In this paper, we show that Case-based decision theory, proposed by Gilboa and Schmeidler :605–639, 1995), can explain the aggregate dynamics of cooperation in the repeated Prisoner’s Dilemma, as observed in the experiments performed by Camera and Casari. Moreover, we find CBDT provides a better fit to the dynamics of cooperation than does the existing Probit model, which is the first time such a result has been found. We also find that humans aspire to a payoff above the mutual defection (...) outcome but below the mutual cooperation outcome, which suggests they hope, but are not confident, that cooperation can be achieved. Finally, our best-fitting parameters suggest that circumstances with more details are easier to recall. We make a prediction for future experiments: if the repeated PD were run for more periods, then we would be begin to see an increase in cooperation, most dramatically in the second treatment, where history is observed but identities are not. This is the first application of Case-based decision theory to a strategic context and the first empirical test of CBDT in such a context. It is also the first application of bootstrapped standard errors to an agent-based model. (shrink)

As Christians, we are called to think about the fundamental values that shape and guide our economic behavior and the economic structures of our society. This article focuses on the ways in which the problem of predatory lending, or usury, allows us to examine our most basic Christian values and principles and think about how they might serve as a moral foundation for reshaping our economic structures and transactions.

This paper argues that conceptualizing unity as "interconnection" (rather than reduction) provides a more fruitful and versatile framework for the philosophical study of scientific unification. Building on the work of Darden and Maull, Kitcher, and Kincaid, I treat unity as a relationship between fields: two fields become more integrated as the number and/or significance of interfield connections grow. Even when reduction fails, two theories or fields can be unified (integrated) in significant ways. I highlight two largely independent dimensions of unification. (...) Fields are theoretically unified to the extent that we understand how the ontologies, concepts, and generalizations of these fields are connected. (Reductionism is one form of theoretical unity, but not the only form). Fields are practically unified through heuristic connections (e.g., using the heuristics of one field to generate hypotheses in another field) and by the development of methods for integrating the qualitatively distinct bodies of data generated by the two fields. I discuss the relationship between paleontological and neontological systematics to illustrate the utility of conceptualizing unity as interconnection. (shrink)

In this article I examine the status of putative aesthetic judgements in science and mathematics. I argue that if the judgements at issue are taken to be genuinely aesthetic they can be divided into two types, positing either a disjunction or connection between aesthetic and epistemic criteria in theory/proof assessment. I show that both types of claim face serious difficulties in explaining the purported role of aesthetic judgements in these areas. I claim that the best current explanation of this role, (...) McAllister's 'aesthetic induction' model, fails to demonstrate that the judgements at issue are genuinely aesthetic. I argue that, in light of these considerations, there are strong reasons for suspecting that many, and perhaps all, of the supposedly aesthetic claims are not genuinely aesthetic but are in fact 'masked' epistemic assessments.

This paper is a defense of "explanatory pluralism" (i.e., the view that some events can be correctly explained in two distinct ways). To defend pluralism, I identify two distinct (but compatible) styles of explanation in paleobiology. The first approach ("actual sequence explanation") traces out the particular forces that affect each species. The second approach treats the trend as "passive" or "random" diffusion away from a boundary in morphological space. I argue that while these strategies are distinct, some trends are correctly (...) explained in both ways. Further, since neither strategy can be reduced or eliminated from paleobiology, we should accept that both strategies can provide correct explanations for a single trend. (shrink)

An exploration of the important philosophical issues and concerns related to artificial intelligence. The book focuses on the philosphical, rather than the technical or technological aspects of artificial intelligence.

This volume considers formalisations of love in the 21st century. Engaging with the Slovenian School of Philosophy, the book contends that psychoanalysis is the one line of thought that exposes the role that love plays in all knowledge, emphasising the importance of love in these unsettled times.

