We analyze naturally occurring datasets from student use of educational technologies to explore a long-standing question of the scope of transfer of learning. We contrast a faculty theory of broad transfer with a component theory of more constrained transfer. To test these theories, we develop statistical models of them. These models use latent variables to represent mental functions that are changed while learning to cause a reduction in error rates for new tasks. Strong versions of these models provide a common (...) explanation for the variance in task difficulty and transfer. Weak versions decouple difficulty and transfer explanations by describing task difficulty with parameters for each unique task. We evaluate these models in terms of both their prediction accuracy on held-out data and their power in explaining task difficulty and learning transfer. In comparisons across eight datasets, we find that the component models provide both better predictions and better explanations than the faculty models. Weak model variations tend to improve generalization across students, but hurt generalization across items and make a sacrifice to explanatory power. More generally, the approach could be used to identify malleable components of cognitive functions, such as spatial reasoning or executive functions. (shrink)

This paper examines Foucault's history of the ancient practices of the self. It suggests that his historical reconstruction usefully distinguishes quite different models of self-cultivation in antiquity, and in doing so helps us to identify and understand the parameters and ambitions of much nineteenth-century German philosophy, especially the ethics of self-cultivation Nietzsche formulates in his middle works. However, it also shows how FoucaultÕs casual formulation of an 'aesthetic of existence' is seriously misleading as a guide to the ancient practices of (...) the self, most notably the Stoic tradition. This paper argues that Foucault does not properly take into account how Stoicism conceives the desire to flee from or break with oneself, which Foucault places at the centre of his own askesis, as a pathological agitation that requires therapy. From the Stoic perspective, in other words, Foucault's askesis of constantly losing oneself is symptomatic of a failure to care for oneself. (shrink)

Intuitively it has seemed to many that our concepts conscious state and conscious creature are sharp rather than vague, that they can have no borderline cases. On the other hand, many who take conscious states to be identical to, or realized by, complex physical states are committed to the vagueness of those concepts. In the paper I argue that conscious state and conscious creature are sharp by presenting four necessary conditions for conceiving borderline cases in general, and showing that some (...) of those conditions cannot be met with conscious state. I conclude that conscious state is sharp, and the conclusion is then extended to conscious creature. The paper ends with a brief discussion of some implications. (shrink)

In early 1864, disappointed by the response to his previous work, the young Manchester academic W. Stanley Jevons announced that he was undertaking a study of the so-called coal question: ‘A good publication on the subject would draw a good deal of attention … it is necessary for the present at any rate to write on popular subjects’. When Jevons's The Coal Question was published in April 1865, however, it received comparatively little attention and sales were slow. Jevons and his (...) publisher, Alexander Macmillan, then began sending complimentary copies to luminaries such as Sir John Herschel and Alfred Tennyson. In February 1866 the marketing campaign produced its first substantial return. Macmillan had sent CQ to William Gladstone who responded with letters to both Macmillan and Jevons, noting that the book had strengthened his ‘conviction’ on the necessity for reducing the National Debt. In April, John Stuart Mill praised CQ in the House of Commons, calling for action on the Debt and, three weeks later, as Chancellor of the Exchequer, Gladstone introduced the budget using half his speech to examine the Debt situation and referring to CQ in support for a proposed measure of Debt reduction. With the extensive publicity given to CQ following Mill's speech and the budget, Jevons had achieved his objective in writing the text which went into a second edition in 1866. On the face of it, CQ 's success was due to its effect of introducing a change in budget policy and this is the impression given by some accounts of the episode. (shrink)

While "Consciousness Explained" has received an enormous amount of attention since its publication, there is still little agreement on what Dennett’s account of consciousness is. Most interpreters treat his view as an instance of one or another of the standard ontological positions (functionalism, behaviorism, eliminativism, instrumentalism). I believe a different metaphysical account underlies Dennett’s view, one that is important though ill-understood. In the paper I attempt to point in the direction of a proper characterization of that account through the use (...) of two illustrative examples. A ten-point story that applies to the examples is developed, and it is suggested that the story applies equally well to Dennett’s view of consciousness. (shrink)

