This book presents a detailed analysis of three ancient models of spatial magnitude, time, and local motion. The Aristotelian model is presented as an application of the ancient, geometrically orthodox conception of extension to the physical world. The other two models, which represent departures from mathematical orthodoxy, are a "quantum" model of spatial magnitude, and a Stoic model, according to which limit entities such as points, edges, and surfaces do not exist in (physical) reality. The book is unique in its (...) discussion of these ancient models within the context of later philosophical, scientific, and mathematical developments. (shrink)

Researchers typically define animal signaling as morphology or behavior specialized for transmitting encoded information from a signaler to a perceiver. Although intuitively appealing, this conception is inherently metaphorical and leaves concepts of both information and encoding undefined. To justify relying on the information construct, theorists often appeal to Shannon and Weaver’s quantitative definition. The two approaches are, however, fundamentally at odds. The predominant definition of animal signaling is thus untenable, which has a number of undesirable consequences for both theory and (...) practice in the field. Theoretical problems include conceptual circularity and running afoul of fundamental evolutionary principles. Problems in empirical work include that research is often grounded in abstractions such as signal honesty and semanticity, and thereby distracted from more basic and concrete factors shaping communication. A revised definition is therefore proposed, making influence rather than transmission of encoded information the central function of animal signaling. This definition is conceptually sound, empirically testable, and inclusive, yet bounded. Implications are considered in both theoretical and empirical domains. (shrink)

In this article we address Emile Durkheim's theory that norms and values become more generalized and abstract in a society as it becomes more complex and differentiated. To test Durkheim's theory we examine etiquette manuals—the common texts that define normative manners and morals in American society. We perform a deductive content analysis on past and present etiquette manuals to understand what changes have occurred regarding shifting behavioral norms and values over time. Our findings suggest that a change has occurred in (...) the presentation and language of contemporary etiquette manuals, reflecting a greater change in the normative order. We find—as Durkheim would expect—that three main shifts have occurred: a shift from specific to general expectations for behavior in social settings, a shift from demanding to more suggestive rules of behavior in social situations, and a weakening in the severity of sanctions for breaches of etiquette.

The right-wing populism ascendant today is a symptom of the failure of progressive politics. Central to this failure is the uncritical embrace of a neo-liberal version of globalization that benefits those at the top but leaves ordinary citizens feeling disempowered. Progressive parties are unlikely to win back public support unless they learn from the populist protest that has displaced them —not by replicating its xenophobia and strident nationalism, but by taking seriously the legitimate grievances with which these ugly sentiments are (...) entangled. These grievances are not only economic but also moral and cultural; they are not only about wages and jobs but also about social esteem. (shrink)

T. M. Scanlon has revived a venerable tradition according to which something's being good consists in its being such that there is a reason to respond positively towards it. He has presented novel arguments for this thesis. In this article, I first develop some refinements of the thesis with a view to focusing on intrinsic value in particular, then discuss the relation between the thesis and consequentialism, then critically examine Scanlon's arguments for the thesis, and finally turn to the question (...) whether we should reject the thesis on the grounds that, when there is a reason to respond positively towards something, this is so because the thing in question is good. Two appendices follow. In the first, I discuss whether it is good to do right. In the second, I discuss whether an act's being wrong provides a reason not to do it. (shrink)

The fitting-attitudes analysis of value, which states that something's being good consists in its being the fitting object of some pro-attitude, has recently been the focus of intense debate. Many objections have been levelled against this analysis. One objection to it concerns the ‘challenge from partiality’, according to which it can be fitting to display partiality toward objects of equal value. Several responses to the challenge have been proposed. This paper criticizes these and other responses and then offers a response (...) that, it is claimed, solves the challenge. (shrink)

