People may have open minds on whether a life-extending drug or technology is going to be developed before their sixties and may strongly desire that development. Do they therefore hope that it occurs? Do they hope for it in the substantive sense of “pinning their hopes” on the development? No, they do not. Hoping for a prospect in that sense certainly presupposes having an open mind on whether it will occur and having a desire for its occurrence. But, more crucially, (...) it means investing the prospect with a characteristic, galvanizing, and orientating role: it involves setting aside doubts about the possible nonoccurrence of the prospect and acting accordingly. This article offers a characterization of hope in that substantive sense and argues both that it can be rational and that it is ubiquitous. (shrink)

What determines whether an action is right or wrong? Morality, Rules, and Consequences: A Critical Reader explores for students and researchers the relationship between consequentialist theory and moral rules. Most of the chapters focus on rule consequentialism or on the distinction between act and rule versions of consequentialism. Contributors, among them the leading philosophers in the discipline, suggest ways of assessing whether rule consequentialism could be a satisfactory moral theory. These essays, all of which are previously unpublished, provide students in (...) moral philosophy with essential material and ask key questions on just what the criteria for an adequate moral theory might be.

Means-based harms are frequently seen as forbidden, even when they lead to a greater good. But, are there mitigating factors? Results from five experiments show that judgments about means-based harms are modulated by: 1) Pareto considerations (was the harmed person made worse off?), 2) the directness of physical contact, and 3) the source of the threat (e.g. mechanical, human, or natural). Pareto harms are more permissible than non-Pareto harms, Pareto harms requiring direct physical contact are less permissible than those that (...) do not, and harming someone who faces a mechanical threat is less permissible than harming someone who faces a non-mechanical threat. These results provide insight into the rich representational structure underlying folk-moral computations, including both the independent and interacting roles of the inevitability, directness and source of harm.

Abstract This paper offers an appraisal of Phillip Pettit's approach to the problem how a merely finite set of examples can serve to represent a determinate rule, given that indefinitely many rules can be extrapolated from any such set. I argue that Pettit's so-called ethnocentric theory of rule-following fails to deliver the solution to this problem he sets out to provide. More constructively, I consider what further provisions are needed in order to advance Pettit's general approach (...) to the problem. I conclude that what is needed is an account that, whilst it affirms the view that agents' responses are constitutively involved in the exemplification of rules, does not allow such responses the pride of place they have in Pettit's theory.

Shows that the very same asymmetries that arise for intentionally also arise from deciding, desiring, in favor of, opposed to, and advocating. It seems that the phenomenon is not due to anything about the concept of intentional action in particular. Rather, the effects observed for the concept of intentional action should be regarded as just one manifestation of the pervasive impact of moral judgment.

David Lewis [1988; 1996] canvases an anti-Humean thesis about mental states: that the rational agent desires something to the extent that he or she believes it to be good. Lewis offers and refutes a decision-theoretic formulation of it, the 'Desire-as-Belief Thesis'. Other authors have since added further negative results in the spirit of Lewis's. We explore ways of being anti-Humean that evade all these negative results. We begin by providing background on evidential decision theory and on Lewis's negative results. We (...) then introduce what we call the indexicality loophole: if the goodness of a proposition is indexical, partly a function of an agent's mental state, then the negative results have no purchase. Thus we propose a variant of Desire-as-Belief that exploits this loophole. We argue that a number of meta-ethical positions are committed to just such indexicality. Indeed, we show that with one central sort of evaluative belief--the belief that an option is right--the indexicality loophole can be exploited in various interesting ways. Moreover, on some accounts, 'good' is indexical in the same way. Thus, it seems that the anti-Humean can dodge the negative results. (shrink)

In this book, Phillip Wiebe examines religious, spiritual, and mystical experiences, assessing how these experiences appear to implicate a spiritual order. Despite the current prevalence of naturalism and atheism, he argues that experiences purporting to have a religious or spiritual significance deserve close empirical investigation. Wiebe surveys the broad scope of religious experience and considers different types of evidence that might give rise to a belief in phenomena such as spirits, paranormal events, God, and an afterlife. He demonstrates that (...) there are different explanations and interpretations of religious experiences, both because they are typically personal accounts, and they suggest a reality that is often unobservable. Wiebe also addresses how to evaluate evidence for theories that postulate unobservables in general, and a Theory of Spirits in particular. Calling for more rigorous investigation of these phenomena, Wiebe frames the study of religious experience among other accepted social sciences that seek to understand religion. (shrink)

