Recent debate in metaethics over evolutionary debunking arguments against morality has shown a tendency to abstract away from relevant empirical detail. Here, I engage the debate about Darwinian debunking of morality with relevant empirical issues. I present four conditions that must be met in order for it to be reasonable to expect an evolved cognitive faculty to be reliable: the environment, information, error, and tracking conditions. I then argue that these conditions are not met in the case of our evolved (...) faculty for moral judgement. (shrink)

According to higher-order theories of consciousness, a mental state is conscious only when represented by another mental state. Higher-order theories must predict there to be some brain areas (or networks of areas) such that, because they produce (the right kind of) higher-order states, the disabling of them brings about deficits in consciousness. It is commonly thought that the prefrontal cortex produces these kinds of higher-order states. In this paper, I first argue that this is likely correct, meaning that, if some (...) higher-order theory is true, prefrontal lesions should produce dramatic deficits in visual consciousness. I then survey prefrontal lesion data, looking for evidence of such deficits. I argue that no such deficits are to be found, and that this presents a compelling case against higher-order theories.

One reason that many philosophers are reluctant to seriously contemplate the possibility that we lack free will seems to be the view that we must believe we have free will if we are to regard each other as persons in the morally deep sense—the sense that involves deontological notions such as human rights. In the contemporary literature, this view is often informed by P.F. Strawson's view that to treat human beings as having free will is to respond to them with (...) the reactive attitudes, and that if we suspend the reactive attitudes we can only regard human beings as objects to be manipulated in the service of social goals. This purported implication of suspending the reactive attitudes has persuaded many philosophers that we cannot truly treat human beings as persons without assuming that they have free will. I argue that this line of thinking is misguided. I think Strawson is correct to worry that the consequentialism he sees as implicit in the objective attitude undermines our ability to treat each other as persons. But I think it is a mistake to accept that we must maintain the reactive attitudes, or any other attributions of free will or moral responsibility, to avoid a depersonalizing slide into consequentialism. Kant's idea of treating people as autonomous ends in themselves, rather than as mere means to ends, provides a compelling analysis of what it means to treat humans as persons, and I argue that there are ways of interpreting Kant's idea which do not involve reactive attitudes or any other attributions of free will or moral responsibility. -/- .

What does it mean that some proposition follows from others? The standard way of spelling out the notion proceeds in modal terms: x follows from y iff necessarily, if y is true, so is x. But although this yields a useful and manageable account of consequence, it fails to capture certain aspects of our pre-theoretical understanding of consequence. In this paper, an alternative notion of logical consequence, based on the idea of grounding, is developed.

Bioethicists’ views diverge public opinion on various ethical issues, particularly in healthcare. For instance, bioethicists generally oppose payment for organs and advocate for preventing death at any age, whereas the public is more supportive of organ payment and prioritizing younger patients. I offer four arguments on how best to view this divergence. (a) Bioethicists’ specialized training, objectivity, and reliance on research often lead to views that differ from those of the public, which may be less informed and more influenced by (...) biases. (b) Further, divergence between expert and public opinion is a normal and sometimes necessary aspect of bioethics. Divergence can lead to more informed and progressive ethical practices. (c) While public input is valuable, achieving meaningful engagement is difficult due to varying values, risk perceptions, and socioeconomic circumstances. Effective bioethics would balance expert knowledge with public input, aiming for policies that are both scientifically sound and democratically legitimate. (d) Maintaining public trust in bioethics does not require full alignment with public opinion. Instead, bioethicists should focus on educating the public and incorporating informed public perspectives into their analysis and recommendations. (shrink)