Scholars are divided as to whether reduction should be a central strategy for understanding the world. While reductive analysis is the standard mode of explanation in many areas of science and everyday life, many consider reductionism a sign of “intellectual naivete and backwardness.” In this paper I make three points about the proper status of anti-reductionism: First, reduction, is, in fact, a centrally important epistemic strategy. Second, reduction to physics is always possible for all causal properties. Third, there are, nevertheless, (...) reasons we want science to discover properties and explanations other than reductive physical ones. (shrink)

A broad evolutionary perspective is essential to fully reverse figure and ground in the rationality debate. Humans' evolved psychological architecture was designed to produce inferences that were adaptive, not normatively logical. This perspective points to several predictable sources of errors in modern laboratory reasoning tasks, including inherent, systematic biases in information-processing systems explained by Error Management Theory.

We examine the impact of a unilateral carbon tax in developed countries, focusing on the expected size of carbon leakage and the effects on leakage of border tax adjustments. We start by analyzing the problem using a simple two-country, three-good general equilibrium model to develop intuitions. We then simulate the expected size of the effects using a new, open-source, computable general equilibrium model. We analyze the extent of emissions reductions from a carbon tax in countries that made commitments under the (...) Kyoto Protocol, the expected carbon leakage, and the effects of border tax adjustments on carbon leakage, all relative to our baseline projections for emissions. We also perform extensive sensitivity tests on the parameters of the CGE model. Finally, we consider the effects of imperfect border tax adjustments on leakage, such as global or regional schedules of border taxes. (shrink)

Gould's Structure ofEvolutionary Theory argues that Darwinism hasundergone significant revision. Although Gouldsucceeds in showing that hierarchicalapproaches have expanded Darwinism, hiscritique of adaptationism is less successful. Gould claims that the ubiquity of developmentalconstraints and spandrels has forced biologiststo soften their commitment to adaptationism. Iargue that Gould overstates his conclusion; hisprincipal claims are compatible with at leastsome versions of adaptationism. Despite thisweakness, Gould's discussion of adaptationism –particularly his discussions of the exaptivepool and cross-level spandrels – shouldprovoke new work in evolutionary theory and (...) thephilosophy of biology.

This article presents three experiments that examine the relation between order effects and frequency learning, with the following results. First, when frequencies of occurrence are presented as sequences of real events, base rates can be learned and used with a high degree of accuracy. However, conditional probabilities for multiple sequentially presented evidence items cannot be completely learned, due to the distortion of a recency order effect for actual decisions. Second, there is also a recency order effect for belief evaluations, which (...) cannot be eliminated even if base rates are used correctly. Third, base rates learned in one environment can be transferred to another environment, but the transfer soon diminishes due to learning in the new environment. However, belief evaluations are not transferred from one environment to another The existing models of frequency learning cannot explain the order effect for actual decisions because they do not consider sequential information. The existing models of belief updating can explain both types of order effects, but they do not have any mechanisms for frequency learning. To account for the complete spectrum of frequency learning and order effects, we outline our initial effort in developing a unified model that integrates frequency learning and order effects.

For Reid, sensations do not enter into the analysis of perception proper. Instead they “intervene” between the effects of bodily qualities on our sense organs and our perception of those qualities (Inq VI xxi, 174).1 The question addressed in this essay is: What sort of thing does Reid take this interloper to be?2 The answer defended is that sensations are reflexive mental acts, i.e., acts which take themselves as objects.

There are a vast number of ways of explaining human behavior in the social sciences and in ordinary conversation. One family of accounts seeks to explain behavior using terms such as norms, customs, tradition, convention , and culture . Despite the ubiquity of these terms, it is not fully clear how these concepts really explain behavior, how they are related, how they differ, and what they contrast with. In this article, I hope to answer such questions. Key Words: norm • (...) custom • convention • explanation. (shrink)

Phillips & Silverstein argue that a range of cognitive disturbances in schizophrenia result from a deficit in cognitive coordination attributable to NMDA receptor dysfunction. We suggest that the viability of this hypothesis would be further supported by explicit implementation in a computational framework that can produce quantitative estimates of the behavior of both healthy individuals and individuals with schizophrenia.