Business ethics is a topic receiving much attention in the literature. However, the term 'business ethics' is not adequately defined. Typical definitions refer to the rightness or wrongness of behavior, but not everyone agrees on what is morally right or wrong, good or bad, ethical or unethical. To complicate the problem, nearly all available definitions exist at highly abstract levels. This article focuses on contemporary definitions of business ethics by business writers and professionals and on possible areas of agreement among (...) the available definitions. Then a definition is synthesized that is broad enough to cover the field of management in a sense as full as most managers might conceive of it. (shrink)

God is said to be Spirit, but the language of spirit is ignored in contemporary philosophy of religion. As well as exploring the notion of spirit in Hegel, Romanticism and Kierkegaard, participants explore the view that God is a spirit without a body, and the relations between "spirit" and "truth.".

Are companies, churches, and states genuine agents? Or are they just collections of individuals that give a misleading impression of unity? This question is important, since the answer dictates how we should explain the behaviour of these entities and whether we should treat them as responsible and accountable on the model of individual agents. Group Agency offers a new approach to that question and is relevant, therefore, to a range of fields from philosophy to law, politics, and the social sciences. (...) Christian List and Philip Pettit argue that there really are group or corporate agents, over and above the individual agents who compose them, and that a proper approach to the social sciences, law, morality, and politics must take account of this fact. Unlike some earlier defences of group agency, their account is entirely unmysterious in character and, despite not being technically difficult, is grounded in cutting-edge work in social choice theory, economics, and philosophy.

One of the hallmark themes of Karl Popper’s approach to the social sciences was the insistence that when social scientists are members of the society they study, then they are liable to affect that society. In particular, they are liable to affect it in such a way that the claims they make lose their validity. “The interaction between the scientist’s pronouncements and social life almost invariably creates situations in which we have not only to consider the truth of such pronouncements, (...) but also their actual influence on future developments. The social scientist may be striving to find the truth; but, at the same time, he must always be exerting a definite influence upon society. The very fact that his pronouncements do exert an influence destroys their objectivity.” (Popper 1963. (shrink)

Arguments for Restrictivism – the position that we are rarely free– have been proposed by incompatibilists Peter van Inwagen and David Vander Laan among others. This article is concerned much more with these arguments than with quantifying the frequency of free actions. There are two general ways to argue for restrictivism. First, one may take a Negative Strategy, arguing that the situations in which one is not free are common and predominant. Second, one may focus on situations in which one (...) is apparently free, and argue directly that these situations are rare – the Inventory Strategy. I conclude that both types of arguments for restrictivism are unconvincing. (shrink)

Reason and Value collects fifteen brand-new papers by leading contemporary philosophers on themes from the moral philosophy of Joseph Raz. The subtlety and power of Raz's reflections on ethical topics - including especially his explorations of the connections between practical reason and the theory of value - make his writings a fertile source for anyone working in this area. The volume honours Raz's accomplishments in the area of ethical theorizing, and will contribute to an enhanced appreciation of the significance of (...) his work for the subject. (shrink)

In his most recent book, Philip Pettit presents and defends a “republican” political philosophy that stems from a tradition that includes Cicero, Machiavelli, James Harrington, Locke, Montesquieu, Rousseau, and Madison. The book provides an interpretation of what is distinctive about republicanism—namely, Pettit claims, its notion of freedom as nondomination. He sketches the history of this notion, and he argues that it entails a unique justification of certain political arrangements and the virtues of citizenship that would make those arrangements (...) possible. Of historical and philosophical interest, he stresses, is the fundamental contrast between freedom as nondomination and slavery. Joseph Priestly, for instance, invoked this contrast in defending the cause of the American Revolution, and in 1769 declared, incredibly, that if the parliament of Great Britain continued to tax the American colonies, “the colonists will be reduced to a state of as complete servitude, as any people of which there is an account in history”. Those opposed to American independence, among them Jeremy Bentham, relied instead on a Hobbesian notion of freedom as noninterference, using it to argue that the colonists were no more interfered with by the British government than were citizens of Britain. Drawing out this contrast, Pettit aims to establish that a republican view of freedom better supports the institutions of a constitutional democracy than does liberalism. His account of the distinguishing characteristics and strengths of republicanism is, however, only partially successful. Neither his case that a republican notion of freedom provides for a more solid defense of democratic institutions and constitutional protections than is available within liberalism, nor his argument that republicanism can better address “private” injustices, is convincing.

