Researchers from across the social sciences have found consistent deviations from the predictions of the canonical model of self-interest in hundreds of experiments from around the world. This research, however, cannot determine whether the uniformity results from universal patterns of human behavior or from the limited cultural variation available among the university students used in virtually all prior experimental work. To address this, we undertook a cross-cultural study of behavior in ultimatum, public goods, and dictator games in a range of (...) small-scale societies exhibiting a wide variety of economic and cultural conditions. We found, first, that the canonical model – based on self-interest – fails in all of the societies studied. Second, our data reveal substantially more behavioral variability across social groups than has been found in previous research. Third, group-level differences in economic organization and the structure of social interactions explain a substantial portion of the behavioral variation across societies: the higher the degree of market integration and the higher the payoffs to cooperation in everyday life, the greater the level of prosociality expressed in experimental games. Fourth, the available individual-level economic and demographic variables do not consistently explain game behavior, either within or across groups. Fifth, in many cases experimental play appears to reflect the common interactional patterns of everyday life. Key Words: altruism; cooperation; cross-cultural research; experimental economics; game theory; ultimatum game; public goods game; self-interest. (shrink)

We would like to thank the commentators for their generous comments, valuable insights and helpful suggestions. We begin this response by discussing the selfishness axiom and the importance of the preferences, beliefs, and constraints framework as a way of modeling some of the proximate influences on human behavior. Next, we broaden the discussion to ultimate-level (that is evolutionary) explanations, where we review and clarify gene-culture coevolutionary theory, and then tackle the possibility that evolutionary approaches that exclude culture might be sufficient (...) to explain the data. Finally, we consider various methodological and epistemological concerns expressed by our commentators. (shrink)

The current ethical norms of genomic biobanking creating and maintaining large repositories of human DNA and/or associated data for biomedical research have generated criticism from every angle, at both the practical and theoretical levels. The traditional research model has involved investigators seeking biospecimens for specific purposes that they can describe and disclose to prospective subjects, from whom they can then seek informed consent. In the case of many biobanks, however, the institution that collects and maintains the biospecimens may not itself (...) be directly involved in research, instead banking the biospecimens and associated data for other researchers. Moreover, the future uses of biospecimens may be unknown, if not unknowable, at the time of collection. Biobanking may thus stretch the meanings of inform and consent to their breaking point: if you cannot inform subjects about what their biospecimens will be used for, what can they consent to? Given that informed consent by individual subjects is the ethical gold standard, the seeming dilution of the concept in the context of biobanking is a profound problem. (shrink)

Published one year after Forget Foucault, In the Shadow of the Silent Majorities may be the most important sociopolitical manifesto of the twentieth century: it calls for nothing less than the end of both sociology and politics. Disenfranchised revolutionaries hoped to reach the masses directly through spectacular actions, but their message merely played into the hands of the media and the state. In a media society meaning has no meaning anymore; communication merely communicates itself. Jean Baudrillard uses this last outburst (...) of ideological terrorism in Europe to showcase the end of the "Social." Once invoked by Marx as the motor of history, the masses no longer have sociological reality. In the electronic media society, all the masses can do--and all they will do--is enjoy the spectacle. In the Shadow of the Silent Majorities takes to its ultimate conclusion the "end of ideologies" experienced in Europe after the Soviet invasion of Hungary and the death of revolutionary illusions after May 1968. Ideological terrorism doesn't represent anything anymore, writes Baudrillard, not even itself. It is just the last hysterical reaction to discredited political illusions. (shrink)

Andres Bonifacio is a household name in the history of the Philippines.His name has been included into many discussion and controversies revolvingover his identity as the Father of the Revolution and being the founder ofKataastaasang, Kagalanggalangag Katipunan . His poems serve as legaciesthat can unlock what kind of person is Andres. Through his poems, he expressedreflections about the situation of the Indios during the time of colonization andthe rage of the revolution. This descriptive study analyzed four selected poemsof Andres Bonifacio (...) and sought to find a new insight into the poems through a Neo-Marxist perspective using a Neo-Marxist lens, specifically the theory of cultural hegemony by Antonio Gramsci. Based on the content analysis of hispoems, it was found out that Bonifacio was affected by the false consciousnesspropagated by the colonizers during the Spanish settlement in the country. Italso answered the question whether Bonifacio is a patriotic man or a nationalistichero. Keywords: Literature, revolution, neo-marxism, poems, Andres Bonifacio, descriptiveresearch, Philippines.

