Research has consistently revealed gender differences in attitudes toward science and technology. One explanation is that women are more personally affected by particular technologies, so they consider them differently. However, not all women universally experience biomedical technologies. We use the concept of technological salience to address how differences in subjective implications of a technology might explain differences in women’s attitudes toward biotechnology. In a sample of U.S. women from the National Survey of Fertility Barriers, we examine how women with and (...) without a biomedical barrier to fertility evaluate biotechnology for infertility, which, we argue, reflects differences in technological salience. For women with a biomedical barrier, various experiences, beliefs, and values impacted their attitudes; yet, most of these did not affect attitudes if women had not experienced a fertility barrier. Results suggest that technological salience contextualizes women’s attitudes toward these biotechnologies and may also have broader implications for other biotechnologies. (shrink)

Language’s intentional nature has been highlighted as a crucial feature distinguishing it from other communication systems. Specifically, language is often thought to depend on highly structured intentional action and mutual mindreading by a communicator and recipient. Whilst similar abilities in animals can shed light on the evolution of intentionality, they remain challenging to detect unambiguously. We revisit animal intentional communication and suggest that progress in identifying analogous capacities has been complicated by (i) the assumption that intentional (that is, voluntary) production (...) of communicative acts requires mental-state attribution, and (ii) variation in approaches investigating communication across sensory modalities. To move forward, we argue that a framework fusing research across modalities and species is required. We structure intentional communication into a series of requirements, each of which can be operationalised, investigated empirically, and must be met for purposive, intentionally communicative acts to be demonstrated. Our unified approach helps elucidate the distribution of animal intentional communication and subsequently serves to clarify what is meant by attributions of intentional communication in animals and humans.

In Neutrality and the Academic Ethic, distinguished philosopher Robert L. Simon explores the claim that universities can and should be politically neutral. He examines conceptual questions about the meaning of neutrality, distinguishes different conceptions of what neutrality involves, and considers in what sense, if any, institutional neutrality is both possible and desirable. In Part II, a collection of original and previously published essays provides different views on these and related issues.

According to Bayesian epistemology, rational learning from experience is consistent learning, that is learning should incorporate new information consistently into one's old system of beliefs. Simon M. Huttegger argues that this core idea can be transferred to situations where the learner's informational inputs are much more limited than Bayesianism assumes, thereby significantly expanding the reach of a Bayesian type of epistemology. What results from this is a unified account of probabilistic learning in the tradition of Richard Jeffrey's 'radical (...) probabilism'. Along the way, Huttegger addresses a number of debates in epistemology and the philosophy of science, including the status of prior probabilities, whether Bayes' rule is the only legitimate form of learning from experience, and whether rational agents can have sustained disagreements. His book will be of interest to students and scholars of epistemology, of game and decision theory, and of cognitive, economic, and computer sciences. (shrink)

Highly idealized models, such as the Hawk-Dove game, are pervasive in biological theorizing. We argue that the process and motivation that leads to the introduction of various idealizations into these models is not adequately captured by Michael Weisberg’s taxonomy of three kinds of idealization. Consequently, a fourth kind of idealization is required, which we call hypothetical pattern idealization. This kind of idealization is used to construct models that aim to be explanatory but do not aim to be explanations.

A dozen papers by internationally known scholars explore questions largely unthinkable without Richard Watson's classic Downfall of Cartesianism: Descartes in Holland, Descartes and Simon Foucher, and issues raised by Descartes for philosophy of mind, philosophy of science, translation and toleration.

One of the main contributions of Richard Bradley’s book is an elegant extension of Jeffrey’s Logic of Decision that countenances the evaluation of conditional prospects. This extension offers a promising new setting in which to model dynamic choice. In Bradley’s framework, plans can be understood as conditionals of an appropriate sort, while dynamic consistency can be viewed as providing a constraint on the evaluation of conditionals across time. In this paper, we study connections between planning conditionals and dynamic consistency.

