Closure is the epistemological thesis that if S knows that P and knows that P implies Q, then if S infers that Q, S knows that Q. Fred Dretske acknowledges that closure is plausible but contends that it should be rejected because it conflicts with the plausible thesis: Conclusive reasons (CR): S knows that P only if S believes P on the basis of conclusive reasons, i.e., reasons S wouldn‘t have if it weren‘t the case that P. Dretske develops an (...) analysis of knowing that centers on CR, and argues that the requirement undermines skepticism by implying the falsity of closure. We develop a Dretske-style analysis of knowing that incorporates CR, and we argue that this analysis not only accords with closure, but also implies it. In addition, we argue that the analysis accounts for the prima facie plausibility of closure-invoking skeptical arguments, and nonetheless implies that they are fallacious. If our arguments turn out to be sound, the acceptability of Dretske‘s analysis of knowing will be significantly enhanced by the fact that, despite implying closure, it undermines closure-based skepticism.

The notion of Simulative Reasoning in the study of propositional attitudes within Artificial Intelligence (AI) is strongly related to the Simulation Theory of mental ascription in Philosophy. Roughly speaking, when an AI system engages in Simulative Reasoning about a target agent, it reasons with that agent’s beliefs as temporary hypotheses of its own, thereby coming to conclusions about what the agent might conclude or might have concluded. The contrast is with non-simulative meta-reasoning, where the AI system reasons within a detailed (...) theory about the agent’s (conjectured) reasoning acts. The motive within AI for preferring Simulative Reasoning is that it is more convenient and efficient, because of a simplification of the representations and reasoning processes. The chapter discusses this advantage in detail. It also sketches the use of Simulative Reasoning in an AI natural language processing system, ATT-Meta, that is currently being implemented. This system is directed at the understanding of propositional attitude reports. In ATT-Meta, Simulative Reasoning is yoked to a somewhat independent set of ideas about how attitude reports should be treated. Central here are the claims that (a) speakers often employ commonsense (and largely metaphorical) models of mind in describing agents’ attitudes, (b) the listener accordingly needs often to reason within the terms of such models, rather than on the basis of any objectively justifiable characterization of the mind, and (c) the commonsense models filter the suggestions that Simulative Reasoning comes up with concerning target agents’ reasoning conclusions. There is a yet tighter connection between the commonsense models and the Simulative Reasoning. It turns out that Simulative Reasoning can be rationally reconstructed in terms of a more general type of reasoning about the possibly-counterfactual “world” that the target agent believes in, together with an assumption that that agent has a faithful representation of the world. In the ATT-Meta approach, the reasoner adopts that assumption when it views the target agent through a particular commonsense model (called IDEAS-AS-MODELS). (shrink)

The science of the mind, and of consciousness in particular, needs carefully to consider people's common-sense views of the mind, not just what the mind really is. Such views are themselves an aspect of the nature of (conscious) mind, and therefore part of the object of study for a science of mind. Also, since the common-sense views allow broadly successful social interaction, it is reasonable to look to the common-sense views for some rough guidance as to the real nature of (...) the mind. On the other hand, to the extent that common-sense views are inaccurate, and perhaps even in gross conflict with the true nature of the mind, one interesting scientific question is: why do we hold such views, given our access to our own minds? Why should introspection be limited in a way that allows inaccurate views to hold sway? Now, common-sense views of the mind are revealed in natural language discourse that describes mental states, and such descriptions are largely metaphorical. The metaphors are used within thinking about the mind as well as in language. Therefore the study of metaphor is central to the study of mind. The present article is a preliminary study of the importance of metaphor in the scientific study of consciousness. It concentrates on analysing the nature of a range of important metaphors of mind, briefly discussing the extent to which they can be used to describe or qualify states of consciousness, and pointing to important questions about the nature of consciousness that the study of the metaphors raises. The article further conjectures that the reason people use metaphors in describing themselves is often not (just) that they have intellectually worked out some structural analogy --- e.g., between interactions of physical objects in physical space and interactions of ideas in the mind --- but rather that they {\it feel} their own minds to be as described by the metaphor --- e.g., they feel that the ideas in their minds are interacting physical entities. This matter of how a mind feels to itself is an aspect of the central issue of consciousness, namely its phenomenal quality. -/- (NB: The archived file is a preprint.

