David Lewis (1941-2001) was Class of 1943 University Professor of Philosophy at Princeton University. His contributions spanned philosophical logic, philosophy of language, philosophy of mind, philosophy of science, metaphysics, and epistemology. In On the Plurality of Worlds, he defended his challenging metaphysical position, "modal realism." He was also the author of the books Convention, Counterfactuals, Parts of Classes, and several volumes of collected papers.

Here the philosopher and physicist David Z Albert argues, among other things, that the difference between past and future can be understood as a mechanical phenomenon of nature and that quantum mechanics makes it impossible to present the entirety of what can be said about the world as a narrative of “befores” and “afters.”.

In _Panpsychism in the West_, the first comprehensive study of the subject, David Skrbina argues for the importance of panpsychism -- the theory that mind exists, in some form, in all living and nonliving things -- in consideration of the nature of consciousness and mind. Despite the recent advances in our knowledge of the brain and the increasing intricacy and sophistication of philosophical discussion, the nature of mind remains an enigma. Panpsychism, with its conception of mind as a general (...) phenomenon of nature, uniquely links being and mind. More than a theory of mind, it is a meta-theory -- a statement about theories of mind rather than a theory in itself. Panpsychism can parallel almost every current theory of mind; it simply holds that, no matter how one conceives of mind, such mind applies to all things. In addition, panpsychism is one of the most ancient and enduring concepts of philosophy, beginning with its pre-historical forms, animism and polytheism. Its adherents in the West have included important thinkers from the very beginning of Greek philosophy through the sixteenth and seventeenth centuries to the present. Skrbina argues that panpsychism is long overdue for detailed treatment, and with this book he proposes to add impetus to the discussion of panpsychism in serious philosophical inquiries. After a brief discussion of general issues surrounding philosophy of mind, he traces the panpsychist views of specific philosophers, from the ancient Greeks and early Renaissance naturalist philosophers through the likes of William James, Josiah Royce, and Charles Sanders Peirce -- always with a strong emphasis on the original texts. In his concluding chapter, "A Panpsychist World View," Skrbina assesses panpsychist arguments and puts them in a larger context. By demonstrating that there is panpsychist thinking in many major philosophers, Skrbina offers a radical challenge to the modern worldview, based as it is on a mechanistic cosmos of dead, insensate matter. _Panpsychism in the West _will be the standard work on this topic for years to come.

Throughout the darkest moments of human history, evildoers have convinced communities to turn on groups that are regarded as in some way other and, by starting to think of them as less than human, persecute or even eliminate them. We can all recognize the unfathomable evils of dehumanization in slavery, the Holocaust, the Rwandan genocide, and the Jim Crow South, but we are not free from its power today. With climate change and political upheaval driving millions of refugees worldwide to (...) leave their homes, we are likely to see more and more of this ugly and persistent phenomenon. What are we to do? Drawing on his deep and wide-ranging knowledge of the history, psychology, and politics of dehumanization, David Livingstone Smith shows us how to recognize it and how to fight back. (shrink)

More attention has been devoted to providing evolutionary accounts of the development of beliefs, or belief-like states, than for desires or preferences. Here I articulate and defend an evolutionary rationale for the development of psychologically real preference states. Preferences token or represent the expected values available actions given discriminated states of world and agent. The argument is an application of the ‘environmental complexity thesis’ found in Godfrey-Smith and Sterelny, although my conclusions differ from Sterelny’s. I argue that tokening expected utilities (...) can, under specified general conditions, be a powerful design solution to the problem of efficiently allocating the capacities of an agent. Preferences are for efficient action selection, and count as a ‘fuel for success’ in the sense urged by Godfrey-Smith for true beliefs. They will tend to be favoured by selection when environments are complex in ways that matter to an organism, and when organisms have large behavioural repertoires with heterogeneous returns and costs.The rationale suggested here is conditional, especially on contingencies in what design options are available to selection and on trade-offs associated with the costs of generating and processing representations of value. The unqualified efficiency rationale for preferences suggests that organisms should represent expected utilities in a comprehensive and consistent way, but none of them do. In the final stages of the paper I consider some of the ways design trade-offs compromise the implementation of preferences in organisms that have them. (shrink)

Stawarczyk, Bezdek, and Zacks offer neuroscience evidence for a midline default network core, which appears to coordinate internal, top‐down mentation with externally‐triggered, bottom‐up attention in a push‐pull relationship. The network may enable the flexible pursuance of thoughts tuned into or detached from the current environment.

