24 undergraduates were blindfolded and walked through paths laid out on a floor to investigate whether the orientation of Ss' cognitive maps (CMs) could be determined after they had learned a path by walking through it. Given the assumption that the CM is picturelike, it was predicted that it has a specific orientation, which implies that tests in which the CM is assumed to be aligned with the path should be less difficult than tests in which the CM is hypothesized (...) to be contraligned. In Exp I (8 Ss), Ss were required to draw a picture of the path they had walked through; in Exp II (14 Ss), Ss were required to locate targets in the path under conditions in which their presumed CMs were either aligned or contraligned with the path. Results show that, in Exp I, all Ss drew the 1st line segment of the path upward, suggesting that this part of the path was fixed in an upward direction in memory. In Exp II, Ss were more accurate and faster in locating points on the path when the CM was hypothesized to be aligned with the path than when it was hypothesized to be contraligned. (shrink)

After presenting a paradigm of natural law taken from Cicero and Aquinas, I discuss aspects of Maimonides' ethical theory that appear to conflict with doctrines of natural law. My conclusion will be that Maimonides' adaptation of the Aristotelian metaphysic and doctrine of the "Golden Mean" produced a teleological ethic that is reconcilable with his view that certain moral and legal injunctions are revealed. A doctrine of natural law is compatible with the ethical doctrines that Maimonides held. The thesis I pursue (...) is antithetical to Marvin Fox's (1972:V) contention that "in Judaism there is no natural law doctrine, and in principle there cannot be.". (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.

What do corporations look like when they have integrity, and how can we move more companies in that direction? Corporate Integrity offers a timely, comprehensive framework- and practical business lessons - bringing together questions of organizational design, communication practices, working relationships, and leadership styles to answer this question. Marvin T. Brown explores the five key challenges facing modern businesses as they try to respond ethically to cultural, interpersonal, organizational, civic and environmental challenges. He demonstrates that if corporations are to (...) meet the needs of civil society, they must facilitate inclusive communication patterns based on mutual recognition and civic cooperation. Corporate Integrity is essential reading for professionals in organizational ethics, business leaders, and graduate students looking for practical and reflective insights into doing business with integrity and purpose.

If Savulescu and Kahane’s Principle of Procreative Beneficence were implemented regarding cognitive enhancement, the result would be highly impoverishing for future children. For, apart from being inadequate to rationality itself, advocates’ accounts of cognitive enhancement sever reason from the input to judgments and decision-making that other faculties provide. When handling desire, supporters of cognitive enhancement frame conflicts between reason and the nonrational in terms of self-governance or akratic failure, depending on which one triumphs. Further, so-called negative emotions are treated as (...) simply deleterious and hostile to the rational. Alliances of the nonrational with reason toward shared ends are hence unthinkable. Having critiqued advocates’ views directly, I amplify my assessment through engagement with Aristotle’s Nicomachean Ethics. Per Savulescu and Kahane, to know how to direct enhancement endeavors, “we need to form reasonable opinions on difficult questions about the nature of well-being and the good life.” Thus far, however, enhancement supporters have been largely silent on this crucial matter. Because the debate over enhancement is ultimately over what values our views of flourishing embody, it should be recast so that this crux is squarely at the fore. What is more, for our own and our children’s sakes, as we embark on this reframing, we would do well to bear in mind Aristotle’s insights about the nonrational in relation to reason and his unwavering focus on the human “that for the sake of which” (hou heneka) all that we do is, perforce, undertaken.

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.

How we assess current calls for vigorous, or “radical”, enhancement through befitting procreative choices depends in part on the plausibility of supporters’ rejecting all substantive ties between their views and earlier eugenics. When denying such connections, today’s advocates of vigorous enhancement routinely emphasize that enhancement decisions would stem from individuals and families, not the state. In a multipronged critique, I show the untenability of transhumanists’ denials.

