How do clinical psychiatrists arrive at their diagnostic conclusions? Little attention has been directed to this question by philosophers of psychiatry. Adrian Kind presents a systematic, in-depth philosophical investigation into this question and argues that psychiatric diagnostic reasoning can be understood as a model-based reasoning procedure analogous to scientific model-based reasoning. To support this, he draws on ideas from the philosophy of science, psychiatry, cognitive science, and artificial intelligence. This study is an invaluable resource for practicing psychiatrists, philosophers interested (...) in psychiatry, and researchers in artificial intelligence or cognitive science interested in medical cognition.

The purpose of this discussion is twofold. First, I want to shed some light on Kant's concept of personhood as rational agency, by situating it in the context of the first Critique's conception of the self as defined by its rational dispositions. I hope to suggest that this concept of personhood cannot be simply grafted onto an essentially Humean conception of the self that is inherently inimical to it, as I believe Rawls, Gewirth, and others have tried to do. Instead (...) I will try to show how deeply embedded this concept of personhood is in Kant's conception of the self as rationally unified consciousness. Second, I want to deploy this embedded concept of personhood as the basis for an analysis of the phenomenon of xenophobia. (shrink)

John McDowell espouses a certain conception of the thinking subject: as an embodied, living, finite being, with a capacity for experience that can take in the world, and stand in relations of warrant to subjects' beliefs. McDowell presents this conception of the subject as requiring a related conception of the world: as not located outside the conceptual sphere. In this latter conception, idealism and common-sense realism are supposed to coincide. But I suggest that McDowell's conception of the subject scuppers this (...) intended coincidence. The upshot is a dilemma: McDowell can retain his conception of the subject, but lose the coincidence; or he can keep the coincidence, but abandon his conception of the subject. (shrink)

Biologists often study living systems in light of their having evolved, of their being the products of various processes of heredity, adaptation, ancestry, and so on. In their investigations, then, biologists think comparatively: they situate lineages into models of those evolutionary processes, comparing their targets with ancestral relatives and with analogous evolutionary outcomes. This element characterizes this mode of investigation - 'comparative thinking' - and puts it to work in understanding why biological science takes the shape it does. Importantly, comparative (...) thinking is local: what we can do with knowledge of a lineage is limited by the evolutionary processes into which it fits. In light of this analysis, the Element examines the experimental study of animal cognition, and macroevolutionary investigation of the 'shape of life', demonstrating the importance of comparative thinking in understanding both the power and limitations of biological knowledge.

Immanuel Kant is one of Alain Badiou’s principle philosophical enemies. Kant’s critical philosophy is anathema to Badiou not only because of the latter’s openly aired hatred of the motif of finitude so omnipresent in post-Kantian European intellectual traditions—Badiou blames Kant for inventing this motif—but also because of its idealism. For Badiou-the-materialist, as for any serious philosophical materialist writing in Kant’s wake, transcendental idealism must be dismantled and overcome. In his most recent works, Badiou attempts to invent a non-Kantian notion of (...) the transcendental, a notion compatible with the basic tenets of materialism. However, from 1988’s Being and Event up through the present, Badiou’s oeuvre contains indications that he hasn’t managed fully to purge the traces of Kantian transcendental idealism that arguably continue to haunt his system—with these traces clustering around a concept Badiou christens “counting-for-one”. The result is that, in the end, Kant’s shadow still falls over Badiouian philosophy—this is despite Badiou’s admirable, sophisticated, and instructive attempts to step out from under it—thus calling into question this philosophy’s self-proclaimed status as materialist through and through.

This is a constructive critique of Habermas’s account of rationality, which is central to his political theory and has sparked theoretical and empirical research across academia. Habermas and many critical theorists caricature means-ends rationality (the ability to pick good means to ends), e.g. by wrongly depicting it as egocentric. This weakens Habermas’s attempt to distinguish means-ends rationality from his hugely important and influential idea of communicative rationality (roughly, the rationality of genuine discussion). I suggest that sincerity and autonomy, rather than (...) non-egocentrism, are the key distinguishing features of communicative rationality. This shows that communicative rationality actually overlaps with means-ends rationality. Indeed, means-ends rationality is needed by critical theorists, as I exemplify by showing its use in deliberative democracy. Moreover, means-ends rationality will be present in discourse ethics, as I show with the example of moral discourse about gay marriage. My article thus challenges decades of what Habermas and critical theorists have written on means-ends and communicative rationality, but I stay broadly true to – and hopefully improve – Habermas’s account of rationality.