Blair proposes that fluid intelligence, working memory, and executive function form a unitary construct: fluid cognition. Recently, our group has utilized a combined correlational–experimental cognitive neuroscience approach, which we argue is beneficial for investigating relationships among these individual differences in terms of neural mechanisms underlying them. Our data do not completely support Blair's strong position. (Published Online April 5 2006).

Schmitt recognized that research is needed to identify other factors associated with sex ratio and with sociosexuality that may explain cross-cultural variation in sexual behavior. One such factor may be the risk of sperm competition. Sperm competition theory may lead us to a more complete explanation of cultural variation in sexual behavior.

This paper examines the moral significance of guilt in the context of how students confront the suffering of another. Within social-justice education, such confrontations are often staged in pedagogical efforts to encourage students to assume social responsibility. Frequently, however, the guilt that students claim to endure as a result of these pedagogical encounters is not perceived to be of much ethical import. By exploring the psychoanalytic work of Melanie Klein and the ethical philosophy of Emmanuel Levinas, this essay argues that (...) guilt arises out of our susceptibility to another’s pain and that it plays a crucial role both in ‘making reparation’ (Klein) and in the very formation of responsibility itself (Levinas).

This paper explores the connections between Kant’s theory of hierarchical racial difference, on the one hand, and his cosmopolitanism and conceptions of moral and political progress, on the other. I argue that Kant’s racial biology plays an essential role in maintaining national-cultural differences, which he views as essential for the establishment of the cosmopolitan union. Unfortunately, not only are these views racist, they also complicate Kant’s ability to consistently think through the prospect of the human species’ moral progress. Thus, while (...) in the abstract, Kant’s attempts to understand the prospects for moral and political progress as rooted in historical reality, and his insistence that such progress is necessarily connected to the persistence of cultural difference, is appealing, his own way of carrying this out is decidedly not, being so intimately connected to racial hierarchy as a basic source of difference.

In a recent paper, Patrick Todd and Brian Rabern argued that—contra both Thomason's supervaluationism and MacFarlane's relativism—an “open future” view is incompatible with the principle they call “Retro‐closure”, according to which today's rain implies that yesterday it was true that it would rain a day later. In a recent piece, MacFarlane replies. This paper has two aims. First, I argue that MacFarlane's response to Todd and Rabern is unsuccessful on its own terms. Second, I attempt to clarify (...) class='Hi'>Todd and Rabern's overall argument, and explain how MacFarlane's replies should be construed within the overall dialectic. The intended result: if you want an “open future”, then one's best option is a modified Peirceanism (as in Todd, The Open Future); if one wants Retro‐closure, one's best option is one on which there is a determinate “Thin Red Line” (a view sometimes called “Ockhamism”). However, one cannot have what supervaluationism and relativism both promise, viz., a view that preserves both. (shrink)

Connexins were first identified in the 1970s as the molecular components of vertebrate gap junctions. Since then a large literature has accumulated on the cell and molecular biology of this multi‐gene family culminating recently in the findings that connexin mutations are implicated in a variety of human diseases. Over two decades, the terms “connexin” and “gap junction” had become almost synonymous. In the last few years a second family of gap‐junction genes, the innexins, has emerged. These have been shown to (...) form intercellular channels in genetically tractable invertebrate organisms such as Drosophila melanogaster and Caenorhabditis elegans. The completed genomic sequences for the fly and worm allow identification of the full complement of innexin genes in these two organisms and provide valuable resources for genetic analyses of gap junction function.