Aware that the representational thesis is more plausible for the attitudinal than for the phenomenal, Dretske courageously focuses on sensory experience, where progress in our philosophical understanding of the mental has lagged. His view, essentially, is that what makes any mental state what it is is not so much what it's like as what it's about.

Pierre Bourdieu is one of the world's most important social theorists and is also one of the great empirical researchers in contemporary sociology. However, reading Bourdieu can be difficult for those not familiar with the French cultural context, and until now a comprehensive introduction to Bourdieu's oeuvre has not been available. David Swartz focuses on a central theme in Bourdieu's work—the complex relationship between culture and power—and explains that sociology for Bourdieu is a mode of political intervention. Swartz clarifies (...) Bourdieu's difficult concepts, noting where they have been misinterpreted by critics and where they have fallen short in resolving important analytical issues. The book also shows how Bourdieu has synthesized his theory of practices and symbolic power from Durkheim, Marx, and Weber, and how his work was influenced by Sartre, Levi-Strauss, and Althusser. _Culture and Power_ is the first book to offer both a sympathetic and critical examination of Bourdieu's work and it will be invaluable to social scientists as well as to a broader audience in the humanities.

In this book, David Stump traces alternative conceptions of the a priori in the philosophy of science and defends a unique position in the current debates over conceptual change and the constitutive elements in science. Stump emphasizes the unique epistemological status of the constitutive elements of scientific theories, constitutive elements being the necessary preconditions that must be assumed in order to conduct a particular scientific inquiry. These constitutive elements, such as logic, mathematics, and even some fundamental laws of nature, (...) were once taken to be a priori knowledge but can change, thus leading to a dynamic or relative a priori. Stump critically examines developments in thinking about constitutive elements in science as a priori knowledge, from Kant’s fixed and absolute a priori to Quine’s holistic empiricism. By examining the relationship between conceptual change and the epistemological status of constitutive elements in science, Stump puts forward an argument that scientific revolutions can be explained and relativism can be avoided without resorting to universals or absolutes.

Analyses of dispositional ascriptions in terms of conditional statements famously confront the problems of finks and masks. We argue that conditional analyses of dispositions, even those tailored to avoid finks and masks, face five further problems. These are the problems of: (i) Achilles' heels, (ii) accidental closeness, (iii) comparatives, (iv) explaining context sensitivity, and (v) absent stimulus conditions. We conclude by offering a proposal that avoids all seven of these problems.

Indexicals are linguistic expressions whose reference shifts from context to context: some paradigm examples are ‘I’, ‘here’, ‘now’, ‘today’,‘he’, ‘she’, and ‘that’. Two speakers who utter a single sentence that contains an indexical may say different things. For instance, Fred and Wilma say different things when they utter the sentence ‘I am female’. Many philosophers (following David Kaplan 1989a) hold that indexicals have two sorts of meaning. The first sort of meaning is often called ‘character’ or ‘linguistic meaning’; the (...) second sort is often called ‘content’. Using this terminology, we can say that the word ‘I’ has a single character (or linguistic meaning), but has different contents in different contexts. (shrink)

David Albert claims that classical electromagnetic theory is not time reversal invariant. He acknowledges that all physics books say that it is, but claims they are ``simply wrong" because they rely on an incorrect account of how the time reversal operator acts on magnetic fields. On that account, electric fields are left intact by the operator, but magnetic fields are inverted. Albert sees no reason for the asymmetric treatment, and insists that neither field should be inverted. I argue, to (...) the contrary, that the inversion of magnetic fields makes good sense and is, in fact, forced by elementary geometric considerations. I also suggest a way of thinking about the time reversal invariance of classical electromagnetic theory -- one that makes use of the invariant (four-dimensional) formulation of the theory -- that makes no reference to magnetic fields at all. It is my hope that it will be of interest in its own right, Albert aside. It has the advantage that it allows for arbitrary curvature in the background spacetime structure, and is therefore suitable for the framework of general relativity. (The only assumption one needs is temporal orientability.). (shrink)