The COVID-19 pandemic has generated an imbalance between the clinical needs of the population and the effective availability of advanced life support (ALS) resources. Triage protocols have thus become necessary. Triage decisions in situations of scarce resources were not extraordinary in the pre-COVID-19 era; these protocols abounded in the context of organ transplantation. However, this prior experience was not considered during the COVID-19 outbreak in Spain. Lacking national guidance or public coordination, each hospital has been forced to put forth independent (...) and autonomous triage protocols, most of which were, nonetheless, based on common ethical principles and clinical criteria. However, controversial, non-clinical criteria have also been defended by Spanish scientific societies and public institutions, including setting an age cut-off value for unilaterally withholding ALS, using ‘social utility’ criteria, prioritising healthcare professionals or using ‘first come, first served’ policies. This paper describes the most common triage criteria used in the Spanish context during the COVID-19 epidemic. We will highlight our missed opportunities by comparing these criteria to those used in organ transplantation protocols. The problems posed by subjective, non-clinical criteria will also be discussed. We hope that this critical review might be of use to countries at earlier stages of the epidemic while we learn from our mistakes. (shrink)

Radical virtue serves two distinct purposes: consolation in unfavorable circumstances, and prescription to achieve better ones. This paper maps out the theoretical nuances important for practical guidance. For a Stoic, radical virtue is a way to live well through environmental tragedy. For a consequentialist, it is an instrument to motivate us to combat climate change. For an Aristotelian, it is both. I argue that an Aristotelian approach fares the best, balancing the aim of external success with the aim of living (...) well through practical wisdom. This involves criticizing assumptions about living well that underlie behaviors that contribute to climate change. Some might object virtue theory suffers from application problems, and an Aristotelian approach suffers even more because it does not tell the virtuous person how to negotiate her aims. In response, Aristotelian revision starts with moral perception that adds valuable content by navigating through the messiness. (shrink)

Following Cass Sunstein's popular treatment of the concept, echo chambers are often defined as environments which exclude contrary opinions through omission. C. Thi Nguyen contests the popular usage and defines echo chambers in terms of in-group trust and out-group distrust. In this paper, I argue for a more comprehensive treatment. While both exclusion by omission and out-group distrust help sustain echo chambers, neither defines the phenomenon. I develop a social network model of echo chambers which focuses on the role of (...) belief-reinforcing echoes. First, I argue that the model allows us to incorporate Nguyen's main point about distrust without construing other commentators as deeply mistaken about the nature of echo chambers. Second, I use the model to develop an account of collaborative resistance and use it to clarify the role echo chambers play in spreading misinformation. (shrink)

Diagrams have distinctive characteristics that make them an effective medium for communicating research findings, but they are even more impressive as tools for scientific reasoning. Focusing on circadian rhythm research in biology to explore these roles, we examine diagrammatic formats that have been devised to identify and illuminate circadian phenomena and to develop and modify mechanistic explanations of these phenomena.

The authors put forward an interesting response to detractors of black box algorithms. According to the authors, what is of ethical relevance for medical artificial intelligence is not so much their transparency, but rather their reliability as a process capable of producing accurate and trustworthy results. The implications of this view are twofold. First, it is permissible to implement a black box algorithm in clinical settings, provided the algorithm’s epistemic authority is tempered by physician expertise and consideration of patient autonomy. (...) Second, physicians are not expected to possess exhaustive knowledge or understanding of the algorithmic computation by which they verify or augment their medical opinions. The potential of these algorithms to improve diagnostic and procedural accuracy alongside the quality of patient decision-making is undoubtedly a boon to modern medicine, but blind deference to them is neither feasible nor responsible, as several logistical and ethical quagmires noted by the authors still remain inherent in algorithmic software. I concur …. (shrink)

According to orthodoxy, there are two basic moods of supposition: indicative and subjunctive. The most popular formalizations of the corresponding norms of suppositional judgement are given by Bayesian conditionalization and Lewisian imaging, respectively. It is well known that Bayesian conditionalization can be generalized (via Jeffrey conditionalization) to provide a model for the norms of partial indicative supposition. This raises the question of whether imaging can likewise be generalized to model the norms of ‘partial subjunctive supposition’. The present article casts doubt (...) on whether the most natural generalizations of imaging are able to provide a plausible account of the norms of partial subjunctive supposition. (shrink)

