We argue for an example of based on Diamond and Carey's (1986) work on expertise and recognition, which is not made use of in The Origin of Concepts. This mechanism for perceptual learning seems to have all the necessary characteristics in that it is innate, domain-specific (requires stimulus sets possessing a certain structure), and demonstrably affects categorisation in a way that strongly suggests it will influence concept formation as well.

I argue that the dual-process account of human learning rejected by Mitchell et al. in the target article is informative and predictive with respect to human behaviour in a way that the authors' purely propositional account is not. Experiments that reveal different patterns of results under conditions that favour either associative or rule-based performance are the way forward.

Argues that despite claims of self-styled 'postmodernists of resistance', postmodernism provides neither a viable educational politics nor a foundation for effective radical educational practice. In place of postmodernism, the bookoutlines a 'politics of human resistance' which puts the challenge to capitalism and its attendant inequalities firmly on the agenda of educational theory, politics and practice.

Some argue the common practice of inferring multiple processes or systems from a dissociation is flawed. One proposed solution is state-trace analysis, which involves plotting, across two or more conditions of interest, performance measured by either two dependent variables, or two conditions of the same dependent measure. The resulting analysis is considered to provide evidence that either a single process underlies performance or there is evidence for more than one process. This article reports simulations using the simple recurrent network in (...) which changes to the learning rate produced state-trace plots with multiple functions. We also report simulations using a single-layer error-correcting network that generate plots with a single function. We argue that the presence of different functions on a state-trace plot does not necessarily support a dual-system account, at least as typically defined ; it can also indicate variation in a single parameter within theories generally considered to be single-system accounts.

The book deals with the notion of Downward Causation from a wide array of perspectives, including physics, biology, psychology, social science, communication studies, text theory, and philosophy. The book includes proponents as well as opponents discussing the validity of the notion.

This paper argues that episodic thoughts are always unconscious. Whether consciousness is understood in terms of global broadcasting/widespread accessibility or in terms of non-interpretive higher-order awareness, the conclusion is the same: there is no such thing as conscious thought. Arguments for this conclusion are reviewed. The challenge of explaining why we should all be under the illusion that our thoughts are often conscious is then taken up.

This study concerns the ideas of one particular philosopher, Henri Bergson, whose views of time, intuition, and creativity have had a significant impact on art, literature, and the humanities, both in his time and in our own. Although it is generally recognized that Bergson's ideas have significantly impacted the arts and the humanities, it has not been recognized how they have also had a creative influence on the sciences as well. Nor has it been realized that this was one of (...) his most basic contentions. Bergson's conception of intuition--his fundamental insight into reality--was not limited to fugitive insights into human existence. By realizing previously unsuspected possibilities for research and discovery, his endeavors were also meant to make possible new advances in the sciences. If it enabled his cousin by marriage, Marcel Proust, to explore human memory in depth, it also inspired psychologists like Daniel Schachter to use Bergson's ideas to make real contributions to contemporary memory science. If his notion of creative evolution brought many thinkers to a belief in human creative freedom, it brought others (notably Alexis Carrel and Pierre Lecomte de Noüy) to a scientific study of biological time. Among his successful speculations was the theory of the Big Bang cosmology. 'Getting Bergson Straight' shows many points at which Bergson's ideas anticipated future developments in the sciences. This was seen clearly by the Nobel Prize-winning physicist Luis de Broglie who viewed Bergson's physics as presaging quantum physics. Thus, the text is well situated for arts, humanities, social science, and natural science classrooms studying creative thinking and/or intellectual history. (shrink)

This paper is about the good side of modal logic, the bad side of modal logic, and how hybrid logic takes the good and fixes the bad.In essence, modal logic is a simple formalism for working with relational structures . But modal logic has no mechanism for referring to or reasoning about the individual nodes in such structures, and this lessens its effectiveness as a representation formalism. In their simplest form, hybrid logics are upgraded modal logics in which reference to (...) individual nodes is possible.But hybrid logic is a rather unusual modal upgrade. It pushes one simple idea as far as it will go: represent all information as formulas. This turns out to be the key needed to draw together a surprisingly diverse range of work . Moreover, it displays a number of knowledge representation issues in a new light, notably the importance of sorting. (shrink)

Developmental systems theory is a general theoretical perspective on development, heredity and evolution. It is intended to facilitate the study of interactions between the many factors that influence development without reviving `dichotomous' debates over nature or nurture, gene or environment, biology or culture. Several recent papers have addressed the relationship between DST and the thriving new discipline of evolutionary developmental biology. The contributions to this literature by evolutionary developmental biologists contain three important misunderstandings of DST.