In this new introduction to a classic philosophical text, David Stern examines Wittgenstein's Philosophical Investigations. He gives particular attention to both the arguments of the Investigations and the way in which the work is written, and especially to the role of dialogue in the book. While he concentrates on helping the reader to arrive at his or her own interpretation of the primary text, he also provides guidance to the unusually wide range of existing interpretations, and to the reasons (...) why the Investigations have inspired such a diversity of readings. Following closely the text of the Investigations and meant to be read alongside it, this survey is accessible to readers with no previous background in philosophy. It is well-suited to university-level courses on Wittgenstein, but can also be read with profit by students in other disciplines. (shrink)

This book aims to discuss probability and David Hume's inductive scepticism. For the sceptical view which he took of inductive inference, Hume only ever gave one argument. That argument is the sole subject-matter of this book. The book is divided into three parts. Part one presents some remarks on probability. Part two identifies Hume's argument for inductive scepticism. Finally, the third part evaluates Hume's argument for inductive scepticism. Hume's argument that induction must be either deductively valid or circular because (...) based on experience neglects the possibility that it is an argument of non-deductive logic (logical probability, in the sense of Keynes).

Do psychological traits predict philosophical views? We administered the PhilPapers Survey, created by David Bourget and David Chalmers, which consists of 30 views on central philosophical topics (e.g., epistemology, ethics, metaphysics, philosophy of mind, and philosophy of language) to a sample of professional philosophers (N = 314). We extended the PhilPapers survey to measure a number of psychological traits, such as personality, numeracy, well-being, lifestyle, and life experiences. We also included non-technical ‘translations’ of these views for eventual use (...) in other populations. We found limited to no support for the notion that personality or demographics predict philosophical views. We did, however, find that some psychological traits were predictive of philosophical views, even after strict correction for multiple comparisons. Findings include: higher interest in numeracy predicted physicalism, naturalism, and consequentialism; lower levels of well-being and higher levels of mental illness predicted hard determinism; using substances such as psychedelics and marijuana predicted non-realist and subjectivist views of morality and aesthetics; having had a transformative or self-transcendent experience predicted theism and idealism. We discuss whether or not these empirical results have philosophical implications, while noting that 68% of our sample of professional philosophers indicated that such findings would indeed have philosophical value.

Several alleged counterexamples to the definition of ‘intrinsic’ proposed in Rae Langton and David Lewis, ‘Defining “Intrinsic”’, are unconvincing. Yet there are reasons for dissatisfaction, and room for improvement. One desirable change is to raise the standard of non-disjunctiveness, thereby putting less burden on contentious judgements of comparative naturalness. A second is to deal with spurious independence by throwing out just the disjunctive troublemakers, instead of throwing out disjunctive properties wholesale, and afterward reinstating those impeccably intrinsic disjunctive properties that (...) are not troublemakers. A third, suggested by Brian Weatherson, would be to invoke the general principle that the intrinsic and the extrinsic characters of things are independent, rather than relying just on one special case of this principle; but it is none too obvious how to do this.

In response to a recent argument by David Bloor, I argue that denying absolutes does not necessarily lead to relativism, that one can be a fallibilist without being a relativist. At issue are the empirical natural sciences and what might be called “framework relativism”, that is, the idea that there is always a conceptual scheme or set of practices in use, and all observations are theory-laden relative to the framework. My strategy is to look at the elements that define (...) a relativist stance and show where the pragmatic fallibilist disagrees. Defending the pragmatic notion of experience will be central, given that relativists reject the idea that experience can play a role in objectively justifying belief. We can reject all absolutes and start from the premise that everything is historical, contingent, and situated. One of the lessons of pragmatism is that universal and fixed principles are not necessary for objective knowledge. (shrink)

