I develop a broadly reliabilist theory of non-ideal epistemic rationality and argue that if it is correct we should reject the recently popular idea that the standards of non-ideal epistemic rationality are mere social conventions.

§1.1 What m otivated the perpetrators of the holocaust? Christopher Browning and Daniel Goldhagen differ in their analysis of Reserve Police Battalion 101 (Browning 1992, Goldhagen 1996). The battalion consisted of around 500 ‘ordinary’ Germ ans who, during the period 1942-44, killed around 40,000 Jews and who deported as m any to the death cam ps. Browning and Goldhagen differ over the m otivation wit h which the m en killed. I want to com m ent on a central aspect (...) of this debate. (shrink)

Corporations are spending a substantial and increasing amount of money on corporate social responsibility. However, little is known about the effects on key stakeholders of these activities. This study investigates if CSR activities have an effect on employees’ affective commitment. Two models test to what extent employees’ CSR perception, involvement in decision processes, and demographic variables are related to their AC relative to their perception of positive organizational support. The analysis is based on a sample of 512 employees from 4 (...) Scandinavian companies; 3 Norwegian and 1 Swedish, randomly selected from a population of 6,710 mostly Norwegian and Swedish employees in those 2 countries. The results indicate that CSR perception is a significant predictor of AC, although how employees feel that the company cares about them has stronger explanatory power on AC. Contrary to the few other studies addressing AC and CSR, gender was not found to be a significant variable in the model. (shrink)

To what extent should we use technological advances to try to make better human beings? Leading philosophers debate the possibility of enhancing human cognition, mood, personality, and physical performance, and controlling aging. Would this take us beyond the bounds of human nature? These are questions that need to be answered now.

In the Aristotelian tradition, the psychological difference between virtue and continence is commonly understood in terms of inner harmony versus inner conflict. Virtuous agents experience inner harmony between feeling and action because they do not care to do other than what their circumstances call for, whereas continent agents feel conflicted about doing what is called for because of competing concerns. Critics of this view argue, however, that when the circumstances require sacrificing something of genuine value, virtuous agents can indeed feel (...) conflicted about acting well. But if this is so, what differentiates virtuous from merely continent agency? This essay argues that the traditional distinction conflates two aspects of virtue as well as two species of continence. And distinguishing between them provides resources for making sense of the complex relationship between inner conflict and good moral agency. (shrink)

For the people who make them, music recommender systems hold a utopian promise: they can broaden listeners' horizons and help obscure musicians find audiences, taking advantage of the enormous catalogs offered by companies like Spotify, Apple Music, and their kin. But for critics, recommender systems have come to epitomize the potential harms of algorithms: they seem to reduce expressive culture to numbers, they normalize ever-broadening data collection, and they profile their users for commercial ends, tearing the social fabric into isolated (...) patches of atomized individuals. Drawing on years of ethnographic fieldwork, anthropologist Nick Seaver offers an account of how the makers of music recommendation navigate these tensions: how product managers understand their relationship with the users they want to help and to capture, how engineers imagine the abstract geography of the "world of music" as a space they control and care for, how scientists conceive of listening itself as a kind of data processing. The book rehumanizes the algorithmic systems that shape our world, foregrounding the ideas animating the people who build and maintain them. Seaver braids together the thinking of programmers and anthropologists, opening up the cultural world of computation in a vividly theorized book that ranges widely from cosmology to calculation, metaphor to myth, and captivation to care.

I argue that at least one of the following propositions is true: the human species is very likely to become extinct before reaching a ’posthuman’ stage; any posthuman civilization is extremely unlikely to run a significant number of simulations of its evolutionary history ; we are almost certainly living in a computer simulation. It follows that the belief that there is a significant chance that we shall one day become posthumans who run ancestor-simulations is false, unless we are currently living (...) in a simulation. I discuss some consequences of this result. (shrink)

_Anthropic Bias_ explores how to reason when you suspect that your evidence is biased by "observation selection effects"--that is, evidence that has been filtered by the precondition that there be some suitably positioned observer to "have" the evidence. This conundrum--sometimes alluded to as "the anthropic principle," "self-locating belief," or "indexical information"--turns out to be a surprisingly perplexing and intellectually stimulating challenge, one abounding with important implications for many areas in science and philosophy. There are the philosophical thought experiments and paradoxes: (...) the Doomsday Argument; Sleeping Beauty; the Presumptuous Philosopher; Adam & Eve; the Absent-Minded Driver; the Shooting Room. And there are the applications in contemporary science: cosmology ; evolutionary theory ; the problem of time's arrow ; quantum physics ; game-theory problems with imperfect recall ; even traffic analysis. _Anthropic Bias_ argues that the same principles are at work across all these domains. And it offers a synthesis: a mathematically explicit theory of observation selection effects that attempts to meet scientific needs while steering clear of philosophical paradox. (shrink)

