In various areas of Anglo-American law, legal liability turns on causation. In torts and contracts, we are each liable only for those harms we have caused by the actions that breach our legal duties. Such doctrines explicitly make causation an element of liability. In criminal law, sometimes the causal element for liability is equally explicit, as when a statute makes punishable any act that has “ caused … abuse to the child….” More often, the causal element in criminal liability is (...) more implicit, as when criminal statutes prohibit killings, maimings, rapings, burnings, etc. Such causally complex action verbs are correctly applied only to defendants who have caused death, caused disfigurement, caused penetration, caused fire damage, etc. (shrink)
Freud justified his extensive theorizing about dreams by the observation that they were “the royal road” to something much more general: namely, our unconscious mental life. The current preoccupation with the theory of excuse in criminal law scholarship can be given a similar justification, for the excuses are the royal road to theories of responsibility generally. The thought is that if we understand why we excuse in certain situations but not others, we will have also gained a much more general (...) insight into the nature of responsibility itself. Nowhere has this thought been more evident than in the century-old focus of criminal law theoreticians on the excuse of insanity, a focus that could not be justified by the importance of the excuse itself. In this paper I wish to isolate two theories of excuse, each of which instantiates its own distinctive theory of responsibility. One is what I shall call the choice theory of excuse, according to which one is excused for the doing of a wrongful action because and only because at the moment of such action's performance, one did not have sufficient capacity or opportunity to make the choice to do otherwise. Such a choice theory of excuse instantiates a more general theory of responsibility, according to which we are responsible for wrongs we freely choose to do, and not responsible for wrongs we lacked the freedom to avoid doing. The second I shall call the character theory of excuse, according to which one is excused for the doing of a wrongful action because and only because such action is not determined by those enduring attributes of ourselves we call our characters.

This paper deals with Ludwik Fleck’s theory of thought styles and Michael Polanyi’s theory of tacit knowledge. Though both concepts have been very influential for science studies in general, and both have been subject to numerous interpretations, their accounts have, somewhat surprisingly, hardly been comparatively analyzed. Both Fleck and Polanyi relied on the physiology and psychology of the senses in order to show that scientific knowledge follows less the path of logical principles than the path of accepting or rejecting (...) specific conventions, where these may be psychologically or sociologically grounded. It is my aim to show that similarities and differences between Fleck and Polanyi are to be seen in the specific historical and political context in which they worked. Both authors, I shall argue, emphasized the relevance of perception in close connection to their respective understanding of science, freedom, and democracy. (shrink)
In the Trolley Case, as devised by Philippa Foot and modified by Judith Jarvis Thomson, a runaway trolley is headed down a main track and will hit and kill five unless you divert it onto a side track, where it will hit and kill one.
Michael Walzer is currently at the School of Social Science, Institute for Advanced Study, in Princeton, New Jersey. Professor Walzer has written Just and Unjust Wars; The Revolution of the Saints and has edited Toward A Global Civil Society. In this interview, he discusses some of the current concerns about education, political theory and the current state of the art of toleration, and acceptance and accommodation of different racial, ethnic, social and minority groups. He has published extensively and his (...) work has been translated in several other languages. In this interview, he responds to questions about his work, his writings and his current concerns.

Bart Pattyn: Needless to say, we are more than pleased with the willingness of Michael Walzer to be here in Leuven. After the stimulating lecture yesterday we now have the opportunity to pose some questions to Michael Walzer in the same room where we talked with his friend, Harry Frankfurt, as well as with Bernard Williams. I have asked Professor Selling to moderate this discussion which I am sure he will do with a firm hand.Joseph Selling: We have (...) two papers which Prof. Walzer, and many of you, have read in advance. Perhaps we can take the questions from the authors of those papers and then take other questions. (shrink)
Recent years have seen growing evidence of a fruitful engagement between phenomenology and cognitive science. This paper confronts an in-principle problem that stands in the way of this intellectual coalition, namely the fact that a tension exists between the transcendentalism that characterizes phenomenology and the naturalism that accompanies cognitive science. After articulating the general shape of this tension, I respond as follows. First, I argue that, if we view things through a kind of neo-McDowellian lens, we can open up a (...) conceptual space in which phenomenology and cognitive science may exert productive constraints on each other. Second, I describe some examples of phenomenological cognitive science that illustrate such constraints in action. Third, I use the mutually constraining relationship at work here as the platform from which to bring to light a domesticated version of the transcendental and a minimal form of naturalism that are compatible with each other.