There have been many claims that quantum mechanics plays a key role in the origin and/or operation of biological organisms, beyond merely providing the basis for the shapes and sizes of biological molecules and their chemical affinities. These range from Schr¨odinger’s suggestion that quantum fluctuations produce mutations, to Hameroff and Penrose’s conjecture that quantum coherence in microtubules is linked to consciousness. I review some of these claims in this paper, and discuss the serious problem of decoherence. I advance some further (...) conjectures about quantum information processing in bio-systems.

It may be seen from the foregoing that Pauline's existence is multiply jeopardized; or rather, that my right to use 'Pauline' as a name, the way I said I was going to, is very doubtful, for I agree with Parmenides that one cannot name what is not there to be named. The words I have used to describe Pauline's various perils are full of what Ryle aptly called "systematically misleading expressions"; but we need not worry about that for the moment-enough (...) for now if the words succeed in bringing the various cases before our minds--and we can tidy up our language as we come to see things more clearly.

As a preliminary step to beginning to assess the usefulness of clinical vignettes to measure ethical sensitivity in undergraduate medical students, five clinical vignettes with seven to nine ethical issues each were created. The ethical issues in the vignettes were discussed and outlined by an expert panel. One randomly selected vignette was presented to first, second and third year students at the University of Toronto as part of another examination. The students were asked to list the issues presented by the (...) patient problem. Responses from 281 students were obtained. These students identified an average of 2.72 ethical issues per vignette. Each response was classified under the domains of autonomy, beneficence and justice. Comparisons were made between classes and between vignettes. There was considerable variation between classes and the responses to different vignettes seem to indicate that different vignettes measure the various domains in different ways. It does appear that the use of vignettes is one way to measure aspects of ethical sensitivity in medical students but more study is required to clarify exactly what is being measured. (shrink)

An instrument to assess 'ethical sensitivity' has been developed. The instrument presents four clinical vignettes and the respondent is asked to list the ethical issues related to each vignette. The responses are classified, post hoc, into the domains of autonomy, beneficence and justice. This instrument was used in 1990 to assess the ethical sensitivity of students in all four medical classes at the University of Toronto. Ethical sensitivity, as measured by this instrument, is not related to age or grade-point average. (...) Sensitivity increases between the 1st and 2nd year and then decreases throughout the rest of undergraduate medical training, such that the 4th-year students identify fewer issues than those entering medical school. Students expressing a career choice of family medicine identify more issues than their peers. Several problems with the use of the instrument and the interpretation of the data were found. Nonetheless, these findings, if reproducible, are important and their meaning needs further discussion. (shrink)

Richard Taylor was born in Charlotte, Michigan on 5 November 1919. He received his A. B. from the University of illinois in 1941, his M. A. from Oberlin College in 1947, and his Ph. D. from Brown University in 1951. He has been William H. P. Faunce Professor of Philosophy at Brown University, Professor of Philosophy (Graduate Faculties) at Columbia University, and Professor of Philosophy at the University of Rochester. He is the author of about fifty articles and of five (...) philosophical books. This volume consists of essays presented to Richard Taylor on the occa sion of his sixtieth birthday. Some of the contributors have been Taylor'S students; some have been his colleagues; and all have been, and continue to be, his admirers. I have made several attempts to articulate what it is I (I would not presume to speak for anyone else) admire about Richard Taylor: (1) There is a particular 'flavor' to Taylor's philosophical writing and con versation that is wholly delightful. Like any other flavor, it can be tasted and enjoyed and remembered but never adequately described. (If there should be someone who has picked up this book who does not know what I mean, I recommend that he read the chapter on 'God' in Taylor's Metaphysics. ) (2) Taylor is a masterful dialectician.