How does our understanding of the reality (or lack thereof ) of race as a category of being affect our understanding of racism as a social phenomenon, and vice versa? How should we envision the aims and methods of our struggles against racism? Traditionally, the Western political and philosophical tradition held that true social justice points toward a raceless future--that racial categories are themselves inherently racist, and a sincere advocacy for social justice requires a commitment to the elimination or abolition (...) of race altogether. This book focuses on the underlying assumptions that inform this view of race and racism, arguing that it is ultimately bound up in a "politics of purity"--an understanding of human agency, and reality itself, as requiring all-or-nothing categories with clear and unambiguous boundaries. Racism, being organized around a conception of whiteness as the purest manifestation of the human, thus demands a constant policing of the boundaries among racial categories. Drawing upon a close engagement with historical treatments of the development of racial categories and identities, the book argues that races should be understood not as clear and distinct categories of being but rather as ambiguous and indeterminate (yet importantly real) processes of social negotiation. As one of its central examples, it lays out the case of the Irish in seventeenth-century Barbados, who occasionally united with black slaves to fight white supremacy--and did so as white people, not as nonwhites who later became white when they capitulated to white supremacy. Against the politics of purity, Monahan calls for the emergence of a "creolizing subjectivity" that would place such ambiguity at the center of our understanding of race. The Creolizing Subject takes seriously the way in which racial categories, in all of their variety and ambiguity, situate and condition our identity, while emphasizing our capacity, as agents, to engage in the ongoing contestation and negotiation of the meaning and significance of those very categories.

This paper argues that Moore’s principle of organic unities is false. Advocates of the principle have failed to take note of the distinction between actual intrinsic value and virtual intrinsic value. Purported cases of organic unities, where the actual intrinsic value of a part of a whole is allegedly defeated by the actual intrinsic value of the whole itself, are more plausibly seen as cases where the part in question has no actual intrinsic value but instead a plurality of merely (...) virtual intrinsic values.

Many writers accept the following thesis about responsibility: (R) For one to be responsible for something is for one to be such that it is fitting that one be the object of some reactive attitude with respect to that thing. This thesis bears a striking resemblance to a thesis about value that is also accepted by many writers: (V) For something to be good (or neutral, or bad) is for it to be such that it is fitting that it be (...) the object of some pro-attitude (or indifference, or some contra-attitude). V has been the subject of intense debate in recent years, in part because of its incorporation into what has come to be called the “buck-passing” account of value. In particular, V is open to three challenges: that it is not necessarily the case that whatever is good is the fitting object of a pro-attitude; that it is not necessarily the case that whatever is the fitting object of a pro-attitude is good; and that, even if there is a strict equivalence between what is good and what is the fitting object of a pro-attitude, still the former is not to be analyzed in terms of the latter. The resemblance between V and R has not been previously commented on, but, once it is recognized, it is clear that R is open to challenges that resemble those to which V is vulnerable. This paper explores both the challenges to V and the parallel challenges to R and discusses responses that may be given to these challenges. The interrelation between V and R is then examined, and a general lesson is drawn concerning how to adjudicate disputes about the nature of moral responsibility. (shrink)

This article argues that the dynamics behind the generation of social pathologies in modern society also undermine the social-relational framework for recognition. It therefore claims that the theory of recognition is impotent in face of the kinds of normative power exerted by social hierarchies. The article begins by discussing the particular forms of social pathology and their relation to hierarchical forms of social structure that are based on domination, control and subordination and then shows how the internalization of the norms (...) that shape and hold together hierarchical social formations causes pathologies within the self. As a result of these processes, the recognitive aspects of social action that the theory of recognition posits are unable to overcome and in fact reproduce and in many instances reinforce the pathologies themselves.

The ancient question of what a good life consists in is currently the focus of intense debate. There are two aspects to this debate: the first concerns how the concept of a good life is to be understood; the second concerns what kinds of life fall within the extension of this concept. In this paper, I will attend only to the first, conceptual aspect and not to the second, substantive aspect. More precisely, I will address the preliminary, underlying question of (...) how to understand what it is in general for something to be good for someone, from which an understanding of the more particular concept of a good life may be derived.