Consequentialists are sometimes accused of being unable to accommodate all the ways in which an agent should care about her own integrity. Here it is helpful to follow Stephen Darwall in distinguishing two approaches to moral theory. First, we might begin with the value of states of affairs and then work our way ‘inward’ to our integrity, explaining the value of the latter in terms of their contribution to the value of the former. This is the ‘outside-in’ approach, and Darwall (...) argues that it is well-suited to defending consequentialism. Alternatively, we might begin with the perspective of a virtuous agent's concern for her integrity, and then work our way ‘outward’, building a conception of the value of states of affairs from this perspective. On this ‘inside-out’ account there is a kind of agent-centred concern each agent should have for her own integrity simply because it is her own. The inside-out approach therefore suggests a possible rationale for a non-consequentialist moral theory, in so far as such a fundamental egocentric concern for one's own integrity seems alien to consequentialism's commitment to the agent-neutrality of value. If this is correct then the consequentialist should explain why we should prefer the outside-in approach to its rival. I argue that the consequentialist can meet this challenge. (shrink)
This paper discusses the problem of gravitational perturbations of radiating spacetimes. We lay out the theoretical framework for describing the interaction of external gravitational fields with a radiating spacetime. This is done by deriving the field perturbation equations for a radiating metric. The equations are then specialized to a Vaidya spacetime. For the Hiscock ansatz of a linear mass model of a radiating blackhole the equations are found separable. Further, the resulting ordinary differential equations are found to admit analytic solutions. (...) We obtain the solutions and discuss their characteristics. (shrink)
The arguments for redistribution of wealth, and for prohibiting certain transactions such as price-gouging, both are based in mistaken conceptions of exchange. This paper proposes a neologism, “euvoluntary” exchange, meaning both that the exchange is truly voluntary and that it benefits both parties to the transaction. The argument has two parts: First, all euvoluntary exchanges should be permitted, and there is no justification for redistribution of wealth if disparities result only from euvoluntary exchanges. Second, even exchanges that are not euvoluntary (...) should generally be permitted, because access to market exchange may be the only means by which people in desperate circumstances can improve their position.