Biological evolution provides a creative fount of complex and subtle adaptations, often surprising the scientists who discover them. However, because evolution is an algorithmic process that transcends the substrate in which it occurs, evolution’s creativity is not limited to nature. Indeed, many researchers in the field of digital evolution have observed their evolving algorithms and organisms subverting their intentions, exposing unrecognized bugs in their code, producing unexpected adaptations, or exhibiting outcomes uncannily convergent with ones in nature. Such stories routinely reveal (...) creativity by evolution in these digital worlds, but they rarely fit into the standard scientific narrative. Instead they are often treated as mere obstacles to be overcome, rather than results that warrant study in their own right. The stories themselves are traded among researchers through oral tradition, but that mode of information transmission is inefficient and prone to error and outright loss. Moreover, the fact that these stories tend to be shared only among practitioners means that many natural scientists do not realize how interesting and lifelike digital organisms are and how natural their evolution can be. To our knowledge, no collection of such anecdotes has been published before. This paper is the crowd-sourced product of researchers in the fields of artificial life and evolutionary computation who have provided first-hand accounts of such cases. It thus serves as a written, fact-checked collection of scientifically important and even entertaining stories. In doing so we also present here substantial evidence that the existence and importance of evolutionary surprises extends beyond the natural world, and may indeed be a universal property of all complex evolving systems.

At the forefront of international concerns about global legislation and regulation, a host of noted environmentalists and business ethicists examine ethical issues in consumption from the points of view of environmental sustainability, economic development, and free enterprise.

Peter Abelard (1079–1142 ce) was the most wide‐ranging philosopher of the twelfth century. He quickly established himself as a leading teacher of logic in and near Paris shortly after 1100. After his affair with Heloise, and his subsequent castration, Abelard became a monk, but he returned to teaching in the Paris schools until 1140, when his work was condemned by a Church Council at Sens. His logical writings were based around discussion of the “Old Logic”: Porphyry's Isagoge, aristotle'S Categories and (...) On Interpretation and boethius'S textbook on topical inference. They comprise a freestanding Dialectica (“Logic”; probably c.1116), a set of commentaries (known as the Logica [Ingredientibus], c. 1119) and a later (c. 1125) commentary on the Isagoge (Logica Nostrorum Petititoni Sociorum or Glossulae). In a work Abelard called his Theologia, issued in three main versions (between 1120 and c.1134), he attempted a logical analysis of trinitarian relations and explored the philosophical problems surrounding God's claims to omnipotence and omniscience. The Collationes (“Debates,” also known as “Dialogue between a Christian, a Philosopher and a Jew”; probably c.1130) present a rational investigation into the nature of the highest good, in which the Christian and the Philosopher (who seems to be modeled on a philosopher of pagan antiquity) are remarkably in agreement. The unfinished Scito teipsum (“Know thyself,” also known as the “Ethics”; c.1138) analyses moral action. (shrink)

In many animal species, the early development of the embryo follows a stereotypic pattern of cell cleavage, lineage allocation and generation of tissue asymmetry leading to delineation of the body plan with three primary embryonic axes. The mammalian embryo has been regarded as an exception and primary body axes of the mouse embryo were thought to develop after implantation. However, recent findings have challenged this view. Asymmetry in the fertilised oocyte, as defined by the position of the second polar body (...) and the sperm entry point, can be correlated with the orientation of the animal–vegetal and the embryonic–abembryonic axes in the preimplantation blastocyst. Studies of the pattern of morphogenetic movement of cells and genetic activity in the peri‐implantation embryo suggest that the animal–vegetal axis of the blastocyst might presage the orientation of the anterior–posterior axis of the gastrula. This suggests that the asymmetry of the zygote that is established at fertilisation and early cleavage has a lasting impact on the delineation of body axes during embryogenesis.

Pancreatitis is a complex, progressively destructive inflammatory disorder. Alcohol was long thought to be the primary causative agent, but genetic contributions have been of interest since the discovery that rare PRSS1, CFTR and SPINK1 variants were associated with pancreatitis risk. We now report two associations at genome-wide significance identified and replicated at PRSS1-PRSS2 and X-linked CLDN2 through a two-stage genome-wide study. The PRSS1 variant likely affects disease susceptibility by altering expression of the primary trypsinogen gene. The CLDN2 risk allele is (...) associated with atypical localization of claudin-2 in pancreatic acinar cells. The homozygous CLDN2 genotype confers the greatest risk, and its alleles interact with alcohol consumption to amplify risk. These results could partially explain the high frequency of alcohol-related pancreatitis in men. © 2012 Nature America, Inc. All rights reserved. (shrink)

A letter to The Times of London, May 9, 1992 protesting the Cambridge University proposal to award an honorary degree to M. Jacques Derrida.

