The primary aim of this book is to understand how seemings relate to justification and whether some version of dogmatism or phenomenal conservatism can be sustained. It also addresses a number of other issues, including the nature of seemings, cognitive penetration, Bayesianism, and the epistemology of morality and disagreement.

Open-minded people should endorse dogmatism because of its explanatory power. Dogmatism holds that, in the absence of defeaters, a seeming that P necessarily provides non-inferential justification for P. I show that dogmatism provides an intuitive explanation of four issues concerning non-inferential justification. It is particularly impressive that dogmatism can explain these issues because prominent epistemologists have argued that it can’t address at least two of them. Prominent epistemologists also object that dogmatism is absurdly permissive because it allows a seeming to (...) provide justification even if the seeming was caused in some apparently inappropriate way. I conclude by disarming this objection. (shrink)

It is natural to think that many of our beliefs are rational because they are based on seemings, or on the way things seem. This is especially clear in the case of perception. Many of our mathematical, moral, and memory beliefs also appear to be based on seemings. In each of these cases, it is natural to think that our beliefs are not only based on a seeming, but also that they are rationally based on these seemings—at least assuming there (...) is no relevant counterevidence. This piece is an introduction to a volume dedicated to the question of what the connection is between seemings and justified belief: under what conditions, if any, can a seeming justify its content?

Classical acquaintance theory is any version of classical foundationalism that appeals to acquaintance in order to account for non-inferential justification. Such theories are well suited to account for a kind of infallible non-inferential justification. Why am I justified in believing that I’m in pain? An initially attractive (partial) answer is that I’m acquainted with my pain. But since I can’t be acquainted with what isn’t there, acquaintance with my pain guarantees that I’m in pain. What’s less clear is whether, given (...) classical acquaintance theory, it’s possible to have non-inferential justification to believe something false. Classical acquaintance theorists try to make room for such a possibility, but I argue that the attempts of Richard Fumerton, Ali Hasan, and Evan Fales are inadequate. I’ll focus on introspective justification, but similar issues arise for a priori justification as well. (shrink)

Does inferential justification require the subject to be aware that her premises support her conclusion? Externalists tend to answer “no” and internalists tend to answer “yes”. In fact, internalists often hold the strong higher-level requirement that an argument justifies its conclusion only if the subject justifiably believes that her premises support her conclusion. I argue for a middle ground. Against most externalists, I argue that inferential justification requires that one be aware that her premises support her conclusion. Against many internalists, (...) I argue that this higher-level awareness needn’t be doxastic or justified. I also argue that the required higher-level awareness needn’t be caused in some appropriate way, e.g. by a reliable or properly functioning faculty. I suspect that this weaker higher-level requirement is overlooked because, at first glance, it seems absurd to allow nondoxastic, unjustified, and unreliably-caused higher-level awareness to contribute to inferential justification. One of the central goals of this paper is to explain how such weak awareness can make an essential contribution to inferential justification. (shrink)

This book examines the way in which new discoveries about genetic and neuroscience are influencing our understanding of human behaviour. As scientists unravel more about the ways in which genes and the environment work together to shape the development of our brains, their studies have importance beyond the narrow confines of the laboratory. This emerging knowledge has implications for our notions of morality and criminal responsibility. The extent to which "biological determinism" can be used as an explanation for our behaviour (...) is of interest to philosophers reflecting on the free will versus determinism debate. It also has repercussions for the criminal justice system; in courtrooms around the world, defence lawyers are beginning to appeal to genetic and brain imaging data as grounds for finding their clients not guilty. Can a defendant's genes or the structure of his brain be used as an excuse for his behaviour? Is criminality "hardwired"? Is it legitimate to claim "I couldn't help it, my genes made me do it"? This book appeals to anyone interested in the link between behaviour and genetics, the science and philosophy of moral responsibility and/or criminal law. (shrink)

This chapter explores whether and when experience can be evidence. It argues that experiences can be evidence, and that this claim is compatible with just about any epistemological theory. It evaluates the most promising argument for the conclusion that certain experiences (e.g., seeming to see) are always evidence for believing what the experiences represent. While the argument is very promising, one premise needs further defense. The argument also depends on a certain connection between reasonable belief and the first person perspective.