An argument that we should be optimistic about the capacity of “methodologically omnivorous” geologists, paleontologists, and archaeologists to uncover truths about the deep past. -/- The “historical sciences”—geology, paleontology, and archaeology—have made extraordinary progress in advancing our understanding of the deep past. How has this been possible, given that the evidence they have to work with offers mere traces of the past? In Rock, Bone, and Ruin, Adrian Currie explains that these scientists are “methodological omnivores,” with a variety of (...) strategies and techniques at their disposal, and that this gives us every reason to be optimistic about their capacity to uncover truths about prehistory. Creative and opportunistic paleontologists, for example, discovered and described a new species of prehistoric duck-billed platypus from a single fossilized tooth. Examining the complex reasoning processes of historical science, Currie also considers philosophical and scientific reflection on the relationship between past and present, the nature of evidence, contingency, and scientific progress. -/- Currie draws on varied examples from across the historical sciences, from Mayan ritual sacrifice to giant Mesozoic fleas to Mars's mysterious watery past, to develop an account of the nature of, and resources available to, historical science. He presents two major case studies: the emerging explanation of sauropod size, and the “snowball earth” hypothesis that accounts for signs of glaciation in Neoproterozoic tropics. He develops the Ripple Model of Evidence to analyze “unlucky circumstances” in scientific investigation; examines and refutes arguments for pessimism about the capacity of the historical sciences, defending the role of analogy and arguing that simulations have an experiment-like function. Currie argues for a creative, open-ended approach, “empirically grounded” speculation. (shrink)

O privire fugitivă asupra unora dintre religiile lumii antice scoate la iveală faptul că, indiferent de structura sa și de teritoriul în care s-a răspândit, credința într-o viață fără boli și suferințe a fost idealul permanent al omului. Astfel că, alături de nădejdea în viața de apoi, încrederea într-un trai mai bun încă de pe pământ a reprezentat o constată a vieții private și publice. În acest sens, au existat divinități, dar și specialiști, care s-au îngrijit de întreținerea speranțelor oamenilor. (...) „Într-adevăr, cultura indo-europeană cunoștea un singur tip de intelectual, cel care se îngrijea de toate activitățile legate de cuvânt: era preot (cunoscând rugăciunile și formulele rituale), era istoric (știind să povestească tradițiile și istoria străveche a tribului său), era jurist (cunoscând pe de rost formulele dreptului cutumiar), era poet (stăpânind tehnica dificilă a compunerii), era povestitor (știind să recite pentru delectarea auditoriului o cantitate însemnată de texte și tradiții orale), era medic (cunoscând formulele magice vindecătoare)”.24 Cu toată această diversificare, oamenii au așteptat în continuare venirea unui Mântuitor dintr-o altă lume, Care să le vindece bolile, să le ierte păcatele și să le aducă învierea din morți. Acest lucru s-a întâmplat prin Întruparea Fiului lui Dumnezeu „la plinirea vremii” (Galateni 4, 4-5). (shrink)

Many-minds arguments are flooding into legal theory. Such arguments claim that in some way or another, many heads are better than one; the genus includes many species, such as arguments about how legal and political institutions aggregate information, evolutionary analyses of those institutions, claims about the benefits of tradition as a source of law, and analyses of the virtues and vices of deliberation. This essay offers grounds for skepticism about many-minds arguments. I provide an intellectual zoology of such arguments and (...) suggest that they are of low utility for legal theory. Four general and recurring problems with many-minds arguments are as follows: (1) Whose minds?: The group or population whose minds are at issue is often equivocal or ill-defined. (2) Many minds, worse minds: The quality of minds is not independent of their number; rather, number endogenously influences quality, often for the worse. More minds can be systematically worse than fewer because of selection effects, incentives for epistemic free-riding, and emotional and social influences. (3) Epistemic bottlenecks: In the legal system, the epistemic benefits of many minds are often diluted or eliminated because the structure of institutions funnels decisions through an individual decisionmaker, or a small group of decisionmakers, who occupy a kind of epistemic bottleneck or chokepoint. (4) Many minds vs. many minds: The insight that many heads can be better than one gets little purchase on the institutional comparisons that pervade legal theory, which are typically many-to-many comparisons rather than one-to-many.

