In this book, Yaqub describes a simple conception of truth and shows that it yields a semantical theory that accommodates the whole range of our seemingly conflicting intuitions about truth. This conception takes the Tarskian biconditionals as correctly and completely defining the notion of truth. The semantical theory, which is called the revision theory, that emerges from this conception paints a metaphysical picture of truth as a property whose applicability is given by a revision process rather than by a fixed (...) extension. The main advantage of this revision process is its ability to explain why truth seems in many cases almost redundant, in others substantial, and yet in others paradoxical. Yaub offers a comprehensive defense of the revision theory of truth by developing consistent and adequate formal semantics for languages in which all sorts of problematic sentences can be constructed. Yaqub concludes by introducing a logic of truth that further demonstrates the adequacy of the revision theory. (shrink)

Behavior that solves a problem is distinguished by the fact that it changes another part of the solver's behavior and is strengthened when it does so. Problem solving typically involves the construction of discriminative stimuli. Verbal responses produce especially useful stimuli, because they affect other people. As a culture formulates maxims, laws, grammar, and science, its members behave more effectively without direct or prolonged contact with the contingencies thus formulated. The culture solves problems for its members, and does so by (...) transmitting the verbal discriminative stimuli called rules. Induction, deduction, and the construction of models are ways of producing rules. Behavior that solves a problem may result from direct shaping by contingencies or from rules constructed either by the problem solver or by others. Because different controlling variables are involved, contingency-shaped behavior is never exactly like rule-governed behavior. The distinction must take account of a system which establishes certain contingencies of reinforcement, such as some part of the natural environment, a piece of equipment, or a verbal community; the behavior shaped and maintained by these contingencies; rules, derived from the contingencies, which specify discriminative stimuli, responses, and consequences, and the behavior occasioned by the rules.

In this target article the following hypotheses are discussed: (1) Colour is autonomous: a perceptuolinguistic and behavioural universal. (2) It is completely described by three independent attributes: hue, brightness, and saturation: (3) Phenomenologically and psychophysically there are four unique hues: red, green, blue, and yellow; (4) The unique hues are underpinned by two opponent psychophysical and/or neuronal channels: red/green, blue/yellow. The relevant literature is reviewed. We conclude: (i) Psychophysics and neurophysiology fail to set nontrivial constraints on colour categorization. (ii) Linguistic (...) evidence provides no grounds for the universality of basic colour categories. (iii) Neither the opponent hues red/green, blue/yellow nor hue, brightness, and saturation are intrinsic to a universal concept of colour. (iv) Colour is not autonomous. (shrink)

Brian Wormald provides a fundamental reappraisal of one of the most complex and innovative figures of the late-Elizabethan and Jacobean age. In the centuries since his death, Francis Bacon (1561-1626) has been perceived and studied as a promoter and prophet of the philosophy of science--natural science--but he saw himself also as a clarifier and promoter of what he called "policy" or the study and improvement of the structure and function of civil states. Mr. Wormald shows that Bacon was concerned equally (...) with the knowledge of the world of nature and with that of policy. The junction between the two enterprises was effected by his work in history; and in the end it was Bacon's conception and practice of history that provided the answer to his efforts to advance policy and natural philosophy.

The present author developed a calculus for the logic of ‘because’. In a recent paper in this journal, it has been claimed that the central inference rules for the logic are invalid and that the intuition upon which the rules are based is not accounted for. This note criticises these arguments and presents an independent argument in favour of the rules used in the logic.

The ethics of Wolfhart Pannenberg has a nomological dimension at its center. Based on the history of the natural law tradition, Pannenberg maintains the possibility of the natural law theory on the following five grounds. -/- The theological ground is his understanding of the Decalogue, the Sermon on the Mount, and the Pauline interpretation of the law. For its historical ground, Pannenberg articulates the natural law theories of Patristic theology and the theologies of Troeltsch and Brunner. The ontological ground is (...) the order of the world, which God established in the process of history. The anthropological ground is the mutuality of human society. The latter two dimensions are related to the epistemological ground, which is based on the hermeneutics of universal history. -/- Pannenberg attempts to combine the law, the gospel, and love in relation to the Kingdom of God. Thus, Pannenberg’s Kingdom ethics is nomological as well as eschatological. (shrink)

This is a description and analysis of the intellectual culture of the eighteenth-century Church of England. Challenging conventional perceptions of the Church as an intellectually moribund institution, the study traces the influence of thinkers such as Locke, Newton, Burke, and Gibbon on theological debate in England during this period.

