In a recent no-go theorem [Bong et al., Nature Physics (2020)], we proved that the predictions of unitary quantum mechanics for an extended Wigner’s friend scenario are incompatible with any theory satisfying three metaphysical assumptions, the conjunction of which we call “Local Friendliness”: Absoluteness of Observed Events, Locality and No-Superdeterminism. In this paper (based on an invited talk for the QBism jubilee at the 2019 Växjö conference) I discuss the implications of this theorem for QBism, as seen from the point (...) of view of experimental metaphysics. I argue that the key distinction between QBism and realist interpretations of quantum mechanics is best understood in terms of their adherence to different theories of truth: the pragmatist versus the correspondence theories. I argue that a productive pathway to resolve the measurement problem within a pragmatist view involves taking seriously the perspective of quantum betting agents, even those in what I call a “Wigner bubble”. The notion of reality afforded by QBism, I propose, will correspond to the invariant elements of any theory that has pragmatic value to all rational agents—that is, the elements that are invariant upon changes of agent perspectives. The classical notion of ‘event’ is not among those invariants, even when those events are observed by some agent. Neither are quantum states. Nevertheless, I argue that far from solipsism, a personalist view of quantum states is an expression of its precise opposite: Copernicanism. (shrink)

Adam Smith was a famous economist and moral philosopher. This book treats Smith also as a systematic philosopher with a distinct epistemology, an original theory of the passions, and a surprising philosophy mind. The book argues that there is a close, moral connection between Smith's systematic thought and his policy recommendations.

Planteamos el problema del aparecer de la hylè husserliana, lo que nos conduce al problema de la auto-donación de la vida como condición de una fenomenología de la percepción. Para solucionar este problema, establecemos las condiciones de un diálogo entre Michel Henry, que pone énfasis sobre la auto-afección de la vida inmanente, y Merleau-Ponty, que privilegia una concepción intencional del cuerpo mundano. Tal diálogo nos permite identificar un prejuicio común, cuya superación podría ofrecer la posibilidad de una solución al problema (...) del aparecer sensible desde la vida. (shrink)

Résumé Cet article se propose de proposer les conditions d’une confrontation entre la phénoménologie de la donation de Jean-Luc Marion et l’ontologie de la vie de Renaud Barbaras. Cela suppose d’établir un certain plan de convergence à propos du projet d’une description de l’apparaître pur, de la méthode et de la conception “événementiale” du phénomène et du sujet afin de faire valoir une divergence quant à la question de la naissance transcendantale du sujet.This paper aims at giving the conditions of (...) a confrontation between the phenomenology of the givenness of Jean-Luc Marion and the ontology of life of Renaud Barbaras. The project of the description of the appearing as such, the method, the “evential” conception of the phenomenon and the subject may constitute a plane of convergence previous to putting emphasis on a divergence between them about the question of the transcendental birth of the subject.

In recent years, the notion of a reason has come to occupy a central place in both metaethics and normative theory more broadly. Indeed, many philosophers have come to view reasons as providing the basis of normativity itself . The common conception is that reasons are facts that count in favor of some act or attitude. More recently, philosophers have begun to appreciate a distinction between objective and subjective reasons, where (roughly) objective reasons are determined by the facts, while subjective (...) reasons are determined by one's beliefs. My goal in this paper is to offer a plausible theory of subjective reasons. Although much attention has been focused on theories of objective reasons, very little has been offered in the literature regarding what sort of account of subjective reasons we should adopt; and what has been offered is rather perfunctory, and requires filling-out. Taking what has been said thus far as a starting point, I will consider several putative theories of subjective reasons, offering objections and amendments along the way, will settle on what I take to be a highly plausible account, and will defend that account against objections.

: Some argue that human groups have a stake in the outcome of population-genomics research and that the decision to participate in such research should therefore be subject to group permission. It is not possible, however, to obtain prior group permission, because the actual human groups under study, human demes, are unidentifiable before research begins. Moreover, they lack moral standing. If identifiable social groups with moral standing are used as proxies for demes, group approval could be sought, but at the (...) expense of unfairly exposing these surrogates to risks from which prior group approval is powerless to protect them. Unless population genomics can proceed without targeting socially defined groups, or can find other ways of protecting them, it may fall to individuals to protect the interests of the groups they care about, and to scientists to warn their subjects of the need to do so.

