One of the first books to address what has come to be known as the philosophy of cosmology, Universes asks, "Why does the universe exist?", arguing that the universe is "fine tuned for producing life." For example, if the universe's early expansion speed had been smaller by one part in a million, then it would have recollapsed rapidly; with an equivalently tiny speed increase, no galaxies would have formed. Either way, this universe would have been lifeless.

Under what conditions does a physical system implement or realize a computation? Structuralism about computational implementation, espoused by Chalmers and others, holds that a physical system realizes a computation just in case the system instantiates a pattern of causal organization isomorphic to the computation’s formal structure. I argue against structuralism through counter-examples drawn from computer science. On my opposing view, computational implementation sometimes requires instantiating semantic properties that outstrip any relevant pattern of causal organization. In developing my argument, I defend (...) anti-individualism about computational implementation: relations to the social environment sometimes help determine whether a physical system realizes a computation. 1 The Physical Realization Relation2 Semantics and Computational Implementation3 Conforming to Instructions4 Implementing a Computer Program4.1 The denotational semantics of Scheme4.2 Worries about intentionality4.3 Worries about the natural numbers5 Implementing a Machine Model6 Bounded Structuralism7 Triviality Arguments8 Anti-individualism about Computational Implementation.

Excellence in sport performance is normally taken to be a matter of superior performance of physical movements or quantitative outcomes of movements. This paper considers whether a wider conception can be afforded by certain kinds of nature based sport. The interplay between technical skill and aesthetic experience in nature based sports is explored, and the extent to which it contributes to a distinction between different sport-based approaches to natural environments. The potential for aesthetic appreciation of environmental engagement is found to (...) be strongly dependent on whether or not environmental engagement is exploited for the end of producing a quantifiable result or enhancing technical skill. It is also argued that an existential rather than spectatorial attitude to aesthetic experience is offered by specifically nature oriented sport. Aesthetic experience achieved in this way is therefore neither passive nor detached, but extends Berleant's concept of participatory environmental aesthetics and underpins both an alternate (wide) conception of excellence in sport activity and a richer experience of aesthetic engagement than more objectivised standpoints.

Ducks lay eggs' is a true sentence, and `ducks are female' is a false one. Similarly, `mosquitoes carry the West Nile virus' is obviously true, whereas `mosquitoes don't carry the West Nile virus' is patently false. This is so despite the egg-laying ducks' being a subset of the female ones and despite the number of mosquitoes that don't carry the virus being ninety-nine times the number that do. Puzzling facts such as these have made generic sentences defy adequate semantic treatment. (...) However complex the truth conditions of generics appear to be, though, young children grasp generics more quickly and readily than seemingly simpler quantifiers such as `all' and `some'. I present an account of generics that not only illuminates the strange truth conditions of generics, but also explains how young children find them so comparatively easy to acquire. I then argue that generics give voice to our most cognitively primitive generalizations and that this hypothesis accounts for a variety of facts ranging from acquisition patterns to cross-linguistic data concerning the phonological articulation of operators. I go on to develop an account of the nature of these cognitively fundamental generalizations and argue that this account explains the strange truth-conditional behavior of generics. (shrink)

Sir Leslie Stephen (1832–1904), the founding editor of the Dictionary of National Biography, and a writer on philosophy, ethics, and literature, was educated at Eton, King's College London and Trinity College, Cambridge, where he remained as a fellow and a tutor for a number of years. Though a sickly child, he later became a keen and successful mountaineer, taking part in first ascents of nine peaks in the Alps. In 1871 he became editor of the Cornhill Magazine. During his (...) eleven-year tenure, he wrote two successful books on ethics, including The Science of Ethics in 1892, which was widely adopted as a standard textbook. This two-volume work, which was first published in 1896, brings together the lectures he gave to various ethical societies, mostly in London. Both volumes examine the ethical issues surrounding a range of topics including politics, morality, duty, and crime and punishment. (shrink)

Leslie Stephen (1832–1904) was a writer, philosopher and literary critic whose work was published widely in the nineteenth century. As a young man Stephen was ordained deacon, but he later became agnostic and much of his work reflects his interest in challenging popular religion. This two-volume work, first published in 1876, is no exception: it focuses on the eighteenth-century deist controversy and its effects, as well as the reactions to what Stephen saw as a revolution in thought. Comprehensive and (...) full of detailed analysis, this is an important work in the history of ideas. Volume 2 focuses on eighteenth-century moral philosophy, political philosophy and literature, and on the literary and religious reactions to the revolution in thought. Utilitarianism is discussed at length, as well as the work of thinkers such as Shaftesbury, Mandeville, Burke and Adam Smith. (shrink)