This study provides current data on key questions about retraction of scientific articles. Findings confirm that the rate of retractions remains low but is increasing. The most commonly cited reason for retraction was research error or inability to reproduce results; the rate from research misconduct is an underestimate, since some retractions necessitated by research misconduct were reported as being due to inability to reproduce. Retraction by parties other than authors is increasing, especially for research misconduct. Although retractions are on average (...) occurring sooner after publication than in the past, citation analysis shows that they are not being recognised by subsequent users of the work. Findings suggest that editors and institutional officials are taking more responsibility for correcting the scientific record but that reasons published in the retraction notice are not always reliable. More aggressive means of notification to the scientific community appear to be necessary. (shrink)

The systems approach to niche presented herein stands as an example of the unifying potential of mathematical system theory when applied to concepts and principles of ecology. Beginning with subjective concepts from the naturalistic tradition, the niche was framed in the formalism of general system theory. So modeled, it appeared as a restriction of a more general construct, the environ. Both niches and environs are implementable in the context of ecosystem models, and with the growing ability of ecologists to construct (...) such models, system theoretic niches and environs both should serve in the future to clarify old problems of ecology, and make it possible to raise new classes of problems. The nature of niches, always difficult conceptually for the ecologist, may now give way to further development, both theoretical and empirical. (shrink)

This article concerns the validity of six canonical rules that institutional review boards use to constrain the behavior of investigators. These rules require investigators to design their studies in a scientifically valid way, not pay their subjects to take risks, minimize risks to their subjects, secure for their subjects access to effective interventions post-trial, not pay their subjects too much and allow their subjects to withdraw from the study unconditionally. Enforcement of these rules is problematic because there are other relationships (...) that seem to be like the investigator-subject relationship in all ethically relevant respects, such as the employer-employee and volunteer organizer-volunteer relationships, to which we would not dream of applying these same rules. Applying these rules in one context but not the others is a violation of ethical consistency I label “exceptionalism.” We should conclude that it is time to reexamine the validity of the six rules.

This article examines the new conceptualizing and thinking about privacy. It discusses older theories of privacy and explains why they became obsolete. It suggests that the reconceptualization of privacy was influenced by the developments in information technologies, radical changes in the relation between the sexes, and the intrusion of intimacy into the public realm. It describes the normative problems associated with privacy and differentiates the three dimensions of privacy: decisional privacy, informational privacy, and local privacy.

This paper owes its inspiration to a remark made by Professor M. Rostovtzeff; in a note in his Social and Economic History of the Roman Empire on the widespread social unrest of the first two centuries A.D., having cited other literary authorities such as Dio Chrysostom, Aelius Aristides, etc., he writes: ‘The social problem as such, the cleavage between the poor and the rich, occupies a prominent place in the dialogues of Lucian; he was fully aware of the importance of (...) the problem.’ No one, as far as I know, has attempted to collect and discuss the main passages in Lucian on this topic, and the latest writer on this aspect of Lucian reaches a conclusion quite opposed to Rostovtzeff and one which I believe to be wholly misleading. The aim of this paper is to collect and discuss the main references in Lucian to the social problem interpreting them in the light of Lucian's life and background, and the social and economic conditions of his age. In particular I shall stress the importance of the Cynic tradition as it bears on Lucian's attitude, but shall endeavour to show that this tradition is firmly rooted in practical politics and actual participation in social revolutionary movements and goes far beyond the repetition of mere ethical cliches generally ascribed to it.

This essay is a critical response to Loren Lomasky's essay in this volume: The essay argues that Lomasky both overestimates the value of eating meat and underestimates the harms to animals of practices surrounding meat eating. While Lomasky takes the fact that an animal would not have lived at all if it were not being raised for food to constitute a benefit for animals being so raised, this essay argues that it would be better for animals raised on factory farms (...) to have never been born. It also contends that Lomasky overstates his case regarding the benefits of meat eating for human well-being. While gastronomic experiences can enrich our lives, it would be a mistake to think that meat eating is indispensable to the enrichment of our lives; one canexperience the flourishing of eating well without eating animals.