Our paradigms of aesthetic value condition the philosophical questions we pose and hope to answer about it. Theories of aesthetic value are typically individualistic, in the sense that the paradigms they are designed to capture, and the questions to which they are offered as answers, center the individual’s engagement with aesthetic value. Here I offer some considerations that suggest that such individualism is a mistake and sketch a communitarian way of posing and answering questions about the nature of aesthetic value.

Views on addiction are often polarised - either addiction is a matter of choice, or addicts simply can't help themselves. But perhaps addiction falls between the two? This book contains views from philosophy, neuroscience, psychiatry, psychology, and the law exploring this middle ground between free choice and no choice.

The human brain has some capabilities that the brains of other animals lack. It is to these distinctive capabilities that our species owes its dominant position. Other animals have stronger muscles or sharper claws, but we have cleverer brains. If machine brains one day come to surpass human brains in general intelligence, then this new superintelligence could become very powerful. As the fate of the gorillas now depends more on us humans than on the gorillas themselves, so the fate of (...) our species then would come to depend on the actions of the machine superintelligence. But we have one advantage: we get to make the first move. Will it be possible to construct a seed AI or otherwise to engineer initial conditions so as to make an intelligence explosion survivable? How could one achieve a controlled detonation? To get closer to an answer to this question, we must make our way through a fascinating landscape of topics and considerations. Read the book and learn about oracles, genies, singletons; about boxing methods, tripwires, and mind crime; about humanity's cosmic endowment and differential technological development; indirect normativity, instrumental convergence, whole brain emulation and technology couplings; Malthusian economics and dystopian evolution; artificial intelligence, and biological cognitive enhancement, and collective intelligence.

This book explores both the embodied nature of social life and the social nature of human bodily life. It provides an accessible review of the contemporary social science debates on the body, and develops a coherent new perspective. Nick Crossley critically reviews the literature on mind and body, and also on the body and society. He draws on theoretical insights from the work of Gilbert Ryle, Maurice Merleau-Ponty, George Herbert Mead and Pierre Bourdieu, and shows how the work of (...) these writers overlaps in interesting and important ways which, when combined, provide the basis for a persuasive and robust account of human embodiment. The Social Body provides a timely review of the theoretical approaches to the sociology of the body. It offers new insights, and a coherent new perspective on the body. It will be valuable reading for students and academics in sociology, philosophy, anthropology, psychology, and cultural studies. (shrink)

I argue that eating meat is morally good and our duty when it is part of a practice that has benefited animals. The existence of domesticated animals depends on the practice of eating them, and the meat-eating practice benefits animals of that kind if they have good lives. The argument is not consequentialist but historical, and it does not apply to nondomesticated animals. I refine the argument and consider objections.

Practice, Spatiality and Embodied Emotions: An Outline of a Geography of Practice The paper outlines an approach to social analysis/human geography taking off from a social ontology of practice. This means a focus of attention to embodied or practical knowledges and their formation in people's everyday lives, to the world of experiences and emotions, and to the infinitude of encounters through which we make the world and are made by it in turn. The paper proceeds in three parts. First, considering (...) the way in which subjectivity and identity are created in and through practices sets the ground. The two following sections are extensions from that discussing "embodiment and spatiality" and "affectivity and emotion" respectively. The purpose is threefold; to develop the sensuous character of practice, to consider the spatialities involved in that character, and to discuss possible developments including power and the social differentiation of bodies. The paper is concluded by a short discussion of the geographies following from the suggested account. (shrink)

A theory of aesthetic value should explain what makes aesthetic value good. Current views about what makes aesthetic value good privilege the individual’s encounter with aesthetic value—listening to music, reading a novel, writing a poem, or viewing a painting. What makes aesthetic value good is its benefit to the individual appreciator. But engagement with aesthetic value is often a social, participatory matter: sharing and discussing aesthetic goods, imitating aesthetic agents, dancing, cooking, dining, or making music together. This article argues that (...) we should understand aesthetic value in a way that centers these social forms of aesthetic engagement. To this end, the article argues that there is a social practice of aesthetic valuing, characterized as a participatory practice governed by the value of aesthetic community, which engages us in the social development of our capacities for discretionary valuing and volitional openness. Current theories of aesthetic value have trouble capturing the character of the practice of aesthetic valuing, and this motivates a novel communitarian theory of aesthetic value: aesthetic value is what is worthy of engagement in the social practice of aesthetic valuing.