The development of factor markets has opened Chinese agriculture for the penetration of capitalism. This new round of rural transformation—China’s agrarian transition— raises the agrarian question in the Chinese context. This study investigates how capitalist forms and relations of production transform agricultural production and the peasantry class in rural China. The authors identify six forms of nonpeasant agricultural production, compare the labor regimes and direct producers’ socioeconomic statuses across these forms, and evaluate the role of China’s land-rights institution in shaping (...) these forms. The empirical investigation presents three main findings: Peasant differentiation : capitalist forms of agricultural production differentiate peasants into a variety of new class positions. Market-based stratification: producers in capitalist agriculture are primarily stratified by their positions in labor and land markets; their socioeconomic statuses are linked with their varying degrees of proletarianization. Institutional mediation: rural China’s dual-track land system plays a crucial role in shaping the diverse and unique forms of capitalist production. (shrink)

One way to characterise the difference between analytic and Continental political philosophy concerns the different roles played by normative and descriptive analysis in each case. This article argues that, even though Michel Foucault’s genealogy of liberal and neoliberal governmentality and John Rawls’s political liberalism involve different articulations of normative and descriptive concerns, they are complementary rather than antithetical to one another. The argument is developed in three stages: first, by suggesting that Foucault offers a way to conceive of public (...) reason as a historical phenomenon. Second, it is suggested that both Rawls and Foucault allow us to consider rights as historical and particular rather than a-historical and universal. Third, it is argued that Foucault’s genealogy of modern liberal government illuminates some of the tensions and some of the alternatives within the liberal tradition in relation to the concept of political legitimacy.

This paper explores possible important relationships and sympathies between Amartya Sen’s Capabilities Approach framework for understanding the human condition and the educational ideas of John Dewey and Paolo Freire. All three focus on the importance of democratic values in a fair, well-functioning society, while Sen and Freire especially explore the difficulties and possibilities of oppressed populations. Sen suggests that all humans have a right to choice in determining their life trajectories and should be provided with the tools that allow (...) them to flourish. Both education and democratic values play important roles in creating the types of context that allow individuals and communities to recognize a wide array of human capabilities. We suggest here that the theories of Dewey and Freire offer avenues through educational processes for developing these contexts for expanded human capability. Dewey suggests an educational approach that stresses democratic values and the ability and willingness of individuals to reach out towards new possibilities. Freire stresses the idea of praxis playing a central role in education—a focus on the cycle of everyday action, reflection, and re-creation of action that leads to productive changes in life trajectories. We argue that Sen, Dewey, and Freire together help to offer a new way of understanding education in the twenty-first century. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:THE SUBSTANTIAL UNITY OF MATERIAL SUBSTANCES ACCORDING TO JOHN POINSOT JOHN D. KRONEN The University of St. Thomas St. Paul, Minnesota EVERY SUBSTANCE metaphysician must answer several difficult questions peculiar to his or her ontology. In this paper I will examine John Poinsot's answer to two of these questions, one concerning the nature of the form of substantial composites, and one concerning which material objects are (...) substantial composites. I shall argue that Poinsot's answers to these questions show the untenability of a structuralist view of substantial form and of a reductive materialist view of living beings. But before considering these questions I must briefly outline Poinsot's view of what the general nature of substance is, as explained in his treatise on material logic.1 Poinsot's Account of Substance in General In the section of his Material Logic concerned with the categories Poinsot gives a succinct account of the nature of substance 1 Cursus Philosophicus thomisticus; vol. I, Ars logicae prima et secunda pars, ed. P. Beato Reiser (Turin, Italy: Marietti, 1820), Q. XV, pp. 523-527. It should be noted that I am not concerned in this paper with describing either the psychological origin of the notion of substance, or of justifying it against phenomenalism. My only aim is to show how such a view of substance leads to a certain notion of form when it is applied, so to speak, to material objects. For an interesting account of the origin of the concept of substance in Poinsot see John Deely, Tractatus De Signis: The Semiotic of John Poinsot (Los Angeles, Berkeley, and London: The University of California Press, 1985), p. 86, n. 16. Deely takes it that Poinsot has a deeper categorial scheme than that of Aristotle from which the latter's scheme "emerges," as it were. In this article, then, I am not concerned with that deeper scheme which Deely refers to in this interesting note. 599 600 JOHN D. KRONEN in general and of its relation to the supposit and to the act of existing. He notes that by " substance " narrowly considered is meant that kind of essence to "which it is due to exist in itself as opposed to that kind to which it is due to exist in another" (i.e., an accident).2 He defends this as the primary " definition " 3 of substance against the other definition of it which is " that which stands under accidents," on the grounds that a thing must exist in itself, at least ontologically speaking, before it can support accidents 4 and that to define substance as that which supports accidents is to define it in relation to other things, not itself. This point is important because many modern and contemporary philosophers who have attacked the notion of substance have done so by arguing that there are no beings which stand under accidents. For Poinsot this attack, even if successful, would show that there are no accidents, not that there are no substances. Poinsot insists that " substance " connotes a quiddity to which to exist in itself is due since actual existence does not belong to the essence of any created thing.5 Further, Poinsot insists that to exist in itself " connotes more than a mere negation of existing in another; rather it connotes a positive perfection." This is because to exist in a dependent way is to exist in an imperfect way, so to exist independently must be to exist in a more perfect way.6 Finally, Poinsot distinguishes between the substance and the supposit. The substance is the complete nature of the thing, while 2 Ibid., p. 523. a " Substance " as a supreme genus cannot strictly be defined since it cannot be differentiated from any higher genus. 4 Haec autem proprietas existendi per se intelligitur vel secundum considerationem absolutam et in ordine ad se, et sic dicitur subsistens, quasi non indignes alio ut sustentetur, sed in se sistens; vel dicitur secundum habitudinem ad alia, quatenus ilia sustentat in esse, et sic dicitur non solum subsistens, sed etiam substans.