The chief goal of Velmans' article is to find a way to solve the problem of how conscious experience could have bodily effects. I shall discuss his treatment of this below. First, I would like to deal with Velmans' treatment of my own studies of volition and free will in relation to brain processes. Unconscious Initiation and Conscious Veto of Freely Voluntary Acts Velmans appropriately refers to our experimental study that found that onset of an electrically observable cerebral process preceded (...) the appearance of the subject's awareness of the conscious wish to act, by at least 350 msec. That indicated that the volitional process is initiated unconsciously. Velmans uses the term preconscious instead of unconscious. But, in fact, subjects have no reportable awareness or intuitive feeling that the brain has started a process before their conscious wish/urge to act appears. Unconscious initiation of the voluntary process appeared to mean that conscious free will could not actually 'tell' the brain to begin its preparation to carry out a voluntary act. (shrink)

The first philosophers of the Frankfurt School famously turned to the psychoanalytic theories of Sigmund Freud to supplement their Marxist analyses of ideological subjectification. Since the collapse of their proposed "marriage of Marx and Freud," psychology and social theory have grown apart to the impoverishment of both. Returning to this union, Benjamin Y. Fong reconstructs the psychoanalytic "foundation stone" of critical theory in an effort to once again think together the possibility of psychic and social transformation. Drawing on the (...) work of Hans Loewald and Jacques Lacan, Fong complicates the famous antagonism between Eros and the death drive in reference to a third term: the woefully undertheorized drive to mastery. Rejuvenating Freudian metapsychology through the lens of this pivotal concept, he then provides fresh perspective on Theodor Adorno, Max Horkheimer, and Herbert Marcuse's critiques of psychic life under the influence of modern cultural and technological change. The result is a novel vision of critical theory that rearticulates the nature of subjection in late capitalism and renews an old project of resistance. (shrink)

It is usually thought that wrongful acts of threat-involving coercion are wrong because they involve a violation of the freedom or autonomy of the targets of those acts. I argue here that this cannot possibly be right, and that in fact the wrongness of wrongful coercion has nothing at all to do with the effect such actions have on their targets. This negative thesis is supported by pointing out that what we say about the ethics of threatening (and thus the (...) ethics of coercion) constrains what we can say about the ethics of warning and offering. Importantly, our favoured explanation of the wrongness of certain kinds of threatening should not commit us to condemning as wrong parallel cases of warning and offering. My positive project is to show how this can be done. I defend the claim that wrongful coercion is nothing more than the issuing of a conditional threat to do wrong, and that an agent's issuing of a conditional threat to do wrong is wrong because it constitutes motivation for that agent to adopt the announced intention to do wrong. The idea of explaining the wrongness of wrongful coercion in this way has gone unnoticed because we have thus far been mistaken about what a threat is. In this essay I present my moral analysis of coercion only after presenting a careful descriptive analysis of threats. On my view, it is essential to a threat that the announced intention is one that the agent does not possess before announcing it. This analysis makes it possible to elucidate the descriptive differences between threats, warnings and offers, which sets up the later project of elucidating the moral differences between them.

Despite their centrality to the scientific enterprise, both the nature of scientific variables and their relation to inductive inference remain obscure. I suggest that scientific variables should be viewed as equivalence classes of sets of physical states mapped to representations (often real numbers) in a structure preserving fashion, and argue that most scientific variables introduced to expand the degrees of freedom in terms of which we describe the world can be seen as products of an algorithmic inductive inference first identified (...) by William W. Rozeboom. This inference algorithm depends upon a notion of natural kind previously left unexplicated. By appealing to dynamical kinds—equivalence classes of causal system characterized by the interventions which commute with their time evolution—to fill this gap, we attain a complete algorithm. I demonstrate the efficacy of this algorithm in a series of experiments involving the percolation of water through granular soils that result in the induction of three novel variables. Finally, I argue that variables obtained through this sort of inductive inference are guaranteed to satisfy a variety of norms that in turn suit them for use in further scientific inferences.

Each had met his match, and happily, in the other. This book is the story of an elective affinity.

