'Uncertainty and chance' is a subject with a broad span, in that there is no academic discipline or walk of life that is not beset by uncertainty and chance. In this book a range of approaches is represented by authors from varied disciplines: natural sciences, mathematics, social sciences and medical sciences. At one extreme, this volume is concerned with the foundations of probability. At the other extreme, we have scholars who acknowledge the concept of chance and uncertainty but do not (...) cope with it by means of systematic measurement or quantative analysis. (shrink)

This paper describes the origins of the logistic function and its history up to its adoption in bio-assay and the beginning of its wider acceptance in statistics, ca. 1950. The function was probably first invented in 1838 to describe population growth by the Belgian mathematician Verhulst, who gave it its name in 1845; but it was rediscovered independently several times over in the next eighty years, both for this purpose and for the description of autocatalytic chemical reactions. Its adoption in (...) an altogether different role in bio-assay has been determined decisively by the individual actions and personal histories of a few scholars: the widespread acceptance of the growth function is due to Pearl and Reed, the general recognition of Verhulst’s primacy to Yule, and the introduction of the function in bio-assay to Berkson.

In this paper I discuss Nancey Murphy’s nonreductive physicalist perspective on personal identity and eschatological resurrection offered in her recent work, Bodies and Souls, or Spirited Bodies? I argue that if we take Murphy to be presenting actual metaphysical positions on these issues, it is very difficult to see how they go together coherently. Contrary to Murphy’s explicit claim to be presenting metaphysical criteria for personal identity, I argue that it appears she is instead offering an epistemological or psychological account (...) of identity. I conclude that Murphy may need to modify or reject either her criteria for personal numerical identity or her view of the resurrection in order to consistently hold the other. Alternately, she could view this inconsistency as a failure of the underlying physicalist assumptions of her “scientific research program” and thus reject her physicalist assumptions altogether.

In the past decades, reductionism has dominated both research directions and funding policies in clinical psychology and psychiatry. The intense search for the biological basis of mental disorders, however, has not resulted in conclusive reductionist explanations of psychopathology. Recently, network models have been proposed as an alternative framework for the analysis of mental disorders, in which mental disorders arise from the causal interplay between symptoms. In this target article, we show that this conceptualization can help explain why reductionist approaches in (...) psychiatry and clinical psychology are on the wrong track. First, symptom networks preclude the identification of a common cause of symptomatology with a neurobiological condition; in symptom networks, there is no such common cause. Second, symptom network relations depend on the content of mental states and, as such, feature intentionality. Third, the strength of network relations is highly likely to depend partially on cultural and historical contexts as well as external mechanisms in the environment. Taken together, these properties suggest that, if mental disorders are indeed networks of causally related symptoms, reductionist accounts cannot achieve the level of success associated with reductionist disease models in modern medicine. As an alternative strategy, we propose to interpret network structures in terms of D. C. Dennett's (1987) notion ofreal patterns, and suggest that, instead of being reducible to a biological basis, mental disorders feature biological and psychological factors that are deeply intertwined in feedback loops. This suggests that neither psychological nor biological levels can claim causal or explanatory priority, and that a holistic research strategy is necessary for progress in the study of mental disorders.

Patronizing the Public is the first detailed and comprehensive examination of how American philanthropy has transformed culture, communication, and the humanities. Drawing on an impressive range of archival and secondary sources, the chapters in the volume shed light on philanthropic foundations have shaped numerous fields, including film, television, radio, journalism, drama, local history, museums, as well as art and the humanities in general.

One of the central critiques of the bourgeois conception of public holds that, in its implicit claim to universality, it fails to account for the material particularities of social groups and for the variety of possible rationalities. Some theorists have aimed to solve this problem by describing particular publics and particular rationalities based on racial, ethnic, gender, or political identities. While particularist public models represent difference in protest of the totalizing and counterfactual valence of a bourgeois conceptualization of public, they (...) fail to acknowledge that glossing difference is fundamental to the function of and the authorizing power of public, as it is marshalled by speakers. By analogizing Perelman and Olbrechts-Tyteca's universal audience with public, this paper (a) introduces the public metonym, a rhetorically productive counterfactual totality that glosses the material particularities of social groups, (b) critiques the particularist approach to the paradox of public, (c) introduces the resistance metonym as a rhetorically-minded alternative, and (d) clarifies distinctions among projects that claim to address a common object called pUblic.