It analyses the differences and similarities between post-structuralist philosophy and liberal political theory. It explores the egalitarian and democratic presuppositions of post-structuralist critical strategies and the non-metaphysical and historical conception of liberalism that we find in the late Rawls. It also discusses the relevant works of Jacques Derrida, Richard Rorty, and John Rawls.

In lieu of an abstract, here is a brief excerpt of the content:Aquinas's Ethics beyond Thomistic Virtue Ethics:The Gifts of the Holy Spirit, Spiritual Instinct, and Complete Human PerfectionJohn BerkmanThis paper offers a new reading and interpretation of Aquinas's doctrine of the gifts of the Holy Spirit. In the contemporary Thomist literature on ethics, there is far more discussion—and a far more developed discussion—of the nature and role of a virtue-habitus than a gift-habitus. Why might there be so little discussion (...) of the gifts and their distinctive habitus? Is it because Aquinas devotes many more questions to the virtues than to the gifts? Is it because the majority of self-professed Thomist ethicists have not been taught the gifts, and are either unaware or have merely a notional awareness that the gifts have a principle of action distinct from and superior to that of the virtues?1 Regardless of the reason, this paper seeks to mitigate the current paucity of analysis of the gifts and the gift-habitus.This paper will discuss Aquinas's doctrine of the gifts of the Holy Spirit from a resolutely gift-centered perspective. I do so because discussions of the gifts often presume a virtue-centered perspective. That is, treatments of the gifts typically interpret what Aquinas says about the gifts through the lens of a pre-existing virtue framework, the gifts then being made to fit into that pre-existing framework. I will argue that we see this not only in interpretations of Aquinas on the gifts, but also in English translations of the Summa theologiae [ST] on the question of the gifts. [End Page 47]As a result, in contemporary scholarship on Aquinas's ethics, the virtues typically receive extended treatment, whereas the gifts of the Holy Spirit receive no treatment at all. And when the gifts are addressed, their treatment is brief, with the main point being that the gifts provide assistance to the virtues, like a spiritual butler. In the best-case scenario, the gifts are like Jeeves to the virtues' Bertie—undoubtedly wiser, but rarely listened to.The paper is divided into four sections. The first section compares and contrasts a gift-habitus and a vinue-habitus. The second section focuses on Aquinas's notion of instinctus. The instinct of the Holy Spirit (divine instinct) is the principle of motion Aquinas associates with the gifts of the Holy Spirit (ST I-II, q. 68, aa. 1–2). I argue that—contrary to the judgment of most commentators—instinctus is a highly appropriate term to describe the character of the work of the Holy Spirit. In this section I also show how Aquinas's doctrine of instinctus has been made "invisible" in part by various translations of the ST, including the translation of Fr. Shapcote.2In the third section, I analyze Aquinas' argument that the gifts are more perfective of human beings than the virtues (ST I-II, q. 68, a. 8). This analysis also constitutes a "case study" of the ways in which Shapcote's translation (the dominant English translation for the last hundred years) contributes to misunderstandings of Aquinas's views on the relationship between the gifts and the virtues. In comparing and contrasting the virtues and gifts, an original part of my argument is my claim that, while charity sometimes operates from a virtue-habitus, at other times it operates according to a gift-habitus. Commentators have failed to adequately account for the fact that truly perfect (simpliciter) charity cannot be attained solely by the operations of virtue. The ultimate expression of charity requires a habitus superior to a virtue-habitus.3 While the wayfarer's expression of charity is always in one [End Page 48] sense a gift from God, in that it relies on God's grace, as the wayfarer grows in charity, charity increasingly functions as a gift of the Holy Spirit, or perhaps the form of all the gifts.4The fourth and final section focuses on how the gifts and infused virtues operate in the wayfarer who is growing in spiritual maturity. I argue that, although infused virtue-habitus and gift-habitus are given at baptism, facility in either typically grows slowly. Increasing facility in... (shrink)