This research addresses the question of whether men and women in sales differ in their ethical attitudes and decision making. The study asked 209 subjects to respond to 20 ethical scenarios, half of which were "relational" and half "non-relational." The study concludes (1) that there are significant ethical differences between the sexes in situations that involve relational issues, but not in non-relational situations, and (2) that gender-based ethical differences change with age and years of experience. The implications of these finding (...) for sales organizations are discussed. (shrink)

Rooted in the field of cathedral studies, this paper draws into dialogue three bodies of knowledge: Edward Bailey’s notion of implicit religion that, among other things, highlights the continuing traction of the Christian tradition and Christian practice within secular societies; David Walker’s notion of the multiple ways through which in secular societies people may relate to the Christian tradition as embodied within the Anglican Church and John Fisher’s notion of spiritual wellbeing as conceptualised in relational terms. Against this conceptual background, (...) this paper draws on data provided by 1234 participants attending one of the Christmas Eve carol services in Liverpool Cathedral to explore the perceived impact of attendance on the spiritual health of people who do not believe in God and yet feel that Liverpool Cathedral is their cathedral, and it is this sense of belonging that brings them back at Christmas time.Contribution: Situated within the science of cathedral studies, this paper links in an original way three fields of discourse: Edward Bailey’s notion of implicit religion, David Walker’s notion of the four ways of belonging to God facilitated by the Anglican Church and John Fisher’s conceptualisation and operationalisation of the notion of spiritual wellbeing. The hypothesis developed from this original integration of theoretical perspectives is then tested empirically on data provided by 404 participants at carol services who do not believe in God.

Over three previous editions, Ten Theories of Human Nature has been a remarkably popular introduction to some of the most influential developments in Western and Eastern thought. This thoroughly revised fourth edition features substantial new chapters on Aristotle and on evolutionary theories of human nature; the latter centers on Edward O. Wilson but also outlines the ideas of Emile Durkheim, B. F. Skinner, Nikolaas Tinbergen, Konrad Lorenz, Noam Chomsky, and recent evolutionary psychology. This edition also includes a rewritten introduction that (...) invites readers (even if inclined toward fundamentalism, or to cultural relativism) to careful, critical thought about human nature; a useful new section that summarizes the history of ideas from the Stoics to the Enlightenment; and a new conclusion that suggests a way to synthesize the various theories. Lucid and accessible, Ten Theories of Human Nature, 4/e, compresses into a small space the essence of such ancient traditions as Confucianism, Hinduism, and the Old and New Testaments as well as the theories of Plato, Immanuel Kant, Karl Marx, Sigmund Freud, and Jean-Paul Sartre. The authors juxtapose the ideas of these and other thinkers and traditions in a way that helps readers understand how humanity has struggled to comprehend its nature. To encourage readers to think critically for themselves and to underscore the similarities and differences between the many theories, the book examines each one on four points--the nature of the universe, the nature of humanity, the diagnosis of the ills of humanity, and the proposed cure for these problems. Ideal for introductory courses in human nature, philosophy, religious studies, and intellectual history, Ten Theories of Human Nature, 4/e, will engage and motivate students and other readers to consider how we can understand and improve both ourselves and human society.

Quantum mechanics and probability theory share one peculiarity. Both have well established mathematical formalisms, yet both are subject to controversy about the meaning and interpretation of their basic concepts. Since probability plays a fundamental role in QM, the conceptual problems of one theory can affect the other. We first classify the interpretations of probability into three major classes: inferential probability, ensemble probability, and propensity. Class is the basis of inductive logic; deals with the frequencies of events in repeatable experiments; describes (...) a form of causality that is weaker than determinism. An important, but neglected, paper by P. Humphreys demonstrated that propensity must differ mathematically, as well as conceptually, from probability, but he did not develop a theory of propensity. Such a theory is developed in this paper. Propensity theory shares many, but not all, of the axioms of probability theory. As a consequence, propensity supports the Law of Large Numbers from probability theory, but does not support Bayes theorem. Although there are particular problems within QM to which any of the classes of probability may be applied, it is argued that the intrinsic quantum probabilities are most naturally interpreted as quantum propensities. This does not alter the familiar statistical interpretation of QM. But the interpretation of quantum states as representing knowledge is untenable. Examples show that a density matrix fails to represent knowledge. (shrink)