Moses Mendelssohn (1729-1786) was the premier Jewish thinker of his day and one of the best-known figures of the German Enlightenment, earning the sobriquet 'the Socrates of Berlin'. He was thoroughly involved in the central issue of Enlightenment religious thinking: the inevitable conflict between reason and revelation in an age contending with individual rights and religious toleration. He did not aspire to a comprehensive philosophy of Judaism, since he thought human reason was limited, but he did see Judaism as compatible (...) with toleration and rights. David Sorkin offers a close study of Mendelssohn's complete writings, treating the German, and the often-neglected Hebrew writings, as a single corpus and arguing that Mendelssohn's two spheres of endeavour were entirely consistent.

Geographies of Exclusion identifies forms of social and spatial exclusion and subsequently examines the fate of knowledge of space and society which has been produced by members of excluded groups. Evaluating writing on urban society by women and black writers, David Sibley asks why such work is neglected by the academic establishment, suggesting that both the practices which result in the exclusion of minorities and those which result in the exclusion of knowledge have important implications for theory and method (...) in human geography. Drawing on a range of ideas from social anthropology, feminist theory, sociology, human geography and psychoanalysis, this book presents a fresh approach to geographical theory, highlighting the tendency of powerful groups to "purify" space and to view minorites as defiled and polluting, and exploring the nature of "difference" and the production of knowledge.

Ways of the Hand tells the story of how David Sudnow learned to improvise jazz on the piano. Because he had been trained as an ethnographer and social psychologist, Sudnow was attentive to what he experienced in ways that other novice pianists are not. The result, first published in 1978 and now considered by many to be a classic, was arguably the finest and most detailed account of skill development ever published.Looking back after more than twenty years, Sudnow was (...) struck by the extent to which he had allowed his academic background to shape the book's language. He realized that he could now do a much better job of describing his experiences in a way that would not require facility with formal social science and philosophical discourse. The result is a revised version of the book that carries the same intellectual energy as the original but is accessible to a much wider audience. (shrink)

[A slightly revised version of this paper has been accepted by the BJPS] More attention has been devoted to providing evolutionary scenarios accounting for the development of beliefs, or belief-like states, than for desires or preferences. Here I articulate and defend an evolutionary rationale for the development of psychologically real preference states. Preferences token or represent the expected values of discriminated states, available actions, or action-state pairings. The argument is an application the ‘environmental complexity thesis’ found in Godfrey-Smith and Sterelny, (...) although my conclusions differ from Sterelny’s. I argue that tokening expected utilities can, under specified general conditions, be a powerful design solution to the problem of allocating the capacities of an agent in an efficient way. Preferences are for efficient action selection, and are a ‘fuel for success’ in the sense urged by Godfrey-Smith for true beliefs. They will tend to be favoured by selection when environments are complex in ways that matter to an organism, and when organisms have rich behavioural repertoires with heterogenous returns and costs. The rationale suggested here is conditional, especially on contingencies in what design options are available to selection and on trade-offs associated with the costs of generating and processing representations of value. The unqualified efficiency rationale for preferences suggests that organisms should represent expected utilities in a comprehensive and consistent way, but none of them do. In the final stages of the paper I consider some of the ways in which design trade-offs compromise the implementation of preferences in organisms that have them. (shrink)

David Webster explores the notion of desire as found in the Buddhist Pali Canon. Beginning by addressing the idea of a 'paradox of desire', whereby we must desire to end desire, the varieties of desire that are articulated in the Pali texts are examined. A range of views of desire, as found in Western thought are presented as well as Hindu and Jain approaches. An exploration of the concept of ditthi (view or opinion) is also provided, exploring the way (...) in which 'holding views' can be seen as analogous to the process of desiring. Other subjects investigated include the mind-body relationship, the range of Pali terms for desire, and desire's positive spiritual value. A comparative exploration of the various approaches completes the work. (shrink)

A striking feature of the latest version of Dennett’s ‘big picture’ of the evolution of life and mind is frequent reference to ‘affordances’. An affordance is, roughly, a possibility for action for a creature in an environment. Given more than one possibility for action, a good question is: what will the creature actually do? I argue that affordances pose a problem of selection, and that a good general solution to this problem of mind-design is to implement a system of preferences.