The mass movement of people across the globe constitutes a major feature of world politics today. -/- Whatever the cause of the movement - often war, famine, economic hardship, political repression or climate change - the governments of western capitalist states see this 'torrent of people in flight' as a serious threat to their stability and the scale of this migration indicates a need for a radical re-thinking of both political theory and practice, for the sake of political, social and (...) economic justice. -/- This book argues that there is at present a serious gap between the legal and social practices of immigration and naturalisation in liberal democratic states and any theoretical justification for such practices that can be made within the tradition of liberal political philosophy. How can liberal states develop institutions of democratic citizenship and at the same time justifiably exclude 'outsiders' from participating in those institutions? The book examines various responses to this contradiction within the liberal tradition, and finds none of them satisfactory - there are no consistently liberal justifications for immigration control and this has serious implications both for liberal practice and theory.

To properly understand behavior, we must obtain both ultimate and proximate explanations. Put briefly, ultimate explanations are concerned with why a behavior exists, and proximate explanations are concerned with how it works. These two types of explanation are complementary and the distinction is critical to evolutionary explanation. We are concerned that they have become conflated in some areas of the evolutionary literature on human behavior. This article brings attention to these issues. We focus on three specific areas: the evolution of (...) cooperation, transmitted culture, and epigenetics. We do this to avoid confusion and wasted effort—dangers that are particularly acute in interdisciplinary research. Throughout this article, we suggest ways in which misunderstanding may be avoided in the future. (shrink)

Composition as identity, as I understand it, is a theory of the composite structure of reality. The theory’s underlying logic is irreducibly plural; its fundamental primitive is a generalized identity relation that takes either plural or singular arguments. Strong versions of the theory that incorporate a generalized version of the indiscernibility of identicals are incompatible with the framework of plural logic, and should be rejected. Weak versions of the theory that are based on the idea that composition is merely analogous (...) to identity are too weak to be interesting, lacking in metaphysical consequence. I defend a moderate version according to which composition is a kind of identity, and argue that the difference is metaphysically substantial, not merely terminological. I then consider whether the notion of generalized identity, though fundamental, can be elucidated in modal terms by reverse engineering Hume’s Dictum. Unfortunately, for realists about possible worlds, such as myself,... (shrink)

Niche construction refers to the activities of organisms that bring about changes in their environments, many of which are evolutionarily and ecologically consequential. Advocates of niche construction theory (NCT) believe that standard evolutionary theory fails to recognize the full importance of niche construction, and consequently propose a novel view of evolution, in which niche construction and its legacy over time (ecological inheritance) are described as evolutionary processes, equivalent in importance to natural selection. Here, we subject NCT to critical evaluation, in (...) the form of a collaboration between one prominent advocate of NCT, and a team of skeptics. We discuss whether niche construction is an evolutionary process, whether NCT obscures or clarifies how natural selection leads to organismal adaptation, and whether niche construction and natural selection are of equivalent explanatory importance. We also consider whether the literature that promotes NCT overstates the significance of niche construction, whether it is internally coherent, and whether it accurately portrays standard evolutionary theory. Our disagreements reflect a wider dispute within evolutionary theory over whether the neo-Darwinian synthesis is in need of reformulation, as well as different usages of some key terms (e.g., evolutionary process).

