In his Introduction to Logic (...) 1 Irving Copi raises a problem with two of these definitions which he believes forces him to limit the range of propositions which can be used in the square of opposition. Since contrary propositions can both be false, but the falsity of a necessarily true proposition is not possible, a necessarily true proposition has no contrary. Therefore, only contingent propositions can be contraries. Subcontrary propositions can both be true, but the truth of a necessarily false proposition is not possible.2 This problem is rarely raised in other logic texts, but, it is interesting to note, it is mentioned by a number of neoscholastic philosophers, for example, P. Nicholas Russo,3 Rev. H. Grenier,4 1 Irving M. Copi, Introduction to Logic (New York: Macmillan, 1986), pp. 178-179. Copi first introduced this problem in the fifth edition of his work on the basis of an article by David H. Sanford entitled " Contraries and Subcontraries,'' Nous 2 (1968) : 95-96. Sanford argues that the most reasonable way to resolve the problem of necessary propositions is to assume that contingent propositions comprise the square of opposition. 2 Copi, pp. 178-179. 8 Nicholas Russo, Summa Philosophica (Boston: Apud Marlier et Socios, 1[;85), p. 23. 4 Henri Grenier, Thomistic Philosophy, Vol. I (Charlottetown, Canada: St. Dunstan's University, 1950), p. 69. 427 428 MARK ROBERTS G. Sanseverino,5 Jacques Maritain,6 F.-X. Maquart,7 P. Coffey,8 and others.9 (It is also mentioned by Bishop Whately.10 ) Each of these philosophers makes necessarily true or false propositions an exception to the definition of contrary and subcontrary propositions. The reason is they and Copi interpret the definitions of contrary and subcontrary propositions to mean that the falsity of each contrary proposition is possible and the truth of each subcontrary proposition is possible. It should be mentioned, however, that the position of the philosophers cited above is not entirely the same as Copi's. Copi reasons that these definitions imply that necessary propositions have no contrary or subcontrary. The other philosophers believe that necessary propositions can be contraries and subcontraries. Thus, in the case of necessary propositions contrary and subcontrary propositions are, instead, defined merely in terms of their quantity and quality, not by whether or not they can both be false or can both be true. In fact, Coffey and some of the other philosophers cited above assert that, when the propositions composing the square are necessary, one can infer the truth of the universal from the truth of 5 Gaietano Sanseverino, Philosophia Christiana, Vol. II (Neapoli: Vincentii Manfredi, 1862), pp. DCCXXXVIII ff. 6 J.

This monograph is designed to provide an introduction to the principal areas of tense logic. Many of the developments in this ever-growing field have been intentionally excluded to fulfill this aim. Length also dictated a choice between the alternative notations of A. N. Prior and Nicholas Rescher - two pioneers of the subject. I choose Prior's because of the syntactical parallels with the language it symbolizes and its close ties with other branches of logi cal theory, especially modal logic. The (...) first chapter presents a wider view of the material than later chapters. Several lines of development are consequently not followed through the remainder of the book, most notably metric systems. Although it is import ant to recognize that the unadorned Prior-symbolism can be enriched in vari ous ways it is an advanced subject as to how to actually carry off these enrichments. Readers desiring more information are referred to the appropri ate literature. Specialists will notice that only the first of several quantifi cational versions of tense logic is proven complete in the final chapter. Again constraints of space are partly to blame. The proof for the 'star' systems is wildly complex and at the time of this writing is not yet ready for publi cation. (shrink)

The T/t locus was a major focus of study by mouse geneticists during the 20th century. In the 70s, as the study of cell surface antigens controlling transplantation antigens was taking off, several laboratories hypothesized that alleles of this locus would control cell surface antigens important for embryonic development. One such antigen, the embryonal carcinoma F9 antigen was said to be an example. Other antigens were described on sperm and embryos that were said to be controlled by alleles at the (...) T/t complex. These findings were later found to be false. The history of the findings and their refutation is described. (shrink)