Thomas More's History of Richard III is a metahistory, rich in factual and fictional details. I will discuss More's concept of historiography as a rhetorical art and how his presentation of history transformed details of what was imperfectly known about Richard III into a polemic about what should be believed as an irrefutable truth. More's conception of history is much more amorphous than modern theories. He incorporated classical myths, literature, history, and philosophy along with phantasies, dreams, and oral (...) testimonies to recreate his historical Richard III as a tragic figure. More saw patterns of immoral behavior deeply rooted in the histories of the Plantagenet kings from the twelfth century to 1485 as if the sins of the fathers are repeated by their children. More used his sources, the antiquarian John Rous, the historian Polydore Vergil, and the oral history of Archbishop/cardinal John Morton to prove that the immorality of the Plantagenets, embodied in Richard III, was a curse that will be purged from England by the ascendance of Henry VII. William Shakespeare copied and embellished More's tragic vision of Richard III. Their historical facts and fictions enhanced their moral signification of the rise and fall of Richard III in English history. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:The Breakdown of C i M phy " artes an eta sacs RICHARD A. WATSON WITHIN CARTESIANISMthere arose many problems deriving from conflicts between Cartesian principles. Inadequate attempts to solve these problems were crucial reasons for the breakdown of Cartesian metaphysics in the late seventeenth and early eighteenth centuries. The major difficulties derived from the acceptance of a dualism of substances seated in a system which included epistemological (...) and causal likeness principles plus an ontological framework in which the categories of substance and modification were exhaustive. The major solutions involved either denying the likeness principles or altering the ontological framework. The first led to unintelligibility ; the second, culminating in Hume, opened the way to non-Cartesian metaphysics. The first section of this study contains a characterization of late seventeenth -century Cartesian metaphysics. The second is an exposition of Foucher 's four major criticisms of this system. In the third section, monistic solutions suggested in Descartes and by Spinoza, Foucher, Leibniz, and Locke are considered; in the fourth, the dualistic solutions of the orthodox Cartesians Rohault, R~gis, Desgabets, La Forge, Le Grand, and Arnauld; and in the fifth, the occasionalist solution of Malebranche. The sixth section is an analysis of these orthodox and occasionalist solutions, showing how each ultimately fails because of dependence upon the ontology of substance and modification. The seventh section is a consideration of Berkeley and Hume in the Cartesian context. A consideration of their systems as offering solutions to Cartesian problems illuminates in new light both the systems and the problems. In broad terms, this study moves from a consideration of problems arising from an ontology of two substances, to a consideration of problems arising from the ontological pattern of substance and modification. The Cartesians were concerned with relationships between two substances, but they saw no difficulties connected with the relationship between a substance and its modifications (or properties). Berkeley's treatment (deriving from Male- [177] 178 HISTORY OF PHILOSOPHY branche) of the relationships between mind and idea, and between mind and notion, is illuminated by a consideration of the extent to which he took these relationships for granted in the Cartesian way, and of the extent to which he saw difficulties in the relationship between substance and modification. The Berkeleian solution to Cartesian problems, like that of Malebranche before him, was not successful; Malebranche belittled, and Berkeley denied the dualism of substances, but neither philosopher could break entirely with the ontological pattern of substance and modification. The final breakdown of Cartesian metaphysics came with Hume, who, in providing the culmination of a most important trend in modern philosophy, opened the way to new metaphysics and became the father of contemporary philosophy. I A model late seventeenth-century Cartesian metaphysical system. The last grand expositor of the Cartesian philosophy was Antoine Le Grand who in 1694 published An Entire Body of Philosophy. The characterization of the late seventeenth-century Cartesian system given below follows Le Grand's exposition more closely than others, but it also incorporates elements from those of Rohault, R6gis, Desgabets, La Forge, Malebranche, and Arnauld.1 None of these philosophers professed a system of exactly the sort this characterization pictures, nor is it implied here that they do. The guide and rationale for drawing from them such a model Cartesianism is the polemical writing of Simon Foucher. Foucher's series of attacks upon Cartesianism (of which the second is his criticism of Malebranche of 1675, Critique de la Rdcherche de la veritd) give clearly the most important objections against Cartesian metaphysics.2The system outlined below, while more com1Le Grand, Antoine, An Entire Body of Philosophy According to the Principles of the Famous Renate des Cartes (London, 1694); Rohault, Jacques, Traitd de physique (Paris, 1671); R6gis, Pierre-Sylvain, Syst~me de philosophie, contenant la logique, la mdtaphysique, la physique et la morale (Lyon, 1690); Desgabets, Robert, Critique de la Critique de la Recherche de la veritd, oCt l'on decouvre le chemin qui conduit aux connoissances solides.

