_Heidegger_ is a classic introduction to Heidegger's notoriously difficult work. Truly accessible, it combines clarity of exposition with an authoritative handling of the subject-matter. Richard Polt has written a work that will become the standard text for students looking to understand one of the century's greatest minds.

This treatise presents thoughts on the divide that exists in chemistry between those who seek their understanding within a universe wherein the laws of physics apply and those who prefer alternative universes wherein the laws are suspended or ‘bent’ to suit preconceived ideas. The former approach is embodied in the quantum theory of atoms in molecules (QTAIM), a theory based upon the properties of a system’s observable distribution of charge. Science is experimental observation followed by appeal to theory that, upon (...) occasion, leads to new experiments. This is the path that led to the development of the molecular structure hypothesis—that a molecule is a collection atoms with characteristic properties linked by a network of bonds that impart a structure—a concept forged in the crucible of nineteenth century experimental chemistry. One hundred and fifty years of experimental chemistry underlie the realization that the properties of some total system are the sum of its atomic contributions. The concept of a functional group, consisting of a single atom or a linked set of atoms, with characteristic additive properties forms the cornerstone of chemical thinking of both molecules and crystals and Dalton’s atomic hypothesis has emerged as the operational theory of chemistry. We recognize the presence of a functional group in a given system and predict its effect upon the static, reactive and spectroscopic properties of the system in terms of the characteristic properties assigned to that group. QTAM gives physical substance to the concept of a functional group. (shrink)

Although some attention has been devoted to assessing the attitudes and concerns of businesspeople toward ethics, relatively little attention has focused on the attitudes and concerns of tomorrow's business leaders, today's college students. In this investigation a national sample was utilized to study college students' attitudes toward business ethics, with the results being analyzed by academic classification, academic major, and sex. Results of the investigation indicate that college students are currently somewhat concerned about business ethics in general, and that female (...) students in particular are more concerned about ethical issues than are their male counterparts.

The increased usage of marketing communications on the internet has presented a number of significant business ethics issues. And, while regulatory agencies have increased their vigilance in protecting consumers from injury, the uniqueness of business via the internet has challenged these agencies to respond in evolving ways. This paper provides a brief overview of the application of the FTC''s lesser known unfairness doctrine as a potential framework for better understanding emerging privacy and e-commerce issues, and specific examples are provided for (...) illustration.

BackgroundPreprint usage is growing rapidly in the life sciences; however, questions remain on the relative quality of preprints when compared to published articles. An objective dimension of quality that is readily measurable is completeness of reporting, as transparency can improve the reader’s ability to independently interpret data and reproduce findings.MethodsIn this observational study, we initially compared independent samples of articles published in bioRxiv and in PubMed-indexed journals in 2016 using a quality of reporting questionnaire. After that, we performed paired comparisons (...) between preprints from bioRxiv to their own peer-reviewed versions in journals.ResultsPeer-reviewed articles had, on average, higher quality of reporting than preprints, although the difference was small, with absolute differences of 5.0% [95% CI 1.4, 8.6] and 4.7% [95% CI 2.4, 7.0] of reported items in the independent samples and paired sample comparison, respectively. There were larger differences favoring peer-reviewed articles in subjective ratings of how clearly titles and abstracts presented the main findings and how easy it was to locate relevant reporting information. Changes in reporting from preprints to peer-reviewed versions did not correlate with the impact factor of the publication venue or with the time lag from bioRxiv to journal publication.ConclusionsOur results suggest that, on average, publication in a peer-reviewed journal is associated with improvement in quality of reporting. They also show that quality of reporting in preprints in the life sciences is within a similar range as that of peer-reviewed articles, albeit slightly lower on average, supporting the idea that preprints should be considered valid scientific contributions.

American taxpayers spend $30 billion annually funding biomedical research. By some estimates, half of the results from these studies can't be replicated elsewhere-the science is simply wrong. Often, research institutes and academia emphasize publishing results over getting the right answers, incentivizing poor experimental design, improper methods, and sloppy statistics. Bad science doesn't just hold back medical progress, it can sign the equivalent of a death sentence. How are those with breast cancer helped when the cell on which 900 papers are (...) based turns out not to be a breast cancer cell at all? How effective could a new treatment for ALS be when it failed to cure even the mice it was initially tested on? In Rigor Mortis, award-winning science journalist Richard F. Harris reveals these urgent issues with vivid anecdotes, personal stories, and interviews with the nation's top biomedical researchers. We need to fix our dysfunctional biomedical system-now.