The rural/metropolitan/wilderness hybrid central to urban shrinkage directly challenges a commonly held belief that a city consists of a dense concentration of people living in a limited geographical area, one where the primary means of production is non-agricultural. In addition, the urban condition of shrinkage tests the dominant current of growth management that has guided urban design, development, and land use. In this essay we will explore how this hybrid presents an alternative to the production and realization of surplus value (...) that predominates throughout the contemporary landscape of neoliberal planetary urbanization. It will be argued that this process of urbanization is premised upon modalities of urban commoning, or practices that bring a variety of social and environmental struggles into relationship with each other, dismantling the apparatuses of capture that bring land-use and the collective energies animating available land under the control of capital.

From a number of quarters have come attempts to answer some form of skepticism—about knowledge of the external world, freedom of the will, or moral reasons—by showing it to be performatively self-defeating. Examples of this strategy are subject to a number of criticisms, in particular the criticism that they fail to shift the burden of proof from the anti-skeptical position, and so fail to establish the epistemic entitlement they seek. To these approaches I contrast one way of understanding Kant’s core (...) anti-skeptical arguments in the Critique of Pure Reason. Kant’s goal is the more modest one of showing the applicability of the concepts of substance and cause to experience, against those who might call such application incoherent, or a category mistake. I explain why this goal makes Kant’s approach more promising than those of neo-Kantian practitioners of otherwise structurally-similar strategies. (shrink)

This article seeks to answer the following questions: is Quentin Skinner right to claim that actions in the past should not be described by means of concepts not available at the time those actions occurred? And is Ian Hacking right to claim that such descriptions do not merely describe but actually change the past? The author begins by arguing that it is not clear precisely what Skinner is claiming and shows how, under the pressure of criticism, his methodological strictures collapse (...) into trivialities. The author then argues that, although Hacking has given us no reason to accept his claim, we can make sense of it by appealing to the idea of a "Cambridge change." The author concludes by suggesting that as long as we are exercising the right kind of concepts, a suitably modified version of Hacking 's conclusion can be retained. Key Words: action • history • changes in the past • Quentin Skinner • Ian Hacking. (shrink)

The issue of time-awareness presents a critical challenge for empiricism: if temporal properties are not directly perceived, how do we become aware of them? A unique empiricist account of time-awareness suggested by Hume's comments on time in the Treatise avoids the problems characteristic of other empiricist accounts. Hume's theory, however, has some counter-intuitive consequences. The failure of empiricists to come up with a defensible theory of time-awareness lends prima facie support to a non-empiricist theory of ideas.

My intellectual journey in philosophy proceeded along two mountainous paths that coincided at their base, but forked less than halfway up the incline. The first is that of my philosophical development, a steep but steady and continuous ascent. It began in my family, and accelerated in high school, art school, college, and graduate school. Those foundations propelled my philosophical research into the nature of rationality and its relation to the structure of the self, a long-term project focused on the Kantian (...) and Humean metaethical traditions in Anglo-American analytic philosophy. It would have been impossible to bring this project to completion without the anchor, compass, and conceptual mapping provided by my prior, longstanding involvement in the practice and theory of Vedic philosophy. The second path is that of my professional route through the field of academic philosophy, which branched onto a rocky detour in graduate school, followed by a short but steep ascent, followed next by a much steeper, sustained descent off that road, into the ravine, down in flames, and out of the profession. In order to reach the summit of the first path, I had to reach the nadir of the second. It was the right decision. My yoga practice cushioned my landing. (shrink)

In 1951 John Rawls expressed these convictions about the fundamental issues in metaethics: [T]he objectivity or the subjectivity of moral knowledge turns, not on the question whether ideal value entities exist or whether moral judgments are caused by emotions or whether there is a variety of moral codes the world over, but simply on the question: does there exist a reasonable method for validating and invalidating given or proposed moral rules and those decisions made on the basis of them? For (...) to say of scientific knowledge that it is objective is to say that the propositions expressed therein may be evidenced to be true by a reasonable and reliable method, that is, by the rules and procedures of what we may call "inductive logic"; and, similarly, to establish the objectivity of moral rules, and the decisions based upon them, we must exhibit the decision procedure, which can be shown to be both reasonable and reliable, at least in some cases, for deciding between moral rules and lines of conduct consequent to them.1 In this passage Rawls reconfigured the issue of moral objectivity and so reoriented the practice of metaethics from linguistic analysis to rational methodology. In so doing, his work has provided inspiration to philosophers as disparate in normative views as Thomas Nagel,2 Richard Brandt3, Alan Gewirth4, and David Gauthier.5 Rawls replaced the Moorean question, Do moral terms refer? with the Rawlsian question, Can moral judgments be the outcome of a rational and reliable procedure? He later gave a resoundingly positive answer to this question6 and later still, a more tentative one.7 Rawls' considered qualification of his earlier enthusiasm about the extent to which moral philosophy could be "part of the theory of rational choice"8 is a tribute to the seriousness with which he took his critics' objections.