The aim of this paper is to show the relationship between John XXIII and Robert K. Greenleaf’s understanding of leadership. By taking into consideration Greenleaf’s theory of servant-leadership – from conceptualization to model development – and Larry Spears’ influential rubric of ten servant-leadership characteristics, we will show how servant-leadership theory goes in line with that of John XXIII when both are based on a notion of the common good and human dignity.

This paper refutes two important and influential views in one fell stroke. The first is G.E.

Both views run aground the possibility of being justified in accepting eliminativism about belief. A corollary is that a principle recently defended by John Williams is also false, (...) namely, that justification to believe Q entails justification to believe that you believe Q. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:OBJECT AND INTENTION IN MORAL JUDGMENTS ACCORDING TO AQUINAS JOHN FINNIS U'flkueTBity Oollege Unwersity of Oa:ford INTENTION IS OF END, choice is of means. A human aict ~s specified by (and s? is co.rrect:ly describe~ in terms of) its end. A human act IS specified by (and so Is correctly described in terms of) its object. An a:ct which is bad by reason of its object cannot be (...) justified by its end (its: good intention ). A human a:ct is specified by (and so is correctly described in iterms of) its intention.... Such a sequence of statements of St. Thomas ought to leave an impression of confusion. That impression would be heightened by the traditional representation of his analysis of acting in a schema of 12 terms signifying a sequence of psychological acts involved in willing and doing something. For in this analysis, intention seems to precede ·deliberating, judging, and choosing, and so, as deliberating, judging, and choosing often present themselves to consciousness distinctly, intention is presented in this analysis as if it were a distinct content of consciousness. When intention is so conceived, iit becomes possible to imagine that one can, so to speak, choose to direct (an) intention to or withhold it from the various aspects of one's chosen behavior, e.g. it.hose consequences which one foresees and welcomes or those one chooses to bring about onJ.y with regret. To some contemporary moralists, such approving or regretting of consequences is precisely what engages or disengages one's will and thus one's responsibility; what Christians or Jews used to regard as immoral can be uprightly done if done merely as a means to good ends and only with reluctance, I JOHN FINNIS regret, disapproval, i.e. if in no way approved or adopted as an end, i.e. if not really intended.1 Other modern moralists deny that one's responsibility for consequences of deliberate behavior can be so dependent on an inner ruct of intending (as distinct from the choosing and doing) ; they judge one responsible for everything one deliberately and with foresight causes.2 So they too reject the " doctrine " of double effect which Christian moralists had articulated as a development or codification of the elements of St. Thomas's discussion of self-defense, a disoussion whose first premise is that a human ad is specified (i.e. identified for the purposes of moral assessment) by its intention. Today there are other moralists again who combine the two foregoing lines of thought: they reject the doctrine of double effect as giving exaggernted importance to choice (means) over intention (end); one should take into account alil foreseeable consequences of one's chorce and ensure that it is likely to have a greater proportion of good than of bad consequences, and one must never approve (intend) any bad consequences -one may never deliberately cause them as ends hut only as means, means which one deliberwtely causes, not for their own sake, hut only for the sake of those proportionately greater good (or less bad) consequences which one does intend.8 1 Cf., e.g., Richard McCormick, S.J., "Medicaid and.Abortion," Theological Studies 45 (1984): 716-717. 2 Cf.