Richard Polt takes a fresh approach to Heidegger’s thought during his most politicized period, and works toward a philosophical appropriation of his most valuable ideas. Polt shows how central themes of the 1930s—such as inception, emergency, and the question “Who are we?”—grow from seeds planted in Being and Time and are woven into Heidegger’s political thought. Working with recently published texts, including Heidegger’s Black Notebooks, Polt traces the thinker’s engagement and disengagement from the Nazi movement. He critiques Heidegger for (...) his failure to understand the political realm, but also draws on his ideas to propose a “traumatic ontology” that understands individual and collective existence as identities that are always in question, and always remain exposed to disruptive events. Time and Trauma is a bold attempt to gain philosophical insight from the most problematic and controversial phase of Heidegger’s thought. (shrink)

The cerebellum has been hypothesized to play a role in a variety of movement timing tasks that involve the processing of temporal information on a variety of timescales. Braitenberg, Heck & Sultan propose a new theory of cerebellar function that is able to account for movement timing on the order of a couple of hundred milliseconds. However, this theory does not account for the rôle the cerebellum plays in the acquisition and retention of adaptively timed discrete movements that are on (...) the order of 200 to 1000 milliseconds, and therefore does not account for the entire temporal range of cerebellar dependent processing.

Piaget's social psychology is not widely discussed among psychologists, partly because much of it is still contained in untranslated French works. In this article I summarize the main lines of Piaget's social psychology and briefly indicate its relation to current theories in social psychology. Rejecting both Durkheim's sociological holism and Tarde's individualism, Piaget advances a sociological relativism in which all social facts are reducible to social relations and these, in turn, are reducible to rules, values and signs. Piaget's theory of (...) social values takes the form of a social exchange theory characterized in an abstract logical way. Piaget claims social exchange requires normative principles of reciprocity and that individual social development results in such an equilibrium because rationality itself is social and based upon social cooperation. These views, in turn, derive from Piaget's orthogenetic views concerning the course of evolution: development can be characterized as an increase in equilibrium manifested both in individual action and in social interaction.

Genetic epistemology analyzes the growth of knowledge both in the individual person (genetic psychology) and in the socio-historical realm (the history of science). But what the relationship is between the history of science and genetic psychology remains unclear. The biogenetic law that ontogeny recapitulates phylogeny is inadequate as a characterization of the relation. A critical examination of Piaget's Introduction à l'Épistémologie Généntique indicates these are several examples of what I call stage laws common to both areas. Furthermore, there is at (...) least one example of a paradoxical inverse relation between the two — geometry. Both similarities and differences between the two domains require an explanation, a developmental explanation. Although such an explanation seems to be psychological in nature, it is not merely empirical but also normative (since psychology is both factual and normative according to Piaget). Hence genetic epistemology need not be reduced to psychology (narrowly conceived), but rather should be seen as being both empirical and normative and thus similar to certain types of contemporary philosophy of science.

This book describes Descartes's The Passions of the Soul as a foundational work of the Enlightenment, a precursor of later notions of the historicity of the human, and the first psychology of modern type: to understand and heal ourselves, we look not outward at the world in immediate relation to it, but inward, at the self, its brain, and its past history. Special attention is given to Descartes’s account of imagination and its problematic impact on passion and volition.

Several philosophers have questioned the possibility of a genetic epistemology, an epistemology concerned with the developmental transitions between successive states of knowledge in the individual person. Since most arguments against the possibility of a genetic epistemology crucially depend upon a sharp distinction between the genesis of an idea and its justification, I argue that current philosophy of science raises serious questions about the universal validity of this distinction. Then I discuss several senses of the genetic fallacy, indicating which sense of (...) ‘genesis’ is relevant to epistemology. Next I consider the objection that psychology is irrelevant to epistemology, and that since "genetic epistemology" is really psychology, "genetic epistemology" is irrelevant to a real epistemology. Finally, I take up the objection that nothing discovered in genetic psychology could be relevant to a genetic epistemology. These last two arguments are based upon what I claim to be a mistaken notion of the nature of psychology. Suitably interpreted, psychology can assist genetic epistemology precisely in the way that the history of science assists current philosonhv of science. *I owe considerable thanks to Jann Benson, Ken Freeman, Bernie Rollin and Ron Williams for their helpful discussions concerning many of the issues discussed in this paper. I also wish to thank David Hamlyn, John Heil, William Lycan, Harvey Siegel and an anonymous reviewer for their comments and suggestions. It goes without saying that none of these individuals (especially Hamlyn and Siegel) necessarily agree with me. An earlier version of this paper was read at Colorado State University where the audience's comments were beneficial. (shrink)