: The transplantation of adult human neural stem cells into prenatal non-humans offers an avenue for studying human neural cell development without direct use of human embryos. However, such experiments raise significant ethical concerns about mixing human and nonhuman materials in ways that could result in the development of human-nonhuman chimeras. This paper examines four arguments against such research, the moral taboo, species integrity, "unnaturalness," and human dignity arguments, and finds the last plausible. It argues that the transfer of human (...) brain or retinal stem cells to nonhuman embryos would not result in the development of human-nonhuman chimeras that denigrate human dignity, provided such stem cells are dissociated. The article provides guidelines that set ethical boundaries for conducting such research that are consonant with the requirements of human dignity. (shrink)

This study describes discourse features of messages posted to an Internet discussion forum about depression based on the analysis of a small corpus of message texts. The message texts were classified into three types: problem messages, advice messages and thanks messages, and salient discourse features of each message type were described and analyzed in terms of discourse function. Features of problem messages included: frequent use of metaphorical language to describe symptoms, use of or type questions to request advice, and a (...) general lack of direct requests for advice. Advice messages were characterized by casual style and exhibited a variety of discourse patterns with the common function of expressing positive regard and solidarity. The occurrence of these patterns can be related to the special interpersonal needs associated with the discourse function of giving advice. Thanks messages were responses to advice messages, and usually included some expression of thanks for advice, but interestingly, thanks message writers never indicated that they had acted upon or would act upon the advice they received.

It follows from Humean principles of plenitude, I argue, that island universes are possible: physical reality might have 'absolutely isolated' parts. This makes trouble for Lewis's modal realism; but the realist has a way out. First, accept absolute actuality, which is defensible, I argue, on independent grounds. Second, revise the standard analysis of modality: modal operators are 'plural', not 'individual', quantifiers over possible worlds. This solves the problem of island universes and confers three additional benefits: an 'unqualified' principle of compossibility (...) can be accepted; the possibility of nothing can be accommodated; and the identity of indiscernible worlds can be decisively refuted.

This volume contains eighteen papers, three with new postscripts, that were written over the past 35 years. Five of the papers have not been previously published. Together they provide a comprehensive account of modal reality—the realm of possible worlds—from a Humean perspective, with excursions into neighboring topics in metaphysics. Part 1 sketches an account of reality as a whole, both the mathematical and the modal, defending a form of plenitudinous realism: every consistent proposition is true of some portion of reality. (...) Part 2 presents and defends a realist theory of concrete possible worlds with an absolute ontological distinction between the actual and the merely possible. Part 3 presents and defends a Humean account of modal plenitude, formulating and endorsing principles of recombination, of plenitude of possible structures, and of plenitude of alien contents. Part 4 applies the Humean account to truthmaking, mereology, spacetime, and quantities. I argue that holding fast to Humean strictures leads to views that differ in radical ways from those put forth by contemporary metaphysicians. (shrink)

In this chapter, I survey what I call Lewisian approaches to modality: approaches that analyze modality in terms of concrete possible worlds and their parts. I take the following four theses to be characteristic of Lewisian approaches to modality. (1) There is no primitive modality. (2) There exists a plurality of concrete possible worlds. (3) Actuality is an indexical concept. (4) Modality de re is to be analyzed in terms of counterparts, not transworld identity. After an introductory section in which (...) I motivate analyzing modality in terms of possible worlds, I devote one section to each of these four theses. For each thesis, I take Lewis’s interpretation and defense as my starting point. I then consider and endorse alternative ways of accepting the thesis, some of which disagree substantially with Lewis’s interpretation or defense. There is more than one way to be a Lewisian about modality. (shrink)

During the past decade ethical theory has been in a lively state of development, and three basic approaches to ethics - Kantian ethics, consequentialism, and virtue ethics - have assumed positions of particular prominence.

According to David Lewis, a realist about possible worlds must hold that actuality is relative: the worlds are ontologically all on a par; the actual and the merely possible differ, not absolutely, but in how they relate to us. Call this 'Lewisian realism'. The alternative, 'Leibnizian realism', holds that actuality is an absolute property that marks a distinction in ontological status. Lewis presents two arguments against Leibnizian realism. First, he argues that the Leibnizian realist cannot account for the contingency of (...) actuality. Second, he argues that the Leibnizian realist cannot explain why skepticism about one's own actuality is absurd. In this paper, I mount a defense of Leibnizian realism. (shrink)