In concrete applications of probability, statistical investigation gives us knowledge of some probabilities, but we generally want to know many others that are not directly revealed by our data. For instance, we may know prob(P/Q) (the probability of P given Q) and prob(P/R), but what we really want is prob(P/Q&R), and we may not have the data required to assess that directly. The probability calculus is of no help here. Given prob(P/Q) and prob(P/R), it is consistent with the probability calculus (...) for prob(P/Q&R) to have any value between 0 and 1. Is there any way to make a reasonable estimate of the value of prob(P/Q&R)? A related problem occurs when probability practitioners adopt undefended assumptions of statistical independence simply on the basis of not seeing any connection between two propositions. This is common practice, but its justification has eluded probability theorists, and researchers are typically apologetic about making such assumptions. Is there any way to defend the practice? This paper shows that on a certain conception of probability — nomic probability — there are principles of “probable probabilities” that license inferences of the above sort. These are principles telling us that although certain inferences from probabilities to probabilities are not deductively valid, nevertheless the second-order probability of their yielding correct results is 1. This makes it defeasibly reasonable to make the inferences. Thus I argue that it is defeasibly reasonable to assume statistical independence when we have no information to the contrary. And I show that there is a function Y(r,s:a) such that if prob(P/Q) = r, prob(P/R) = s, and prob(P/U) = a (where U is our background knowledge) then it is defeasibly reasonable to expect that prob(P/Q&R) = Y(r,s:a). Numerous other defeasible inferences are licensed by similar principles of probable probabilities.. (shrink)

Saul Kripke has made fundamental contributions to a variety of areas of logic, and his name is attached to a corresponding variety of objects and results. 1 For philosophers, by far the most important examples are ‘Kripke models’, which have been adopted as the standard type of models for modal and related non-classical logics. What follows is an elementary introduction to Kripke’s contributions in this area, intended to prepare the reader to tackle more formal treatments elsewhere.2 2. WHAT IS A (...) MODEL THEORY? Traditionally, a statement is regarded as logically valid if it is an instance of a logically valid form, where a form is regarded as logically valid if every instance is true. In modern logic, forms are represented by formulas involving letters and special symbols, and logicians seek therefore to define a notion of model and a notion of a formula’s truth in a model in such a way that every instance of a form will be true if and only if a formula representing that form is true in every model. Thus the unsurveyably vast range of instances can be replaced for purposes of logical evaluation by the range of models, which may be more tractable theoretically and perhaps practically. Consideration of the familiar case of classical sentential logic should make these ideas clear. Here a formula, say (p & q) ∨ ¬p ∨ ¬q, will be valid if for all statements P.. (shrink)

It is generally accepted that farmers manage a complex farm system. In this article we seek answers to the following questions. How do farmers perceive and understand their farm system? Are they sufficiently aware of their farm system that they are able to represent it in the form of a map? The research reported describes how causal mapping was applied to sheep/beef farmers in New Zealand and shows that farmers can create maps of their farm systems in ways that allow (...) expression of both individual maps and the formation of group maps which represent the general character of farm systems. A group map was made for all the farmers studied and for subgroups using conventional, integrated, and organic management systems. The results are discussed in terms of the depth of meaning associated with individual elements of the map, map complexity and the limitations of causal mapping. Causal mapping has the potential to contribute to our knowledge of how farmers see their farm systems, and this can benefit farmers and other stakeholders concerned with the management of farms and their economic and environmental performance.