This book argues that the primary function of human thinking in language is to make judgments, which are logical-normative connections of concepts. Robert Abele points out that this presupposes cognitive conditions that cannot be accounted for by empirical-linguistic analyses of language content or social conditions alone. Judgments rather assume both reason and a unified subject, and this requires recognition of a Kantian-type of transcendental dimension to them. Judgments are related to perception in that both are syntheses, defined as the (...) unity of representations according to a rule/form. Perceptual syntheses are simultaneously pre-linguistic and proto-rational, and the understanding makes these syntheses conceptually and thus self-consciously explicit. Abele concludes with a transcendental critique of postmodernism and what its deflationary view of ontological categories—such as the unified and reasoning subject—has done to political thinking. He presents an alternative that calls for a return to normativity and a recognition of reason, objectivity, and the universality of principles. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:348 BOOK REVIEWS to God's commandments is "the way and condition of salvation" (VS # 12). Now obedience to the commandments entails, in addition to a good motivation or a willingness to strive, the conformity of an action's object to the specifying content of the commandment. What is the significance of a commandment to honor one's father and mother, if it does not specify actions? The commandments of God (...) specify what kinds of action are, or are not, in conformity with the true good of man. In his analysis of the moral act, the Pope holds that the object of the act is "the primary and decisive element for moral judgment" (VS # 79). Actions which by the nature of their object are unable to be ordered to man's true end can never be "good" actions. Further, he notes that acts, even individual acts, are determinative of the goodness or badness of the person. These points are summarized nicely in the following passage: Activity is morally good when it attests to and expresses the voluntary ordering of the person to his ultimate end and the conformity of a concrete action with the human good as it is acknowledged in its truth by reason. If the object of the concrete action is not in harmony with the true good of the person, the choice of that action makes our will and ourselves morally evil, thus putting us in conflict with our ultimate end, the supreme good, God himself (VS # 72). I believe that Keenan's study commendably highlights the freedom of the will in the order of exercise, and its power to exercise dominion over the intellect in the order of specification. Keenan also insightfully emphasizes the central role of the love of God as the root of our striving to live well. Yet any willing can only be consequent to some knowing. Further, the willingness to strive and be determined, if it is good, is a willingness to be determined, or specified, by the true good known by reason and faith. This willingness, which is a crucial element in moral goodness, must be completed by actions in conformity with the true good. Human goodness is in freely, and lovingly, living out the truth of human nature and its end. The Catholic University of America Washington, D.C. JOHN A. D. CUDDEBACK Moral Absolutes: Tradition, Revision, and Truth. By JOHN FINNIS. Washington, D.C.: The Catholic University of America Press, 1991. Pp. 113. $24.95 (cloth), $9.95 (paper). Not long after his conversion to Roman Catholicism, Alasdair MacIntyre told a group of Catholic bishops: " As a matter of autobio- BOOK REVIEWS 349 graphical fact, I came to the conclusion that there were exceptionless and binding [moral] norms prior to and quite independently of any faith in Divine Revelation." Within the Church Macintyre entered, however, there existed, and exists, widespread doubt and confusion about "moral absolutes" or " exceptionless moral norms." Certain eminent Catholic moral theologians today dissent from Pope John Paul's teaching that " there exist acts which per se and in themselves, independently of circumstances, are always seriously wrong by reason of their object." In the face of this dissent, John Finnis has produced a powerful philosophical and theological defense of the papal teaching. Moral Absolutes presents the 1988 Michael J. McGivney Lectures which Finnis delivered at the John Paul II Institute for Studies on Marriage and the Family. The hook consists of four chapters: "Foundations," "Clarifications," "Christian Witness," and "Challenge and Response." Like Macintyre, Finnis maintains that the authority of scripture and tradition supplement reason's grasp of certain specific types of act as intrinsically wicked and, therefore, never to he performed. Although his goal is to vindicate the proposition that there are moral absolutes, rather than to say which, or even how many, moral norms qualify as " exceptionless " (and therefore as, in the relevant sense of the term, " absolute "), his examples include norms against abortion (and, more generally, the direct killing of innocent human beings), adultery, fornication, contraception, homosexual sex, blasphemy, and disclaimer of the faith. As Finnis observes, the Church's tradition of proclaiming these norms and their absoluteness is "massively solid." Against certain neoscholastic... (shrink)