This essay aims to provide a self-contained introduction to time in relativistic cosmology that clarifies both how questions about the nature of time should be posed in this setting and the extent to which they have been or can be answered empirically. The first section below recounts the loss of Newtonian absolute time with the advent of special and general relativity, and the partial recovery of absolute time in the form of cosmic time in some cosmological models. Section II considers (...) the beginning and end of time in a broader class of models in which there is not an analog of Newtonian absolute time. As we will see, reasonable physical assumptions imply that the universe is finite to the past, and Section III turns to consideration of the “beginning” itself. We critically review conventional wisdom that a “singularity” reveals flaws in general relativity and briefly assess ways of avoiding the singularity. (shrink)

On the History and Transmission of Lacanian Psychoanalysis addresses key questions about the history and transmission of Lacan's work in North America through discussions with experienced psychoanalysts (who are also trained psychiatrists, psychologists, and psychotherapists). Chris Vanderwees presents conversations with clinicians about their psychoanalytic formation and about the development of Lacanian psychoanalysis in North America over the past several decades. With oral narrative brought out through the technique of free association, then transcribed and annotated, each discussion is a trace (...) of Vanderwees' encounter with each clinician and the result of collaborative efforts involving speech, writing, translation, and transmission. The conversational tone makes these discussions accessible not only for those already well-versed in Lacan's thinking, but also for anyone discovering his work for the first time. The range of contributions spans both French and English-speaking Canada, the United States, and Mexico. Complemented by On the Theory and Clinic of Lacanian Psychoanalysis, this book of conversations conveys the diversity of historical and pedagogical perspectives on theory and practice as inspired by Lacan's system of thought. It will be of great interest to all psychoanalytic practitioners as well as academics and scholars of psychoanalysis. (shrink)

Experimental philosophers have disagreed about whether "the folk" are intuitively incompatibilists or compatibilists, and they have disagreed about the role of abstraction in generating such intuitions. New experimental evidence using Construal Level Theory is presented. The experiments support the views that the folk are intuitively both incompatibilists and compatibilists, and that abstract mental representations do shift intuitions, but not in a univocal way.

The Oxford Handbook of the History of Physics brings together cutting-edge writing by more than twenty leading authorities on the history of physics from the seventeenth century to the present day. By presenting a wide diversity of studies in a single volume, it provides authoritative introductions to scholarly contributions that have tended to be dispersed in journals and books not easily accessible to the general reader. While the core thread remains the theories and experimental practices of physics, the Handbook contains (...) chapters on other dimensions that have their place in any rounded history. These include the role of lecturing and textbooks in the communication of knowledge, the contribution of instrument-makers and instrument-making companies in providing for the needs of both research and lecture demonstrations, and the growing importance of the many interfaces between academic physics, industry, and the military.

The letters transcribed in this book were written by physicist David Bohm to three close female acquaintances in the period 1950 to 1956. They provide a background to his causal interpretation of quantum mechanics and the Marxist philosophy that inspired his scientific work in quantum theory, probability and statistical mechanics. In his letters, Bohm reveals the ideas that led to his ground breaking book Causality and Chance in Modern Physics. The political arguments as well as the acute personal problems contained (...) in these letters help to give a rounded, human picture of this leading scientist and twentieth century thinker.