The double membrane of the nuclear envelope is a formidable barrier separating the nucleus and cytoplasm of eukaryotic cells. However, movement of specific macromolecules across the nuclear envelope is critical for embryonic development, cell growth and differentiation. Transfer of molecules between the nucleus and cytoplasm occurs through the aqueous channel formed by the nuclear pore complex (NPC)Abbreviations: NPC, nuclear pore complex; GlcNac, N‐acetylglucosamine; WGA, wheat germ agglutinin. Although small molecules may simply diffuse across the NPC, transport of large proteins and (...) RNA requires specific transport signals and is energy dependent. A family of pore glycoproteins modified by O‐linked N‐acetylglucosamine moieties are essential for transport through the NPC. Recent evidence suggests that the regulation of nuclear transport may also involve the inteaction of RNA and nuclear proteins with specific binding proteins that recognize these transport signals. Are these nuclear pore glycoproteins and signal binding proteins the ‘gatekeepers’ that control access to the genetic material? Recent evidence obtained from a combination of biochemical and genetic approaches suggests – perhaps. (shrink)

Jackendoff comes to some appealing overall conclusions, but several of his assumptions and arguments are questionable. The present commentary points out the following problems: oversimplifications in the translation-based argument for the independence of language and thought; a lack of consideration of the possibility of unconscious use of internalized natural languages; insufficient consideration of possible characteristics of languages of thought ; neglect of the possibility of thinking in example-oriented and metaphorical ways; unfair bias in contrasting visual to linguistic imagery; neglect of (...) other types of imagery; and neglect of the possibility of unconscious attentional processes.

The seminal ideas of the most influential modern art educator are presented here as he developed them, in edited transcripts of Viktor Lowenfeld's 1958 class lectures and discussions on art education and art therapy. The transcripts serves as explication of Lowenfeld's_ Creative and Mental Growth_, now going into a seventh edition—with posthumous collaborators since the author's death in 1960—translated into all the world's major languages. The experiential basis of Lowenfeld's ideas is revealed through the autobiographical and reflective quality of his (...) lectures and his Socratic dialogs with students. Both his vicarious experience, arising from his erudition, and his immediate experience, stemming from his sensitivity to everyday stimuli, are focused on the problem at hand. The result is a freshness and immediacy as though the author were speaking directly to the reader about mutual concerns. The book presents transcripts of 31 class sessions conducted by Lowenfeld on Art and the Child, Art and the Adolescent, and Art Education Therapy in the year after his election as "Art Educator of the Year" by national Art Education Association. The editor's introduction gives the highlights of Lowenfeld's life and work and the circumstances surrounding the recorded class meetings. The book concludes with a selected bibliography of the works of Viktor Lowenfeld. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:Comment on Hospice of Washington's PolicyJohn A. Robertson (bio)The recent history of medical ethics may accurately be described as a history of coming to terms with personal autonomy and informed consent across the range of medical practice. Nowhere has this recognition been more important than in decisions to withhold or withdraw life-sustaining medical procedures from terminal and chronically ill patients.Despite the widespread acceptance of autonomy in these decisions, many (...) people—physicians, families, and policymakers—have balked at extending it to the withdrawal of artificially supplied fluids and nutrition. The symbolic connotations of food and water have led some persons to perceive cessation of medically-supplied fluids and nutrition to be a cruel, barbarous act, rather than the merciful respect for the dying patient that such withdrawal usually represents.Two recent events might help resolve the controversy, and ensure that decisions about artificial fluid and nutrition are handled like any other medical intervention—according to patient and family choice and patient welfare. One event is the Supreme Court decision in Cruzan (Cruzan v. Director of Missouri Department of Health, 110 S.Ct. 2841, 1990). Although the Supreme Court upheld Missouri's constitutional power to require artificial nutrition for a patient in a persistent vegetative state, its decision was not based on the symbolic importance of artificial fluids and nutrition. No Supreme Court justice saw a significant difference between medically-supplied nutrition and hydration and other medical interventions, thus allowing them to be discontinued either directly or by advance directive on the same basis as other medical interventions.The second event is the publication of the statement of "Philosophy Regarding Medical Intervention to Supply Fluids and Nutrition" by Hospice of Washington (or similar statements by other organizations). This statement is useful and important because it removes the issue of food and water from its symbolic overlay [End Page 139] and places it in the real context of dying hospice patients. It makes clear that the overriding consideration should be benefit to the patient "in accord with the patient's wishes or those of the appropriate surrogate(s) for the patient." Depending on those wishes and their impact on the patient, this position may or may not involve medically-supplied fluids and nutrition.This statement is also helpful in showing the medical complexity of such decisions in terms of their actual effect on dying patients. Rather than an either/or position, it recognizes that fluids may harm a dying patient by increasing discomfort, and that "persons near death do not ordinarily tolerate substantial volumes of enteral feedings." Thus rather than adhere to a symbolically-based position about the meaning of food and water to a dying patient, the important thing is to look to that patient's needs and give fluids or not, as the patient's wishes and situation demand.Fortunately, the law in most jurisdictions will recognize such a position. In those few jurisdictions that have made a fetish of artificial fluids and nutrition, the law should be changed, for the HOW statement makes clear that such a position may actually end up harming dying patients. Patient welfare should be privileged above all else, and patient welfare may often entail that fluids and nutrition not be medically supplied. Even then, however, caregivers will look to patient comfort and remedy dry mouths and lips with lubricants and ice chips.The HOW statement is, in my view, a very useful guideline not only for hospices but for hospitals, too—for any situation in which a patient is terminally ill and soon to die. A somewhat different set of issues arises, however, when the patient is chronically ill and incompetent, and will survive for long periods with medically-supplied fluids and nutrition. Recognition of patient rights in those situation should also permit cessation of fluids and nutrition on the same basis that respirators, antibiotics, and other life-sustaining measures may be withheld. But the withholding of medically-supplied fluids and nutrition from a patient who no longer has interests in surviving in an extremely debilitated condition raises different issues from withholding fluids that could cause such discomfort and nutrition when the patient is imminently dying. In either case, patient... (shrink)