It is not very surprising that it was no less true in antiquity than it is today that adult human beings are held to be responsible for most of their actions. Indeed, virtually all cultures in all historical periods seem to have had some conception of human agency which, in the absence of certain responsibility-defeating conditions, entails such responsibility. Few philosophers have had the temerity to maintain that this entailment is trivial because such responsibility-defeating conditions are always present. Another not (...) very surprising fact is that ancient thinkers tended to ascribe integrality to "what is" (to on). That is, they typically regarded "what is" as a cosmos or whole with distinguishable parts that fit together in some coherent or cohesive manner, rather than either as a "unity" with no parts or as a collection containing members (ta onta or "things that are") standing in no "natural" relations to one another. 1 The philoso phical problem of determinism and responsibility may, I think, best be characterized as follows: it is the problem of preserving the phenomenon of human agency (which would seem to require a certain separateness of individual human beings from the rest of the cosmos) when one sets about the philosophical or scientific task of explaining the integrality of "what is" by means of the development of a theory of causation or explanation ( concepts that came to be lumped together by the Greeks under the term "aitia").

High quality learning is extensive, well integrated, deep, and supports the use of knowledge in new situations that require adaptation of what has been learned previously. This book reviews current research on the nature of high quality learning and the factors that facilitate or inhibit it. The book addresses relationships between quality of learning and learners' dispositions, teaching methods, cognitive strategies, assessment and technologies that can support learning. The chapters provide theoretical analyses, reports of classroom research, and suggestions for practical (...) application for both teachers and learners. The book will be of value to teachers at all levels of education and provides guidance for students about how to approach classroom tasks in order to develop high quality learning. (shrink)

In a recent article in this journal, I argued against the popular twofold Strawsonian claim that there can be no moral responsibility without a moral community and that, as a result, moral responsibility is essentially interpersonal. Benjamin De Mesel has offered a number of objections to my argument, including in particular the objection that I mischaracterized Strawson’s view. In this article, I respond to De Mesel’s criticisms.

In Ignorance of Law, Douglas Husak’s main thesis is that ignorance of the law typically provides an excuse for breaking the law, but in the case of recklessness he claims that the excuse it provides is only a partial one, and in the case of willful ignorance he claims that it provides no excuse at all. In this paper I argue that, given the general principle to which Husak appeals in order to support his main thesis, he should revise his (...) position on the exculpatory significance of both recklessness and willful ignorance.

The main point of this paper has been to show that the concept of evaluative incompleteness deserves consideration. In addition, I have suggested that it is plausible to accept that certain states of affairs in fact are evaluatively incomplete. But I have not sought to prove that this is so; indeed, I do not know how such proof might be given. Just which states of affairs, if any, are evaluatively incomplete is an extremely vexed question, and it is not one (...) to which I have attempted to supply any systematic answer. My aim has been merely to point out that it is arguable that certain states of affairs are evaluatively incomplete — a fact that ought not to be overlooked due to an unquestioning acceptance of (II) and a fact which, certainly, ought not to be ruled out by fiat due to an adherence to definitions and assumptions which imply that (II) is false.

For nearly two centuries, developmental biologists have known that body organs are derived from distinct germ layers. They have argued that adult stem cells formed in one of these, mesoderm for example, cannot give rise to cells that originate in another. We disagree. An exception to this “rule” has been described in crayfish recently. In this species, hemocytes appear to replenish neurogenic cells. This may happen in humans as well. In women who were given male bone marrow‐derived cells, Y chromosome (...) positive cheek cells and brain neurons were detected. While repopulation of these tissues by bone marrow derived cells may not occur normally, and while it does not appear to be terribly efficient, the phenomenon should be studied in more detail. Perhaps cells in the marrow could be used to regenerate tissues elsewhere. (shrink)

A combination of cytogenetic and molecular analyses has shown that several different transposable elements are involved in the restructuring of Drosophila chromosomes. Two kinds of elements, P and hobo, are especially prone to induce chromosome rearrangements. The mechanistic details of this process are unclear, but, at least some of the time, it seems to involve ectopic recombination between elements inserted at different chromosomal sites; the available data suggest that these ectopic recombination events are much more likely to occure between elements (...) in the same chromosome than between elements in different chromosomes. Other Drosophila transposons also appear to mediate chromosome restructuring by ectopic recombination; these include the retrotransposons BEL, roo, Docand I and the foldback element FB. In addition, two retrotransposons, HeT‐A and TART, have been found to be associated specifically with the ends of Drosophila chromosomes. Very limited data indicate that transposon‐mediated chromosome restructuring is occurring in natural populations of Drosophila. This suggests that transposable elements may help to shape the structure of the Drosophila genome and implies that they may have a similar role in other organisms. (shrink)

