Our recent review demonstrates that “purity” is a messy construct with at least nine popular scientific understandings. Cultural beliefs about self-control help unify some of these understandings, but much messiness remains. The harm-centric theory of dyadic morality suggests that purity violations can be comprehensively understood as abstract harms, acts perceived by some people (and not others) to indirectly cause suffering.

Social and neurocognitive research suggests that thinking about one’s own thinking and thinking about the thinking of others—termed ‘mindreading’, ‘metacognition’, ‘social cognition’ or ‘mentalizing’ are not identical activities. The ability though to think about thinking in the first person is nevertheless related to the ability to think about other’s thoughts in the third person. Unclear is how these phenomena influence one another. In this review, we explore how self-reflection and autobiographical memory influence the capacity to think about the thoughts and (...) emotions of others. We review studies suggesting that the more individuals are able to reflect on and retrieve episodes from their life narratives, the more they are likely to grasp others’ thoughts and emotions. We discuss evidence supporting this possibility including studies of the neurocognitive bases of empathy and self-awareness and how different aspects of self-reflection may impact on mindreading. We also draw from clinical reports how improved self-reflection may result in a more nuanced mindreading, namely persons suffering from schizophrenia and narcissistic personality disorder. We finally discuss the implications for research and practice and consider whether there are conditions in which the reverse is true, where self-reflection might impair mindreading or in which mindreading may facilitate self-reflection.

Self-reflection plays a key role in healthy human adaptation. Self-reflection might involve different capacities which may be impaired to different degrees relatively independently of one another. Variation in abilities for different forms of self-reflection are commonly seen as key aspects of many adult mental disorders. Yet little has been written about whether there are different kinds of deficits in self-reflection found in mental illness, how those deficits should be distinguished from one another and how to characterize the extent to which (...) they are interrelated. We review clinical and experimental literature and suggest four different forms of deficits in self-reflection: sense of ownership of one’s own thoughts and actions, emotional awareness, distinction between fantasy and reality and the integration of a range of different views of oneself and others. We propose how these different impairments in self-reflection are linked with one another. (shrink)

How can we think about things in the outside world? There is still no widely accepted theory of how mental representations get their meaning. In light of pioneering research, Nicholas Shea develops a naturalistic account of the nature of mental representation with a firm focus on the subpersonal representations that pervade the cognitive sciences.

In mainstream analytic epistemology, Reformed theology has made its presence prominently felt in Reformed epistemology, the view of religious belief according to which religious beliefs can be properly basic and warranted when formed by the proper functioning of the sensus divinitatis, an inborn capacity or faculty for belief in God that can be prompted to generate certain religious beliefs when presented with things (e.g., certain majestic aspects of creation). A major competitor to Reformed epistemology is Wittgensteinian quasi-fideism, a position drawn (...) from the epistemology of Wittgenstein’s On Certainty, according to which some foundational religious commitments are not properly basic beliefs but some kind of apodictic, unshakeable certainties that form part of the structure of one’s rationality and worldview. I argue that the Reformed tradition has contained elements of quasi-fideism at least as far back as Calvin’s account of faith from the Institutes of the Christian Religion, book 3, chapter 2.

This volume is about abstract objects and the ways we refer to them in natural language. Asher develops a semantical and metaphysical analysis of these entities in two stages. The first reflects the rich ontology of abstract objects necessitated by the forms of language in which we think and speak. A second level of analysis maps the ontology of natural language metaphysics onto a sparser domain--a more systematic realm of abstract objects that are fully analyzed. This second level reflects the (...) commitments of real metaphysics. The models for these commitments assign truth conditions to natural language discourse.