Open peer commentary on the article “Perception-Action Mutuality Obviates Mental Construction” by Martin Flament Fultot, Lin Nie & Claudia Carello. Upshot: In my view, the clash between ecological psychology, enactivism, and constructivism in general has more to do with irreconcilable metaphysical and theoretical incommensurabilities than disagreements about specific mechanisms or processes of perception. Even with mutual enabling of action and perception, some internal process of self-modification is still needed if novel behavior is to be adequately explained.

Studies in Stoicism contains six unpublished and seven republished essays, the latter incorporating additions and changes which Brunt wished to be made. The papers have been integrated and arranged in chronological order by subject matter, with an accessible lecture to the Oxford Philological Society serving as Brunt's own introduction.

This article examines the origin of experiential organization, especially whether it is salient or selective. Aron Gurwitsch believes it is salient and William James that it is selective. I argue that Gurwitsch is right, and recount his argument and his critique of James, but I also pose my own critique and critical questions on the issue. -/- Gurwitsch's argument attempts to show that the organization of consciousness is not arbitrary or merely selected in some way by the subject. He claims (...) that when consciousness is organized it is found as already organized. -/- This is important for Gurwitsch's philosophical system because if he can establish that consciousness is always originally organized, then his famous claim that the theme, thematic-field, margin structure of consciousness is an invariant patterning impervious to the subject's whim, mood, or possible noetic training, is protected at the very start.

P. Kyle Stanford - The Manifest Connection: Causation, Meaning, and David Hume - Journal of the History of Philosophy 40:3 Journal of the History of Philosophy 40.3 339-360 The Manifest Connection: Causation, Meaning, and David Hume P. Kyle Stanford 1. Introduction exciting recent hume scholarship has challenged the traditional view that Hume's theory of meaning leads him to deny the very intelligibility or coherence of supposing that there are objective causal powers or intrinsic necessary connections between causally related entities. Influential (...) recent interpretations have variously held that Hume himself accepted the existence of such powers and connections, that he was genuinely agnostic about them, or that he denied their existence while nonetheless holding it to be a perfectly coherent possibility, indeed one that we routinely think actual. In this paper I will argue against all three of these lines of interpretation and in favor of what I consider a neglected alternative: that Hume rejects the existence of objective necessary connections or causal powers as literally incoherent or meaningless, but on subtle and sophisticated semantic grounds, rather than simplistic ones. I find support for this semantic reading and against the alternatives not only in passages whose significance to the debate is widely appreciated, but also in Hume's discussions "Of Liberty and Necessity" and "Of the Immateriality of the Soul."

Philosophers often distinguish in some way between two senses of life's meaning. Paul Edwards terms these a ‘cosmic’ and ‘terrestrial’ sense. The cosmic sense is that of an overall purpose of which our lives are a part and in terms of which our lives must be understood and our purposes and interests arranged. This overall purpose is often identified with God's divine scheme, but the two need not necessarily be equated. The terrestrial sense of meaning is the meaning people find (...) in their own lives apart from the place of their lives in any ultimate end or context. (shrink)

The criminal law presently distinguishes between actions and omissions, and only rarely proscribes failures to avert consequences that it would be an offense to bring about. Why? In recent years it has been persuasively argued by both Glover and Bennett that, celeris paribus, omissions to prevent a harm are just as culpable as are actions which bring that harm about. On the other hand, and acknowledging that hitherto “lawyers have not been very successful in finding a rationale for it,” Tony (...) Honoré has sought to defend the law's differential treatment. He proposes a “distinct-duties theory” that in addition to the general duties we owe to everyone, we also owe distinct duties to a more limited collection of people and associations, specified by features of our relationship with them. Where a distinct duty holds, breach by omission may well be no better than breach by positive action. But absent a distinct duty, omissions, per Honoré, are less culpable. They are mere failures to intervene and improve or rectify things, whereas actions are positive interventions which make things worse. And, thus, the law has good reason to differentiate between them. (shrink)