There is growing interest in developing co-operation between adult literacy researchers and practitioners to further research skills and approaches. Canada’s National Literacy Secretariat has recently initiated a series of policy debates that suggested several possibilities: targeted research grants, research internships for practitioners, practical sabbaticals for researchers, support for networking between literacy researchers and practitioners, and joint seminars and workshops between researchers and practitioners. A common theme throughout these discussions is the need to develop critical thinking about both collaborative research and (...) adult literacy. In this paper we discuss two collaborative initiatives between university-based researchers and adult literacy groups in the provinces of British Columbia and Ontario. Each project was based on the notion of “research circles” and specifically designed to enhance research capacity and critical thinking about literacy research. (shrink)

The Secunda pars of the Summa theologiae provides Aquinas's mature and systematic account of human action. The Prima secundae represents his treatment of the moral life "in universali." After treating the end of man, and certain aspects of human action as such, he turns to what he calls the "principles of action." Well over half of the questions of the Prima secundae are devoted to these principles. The principles are divided into intrinsic and extrinsic principles, the latter being law and (...) grace. ;What does Aquinas mean when he calls law an extrinsic principle? And given that it is extrinsic, in just what sense can it be a principle of action without threatening the integrity of voluntary action? ;Many writers in the broader Thomistic tradition have de-emphasized the role of law in the moral life. Others, granting law a substantial role, deny its extrinsic character. A common thread can be discerned in these two positions: namely, an unwillingness or hesitancy to grant law as an extrinsic principle a major and unique role in the moral life. ;Three fundamental points concerning law as an extrinsic principle of action are central to this dissertation. First, for Aquinas law is, and always remains, essentially an extrinsic principle. Second, for Aquinas law is a foundational and essential principle of moral actions; indeed natural law provides the first principles of practical reasoning. Third, this understanding of law as an extrinsic principle does not threaten the voluntary or the profoundly personal character of human action. ;After reviewing the thoughts of some contemporary writers, I examine the nature and kinds of law in Aquinas and then its extrinsic character. A treatment of just how law acts as a real principle, indeed a cause of action, where I study the relation of law and prudence, is finally followed by a consideration of the end of law. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:Reviewed by:Intimacy or Integrity: Philosophy and Cultural DifferenceDavid Jones and John A. SweeneyIntimacy or Integrity: Philosophy and Cultural Difference. By Thomas P. Kasulis. Honolulu: University of Hawai'i Press, 2002. Pp. xii + 183. Paper $14.95.Back in the early days of cross-cultural inquiry, scholars gained some territory in the understanding of cultural difference by focusing their attention on the distinction between the individualistic and the collective. Asians, especially East (...) Asians, were seen as motivated by collectivism, whereas Westerners were firmly rooted in individuality. This distinction afforded some comprehension of cultural difference and served a limited purpose in those early days of trying to understand Asia as a whole and the vast reach of difference among various Asian groups. However, we quickly outgrew our dependence on this distinction, although we continued to insist on making use of it. Thomas Kasulis offers us a new heuristic in his recent book Intimacy or Integrity: Philosophy and Cultural Difference, which is based on his 1998 Gilbert Ryle Lectures at Trent University.The book begins with a series of anecdotes, which is most fitting for what the author has in mind. These seemingly simple stories of cultural misunderstanding actually point to profound differences between Asian and Western cultural perspectives. Kasulis, however, rightly extends the boundaries of his discussion to traverse not only Asian/Western differences but also variations between cultures and subcultures as well. The thesis of the book addresses the too simplistic notion that Asians are simply more collectivist than their Western counterparts, and this thesis applies as well to differences within the structure of any culture's grand narrative. Put directly, the thesis is that there are recursive cultural patterns that orient themselves in two basic ways: "intimacy" and "integrity." These patterns reiterate themselves into complex theoretical manifestations through understandings of fact/value, what is and what should be (p. 11).Aware that he might easily fall into the old trap of a simplistic differentiating between "them and us," Kasulis is quick to point out that "it is unlikely that any culture is ever a perfect example of either an intimacy-dominant or integrity-dominant culture" (p. 11). In other words, "intimacy" and "integrity" (unlike collectivism and individualism) are both positive terms that continually, and recursively, foreground and background themselves in any given culture. For example, Americans, with their penchant for individuality and the benefits arising from it, such as the notion of rights, also value and understand intimacy as a feeling that is primary to one's being either a member of a family, a member of a group, or a citizen of a country. And to think that individuality has no value whatsoever in Asia or that there are no "individuals" in Asia is just being simpleminded. These two different ways of relating—intimacy and integrity—are explored in connection to the key relations of self/world, self/other, knower/known, thing/thing, and so forth (p. 13) throughout the book, as reflected in the chapter titles: "Cultural Orientations," "What Is Intimacy?" "What [End Page 603] Is Integrity?" "Intimacy and Integrity as Worldviews: Epistemology, Analysis and Argument, and Metaphysics," "The Normative Dimensions of Intimacy and Integrity: Aesthetics, Ethics, and Politics," and "Intercultural Conflict: When Intimacy and Integrity Collide."An important concern of this book, and an issue that is often overlooked by philosophers, is that philosophy is both a product and a producer of culture. If culture even becomes a matter of philosophical discussion, it is often cast in terms of a "philosophy of culture," that is, a part of our understanding of the role that culture plays in the more universal context of human existence (p. 13). Kasulis reminds us, however, of another (and perhaps more important) dimension of the study of what he calls "cultural philosophy," and that is that "philosophy itself is a cultural enterprise" (p. 14). By viewing philosophy in this way philosophers are able to check their tendency to believe erroneously that philosophy is a discipline that can achieve an understanding of, or even attempt to search for, universal, eternal, and transcultural truths. Kasulis points out that this too is a "tendency... related to cultural conditions" (p. 14); hence, "philosophy and... (shrink)