Subcreative sets, introduced by Blum, are known to coincide with the effectively speedable sets. Subcreative sets are shown to be the complete sets with respect to S-reducibility, a special case of Turing reducibility. Thus a set is effectively speedable exactly when it contains the solution to the halting problem in an easily decodable form. Several characterizations of subcreative sets are given, including the solution of an open problem of Blum, and are used to locate the subcreative sets with respect to (...) the complete sets of other reducibilities. It is shown that q-cylindrification is an order-preserving map from the r.e. T-degrees to the r.e. S-degrees. Consequently, T-complete sets are precisely the r.e. sets whose q-cylindrifications are S-complete. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:AQUINAS ON VIRTUE AND THE GOODS OF FORTUNE* JOHN BOWLIN University of Tulsa Tulsa, Oklahoma I T IS NOW commonplace to say that Aristotle considers good fortune useful, if not indispensable, for the acquisition and exercise of the virtues, and for the success of virtuous choices.1 Aquinas obviously draws upon Aristotle's treatment of the virtues as he develops his own, and yet he says relatively little about fortune's (...) influence upon the life of virtue.2 This reticence is puzzling, in part because it seems reasonable to expect that Aquinas would address a matter so central to an Aristotelian account of the virtues, but also because fortune's effect upon that account is hardly benign. If the life of virtue requires good fortune, then the voluntary character of virtuous habits and actions is threatened. And for someone with Aquinas's theological commitments the threat comes packaged with additional worries, equally troubling. For it implies that Providence, which governs fortune's ways (STh I, q. 116, a. 1), acts as fortune does, offering virtue and its benefits to some, while unjustly denying them to others. These are difficulties that cannot be escaped by ignoring 'A version of this paper was presented on 7 January 1994 in Chicago at the annual meeting of the Society of Christian Ethics. I would like to thank John Carmody, Victor Preller, Jeffrey Stout, and John Taylor for their comments and criticisms. The usual disclaimers apply. 1 See, e.g., Nancy Sherman, The Fabric ofCharacter: Aristotle's Theory of Virtue (New York: Oxford University Press, 1989), chapter 2. 2 Aquinas's interpreters have tended to say even less. For this reason I develop Aquinas's account of the relation between the virtues and the goods of fortune by looking to a number of recent interpretations of Aristotle's account. 537 538 JOHN BOWLIN them, or so it would seem. We must ask, therefore, whether Aquinas fails to see the problems that fortune creates for his treatment of the virtues, or, alternatively, whether his treatment of the virtues offers reasons that warrant his silence.3 Of course, there are multiple questions here insofar as fortune's potential influence upon the life of virtue is as complex as that life. Virtues are acquired, retained, and exercised, and fortune can affect each process in different ways, just as it can affect the success of virtuous choices. Add to this the fact that different virtues are subject to fortune in different ways and to different degrees and suddenly the possibilities for inquiry are vast. Indeed, the thought of undertaking a comprehensive inquiry tempts hubris. Mine will be more modest, asking simply this: what kind and what measure of external goods, those distributed by fortune, are required in order to pursue a life of virtue? l. REJECTED OPTIONS Aquinas lists the following external goods: wealth, power, honor, fame, a good country, a good name, and perhaps a few others (STh I-II, q. 2, a. 1-4; II-II, q. 108, a. 3).4 He considers them instrumental goods, which the virtuous must possess in some measure if they hope to achieve their ends consistently (STh I-II, q. 2, a. 1; II-II, q. 83, a. 6; q. 118, a. 1). He writes, "For imperfect happiness, such as can be had in this life, external goods are necessary, not as belonging to the essence of happiness, but by serving as instruments to happiness, which consists in an operation of virtue" (STh I-II, q. 4, a. 7). Often their usefulness to the virtuous is direct, when, for example, they serve as a necessary instrument of a certain kind of virtuous action. The liberal, for instance, cannot successfully exercise their virtue without at least some wealth (STh II-II, q. 117, a. 3). In other contexts their usefulness is indirect, their aid to the virtuous mediated by some other condition. For instance, 3 Attending to Aquinas's silences is, of course, an effort inspired by Joseph Pieper's classic, The Silence of St. Thomas (New York: Pantheon, 1957). 4 I follow Aquinas and use "goods of fortune" and "external goods" interchangeably (STh I-II, q. 2, a. 4).

Probability plays an essential role in many branches of AI, where it is typically assumed that we have a complete probability distribution when addressing a problem.

These are principles telling us that although certain inferences from probabilities to probabilities are not deductively valid, nevertheless the second-order probability of their yielding correct results is 1. This makes it defeasibly reasonable to make the inferences. Thus I argue that it is defeasibly reasonable to assume statistical independence when we have no information to the contrary. And I show that there is a function Y(r,s:a) such that if prob(P/Q) = r, prob(P/R) = s, and prob(P/U) = a (where U is our background knowledge) then it is defeasibly reasonable to expect that prob(P/Q&R) = Y(r,s:a)..