It is often said that clinical research and the practice of medicine are fraught with uncertainties. But what do we mean by uncertainty? Where does uncertainty come from? How do we measure uncertainty? Is there a single theory of uncertainty that applies across all scientific domains, including the science and practice of medicine? To answer these questions, we first review the existing theories of uncertainties. We then attempt to bring the enormous literature to bear from other disciplines to address the (...) issue of uncertainty in clinical research and medical practice. Our main and overarching goal is to review and classify uncertainties in clinical medicine. (shrink)

In response to the racial disparities that plague the American criminal justice system, the Movement for Black Lives calls for an end to policing and punishment “as we know it.” But refusing to punish violent offenses leaves unprotected those most vulnerable to crime, and outright abolition thus appears to undermine black rights and liberties. I call this the decarceration dilemma. After discussing Tommie Shelby and Christopher Lewis’s attempts to resolve the dilemma, I offer my own, which employs a procedural rather (...) than a substantive solution. I lean on the principle of expanded asymmetry (EA), which holds that it is better to underpunish than overpunish. After defending EA, I note that it obtains only under conditions of uncertainty. I then show that because virtually all trials of black offenders meet the uncertainty condition, sentencing authorities are obliged to treat black offenders leniently. I conclude by noting the advantages of my proceduralist approach. (shrink)

The current research investigates the interaction between thought suppression and individuals’ explicit awareness of their thoughts. Participants in three experiments attempted to suppress thoughts of a prior romantic relationship and their success at doing so was measured using a combination of self-catching and experience-sampling. In addition to thoughts that individuals spontaneously noticed, individuals were frequently caught engaging in thoughts of their previous partner at experience-sampling probes. Furthermore, probe-caught thoughts were: associated with stronger decoupling of attention from the environment, more likely (...) to occur under cognitive load, more frequent for individuals with a desire to reconcile, and associated with individual differences in the tendency to suppress thoughts. Together, these data suggest that individuals can lack meta-awareness that they have begun to think about a topic they are attempting to suppress, providing novel insight into the cognitive processes that are involved in attempting to control undesired mental states.

In response to the problem of Hell, Buckareff and Plug (Relig Stud 41:39–54, 2005; Relig Stud 45:63–72, 2009) have recently proposed and defended an ‘escapist’ conception of Hell. In short, they propose that the problem of Hell does not arise because God places an open-door policy on Hell. In this paper, I expose a fundamental problem with this conception of Hell—namely, that if there’s an open door policy on Hell, then there should be one on Heaven too. I argue that (...) a coherent conception of Heaven cannot have such a policy. Hence, escapism is not an adequate response to the problem of Hell. (shrink)

It is widely believed that platonists face a formidable problem: that of providing an intelligible account of mathematical knowledge. The problem is that we seem unable, if the platonist is right, to have the causal relationships with the objects of mathematics without which knowledge of these objects seems unintelligible. The standard platonist response to this challenge is either to deny that knowledge without causation is unintelligible, or to make room for causal interactions by softening the platonism at issue. In this (...) essay I argue that the idea of causal relations with fully platonist objects is unproblematic. (shrink)

During the 2020 COVID-19 pandemic, open science has become central to experimental, public health, and clinical responses across the globe. Open science is described as an open commons, in which a right to science renders all possible scientific data for everyone to access and use. In this common space, capitalist platforms now provide many essential services and are taking the lead in public health activities. These neoliberal businesses, however, have a problematic role in the capture of public goods. This paper (...) argues that the open commons is a community of rights, consisting of people and institutions whose interests mutually support the public good. If OS is a cornerstone of public health, then reaffirming the public good is its overriding purpose, and unethical platforms ought to be excluded from the commons and its benefits. (shrink)