Social scientists and computer scientist are divided by small differences in perspective and not by any significant disciplinary divide. In the field of text analysis, several such differences are noted: social scientists often use unsupervised models to explore corpora, whereas many computer scientists employ supervised models to train data; social scientists hold to more conventional causal notions than do most computer scientists, and often favor intense exploitation of existing algorithms, whereas computer scientists focus more on developing new models; and computer (...) scientists tend to trust human judgment more than social scientists do. These differences have implications that potentially can improve the practice of social science. (shrink)

Proposals to make us smarter than the greatest geniuses or to add thousands of years to our life spans seem fit only for the spam folder or trash can. And yet this is what contemporary advocates of radical enhancement offer in all seriousness. They present a variety of technologies and therapies that will expand our capacities far beyond what is currently possible for human beings. In _Humanity's End,_ Nicholas Agar argues against radical enhancement, describing its destructive consequences. Agar examines (...) the proposals of four prominent radical enhancers: Ray Kurzweil, who argues that technology will enable our escape from human biology; Aubrey de Grey, who calls for anti-aging therapies that will achieve "longevity escape velocity"; Nick Bostrom, who defends the morality and rationality of enhancement; and James Hughes, who envisions a harmonious democracy of the enhanced and the unenhanced. Agar argues that the outcomes of radical enhancement could be darker than the rosy futures described by these thinkers. The most dramatic means of enhancing our cognitive powers could in fact kill us; the radical extension of our life span could eliminate experiences of great value from our lives; and a situation in which some humans are radically enhanced and others are not could lead to tyranny of posthumans over humans.

In this article, I argue that kinship implicitly operates as a normative ethical concept in Christine Korsgaard's account of animal ethics. I begin with an examination of the key theoretical foundations of Korsgaard's account and then examine the ways kinship operates as an ethical concept in her account, arguing that the ethical obligations she discusses are fundamentally grounded in a recognition of kinship with other animals. I conclude by recognizing that there are many remaining questions about kinship and animal ethics (...) but that the concept holds significant potential for thinking about the ethical obligations that we have to nonhuman animals.

Some opponents of abortion claim that fetuses are persons from the moment of conception. Following Berg (2017), let us call these individuals “Personhood-At-Conception” (or PAC), opponents of abortion. Berg argues that if fetuses are persons from the moment of conception, then miscarriage kills far more people than abortion. As such, PAC opponents of abortion face the following dilemma: They must “immediately” and “substantially” shift their attention, resources, etc., toward preventing miscarriage or they must admit that they do not actually believe (...) that fetuses are persons from the moment of conception (or, at least, they must recognize that they are not acting in ways that are consistent with this belief). In this essay, I show that Berg’s argument fails at each step. Specifically, after outlining her argument (in section 1), I consider the central claim of Berg’s style of argument: That “miscarriage…is much deadlier than abortion.” In section 2, I argue that this claim is false (when taken literally) and misleading otherwise. In section 3, I show that Berg’s style of argument is identical in structure to a criticism that is sometimes levied against the recent “Black Lives Matter” movement. In the latter context, the argument has been vehemently rejected. I argue that Berg’s style of argument should be rejected for the same reasons. Finally, in section 4, I show that Berg’s suggestion that opponents of abortion should divert “substantial” amounts of money and attention to miscarriage prevention faces two problems. First, these claims are made without any evidence regarding the actual priorities and spending habits of PAC opponents of abortion. If we are told “not enough is being done,” one wonders: What is being done and how much counts as “enough”? Berg gives no answer to either question. Second, even if it is true that opponents of abortion do not pay substantial attention to miscarriage prevention, Berg fails to notice that this may be for good reason. I conclude that PAC opponents of abortion do not face the dilemma that Berg presents. (shrink)

Opponents of abortion are often described as ‘inconsistent’ (hypocrites) in terms of their beliefs, actions and/or priorities. They are alleged to do too little to combat spontaneous abortion, they should be adopting cryopreserved embryos with greater frequency and so on. These types of arguments—which we call ‘inconsistency arguments’—conform to a common pattern. Each specifies what consistent opponents of abortion would do (or believe), asserts that they fail to act (or believe) accordingly and concludes that they are inconsistent. Here, we show (...) that inconsistency arguments fail en masse. In short, inconsistency arguments typically face four problems. First, they usually fail to account for diversity among opponents of abortion. Second, they rely on inferences about consistency based on isolated beliefs shared by some opponents of abortion (and these inferences often do not survive once we consider other beliefs opponents of abortion tend to hold). Third, inconsistency arguments usually ignore the diverse ways in which opponents of abortion might act on their beliefs. Fourth, inconsistency arguments criticise groups of people without threatening their beliefs (eg, that abortion is immoral). Setting these problems aside, even supposing inconsistency arguments are successful, they hardly matter. In fact, in the two best-case scenarios—where inconsistency arguments succeed—they either encourage millions of people to make the world a (much) worse place (from the critic’s perspective) or promote epistemically and morally irresponsible practices. We conclude that a more valuable discussion would be had by focusing on the arguments made by opponents of abortion rather than opponents themselves. (shrink)

A clearly written, authoritative introduction to Taylor's work.