Proposed models of closed timelike curves have been shown to enable powerful information-processing protocols. We examine the simulation of models of CTCs both by other models of CTCs and by physical systems without access to CTCs. We prove that the recently proposed transition probability CTCs are physically equivalent to postselection CTCs, in the sense that one model can simulate the other with reasonable overhead. As a consequence, their information-processing capabilities are equivalent. We also describe a method for quantum computers to (...) simulate Deutschian CTCs. In cases for which the overhead is reasonable, it might be possible to perform the simulation in a table-top experiment. This approach has the benefit of resolving some ambiguities associated with the equivalent circuit model of Ralph et al. Furthermore, we provide an explicit form for the state of the CTC system such that it is a maximum-entropy state, as prescribed by Deutsch. (shrink)

Polls suggest up to twenty percent of Americans describe their beliefs as 'libertarian', but libertarians are often derided as heartless Social Darwinists or naïve idealists. This illuminating handbook brings together scholars from a range of fields and political perspectives to consider how classical liberal principles can help us understand and potentially address a variety of pressing social problems including immigration, climate change, the growth of the prison population, and a host of others. Anyone interested in political theory or practical law (...) and politics will find this book an essential resource for understanding this major strand of American politics. (shrink)

It is suggested that there is a strong connection between intentions and plans, and these plans are then taken to be programs of the sort suggested by Miller, Galanter, and Pribram in Plans and the Structure of Behavior. There is then a hierarchy of programs connected with intentions stretching from the macroscopic level of ordinary discourse to the neurological level. It is argued that as we proceed downwards we arrive at a threshold below which we can still describe the phenomena (...) but below which we can no longer speak of intentions. The paper concludes with a discussion of the criteria for the identity of intentions at various levels. (shrink)

This paper explores the context of environmental justice (EJ) in Scotland, and presents a case study whereby the main attributes for an indicator of EJ were identified, encompassing procedural and distributive aspects of justice. Through a participatory process, weights were assigned using a Multi-Criteria Analysis tool, the Analytical Hierarchy Process (AHP). Results show that overall, environmental injustices are mostly associated by respondents to unequal distribution of health burdens due to pollution, yet greater weight is attached to procedural justice by community (...) environmental activists. The paper suggests that AHP may be applied to many situations and could form a basis for the development of tools to address and deliver EJ in Scotland. (shrink)

This article seeks to provide a fuller account of the philosophy of religion of the Marburg Neo-Kantian, Paul Natorp (1854–1924), than has hitherto been available. It does so by describing important changes in Natorp’s thinking about religion between the publication of his early book, Religion innerhalb der Grenzen der Humanität (1894), and later writings in which he espouses a version of logos-mysticism strikingly at odds with the concept of a “religion of reason” put forward by his long-time Marburg colleague, Hermann (...) Cohen (1842–1918). These differences are analyzed in relation to these two thinkers’ divergent views on philosophical systematics, and their respective experiences of the First World War. (shrink)

In this new contribution to moral theory, Todd Lekan argues for a pragmatist conception of morality as an evolving, educational, and fallible practice of everyday life. Drawing on the work of John Dewey, Lekan asserts that moral norms are neither timeless truths nor subjective whims, but habits transmitted through practices. Like the habits that make up medicine or engineering, moral habits are subject to rational evaluation and change according to new challenges and circumstances.

I answer Alvin Plantinga's challenge to provide a ‘proper’ de jure objection to religious belief. What I call the ‘sophisticates’ evidential objection' concludes that sophisticated Christians lack epistemic justification for believing central Christian propositions. The SEO utilizes a theory of epistemic justification in the spirit of the evidentialism of Richard Feldman and Earl Conee. I defend philosophical interest in the SEO against objections from Reformed epistemology, by addressing Plantinga's criteria for a proper de jure objection, his anti-evidentialist arguments, and the (...) relevance of ‘impulsional evidence’. I argue that no result from Plantinga-style Reformed epistemology precludes the reasons I offer in favour of giving the SEO its due philosophical attention. (shrink)

In The Democracy of Suffering philosopher Todd Dufresne provides a strikingly original exploration of the past, present, and future of this epoch, the Anthropocene, demonstrating how the twin crises of reason and capital have dramatically remade the essential conditions for life itself. Images, cartoons, artworks, and quotes pulled from literary and popular culture supplement this engaging and unorthodox look into where we stand amidst the ravages of climate change and capitalist economics. With humour, passion, and erudition, Dufresne diagnoses a (...) frightening new reality and proposes a way forward, arguing that our serial experiences of catastrophic climate change herald an intellectual and moral awakening - one that lays the groundwork, albeit at the last possible moment, for a future beyond individualism, hate, and greed. That future is unapologetically collective. It begins with a shift in human consciousness, with philosophy in its broadest sense, and extends to a reengagement with our greatest ideals of economic, social, and political justice for all. But this collective future, Dufresne argues, is either now or never. Uncovering how we got into this mess and how, if at all, we get out of it, The Democracy of Suffering is a flicker of light, or perhaps a scream, in the face of human extinction and the end of civilization.

