In an article “Countering a Counter-intuitive Probability” [4], Lynn E. Rose discusses a question in conditional probability, claiming that the following problem posed by Copi [1] is usually incorrectly solved:Remove all cards except aces and kings from a deck, so that only eight cards remain, of which four are aces and four are kings. From this abbreviated deck, deal two cards to a friend. If he looks at his cards and announces that his hand contains an ace, what is (...) the probability that both his cards are aces? If he announces instead that one of his cards is the ace of spades, what is the probability then that both his cards are aces? (shrink)

Three eminent scientists analyze the scientific, social, and political roots of biological determinism.

When we consider some controversies among scholars about whether brainstem death is death, we should clearly identify what the controversy is about. Is it about whether the brainstem dead can be ca...

How do communities establish shared communication systems? The Common Knowledge view assumes that symbolic conventions develop through the accumulation of common knowledge regarding communication practices among the members of a community. In contrast with this view, it is proposed that coordinated communication emerges a by‐product of local interactions among dyads. A set of multi‐agent computer simulations show that a population of “egocentric” agents can establish and maintain symbolic conventions without common knowledge. In the simulations, convergence to a single conventional system (...) was most likely and most efficient when agents updated their behavior on the basis of local rather than global, system‐level information. The massive feedback and parallelism present in the simulations gave rise to phenomena that are often assumed to result from complex strategic processing on the part of individual agents. The implications of these findings for the development of theories of language use are discussed. (shrink)

Dale Dorsey considers one of the most fundamental questions in philosophical ethics: to what extent do the demands of morality have normative authority over us and our lives? Must we conform to moral requirements? Most who have addressed this question have treated the normative significance of morality as simply a fact to be explained. But Dorsey argues that this traditional assumption is misguided. According to Dorsey, not only are we not required to conform to moral demands, conforming to morality's (...) demands will not always even be normatively permissible---moral behavior can be wrong. This view is significant not only for understanding the content and force of the moral point of view, but also for understanding the basic elements of how one ought to live. (shrink)

A feminist study of language and its rules argues that men have shaped it in order to instill their own prejudices and viewpoints on society, and shows how male-slanted language affects all women's lives.

Biological individuality is a notoriously thorny topic for biologists and philosophers of biology. In this paper we argue that biological individuality presents multiple, interconnected questions for biologists and philosophers that together form a problem agenda. Using a case study of an interdisciplinary research group in ecology, behavioral and evolutionary biology, we claim that a debate on biological individuality that seeks to account for diverse practices in the biological sciences should be broadened to include and give prominence to questions about uniqueness (...) and temporality. We show that broadening the problem agenda of biological individuality draws attention to underrecognized philosophical issues and discussions and thereby organizes and enriches the existing debate.

Much of knowing what to do is knowing what to do for ourselves, but knowing how to act in our best interest is complex---we must know what benefits us, what burdens us, and how these facts present and constitute considerations in favor of action. Additionally, we must know how we should weigh our interests at different times---past, present, and future. Dale Dorsey argues that a theory of prudence is needed: a theory of how we ought to act when we (...) are acting for ourselves. A Theory of Prudence provides a comprehensive account of prudence, including the metaethics of prudential value, the nature of the personal good, the reasons of prudence, and the structure of prudential normativity over time.

The emergence of controlled, Maastricht Category III, non-heart-beating organ donation programs has the potential to greatly increase the supply of donor solid organs by increasing the number of potential donors. Category III donation involves unconscious and dying intensive care patients whose organs become available for transplant after life-sustaining treatments are withdrawn, usually on grounds of futility. The shortfall in organs from heart-beating organ donation following brain death has prompted a surge of interest in NHBD. In a recent editorial, the British (...) Medical Journal described NHBD as representing “a challenge which the medical profession has to take up.”. (shrink)

The shape of a life hypothesis holds, very roughly, that lives are better when they have an upward, rather than downward, slope in terms of momentary well-being. This hypothesis is plausible and has been thought to cause problems for traditional principles of prudential value/rationality. In this article, I conduct an inquiry into the shape of a life hypothesis that addresses two crucial questions. The first question is: what is the most plausible underlying explanation of the significance of a life’s shape? (...) The second question is: given its most plausible explanation, what does the shape of a life hypothesis teach us about the nature of prudential value? (shrink)