Socrates' attitude towards falsehood is quite puzzling in the Republic. Although Socrates is clearly committed to truth, at several points he discusses the benefits of falsehood. This occurs most notably in Book 3 with the "noble lie" (414d-415c) and most disturbingly in Book 5 with the "rigged sexual lottery" (459d-460c). This raises the question: What kinds of falsehoods does Socrates think are beneficial, and what kinds of falsehoods does he think are harmful? And more broadly: What can this tell us (...) about the relationship between ethics and epistemology? The key to answering these questions lies in an obscure and paradoxical passage in Book II; at 382a-d Socrates distinguishes between "true falsehoods" and "impure lies." True falsehoods are always bad, but impure lies are sometimes beneficial. Despite Socrates' insistence that he is not saying anything deep, his distinction is far from straightforward. Nevertheless, in order to determine why some falsehoods are beneficial and why some are always harmful, we must understand what exactly true falsehoods are and how they differ from impure lies. In this paper, I argue that true falsehoods are a restricted class of false beliefs about ethics; they are false beliefs about how one should live and what one should pursue. I refer to these beliefs as "normative commitments." False normative commitments are always pernicious because they create and sustain psychological disharmony. Unlike true falsehoods, impure lies can be about anything. Nevertheless, they are only beneficial when they help produce and sustain true normative commitments. I argue that the upshot of this is that practical concerns have a kind of primacy over theoretical concerns. (shrink)

BackgroundAmidst expanding roles in education and policy making, questions have been raised about the ability of Clinical Ethics Committees (CEC) s to carry out effective ethics consultations (CECons). However recent reviews of CECs suggest that there is no uniformity to CECons and no effective means of assessing the quality of CECons. To address this gap a systematic scoping review of prevailing tools used to assess CECons was performed to foreground and guide the design of a tool to evaluate the quality (...) of CECons.MethodsGuided by Levac et al’s (2010) methodological framework for conducting scoping reviews, the research team performed independent literature reviews of accounts of assessments of CECons published in six databases. The included articles were independently analyzed using content and thematic analysis to enhance the validity of the findings.ResultsNine thousand sixty-six abstracts were identified, 617 full-text articles were reviewed, 104 articles were analyzed and four themes were identified – the purpose of the CECons evaluation, the various domains assessed, the methods of assessment used and the long-term impact of these evaluations.ConclusionThis review found prevailing assessments of CECons to be piecemeal due to variable goals, contextual factors and practical limitations. The diversity in domains assessed and tools used foregrounds the lack of minimum standards upheld to ensure baseline efficacy.To advance a contextually appropriate, culturally sensitive, program specific assessment tool to assess CECons, clear structural and competency guidelines must be established in the curation of CECons programs, to evaluate their true efficacy and maintain clinical, legal and ethical standards.

Are bacteriophage T4 and the long-nosed elephant fish valuable in their own right? Nicholas Agar defends an affirmative answer to this question by arguing that anything living is intrinsically valuable. This claim challenges received ethical wisdom according to which only human beings are valuable in themselves. The resulting biocentric or life-centered morality forms the platform for an ethic of the environment. -/- Agar builds a bridge between the biological sciences and what he calls "folk" morality to arrive at a (...) workable environmental ethic and a new spectrum--a new hierarchy--of living organisms. The book overturns common-sense moral belief as well as centuries of philosophical speculation on the exclusive moral significance of humans. Spanning several fields, including philosophy of psychology, philosophy of science, and other areas of contemporary analytic philosophy, Agar analyzes and speaks to a wide array of historic and contemporary views, from Aristotle and Kant, to E. O. Wilson, Holmes Rolston II, and Baird Callicot. The result is a challenge to prevailing definitions of value and a call for a scientifically-informed appreciation of nature. (shrink)