Abstract:In this essay I respond to four commentators who participated in a symposium on my book, Reconstructing Pragmatism. Issues that emerge include: Addams’s and Rorty’s mutual commitment to cultivating affective rationality; how Royce and Rorty share an ethical imperative in their philosophy and where both can learn from Alain Locke; what a post-Rortyan pragmatism might look like and the best path toward realizing it; the significance of recovering the serious, unironic Rorty and the limits of weak misreadings; Rorty’s pragmatic maxim; (...) and reflections on how best to sustain the habits and practices of a robust pragmatic tradition and community. In places, for understandable reasons the commentaries stray from the book’s argument about Rorty’s relation to classical pragmatism and address larger issues surrounding Rorty’s work and its broader reception. I don’t respond to all such matters but try to here and there, which hopefully gives what follows a relevance for contemporary pragmatism beyond the book itself. (shrink)

Each day, a countless number of items is sold through online auction sites such as eBay and Ricardo. Though abuse is being reported more and more, transactions seem to be relatively hassle free. A possible explanation for this phenomenon is that the sites’ reputation mechanisms prevent opportunistic behavior. To analyze this issue, we first summarize and extend the mechanisms that affect the probability of sale of an item and its price. We then try to replicate the results as found in (...) four recent papers on online auctions. Our analyses reveal that (1) it makes sense to differentiate between ‘power sellers’ and the less regular users, (2) there are variables that have an effect on sales that are often not controlled for, (3) one should carefully consider how reputation is operationalized, ( 4) neglecting heteroscedastidty in the data can have serious consequences, and (5) there is some support indicating that effects differ across auction sites.

Experimental philosophy is comprised of two broad projects, the negative project and the positive project, each of which is a response to a kind of armchair use of intuitions. I examine two examples of the negative project-the analysis of knowledge and the theory of reference-and two examples of the positive project-free will and intentional action-and review criticisms of each example. I show how the criticisms can be met and argue that even if they could not have been met, experimental philosophy (...) raises important questions about methodology, opening the door on new questions and new ways of looking at old questions. For that reason, experimental philosophy as a movement is robust and full of potential. (shrink)

A timely, well-grounded analysis that reveals an inconvenient truth: we can't save capitalism and save the planet.

From gender and identity to welfare and consumerism, sociology is the study of how societies are organized and what helps them function or go wrong. Questions posed include: What is my "tribe"? Why do people commit crimes? Who decides if someone has a mental illness? What's work for? Does aid do any good? Heads Up Sociology explores these fascinating questions and more.

Chris Turner argues that Stephen Harper's attack on basic science, science communication, environmental regulations, and the environmental NGO community is the most vicious assault ever waged by a Canadian government on the fundamental principles of the Enlightenment. From the closure of Arctic research stations as oil drilling begins in the High Arctic to slashed research budgets in agriculture, dramatic changes to the nation's fisheries policy, and the muzzling of government scientists, Harper's government has effectively dismantled Canada's long-standing scientific tradition. (...) Drawing on interviews with scientists whose work has been halted by budget cuts and their colleagues in an NGO community increasingly treated as an enemy of the state, The War on Science paints a vivid and damning portrait of a government that has abandoned environmental stewardship and severed a national commitment to the objective truth of basic science as old as Canada itself.

It's easy and reflexive to view our online presence as fake, to see the internet as a space we enter when we aren't living our real, offline lives. Yet so much of who we are and what we do now happens online, making it hard to know which parts of our lives are real. IRL, Chris Stedman's personal and searing exploration of authenticity in the digital age, shines a light on how age-old notions of realness--who we are and where (...) we fit in the world--can be freshly understood in our increasingly online lives. Stedman offers a different way of seeing the supposed split between our online and offline selves: the internet and social media are new tools for understanding and expressing ourselves, and the not-always-graceful ways we use these tools can reveal new insights into far older human behaviors and desires. IRL invites us to consider how we use the internet to fulfill the essential human need to feel real--a need many of us once met in institutions, but now seek to do on our own, online--as well as the ways we edit or curate ourselves for digital audiences. The digital search for meaning and belonging presents challenges, Stedman suggests, but also myriad opportunities to become more fully human. In the end, he makes a bold case for embracing realness in all of its uncertainty, online and off, even when it feels risky. -- from jacket. (shrink)