Although the theory of Jean Piaget is correctly characterized as genetic epistemology, its nature and scope remain unclear and controversial. An examination of Piaget's Introduction a l'epistemologie genetique indicates that Piaget relies heavily upon a model of comparative anatomy and, consequently, that genetic epistemology is about both the history of science and individual development. This biological model seems to be the basis for Piaget's view that the history of science can be seen as a (Kantian) history of scientific concepts whereas (...) psychogenetic development is a history of these very same concepts on the individual level. Finally, although there are passages indicating a different interpretation of the scope of genetic epistemology, I give several reasons for preferring the more liberal interpretation. (shrink)

Heidegger's Being and Time: Critical Essays provides a variety of recent studies of Heidegger's most important work. Twelve prominent scholars, representing diverse nationalities, generations, and interpretive approaches deal with general methodological and ontological questions, particular issues in Heidegger's text, and the relation between Being and Time and Heidegger's later thought. All of the essays presented in this volume were never before available in an English-language anthology. Two of the essays have never before been published in any language ; three of (...) the essays have never been published in English before, and two of the essays provide previews of works in progress by major scholars.

The existence of free will has been both an enduring presumption of Western culture and a subject for debate across disciplines for millennia. However, little empirical evidence exists to support the almost unquestioned assumption that, in general, Westerners endorse the existence of free will. The few studies that measure belief in free will have methodological problems that likely resulted in underestimating the true extent of belief. Recently, Rakos et al. (Behavior and Social Issues 17:20–39, 2008 ) found a stronger endorsement (...) of free will when demand characteristics were eliminated. The current study builds on this work by sampling incarcerated adolescents and adults, whose freedom to act is externally constrained. Belief in free will as well as attitudes toward punishment, self-esteem, and locus of control were measured. The results indicate that free will is strongly endorsed in Western society even when freedom to act is severely restricted. However, incarcerated adolescents endorsed free will to a slightly lesser extent than their nonincarcerated counterparts from Rakos et al. (Behavior and Social Issues 17:20–39, 2008 ), while incarcerated and nonincarcerated adults offered equally strong endorsements. The comparable endorsement by adults is consistent with the hypothesis that the belief in agency is an evolutionary adaptation. The small decrease found for incarcerated adolescents may reflect the interaction between developmental factors and the expression of an evolutionary adaptation. Additionally, incarcerated adolescents and adults associated beliefs in free will with viewing punishment as a means of deterrence, rehabilitation, and retribution. Incarcerated adults, but not incarcerated adolescents, associated beliefs in free will with greater self-esteem and with an external locus of control. Finally, though both incarcerated adults and adolescents endorsed free will strongly, the former manifested the belief by emphasizing free agentic choice whereas the latter focused on the personal responsibility that is interwoven with free choice. The implications of these findings are discussed in the context of evolutionary, cultural, and developmental factors. (shrink)

Although numerous aspects of Bertrand Russell's philosophical views have been discussed, his views about the nature of the mind and the place of psychology within modern science have received less attention. In particular, there has been little discussion of what I will call "Russell's flirtation with behaviorism." Although some individuals have mentioned this phase in Russell's philosophical career, they have not adequately situated it within Russell's changing philosophical views, in particular, his naturalistic epistemology. I briefly discuss this naturalistic epistemology and (...) the kind of behaviorism it resulted in. I also briefly compare it to the behaviorism of John Watson, which had a strong influence on Russell. Russell finally abandoned this extreme form of behaviorism because of its denial of mental images, which was crucial to Russell's philosophy of mind and his semantics. I suggest that even though Russell's flirtation with behaviorism came to an end, he continued to be committed to a naturalistic epistemology. If this is so, we need to reassess the views of Russell and their place in twentieth-century thought. (shrink)

This book assesses how Vatican II opened up the Catholic Church to encounter, dialogue, and engagement with other world religions. Opening with a contribution from the President of the Pontifical Council for Interreligious Dialogue, Cardinal Jean-Louis Tauran, it next explores the impact, relevance, and promise of the Declaration Nostra Aetate before turning to consider how Vatican II in general has influenced interfaith dialogue and the intellectual and comparative study of world religions in the postconciliar decades, as well as the contribution (...) of particular past and present thinkers to the formation of current interreligious and comparative theological methods. Additionally, chapters consider interreligious dialogue vis-à-vis theological anthropology in conciliar documents; openness to the spiritual practices of other faith traditions as a way of encouraging positive interreligious encounter; the role of lay and new ecclesial movements in interreligious dialogue; and the development of Monastic Interreligious Dialogue. Finally, it includes a range of perspectives on the fruits and future of Vatican’s II’s opening to particular faiths such as Judaism, Islam, Hinduism, and Buddhism. (shrink)