Advances in science are the combined result of the efforts of a great many scientists, and in many cases, their willingness to share the products of their research. These products include data sets, both small and large, and unique research resources not commercially available, such as cell lines and software programs. The sharing of these resources enhances both the scope and the depth of research, while making more efficient use of time and money. However, sharing is not without costs, many (...) of which are borne by the individual who develops the research resource. Sharing, for example, reduces the uniqueness of the resources available to a scientist, potentially influencing the originator’s perceived productivity and ultimately his or her competitiveness for jobs, promotions, and grants. Nevertheless, for most researchers—particularly those using public funds—sharing is no longer optional but must be considered an obligation to science, the funding agency, and ultimately society at large. Most funding agencies, journals, and professional societies now require a researcher who has published work involving a unique resource to make that resource available to other investigators. Changes could be implemented to mitigate some of the costs. The creator of the resource could explore the possibility of collaborating with those who request it. In addition, institutions that employ and fund researchers could change their policies and practices to make sharing a more attractive and viable option. For example, when evaluating an individual’s productivity, institutions could provide credit for the impact a researcher has had on their field through the provision of their unique resources to other investigators, regardless of whether that impact is reflected in the researcher’s list of publications. In addition, increased funding for the development and maintenance of user-friendly public repositories for data and research resources would also help to reduce barriers to sharing by minimizing the time, effort, and funding needed by individual investigators to comply with requests for their unique resource. Indeed, sharing is an imperative, but it is also essential to find ways to protect for both the original owner of the resource and those wishing to share it. (shrink)

The bacterium Deinococcus (formerly Micrococcus) radiodurans and other members of the eubacterial family Deinococaceae are extremely resistant to ionizing radiation and many other agents that damage DNA. Stationary phase D. radiodurans exposed to 1.0‐1.5 Mrad γ‐irradiation sustains >120 DNA double‐strand breaks (dsbs) per chromosome; these dsbs are mended over a period of hours with 100% survival and virtually no mutagenesis. This contrasts with nearly all other organisms in which just a few ionizing radiation induced‐dsbs per chromosome are lethal. In this (...) article we present an hypothesis that resistance of D. radiodurans to ionizing radiation and its ability to mend radiation‐induced dsbs are due to a special form of redundancy wherein chromosomes exist in pairs, linked to each other by thousands of four‐stranded (Holliday) junctions. Thus, a dsb is not a lethal event because the identical undamaged duplex is nearby, providing an accurate repair template. As addressed in this article, much of what is known about D. radiodurans suggests that it is particularly suited for this proposed novel form of DNA repair. (shrink)

It has recently been argued that the principle that "ought" implies "can" entails the principle that moral responsibility requires alternate possibilities, and hence that the acceptance of the former principle requires acceptance of the latter. This paper disputes the alleged entailment and gives reasons for accepting the former principle while rejecting the latter.

We use formal semantic analysis based on new constructions to study abstract realizability, introduced by Läuchli in 1970, and expose its algebraic content. We claim realizability so conceived generates semantics-based intuitive confidence that the Heyting Calculus is an appropriate system of deduction for constructive reasoning.Well-known semantic formalisms have been defined by Kripke and Beth, but these have no formal concepts corresponding to constructions, and shed little intuitive light on the meanings of formulae. In particular, the completeness proofs for these semantics (...) do not generate confidence in the sufficiency of the Heyting Calculus, since we have no reason to believe that every intuitively constructive truth is valid in the formal semantics.Läuchli has proved completeness for a realizability semantics with formal concepts analogous to constructions. We argue in some detail that, in spite of a certain inherent inexactness of the analogy, every intuitively constructive truth is valid in Läuchli semantics, and therefore the Heyting Calculus is powerful enough to prove all constructive truths. Our argument is based on the postulate that a uniformly constructible object must be communicable in spite of imprecision in our language, and that the permutations in Läuchli's semantics represent conceivable imprecision in a language, while allowing a certain amount of freedom in choosing the particular structure of the language.We give a detailed generalization of Läuchli's proof of completeness for the propositional part of the Heyting Calculus, in order to make explicit constructive and algebraic content.In our treatment, we establish several new results about Läuchli models. We show how to extend the sconing and gluing constructions familiar from Kripke and Frame semantics and Topos theory, to Läuchli models, and use them to give an algebraic approach to countermodel construction. In particular, the Läuchli arguments are given without the restriction to the integers, Z, as a group of permutations, which makes much of the coding scheme used in Läuchli's original paper transparent.We also make use of a new propositions-as-types syntax for the Heyting calculus, with limited nondeterminism, in which validity of formulae can be decided without loop-detection.