The measurement of sensory intensity has had a long history, attracting the attention of investigators from many disciplines including physiology, psychology, physics, mathematics, philosophy, and even chemistry. While there has been a continuing doubt by some that sensation has the properties necessary for measurement, experiments designed to obtain estimates of sensory intensity have found that a general rule applies: Equal stimulus ratios produce equal sensory ratios. Theories concerning the basis for this simple psychophysical rule are discussed, with emphasis given to (...) the physical correlate theory, which considers judgments of subjective magnitudes to be based upon estimates of physical dimensions that vary regularly with changes in degree of stimulation. For the most thoroughly investigated sensory scales, brightness and loudness, the physical correlate is considered to be distance. Our “tacit knowledge” of the sensory effects of changing distance plays an essential role in matching motor activities to environmental conditions and in ensuring accurate perceptual evaluations through brightness and loudness constancies. In psychophysical experiments, subjects apparently use this same tacit knowledge when required to estimate relative subjective magnitudes. The evidence related to the physical correlate theory is summarized, and it is concluded that, while under appropriate conditions we demonstrate considerable skill in evaluating environmental relationships, we are quite unable to estimate the neurophysiological nature or quantity of sensory response. A psychophysics devoted to studying conditions required for accuracy and conditions producing errors in the perception of environmental relationships would seem to be more valuable than one devoted to subjective magnitudes.

Ethics and the Clinical Encounter explores the moral dimensions of clinical medicine and the phenomenon of illness, to determine what ethics must be in order to be fully responsive to clinical encounters.

Here's what the experts had to say: Professor Zaner has provided us with a remarkably (...) lucid and trenchant discussion of the interface of philosophy and the field of medicine. He brings into play an extraordinary range of historial knowledge, extensive observations based on firsthand experience with medical practices, and an acute sense of philosophical argumentation.

Tested the 2-process theory of detection, search, and attention presented by the current authors in a series of experiments. The studies demonstrate the qualitative difference between 2 modes of information processing: automatic detection and controlled search; trace the course of the learning of automatic detection, of categories, and of automatic-attention responses; and show the dependence of automatic detection on attending responses and demonstrate how such responses interrupt controlled processing and interfere with the focusing of attention. The learning of categories is (...) shown to improve controlled search performance. A general framework for human information processing is proposed. The framework emphasizes the roles of automatic and controlled processing. The theory is compared to and contrasted with extant models of search and attention. (shrink)

Consciousness, thus, takes on the characteristic of being "here and now" (ecceity) by means of experiential (or, more accurately, its intentive) relation to that corporeal being which embodies it.