Fodor advocates a view of cognitive processes as computations defined over the language of thought (or Mentalese). Even among those who endorse Mentalese, considerable controversy surrounds its representational format. What semantically relevant structure should scientific psychology attribute to Mentalese symbols? Researchers commonly emphasize logical structure, akin to that displayed by predicate calculus sentences. To counteract this tendency, I discuss computational models of navigation drawn from probabilistic robotics. These models involve computations defined over cognitive maps, which have geometric rather than logical (...) structure. They thereby demonstrate the possibility of rational cognitive processes in an exclusively non-logical representational medium. Furthermore, they offer much promise for the empirical study of animal navigation. (shrink)

Alston, Searle, and Williamson advocate the restrictive model of assertion , according to which certain constitutive assertoric norms restrict which propositions one may assert. Sellars and Brandom advocate the dialectical model of assertion , which treats assertion as constituted by its role in the game of giving and asking for reasons. Sellars and Brandom develop a restrictive version of the dialectical model. I explore a non-restrictive version of the dialectical model. On such a view, constitutive assertoric norms constrain how one (...) must react if an interlocutor challenges one's assertion, but they do not constrain what one should assert in the first place. I argue that the non-restrictive dialectical perspective can accommodate various linguistic phenomena commonly taken to support the restrictive model. 1. (shrink)

This book has a wonderful introduction and afterword by Marjorie Hewitt Suchocki. From beginning to end, this tri-authored work offers an integrated treatment of process theology, pneumology, and ecclesiology for the benefit of local Christian congregations.Among the three voices at work in this book, John Cobb provides an important primer on Whitehead's views of possibilities, experience, and relationships. Opening each of the book's three parts, Cobb both lays the groundwork and provides a strong framing for pneumology on the basis of (...) Whiteheadian thought. The frame for the Spirit is a broad one, calling for diversity and spontaneity. Lest the spiritual become too ethereal, Cobb reminds us of Whitehead's emphasis on experience and responsiveness to the world around us. Our freedom involves a self-determination that actualizes our own happiness and our contribution to others (111). Cobb's sections build a frame for the sections written by Epperly and Nancarrow, and they also encourage continued reading of Whitehead. (However, the book's lack of an index or a resource page for this kind of growth is a shortcoming.)Epperly offers in each of the book's three sections efforts at honing the concept of spirituality. As a concept, spirituality is in danger of a vacuousness that has no leverage in the life experience of the practitioner. Epperly does not succumb. He explicates important conduits of the spirit: embodiment, imagination, affirmative awareness, and compassion. Epperly provides a definition of spirituality as an adventurous journey of compassion. Spirituality is less a state of being and more of an exploration or a becoming as one relates to the surrounding world. He works the definition of spirituality with a prism-like beauty over the course of the three sections, integrating important persons from various cultures and inviting the reader to imagine their own spiritual past and potential future contributions.In each of the three sections, Nancarrow brings ecclesiology into the mix, thus making the book an essential for pastors who care about the pragmatics of process in the community of a local congregation. Nancarrow's chapters might be best characterized as how-to chapters helping church folk revisit the routines of liturgy, small groups, and the sacrament of communion. He encourages specific practices to engage liturgy, freshen perception, and potentially awaken hearts that can grow dull in rote practices of worship. Discernment and group work receives step-by-step attention. It is not lost on the reader that Nancarrow means to connect the care of facilitation in groups to the group's experience of the Spirit's call. Quite deftly, he closes the book with attention to the sacrament of communion in which “imagination, intellect, will, memory, emotion, sensation, and physicality are all engaged” (137).In short, The Call of the Spirit does more than talk about the Spirit. The book provides a philosophy and theology for practicing into the Spirit and helping others do the same. The authors believe in the readers’ intellect, deep-seated compassion, and commitment to the communities from which the adventure might play out in the most profound ways. (shrink)

Sensorimotor psychology studies the mental processes that control goal-directed bodily motion. Recently, sensorimotor psychologists have provided empirically successful Bayesian models of motor control. These models describe how the motor system uses sensory input to select motor commands that promote goals set by high-level cognition. I highlight the impressive explanatory benefits offered by Bayesian models of motor control. I argue that our current best models assign explanatory centrality to a robust notion of mental representation. I deploy my analysis to defend intentional (...) realism, to rebut eliminativism and instrumentalism regarding mental representation, and to explore the relation between intentionality and normativity.