Book Gamma of Aristotle’s Metaphysics contains a vigorous defense of the principle of non-contradiction (PNC). A chief part of Aristotle’s strategy is to attack those, such as Heraclitus and Protagoras, who are said to deny the principle. Commentators have found a number of logical and historical problems with Aristotle’s arguments, but none are more troubling than those he deploys against Protagoras. Midway through Gamma 4, and throughout Gamma 5, he represents Protagoras not as simply denying PNC but rather as asserting (...) the contrary of the principle. The latter, the proposition that every thing has every property and its negation, I call the strong denial of PNC. In particular, Aristotle argues that Protagoras is committed to strong denial because of ‘Protagorean’ relativism – the doctrine that if something appears to be the case, then it is the case. This paper provides a reconstruction of Aristotle’s arguments in Gamma 4 and 5, and suggests that the second argument may infact hold against the Protagorean. (shrink)

Can humans acquire knowledge of ultimate reality, even significant or comprehensive knowledge? I argue that for all we know we can, and that is so whether ultimate reality is divine or non-divine. My strategy involves arguing that we are ignorant, in the sense of lacking public or shared knowledge, about which possibilities, if any, obtain for humans to acquire knowledge of ultimate reality. This follows from a deep feature of our epistemic situation—that our current psychology strongly constrains what we can (...) conceive about the extent to which human intellectual and other psychological capacities might develop in the future. This mean that many possibilities for such development remain open to us epistemically, including the possibility that we might come to understand vastly more about ultimate reality than we currently do, even if ultimate reality is divine. I also argue that there is room to rationally hope that that is so. (shrink)

Wedin discusses Aristotle's claims in Metaphysics Zeta 6 that the essence of a thing is to be sought among its per se attributes, and that each thing that is primary and spoken of per se, e.g. primary substance, is the same as its essence. Wedin argues that the Zeta 6 Thesis, i.e. that the essence of a thing is the thing's immediate essence, is a crucial requirement of the explanatory role of essence as the substance of c‐substances. According to Wedin, (...) Aristotle introduces this requirement in order to establish that a thing's essence cannot depend on another essence. Form must be the essence; if form cannot explain the nature of the thing of which it is the form, there would be the threat of a regress of explanatory forms. At the end of the chapter, Wedin considers the problem that the identity of a thing and its essence is a requirement that can be met by non‐substance items, but he denies that this leads to a dilution of the conception of substance.

This remarkable collection of period photographs details day-to-day life and changing times in the Deep South. Draffus Lamar Hightower, 1899-1993, spent most of his life in Barbour County, Alabama. For many years he was the owner of a Chevrolet dealership, but he had another occupation as well. From his youth, he was fascinated with photography, and for fifty years he experimented with the craft both technically and artistically. Hightower, while participating fully in the 20th century, was also acutely aware of (...) the passing of the heritage of the last one. From the early 1920s to the late 1960s, he made thousands of negatives of people, events, landscapes, objects, and buildings in Barbour County. His photographs are reminiscent of the documentary work of Walker Evans, Berenice Abbott, and other great 20th-century American photographers. Hightower created an incredibly complete and vivid record of the life of a rural Alabama county during a period of profound change-documenting everything from birthday parties and political rallies to farm scenes and the demolition of historic buildings so that future generations would not forget the world of their forebears. In 1990, Michael Thomason, historian and photographic archivist, began the long process of reviewing Hightower's collection of photographs, interviewing family and friends, and salvaging and printing the negatives, which by that time had begun to deteriorate. Thomason restored and printed 195 photographs and prepared accompanying essays that not only reveal the technical details of Hightower's labor of love but also tell the story of the human and economic changes in Barbour County during this period.