Suppose that the members of a group each hold a rational set of judgments on some interconnected questions, and imagine that the group itself has to form a collective, rational set of judgments on those questions. How should it go about dealing with this task? We argue that the question raised is subject to a difficulty that has recently been noticed in discussion of the doctrinal paradox in jurisprudence. And we show that there is a general impossibility theorem that that (...) difficulty illustrates. Our paper describes this impossibility result and provides an exploration of its significance. The result naturally invites comparison with Kenneth Arrow's famous theorem (Arrow, 1963 and 1984; Sen, 1970) and we elaborate that comparison in a companion paper (List and Pettit, 2002). The paper is in four sections. The first section documents the need for various groups to aggregate its members' judgments; the second presents the discursive paradox; the third gives an informal statement of the more general impossibility result; the formal proof is presented in an appendix. The fourth section, finally, discusses some escape routes from that impossibility. (shrink)

Was Plato a Pythagorean? Plato's students and earliest critics thought so, but scholars since the nineteenth century have been more skeptical. With this probing study, Phillip Sidney Horky argues that a specific type of Pythagorean philosophy, called "mathematical" Pythagoreanism, exercised a decisive influence on fundamental aspects of Plato's philosophy. The progenitor of mathematical Pythagoreanism was the infamous Pythagorean heretic and political revolutionary Hippasus of Metapontum, a student of Pythagoras who is credited with experiments in harmonics that led to innovations (...) in mathematics. The innovations of Hippasus and other mathematical Pythagoreans, including Empedocles of Agrigentum, Epicharmus of Syracuse, Philolaus of Croton, and Archytas of Tarentum, presented philosophers like Plato with novel ways to reconcile empirical knowledge with abstract mathematical theories. Plato and Pythagoreanism demonstrates how mathematical Pythagoreanism established many of the fundamental philosophical questions Plato dealt with in his central dialogues, including Cratylus, Phaedo, Republic, Timaeus, and Philebus. In the process, it also illuminates the historical significance of the mathematical Pythagoreans, a group whose influence on the development of philosophical and scientific methods has been obscured since late antiquity. The picture that results is one in which Plato inherits mathematical Pythagorean method only to transform it into a powerful philosophical argument about the essential relationships between the cosmos and the human being.

Blurb & Contents Readings from Physics Today With over 300 photographs and illustrations, this volume is a valuable library reference, a useful supplementary text for a wide range of courses, and stimulating leisure reading for physicists and non- physicists alike.

In this paper, I critique two conceptions of mechanisms, namely those put forth by Stuart Glennan (Erkenntnis 44:49–71, 1996; Philosophy of Science 69:S342–S353, 2002) and Machamer et al. (Philosophy of Science 67:1–25, 2000). Glennan’s conception, I argue, cannot account for mechanisms involving negative causation because of its interactionist posture. MDC’s view encounters the same problem due to its reificatory conception of activities—this conception, I argue, entails an onerous commitment to ontological dualism. In the place of Glennan and MDC, I propose (...) a “modified conception” of mechanisms, which (a) obviates the problem of negative causation by reinterpreting MDC’s activities according to a “descriptivist” account, and (b) avoids MDC’s problem by postulating a monistic ontology of entities. Thus, by solving these problems, my modified conception offers a cogent, more adequate alternative to Glennan’s and MDC’s conceptions of mechanisms. (shrink)

This article re-examines the theoretical basis for environmental and heritage interpretation in tourist settings in the light of hermeneutic philosophy. It notes that the pioneering vision of heritage interpretation formulated by Freeman Tilden envisaged a broadly educational, ethically informed and transformative art. By contrast, current cognitive psychological attempts to reduce interpretation to the monological transmission of information, targeting universal but individuated cognitive structures, are found to be wanting. Despite growing signs of diversity, this information processing approach to interpretation remains dominant. (...) The article then presents the alternative paradigm of hermeneutics through the works of Schleiermacher, Dilthey, Heidegger and Gadamer, to provide a broader interpretation of interpretation. This not only captures the essence of Tilden’s definition but construes heritage interpretation as a more inclusive, culturally situated, critically reflexive and dialogical practice. (shrink)

Phillip Cary argues that Augustine invented or created the concept of self as an inner space--as space into which one can enter and in which one can find God. This concept of inwardness, says Cary, has worked its way deeply into the intellectual heritage of the West and many Western individuals have experienced themselves as inner selves. After surveying the idea of inwardness in Augustine's predecessors, Cary offers a re-examination of Augustine's own writings, making the controversial point that in (...) his early writings Augustine appears to hold that the human soul is quite literally divine. Cary goes on to contend that the crucial Book 7 of the Confessions is not a historical report of Augustine's "conversion" experience, but rather an explanation of his intellectual development over time.