In the preface to the second edition of his Critique of Pure Reason, Kant laments thatit still remains a scandal to philosophy and to human reason in general that the existence of things outside us … must be accepted on faith, and if anyone thinks good to doubt their existence, we are unable to counter his doubts by any satisfactory proof. The two editions of the Critique each contain a celebrated refutation of epistemological scepticisms like those of Descartes and Hume. (...) The first edition refutation has been widely decried as relying on an objectionable sort of idealism. The refutation of the second edition, though rather more difficult to interpret than the first, has usually been read as a mere reworking of the first. (shrink)

How could social scientists and cultural theorists take responsibility in engaging with science? How might they develop an experimental sensibility to the links between the production of knowledge and the production of existence or forms of life? Critically outlining key fields in the social and cultural studies of science, we interrogate a number of approaches to these questions. The first approach tries to make sense of how science operates in relation to economic, political and cultural forces. The second analyses science (...) as a form of embodied work or practice. The third engages with science as collaborative-collective elaboration of events, ranging across cultural theory, contemporary art and participant ethnographies. This outline sketches a vector of responsibility across this diverse range of engagements, suggesting that contemporary movements between science and other knowledges constitute ethical and political imperatives.

What does it mean to have an Anthropocene body? The Anthropocene period is putatively defined by flows of hydrocarbons and hydrocarbon derivatives (fuels, plastics, fertilizers, etc.), and the very term ‘Anthropocene’ suggests an increasing awareness of the finitude and contingency of contemporary corporealities. This article explores the idea of modelling an Anthropocene body as a living/non-living metabolic process. While identifying bodies with molecules raises a host of problems, metabolism and hydrocarbon biomolecules display a gamut of forms of possession and ways (...) of having a body. Conversion between living and non-living forms of possession can be traced in contemporary genomic science and particularly in synthetic biology as they engineer microbes to produce next-generation biofuels. In contrast to fossil fuels, these fuels derive from genomically re-engineered microbes that digest biomass or photosynthesize to produce hydrocarbons. The problematic contemporary production of these fuels might help us to articulate what it means to have a body as a metabolic manifold of living and non-living forms of possession. (shrink)

Seit kurzem wird des öfteren in Deutschland die Ansicht geäußert, Deutschland solle nun seine fremdenfeindliche Vergangenheit im Zweiten Weltkrieg endlich hinter sich lassen und von nun ab als >>normalisiertes<< Land der Zukunft gegenübertreten. Diese Meinung entsteht aus der Voraussetzung, daß Deutschland durch seine Geschichte von Xenophobie und Genozid im Zweiten Weltkrieg als abnormal, als ungewöhnlich gekennzeichnet ist. Aber das ist nicht wahr. Deutschlands blutige Geschichte ist mit derjenigen der Vereinigten Staaten, Großbritanniens, der Niederlande, Rußlands, Chinas, Japans, der Türkei, Vietnams, Kambodschas, (...) Somalias, Ruandas, des Irak, des Kosovo, Bosniens, und anderer Länder vergleichbar. Zu vergleichen bedeutet weder zu relativieren, noch zu entschuldigen, sondern bloß anzuerkennen, daß die Verbrechen gegen die Menschlichkeit, die in verschiedenen Ländern stattfinden, einige gemeinsame Eigenschaften haben.

paper, abstract, revised handout, original handoutto appear in the Proceedings of Sinn und Bedeutung 12 (Oslo, 2007). The paper argues that the variability of the uniqueness effects exhibited by Hindi and Romanian correlatives is due to their mixed referential and quantificational nature. The account involves an articulated notion of quantification, independently motivated by donkey anaphora and quantificational subordination and consisting of both (discourse) referential components and non-referential components (dynamic operators over plural info states). The variable uniqueness effects emerge out of (...) the interaction between: (i) the semantics of wh-indefinites, singular anaphors and habitual morphology and (ii) the pragmatics of quantification, which allows for the selection of different levels of ‘zoom-in’ on the quantified-over objects.