This paper considers I) whether Aristotle's notion of form is 'compositionally plastic' and II) whether matter is in any way to be included in the form of natural things. It pursues (I) and (II) with respect to two texts only: De Anima I-2's socalled definition of anger and the notorious young Socrates passage from Metaphysics VII.11. Neither passage supports indusion of anything material in the form and both are consistent with compositional plasticity. To thus extent the support what I call (...) the purification of form.

Wedin considers the relation between the ontological commitment in the Categories and the semantical theory of underlying ontological configurations for standard categorical statements. According to Wedin, Aristotle's fourfold division of beings, which divides things according to whether they are, or are not, said of, and/or present in a subject, is a meta‐ontology that is concerned with beings per se, i.e. the fundamental things that are. Wedin explains that the primacy of c‐substance involves an asymmetry in the relation between c‐substance and (...) everything else, or between the substantial and the nonsubstantial. This is because there is an ontological dependence of non‐substances, and also of secondary substances, on substances: everything is either said of, or in, primary substance. The argument of this chapter, then, is that the world of the Categories is a world of individuals: all ontological relations needed for semantics can be accommodated by appeal to individuals only.

Anyone with more than casual interest in Aristotle's Categories knows the convention that "predicated of" ["κατηγορεἳται"] marks a general relation of predication while "said of" ["λέγεται"] is reserved for essential predication. By "convention" I simply mean to underscore that the view in question ranks as the conventional or received interpretation. Ackrill, for example, follows the received view in holding that only items within the same category (not arbitrarily, of course) can stand in the being-said-of relation and, thus, that only secondary (...) substances can be said of primary substances. Despite its long received status the convention has never received a fully comprehensive examination and defense. In fact such an account is needed because, while enjoying considerable textual support, certain passages of the Categories appear to clash with the convention. My aim in this paper is, first, to develop and defend the standard interpretation, as I shall call it. Since the standard interpretation has lately been challenged in a closely argued article by Russell Dancy, my defense will proceed partly with an eye to his criticisms. Having met these, I go on to raise some difficulties with the rather unorthodox reading Dancy gives the Categories. The crucial point here turns out to be what Aristotle understands by a paronym.

Wedin argues, against prevailing opinions, that Aristotle's account of homonymy, synonymy, and paronymy, with which the Categories begins, must be understood as an integral part of the treatise. The three ‘onymyies’, as Wedin calls them, are grouping principles, or one‐over‐many principles, that each collect a number of items under a single term. Wedin focuses on synonymy in particular, because it enables Aristotle to construct a theory of the fundamental kinds of things that are, and as such provides the basis for (...) the system of the categories. For Wedin, the Categories is not just concerned with classification but also with ontology and semantics: it offers a theory about the underlying ontological implications of standard categorical statements, with the aim of determining what must exist, and in what relations these things must stand, in order for the statements to be true.

This article diagnoses the problem of plagiarism in academic books and articles in the disciplines of philosophy and theology. It identifies three impediments to institutional reform. They are: (1) a misplaced desire to preserve personal and institutional reputations; (2) a failure to recognize that attribution in academic writing admits of degrees; and (3) a disproportionate emphasis on the socalled “intention to plagiarize.” A detailed case study provides an illustration of the need for institutional reform in the post-publication processes in the (...) disciplines of philosophy and theology.

That consciousness is composed of simple or basic elements that combine to form complex experiences is an idea with a long history. This idea is approached through an examination of our “picture” or conception of consciousness . It is argued that CC commits us to a certain abstract notion of simple experiential events, or simples, and that traditional critiques of simple elements of experience do not threaten simples. To the extent that CC is taken to conform to how consciousness really (...) is, therefore, the concept of simples must be treated in kind. (shrink)

In the eleventh chapter of Matthew’s Gospel, Jesus says to the inhabitants of Bethsaida and Corozain: “If the miracles worked in you had taken place in Tyre and Sidon, they would have repented long ago in sackcloth and ashes”. Passages like this support a scriptural argument for God’s knowledge of counterfactuals about created individuals. In the sixteenth century, Jesuits and Dominicans vigorously debated about how to explain this knowledge. The Jesuits, notably Luis de Molina and Francisco Suarez, argued that the (...) basis for this knowledge lies primarily in the divine intellect: counterfactuals about free creatures are primitive truths known to God by virtue of the immensity of his intellectual power. Their Dominican opponents, notably Domingo Bañez and Diego Alvarez, held that this knowledge is simply God’s knowledge of his own decrees, by which he determines the truth value of all contingent propositions, including counterfactuals.

