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)

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.

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.

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.

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)

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.

Glenn Cohen, Holly Fernandez Lynch, and Christopher Deubert are right in their article “A Proposal to Address NFL Club Doctors’ Conflicts of Interest and to Promote Player Trust” that the problem with the medical care rendered to National Football League players is not that the doctors are bad, but that the system in which they provide care is structured badly. We saw some of the problems this system causes last season in what happened to Case Kenum, a quarterback for the (...) Los Angeles Rams who, despite having a possible concussion from a game injury, was allowed to continue to play, with a concussion spotter in the booth and coaches, teammates, seven game officials, and two full training staffs present. From my experience playing in the league from 1989 to 1999, I do not believe that you can eliminate the conflict of interest completely, but I think it can be limited to the point that it does not harm the player. As the structure is now, with the team paying the club doctor, it is impossible to put the players’ health and well-being before the team's on-field priorities. (shrink)

The English Separatist movement provided the background for which John Smyth and Thomas Helwys emerged to reconstitute a biblical ecclesiology. Through the study of the New Testament, they came to the position that infant baptism and covenantal theology could not be the foundation for the New Testament church. Both men embraced believer’s baptism as the basic foundation in which a recovered church should be built. Unfortunately, Smyth defected to the Mennonites, leaving Thomas Helwys to continue the fledging work known as (...) Baptists. This article will examine the life of Thomas Helwys and his contribution to Baptist ecclesiology; it will also review selected literary works that contributed to the recovery of a New Testament church and the founding of Baptist ecclesiology.

This paper investigates the relationship between linguistic expression and human reason in Herder’s Treatise on the Origin of Language. I argue that additive theories of human language, which contend that the linguistic capacity is in principle separable from the other cognitive faculties of the linguistic being, cannot be brought into agreement with Herder’s distinctly transformative account of human language and reason. For Herder, the transformation of our sensible faculties through language is required in order to guarantee the unity of human (...) cognition, and hence reason itself is understood as fundamentally linguistic. This positing of a strong unity between language and reason makes Herder an important, if still under-appreciated, precursor of the twentieth-century linguistic turn. (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)

Proposed here is that an overriding principle of nature governs all population behavior; that a single tenet drives the many regimes observed in nature—exponential-like growth, saturated growth, population decline, population extinction, and oscillatory behavior. The signature of such an all embracing principle is a differential equation which, in a single statement, embraces the entire panoply of observations. In current orthodox theory, this diverse range of population behaviors is described by many different equations—each with its own specific justification. Here, a single (...) equation governing all the regimes is proposed together with the principle from which it derives. The principle is: The effect on the environment of a population’s success is to alter that environment in a way that opposes the success. Experiments are suggested which could validate or refute the theory. Predictions are made about population behaviors. (shrink)

When a handful of people thrive while whole industries implode and millions suffer, it is clear that something is wrong with our economy. The wealth of the few is disconnected from the misery of the many. In Civilizing the Economy, Marvin Brown traces the origin of this economics of dissociation to early capitalism, showing how this is illustrated in Adam Smith's denial of the central role of slavery in wealth creation. In place of the Smithian economics of property, Brown (...) proposes that we turn to the original meaning of economics as household management. He presents a new framework for the global economy that reframes its purpose as the making of provisions instead of the accumulation of property. This bold new vision establishes the civic sphere as the platform for organizing an inclusive economy and as a way to move toward a more just and sustainable world. (shrink)

This paper approaches the question of corporate integrity and leadership from a civic perspective, which means that corporations are seen as members of civil society, corporate members are seen as citizens, and corporate decisions are guided by civic norms. Corporate integrity, from this perspective, requires that the communication patterns that constitute interpersonal relationships at work exhibit the civic norm of reciprocity and acknowledge the need for security and the right to participate. Since leaders are members of corporate relationships, their integrity (...) will be determined by the integrity of these interpersonal relationships, and by their efforts to improve them. (shrink)

This article advances the view that propositional logic can and should be taught within general education logic courses in ways that emphasizes its practical usefulness, much beyond what commonly occurs in logic textbooks. Discussion and examples of this relevance include database searching, understanding structured documents, and integrating concepts of proof construction with argument analysis. The underlying rationale for this approach is shown to have import for questions concerning the design of logic courses, textbooks, and the general education curriculum, particularly the (...) sequencing of formal and informal logic courses.