Light speed, c = 3 × 108 meters per second, is the ultimate speed limit of the universe. The welltested physics orthodoxy of special relativity tells us that nothing can go faster than c. When any massive object with rest mass M (taken to be in energy units) has velocity v=c (or relativistic velocity ß = v/c = 1), the object's mass-energy becomes infinite. This is because the relativistic..

Albert Einstein taught us that c, the speed of light in vacuum, is nature's ultimate speed limit, the highest speed at which matter, energy, and information can travel through space-time. In several AV columns I've discussed ways for getting around this annoying natural law, the law that SF writers and fans most wish to violate. Two AV columns discussed the possibility of getting around the lightspeed limit by popping through a trans-spatial wormhole shortcut. See [ Analog-6-89, "Wormholes and Time Machines"] (...) and [Analog-5-90, "Wormholes II: Getting There in No Time"]. Two others discussed the possible use the faster-than-light nonlocal handshaking implicit in quantum mechanics for FTL messages and travel. See [Analog-11-86, "The Quantum Handshake"] and [Analog-9-88, "Paradoxes and FTL Communication"]. Both of those methods, however, are beyond our present technology, and the latter is probably impossible. (shrink)

Particle physicists, over the last 50 years, have discovered several hundred strongly interacting “elementary” particles. The list of such particles begins with the proton and the p meson and goes up from there. We now understand that all of these particles are actually composites, formed from various combinations of quarks. Such particles are normally classified in two types. Mesons (the name implies medium weight) are particles with masses that go up from 140 MeV/c 2 and have an intrinsic angular momentum (...) or “spin” that is an integer in units of ħ (Planck’s constant over p). Baryons (the name implies heavy weight) are particles with masses that go up from 938 MeV/c 2 and have half-integer spin. This column is about the discovery of the pentaquark, a brand new form of matter that represents a new particle species, neither meson nor baryon, but a combination of both. (shrink)

Three standard psychometric tests were administered to parents who volunteered their children for a randomised, double-blind placebo-controlled trial of a new asthma drug and to a control group of parents whose children were eligible for the trial but had declined the invitation. The trial took place at a children's hospital in Australia. The subjects comprised 68 parents who had volunteered their children and 42 who had not, a participation rate of 94 per cent and 70 per cent, respectively. The responses (...) of these parents to the Gordon Survey of Interpersonal Values Questionnaire, the Coopersmith Self-Esteem Inventory and the Cattell Sixteen Personality Factor Questionnaire were analysed by computer. There was a marked difference between the psychological profiles of the two groups of parents. Volunteering parents put more value on benevolence while non-volunteering parents were more concerned with power and prestige. The self-esteem of volunteering parents was much lower than that of non-volunteering parents. Finally, volunteering parents were more introverted, exhibited greater anxiety and low supergo, while non-volunteering parents appeared to have greater social confidence and emotional stability. Since an individual's values, self-esteem and personality may be important antecedents of behaviour, these findings suggest that parents who volunteer their children for clinical research are not only socially disadvantaged and emotionally vulnerable, but may also be psychologically predisposed to volunteering. Furthermore, these findings provide evidence for the existence of a psychosocial 'filter' effect of the informed consent procedure, which may be discouraging the better educated, more privileged and psychologically resilient members of society from participation as research subjects.

This target article draws together two groups of experimental studies on the control of human movement through peripheral feedback and centrally generated signals of motor commands. First, during natural movement, feedback from muscle, joint, and cutaneous afferents changes; in human subjects these changes have reflex and kinesthetic consequences. Recent psychophysical and microneurographic evidence suggests that joint and even cutaneous afferents may have a proprioceptive role. Second, the role of centrally generated motor commands in the control of normal movements and movements (...) following acute and chronic deafferentation is reviewed. There is increasing evidence that subjects can perceive their motor commands under various conditions, but that this is inadequate for normal movement; deficits in motor performance arise when the reliance on proprioceptive feedback is abolished either experimentally or because of pathology. During natural movement, the CNS appears to have access to functionally useful input from a range of peripheral receptors as well as from internally generated command signals. The unanswered questions that remain suggest a number of avenues for further research. (shrink)