What makes it hard to dance? Twentieth-century phenomenologists drew attention to the importance of the lived body, and dance is the art form for which the lived body is literally central. Why then isn’t dance the easiest art form to engage in? Phenomenologists are drawn to situations where a phenomenon breaks down, which can open insights into the phenomenon itself. Here the phenomenon is the ability to dance where one might normally expect to. This paper invokes Marion Milner’s book On (...) Not Being Able to Paint. It discusses views of David Kleinberg-Levin, Maxine Sheets-Johnstone, Iris Young, and others. Parallel to Heidegger’s notion of the Enframing, what causes the disappearing dimensions of animate formanimate form is the Interring. (shrink)

Seven features which in practice seem to differentiate belief systems from knowledge systems are discussed. These are: nonconsensuality, “existence beliefs,” alternative worlds, evaluative components, episodic material, unboundedness, and variable credences. Each of these features gives rise to challenging representation problems. Progress on any of these problems within artificial intelligence would be helpful in the study of knowledge systems as well as belief systems, inasmuch as the distinction between the two types of systems is not absolute.

We argue that all human beings have a special type of dignity which is the basis for (1) the obligation all of us have not to kill them, (2) the obligation to take their well-being into account when we act, and (3) even the obligation to treat them as we would have them treat us, and indeed, that all human beings are equal in fundamental dignity. We give reasons to oppose the position that only some human beings, because of their (...) possession of certain characteristics in addition to their humanity (for example, an immediately exercisable capacity for self-consciousness, or for rational deliberation), have full moral worth. What distinguishes human beings from other animals, what makes human beings persons rather than things, is their rational nature, and human beings are rational creatures by virtue of possessing natural capacities for conceptual thought, deliberation, and free choice, that is, the natural capacity to shape their own lives.

Contemporary liberal thinkers commonly suppose that there is something in principle unjust about the legal prohibition of putatively victimless crimes. Here Robert P. George defends the traditional justification of morals legislation against criticisms advanced by leading liberal theorists. He argues that such legislation can play a legitimate role in maintaining a moral environment conducive to virtue and inhospitable to at least some forms of vice. Among the liberal critics of morals legislation whose views George considers are Ronald Dworkin, Jeremy (...) Waldron, David A.J. Richards, and Joseph Raz. He also considers the influential modern justification for morals legislation offered by Patrick Devlin as an alternative to the traditional approach. George closes with a sketch of a "pluralistic perfectionist" theory of civil liberties and public morality, showing that it is fully compatible with a defense of morals legislation. Making Men Moral will interest legal scholars and political theorists as well as theologians and philosophers focusing on questions of social justice and political morality. (shrink)

Free markets alone do not work effectively to solve certain kinds of human problems, such as education, old age care, or disaster relief. Nor have markets ever been the sole solution to the psychological challenges of death, suffering, or injustice. Instead, we find a major role for the non-market institutions of society - the family, the state, and social institutions. The first in-depth anthropological study of charities in contemporary Chinese societies, this book focuses on the unique ways that religious groups (...) have helped to solve the problems of social well-being. Using comparative case studies in China, Taiwan and Malaysia during the 1980s and onwards, it identifies new forms of religious philanthropy as well as new ideas of social 'good', including different forms of political merit-making, new forms of civic selfhood, and the rise of innovative social forms, including increased leadership by women. The book finally argues that the spread of these ideas is an incomplete process, with many alternative notions of goodness continuing to be influential. (shrink)

"Crease’s brilliantly exploited theatrical analogy places scientific theorizing back into the wider context of experimental inquiry." —Robert C. Scharff Crease attacks the "mystical" account of experimentation embraced by the positivist and Kantian varieties of philosophy of science, according to which experimentation takes a backseat to theory.

The rational choice assumption that any chosen behavior can be understood as optimizing material self?interest is not borne out by psychological research. Expressive motives, for example, are prominent in the symbols of politics, in social relationships, and in the arts of persuasion. Moreover, instrumentality is a mindset that is learned (perhaps overlearned), and can be situationally manipulated; because it is valued in our society, it provides a privileged vocabulary for justifying behaviors that may have been performed for other reasons, and (...) encourages the illusory belief in the universality of rational choice.