This chapter argues that scientific and philosophical progress in our understanding of the living world requires that we abandon a metaphysics of things in favour of one centred on processes. We identify three main empirical motivations for adopting a process ontology in biology: metabolic turnover, life cycles, and ecological interdependence. We show how taking a processual stance in the philosophy of biology enables us to ground existing critiques of essentialism, reductionism, and mechanicism, all of which have traditionally been associated with (...) substance ontology. We illustrate the consequences of embracing an ontology of processes in biology by considering some of its implications for physiology, genetics, evolution, and medicine. And we attempt to locate the subsequent chapters of the book in relation to the position we defend. (shrink)

Word Order Universals is a detailed account of word order universals and their role in theories of historical change. The starting point is the Greenberg data set, which is comprised of a sample of 142 languages for certain limited co-occurrences of basic word orders, and a 30-language sample for more detailed information. In the Language Index, the 142 have been expanded to some 350 languages. Using the original Greenberg samples and the Expanded Sample, an alternative set of descriptive word order (...) statements is provided. Comprised of eight chapters, this book begins with an introduction to the theory of word order universals, encompassing topics such as word order variation across languages and theories of universal grammar. The reader is then introduced to the work of Joseph Greenberg and Theo Vennemann on word order universals; implicational universals in Greenberg's data and the Expanded Sample; and the predictions made by implicational and distributional universals for word order change. Reformulated universals for historical reconstruction are also discussed, along with some laws of reconstruction derived from synchronic universals. The final chapter is devoted to the Expanded Sample, with particular reference to its quantities as well as its typological and genetic classification. This monograph will be a useful resource for specialists in grammar and linguistics. (shrink)

Sympathy for animals is regarded by many thinkers as theoretically disreputable. Against this I argue that sympathy appropriately underlies moral concern for animals. I offer an account of sympathy that distinguishes sympathy with from sympathy for fellow creatures, and I argue that both can be placed on an objective basis, if we differentiate enlightened from folk sympathy. Moreover, I suggest that sympathy for animals is not, as some have claimed, incompatible with environmentalism; on the contrary, it can ground environmental concern. (...) Finally, I show that the traditional concept of anthropomorphism has no coherent basis, and I argue that the attempt to prove that animals lack thoughts is both unsuccessful and irrelevant to sympathy for languageless creatures.

The sense of agency is the perception of willfully causing something to happen. Wegner and Wheatley proposed three prerequisites for SA: temporal contiguity between an action and its effect, congruence between predicted and observed effects, and exclusivity . We investigated how temporal contiguity, congruence, and the order of two human agents’ actions influenced SA on a task where participants rated feelings of self-agency for producing a tone. SA decreased when tone onsets were delayed, supporting contiguity as important, but the order (...) of the agents’ actions also mattered. Relative contiguity was the main determinant of SA, as delayed tones were usually attributed to the most recent action. This was unaffected by contingencies between the two actors’ actions , showing that contiguity has a powerful influence on SA, even during joint action in the presence of other cues. (shrink)