I argue that maps do not feature predication, as analyzed by Frege and Tarski. I take as my foil (Casati and Varzi, Parts and places, 1999), which attributes predication to maps. I argue that the details of Casati and Varzi’s own semantics militate against this attribution. Casati and Varzi emphasize what I call the Absence Intuition: if a marker representing some property (such as mountainous terrain) appears on a map, then absence of that marker from a map coordinate signifies absence (...) of the corresponding property from the corresponding location. Predication elicits nothing like the Absence Intuition. “F(a)” does not, in general, signify that objects other than a lack property F. On the basis of this asymmetry, I argue that attaching a marker to map coordinates is a different mode of semantic composition than attaching a predicate to a singular term. (shrink)

Lewis proved a Dutch book theorem for Conditionalization. The theorem shows that an agent who follows any credal update rule other than Conditionalization is vulnerable to bets that inflict a sure loss. Lewis’s theorem is tailored to factive formulations of Conditionalization, i.e. formulations on which the conditioning proposition is true. Yet many scientific and philosophical applications of Bayesian decision theory require a non-factive formulation, i.e. a formulation on which the conditioning proposition may be false. I prove a Dutch book theorem (...) tailored to non-factive Conditionalization. I also discuss the theorem’s significance. (shrink)

Conditionalization is a norm that governs the rational reallocation of credence. I distinguish between factive and non-factive formulations of Conditionalization. Factive formulations assume that the conditioning proposition is true. Non-factive formulations allow that the conditioning proposition may be false. I argue that non-factive formulations provide a better foundation for philosophical and scientific applications of Bayesian decision theory. I furthermore argue that previous formulations of Conditionalization, factive and non-factive alike, have almost universally ignored, downplayed, or mishandled a crucial causal aspect of (...) Conditionalization. To formulate Conditionalization adequately, one must explicitly address the causal structure of the transition from old credences to new credences. I offer a formulation of Conditionalization that takes these considerations into account, and I compare my preferred formulation with some prominent formulations found in the literature. (shrink)

This article provides an ecological theory of face perception that elucidates the basis of the various perceptions. It then reviews research on first impressions elicited by facial qualities that are associated with fitness, emotion, race, age, and sex, in each case making links to ecological theory. It aims to identify facial qualities that inform social perceptions and reflect the zeitgeist at the time in social psychology. The emphasis is on understanding the cognitive mechanisms engaged in social perception, and this is (...) typically accomplished by providing information about social qualities in lists of trait words. The article demonstrates face perception research pertinent to the detection of socially relevant qualities in faces—attractiveness, emotions, race, age, and sex—as well as associated behavioral affordances, which have typically been assessed by trait ratings.

I articulate and defend a new theory of what it is for a physical system to implement an abstract computational model. According to my descriptivist theory, a physical system implements a computational model just in case the model accurately describes the system. Specifically, the system must reliably transit between computational states in accord with mechanical instructions encoded by the model. I contrast my theory with an influential approach to computational implementation espoused by Chalmers, Putnam, and others. I deploy my theory (...) to illuminate the relation between computation and representation. I also rebut arguments, propounded by Putnam and Searle, that computational implementation is trivial.

Smith, Glass, and Miller have reported a meta-analysis of over 500 studies comparing some form of psychological therapy with a control condition. They report that when averaged over all dependent measures of outcome, psychological therapy is. 85 standard deviations better than the control treatment. We examined the subset of studies included in the Smith et al. metaanalysis that contained a psychotherapy and a placebo treatment. The median of the mean effect sizes for these 32 studies was. 15. There was a (...) nonsignificant inverse relationship between mean outcome and the following: sample size, duration of therapy, use of measures of outcome other than undisguised self-report, measurement of outcome at follow-up, and use of real patients rather than subjects solicited for the purposes of participation in a research study. A qualitative analysis of the studies in terms of the type of patient involved indicates that those using psychiatric outpatients had essentially zero effect sizes and that none using psychiatric inpaticnts provide convincing evidence for psychotherapeutic effectiveness. The onty studies clearly demonstrating significant effects of psychotherapy were the ones that did not use real patients. For the most part, these studies involved small samples of subjects and brief treatments, occasionally described in quasibeliavioristic language. It was concluded that for real patients there is no evidence that the benefits of psychotherapy are greater than those of placebo treatment. (shrink)

Turing computation over a non-linguistic domain presupposes a notation for the domain. Accordingly, computability theory studies notations for various non-linguistic domains. It illuminates how different ways of representing a domain support different finite mechanical procedures over that domain. Formal definitions and theorems yield a principled classification of notations based upon their computational properties. To understand computability theory, we must recognize that representation is a key target of mathematical inquiry. We must also recognize that computability theory is an intensional enterprise: it (...) studies entities as represented in certain ways, rather than entities detached from any means of representing them.