In 1949 the great logician Kurt Gödel constructed the first mathematical models of the universe in which travel into the past is, in theory at least, possible. Within the framework of Einstein’s general theory of relativity Gödel produced cosmological solutions to Einstein’s field equations which contain closed time-like curves, that is, curves in spacetime which, despite being closed, still represent possible paths of bodies. An object moving along such a path would travel back into its own past, to the very (...) moment at which it “began” the journey. More generally, Gödel showed that, in his “universe”, for any two points P and Q on a body’s track through spacetime, such that P temporally precedes Q, there is a timelike curve linking P and Q on which Q temporally precedes P. This means that, in principle at least, one could board a “time machine” and travel to any point of the past. Gödel inferred, in consonance with the views of Parmenides, Kant and the modern idealists, that under these circumstances there could be no such thing as an objective lapse of time, that time or, more generally, change, is an illusion arising from our special mode of perception. For consider an observer initially at point P. At point Q he boards a time machine and travels back to point P, taking time t′′ to do so. In that case, according to his own clock, t′ – t + t′′ > 0 seconds have elapsed, and yet an identical clock left at P would show that 0 seconds have elapsed. In short, there has been no “objective” lapse of time at all. Gödel remarks that in his universe this situation is typical: for every possible definition of an “objective” time one could travel into regions which are past according to that definition. He continues. (shrink)

An American Ethic takes the basis for American life - freedom - and describes the reality behind that abstraction, the transcendent nature of man. The book analyzes freedom and communication along with the inalienable rights and obligations that necessarily flow from the transcendent nature of man. It explains and distinguishes the usual norms of morality: natural law, positive law, religion, and conscience; and then proceeds to discuss contemporary moral issues: sanction for crime, animal rights, business ethics, sexual morality, homosexuality, and (...) abortion. In light of that analysis, the book critiques three recent and well-known works of ethics: Robert Pirsig's Lila, James Q. Wilson's The Moral Sense, and Peter Singer's Practical Ethics. (shrink)

Early commentators and traditionists embed and amplify Q 2:102—an enigmatic allusion to angelic complicity in the transmission of esoteric knowledge to humankind—within a rich layer of interpretive lore frequently bearing the rubric “Tale of Hārūt and Mārūt.” A close study of this verse alongside its external narrative embellishments uncovers a wealth of structural and contextual motifs that suggestively link the “Tale” with biblical and parascriptural myths about “fallen angels” and their perceived role in the corruption of antediluvian humanity. The present (...) article catalogs a representative number of these motifs, speculates about their mode of transmission, and offers some guidelines for analyzing the different versions of the “Tale” that surface centuries later in medieval Jewish interpretive and mystical literature. Particular attention is devoted to unpacking the identity of the woman who is responsible for the seduction of the angels. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:TRANSCENDENTAL THOMISM AND THE THOMISTIC TEXTS JOHN F. x. KNASAS Genter for Thomistic Studies Houston, Temas SOME THIRTY YEARS ago in the journal Thought, there appeared an article by Fr. Joseph Donceel, S.J., entitled " A Thomistic Misapprehension? " Its thesis is that American Thomism had seen too much of the a posteriori in Aquinas's noetic.1 In fact the interpretation was so a posteriori that it bordered on (...) empiricism and positivism. Donceel intends to balance the American understanding of Aquinas by spotlighting various Thomistic texts that speak of an a priori contribution of the intellect to human knowledge. Donceel is merely calling attention to something that some outstanding European Thomists, e.g., Defever, Marechal, and Rahner have known for some time. Donceel's " balanced" interpretation is what is called Transcendental Thomism. In sum, the position claims that the human intellect is not so complete a tabula rasa that it fails to make an a priori contribution to the data of sensation. This contribution is the intellect's very dynamism to Infinite Being. The dynamism has a constitutive role in human experience. Swept up within this intellectual torrent, the data of sensation stand before us in consciousness as finite and limited. So " objectified " the data are disposed for the traditional abstvactive account of the specific and generic natures. After the Second Vatican Council, Thomism generally fell into disrepute among American Catholic intellectuals. Phi1 Joseph Donceel, " A Thomistic Misapprehension?" Thought, 32 (1957) : 189. 81 82 JOHN F. X. KNASAS losophy departments " pluralized." Their members represented analytic, existential, and process philosophy.2 If Thomism remained vibrant, it was in the a priori strain. Both on the philosophical and theological levels, it was at home with the pluralism tha.t marked the time.3 The current emphasis on political activism, however, ha:s caused even Transcendental Thomism to suffer an eclipse. In the heat of political struggle, Transcendental Thomism, too, appears decadent and bourgeois. The case can be made, though, that the uncovering of the intellect's a priori dynamism to the Infinite was a crucial move for liberationists. Gutierrez notes 4 that the Transcendental Thomist understanding of the human intellect posits a single finality for human nature. The traditional distinction between the temporal and eternal planes loses meaning. Human history becomes salvation history. In this way, then, Transcendental Thomism continues to exercise its influence. This paper investigates the purported Thomistic texts expressing an apriorism. The texts cited by Donceel are all found in Marechal's Cahier V.5 There MarechaI mentions many others besides. Hence, my paper will use the Marechalian collection. My treatment focuses upon the texts that are seemingly most a priori. I. A central text for Marechal is De Veritate, q.l, a.4, ad 5m (first set). Aquinas remarks: 2 See "Is a 'Catholic' Philosophy Department Possible? " by the Committee on Research (Thomas I.angan, K. I,. Schmitz, Jude P. Dougherty) of the ACPA (HJ78). 3 On Transcendental Thomism's capacity to admit a theological pluralism without falling into a relativism, see Gerald A.