In this article, I argue that God is authoritative over us because he is our divine, causal parent. As our causal parent, God has duties to relate to us, but he can only fulfill those duties if he has the practical authority to give us commands aimed at our sanctification. From ought-implies-can reasoning, I conclude that God has that authority. After I make this argument, I show how the view has significant advantages over extant arguments for divine authority and can (...) help solve other significant problems in philosophy of religion.

A metric space is said to be locally non-compact if every neighborhood contains a sequence that is eventually bounded away from every element of the space, hence contains no accumulation point. We show within recursive mathematics that a nonvoid complete metric space is locally non-compact iff it is without isolated points.The result has an interesting consequence in computable analysis: If a complete metric space has a computable witness that it is without isolated points, then every neighborhood contains a computable sequence (...) that is eventually computably bounded away from every computable element of the space.

Specker sequences are constructive, increasing, bounded sequences of rationals that do not converge to any constructive real. A sequence is said to be a strong Specker sequence if it is Specker and eventually bounded away from every constructive real. Within Bishop's constructive mathematics we investigate non-decreasing, bounded sequences of rationals that eventually avoid sets that are unions of sequences of intervals with rational endpoints. This yields surprisingly straightforward proofs of certain basic results fromconstructive mathematics. Within Russian constructivism, we show how (...) to use this general method to generate Specker sequences. Furthermore, we show that any nonvoid subset of the constructive reals that has no isolated points contains a strictly increasing sequence that is eventually bounded away from every constructive real. If every neighborhood of every point in the subset contains a rational number different from that point, the subset contains a strong Specker sequence. (shrink)

It is intuitively plausible that art and imagination are intimately connected. This chapter explores attempts to explain that connection. We focus on three areas in which art and imagination might be linked: production, ontology, and appreciation. We examine views which treat imagination as a fundamental human faculty, and aim for comprehensive accounts of art and artistic practice: for example, those of Kant and Collingwood. We also discuss philosophers who argue that a specific kind of imagining may explain some particular element (...) of the artistic domain: for example, Walton's ideas about representational art, and Kivy’s about reading.

It is common to allocate scarce health care resources by maximizing QALYs per dollar. This approach has been attacked by disability-rights advocates, policy-makers, and ethicists on the grounds that it unjustly discriminates against the disabled. The main complaint is that the QALY-maximizing approach implies a seemingly unsatisfactory conclusion: other things being equal, we should direct life-saving treatment to the healthy rather than the disabled. This argument pays insufficient attention to the downsides of the potential alternatives. We show that this sort (...) of discrimination is one of four unpalatable consequences that any approach to priority setting in health care must face. We argue that, given the alternatives, it is far from clear that we should revise the QALY-maximizing approach in response to this objection. (shrink)

Articulate and perceptive, Intersubjectivity is a text that explains the notions of intersubjectivity as a central concern of philosophy, sociology, psychology, and politics. Going beyond this broad-ranging introduction and explication, author Nick Crossley provides a critical discussion of intersubjectivity as an interdisciplinary concept to shed light on our understanding of selfhood, communication, citizenship, power, and community. The volume traces the contributions of key thinkers engaged within the intersubjectivist tradition, including Husserl, Buber, Kojeve, Merlau-Ponty, Mead, Wittgenstein, Schutz, and Habermas. A (...) clear, concise introduction to a range of difficult concepts and thinkers, Intersubjectivity demystifies this very interdisciplinary subject for advanced and graduate-level students of philosophy, sociology, social psychology, and social and political theory.