Bertrand Russell is widely considered to be one of the founders of analytic philosophy, epistemology, and philosophy of science. Individuals have usually stressed his early philosophical contributions as seminal in this regards. But Russell also had another side–a naturalistic side–leading him towards a naturalistic epistemology and naturalistic philosophy of science of the type Quine later made famous. My goal is to provide an outline of Russell's naturalistic epistemology and the underlying philosophical motivations for such a move. After briefly presenting Russell's (...) conception of the nature of philosophy, I sketch his theory of philosophical method, which is a version of the method of analysis. This provides the underpinnings for a discussion of his Naturalistic Epistemology, which led him to adopt a version of a behavioristic epistemology. Although Russell vacillated on the question of the adequacy of such an account, it provided a major element in his later philosophical views. I suggest that we must reevaluate our conception of the history of analytic philosophy and, in particular, our understanding of Russell's place in the history of 20th century philosophy. (shrink)

This 1984 book describes the development of thought, both of Keynes and others, culminating in the publication in 1936 of Keynes' General Theory of Employment, Interest and Money. As one of Keynes' close collaborators - from December 1929, when the writing of the Treatise was nearing its completion - Richard Khan provides a uniquely insightful analysis of these events. The author starts with a brief survey of the contributions influential in forming Keynes' early ideas, and moves on to explore (...) the significance of the Quantity Theory of Money, and traces the development of Keynes' attitude towards the theory through his published books. Subsequent lectures are devoted to Keynes' Treatise on Money, and to his more popular writings as an economic adviser which marked the transition from the thinking in the Treatise to that in the General Theory which the author critically examines. The final lecture records the author's memory of his personal relationship with Keynes. (shrink)

I shall develop the suggestion that the thing in itself is not in any sense a thing. Nor is it a term which refers to a reality in opposition to which objects of experience are unfavorably compared. Yet Kant uses language which sometimes suggests both, providing ground for Schrader's observation about both the obscurity and the perversity of the doctrine.

Aristotelian, classical, and quantum physics are compared and contrasted in light of Jacob Klein’s account of the algebraicization of thought and the resultingdetachment of mind from world, even as human problem-solving power is greatly increased. Two fundamental features of classical physics are brought out: species-neutrality, which concerns the relation between the intelligible and the sensible, and physico-mathematical secularism, which concerns the question of the difference between mathematical objects and physical objects, and whether any differences matter. In contrast to Aristotelian physics, (...) which is species-specific, classical physics is species-neutral. In contrast to both Aristotelian and quantum physics, classical physics assumes that any differences between mathematical objects and physical objects make no difference for the conduct of physics. Aristotle’s act and potency, and Heisenberg’s uncertainty principle are discussed as counterexamples to the physico-mathematical secularism of classical physics. The algebraicization of thought in conjunction with the disposition and program for the mastery of nature leads to the homogenization of heterogeneities in both mathematics and physics, and, therewith, to confusion concerning the meaning of human being and our place in the whole.

In the Critique of Pure Reason Kant attempts to solve two problems about our knowledge of the world. First, how can we know any necessary truths about the world, such as the principle that every event must have a cause? Second, how can I know that things other than I exist at all? Kant’s strategy for dealing with both these problems is to repudiate the kind of distinction that Descartes and Hume had made between self-knowledge and our knowledge of ‘outer’ (...) things. Kant’s innovation is to distinguish sharply between two sides of what his predecessors understood as self-knowledge: ‘inner sense’ and ‘apperception.’ This paper shows how Kant's conception of ‘apperception’ is meant to overcome Humean skepticism, and how ‘inner sense’ is meant to overcome Cartesian skepticism; I then touch upon a complication in Kant’s view of the relation between apperception and inner sense, a complication which relates directly to the problem of the ‘thing in itself.’.