TRANSCENDENTAL THOMISM AND THE TEXTS 83 The truth by which the soul passes judgment on all things is the first truth; for, just as from the truth of the divine intellect there flow into the angelic intellects those: intelligible species by which angels know all things, so does the truth of the first principles by which we judge everything proceed from the truth of the divine intellect as from its exemplary cause. Since we can judge by means of the truth of these first principles only insofar as this truth is a likeness of the first truth, we are said to judge everything according to the first truth.6 The text illustrates a " dynamic exemplarism " in Aquinas...

Empiricism is the doctrine that all knowledge has a strictly observational basis. Rationalism is the doctrine that least some knowledge has non-observational, purely conceptual basis. In the present work, empiricism is carefully considered and found to have four dire shortcomings: -/- (1) Empiricism cannot account for our knowledge of what doesn't exist, let alone what cannot exist. -/- (2) Empiricism cannot account for our knowledge of dependence-relations, given (1), coupled with the fact that 'P depends on Q' is equivalent with (...) 'not-Q either necessitates or is dispositive of not-P.' -/- (3) Empiricism cannot account for our knowledge of the past, the future, or the possible, given (2), coupled with the fact knowledge of any of these domains requires knowledge of conditional truths (truths of the form "if P, then Q") and therefore of dependence-relations. -/- (4) Empiricism cannot by itself apprise us of any truths, given (3), coupled with the fact that knowledge of conditional truths is necessary to recognize the truths implicit in any body of sensory data. -/- The arguments of key empiricists are closely examined. Special attention is paid to George Berkeley's arguments for idealism ('to be is to be perceive/conceived'). It is shown that, although Berkeley's arguments fail, profound insights are embedded in the very sophisms that vitiate those same arguments, the three most important ones being: -/- (i) That data-modelling and truth-identification at least sometimes coalesce, -/- (ii) That scientific theories are at least sometimes capable of being represented as interpreted formal calculi, and -/- (iii) That when theoretical terms are defined contextually, as opposed to directly, otherwise unintelligible assertions acquire scientific significance. -/- Further, it is shown that, even though Berkeley's arguments for idealism fall through, he himself deserves credit for identifying the principle in terms of which the fallacies in those arguments are to be understood, namely: -/- (*) It is not sensory experience alone that yields awareness of the outside world, but sensory experience coupled with awareness on the subject's part of relational invariances holding among the objects of those awareness. -/- Thus, perceptual knowledge is knowledge of invariances. And, to make a point hinted at in Berkeley's work, knowledge of laws is meta-perceptual knowledge, given that laws of nature are invariances holding among the invariances holding among the objects of perception.

Appropriate for a conference relating philosophy and education, we seek ways more faithful than the truth-functional hook to understand and represent that ordinary-language conditional which we use in, e.g., modus ponens, and that conditional’s remote and counterfactual counterparts, and also the proper negations of all three. Such a logic might obviate the paradoxes caused by T-F representation, and be educationally fruitful. William and Martha Kneale and Gilbert Ryle assist us: "In the hypothetical case in which p, it is inferable, on (...) the basis that p and at least in the given context, that q." "Inferable" is explained. This paraphrase is the foundation of the logic of hypothetical inferability. It generates the negative but non-TF device "hib", followed by a bracketed conjunction. This is an enriched negative: "hib " is stronger than "-," and "-hib" offers us "-hib," weaker than "p. -q." Thus equipped, we can test deductive arguments by the CI method explained, and explode paradoxes. The paraphrase, "hib," and the CI method are fruitful in training students to understand this conditional, and to demonstrate genuine validity or invalidity. (shrink)