African Americans, compared to Whites, are starkly underrepresented in scientific and technological professions, are especially reluctant to participate as research subjects, and they express attitudes that are skeptical of science and scientific institutions. This article seeks to explain the racial gap in confidence in science (race being socially defined), putting to empirical test explanations suggested by research on human capital, inequality in educational opportunity, and culture. The results show that differential returns to schooling account for about a third of the (...) racial divide, with various cultural mechanisms explaining most of the balance. (shrink)

This is the second paper in a two-part series introducing logics for reasoning about the dynamics of knowledge and beliefs. Part I introduced different logical systems that can be used to reason about the knowledge and beliefs of a group of agents. In this second paper, I show how to adapt these logical systems to reason about the knowledge and beliefs of a group of agents during the course of a social interaction or rational inquiry. Inference, communication and observation are (...) typical examples of informative events, which have been subjected to a logical analysis. The main goal of this article is to introduce the key conceptual and technical issues that drive much of the research in this area. (shrink)

Trois objections au moins peuvent remettre en question la vocation de l’homme à la liberté. En premier lieu, l’indépendance à l’égard des déterminations extérieures, que suppose la liberté, ne semble-t-elle pas conduire à l’indifférence et à l’incapacité de choisir? En outre à supposer même que l’autodétermination soit possible dans la ressaisie pure de soi, comment, en second lieu, comprendre l’effectivité de ma résolution? Son inscription dans l’extériorité risque en effet d’en condamner la pureté. Enfin, la pensée de la liberté ne (...) repose-t-elle pas sur une expérience nécessairement pré-compréhensive et donc potentiellement illusoire? Or, c’est précisément parce qu’elle surmonte cette triple difficulté que la philosophie bergsonienne peut apparaître, par le renouvellement du sens qu’elle accorde à la liberté, comme une authentique doctrine de la libération.

A popular argument against direct duties for individuals to address climate change holds that only states and other powerful collective agents must act. It excuses individual actions as harmless since they are neither necessary nor sufficient to cause harm, arise through normal activity, and have no clear victims. Philosophers have challenged one or more of these assumptions; however, I show that this definition of harm also excuses states and other collective agents. I cite two examples of this in public discourse (...) and suggest we reconsider the notion of harmful action in our discussions about climate change. (shrink)

Over the last decade, more U.S. taxpayers money has been spent trying to anticipate and address the bioethical issues raised by advances in human genetics than any other set of issues in the field. Does this make sense? Not everyone in bioethics thinks so. Some think there are more important topics, like issues of health care justice, that will be neglected if the field continues to follow the money to dwell on the moral challenges of a relatively small community of (...) research scientists. Others decry genetic exceptionalism as inappropriately singling out this scientific enterprise for criticism and regulation, when the same issues are faced even more acutely in other parts of the biomedical world. Human genetics is not accelerating as fast as pharmacology, for example, or as easy to abuse as virology, or as philosophically challenging as neurology. (shrink)

I argue that recent evidence about our self-serving biases has radical implications for the epistemology of peer disagreement. I conclude that much of the time when you are disagreeing with someone you regard as your epistemic peer, you should not merely move halfway to her judgment, as The Equal Weight View has it. That is not conciliatory enough. Surprisingly often, you should be at least weakly confident that you are wrong, and that your disputant is right.

There is now a considerable body of published work on the epistemology of modern chemistry, especially with regard to the nature of quantum chemistry. In addition, the question of the metaphysical underpinnings of chemistry has received a good deal of attention. The present article concentrates on metaphysical considerations including the question of whether elements and groups of elements are natural kinds. It is also argued that an appeal to the metaphysical nature of elements can help clarify the re-emerging controversies among (...) chemists regarding the placement of the elements hydrogen and helium in the periodic system and the question of whether there exists a best form of the periodic table.

This essay examines the connection between the concept of autonomy and the concept of an ideal, moral self in Kant’s practical philosophy. Its central thesis is that self-legislation does not rest on the capacity to exempt oneself from nature’s causal network. Instead, it rests on the practical capacity for identification with what Kant calls an individual’s “moral personality.” A person’s ability to identify with this morally ideal version of himself gives shape to his will, enabling him to decide how to (...) act on the basis of reasons that do not stem from desires or inclinations. It thus makes possible a form of volition that is autonomous rather than heteronomous. (shrink)

In this article I report findings from interviews with 26 openly gay male athletes who came out between 2008 and 2010. I compare their experiences to those of 26 gay male athletes who came out between 2000 and 2002. The athletes in the 2010 cohort have had better experiences after coming out than those in the earlier cohort, experiencing less heterosexism and maintaining better support among their teammates. I place these results in the context of inclusive masculinity theory, suggesting that (...) local cultures of decreased homophobia created more positive experiences for the 2010 group. (shrink)

Bernard Williams argued that philosophers should pay more attention to the role thick ethical concepts play in our moral thinking, and, separately, that all reasons for action depend in the first place upon the agent's pre-exisitng motives. Here I argue that these two views are in tension. Much like the standard examples of thick ethical concepts, the concept REASONABLE is likewise thick, and the features of the world that guide its correct use have much less to do with the agent's (...) pre-existing motives than internalism about reasons for action maintains.

