A comparative method of studying the biological bases of personality compares human trait dimensions with likely animal models in terms of genetic determination and common biological correlates. The approach is applied to the trait of sensation seeking, which is defined on the human level by a questionnaire, reports of experience, and observations of behavior, and on the animal level by general activity, behavior in novel situations, and certain types of naturalistic behavior in animal colonies. Moderately high genetic determination has been (...) found for human sensation seeking, and marked strain differences in rodents have been found in open-field behavior that may be related to basic differences in brain neurochemistry. Agonistic and sociable behaviors in both animals and humans and the trait measure of sensation seeking in humans have been related to certain common biological correlates such as gonadal hormones, monoamine oxidase (MAO), and augmenting of the cortical evoked potential.The monoamine systems in the rodent brain are involved in general activity, exploratory behavior, emotionality, socialization, dominance, sexual and consummately behaviors, and intracranial self-stimulation. Preliminary studies have related norepinephrine and enzymes involved in its production and degradation to human sensation seeking. A model is suggested that relates mood, behavioral activity, sociability, and clinical states to activity of the central catecholamine neurotransmitters and to neuroregulators and other transmitters that act in opposite ways on behavior or stabilize activity in the arousal systems. Stimulation and behavioral activity act on the catecholamine systems in a brain–behavior feedback loop. At optimal levels of catecholamine systems activity (CSA) mood is positive and activity and sociability are adaptive. At very low or very high levels of CSA mood is dysphoric, activity is restricted or stereotyped, and the organism is unsocial or aggressively antisocial. Novelty, in the absence of threat, may be rewarding through activation of noradrenergic neurons. (shrink)

New Principles of War: Enduring Truths with Timeless Examples argues that the currently recognized principles of war are flawed, and proposes a new set of principles to guide military leaders.

Despite our moral misgivings, retributive canons of justice-the return of evil to evildoers-remain entrenched in law, literature, and popular moral precept. In this wide-ranging examination of retribution, Marvin Henberg argues that the persistence and pervasiveness of this concept is best understood from a perspective of evolutionary naturalism. After tracing its origins in human biology and psychology, he shows how retribution has been treated historically in such diverse cultural expressions as law codes, scriptures, drama, poetry, philosophy, and novels. Henberg considers (...) retributive thought in light of contemporary moral theory and current social and political concerns and advances his own theory of the morality of legal punishment."Retribution is no single doctrine or unified set of doctrines, but rather a sprawling variety of doctrines, many of them at odds with one another," observes Henberg. He suggests that understanding retributive thought as the quest for solace in the face of suffering helps to explain its variable nature. Since there is no single defensible moral criterion for identifying exact retaliation, culture is more important than nature in selecting among retributive practices. Typically, some forms of retribution are culturally approved, while others are disapproved. In place of the mistaken tendency to think of legal punishment as morally justified, Henberg maintains that legal punishment should be thought of as morally permitted. Author note: Marvin Henberg is Professor and Chair of the Department of Philosophy and Director of the University Honors Program at the University of Idaho. (shrink)

This study was undertaken to investigate whether work variables identified in theory and research as being related to employee experiences/behaviours add to the understanding and explain employees' experiences of workplace harassment. The extent to which social cognitive theory (SCT), specifically moral disengagement, explains the processes by which work characteristics are related to harassment was also examined. The purpose of the study was to identify the presence of relationships among work characteristics, satisfaction, moral disengagement and workplace harassment. According to the results, (...) employees with negative opinions of their work tended to experience negative affect and to believe that it is acceptable to harm others. The results of this study provide evidence of (1) relationships between harassment and several workplace characteristics and (2) the applicability of SCT to the explanation of how work characteristics relate to harassment.

The primary objective of this paper is to introduce a new epistemic paradox that puts pressure on the claim that justification is closed under multi premise deduction. The first part of the paper will consider two well-known paradoxes—the lottery and the preface paradox—and outline two popular strategies for solving the paradoxes without denying closure. The second part will introduce a new, structurally related, paradox that is immune to these closure-preserving solutions. I will call this paradox, The Paradox of the Pill. (...) Seeing that the prominent closure-preserving solutions do not apply to the new paradox, I will argue that it presents a much stronger case against the claim that justification is closed under deduction than its two predecessors. Besides presenting a more robust counterexample to closure, the new paradox also reveals that the strategies that were previously thought to get closure out of trouble are not sufficiently general to achieve this task as they fail to apply to similar closure-threatening paradoxes in the same vicinity.

It seems to me that the ingredients of most theories both in Artificial Intelligence and in Psychology have been on the whole too minute, local, and unstructured to account–either practically or phenomenologically–for the effectiveness of common-sense thought. The "chunks" of reasoning, language, memory, and "perception" ought to be larger and more structured; their factual and procedural contents must be more intimately connected in order to explain the apparent power and speed of mental activities.