This paper examines Plato’s conception of shame and the role intoxication plays in cultivating it in the Laws. Ultimately, this paper argues that there are two accounts of shame in the Laws. There is a public sense of shame that is more closely tied to the rational faculties and a private sense of shame that is more closely tied to the non-rational faculties. Understanding this division between public and private shame not only informs our understanding of Plato’s moral psychology, but (...) his political and ethical theory as well. (shrink)

Regarding the appropriateness of deception in clinical practice, two (apparently conflicting) claims are often emphasised. First, that ‘clinicians should not deceive their patients.’ Second, that deception is sometimes ‘in a patient’s best interest.’ Recently, Hardman has worked towards resolving this conflict by exploring ways in which deceptive and non-deceptive practices extend beyond consideration of patients’ beliefs. In short, some practices only seem deceptive because of the (common) assumption that non-deceptive care is solely aimed at fostering true beliefs. Non-deceptive care, however, (...) relates to patients’ non-doxastic attitudes in important ways as well. As such, Hardman suggests that by focusing on belief alone, we sometimes misidentify non-deceptive care as ‘deceptive’. Further, once we consider patients’ beliefs and non-doxastic attitudes, identifying cases of deception becomes more difficult than it may seem. In this essay, I argue that Hardman’s reasoning contains at least three serious flaws. First, his account of deception is underdeveloped, as it does not state whether deception must be intentional. The problem is that if intention is not required, absurd results follow. Alternatively, if intention is required, then identifying cases of deception will be much easier (in principle) than Hardman suggests. Second, Hardman mischaracterises the ‘inverse’ of deceptive care. Doing so leads to the mistaken conclusion that common conceptions of non-deceptive care are unjustifiably narrow. Third, Hardman fails to adequately separate questions about deception from questions about normativity. By addressing these issues, however, we can preserve some of Hardman’s most important insights, although in a much simpler, more principled way. (shrink)

Legal theorists are familiar with John Finnis's book Natural Law and Natural Rights, but usually overlook his interventions in US constitutional debates and his membership of a group of conservative Catholic thinkers, the 'new natural lawyers', led by theologian Germain Grisez. In fact, Finnis has repeatedly advocated conservative positions concerning lesbian and gay rights, contraception and abortion, and his substantive moral theory derives from Grisez. Bamforth and Richards provide a detailed explanation of the work of the new natural lawyers within (...) and outside the Catholic Church - the first truly comprehensive explanation available to legal theorists - and criticize Grisez's and Finnis's arguments concerning sexuality and gender. New natural law is, they argue, a theology rather than a secular theory, and one which is unappealing in a modern constitutional democracy. This book will be of interest to legal and political theorists, ethicists, theologians and scholars of religious history. (shrink)

Plato’s Pragmatism offers the first comprehensive defense of a pragmatist reading of Plato. According to Plato, the ultimate rational goal is not to accumulate knowledge and avoid falsehood but rather to live an excellent human life. The book contends that a pragmatic outlook is present throughout the Platonic corpus. The authors argue that the successful pursuit of a good life requires cultivating certain ethical commitments, and that maintaining these commitments often requires violating epistemic norms. In the course of defending the (...) pragmatist interpretation, the authors present a forceful Platonic argument for the conclusion that the value of truth has its limits, and that what matters most are one’s ethical commitments and the courage to live up to them. Their interpretation has far-reaching consequences in that it reshapes how we understand the relationship between Plato’s ethics and epistemology. Plato’s Pragmatism will appeal to scholars and advanced students of Plato and ancient philosophy. It will also be of interest to those working on current controversies in ethics and epistemology.

The Gorgias ends with Socrates telling an eschatological myth that he insists is a rational account and no mere tale. Using this story, Socrates reasserts the central lessons of the previous discussion. However, it isn’t clear how this story can persuade any of the characters in the dialogue. Those (such as Socrates) who already believe the underlying philosophical lessons don’t appear to require the myth, and those (such as Callicles) who reject these teachings are unlikely to be moved by this (...) far-fetched tale. This raises the question of who the myth is told for and what function it is meant to serve. This chapter argues that the myth is aimed, not at Callicles, but Socrates and those who aspire to follow him. There are uncertainties about the philosophical life that are due to the nature of embodiment, as well as reasons to doubt the connection between happiness and virtue. The myth assists with the former by presenting an image that draws a philosopher away from the goods of the body toward the goods of the soul. The story assists with the latter by presenting an image of cosmic justice, thereby securing happiness in proportion to virtue. (shrink)

