The general concept of a causal system has been basic in scientific thought. It may be formulated as follows. The system in question possesses certain measurable attributes such as those of dimensions, temperature, and so forth. In the case of a causal system, it is affirmed that the subsequent development of the system from a known initial condition—that is, a condition in which the measurable variables have known values—is uniquely determined by these values. More definitely, the value of these same (...) variables after any interval of time depends only on the initial values of the variables and the time interval which has elapsed. (shrink)

The following statement is a report of the Committee on Philosophy in Education of the American Philosophical Association and was approved by the Association's Board of Officers in September, 1959. The Committee was composed of the following: C. W. Hendel, Chairman, H. G. Alexander, R. M. Chisholm, Max Fisch, Lucius Garvin, Douglas Morgan, A. E. Murphy, Charner Perry, and R. G. Turnbull. Primary responsibility for the preparation of this report belonged to a subcommittee composed of Roderick M. Chisholm, Chairman, H. (...) G. Alexander, Lewis Hahn, Paul C. Hayner, and Charles W. Hendel. (shrink)

In a recent article ‘The Problem of Natural Theology’, Professor N. H. G. Robinson has considered the requirements of a ‘genuinely empirical natural theology’. For the first section of it, a very clear sorting-out of recent debates on the ontological argument, I have nothing but admiration. It ends with the question: ‘Granted that if we think of God we must think of him as necessarily existing, why must we think of God at all?’, followed by the comment: ‘We seem thrown, (...) without any prospect of rest, between apriorism and [Barthian] empiricism’. Robinson is rightly dissatisfied with that situation, and in his second section he raises the question whether there cannot be an approach to God which the debates on the ontological arguments have overlooked and which may be properly called an ‘empirical’ one, free from Barthian presuppositions. He finds what seems to be such an approach in Professor E. L. Mascall's Existence and Analogy but concludes that it is in fact after all a form of ‘rationalism’. In the third section he criticises Professor T. F. Torrance's defence of Barth's position in a way which seems to me most satisfactory, and in the fourth he makes his own positive proposals. With these I am in substantial agreement. It is only his account of Mascall's position, in particular at the end of his second section, which seems to call for critical comment. (shrink)

Although death by neurologic criteria is legally recognized throughout the United States, state laws and clinical practice vary concerning three key issues: the medical standards used to determine death by neurologic criteria, management of family objections before determination of death by neurologic criteria, and management of religious objections to declaration of death by neurologic criteria. The American Academy of Neurology and other medical stakeholder organizations involved in the determination of death by neurologic criteria have undertaken concerted action to address variation (...) in clinical practice in order to ensure the integrity of brain death determination. To complement this effort, state policymakers must revise legislation on the use of neurologic criteria to declare death. We review the legal history and current laws regarding neurologic criteria to declare death and offer proposed revisions to the Uniform Determination of Death Act and the rationale for these recommendations.

"My experience is what I agree to attend to," wrote William James (1890) nearly a century ago in his Principles of Psychology. Although certainly not the first to recognize the importance of attention in man's experience--poets and philosophers throughout history have touched upon the concept in one way or another-James deserves credit for having accorded attention a central role in the systematic study of the mind. With the advancement of psychology since that time, except during the behaviorist digression, the concept (...) of attention has been an integral part of many prominent theories dealing with learning, thinking, and other aspects of cognitive functioning. Indeed, attention is an important determinant of experience from birth throughout development. This has been an implicit assumption underlying our view of cognition since the writings of Charles Darwin (1897) and Wilhelm Preyer (1888) as well as James, all of whom offered provocative insights about the developing child's commerce with the environment. Al though systematic research on attention in children was slow to pick up during the early part of this century, interest in the developmental study of attention has expanded enormously in recent years.

This brief enquiry concerns two main questions: how and why Sulpicius' law differed from a similar prior rogation of the same year, which he had vetoed; and the probable authorship of the latter.

Discussion starts from Tac. Ann. 4.56, where in a.d. 26 ambassadors from Smyrna, with those of other communities in Asia, present their city's case for selection as the site of the province's cult of Tiberius, and plead a lengthy record of loyalty and past officia to Rome, dating back to the foundation at Smyrna of a temple to Urbs Roma in 195 B.C. amid the tensions with Antiochus III of Syria. Tacitus proceeds.

On any view, the Aristotelian account of Athens' constitutional history between victory over the Persian invaders and Ephialtes' reforms of the Areopagus and indeed beyond must be regarded as factually grudging and difficult to follow. Worse, current orthodoxy1 convicts it of a major chronological blunder for assigning a part in those reforms, which it places securely and beyond doubt correctly in the archonship of Konon, to Themistokles, who had been ostracized from the city perhaps as early as 473/2 and in (...) any case by 467/62.

In this last of our selection of papers from the London Medical Group Conference on Pain, Gilbert Lewis, through his experiences of living in New Guinea describes to us the various rites, rituals and uses of pain in societies other than our own. He outlines, by example, how what often seems the natural behaviour to us for helping a sufferer in fact, can make matters far worse for other peoples. Although different societies approach the problem of pain from many (...) routes the aim of all is to relieve pain for the sufferers. If the sufferer says he feels relief then that is surely what counts. (shrink)

Although many researchers theorize that primitive numerosity processing abilities may lay the foundation for whole number concepts, other classes of numbers, like fractions, are sometimes assumed to be inaccessible to primitive architectures. This research presents evidence that the automatic processing of nonsymbolic magnitudes affects processing of symbolic fractions. Participants completed modified Stroop tasks in which they selected the larger of two symbolic fractions while the ratios of the fonts in which the fractions were printed and the overall sizes of the (...) compared fractions were manipulated as irrelevant dimensions. Participants were slower and less accurate when nonsymbolic dimensions of printed fractions were incongruent with the symbolic comparison decision. Results indicated a robust basic sensitivity to nonsymbolic ratios that exceeds prior conceptions about the accessibility of fraction values. Results also indicated a congruity effect for overall fraction size, contrary to findings of prior research. These findings have implications for extending theory about the nature of human number sense and mathematical cognition more generally. (shrink)

Women have consistently higher levels of disgust than men. This sex difference is substantial in magnitude, highly replicable, emerges with diverse assessment methods, and affects a wide array of outcomes—including job selection, mate choice, food aversions, and psychological disorders. Despite the importance of this far-reaching sex difference, sound theoretical explanations have lagged behind the empirical discoveries. In this article, we focus on the evolutionary-functional level of analysis, outlining hypotheses capable of explaining why women have higher levels of disgust than men. (...) We present four hypotheses for sexual disgust and six for pathogen disgust, along with testable predictions. Discussion focuses on additional new hypotheses and on future research capable of adjudicating among these competing, but not mutually exclusive, hypotheses. (shrink)