A dizzying trip through the mind(s) of the provocative and influential thinker Nick Land. During the 1990s British philosopher Nick Land's unique work, variously described as “rabid nihilism,” “mad black deleuzianism,” and “cybergothic,” developed perhaps the only rigorous and culturally-engaged escape route out of the malaise of “continental philosophy” —a route that was implacably blocked by the academy. However, Land's work has continued to exert an influence, both through the British “speculative realist” philosophers who studied with him, and (...) through the many cultural producers—writers, artists, musicians, filmmakers—who have been invigorated by his uncompromising and abrasive philosophical vision. Beginning with Land's early radical rereadings of Heidegger, Nietzsche, Kant and Bataille, the volume collects together the papers, talks and articles of the mid-90s—long the subject of rumour and vague legend (including some work which has never previously appeared in print)—in which Land developed his futuristic theory-fiction of cybercapitalism gone amok; and ends with his enigmatic later writings in which Ballardian fictions, poetics, cryptography, anthropology, grammatology and the occult are smeared into unrecognisable hybrids. Fanged Noumena gives a dizzying perspective on the entire trajectory of this provocative and influential thinker's work, and has introduced his unique voice to a new generation of readers. (shrink)

Philosophers often characterize discourse in general as aiming at some sort of convergence (in beliefs, plans, dispositions, feelings, etc.), and many views about aesthetic discourse in particular affirm this thought. I argue that a convergence norm does not govern aesthetic discourse. The conversational dynamics of aesthetic discourse suggest that typical aesthetic claims have directive force. I distinguish between dynamic and illocutionary force and develop related theories of each for aesthetic discourse. I argue that the illocutionary force of aesthetic utterances is (...) typically invitational because its dynamic force is influenced by a ‘communal’ norm. I draw on dynamic pragmatics to develop a formal account of this dynamic force that explains why invitation has pride of place in aesthetic conversation. It turns out that the end of aesthetic discourse is not convergence but a distinctive form of community, a kind of harmony of individuality, that is compatible with aesthetic disagreement. If this is right, then convergence theories of aesthetic and normative discourse, and of conversation in general, need to be revised. (shrink)

Positions on the ethics of human enhancement technologies can be (crudely) characterized as ranging from transhumanism to bioconservatism. Transhumanists believe that human enhancement technologies should be made widely available, that individuals should have broad discretion over which of these technologies to apply to themselves, and that parents should normally have the right to choose enhancements for their children-to-be. Bioconservatives (whose ranks include such diverse writers as Leon Kass, Francis Fukuyama, George Annas, Wesley Smith, Jeremy Rifkin, and Bill McKibben) are generally (...) opposed to the use of technology to modify human nature. A central idea in bioconservativism is that human enhancement technologies will undermine our human dignity. To forestall a slide down the slippery slope towards an ultimately debased ‘posthuman’ state, bioconservatives often argue for broad bans on otherwise promising human enhancements. This paper distinguishes two common fears about the posthuman and argues for the importance of a concept of dignity that is inclusive enough to also apply to many possible posthuman beings. Recognizing the possibility of posthuman dignity undercuts an important objection against human enhancement and removes a distortive double standard from our field of moral vision. (shrink)

Social networking sites have challenged ethical issues about users’ information security and privacy. SNS users are concerned about their privacy and need to control the information they share and its use. This paper examines the security of SNS by taking a look at the influence of users’ perceived control of information over their information-sharing behaviors. Employing an empirical study, this paper demonstrates the importance of perceived control in SNS users’ information-sharing behaviors. Specifically, perceived control has been found to be negatively (...) related to perceived privacy risk and attitude toward information sharing, which in turn has an impact on their information-sharing behaviors. In addition, gender has been shown to be an important factor that moderates the influences of both perceived control and perceived privacy risk on SNS users’ attitudes toward information sharing. Theoretical and practical implications are discussed. (shrink)

This article responds to recent debates in critical algorithm studies about the significance of the term “algorithm.” Where some have suggested that critical scholars should align their use of the term with its common definition in professional computer science, I argue that we should instead approach algorithms as “multiples”—unstable objects that are enacted through the varied practices that people use to engage with them, including the practices of “outsider” researchers. This approach builds on the work of Laura Devendorf, Elizabeth Goodman, (...) and Annemarie Mol. Different ways of enacting algorithms foreground certain issues while occluding others: computer scientists enact algorithms as conceptual objects indifferent to implementation details, while calls for accountability enact algorithms as closed boxes to be opened. I propose that critical researchers might seek to enact algorithms ethnographically, seeing them as heterogeneous and diffuse sociotechnical systems, rather than rigidly constrained and procedural formulas. To do so, I suggest thinking of algorithms not “in” culture, as the event occasioning this essay was titled, but “as” culture: part of broad patterns of meaning and practice that can be engaged with empirically. I offer a set of practical tactics for the ethnographic enactment of algorithmic systems, which do not depend on pinning down a singular “algorithm” or achieving “access,” but which rather work from the partial and mobile position of an outsider.