This work belongs to what Adam Smith called "the theory of moral sentiments," in particular, it is concerned with the operation of sympathetic affections, which are termed "vicarious affects"; and their rationality and legitimate role in moral theory. Professor Rescher forcefully argues for the thesis that the crucial aspect of vicarious affects lies in their function as motivational factor or reason rather than as a cause of personal conduct. A formal machinery is proposed for the quantitative aspect of the workings (...) of vicarious affects and applied to the problem of the "prisoner’s dilemma." In the latter connection, Rescher shows with insight that there is really nothing paradoxical about the "prisoner’s dilemma." The apparent paradox arises only because the game theorist failed to distinguish sharply rationality and prudence. "It is a travesty... to construe rationality in terms of prudential self-advantage, for there is nothing in any way inherently unreasonable or irrational about a concern for others." "There is no reason why ’self-interest’ should not be construed in an enlightened and widened sense to include the interests of others, through the operation of the vicarious affects." Rescher also points out that there are two alternatives, other than prudence, to the "solution" of conflict interaction situations, i.e., negotiation and impartial arbitration, when both are construed as tacit rather than explicit processes. One chapter is devoted to a fuller analysis and defense of the "impartial arbiter" approach as superior to the negotiation approach, and followed by a sustained critique of utilitarian doctrine of morality. Complex distinctions and arguments are set forth. The fatal weakness of utilitarianism, of various versions, is said to lie in its failure to distinguish de facto utilities and de jure utilities. De jure utilities have rational warrant "exterior to the utilitarian perspective." "An evaluative assessment of the means by which such legitimate human ends as welfare requires the background of a larger vision of the ends of man." The final chapter elaborates this vision as Hegelian in character. While the gap between morality and self-interest is recognized, Rescher postulates as a regulative ideal "a reciprocal coordination of personal and social advantage." But this larger vision includes welfare-transcending considerations, e.g., the various ideals of the quality of life, those "higher" aspirations. "Excellence, dignity, and the sense of worth are its leading themes." In the Primacy of Practice, one finds a fuller discussion of moral excellence, but on the whole Rescher has not offered us a detailed account of this ideal dimension of morality. For the present work, at any rate, Rescher has succeeded in arguing for the significant role of vicarious affects in moral philosophy and its implication for the legitimacy of differential treatments based on personal relationships. It is hoped that, in some future work, Professor Rescher will systematically integrate this role of vicarious affects in an ideal moral theory.—A.S.C. (shrink)

This is a sustained attack on what the author termed "decido-phobia"—the fear of making fateful decisions. The book begins with an illuminating discussion of ten popular strategies of decido-phobia. Of particular interest to moral philosophy is the attack on "moral rationalism" which "claims that purely rational procedures can show what one ought to do or what would constitute a just society". "Moral irrationalism" is also criticized for ignoring the relevance of reasons "when one is confronted with fateful decision". An ethics (...) of autonomous men is proposed as an alternative to decido-phobia. This ethics involves four cardinal virtues of love, honesty, courage, and "humbition," the last a new coinage for "fusion of ambition and honesty." Both the concepts of justice and guilt are subjected to detailed criticism, since they constitute the chief obstacles on the road to autonomy. Unlike Kantian autonomy, Professor Kaufmann focuses on that which "consists of making with open eyes the decisions that give shape to one’s life". There is no need of Kantian maxims or categorical imperative. Autonomy involves a new integrity or high standards of honesty which consist in a sort of lived intellectual honesty that is characteristic of a mind that is open to alternatives and spirit of questions. Alienation is regarded as a price of autonomy. A searching critique of current conceptions of alienation is given in Chapter 6. The author recommends a creative autonomous way of life. In his concluding words "guilt is mired in the past, as is retributive justice. Distributive justice is struck in the present, but by the time it has figured out how to cope with that, it is dated. We must move beyond guilt and justice. We must give up the pleasant notion that we can have all good things at once. What is best is not things at all but creative autonomy". This is an important theme and requires closer scrutiny of its central arguments and its suggested alternative ethics of creative autonomy.—A.S.C. (shrink)

The book analyzes how one might philosophize about some of the most difficult and controversial issues in ethics and politics without abandoning either the demands of rigor or the joys of clear vistas.