Many philosophers worry that the classical computational theory of mind (CTM) engenders epiphenomenalism. Building on Block’s (1990) discussion, I formulate a particularly troubling version of this worry. I then present a novel solution to CTM’s epiphenomenalist conundrum. I develop my solution within an interventionist theory of causal relevance. My solution departs substantially from orthodox versions of CTM. In particular, I reject the widespread picture of digital computation as formal syntactic manipulation.1.

This paper discusses conditional probability $$P$$ P , or the probability of A given B. When $$P>0$$ P > 0 , the ratio formula determines $$P$$ P . When $$P=0$$ P = 0 , the ratio formula breaks down. The Borel–Kolmogorov paradox suggests that conditional probabilities in such cases are indeterminate or ill-posed. To analyze the paradox, I explore the relation between probability and intensionality. I argue that the paradox is a Frege case, similar to those that arise in many (...) probabilistic and non-probabilistic contexts. The paradox vividly illustrates how an agent’s way of representing an entity can rationally influence her credal assignments. I deploy my analysis to defend Kolmogorov’s relativistic treatment of conditional probability. (shrink)

This paper discusses how to update one’s credences based on evidence that has initial probability 0. I advance a diachronic norm, Kolmogorov Conditionalization, that governs credal reallocation in many such learning scenarios. The norm is based upon Kolmogorov’s theory of conditional probability. I prove a Dutch book theorem and converse Dutch book theorem for Kolmogorov Conditionalization. The two theorems establish Kolmogorov Conditionalization as the unique credal reallocation rule that avoids a sure loss in the relevant learning scenarios.

Dialectical egalitarianism holds that every asserted proposition requires defence when challenged by an interlocutor. This view apparently generates a vicious 'regress of justifications', since an interlocutor can challenge the premises through which a speaker defends her original assertion, and so on ad infinitum . To halt the regress, dialectical foundationalists such as Adler, Brandom, Leite, and Williams propose that some propositions require no defence in the light of mere requests for justification. I argue that the putative regress is not worrisome (...) and that egalitarianism can handle it quite satisfactorily. I also defend a positive view that combines an anti-foundationalist conception of dialectical interaction with a foundationalist conception of epistemic justification. (shrink)

Dialectical foundationalists, including Adler, Brandom, Leite, and Williams, claim that some asserted propositions do not require defense just because an interlocutor challenges them. By asserting such a proposition, the speaker shifts the burden of proof to her interlocutor. Dialectical egalitarians claim that all asserted propositions require defense when challenged. I elucidate the dispute between dialectical foundationalists and egalitarians, and I defend a broadly egalitarian stance against several prominent objections.

I critique an ancient argument for the possibility of non-linguistic deductive inference. The argument, attributed to Chrysippus, describes a dog whose behavior supposedly reflects disjunctive syllogistic reasoning. Drawing on contemporary robotics, I urge that we can equally well explain the dog's behavior by citing probabilistic reasoning over cognitive maps. I then critique various experimentally-based arguments from scientific psychology that echo Chrysippus's anecdotal presentation.

The perceptual system estimates distal conditions based upon proximal sensory input. It typically exploits information from multiple cues across and within modalities: it estimates shape based upon visual and haptic cues; it estimates depth based upon convergence, binocular disparity, motion parallax, and other visual cues; and so on. Bayesian models illuminate the computations through which the perceptual system combines sensory cues. I review key aspects of these models. Based on my review, I argue that we should posit co-referring perceptual representations (...) corresponding to distinct sensory cues. For example, the perceptual system represents a distal size using a representation canonically linked with vision and a distinct representation canonically linked with touch. Distinct co-referring perceptual representations represent the same denotation, but they do so under different modes of presentation. Bayesian cue combination models demonstrate that psychological explanation of perception should attend to mode of presentation and not simply to denotation. (shrink)