Many guidelines and commentators endorse the view that clinical research is ethically acceptable only when it has social value, in the sense of collecting data which might be used to improve health. A version of this social value requirement is included in the Declaration of Helsinki and the Nuremberg Code, and is codified in many national research regulations. At the same time, there have been no systematic analyses of why social value is an ethical requirement for clinical research. Recognizing this (...) gap in the literature, recent articles by Alan Wertheimer and David Resnik argue that the extant justifications for the social value requirement are unpersuasive. Both authors conclude, contrary to almost all current guidelines and regulations, that it can be acceptable across a broad range of cases to conduct clinical research which is known prospectively to have no social value. The present article assesses this conclusion by critically evaluating the ethical and policy considerations relevant to the claim that clinical research must have social value. This analysis supports the standard view that social value is an ethical requirement for the vast majority of clinical research studies and should be mandated by applicable guidelines and policies.

In (2001), (2003), and elsewhere, Ted Sider presents two arguments concerning the existential quantifier which are justly central to the recent discussion of metaontology. What we will call Sider's indeterminacy argument is an attempted reductio of the suggestion that the existential quantifier might be semantically indeterminate. What we will call Sider's naturalness argument is an argument for the claim that the semantic value of the existential quantifier is the most eligible existence-like meaning there is, à la David Lewis' eligibility (...) theory of meaning. We will argue that these arguments cannot be jointly maintained: Sider must give up at least one. Before arguing this, we will present Sider's two arguments in a bit more detail, and discuss their relationship. A few remarks on the broader significance of our conclusions are in order at the outset. One may think that since one successful argument for a given conclusion is sufficient the point that Sider's arguments cannot both work is purely academic. But we think that Sider's two arguments at bottom reflect different ways of thinking about metaphysics. Moreover, we think that it is only the naturalness argument that promises to deliver all that Sider wants when it comes to metaontology, and it is only the indeterminacy argument that promises to deliver all that Sider wants when it comes to ontology.

David Kaplan distinguishes between character and content in his theory of demonstratives and indexicals.

Rae Langton and Jennifer Hornsby provide accounts of how pornography silences women by appealing to J.L. Austin's account of speech-acts. Since their accounts focus only on instances of silencing where the hearer does not grasp the type of speech-act the speaker intends to perform, their accounts of silencing do not generalize to explain silencing that arises from what Miranda Fricker calls “testimonial injustice.” I argue that silencing arising from testimonial injustice can only be explained by what we shall call the (...) dialectical account of assertion, according to which assertion is the undertaking of a commitment in reasoned discourse. In doing so, I show that accounts of assertion based on speakers' intentions, proposals to common ground, and constitutive norms do not provide the necessary framework to explain silencing within the context of testimonial injustice. Having shown the strength of the dialectical account in explaining silencing, I conclude that the dialectical account also provides a way to remedy some instances of silencing arising from testimonial injustice providing further evidence that the dialectical account is the correct account of assertion.

We explore success drivers of reward-based crowdfunding for poverty alleviation in China. The results from our econometric modeling using data from 4375 reward-based crowdfunding campaigns suggest that poverty alleviation campaigns, as compared to ordinary ones, benefit from higher funded amounts, larger backer numbers, and greater success rates. The results also suggest that poverty alleviation campaigns perform better when the products sold originate from poorer (as compared to wealthier) regions and when price premiums are lower (as compared to higher). We corroborate (...) important findings from the field study with an experimental study, showing that the consumer’s feeling of warm glow accounts for the positive effects of poverty alleviation campaigns (as compared to ordinary) campaigns. We expand the applications of warm-glow theory into the context of reward-based crowdfunding campaigns for poverty alleviation and offer new insights into success drivers of such campaigns. (shrink)

German Jewish philosopher Moses Mendelssohn was one of the most influential thinkers of the Enlightenment. Until now, attention was focused on Mendelssohn’s German works—such as his groundbreaking _Jerusalem—_which have been duly translated into English.