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)

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)

This paper puts forward a novel pluralist theory of epistemic justification that brings together two competing views in the literature—probabilistic and non-probabilistic accounts of justification. The first part of the paper motivates the new theory by arguing that neither probabilistic nor non-probabilistic accounts alone are wholly satisfactory. The second part puts forward what I call the Functional Theory of Justification. The key merit of the new theory is that it combines the most attractive features of both probabilistic and non-probabilistic accounts (...) of justification while avoiding their most serious shortcomings. The paper also provides a blueprint for future pluralist projects in epistemology. (shrink)

I consider the question of what moral obligations prospective parents owe to their future children. It is taken as an almost axiomatic premise of a wide range of philosophical arguments that prospective parents have a moral obligation to take such steps as ensuring their own financial stability or waiting until they are emotionally mature before conceiving. This is because it is assumed that parents have a moral obligation to lay the groundwork for their children's lives to go well. While at (...) first glance such a premise seems benign, I will argue that when it is applied to arguments in assisted reproductive technology, as it is in Julian Savulescu's procreative beneficence argument or as it is in Daniel Groll's recent argument for open gamete donation, we see problems with this premise. Problems in Groll's argument also become apparent when it is scrutinized in connection with this premise. (shrink)

Doctoral programs at U.S. universities play a critical role in the development of human resources both in the United States and abroad. This volume reports the results of an extensive study of U.S. research-doctorate programs in five broad fields: physical sciences and mathematics, engineering, social and behavioral sciences, biological sciences, and the humanities. Research-Doctorate Programs in the United States documents changes that have taken place in the size, structure, and quality of doctoral education since the widely used 1982 editions. This (...) update provides selected information on nearly 4,000 doctoral programs in 41 subdisciplines at 274 doctorate-granting institutions. This volume also reports the results of the National Survey of Graduate Faculty, which polled a sample of faculty for their views on the scholarly quality of program faculty and the effectiveness of doctoral programs in preparing research scholars/scientists. This much-anticipated update of such an essential reference will be useful to education administrators, university faculty, and students seeking authoritative information on doctoral programs.

In many spheres, the law takes the legal concept of causation to correspond to the folk concept (the correspondence assumption). Courts, including the US Supreme Court, tend to insist on the "common understanding" and that which is "natural to say" (Burrage v. United States) when it comes to expressions relating to causation, and frequently refuse to clarify the expression to juries. As recent work in psychology and experimental philosophy has uncovered, lay attributions of causation are susceptible to a great number (...) of unexpected factors, some of which seem rather peripheral to causation. One of those is the norm effect (Knobe & Fraser, 2008): Agents who, in acting as they do, break a salient norm, are more likely to be considered as having caused a certain consequence than when they do not violate a norm. According to some (e.g., Alicke, 1992) this constitutes a bias. According to others (e.g., Sytsma, 2020), the folk concept of causation is sensitive to normative factors, and there’s nothing wrong with that. In this paper, we explore the question whether the norm effect should be considered a bias from the legal perspective on the one hand, and from the psychological perspective on the other. To do this, we test whether norms which are nonpertinent to the consequences or outright silly also impact causation judgements. The data from two preregistered experiments (total N=593) clearly show they do. This, we argue, makes the bias interpretation plausible from the psychological perspective, and both plausible and problematic from the legal perspective. It also shows that the law should abstain from unreflectively assuming conceptual correspondence between legal and ordinary language concepts. (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.

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)

Marx's Rebellion Against Lenin is a representative of the contemporary revitalization of the thought of Marx. It fulfils this task in three ways. First, it overthrows the dialectical materialism of Engels and of Stalinist Bolshevism by exploring 18th century historical thought and illustrating how these Enlightenment historians and political theorists first explored method of historical explanation that were later adopted by Marx. It is shown that contrary to the theory of Stalinist Bolshevism, Hegel was a vital influence on Marx. Second, (...) Levine's book represents Marx as an exponent of Classical Humanism. Marx did not define communism as a form of materialism, as economic egalitarianism, but rather related communism to the Classical ethics of Aristotle, to the Aristotelian ideas of polis citizenship and the ethics of distributive justice. Third, it is argued that the 17th and 18th Century Enlightenment was not simply a liberal center extolling property, individual rights and capitalism. Instead it is shown that the 17th and 18th century Enlightenment was divided between an Enlightenment Center and an Enlightenment Left, with the Enlightenment Left challenging the domination of capitalism and private property. Marx's Rebellion Against Lenin traces the flow of the theories of the Enlightenment Left into Marx and in doing so liberates Marxist thought from its imprisonment in 19th century materialism and relocates it within the traditions of Classical Humanism.