It is widely recognized that motivation is an important determinant for a successful sports career. Specific patterns of motivational constructs have recently demonstrated promising associations with future success in team sports like football and ice hockey. The present study scrutinizes whether those patterns also exist in individual sports and whether they are able to predict future performance levels. A sample of 155 young individual athletes completed questionnaires assessing achievement goal orientations, achievement motives, and self-determination at t1. The person-oriented method linking (...) of clusters after removal of a residue was used to form clusters based on these motivational constructs in order to analyze the relations between these clusters and the performance level 2.5 years later. Similar to the studies in team sports, four motivational patterns were observed at t1. The highly intrinsically achievement-oriented athletes were much more likely to compete internationally [odds ratio = 2.12], compared to the failure-fearing athletes. Although team and individual sports differ in many respects, they nevertheless are characterized by similar and thus generalizable career-promoting motivational profiles: Regardless of the type of sport, the highly intrinsically achievement-oriented athletes consistently have the best potential for success.

Frankfurt has attacked the principle that a person is morally responsible for what he has done only if he could have done otherwise, And he has thereby sought to undermine the traditional debate between compatibilists and incompatibilists. The role that the principle plays in this debate is clarified. Frankfurt's type of argument is then assessed for its implications concerning both the principle and the debate. It is argued that the debate, Even if not the principle, May well emerge intact.

Many philosophers have endorsed G. E. Moore’s principle of organic unities – according to which the value of a whole must not be assumed to be the same as the sum of the values of its parts – claiming this principle to be of fundamental importance to ethics. In this paper, I cast doubt on the principle. In Section 1, I provide a provisional reformulation of the principle of organic unities and contrast such unities with mere sums of value. In (...) Section 2, I do some groundwork in order to arrive at an account of the part–whole relation with which the principle of organic unities is concerned. In so doing, I provide some further reformulations of that principle. In Section 3, I discuss the isolation method that Moore proposes for determining the value of something, and then, in Section 4, I begin an extended discussion of a particular example of an alleged organic unity, namely, Schadenfreude. I explain why some philosophers claim that such pleasure constitutes an organic unity, but I also present reasons for denying this claim. In Section 5, I pursue one of these reasons in particular, a reason that appeals to the concept of what I call evaluative inadequacy, and, in Section 6, I seek to motivate this appeal by drawing on the relation between value and fitting attitudes. In so doing, I provide still further reformulations of the principle of organic unities. In Section 7, I entertain objections to my account of Schadenfreude, one of which requires one final reformulation of the principle of organic unities, and then, in Section 8, I discuss the more general objection that, even if my reasons for denying that Schadenfreude constitutes an organic unity are cogent, these reasons do not extend to other alleged organic unities, such as the related phenomenon of Mitleid. In the final section, I address the significance of the debate about whether the principle of organic unities is true. (shrink)

Argues that although the phenomenon of negative recency in secondary memory is usually attributed to the reduced amount of rehearsal associated with recency items, this phenomenon can be explained by the adoption of a different type of processing for recency items. An experiment with 122 undergraduates is reported in which the recall of recency items was reduced in an immediate test, but increased in a subsequent test, under conditions in which the recency items could not be identified as such during (...) their presentation. Results support the conclusion that the mode of processing items for an immediate free-recall test is normally modified for recency items. ((c) 1997 APA/PsycINFO, all rights reserved). (shrink)