The effect of concurrent movement on incidental versus intentional statistical learning was examined in two experiments. In Experiment 1, participants learned the statistical regularities embedded within familiarization stimuli implicitly, whereas in Experiment 2 they were made aware of the embedded regularities and were instructed explicitly to learn these regularities. Experiment 1 demonstrated that while the control group were able to learn the statistical regularities, the resistance-free cycling group and the exercise group did not demonstrate learning. This is in contrast with (...) the findings of Experiment 2, where all three groups demonstrated significant levels of learning. The results suggest that the movement demands, rather than the physiological stress, interfered with statistical learning. We suggest movement activates the striatum, which is not only responsible for motor control but also plays a role in incidental learning. (shrink)

In his thoughtful defence of very modest moral enhancement, David DeGrazia1 makes the following assumption: ‘Behavioural improvement is highly desirable in the interest of making the world a better place and securing better lives for human beings and other sentient beings’. Later in the paper, he gives a list of some psychological characteristics that ‘all reasonable people can agree … represent moral defects’. I think I am a reasonable person, and I agree that most if not all items on (...) the lists do represent moral defects—I certainly would regard them as such in a close family member or friend. But if I were in the business of ‘making the world a better place and securing better lives for human beings and other sentient beings’, I would hesitate to prescribe moral enhancement for everyone with these acknowledged defects. A lot of good work, from removing tumours to negotiating treaties, may be best done by people with serious moral defects.For a simple consequentialist, a moral defect is just a trait that tends to make the world a worse place. Not being a consequentialist, I think that moral defects should be identified independently of their tendency to produce worse outcomes. For this reason, I think it's necessary to qualify DeGrazia's starting assumption—I think behavioural improvement may sometimes be undesirable if our goal is to make the world a better place. My reasons will be familiar to readers of Bernard Williams.As …. (shrink)

Ramseyan humility is the thesis that we cannot know which properties realize the roles specified by the laws of completed physics. Lewis seems to offer a sceptical argument for this conclusion. Humean fundamental properties can be permuted as to their causal roles and distribution throughout spacetime, yielding alternative possible worlds with the same fundamental structure as actuality, but at which the totality of available evidence is the same. On the assumption that empirical knowledge requires evidence, we cannot know which of (...) these worlds is actual. However, Lewis also appeals to a range of familiar semantic principles when framing his argument, which leads some authors to suppose that he can also plausibly be interpreted as offering a purely semantic argument for humility in addition. In this paper I grant that these arguments are Lewisian, but argue that Lewis is also committed to a theory of mind that licenses a purely metaphysical argument for humility based on the idea that mental properties supervene on fundamental structure. Given that knowing which x is the F requires knowing that a is the F, the supposition that we could come to know which properties actually occupy the fundamental roles entails differences in mental properties between worlds with the same fundamental structure, violating supervenience. Humility follows right away, without any further epistemic or semantic principles. This argument is immune to almost every way of rebutting the sceptical and semantic arguments; conversely, almost every way of rebutting the metaphysical argument tells equally against the others.

Bioethics, once a four-letter word in the private sector, is now an integral part of the decisionmaking process of biotechnology and pharmaceutical companies. And bioethicists, once confined to the classroom and limited to abstract, philosophical discussions about what is right and wrong in medicine and medical research, now play an important role in the practical implementation of ethical boundaries. Bioethicists increasingly are hired by biomedical companies as consultants to highlight and help resolve complex ethical issues that arise in the companies’ (...) normal business practices. Whether motivated by profit, reputation, or a genuine desire to act morally, these companies are willing to pay bioethicists substantial consultation fees for their “expert” opinions. This fairly recent phenomenon has caused some to be concerned about the potential for bioethicists to encounter conflicts of interests. Specifically, many critics of this new relationship between bioethicists and the private sector “are concerned about the appropriateness of ethicists who should have broader interests, such as concerns about social justice, serving clients whose primary interest is profit-maximizing.”.

Locke thought it was a necessary truth that no two material bodies could be in the same place at the same time. Leibniz wasn't so sure. This paper sides with Leibniz.