The standard interpretation of cognitive reflection tests assumes that correct responses are reflective and lured responses are unreflective. However, prior process-tracing of mathematical reflection tests has cast doubt on this interpretation. In two studies (N = 201), we deployed a validated think-aloud protocol in-person and online to test how this assumption is satisfied by the new, validated, less familiar, and less mathematical verbal Cognitive Reflection Test (vCRT). Importantly, thinking aloud did not disrupt test performance compared to a control group. Moreover, (...) verbalized thoughts in both studies revealed that most (but not all) correct responses involved reflection and that most (but not all) lured responses lacked reflection. These data suggest that the vCRT usually satisfies the standard interpretation of the reflection tests (albeit not without exceptions) and that the vCRT can be a good measure of the construct theorized by the two-factor explication of ‘reflection’ (as deliberate and conscious).

In participatory activities in the workplace, employees are invited to raise problems and suggest improvements to the management. Although it is widely acknowledged that employees rarely control decisions in these settings, little is known about the interactional resources that employees and managers draw upon when negotiating consensus about which initiatives to pursue in the future. We analyse interactions from participatory meetings in an industrial setting in relation to the topic of work shoes, showing how the participants orient to both their (...) relative deontic rights and epistemic rights. The analysis suggests that besides their low deontic status, employees’ fragile epistemic status constitutes an important but overlooked challenge to achieving improved working conditions through the participatory activities.

Contemporary philosophical attitudes toward beauty are hard to reconcile with its importance in the history of philosophy. Philosophers used to allow it a starring role in their theories of autonomy, morality, or the good life. But today, if beauty is discussed at all, it is often explicitly denied any such importance. This is due, in part, to the thought that beauty is the object of “disinterested pleasure”. In this paper I clarify the notion of disinterest and develop two general strategies (...) for resisting the emphasis on it, in the hopes of getting a clearer view of beauty’s significance. I present and discuss several literary depictions of the encounter with beauty that motivate both strategies. These depictions illustrate the ways in which aesthetic experience can be personally transformative. I argue that they present difficulties for disinterest theories and suggest we abandon the concept of disinterest to focus instead on the special kind of interest beauty fuels. I propose a closer look at the Platonic thought that beauty is the object of love. (shrink)

The terms "imagination'' and "imaginative'' can be readily applied to a profusion of attitudes, experiences, activities, and further phenomena. The heterogeneity of the things to which they're applied prompts the thoughts that the terms are polysemous, and that there is no single, coherent, fruitful conception of imagination to be had. Nonetheless, much recent work on imagination ascribes implicitly to a univocal way of thinking about imaginative phenomena: the imitation theory, according to which imaginative experiences imitate other experiences. This approach is (...) infelicitous. It issues in unhelpful descriptions of imaginative activities, experiences, and attitudes, and frustrates theorizing about imagination's applications and intensional characteristics. A better way of thinking about imagination is the lens theory, according to which the imagination is a set of ways to focus, refine, clarify or concentrate the matter of other experiences. This approach offers better characterizations of imaginative phenomena, and promises brighter theoretical illumination of them. (shrink)

Despite thermodynamic, bioenergetic and phylogenetic failings, the 81‐year‐old concept of primordial soup remains central to mainstream thinking on the origin of life. But soup is homogeneous in pH and redox potential, and so has no capacity for energy coupling by chemiosmosis. Thermodynamic constraints make chemiosmosis strictly necessary for carbon and energy metabolism in all free‐living chemotrophs, and presumably the first free‐living cells too. Proton gradients form naturally at alkaline hydrothermal vents and are viewed as central to the origin of life. (...) Here we consider how the earliest cells might have harnessed a geochemically created proton‐motive force and then learned to make their own, a transition that was necessary for their escape from the vents. Synthesis of ATP by chemiosmosis today involves generation of an ion gradient by means of vectorial electron transfer from a donor to an acceptor. We argue that the first donor was hydrogen and the first acceptor CO2. (shrink)

Remarkable progress in the mathematics and computer science of probability has led to a revolution in the scope of probabilistic models. In particular, ‘sophisticated’ probabilistic methods apply to structured relational systems such as graphs and grammars, of immediate relevance to the cognitive sciences.