We argue that thoughts are structures of concepts, and that concepts should be individuated by their origins, rather than in terms of their semantic or epistemic properties. Many features of cognition turn on the vehicles of content, thoughts, rather than on the nature of the contents they express. Originalism makes concepts available to explain, with no threat of circularity, puzzling cases concerning thought. In this paper, we mention Hesperus/Phosphorus puzzles, the Evans-Perry example of the ship seen through different windows, and (...) Mates cases, and we believe that there are many additional applications. (shrink)
Consider the following situation. It is the first day of school, and the new third-grade students file into the classroom to be shown to their seats for the coming year. As they enter, the third-grade teacher notices one small boy who is particularly unkempt. He looks to be in desperate need of bathing, and his clothes are dirty, torn and tight-fitting. During recess, the teacher pulls aside the boy's previous teacher and asks about his wretched condition. The other teacher informs (...) her that he always looks that way, even though the boy's family is quite wealthy. The reason he appears as he does, she continues, is that the family observes an odd practice according to which the children do not receive many important things – food, clothing, bathing, even shelter – unless they specifically request them. Since the boy, like many third-graders, has little interest in bathing and clean clothes, he just never asks for them. (shrink)
The idea that immoral behaviour can sometimes be admirable, and that moral behaviour can sometimes be less than admirable, has led several of its supporters to infer that moral considerations are not always overriding, contrary to what has been traditionally maintained. In this paper I shall challenge this inference. My purpose in doing so is to expose and acknowledge something that has been inadequately appreciated, namely, the moral aspect of nonmoral goods and evils. I hope thereby to show that, even (...) if immorality can be admirable, this poses no threat to morality. (shrink)
James Lenman is critical of my claim that moral requirements are requirements of reason. I argue that his criticisms miss their target. More importantly, I argue that the anti-rationalism that informs Lenman's criticisms is itself implausible.
In early 1864, disappointed by the response to his previous work, the young Manchester academic W. Stanley Jevons announced that he was undertaking a study of the so-called coal question: ‘A good publication on the subject would draw a good deal of attention … it is necessary for the present at any rate to write on popular subjects’. When Jevons's The Coal Question was published in April 1865, however, it received comparatively little attention and sales were slow. Jevons and his (...) publisher, Alexander Macmillan, then began sending complimentary copies to luminaries such as Sir John Herschel and Alfred Tennyson. In February 1866 the marketing campaign produced its first substantial return. Macmillan had sent CQ to William Gladstone who responded with letters to both Macmillan and Jevons, noting that the book had strengthened his ‘conviction’ on the necessity for reducing the National Debt. In April, John Stuart Mill praised CQ in the House of Commons, calling for action on the Debt and, three weeks later, as Chancellor of the Exchequer, Gladstone introduced the budget using half his speech to examine the Debt situation and referring to CQ in support for a proposed measure of Debt reduction. With the extensive publicity given to CQ following Mill's speech and the budget, Jevons had achieved his objective in writing the text which went into a second edition in 1866. On the face of it, CQ 's success was due to its effect of introducing a change in budget policy and this is the impression given by some accounts of the episode. (shrink)
I present an original model in judgment aggregation theory that demonstrates the general impossibility of consistently describing decision-making purely at the group level. Only a type of unanimity rule can guarantee a group decision is consistent with supporting reasons, and even this possibility is limited to a small class of reasoning methods. The key innovation is that this result holds when individuals can reason in different ways, an allowance not previously considered in the literature. This generalizes judgment aggregation to subjective (...) decision situations, implying that the discursive dilemma persists without individual agreement on the logical constraints. Notably, the model mirrors the typical method of choosing political representatives, and thus suggests that no voting procedure other than unanimity rule can guarantee representation that reflects electorate opinion. Finally, I apply the results to a normative argument for unanimity rule in contract theory and juries, as well as to problems posed for deliberative democratic theory and the concept of representation.

This article challenges conventional readings of Michel Foucault by examining his fascination with neoliberalism in the late 1970s. Foucault did not critique neoliberalism during this period; rather, he strategically endorsed it. The necessary cause for this approval lies in the broader rehabilitation of economic liberalism in France during the 1970s. The sufficient cause lies in Foucault's own intellectual development: drawing on his long-standing critique of the state as a model for conceptualizing power, Foucault concluded, during the 1970s, that economic liberalism, (...) rather than “discipline,” was modernity's paradigmatic power form. Moreover, this article seeks to clarify the relationship between Foucault's philosophical antihumanism and his assessment of liberalism. Rather than arguing that Foucault's antihumanism precluded a positive appraisal of liberalism, or that the apparent reorientation of his politics in a more liberal direction in the late 1970s entailed a partial retreat from antihumanism, this article contends that Foucault's brief, strategic, and contingent endorsement of liberalism was possible precisely because he saw no incompatibility between antihumanism and liberalism—but only liberalism of the economic variety. Economic liberalism alone, and not its political iteration, was compatible with the philosophical antihumanism that is the hallmark of Foucault's thought. (shrink)
Ambitious and elegant, this book builds a bridge between evolutionary theory and cultural psychology. Michael Tomasello is one of the very few people to have done systematic research on the cognitive capacities of both nonhuman primates and human children. The Cultural Origins of Human Cognition identifies what the differences are, and suggests where they might have come from. -/- Tomasello argues that the roots of the human capacity for symbol-based culture, and the kind of psychological development that takes place (...) within it, are based in a cluster of uniquely human cognitive capacities that emerge early in human ontogeny. These include capacities for sharing attention with other persons; for understanding that others have intentions of their own; and for imitating, not just what someone else does, but what someone else has intended to do. In his discussions of language, symbolic representation, and cognitive development, Tomasello describes with authority and ingenuity the "ratchet effect" of these capacities working over evolutionary and historical time to create the kind of cultural artifacts and settings within which each new generation of children develops. He also proposes a novel hypothesis, based on processes of social cognition and cultural evolution, about what makes the cognitive representations of humans different from those of other primates. -/- Lucid, erudite, and passionate, The Cultural Origins of Human Cognition will be essential reading for developmental psychology, animal behavior, and cultural psychology.