The target article overestimates the power of money as a motive/incentive in order to justify trying to provide a biological theory. A great deal of the article is spent trying to force-fit other explanations into this course categorization. Lea & Webley's (L&W's) account seems to ignore systematic, individual differences, as well as the literature on many negative affective associations of money and behavioural economics, which is a cognitive account of money motivation.

Arthur C. Danto’s Analytical Philosophy of History has a Kantian ambition: to state the conditions that make historical knowledge possible and to show “the unhappy destiny” that attends attempts to extend modes of representation beyond these conditions. Even though Danto’s book fails to achieve this ambition, it succeeds in making a number of important—if neglected—suggestions in the course of its attempt. One concerns the significance of the progressive tense for our thinking about human agency. Another concerns the way agency can (...) impact negatively on the possibility of foreknowledge. (shrink)

Dreaming in sleep must depend on the activity of the brain as does cognition and memory in wakefulness. Yet our understanding of the physiological subtleties of state differences may still be too primitive to guide theories adequately in these areas. One can state nonetheless unequivocally that the brain in REM is poorly equipped to practice for eventualities of wakefulness through dreaming, or for consolidating into memory the complex experiences of that state. [Hobson et al., Nielsen, Solms, Vertes & Eastman, Revonsuo].

I tend to think of myself as bodily. Probably, so do you. Philosophically this takes some explaining. A candidate explanation is this: The bodily self is a physical agent. Knowledge of oneself as bodily is fundamentally knowledge of oneself as agentive; such knowledge is grounded in both experience of oneself as instantiating a bodily structure that affords a limited range of actions; and experience of oneself as a physical agent that tries to perform a limited range of actions over time. (...) By contrast René Descartes famously argued that all self-knowledge is grounded in, and cannot extend beyond, knowledge of oneself as a mental entity. If correct this would preclude the possibility of any knowledge of a bodily self, for such a thing would ex hypothesi not exist. Accordingly, this dissertation serves a dual purpose: to demonstrate why a Cartesian theory of self-knowledge is no threat to an account of bodily self knowledge; and to provide such an account. This dual purpose is achieved over the course of three chapters. The first chapter will set up the remaining two, by introducing the notion of self-identifying judgements, providing an argument in favour of bodily self knowledge on its basis, and noting two failures of this argument in light of a Cartesian response. The second and third chapter are respective attempts to address these two failures. The second chapter is explicitly concerned with the Cartesian, but is overall devoted to giving an account of the relationship between bodily experience and action. The third chapter is more programmatic, comprising a consistent set of suggestions concerning the sense of agency and its role in an account of bodily self knowledge. (shrink)

Lea & Webley (L&W) provide two alternative biological accounts of human monetary motivations, the Tool Theory and the Drug Theory. They argue that both are required for an adequate explanation. I explore the applicability of these models to philosophical discussions of how we might justify such motivations. I argue their approach is not entirely satisfactory for normative questions, since it precludes the possibility of rational non-instrumental attitudes towards money. (Published Online April 5 2006).

The recent publications reported in 2022 reveal the possibility of obtaining mouse embryos without the need for egg or sperm. These ‘artificial embryos’ can recapitulate some stages of development ex utero – from neurulation to organogenesis – without implantation. Synthetic mouse embryos might serve as a valuable model to gain further insights into early developmental stages. Indeed, it is expected for these models to be replicated by employing human cells. This promising research raises ethical issues and expands the horizon of (...) ethics in regard to the development of the human embryo. From this point of view, we state some of the new open venues for bioethical research. (shrink)