What is the role of Leibniz’s early work in the constitution of his mature philosophy? Conventional scholarship would emphasize 1686 as the point at which the Leibnizian philosophical system was in place, subsequent obscurities concerning forces and monads notwithstanding. In that year the Discourse on Metaphysics was completed, the Brief Demonstration of Leibniz’s discovery of the conservation of living force was published, and the correspondence with Arnauld begun, leading to the 1695 publication of the New System and part I of (...) its companion Specimen Dynamicum. On this forward-looking account, the early period recedes in importance. Against this rough but established consensus, Christia Mercer argues that far more weight needs to be given to Leibniz’s early development—especially the period from 1668 to 1672—in the Aristotelian and Platonic eclecticism of seventeenth-century Germany. Daniel Garber’s advertisement on the book jacket pertains: “Though it will be controversial, her position is one that must be reckoned with.... [I]t will be read and passionately debated for years to come.”. (shrink)

The still astonishing expansion of the American university since World War II has transformed the nation's intellectual and cultural life in myriad ways. Most intellectual historians familiar with this period would agree, I suppose, that among the conspicuous changes is the sheer increase in the size and diversity of intellectual and cultural activity taking place on campuses across the country. After all, we know that colleges and universities that employ us also provide full- and part-time academic appointments to novelists, poets, (...) playwrights, filmmakers, choreographers, composers, classical and jazz musicians, painters, photographers, and sculptors, even though most of them probably began their careers with little or no desire to join us in the halls of academe. This now widespread employment practice has decentralized the nation's literary and artistic talent. It also has made for a manifold increase in degree-granting programs in writing and the creative arts. One example will suffice here. When World War II ended, there were a small handful of university-based creative-writing programs. Over the course of the next thirty years, the number increased to fifty-two. By 1985, there were some 150 graduate degree programs offering an MA, MFA, or PhD. As of 2004, there were more than 350 creative-writing programs in the United States, all staffed by practicing writers and poets, many of whom now also hold advanced degrees in creative writing.

Among other things, R. O. A. M. Lyne's recent edition and commentary of the Ciris has established the general method of composition followed by this pseudo-neoteric poet: he demonstrably lifted wholesale and applied to his own poem words, phrases, lines, and even entire sequences from the works of the neoterics and the poets of the following generation. Accordingly, one of the poem's chief attributes is that it serves as a means for recovering the general content, and at times the actual (...) wording, of earlier, more important poetry. This paper offers some additional areas in the Ciris where such influence may exist. I confine myself to Cinna and Calvus, whose poetry may justly be considered the missing two-thirds of the neoteric movement. (shrink)

Natural myside bias is the tendency to evaluate propositions from within one's own perspective when given no instructions or cues (such as within-participants conditions) to avoid doing so. We defined the participant's perspective as their previously existing status on four variables: their sex, whether they smoked, their alcohol consumption, and the strength of their religious beliefs. Participants then evaluated a contentious but ultimately factual proposition relevant to each of these demographic factors. Myside bias is defined between-participants as the mean difference (...) in the evaluation of the proposition between groups with differing prior status on the variable. Whether an individual difference variable (such as cognitive ability) is related to the magnitude of the myside bias is indicated by whether the individual difference variable interacts with the between-participants status variable. In two experiments involving a total of over 1400 university students ( n = 1484) and eight different comparisons, we found very little evidence that participants of higher cognitive ability displayed less natural myside bias. The degree of myside bias was also relatively independent of individual differences in thinking dispositions. We speculate that ideas from memetic theory and dual-process theory might help to explain why natural myside bias is quite dissociated from individual difference variables. (shrink)

Individual differences on a variety of framing and conjunction problems were examined in light of Slovic and Tversky's (1974) understanding/acceptance principle-that more reflective and skilled reasoners are more likely to affirm the axioms that define normative reasoning and to endorse the task construals of informed experts. The predictions derived from the principle were confirmed for the much discussed framing effect in the Disease Problem and for the conjunction fallacy on the Linda Problem. Subjects of higher cognitive ability were disproportionately likely (...) to avoid each fallacy. Other framing problems produced much more modest levels of empirical support. It is conjectured that the varying patterns of individual differences are best explained by two-process theories of reasoning (e.g. Evans, 1984, 1996; Sloman, 1996) conjoined with the assumption that the two processes differentially reflect interactional and analytic intelligence.

We did not, as Brakel & Shevrin imply, intend to classify either System 1 or System 2 as rational or irrational. Instrumental rationality is assessed at the organismic level, not at the subpersonal level. Thus, neither System 1 nor System 2 are themselves inherently rational or irrational. Also, that genetic fitness and instrumental rationality are not to be equated was a major theme in our target article. We disagree with Bringsjord & Yang's point that the tasks used in the heuristics (...) and biases literature are easy. Bringsjord & Yang too readily conflate the ability to utilize a principle of rational choice with the disposition to do so. Thus, they undervalue tasks in the cognitive science literature that compellingly reveal difficulties with the latter. We agree with Newton & Roberts that models at the algorithmic level of analysis are crucial, but we disagree with their implication that attention to issues of rationality at the intentional level of analysis impedes work at the algorithmic level of analysis.