Recently, philosophers have turned their attention to the question, not when a given agent is blameworthy for what she does, but when a further agent has the moral standing to blame her for what she does. Philosophers have proposed at least four conditions on having “moral standing”: -/- 1. One’s blame would not be “hypocritical”. 2. One is not oneself “involved in” the target agent’s wrongdoing. 3. One must be warranted in believing that the target is indeed blameworthy for the (...) wrongdoing. 4. The target’s wrongdoing must some of “one’s business”. -/- These conditions are often proposed as both conditions on one and the same thing, and as marking fundamentally different ways of “losing standing.” Here I call these claims into question. First, I claim that conditions (3) and (4) are simply conditions on different things than are conditions (1) and (2). Second, I argue that condition (2) reduces to condition (1): when “involvement” removes someone’s standing to blame, it does so only by indicating something further about that agent, viz., that he or she lacks commitment to the values that condemn the wrongdoer’s action. The result: after we clarify the nature of the non-hypocrisy condition, we will have a unified account of moral standing to blame. Issues also discussed: whether standing can ever be regained, the relationship between standing and our "moral fragility", the difference between mere inconsistency and hypocrisy, and whether a condition of standing might be derived from deeper facts about the "equality of persons".

This Introduction has three sections, on "logical fatalism," "theological fatalism," and the problem of future contingents, respectively. In the first two sections, we focus on the crucial idea of "dependence" and the role it plays it fatalistic arguments. Arguably, the primary response to the problems of logical and theological fatalism invokes the claim that the relevant past truths or divine beliefs depend on what we do, and therefore needn't be held fixed when evaluating what we can do. We call the (...) sort of dependence needed for this response to be successful "dependence with a capital 'd'": Dependence. We consider different accounts of Dependence, especially the account implicit in the so-called "Ockhamist" response to the fatalistic arguments. Finally, we present the problem of future contingents: what could "ground" truths about the undetermined future? On the other hand, how could all such propositions fail to be true? (shrink)

In this paper, we summarize the various impacts of incarceration with the aim of providing an overview of the ways mass incarceration affects society. In doing so, we look inside the black box of the largest penal experiment in world history: the quintupling of the prison population in the United States between 1973 and 2006. The question is, "What have been the social consequences of our incarceration policy?"One objective is to provide insight into what might be called the prison policy (...) paradox, namely, that a 500% generation_long growth in imprisonment has had little impact on crime. Answers are provided by looking inside the black box of penal policy and by identifying the various ways incarceration leads to social outcomes that are associated with public safety. The paper considers the problem of "public safety," because safety is a broader concept than crime. Though a desire for public safety includes a desire for low rates of crime, public safety connotes a more profound interest we have to live in a society where we feel secure pursuing our personal goals and fulfilling our life desires Using public safety as our criteria enables us to consider the ways incarceration affects our quality_of_life, especially through the way incarceration affects the informal social relations that promote the kind of profound social control that is a foundation for a sense of feeling safe.Three types of effects are described. Positive effects are those that improve public safety, negative effects reduce public safety, and "ambivalent" effects have the capacity to be both positive and negative. Five levels of social impacts on public safety are assessed:o Effects on individuals that change the way people act;o Effects on intimate relationships such as those with families and other loved ones;o Effects on social relationships that are felt as community_level outcomes;o Effects on institutions such as labor markets and the political economy;o Effects on democracy or social justice.Thus, the purpose of this paper is to summarize what is known, empirically and experientially, about the positive and negative ways incarceration affects levels of social expression.