Pour justifier leur activité, les premiers mercantilistes anglais présentent le commerce comme une activité naturelle, qui favorise la paix entre les nations et contribue au progrès de la civilisation. Ils ont en particulier recours à la lex mercatoria, notion héritée du Moyen Âge. L’idée d’un commerce mutuel de l’humanité, mise en avant dans les écrits de marchands, mais également chez un auteur comme Grotius, contraste ainsi avec les théories de la souveraineté liée à un territoire national chez des penseurs politiques (...) comme Francis Bacon, Thomas Hobbes et William Petty, ou à certains égards chez un juriste comme John Selden. Paradoxalement, alors que la constitution des empires coloniaux coïncide avec l’essor du grand négoce international, la liberté du commerce (free trade) est présentée par ses défenseurs comme une alternative à l’antagonisme entre les États et à la logique de domination induite par les théories modernes de l’imperium. Cette apparente contradiction entre la logique étatique et l’humanisme marchand – ou ce qui se présente comme tel – semble subsister dans les résurgences modernes de la lex mercatoria au XXe siècle. Pourtant, l’idée d’une source du droit indépendante de l’État et s’enracinant dans l’ancienneté des coutumes, l’uniformité des pratiques marchandes ou encore le jus gentium, relève en grande partie de la fable, et d’une construction idéologique visant à dissimuler la réalité des pratiques commerciales. De ce point de vue, la fable de la lex mercatoria joue très certainement un rôle important dans la constitution du topos du doux commerce et la promotion de la liberté des échanges par ceux qui en sont, directement ou indirectement, les principaux bénéficiaires.

The ancient Chinese philosopher Zhuangzi defies coherent interpretation. This is an inextricable part of the beauty and power of his work. The text – by which I mean the “Inner Chapters” of the text traditionally attributed to him, the authentic core of the book – is incomprehensible as a whole. It consists of shards, in a distinctive voice – a voice distinctive enough that its absence is plain in most or all of the “Outer” and “Miscellaneous” Chapters, and which I (...) will treat as the voice of a single author. Despite repeating imagery, ideas, style, and tone, these shards cannot be pieced together into a self-consistent philosophy. This lack of self-consistency is a positive feature of Zhuangzi. It is part of what makes him the great and unusual philosopher he is, defying reduction and summary. (shrink)

The Homeric epics are among the greatest masterpieces of literature, but when they were produced is not known with certainty. Here we apply evolutionary-linguistic phylogenetic statistical methods to differences in Homeric, Modern Greek and ancient Hittite vocabulary items to estimate a date of approximately 710–760 BCE for these great works. Our analysis compared a common set of vocabulary items among the three pairs of languages, recording for each item whether the words in the two languages were cognate – derived from (...) a shared ancestral word – or not. We then used a likelihood-based Markov chain Monte Carlo procedure to estimate the most probable times in years separating these languages given the percentage of words they shared, combined with knowledge of the rates at which different words change. Our date for the epics is in close agreement with historians' and classicists' beliefs derived from historical and archaeological sources. (shrink)

How do you know your own beliefs? And how well do you know them? The two questions are related. I’ll recommend a pluralist answer to the first question. The answer to the second question, I’ll suggest, varies depending on features of the case.

I examine several leading neuronal accounts of binding and conclude that, while those neuronal accounts might be necessary in some important senses (e.g., when it comes to error minimization), they fail to provide satisfying solutions to the hard problems of unified experience. I then present a new, testable hypothesis called emergent subject dualism to account for the unity of experience across modalities of the brain.

This paper investigates whether there is an acceptable version of Functionalism that avoids commitment to second-order properties. I argue that the answer is "no". I consider two reductionist versions of Functionalism, and argue that both are compatible with multiple realization as such. There is a more specific type of multiple realization that poses difficulties for these views, however. The only apparent Functionalist solution is to accept second-order properties.