Subjectivism about well-being holds that ϕ is intrinsically good for x if and only if, and to the extent that, ϕ is valued, under the proper conditions, by x. Given this statement of the view, there is room for intramural dissent among subjectivists. One important source of dispute is the phrase “under the proper conditions”: Should the proper conditions of valuing be actual or idealized? What sort of idealization is appropriate? And so forth. Though these concerns are of the first (...) importance, this essay focuses on a second source of dispute. As stated, subjectivists must account for what it means for an individual x to value ϕ under any conditions. Though there has been some disagreement, most subjectivists hold that x values ϕ if and only if x desires ϕ. This essay argues that subjectivists have erred in accepting a desiderative theory of valuing. Instead, it argues that subjectivists should hold that x values ϕ to the extent that x judges or believes that ϕ is good for x. The resulting “judgment subjectivism” is intuitively superior to, and maintains important structural advantages over, its desiderative rival. (shrink)

Many find it plausible to posit a category of supererogatory actions. But the supererogatory resists easy analysis. Traditionally, supererogatory actions are characterized as actions that are morally good, but not morally required; actions that go the call of our moral obligations. As I shall argue in this article, however, the traditional analysis can be accepted only by a view with troubling consequences concerning the structure of the moral point of view. I propose a different analysis that is extensionally correct, avoids (...) the problems of the traditional view, and, incidentally, also defuses any objection to act-consequentialism, or any other first-order moral theory, on grounds that it cannot accommodate the supererogatory.

Welfare is at least occasionally a temporal phenomenon: welfare benefits befall me at certain times. But this fact seems to present a problem for a desire-satisfaction view. Assume that I desire, at 10am, January 12th, 2010, to climb Mount Everest sometime during 2012. Also assume, however, that during 2011, my desires undergo a shift: I no longer desire to climb Mount Everest during 2012. In fact, I develop an aversion to so doing. Imagine, however, that despite my aversion, I am (...) forced to climb Mount Everest. Does climbing Mount Everest benefit me? If so, when? A natural answer seems to be that if in fact it does benefit me, it benefits me at no particular time, and hence the desire-satisfaction view cannot accommodate the phenomenon of temporal welfare. In this paper, I argue, first, that a desire-satisfaction view can accommodate the phenomenon of temporal welfare only by accepting what I call the “time-of-desire” view: that p benefits x at t only if x desires p at t . Second, I argue that this view can be defended from important objections. (shrink)

A compact complex space X is viewed as a 1-st order structure by taking predicates for analytic subsets of X, X \times X, … as basic relations. Let f: X→ Y be a proper surjective holomorphic map between complex spaces and set Xy:=f-1(y). We show that the set Ak,d:={y∈ Y: the number of d-dimensional components of Xy is (...) holomorphic map. The analogous result in the context of algebraic geometry gives rise to the definability of Morley degree. (shrink)

This book is the first to engage Zen Buddhism philosophically on crucial issues from a perspective that is informed by the traditions of western philosophy and religion. It focuses on one renowned Zen master, Huang Po, whose recorded sayings exemplify the spirit of the 'golden age' of Zen in medieval China, and on the transmission of these writings to the West. The author makes a bold attempt to articulate a post-romantic understanding of Zen applicable to contemporary world culture. While deeply (...) sympathetic to the Zen tradition, he raises serious questions about the kinds of claims that can be made on its behalf. (shrink)

One important proposal about the nature of well-being, prudential value or the personal good is that intrinsic values for a person ought to ‘resonate’ with the person for whom they are good. Indeed, virtually everyone agrees that there is something very plausible about this necessary condition on the building blocks of a good life. Given the importance of this constraint, however, it may come as something of a surprise how little reason we actually have to believe it. In this paper, (...) I'd like to do two things: first, to illustrate just how philosophically tenuous this thesis is, despite its apparent attraction, and to correct, or at least begin to correct, this state of affairs. My argument—which I call the ‘relationship to value’ argument—focuses in part on what it means to be a valuer—specifically, the peculiar relationship valuing agents bear to objects of value.