Here, we introduce the historical and conceptual foundations of the approach, explore (...) how the approach relates to studies of explicit probabilistic reasoning, and give a brief overview of the field as it stands today.

Cognitive scientists have revealed systematic errors in human reasoning. There is disagreement about what these errors indicate about human rationality, but one upshot seems clear: human reasoning does not seem to fit traditional views of human rationality. This concern about rationality has made its way through various fields and has recently caught the attention of philosophers. The concern is that if philosophers are prone to systematic errors in reasoning, then the integrity of philosophy would be threatened. In this paper, I (...) present some of the more famous work in cognitive science that has marshaled this concern. Then I present reasons to think that those with training in philosophy will be less prone to certain systematic errors in reasoning. The suggestion is that if philosophers could be shown to be less prone to such errors, then the worries about the integrity of philosophy could be constrained. Then I present evidence that, according to performance on the CRT (Frederick 2005), those who have benefited from training and selection in philosophy are indeed less prone to one kind of systematic error: irrationally arbitrating between intuitive and reflective responses. Nonetheless, philosophers are not entirely immune to this systematic error, and their proclivity for this error is statistically related to their responses to a variety of philosophical questions. So, while the evidence herein puts constraints on the worries about the integrity of philosophy, it by no means eliminates these worries. The conclusion, then, is that the present evidence offers prima facie reasons to ascribe a mitigated privilege to philosophers' ability to rationally arbitrate between intuitive and reflective responses.

Apologies can be profoundly meaningful, yet many gestures of contrition - especially those in legal contexts - appear hollow and even deceptive. Discussing numerous examples from ancient and recent history, I Was Wrong argues that we suffer from considerable confusion about the moral meanings and social functions of these complex interactions. Rather than asking whether a speech act 'is or is not' an apology, Smith offers a highly nuanced theory of apologetic meaning. Smith leads us though a series of rich (...) philosophical and interdisciplinary questions, explaining how apologies have evolved from a confluence of diverse cultural and religious practices that do not translate easily into secular discourse or gender stereotypes. After classifying several varieties of apologies between individuals, Smith turns to apologies from collectives. Although apologies from corporations, governments, and other groups can be quite meaningful in certain respects, we should be suspicious of those that supplant apologies from individual wrongdoers.

We introduce new algebraic and topological semantics for inquisitive logic. The algebraic semantics is based on special Heyting algebras, which we call inquisitive algebras, with propositional valuations ranging over only the ¬¬-fixpoints of the algebra. We show how inquisitive algebras arise from Boolean algebras: for a given Boolean algebra B, we define its inquisitive extension H(B) and prove that H(B) is the unique inquisitive algebra having B as its algebra of ¬¬-fixpoints. We also show that inquisitive algebras determine Medvedev’s logic (...) of finite problems. In addition to the algebraic characterization of H(B), we give a topological characterization of H(B) in terms of the recently introduced choice-free duality for Boolean algebras using so-called upper Vietoris spaces (UV-spaces). In particular, while a Boolean algebra B is realized as the Boolean algebra of compact regular open elements of a UV-space dual to B, we show that H(B) is realized as the algebra of compact open elements of this space. This connection yields a new topological semantics for inquisitive logic. (shrink)

With the increasing popularity of social media, a new ethics debate has arisen over marketing and technology in the current digital era. People are using online communities but they have concern about information credibility through word of mouth in these platforms. Social media is becoming increasingly influential in shaping individuals’ decision-making as more and better quality information about products is made available. In this research, a social word-of-mouth model proposes using a survey to test the model in a popular travel (...) community. The model highlights the role of social media and social support in social networking sites, identifying increasing credibility and information usefulness resulting in an ethical environment to adopt word of mouth. The theoretical and practical implications of the study are both detailed. (shrink)

Analytic moral philosophers have generally failed to engage in any substantial way with the cultural history of morality. This is a shame, because a genealogy of morals can help us accomplish two important tasks. First, a genealogy can form the basis of an epistemological project, one that seeks to establish the epistemic status of our beliefs or values. Second, a genealogy can provide us with functional understanding, since a history of our beliefs, values or institutions can reveal some inherent dynamic (...) or pattern which may be problematically obscured from our view. In this paper, I try to make good on these claims by offering a sketchy genealogy of emancipatory values, or values which call for the liberation of persons from systems of dominance and oppression. The real history of these values, I argue, is both epistemologically vindicatory and functionally enlightening. (shrink)