Celem niniejszej pracy jest zastosowanie wizji „Lewiatana” Thomasa Hobbesa do koncepcji superinteligencji lub nadludzkiej inteligencji, które dyskutowane jest wśród transhumanistów i poruszone jest przez takich filozofów i futurologów jak między innymi Nick Bostrom, Stanisław Lem, albo Ray Kurzweil. Inspiracją mojej pracy były pytania w rodzaju: „kiedy człowiek przestaje być autonomicznym podmiotem?” albo „czy człowiek w ogóle może być samodzielny?”. Niemniej jednak wydaje mi się, że takie pytania mogą się pojawić wtedy, kiedy człowieka rozpoznamy jako zwierzę polityczne (politikon zoon w sensie (...) Arystotelesowskim). Albowiem trudno wyobrażać sobie wyłonienie pojęcia polityki wobec człowieka samotnego, to znaczy w izolacji od innych ludzi i bez odniesienia się lub ustosunkowania się do nich. Będę argumentował z perspektywy historyka ewolucyjnego. Za badaczy posiadających wkład do takiego stanowiska można uznać Karola Darwina, Samuela Butlera, George’a Dysona i szczególnie Yuvala Noaha Harariego. Opieram się głównie na pracach dwóch ostatnich.

Beginning with the second decade of the last century, after a fierce critique of W. Dilthey and the Historical School’s epistemological approach, philosophical hermeneutics has assumed the position of “official” philosophy of history of our times. However, in our previous work we have shown that philosophical hermeneutics is not actually able to give a better answer to “What is history?” than that already offered by the Historical School. Now we would like to show that its answer to the other fundamental (...) question of the philosophy of history - “How is history to be known?” - is even more problematic, making historical science impossible. For if the being of history really is tradition as philosophical hermeneutics argues, and if the essence of tradition is language then, on the one hand, the very stability of historical meaning presupposed by any epistemological process will always be displaced by the play of what Derrida calls “différance,” the ceaseless differentiation of the signifiers and signifieds. And, on the other hand, even if historical meaning were stable enough so as to be known, it could not be grasped because, we will try to argue, the process of understanding as philosophical hermeneutics describes it is always permeated by misunderstanding.

The distinction between equality and sufficiency, much discussed in the distributive justice literature, is here applied to democratic theory. Overlooking this distinction can have significant normative implications, undermining some defences and criticisms of political equality, as I show by discussing the work of three prominent democratic theorists: Thomas Christiano, David Estlund, and Mark Warren. Most importantly, Christiano sometimes defends egalitarian conclusions using sufficientarian premises, or worries about inequality in situations where insufficiency is also part of the problem; inequality above the (...) level of sufficiency is not always as troubling. Estlund makes the reverse error. He attacks rather than defends political egalitarianism, but insufficiency seems to explain some of his concerns. Nonetheless, I show that political egalitarians may need to specify a sufficientarian threshold, to avoid levelling-down objections. Democratic theorists should thus take seriously the distinction between political equality and political sufficiency. More generally, political theorists and philosophers should be aware of omitted variable bias and interaction effects due to conceptual stretching arising from under-theorised distinctions in their thought experiments.

William Ames (1576-1633) a incarné une autorité fondamentale pour les puritains qui ont émigré en Nouvelle-Angleterre. Dans son œuvre, il a la singularité d’allier ses convictions religieuses à une mentalité ramiste. Ames considère la méthode de Ramus comme une manière adéquate de comprendre l’acquisition et la transmission des savoirs. Le système ramiste s’applique aussi au domaine de la théologie et à certaines questions liées au gouvernement de l’individu. Cet article vise à mettre en lumière cette combinaison entre le puritanisme et (...) le ramisme qui caractériserait une façon bien particulière de concevoir le gouvernement de l’individu : un modèle qui renforce la volonté de l’individu et sa capacité de contrôle, en tant qu’instruments essentiels de gouvernement, et qui renferme un objectif émancipateur et égalitaire.

The Darwinian argument in metaethics can have its memetic counterparts based on the assumption that our moral beliefs were formed in the process of cultural evolution by means of memetic natural selection. Is there any difference with respect to the debunking force of these two kinds of genealogical critiques? In this paper, I argue that there might be such difference. Therefore, it is not true that any possible naturalistically respectable causal mechanism is equally undermining for our moral beliefs. Yet, there (...) is a more profound question to be asked: should we leave the rationality of our deepest moral beliefs at the mercy of the results of empirical investigations into their causal origin? This paper argues that we should not. However, if this approach is to be justified, the autonomy of moral beliefs must be defended in a principal manner. Only then may a different account of knowledge as well as different standards of objective propositional rationality be legitimately adopted for moral beliefs — i.e. different from those proper to non-normative beliefs. It turns out that only expressivists are in a position to claim that the property in virtue of which moral beliefs perform their distinctive practical function confers autonomy on moral discourse.