An important platitude about prudential rationality is that I should not refuse to sacrifice a smaller amount of present welfare for the sake of larger future benefits. I ought, in other words, to treat my present and future as of equal prudential significance. The demands of prudence are less clear, however, when it comes to one’s past selves. In this paper, I argue that past benefits are possible in two ways, and that this fact cannot be easily accommodated by traditional (...) approaches to prudential rationality. Against univocal accounts of prudential rationality, I hold that the possibility of past benefits suggests that a bias toward the present and future is defensible when it comes to some welfare goods, but that prudential reasons are temporally neutral between when it comes to the success or failure of one’s long-term projects.

Perfectionism, or the claim that human well-being consists in the development and exercise of one’s natural or essential capacities, is in growth mode. With its long and distinguished historical pedigree, perfectionism has emerged as a powerful antedote to what are perceived as significant problems in desiderative and hedonist accounts of well-being. However, perfectionism is one among many views that deny the influence of our desires, or that cut the link between well-being and a raw appeal to sensory pleasure. Other views (...) include, for instance, the “objective list” view,1 the so-called “restricted achievement” view,2 and various hybrid views that combine an appeal to desire or pleasure with an objective standard of evaluation of those desires or pleasures.

University of Alberta Forthcoming in Utilias Consider Lives for Headaches: there is some number of headaches such that the relief of those headaches is sufficient to outweigh the good life of an innocent person. Lives for Headaches is unintuitive, but difficult to deny. The argument leading to Lives for Headaches is valid, and appears to be constructed out of firmly entrenched premises. In this paper, I advocate one way to reject Lives for Headaches; I defend a form of lexical superiority (...) between values. Based on an inquiry into the notion of human well-being, I argue that no amount of headaches is sufficient to outweigh the disvalue of the loss of a good life. Though this view has been thought subject to devastating objections, these objections are not dispositive against the form of value superiority I advance here. (shrink)

In 1963 Niko Tinbergen published a paper, "On Aims and Methods of Ethology," dedicated to his friend Konrad Lorenz. Here Tinbergen defines ethology as "the biological study of behavior," and seeks to demonstrate "the close affinity between Ethology and the rest of Biology." Tinbergen identifies four major areas of ethology: causation, survival value, evolution, and ontogeny. Our goal is to attempt for cognitive ethology what Tinbergen succeeded in doing for ethology: to clarify its aims and methods, to distinguish some of (...) its varieties, and to defend the fruitfulness of the research strategies that it has spawned.

This comprehensive, general introduction to Schelling's philosophy shows that it was Schelling who set the agenda for German idealism and defined the term of its characteristic problems.

In this paper I develop a concept of behavioural ecological individuality. Using findings from a case study which employed qualitative methods, I argue that individuality in behavioural ecology should be defined as phenotypic and ecological uniqueness, a concept that is operationalised in terms of individual differences such as animal personality and individual specialisation. This account make sense of how the term “individuality” is used in relation to intrapopulation variation in behavioural ecology. The concept of behavioural ecological individuality can sometimes be (...) used to identify individuals. It also shapes research agendas and methodological choices in behavioural ecology, leading researchers to account for individuals as sources of variation. Overall, this paper draws attention to a field that has been largely overlooked in philosophical discussions of biological individuality and highlights the importance of individual differences and uniqueness for individuality in behavioural ecology.

A structure which generalizes formulas by including substitution terms is used to represent proofs in classical logic. These structures, called expansion trees, can be most easily understood as describing a tautologous substitution instance of a theorem. They also provide a computationally useful representation of classical proofs as first-class values. As values they are compact and can easily be manipulated and transformed. For example, we present an explicit transformations between expansion tree proofs and cut-free sequential proofs. A theorem prover which represents (...) proofs using expansion trees can use this transformation to present its proofs in more human-readable form. Also a very simple computation on expansion trees can transform them into Craig-style linear reasoning and into interpolants when they exist. We have chosen a sublogic of the Simple Theory of Types for our classical logic because it elegantly represents substitutions at all finite types through the use of the typed -calculus. Since all the proof-theoretic results we shall study depend heavily on properties of substitutions, using this logic has allowed us to strengthen and extend prior results: we are able to prove a strengthen form of the firstorder interpolation theorem as well as provide a correct description of Skolem functions and the Herbrand Universe. The latter are not straightforward generalization of their first-order definitions. (shrink)