This paper articulates and defends an underexplored account of faith—the perspectival account of faith—according to which faith is a value-oriented perspective on the world toward which the subject has a pro-attitude. After describing this account of faith and outlining what it is to have faith on the perspectival account, I show that the perspectival account meets methodological criteria for an account of faith. I then show that this account of faith can be used to unify various faith locutions: having faith (...) that p (propositional faith), having faith in something (attitudinal faith), being a person of faith (global faith), articles of faith (creedal faith), and acts of faith (praxical faith). Finally, since the perspectival account of faith is a cognitive account of faith, I defend the perspectival view against objections to cognitive accounts of faith. (shrink)

Perceptual dogmatism is a prominent theory in epistemology concerning the relationship between perceptual experience and reasonable belief. It holds that, in the absence of counterevidence, it is reasonable to believe what your perceptual experience tells you. Thus, if you are not aware of your experience’s casual history, then it doesn’t matter. Critics object that the causal history does matter: when a perceptual experience is caused in certain ways, it is unreasonable to trust what it tells you. These objections regularly appeal (...) to cognitive penetration and biased searches for evidence. Given the myriad accounts of what covert attention is, one wonders (at least I wondered) if biased patterns of covert attention could raise a new objection to dogmatism. I argue that, while covert selection might raise various problems for dogmatism, none of them are new. This is good news for dogmatism, because the fewer distinct problems it faces, the more likely it can resolve them all. (shrink)

This innovative text addresses the lack of literature regarding intersectional approaches to psychoanalysis, underscoring the importance of thinking through race, class, and gender within psychoanalytic theory and practice. The book tackles the widespread perception of psychoanalysis today as a discipline detached from the progressive ideals of social responsibility, institutional psychotherapy, and community mental health. Bringing together a range of international contributions, the collection explores issues of class, politics, oppression, and resistance within the field of psychoanalysis in cultural, theoretical, and clinical (...) contexts. It shows how, in contrast to this misperception, psychoanalysis has been attentive to these ideals from its origins, as well as demonstrating how it continues to be relevant today, through wide-ranging conceptual discussions of the anti-globalisation, Black Lives Matter and #MeToo movements. Written in an accessible style, Psychoanalysis, Politics, Oppression and Resistance will be essential reading for practicing psychoanalysts as well as academics and students in a range of humanities and social sciences fields.

Cutting-edge essays on theory, aesthetics, and human and nonhuman ontology.

Recent clinical trials show that psychedelics such as LSD and psilocybin can be given safely in controlled conditions, and can cause lasting psychological benefits with one or two administrations. Supervised psychedelic sessions can reduce symptoms of anxiety, depression, and addiction, and improve well-being in healthy volunteers, for months or even years. But these benefits seem to be mediated by "mystical" experiences of cosmic consciousness, which prompts a philosophical concern: do psychedelics cause psychological benefits by inducing false or implausible beliefs about (...) the metaphysical nature of reality? This book is the first scholarly monograph in English devoted to the philosophical analysis of psychedelic drugs. Its central focus is the apparent conflict between the growing use of psychedelics in psychiatry and the philosophical worldview of naturalism. Within the book, Letheby integrates empirical evidence and philosophical considerations in the service of a simple conclusion: this "Comforting Delusion Objection" to psychedelic therapy fails. While exotic metaphysical ideas do sometimes come up, they are not, on closer inspection, the central driver of change in psychedelic therapy. Psychedelics lead to lasting benefits by altering the sense of self, and changing how people relate to their own minds and lives-not by changing their beliefs about the ultimate nature of reality. The upshot is that a traditional conception of psychedelics as agents of insight and spirituality can be reconciled with naturalism (the philosophical position that the natural world is all there is). Controlled psychedelic use can lead to genuine forms of knowledge gain and spiritual growth-even if no Cosmic Consciousness or transcendent divine Reality exists. Philosophy of Psychedelics is an indispensable guide to the literature for researchers already engaged in the field of psychedelic psychiatry, and for researchers-especially philosophers-who want to become acquainted with this increasingly topical field.