This article addresses the problematic perspectives of drone culture. In critiquing focus on the drone’s apparent ‘autonomy’, it argues that such devices function as part of a socio-technical network. They are relational parts of human–machine interaction that, in our changing geopolitical realities, have a powerful influence on politics, reputation and warfare. Drawing on Žižek’s conception of parallax, the article stresses the importance of culture and perception in forming the role of the drone in widening power asymmetries. It examines how perceptions (...) of autonomy are evoked by drones, to claim that this misperception is a smokescreen that obscures the relational socio-technical realities of the drone. The article therefore argues that a more critical culture of the drone emerges by shifting the focus and perception from autonomy to anonymity. This allows us to engage more fully with the distributed agency and decision-making that define how drones are developed and deployed. Rather than focusing on the drone as a singular, fetishised, technical object, a relational approach to the drone assemblage is proposed that highlights the competing human interests that define and resist drones in global politics and culture.

In this article, I focus on what is we know when we know pain or that someone is in pain. I argue that claims of knowledge about pains are problematic because of the complex nature of the phenomenon and because of "pain" is a cluster concept.

The possibility of cooperation and the stability of political order are long-standing problems. Polybius, well known for his Histories analysing the expansion of Rome and his description of the Roman constitution, also offers an intriguing social and political theory that covers ground from psycho-anthropological micro-foundations to institution-based political order, providing a genealogy of morals and political order that is best understood in game-theoretical terms. In this paper I try to give such an interpretation. Polybius’ naturalistic, proto-game theoretical views show similarities (...) with Hume, Smith and especially Hobbes’ doctrine of sovereignty by acquisition. However, Polybius is original in crucial regards, giving a motivationally plausible account of institutional and especially constitutional solutions to moral and political problems. Constitutional order, for Polybius, embodies and makes possible in the first place a kind of political reason that cannot be had individually. Polybian political theory thus offers interesting solutions to problems concerning moral motivation, collective action, and the conditions for political order, as well as the explanation and character of institutions.

We report on the development and initial validation of the Moralization of Everyday Life Scale, designed to measure variations in people's assignment of moral weight to commonplace behaviors. In Study 1, participants reported their judgments for a large number of potential moral infractions in everyday life; principal components analysis revealed 6 main dimensions of these judgments. In Study 2, scores on the 30-item MELS showed high reliability and distinctness from the Big 5 personality traits. In Study 3, scores on the (...)

The fragmentary state of Cicero’s De Republica makes it difficult to see how it is a unified work. In this article, I argue that Cicero uses ring composition to unify the dialogue as a polemic against the Epicurean prohibition on political involvement. Cicero is following Plato in his use of ring composition, and just as Plato uses ring composition in the Republic to express his views about philosophical method, so does Cicero. Ring composition turns out to be central to a (...) plausible skeptical reading of the De Republica, in which Cicero both tries to induce suspension of belief in the Epicurean prohibition on political involvement, as well as prevent the reader from unreflectively adopting his own provisionally held views, both consistent with his commitment to the pedagogical aims of Academic skeptical philosophy.

What is wrong with colonialism? The standard—albeit often implicit—answer to this question has been that colonialism was wrong because it violated the territorial rights of indigenous peoples, where territorial rights were grounded on acquisition theories. Recently, the standard view has come under attack: according to critics, acquisition based accounts do not provide solid theoretical grounds to condemn colonial relations. Indeed, historically they were used to justify colonialism. Various alternative accounts of the wrong of colonialism have been developed. According to some, (...) colonialism involved a violation of territorial rights grounded on legitimate state theory. Others reject all explanations of colonialism's wrongfulness based on territorial rights, and argue that colonial practices were wrong because they departed from ideals of economic, social, and political association. In this article, we articulate and defend the standard view against critics: colonialism involved a procedural wrong; this wrong is not the violation of standards of equality and reciprocity, but the violation of territorial rights; and the best foundation for such territorial rights is acquisition based, not legitimacy based. We argue that this issue is not just of historical interest, it has relevant implications for the normative evaluation of contemporary inequalities. (shrink)