The purpose of this paper is to (a) show that the received view of the problem of quantificational subordination (QS) is incorrect, and that, consequently, existing solutions do not succeed in explaining the facts, and (b) provide a new account of QS. On the received view of QS within dynamic semantic frameworks, determiners treated as universal quantifiers (henceforth universal determiners) such as all, every, and each behave as barriers to inter-sentential anaphora yet allow anaphoric accessibility in a number of situations. (...) We argue that universal determiners are not intrinsic anaphora barriers and that anaphoric accessibility under them is enabled factors including lexicon information and discourse effects of universal determiners. In support of this viewpoint, we first provide a data survey on the phenomena of QS and its interactions with plurals, rhetorical relations, and adverbial quantification. The results of the survey show that judgments of (naive) native English speakers on the QS examples are quite different from what is claimed in the literature. We argue that the various solutions in the literature, which in general accept that universal determiners are intrinsic anaphora barriers, fail to account for the facts from the survey data. We then describe the approach we adopt, which denies that universal determiners are anaphora barriers and reconstructs their semantics so that information in their scope can be released for anaphora. The constraints on QS noted in the literature we model in Segmented Discourse Representation Theory (SDRT) as conditions on the discourse relations which can hold between subordinated constituents. We show that this approach accounts for the QS data. (shrink)

The rapid developments in technologies -- especially computing and the advent of many 'smart' devices, as well as rapid and perpetual communication via the Internet -- has led to a frequently voiced view which Nicholas Agar describes as 'radical optimism'. Radical optimists claim that accelerating technical progress will soon end poverty, disease, and ignorance, and improve our happiness and well-being. Agar disputes the claim that technological progress will automatically produce great improvements in subjective well-being. He argues that radical optimism (...) 'assigns to technological progress an undeserved pre-eminence among all the goals pursued by our civilization'. Instead, Agar uses the most recent psychological studies about human perceptions of well-being to create a realistic model of the impact technology will have. Although he accepts that technological advance does produce benefits, he insists that these are significantly less than those proposed by the radical optimists, and aspects of such progress can also pose a threat to values such as social justice and our relationship with nature, while problems such as poverty cannot be understood in technological terms. He concludes by arguing that a more realistic assessment of the benefits that technological advance can bring will allow us to better manage its risks in future. (shrink)

In both the Laches (191d-e) and the Laws (1.633c-d, 1.634a-b, and 1. 635d), Plato has his protagonist defend the claim that courage (andreia) is not simply a matter of resisting pain and fear but about overcoming pleasure and desire as well. In this paper, I argue that Plato took the expansive view of courage seriously and that there are several reasons why we should too.

McCarthy et al.’s proposal gains much of its plausibility by relying on a superficial treatment of justice, human dignity, sin, and the common good within the Christian tradition. Upon closer inspection of what these terms mean within the context of Christianity, it becomes clear that despite using the same phrases (e.g., a commitment to “protecting vulnerable populations,” the goal of “promoting justice,” etc.) contemporary secular bioethical goals are often deeply at odds with goals of Christian bioethics. So, while the authors (...) are right that there is room for dialogue (and even agreement) concerning general moral principles, the process of specification and application of these principles will often be heavily influenced by competing ethical traditions. Such divergent influences will often frustrate cooperative ventures between secular and religious bioethical projects. Thus, when put into action, McCarthy et al.’s proposal will—at best—produce a divided kingdom; one that cannot hope to stand. (shrink)

Aristotle’s doctrine of the mean states that each moral virtue stands opposed to two types of vice: one of excess and one of deficiency, respectively. Critics claim that some virtues—like honesty, fair-mindedness, and patience—are counterexamples to Aristotle’s doctrine. Here, I develop a generalizable strategy to defend the doctrine of the mean against such counterexamples. I argue that not only is the doctrine of the mean defensible, but taking it seriously also allows us to gain substantial insight into particular virtues. Failure (...) to take the doctrine seriously, moreover, exposes us to the risk of mistaking certain vices for virtues. (shrink)