What is the nature of deep disagreement? In this paper, I consider two similar albeit seemingly rival answers to this question: the Wittgensteinian theory, according to which deep disagreements are disagreements over hinge propositions, and the fundamental epistemic principle theory, according to which deep disagreements are disagreements over fundamental epistemic principles. I assess these theories against a set of desiderata for a satisfactory theory of deep disagreement, and argue that while the fundamental epistemic principle theory does better than the Wittgensteinian (...) theory on this score, the fundamental epistemic principle theory nevertheless struggles to explain the variety of deep disagreement.

Users of psychedelic drugs often report that their sense of being a self or ‘I’ distinct from the rest of the world has diminished or altogether dissolved. Neuroscientific study of such ‘ego dissolution’ experiences offers a window onto the nature of self-awareness. We argue that ego dissolution is best explained by an account that explains self-awareness as resulting from the integrated functioning of hierarchical predictive models which posit the existence of a stable and unchanging entity to which representations are bound. (...) Combining recent work on the ‘integrative self' and the phenomenon of self-binding with predictive processing principles yields an explanation of ego dissolution according to which self-representation is a useful Cartesian fiction: an ultimately false representation of a simple and enduring substance to which attributes are bound which serves to integrate and unify cognitive processing across levels and domains. The self-model is not a mere narrative posit, as some have suggested; it has a more robust and ubiquitous cognitive function than that. But this does not mean, as others have claimed, that the self-model has the right attributes to qualify as a self. It performs some of the right kinds of functions, but it is not the right kind of entity. Ego dissolution experiences reveal that the self-model plays an important binding function in cognitive processing, but the self does not exist. (shrink)

This article argues for a revised best system account of laws of nature. David Lewis’s original BSA has two main elements. On the one hand, there is the Humean base, which is the totality of particular matters of fact that obtain in the history of the universe. On the other hand, there is what I call the ‘nomic formula’, which is a particular operation that gets applied to the Humean base in order to output the laws of nature. My revised (...) account focuses on this latter element of the view. Lewis conceives of the nomic formula as a balance of simplicity and strength, but I argue that this is a mistake. Instead, I motivate and develop a different proposal for the standards that figure into the nomic formula, and I suggest a rationale for why these should be the correct standards. Specifically, I argue that the nomic formula should be conceived as a collection of desiderata designed to generate principles that are predictively useful to creatures like us. The resulting view—which I call the ‘best predictive system’ account of laws—is thus able to explain why scientists are interested in discovering the laws, and it also gives rise to laws with the sorts of features that we find in actual scientific practice 1Introduction2The LOPP3A Problem with Lewis's Formula4A Pragmatic Account of the Nomic Formula 4.1Informative dynamics4.2Wide applicability4.3Spatial locality4.4Temporal locality4.5Spatial, temporal, and rotational symmetries4.6Predictively useful properties4.7Simplicity4.8Recap5 Conclusion.

This paper explores the application of hinge epistemology to deep disagreement. Hinge epistemology holds that there is a class of commitments—hinge commitments—which play a fundamental role in the structure of belief and rational evaluation: they are the most basic general ‘presuppositions’ of our world views which make it possible for us to evaluate certain beliefs or doubts as rational. Deep disagreements seem to crucially involve disagreements over such fundamental commitments. In this paper, I consider pessimism about deep disagreement, the thesis (...) that such disagreements are rationally irresolvable, and ask whether the Wittgensteinian account of deep disagreement—according to which such disagreements are disagreements over hinge commitments—provides adequate support for pessimism. I argue that the answer to this question depends on what hinge commitments are and what our epistemic relation to them is supposed to be. I argue for two core claims. First, that non-epistemic theories of hinge commitments provide adequate support for pessimism. Nevertheless, such theories have highly implausible consequences in the context of deep disagreement. Secondly, at least one epistemic theory of hinge commitments, the entitlement theory, permits optimism about such disagreements. As such, while hinge epistemology is mainly pessimistic about deep disagreement, it doesn’t have to be. (shrink)