An argument is offered for this conditional: If our current concept conscious state is sharp rather than vague, and also correct , then common versions of familiar metaphysical theories of consciousness are false--?namely versions of the identity theory, functionalism, and dualism that appeal to complex physical or functional properties in identification, realization, or correlation. Reasons are also given for taking seriously the claim that our current concept conscious state is sharp. The paper ends by surveying the theoretical options left open (...) by the concept's sharpness and the truth of the conditional argued for in the paper. (shrink)

It is widely assumed that ‘ consciousness ’ is multiply ambiguous within the consciousness literature. Some alleged senses of the term are access consciousness, phenomenal consciousness, state consciousness, creature consciousness, introspective consciousness, self consciousness, to name a few. In the paper I argue for two points. First, there are few if any good reasons for thinking that such alleged senses are genuine: ‘ consciousness ’ is best viewed as univocal within the literature. The second point is that researchers would do (...) best to avoid the semantics of ‘ consciousness ’, since resorting to “semantic ascent” typically serves no clear purpose in the case of consciousness, and confuses matters more than anything else.

Two criticisms of Davidson's argument for monism are presented. The first is that there is no obvious way for the anomalism of the mental to do any work in his argument. Certain implicit premises, on the other hand, entail monism independently of the anomalism of the mental, but they are question-begging. The second criticism is that even if Davidson's argument is sound, the variety of monism that emerges is extremely weak at best. I show that by constructing ontologically ``hybrid'' events (...) that are consistent with the premises and assumptions of Davidson's argument, but entail ontological dualism. (shrink)

Leibniz states that 'metaphysics is natural theology', and this is especially true of his metaphysics of modality. In this book, Michael V. Griffin examines the deep connection between the two and the philosophical consequences which follow from it. Grounding many of Leibniz's modal conceptions in his theology, Griffin develops a new interpretation of the ontological argument in Leibniz and Descartes. This interpretation demonstrates that their understanding God's necessary existence cannot be construed in contemporary modal logical terms. He goes on (...) to develop a necessitarian interpretation of Leibniz, arguing that Leibniz, like Spinoza, is committed to the thesis that everything actual is metaphysically necessary, but that Leibniz rejects Spinoza's denial of God's moral perfection. His book will appeal to scholars of early modern philosophy and philosophers interested in modal metaphysics and the philosophy of religion. (shrink)

This paper raises some difficulties with the strategy suggested in Robert Nozick’s Philosophical Explanations for explaining why there is something rather than nothing. I am concerned less with his adoption of an egalitarian, as opposed to inegalitarian, explanatory stance (the net effect of which is to detach for independent consideration the question, “Why is there something?”) than with his use of a crucial assumption in reasoning from the egalitarian point of view. I argue that this assumption, that all possibilities exist, (...) is fatally ambiguous, that the persuasiveness of Nozick’s reasoning depends on at once assuming and blurring the difference between the predicates “does not exist” and “nonexists” and that the attempt to wed a priori reasoning and a posteriori (mystical) practice fails.

From the “deep” ecological perspective, there is a dualism between an ecocentric and an anthropocentric perspective, and this dualism is reflected in the ideal of the bureaucratic experience. The bureaucrat lives by the myth of the human ability to control nature. An eco-myth is evolving that can offer one means of transcending the dominant bureaucratic mythic experience. This eco-myth movestoward a positive and sensitive human relationship with nature—a collective experience that values nature on its own terms and not as standing (...) reserve. This position is no less mythic than the one it is replacing, but it is a better myth, because, being non-dualist, it offers the prospect of a political society in harmony with nature. (shrink)