In lieu of an abstract, here is a brief excerpt of the content:Journal of the History of Philosophy 41.3 (2003) 415-416 [Access article in PDF] Tad M. Schmaltz. Radical Cartesianism: The French Reception of Descartes. Cambridge: Cambridge University Press, 2002. Pp. xiv + 288. Cloth, $65.00.More than fifty years ago Richard H. Popkin urged historians of philosophy to work on secondary figures in philosophy, in part for their own sake, but also because the true shape of philosophy and the (...) development of major figures can be understood only through examination of the intellectual milieu out of which they arose. Among others he specifically mentioned Robert Desgabets, Jean Du Hamel, Simon Foucher, Pierre-Daniel Huet, Pierre-Sylvain Regis, and Henricus Regius. Now in Radical Cartesianism, Tad Schmaltz has provided a masterful and erudite study of these and other philosophers who are minor now but were major in their day. The importance of this study is not just that it illuminates the metaphysics of Descartes, Spinoza, and Malebranche, and clarifies the relationship of these philosophers to Arnauld, Jansenism, Plato, and the Aristotelian scholasticism of the day, but also that it opens to view an intricate and significant body of thought. The radical Cartesianism Schmaltz examines addresses and provides solutions to problems of the relationship between mind and body, between man and God, and between ideas and the external world that continue to engage philosophers today. Schmaltz concludes his study with the suggestion that these philosophers might have had more latter-day influence if larger historical events, in particular the death of Louis XIV and the subsequent relaxation of attacks on Jansenism (and on supposed Jansenist Cartesianism) had not led to interest in matters other than the Eucharist and the nature of the soul that were major issues among the radical Cartesians and their opponents.But were any of these radical Cartesians actually Cartesians? If, as Schmaltz says, the metaphysical core of Cartesianism is Descartes's doctrine that "the essence of body consists in extension and that the essence of mind consists in thought" (10), then most of his followers were not radical Cartesians, but rather heretical Cartesians. They rebelled against as many of Descartes's doctrines as they accepted. Schmaltz's careful expositions, analyses, comparisons, correlations, and extrapolations of their arguments and positions make up the bulk of his book. The detail, command of the material, insight, and breadth of Schmaltz's exposition is on an order of magnitude above previous work on these figures and will stand for a long time as a challenge to the next few generations of scholars.But if so many of these figures alter Descartes's metaphysics so radically, why do they still designate themselves as Cartesians? The major reason is that while Cartesian metaphysics was in disarray, Cartesian science was flourishing. Regius is the model. He said (directly to Descartes) that metaphysics is inessential to science, that matters of God and certainty about the existence of the external world could and should be left to faith. What was liberating during the third quarter of the century in The Netherlands and in the fourth quarter in France was Descartes's scientific method of posing hypotheses and testing them with experiments. You will never get certainty this way, but already science was advancing by leaps and bounds. Christian Huygens, who as a boy had known Descartes, belittled the man's metaphysics, but was one of the greatest and most successful practitioners of the [End Page 415] Cartesian scientific method of his time. What remains to be written is a study of late-seventeenth-century Cartesian science that is as excellent and comprehensive as Schmaltz's study of the Cartesian metaphysics of the time. Here are some problems Descartes set up that are of particular concern to the philosophers of the time. If God can do anything, even make contradictions true, then why could he not make you think you exist even when you do not? How could you think of something that does not exist? Because your thoughts have a temporal dimension, and time depends on motion, and motion pertains only to material bodies, how could you... (shrink)

Many of the errors that occur in children' subtraction are due to the use of incorrect strategies rather than to the incorrect recall of number facts. A production system is presented for performing written subtraction which is consistent with an earlier analysis of the nature of such a cognitive skill. Most of the incorrect strategies used by schoolchildren can be accounted for in a principled way by simple changes in the production system, such as the omission of individual rules or (...) the inclusion of rules appropriate to other arithmetical tasks. The production system model is evaluated against a corpus of over 1500 subtraction problems done by 10‐year olds and is shown to account for about two‐thirds of the (nonnumber fact) errors. It also provides an alternative, simpler interpretation of the subtraction errors analysed by Brown and Burton (1978). Some implications for teaching are discussed. (shrink)

Physicians have for some time been questioning the prevailing view of medicine as applied biology. It is urged that medicine needs to be reconceived so as to provide appropriate emphasis on the patient's experience and understanding of illness. After reviewing these arguments and the scientific paradigm underlying the received view in light of certain themes in medicine's history and of current thinking, Pellegrino's thesis is analyzed: medicine should be understood as an inherently moral enterprise, a form of praxis focused on (...) "the healing relationship". Understanding the illness experience and the professed healer's "compassion" supports Pellegrino's view, and suggests that the healing relationship is perhaps best conceived as a form of dialogue.