Some disagreements concern our most fundamental beliefs, principles, values, or worldviews, such as those about the existence of God, society and politics, or the trustworthiness of science. These are ‘deep disagreements’. But what exactly are deep disagreements? This paper critically overviews theories of deep disagreement. It does three things. First, it explains the differences between deep and other kinds of disagreement, including peer, persistent, and widespread disagreement. Second, it critically overviews two mainstream theories of deep disagreement, the Wittgensteinian account and (...) the Fundamental Epistemic Principle account, before introducing a Hybrid account. Finally, it explores the notion that deep disagreements can be deeper than others. (shrink)

Many nongovernmental forms of business regulation aim at reducing ethical violations in commerce. We argue that such nongovernmental ethics standards, while often laudable, raise their own ethical challenges. In particular, when such standards place burdens upon vulnerable market participants (often, though not always, SMEs), they do so without the backing of traditional legitimate political authority. We argue that this constitutes a structural analogy to wars of humanitarian intervention. Moreover, we show that, while some harms imposed by such standards are desirable, (...) others are best thought of as a form of collateral damage. We thus look at the well-developed literature on just war theory for inspiration and find that the principles of jus ad bellum and jus in bello contain many insights that can be fruitfully adapted to the case of nongovernmental standard-setting. Consequently, we propose the Ius ad Normam—a set of principles that should guide would-be standard-setters in assessing whether imposing those burdens is ethically justifiable in particular cases. We also discuss how powerful multinational businesses often act simultaneously as standard-takers and standard-setters and explore the normative implications of this dual role. (shrink)

The second edition of Doing Ethics in Media continues its mission of providing an accessible but comprehensive introduction to media ethics, with a theoretical grounding in moral philosophy, to help students think clearly and systematically about dilemmas in the rapidly changing media environment. Each chapter highlights specific considerations, cases, and practical applications for the fields of journalism, advertising, digital media, entertainment, public relations, and social media. Six fundamental decision-making questions - the "5Ws and H" around which the book is organized (...) - provide a path for students to articulate the issues; understand applicable law and ethics codes; consider the needs of stakeholders; work through conflicting values; integrate philosophic principles; and pose a "test of publicity." Students are challenged to be active ethical thinkers through the authors' reader-friendly style and use of critical early-career examples. While most people will change careers several times during their lives, all of us are life-long media consumers, and Doing Ethics in Media prepares readers for that task. Doing Ethics in Media is aimed at undergraduate and graduate students studying media ethics in mass media, journalism, and media studies. It also serves students in rhetoric, popular culture, communication studies, and interdisciplinary social sciences. The book's companion website-doingethicsin.media, or www.doingmediaethics.com-provides continuously updated real-world media ethics examples and collections of essays from experts and students. The site also hosts ancillary materials for students and for instructors, including a test bank and instructor's manual. (shrink)

The moral enhancement of humans by biological or genetic means has recently been urged as a response to the pressing concerns facing human civilization. In this paper, I argue that proponents of biological moral enhancement have misrepresented the facts of human moral psychology. As a result, the likely effectiveness of traditional methods of moral enhancement has been underestimated, relative to biological or genetic means. I review arguments in favor of biological moral enhancement and argue that the complexity of moral psychology (...) raises serious problems for such interventions. I offer a programmatic sketch of the ways in which our improved understanding of moral psychology can help facilitate more traditional methods of moral enhancement. I conclude that the best response to the dangers faced by human civilization is the continued use of traditional methods of moral enhancement and the use of our improved understanding of moral psychology to further refine and develop these methods.