I am a realist of a metaphysical stripe. I believe in an immense realm of "modal" and "abstract" entities, of entities that are neither part of, nor stand in any causal relation to, the actual, concrete world. For starters: I believe in possible worlds and individuals; in propositions, properties, and relations (both abundantly and sparsely conceived); in mathematical objects and structures; and in sets (or classes) of whatever I believe in. Call these sorts of entity, and the reality they comprise, (...) metaphysical. In contrast, call the actual, concrete entities, and the reality they comprise, physical. Physical and metaphysical reality together comprise all that there is. In this paper, it is not my aim to defend realism about any particular metaphysical sort of entity. Rather, I ask quite generally whether and how any brand of realism about metaphysical sorts of entity could be justified? (shrink)

Social work is a contested tradition, torn between the demands of social governance and autonomy. Today, this struggle is reflected in the division between the dominant, neoliberal agenda of service provision and the resistance offered by various critical perspectives employed by disparate groups of practitioners serving diverse communities. Critical social work challenges oppressive conditions and discourses, in addition to addressing their consequences in individuals’ lives. However, very few recent critical theorists informing critical social work have advocated revolution. A challenging exception (...) can be found in the work of Cornelius Castoriadis (1922–97), whose explication of ontological underdetermination and creation evades the pitfalls of both structural determinism and post-structural relativism, enabling an understanding of society as the contested creation of collective imaginaries in action and a politics of radical transformation. On this basis, we argue that Castoriadis’s radical-democratic revisioning of revolutionary praxis can help in reimagining critical social work’s emancipatory potential. (shrink)

The article explicates a notion of prudence according to which an agent acts prudently if he acts so as to satisfy not only his present preferences, but his past and future preferences as well. A simplified decision-theoretic framework is developed within which three analyses of prudence are presented and compared. That analysis is defended which can best handle cases in which an agent's present act will affect his future preferences.

The term 'fascism' continues to be very much in currency in Philippines society. To the Filipino people, its meaning is often drawn from pained memory of wholesale deprivation of democratic rights and large-scale human rights abuses. Yet, to many, the fear of fascism has still to give way to a deeper understanding of this menace. This may hold true even among those belonging to the progressive movement. One Marxist philosopher and theoretician who gave extended treatment of the issues surrounding the (...) character and conditions giving rise to fascism was Nicos Poulantzas, whose theory is employed here to interrogate the debates about fascism in the post-Marcos Philippines context.

What is one to make of Sartre's treatment of his waiter in one of his famous analyses of bad faith? The example is supposed to be an obvious one, but the more we examine it, the less obvious it becomes. Let us remind ourselves of Sartre's example: Let us consider this waiter in the café. His movement is quick and forward, a little too precise, a little too rapid. He comes toward the patrons with a step a little too quick. (...) He bends forward a little too eagerly; his voice, his eyes express an interest a little too solicitous for the order of the customer. Finally there he returns, trying to imitate in his walk the inflexible stiffness of some kind of automaton while carrying his tray with a recklessness of a tight-rope walker by putting it in a perpetually unstable, perpetually broken equilibrium which he perpetually re-establishes by a light movement of the arm and hand.

If realism about possible worlds is to succeed in eliminating primitive modality, it must provide an 'analysis' of possible world: nonmodal criteria for demarcating one world from another. This David Lewis has done. Lewis holds, roughly, that worlds are maximal unified regions of logical space. So far, so good. But what Lewis means by 'unification' is too narrow, I think, in two different ways. First, for Lewis, all worlds are (almost) 'globally' unified: at any world, (almost) every part is directly (...) linked to (almost) every other part. I hold instead that some worlds are 'locally' unified: at some worlds, parts are directly linked only to "neighboring" parts. Second, for Lewis, each world is (analogically) 'spatio-temporally' unified; every world is 'spatio-temporally' isolated from every other. I hold instead: a world may be unified by nonspatio-temporal relations; every world is 'absolutely' isolated from every other. If I am right, Lewis's conception of logical space is impoverished: perfectly respectable worlds are missing. (shrink)