This article argues for reading the Algerian-French sociologist Abdelmalek Sayad (1933–1998) as a political theorist of migration. Various contributions have recently called to move away from the court-like assessment of claims by host states and foreigners and to engage more frankly with empirical work more attentive to concrete experiences and power relations. I contend that Sayad’s sociological work constitutes a substantial empirical and normative resource for ethical and political theory of migration, pointing to the persistence of ‘state thought’ and presenting (...) original normative perspectives on emigration, inclusion in democracy, naturalization or postcolonial relationships. Such a reading of Sayad from a political theory perspective would then constitute a prime example of the cross-fertilization of empirical and normative approaches. (shrink)

According to proponents of the generalized magnitude system proposal (GMS), SNARC-like effects index spatial mappings of magnitude and provide crucial evidence for the existence of a GMS. Casasanto and Pitt (2019) have argued that these effects, instead, reflect mappings of ordinality, which people compute on the basis of differences among stimuli that vary either qualitatively (e.g., musical pitches) or quantitatively (e.g., dots of different sizes). In response to our paper, Prpic et al. (2021) argued that both magnitude and ordinality play (...) a role in SNARC-like effects. Here, we address each of their arguments and conclude that magnitude is relevant to these effects only insofar as it serves as a basis for ordinality. For this reason and others, SNARC or SNARC-like effects cannot provide evidence for the putative generalized magnitude system. (shrink)

It is often thought that an agent is blameworthy only for wrongdoing she had a fair opportunity to avoid. However, in this article, I defend the thesis that there is a form of culpability for wrongdoing—exemplified by criminal guilt—that it is possible to accrue even for wrongdoing one lacked a fair opportunity to avoid. If I am right that criminal guilt, properly conceived, is not something everyone necessarily has a fair opportunity to avoid, an offender’s lack of fair opportunity to (...) avoid her guilt would appear to be an important potential ground for mitigation at sentencing. Hence, the thesis of this article may point the way toward a novel explanation of a moral intuition that a coterie of moral, political, and legal theorists has for decades sought but struggled to vindicate: the intuition that offenders who have suffered from various social disadvantages should receive less punishment for their crimes, even when those crimes are not morally justified or excused.

Research in penalty kicking has primarily focused on spatial decision making, while temporal decision making has largely been neglected, even though it is as critical for success. Temporal decision making concerns goalkeepers choosing when to initiate their jump to the ball during the penalty taker's run-up, and penalty takers deciding where to kick the ball, either prior to the run-up or after the goalkeeper has committed to one side. We analyzed penalty takers' and goalkeepers' behavior during penalty shoot-outs at FIFA (...) World Cups and UEFA European Championships to scrutinize if temporal aspects of decision making have an impact on penalty kick success. Results indicate that the likelihood of a penalty kick being scored depends on the combination of penalty takers' and goalkeepers' temporal decision-making strategies. Hence, moving early more often seems fruitful for goalkeepers, while penalty takers should consider varying penalty kick strategy between attempts. (shrink)

In this article, I defend the idea that Bentham's international political theory entails a cosmopolitan dimension. First, I explain that Bentham rejects two pillars of internationalism, namely, the sovereign's unconstrained autonomous power and authority in international politics, and the legal and moral personality of the state in the international realm. This critique leads Bentham to construct a complex international political theory which places the issue of states’ responsibility at its centre. Bentham's international theory articulates a minimalist international system of cooperation (...) between states and an institutional model of public officials’ responsibilities that together play the crucial role in securing the greatest happiness of the greatest number in the world. In this last part, I explain how Bentham's international political theory relies heavily on the responsibilities of states, a set of responsibilities that encompasses both national and cosmopolitan responsibilities that public officials in each state hold.

This paper discusses some formal properties of trivalent approaches to presupposition projection, and in particular of the middle Kleene system of Peters (1977) and Krahmer (1998). After exploring the relationship between trivalent truth-functional accounts and dynamic accounts in the tradition of Heim (1983), I show how the middle Kleene trivalent account can be formulated in a way which shows that it meets the explanatory challenge of Schlenker (2006, 2008a,b), and provide some results relating to the application of the middle Kleene (...) approach to generalised quantifiers.