As a result of these restrictions, an implementation of L [subscript lambda] does not need to implement full higher-order unification. Instead, an extension to first-order unification that respects bound variable names and scopes is all that is required. Such unification problems are shown to be decidable and to possess most general unifiers when unifiers exist. A unification algorithm and logic programming interpreter are described and proved correct. Several examples of using L[subscript lambda] as a meta-programming language are presented.

An important constraint on the nature of intrinsic value---the “Supervenience Principle” (SP)---holds that some object, event, or state of affairs ϕ is intrinsically valuable only if the value of ϕ supervenes entirely on ϕ 's intrinsic properties. In this paper, I argue that SP should be rejected. SP is inordinately restrictive. In particular, I argue that no SP-respecting conception of intrinsic value can accept the importance of psychological resonance, or the positive endorsement of persons, in explaining value.

After critiquing some earlier attempts (including those of Marcus Singer and Frances Howard–Snyder) to ground objections to actual–consequence act utilitarianism (ACAU) on human cognitive limitations, I present two new objections with this same foundation. Both start with the observation that, because human cognitive abilities are not up to the task of reliably recognizing utility–maximizing actions, any agents who are recognizably human – including the best possible humans, morally speaking – are certain to perform many actions every day that ACAU says (...) are immoral, and to perform some actions over the course of their lives that it says are highly immoral. The first objection is that, if Mill's analysis of what it means to call an action wrong is accurate, then ACAU entails a conclusion that no one will accept, viz., that the morally–best humans possible ought to undergo constant punishment. The second objection is that ACAU entails that even the morally–best humans possible are bad moral agents in some respect. This conclusion, while unpalatable, is not so obviously unacceptable as the first. However, I do briefly consider some ways in which it might be possible to demonstrate that it is false and thereby complete a reductio of ACAU. (shrink)

Argument-giving reasons for a view-is our model of rational dispute resolution. Fogelin suggests that certain "deep" disagreements cannot be resolved in this way because features of their context "undercut the conditions essential to arguing" . In this paper we add some detail to Fogelin's treatment of intractable disagreements. In doing so we distinguish between his relatively modest claim that some disputes cannot be resolved through argument and his more radical claim that such disputes are beyond rational resolution. This distinction, along (...) with some ofthe detail we add to Fogelin's treatment, sheds some useful light on the project of informal logic. (shrink)

ABSTRACTWhen faced with hardship, how do we emotionally appraise the situation? Although many factors contribute to our reasoning about hardships, in this article we focus on the role of linguistic metaphor in shaping how we cope. In five experiments, we find that framing a person’s cancer situation as a “battle” encourages people to believe that that person is more likely to feel guilty if they do not recover than framing the same situation as a “journey” does. Conversely, the “journey” frame (...) is more likely to encourage the inference that the person can make peace with their situation than the “battle” frame. We rule out lexical priming as an explanation for this effect and examine the generalizability of these findings to individual differences across participants and to a different type of hardship—namely, an experience with depression. Finally, we examine the language participants produced after encountering one of these metaphors, and we find tendencies to repeat and extend the metaphors encountered.... (shrink)

A wealth of evidence supports the idea that the circuitry of the developing nervous system is gradually elaborated under the instructive influence of neural activity. Some care must be taken, however, not to handicap the acceptance of this useful perspective with too onerous a theoretical superstructure.

Based on electrophysiological and anatomical studies, a prevalent conception is that the visual system recovers features of the world from retinal images to generate perceptions and guide behavior. This paradigm, however, is unable to explain why visual perceptions differ from physical measurements, or how behavior could routinely succeed on this basis. An alternative is that vision does not recover features of the world, but assigns perceptual qualities empirically by associating frequently occurring stimulus patterns with useful responses on the basis of (...) survival and reproductive success. The purpose of the present article is to briefly describe this strategy of vision and the evidence for it. (shrink)
