, it is equally certain that his praise for Hume was never freer or more unreserved than in respect of the latter's psycho-genetic approach to cognition. So, rather than supposing that Kant ipso facto rejected solutions to philosophical problems grounded on psychology when he rejected Hume's empiricism, it seems to me that the more moderate and balanced interpretive approach is to begin by supposing that Kant's transcendental philosophy is a species of philosophical psychology in the same mould as Hume's, differing from it only by virtue of involving a priori syntheses of a manifold of a priori intuition.

This paper examines the status of unattended visual stimuli in the light of recent work on the role of attention in visual perception. Although the question of whether attention is required for visual experience seems very interesting, this paper argues that there currently is no good reason to take a stand on the issue. Moreover, it is argued that much of the allure of that question stems from a continued attachment to the defective ‘inner picture view’ of experience and a (...) mistaken notion that the ultimate goal of vision is to produce visual experience. The paper considers a promising general account of the content and structure of vision and presents reasons for not taking that account to be committed to any substantive claims about the experiential status of unattended visual stimuli. Also addressed are the active nature of vision and the role of vision in enabling our ecological success. These considerations highlight that visual experience is not the whole of vision and that a much more important question about unattended visual stimuli than whether they are consciously experienced is what contribution they make to how we interact with the world.

This book presents an interpretation of Kant's Critique of Pure Reason as a priori psychologism. It groups Kant's philosophy together with those of the British empiricists--Locke, Berkeley, and Hume--in a single line of psychologistic succession and offers a clear explanation of how Kant's psychologism differs from psychology and idealism. The book reconciles Kant's philosophy with subsequent developments in science and mathematics, including post-Fregean mathematical logic, non-Euclidean geometry, and both relativity and quantum theory. Finally, the author reveals the ways in which (...) Kant's philosophy dovetails with contemporary scientific theorizing about the natural phenomenon of consciousness and its place in nature. This book will be of interest to Kant scholars and historians of philosophy working on the British empiricists. (shrink)

Commentators divide on whether the basic elements of Hume’s philosophy—perceptions, their division into impressions and ideas, and their associative relation—should be construed as objects and relations between objects or as representations of objects and their relations.

We present an approach to combining three areas of research which we claim are all based on information theory: knowledge representation in Artificial Intelligence and Cognitive Science using prototypes, plans, or schemata; formal semantics in natural language, especially the semantics of the `if-then' conditional construct; and the logic of subjunctive conditionals first developed using a possible worlds semantics by Stalnaker and Lewis. The basic premise of the paper is that both schema-based inference and the semantics of conditionals are based on (...) Dretske's notion of information flow and Barwise and Perry's notion of a constraint in situation semantics. That is, the connection between antecedent and consequent of a conditional `if were the case then would be the case' is an informational relation holding with respect to a pragmatically determined utterance situation. The bridge between AI and conditional logic is that a prototype or planning schema represents a situation type, and the background assumptions underlying the application of a schema in a situation correspond to channel conditions on the flow of information. Adapting the work of Stalnaker and Lewis, the semantics of conditionals is modeled by a refinement ordering on situations: a conditional `if then ' holds with respect to a situation if all the minimal refinements of the situation that support also support . We present new logics of situations, information flow, and subjunctive conditionals based on three-valued partial logic that formalizes our approach, and conclude with a discussion of the resulting theory of conditionals, including the "paradoxes" of conditional implication, the difference between truth conditions and assertability conditions for subjunctive conditionals, and the relationship between subjunctive and indicative conditionals.

This discussion provides a brief commentary on each of the papers presented in the symposium on the conceptual foundations of field theories in physics. In Section 2 I suggest an alternative to Paul Teller's (1999) reading of the gauge argument that may help to solve, or dissolve, its puzzling aspects. In Section 3 I contend that Sunny Auyang's (1999) arguments against substantivalism and for "objectivism" in the context of gauge field theories face serious worries. Finally, in Section 4 I claim (...) that Gordon Fleming's (1999) proposal for hyperplane-dependent Newton-Wigner fields differs importantly from his previous arguments about hyperplane-dependent properties in quantum mechanics.

In lieu of an abstract, here is a brief excerpt of the content:Our Best RhetorologistWayne C. BoothAristotle’s Rhetoric: An Art of Character, by Eugene Garver; 328 pp. Chicago: University of Chicago Press, 1994, $53.95.Eugene Garver’s new book is not only an original and challenging account of Aristotle’s Rhetoric. It is one of the fullest and most responsible encounters ever with philosophical, political, and ethical issues raised by the theory and practice of rhetoric. I’ll go even further. Because Garver grapples so (...) well with how Aristotle’s problems differ from ours, and how his solutions do not quite fit what we most need, I hereby confer upon him, without irony, the title of supreme “rhetorologist” (a term he needs but does not use).A rhetorologist is not just “rhetorician” or “rhetorical theorist” or “philosopher of rhetoric.” Garver’s work dramatizes our need for a term for the “comparativist of rhetorics,” the thinker who probes how disparate rhetorical practices and theories compete and are finally, inescapably related. In earlier times when all philosophers were trained to think about rhetoric the term “genuine philosopher” might have served the trick. But it won’t work today.Garver has spent decades on this masterwork of rhetorology, and he thus joins those rare masters-of-interrelated-rhetorics—Kenneth Burke, Richard McKeon, who else?—those who do justice both to the importance and the complexities of a subject that Aristotle has led us into but himself could never have dreamed of, since he had available no fully developed alternative “rhetorics” to do a “-logy” on. [End Page 116]The book is too ambitious and complex to allow full justice here. It is a book not just to read but to study; it is a book to teach from. All attentive readers will find themselves drawn into issues previously dodged, or engaged in quarrels about theses they’ve never met before. Those like me whose interests overlap strongly with Garver’s will of course dispute about some points. What will prove important, as the book gets discussed, will be our recognition of just why the project itself has led Garver, and leads us, into some inescapable juggling with several different and potentially contradictory theses, each of them so important that it must at moments have invited Garver to consider it as primary. Indeed, when an original thinker bites off more than anyone can chew, let alone fully digest, we should not be surprised if we have a hard time deciding just what the main point is. Several times in my first reading I thought, “Garver has mistitled this book: it should be called...”—and then I’d try out a title that fit the argument at that point but would not fit precisely what came next.The result is that different sympathetic readers will find different books here, with at least the following ambiguously related purposes—all of them to my mind either firmly achieved or at least pursued so effectively that refutation will prove difficult. Some of them are the overt theses of particular chapters, but all are found echoed or implied in every chapter. And all are finally and impressively interrelated.IFirst, Garver works, as he must, to show the faults of past readings of the Rhetoric. The chief of these has been the reduction to a handbook for rhetors; it is not a technical handbook, though it can be used as that, but an effort to “construct a civic relation between argument and ethos, so between techn̄e and phron̄esis [prudence]” (p. 77). “Aristotle’s political project is to maximize the active—energeia—side of rhetoric and so civilize the activity of influencing beliefs and judgments and convert into a minor irritant the role played by disreputable tactics such as playing on irrelevant emotions in the hearers” (p. 40). “I have... assumed that instead of doing that job [the ‘handbook’ job] badly, Aristotle is in fact trying to accomplish something else. I see him exhibiting the internal values and standards of rhetorical argument to legislators and citizens” (p. 235), [and thus making possible] “a new conception of the ethical, and of the relation of logos and ethos” (p. 16). “Aristotle’s Rhetoric is about a civic art...