From what has been argued, it should now be apparent how Heidegger's philosophy of the affect, its ontological disclosures and its relation to authenticity might be enlarged to meet certain marxist challenges. The most valuable instruction to be gained from these citicisms, I think, is that which Lukacs offers in the example of Szilasi's intuition of co-presence. Traditional phenomenology needs to enrich its investigations into the social and historical reality of situation. Kosik's point that Heideggerian authenticity lacks the crucial third (...) step (revolutionary change of society) is also profound but again, not incompatiblein se with Heidegger's concept. Alternatively, one might as easily say that Critical Marxism or any Marxist Humanism can still be enriched by certain Heideggerian insights. (shrink)

It appears to be a generally accepted opinion among modern historians that the expedition which the Athenians led up-Nile in 459 B.C. in support of the Egyptian insurrection against Persia was an exceptionally large one, numbering no less than 200 sail. Modern authors also seem to imply, though they may not say so explicitly, that the whole of this armada was involved in the catastrophe which overtook the rebels in 454 B.C.

‘Ivravit in mea uerba tota Italia sponte sua et me belli quo uici ad Actium ducem depoposcit.’ In these words the Emperor Augustus clearly meant to suggest that the war in which he got rid of Mark Antony was none of his making, but was imposed upon him by the free and self-determined action of the Italian nation. Modern historians have unanimously refused to regard Augustus as a passive instrument in the hands of the Roman people at large; yet they (...) have generally accepted his account of the oath-taking of 32 B.C. as the outcome of a spontaneous burst of enthusiasm in his behalf, which they interpret as the reflex result of the nation's resentment against Antony's un-Roman and treasonable behaviour.

The argument rests on earlier work questioning the Russellian separation of levels and arguing that Russellian levels should be taken to include the levels of particle and aggregate, and generality and detail. That earlier work argues from the non-separation of particle and aggregate that predictability is limited and that physics cannot come to an end. This leads to a view of the world as flux. Identifiable objects demanding explanation can only be temporary entities emerging from flux and explanation can only (...) be local and historical. This precludes explanation of totality and leads us to reject Leibniz’s question. Baldwin’s argument from possible worlds theory that a null world is possible is examined and questioned. Koon’s combination of the kalam argument with the grim reaper paradox is not queried but a way is found of circumventing it. It is noted in passing that the argument does not have the anti-theistic implications which may appear. (shrink)

There is a need to bring ethics and medical practice closer together, despite the risk and problems this may involve. Deontological ethics may promote sanctity of life considerations against the quality of life considerations favoured by consequentialists or utilitarians; while talk of respect for life and the value of life may point to more qualified ethical positions. This paper argues for a respect-for-life position, dismissing a utilitarian cost-benefit outlook as too simplistic; but an unqualified fixed principles approach is also ruled (...) out, both because of its unacceptable consequences in individual cases and also because of its reliance on the slippery slope argument which, it is argued, is logically and psychologically deficient. The case of genetic engineering provides an example in which the notion of respect may operate, but in which broad general principles also apply. A cautious conservatism towards accepted principles is recommended in the development of medical technologies. (shrink)

An attempt is made here to examine the analysis three political thinkers - Thomas Paine, William Godwin, and Jeremy Bentham have offered of the idea of equality. The inquiry underrtaken is philosophical and not historical in character, since no attempt is made either at tracing the influence ht the biographical-cum-intellectual level of one of them upon the other or at treating their ideas on equality as born out of their preoccupation with the same problem to which they give various answers (...) and which can therefore be considered within a single overall framework. Instead, each thinker is considered independently. And a study is undertaken of the way he understands equality, the way he justifies it, the sort of equality he considers most important and his reasons for this, the area of life he takes the idea of equality to illuminate, the manner in which he relates it to other ideas, etc.. In each case, a fairly coherent philosophy of equality is sought to be constructed out of their respective writings. These three thinkers are selected for two reasons. The idea of equality looms quite large in their thought; as such, it was felt that looking at their writings from the standpoint of equality may illuminate their certain features that may otherwise remain obscure or relatively underemphasized. Further, as they consider equality from different philosophical positions it was believed that a critical examination of their writings could, perhaps, point to the general merits and limitations of their respective positions in terms of equality. in chapter I, it is argued that there are distinct views of God discernible in Paine's writings, and that corresponding to them are three distinct views of equality, though only two of them are discussed by Paine at any length. in chapter II, it is argued that, though Godwin begins as a thoroughgoing rationalist, three are shifts in his general philosophical position, and that, with each shift, his ideas on truth, rationality and equality undergo important changes. Finally, in chapter III, it is argued that there are two distinct theories of equality in Bentham and that tension between them remains unresolved. (shrink)