Research on social influences often distinguishes between social and quality incentives to ascribe meaning to the value that popularity conveys. This study examines the neural correlates of those incentives through which popularity influences preferences. This research reports an functional magnetic resonance imaging experiment and a behavioral task in which respondents evaluated popular products with three focus perspectives; unspecified focus, focus on social aspects, and focus on quality. The results show that value derived with a social focus reflects inferences of approval (...) and reward value, and positively affects preferences. Value derived with a quality focus reflects inferences of quality and negatively affects preferences. This study provides evidence of two distinct inferential routes on both a neurological level, represented by different regions in the brain, and a behavioral level. These results provide the first evidence that a single popularity cue can in different ways influence the value derived from product popularity. (shrink)

"Public reason" is one of the central concepts in modern liberal political theory. As articulated by John Rawls, it presents a way to overcome the difficulties created by intractable differences among citizens' religious and moral beliefs by strictly confining the place of such convictions in the public sphere. Identifying this conception as a key point of conflict, this book presents a debate among contemporary natural law and liberal political theorists on the definition and validity of the idea of public reason. (...) Its distinguished contributors examine the consequences of interpreting public reason more broadly as "right reason," according to natural law theory, versus understanding it in the narrower sense in which Rawls intended. They test public reason by examining its implications for current issues, confronting the questions of abortion and slavery and matters relating to citizenship. This energetic exchange advances our understanding of both Rawls's contribution to political philosophy and the lasting relevance of natural law. It provides new insights into crucial issues facing society today as it points to new ways of thinking about political theory and practice. (shrink)

QBism is an interpretation of quantum mechanics that posits quantum probabilities as subjective Bayesian probabilities, whence its name. By avoiding experientially unfulfilled speculations about what exists prior to measurement, QBism seems to make a close encounter with the phenomenological method. What follows is an interview with QBism’s founder and principal champion, the physicist Christopher Fuchs.

For some time now, commentators in and out of the scientific community have been expressing concern over the direction of scientific research. Cogent critics have labeled it excessively commercial, out of touch with its “pure,” public-spirited roots, and generally too much a creature of its entrepreneurial, self-interested times. In most if not all of this hand-wringing, the scientific community's growing reliance on intellectual property rights, especially patents, looms large. Indeed, for many the pursuit of patents is emblematic of just what (...) is rotten in the republic of science today. (shrink)

There is no question, of course, that music is a temporal art. Stravinsky, noting that it is inconceivable apart from the elements of sound and time, classifies it quite simply as "a certain organization in time, a chrononomy."1 His definition stands as part of a long and honored tradition that encompasses such diverse figures as Racine, Lessing, and Schopenhauer. Schopenhauer, putting the case in its strongest terms, remarks that music is "perceived solely in and through time, to the complete exclusion (...) of space," thus making explicit the opposition between time and space and ruling out the latter as a possible area for legitimate musical experience. Yet anyone familiar with the philosophical and theoretical literature dealing with music must be struck by the persistence with which spatial terminology and categories appear. Indeed, it would seem to be impossible to talk about music at all without invoking spatial notions of one kind or another. Thus in discussing even the most elementary aspects of pitch organization—and among the musical elements, only pitch, we should remember, is uniquely musical—one finds it necessary to rely upon such spatially oriented oppositions as "up and down," "high and low," "small and large" , and so on. Space, then, pace Schopenhauer, apparently forms an inseparable part of the musical experience. · 1.

Our understanding of the sense of taste is largely based on research designed and interpreted in terms of the traditional four tastes: sweet, sour, salty, and bitter, and now a few more. This concept of basic tastes has no rational definition to test, and thus it has not been tested. As a demonstration, a preliminary attempt to test one common but arbitrary psychophysical definition of basic tastes is included in this article; that the basic tastes are unique in being able (...) to account for other tastes. This definition was falsified in that other stimuli do about as well as the basic words and stimuli. To the extent that this finding might show analogies with other studies of receptor, neural, and psychophysical phenomena, the validity of the century-long literature of the science of taste based on a few is called into question. The possible origins, meaning, and influence of this concept are discussed. Tests of the model with control studies are suggested in all areas of taste related to basic tastes. As a stronger alternative to the basic tradition, the advantages of the across-fiber pattern model are discussed; it is based on a rational data-based hypothesis, and has survived attempts at falsification. Such has found broad acceptance in many neural systems. (shrink)