Recent years have seen the rise of a new family of non-probabilistic accounts of epistemic justification. According to these views—we may call them Normalcy Views—a belief in P is justified only if, given the evidence, there exists no normal world in which S falsely beliefs that P. This paper aims to raise some trouble for this new approach to justification by arguing that Normalcy Views, while initially attractive, give rise to problematic accounts of epistemic defeat. As we will see, on (...) Normalcy Views seemingly insignificant pieces of evidence turn out to have considerable defeating powers. This problem—I will call it the Easy-Defeat Problem—gives rise to a two-pronged challenge. First, it shows that the Normalcy View has counterintuitive implications and, second, it opens the door to an uncomfortable skeptical threat. (shrink)

In ordinary discourse we often attribute beliefs not just to individuals but also to groups. But can groups really have genuine beliefs? This paper considers but ultimately rejects one of the main arguments in support of the claim that groups can be genuine believers – the Argument From Interpretationism – and concludes that we have good reasons to be sceptical about the existence of group beliefs. According to the Argument From Interpretationism, roughly speaking, groups qualify as genuine believers because we (...) can interpret their behaviour in much the same way that we can interpret the behaviour of individuals. While this argument may seem initially attractive, I argue that it is ultimately unsuccessful. In particular, I argue that the argument is unsuccessful even if one is generally sympathetic towards interpretationism. The reason for this, as we will see, is that a number of problems arise when we try to apply the interpretationist strategy – originally formulated with individual subjects in mind – to plural subjects or groups. In showing why the Argument From Interpretationism fails, the paper also brings into focus some more general constraints on the scope and applicability of interpretationism. (shrink)

The primary aim of this paper is to defend the Lockean View—the view that a belief is epistemically justified iff it is highly probable—against a new family of objections. According to these objections, broadly speaking, the Lockean View ought to be abandoned because it is incompatible with, or difficult to square with, our judgments surrounding certain legal cases. I distinguish and explore three different versions of these objections—The Conviction Argument, the Argument from Assertion and Practical Reasoning, and the Comparative Probabilities (...) Argument—but argue that none of them are successful. I also present some very general reasons for being pessimistic about the overall strategy of using legal considerations to evaluate epistemic theories; as we will see, there are good reasons to think that many of the considerations relevant to legal theorizing are ultimately irrelevant to epistemic theorizing.

This is the first of several memos about how OLPC could initiate useful projects that then could grow without our further support—if adopted by groups in our Diaspora.

In this comprehensive study, Marvin Fox offers an approach to Moses Maimonides that illuminates the intersections of his philosophical, religious, and Jewish visions—ideas that have embattled readers of Maimonides since the twelfth century.

For many, Thomas Beauchamp and James Childress have elaborated moral reasoning by using the four principles whereby all substantive problems of medical ethics (and of ethics more generally) can be properly analysed and cogent philosophical solutions for the problems can be found. It seems that their ‘principlism’ gets updated, with better features being added during the course of the six editions of Principles of Biomedical Ethics. Nonetheless, Beauchamp and Childress seem to have been losing their way when it comes to (...) the common-morality justification, which is the epistemological (and perhaps metaphysical) backbone of their method, and this is shown more vividly in their most recent (2009) edition of Principles of Biomedical Ethics. The author points out what he calls the problem of ‘thick in status, thin in content’ in principlism. The problem exists because principlism cannot adequately explain how the prescriptive sense of common morality it supports is consistent with the existence of what Beauchamp and Childress call the ‘legitimate moral diversity in the world’. Because of this problem, first, the practical end that principlism allegedly accomplishes (ie, providing practical moral guidelines in a relatively ‘thick’ content, based on common morality) is frustrated, and, second, principlism makes itself the method of common morality de jure and of moral pluralism de facto.

President Kennedy once said, “Mankind must put an end to war, or war will put an end to mankind.” The purpose of my presentation this evening is to show why a strike against Iraq is dangerous, unjustified, and unnecessary. Since Saddam Hussein has not engaged in any aggressive behavior since the Gulf War, launching an attack would be pre-emptive in nature.

Codex 25 1in the Municipal Library at Porto, Portugal, contains almost exclusively letters ascribed to Saint Jerome. The twelfth-century book mingles letters considered authentically by Jerome with letters doubtfully or wrongly assigned to him. Among the letters in the Porto codex are ten pieces ascribed to Jerome and evidently unpublished. They stand on fols. 101r-104v, 116v-117r and are numbered in the manuscript 151-152, 154-160, and 175.

A number of national educational organizations and individual authors have called for the use of information technology to radically reform higher education. Several projections of how this reformation will unfold are presented here. Three different approaches to critically assessing these projections are considered in this article, two briefly and one in more detail. Brief consideration is given to an approach based on educational values and to an approach based on cost/benefit analysis. After some discussion of the strengths and weaknesses of (...) these approaches, a third approach deriving from a theory of technology control (Incrementalism) is elaborated in more detail and is found to offer helpful criticisms of the called for revolution in higher education. Some recommendations for how these new technologies can be developed in responsible ways are also offered. (shrink)
