In this chapter, we argue for three theses: (1) we lack the power to form beliefs at will (i.e., directly); at very least, we lack the power to form at will beliefs of the kind that proponents of doxastic voluntarism have in mind; but (2) we possess a propensity to form beliefs for non-epistemic reasons; and (3) these propensities—once we come to know we have them—entail that we have obligations similar to those we would have were doxastic voluntarism true. Specifically, (...) we will argue that we have obligations to avoid triggering these propensities to form beliefs that are unwarranted or even immoral. (shrink)

A number of concerns have been raised about the possible future use of pharmaceuticals designed to enhance cognitive, affective, and motivational processes, particularly where the aim is to produce morally better decisions or behavior. In this article, we draw attention to what is arguably a more worrying possibility: that pharmaceuticals currently in widespread therapeutic use are already having unintended effects on these processes, and thus on moral decision making and morally significant behavior. We review current evidence on the moral effects (...) of three widely used drugs or drug types: propranolol, selective serotonin reuptake inhibitors, and drugs that effect oxytocin physiology. This evidence suggests that the alterations to moral decision making and behavior caused by these agents may have important and difficult-to-evaluate consequences, at least at the population level. We argue that the moral effects of these and other widely used pharmaceuticals warrant further empirical research and ethical analysis. (shrink)

This paper examines the prospects for a conceptual or functional role theory of moral concepts. It is argued that such an account is well-placed to explain both the irreducibility and practicality of moral concepts. Several versions of conceptual role semantics for moral concepts are distinguished, depending on whether the concept-constitutive conceptual roles are wide or narrow normative or non-normative and purely doxastic or conative. It is argued that the most plausible version of conceptual role semantics for moral concepts involves only (...) ‘narrow’ conceptual roles, where these include connections to motivational, desire-like, states. In the penultimate section it is argued, contrary to what Wedgwood, Enoch and others have claimed, that such an account of moral concepts cannot plausibly be combined with the claim that moral concepts refer to robust properties.

This book defends the Humean Theory of Motivation, according to which desire drives all action and practical reasoning. -/- Desire motivates us to pursue its object. It makes thoughts of its object pleasant. It focuses attention on its object. Its effects are amplified by vivid representations of its object. These aspects of desire explain why motivation usually accompanies moral belief, how intentions shape our plans, how we exercise willpower, what human selves are, how action can express emotion, why we procrastinate, (...) and how we daydream. The Humean Theory also suggests a new account of moral judgment that upholds objectivity while understanding moral concepts in terms of our feelings. (shrink)

It can seem incoherent to fully characterize fundamentality in terms of grounding, given that the fundamental is precisely that which cannot be fully characterized independently. I argue that there is no such incoherence.

The rightness and wrongness of actions fits on a continuous scale. This fits the way we evaluate actions chosen among a diverse range of options, even though English speakers don’t use the words “righter” and “wronger”. I outline and defend a version of scalar consequentialism, according to which rightness is a matter of degree, determined by how good the consequences are. Linguistic resources are available to let us truly describe actions simply as right. Some deontological theories face problems in accounting (...) for degrees of rightness, as they don't invoke continuous parameters among the right-making features of action. (shrink)

Abstract The typical explanation of an event or process which attracts the label ‘conspiracy theory’ is an explanation that conflicts with the account advanced by the relevant epistemic authorities. I argue that both for the layperson and for the intellectual, it is almost never rational to accept such a conspiracy theory. Knowledge is not merely shallowly social, in the manner recognized by social epistemology, it is also constitutively social: many kinds of knowledge only become accessible thanks to the agent's embedding (...) in an environment that includes other epistemic agents. Moreover, advances in knowledge typically require ongoing immersion in this social environment. But the intellectual who embraces a conspiracy theory risks cutting herself off from this environment, and therefore epistemically disabling herself. Embracing a conspiracy theory therefore places at risk the ability to engage in genuine enquiry, including the enquiry needed properly to evaluate the conspiracy theory. (shrink)

If a person is competent to consent to a treatment, is that person necessarily competent to refuse the very same treatment? Risk relativists answer no to this question. If the refusal of a treatment is risky, we may demand a higher level of decision-making capacity to choose this option. The position is known as asymmetry. Risk relativity rests on the possibility of setting variable levels of competence by reference to variable levels of risk. In an excellent 2016 article inJournal of (...) Medical Ethics(JME), Rob Lawlor defends asymmetry of this kind by defending risk relativity, using and developing arguments and approaches found in earlier work such as that of Wilks. He offers what we call the two-scale approach: a scale of risk is to be used to set a standard of competence on a scale of decision-making difficulty. However, can this be done in any rational way? We argue it cannot, and in this sense, and to this extent, risk relativity is a nonsense. (shrink)

It is common in metaethics today to draw a distinction between “naturalist” and “non-naturalist” versions of moral realism, where the former view maintains that moral properties are natural properties, while the latter view maintains that they are non-natural properties instead. The nature of the disagreement here can be understood in different ways, but the most common way is to understand it as a metaphysical disagreement. In particular, the disagreement here is about the reducibility of moral properties, where the “naturalists” maintain (...) that moral properties are in some way reducible to the lower-level natural properties on which they supervene, while the “non-naturalists” maintain that moral properties are sui generis and robustly irreducible. In this paper I present a novel version of realist ethical naturalism—a view that I call Emergentist Ethical Naturalism—that reveals this common way of understanding the distinction between naturalism and non-naturalism to be flawed by combining a commitment to ethical naturalism with a commitment to the sui generis and robustly irreducible nature of moral properties that typically defines non-naturalism. Then, after presenting the theory and addressing a few worries that one might have about it, I show how it offers some novel, emergence-based responses to the various supervenience challenges that plague moral realism and thereby gives the ethical naturalist a robustly non-reductive option for dealing with these challenges.

What is morality? In Practical Expressivism, I argue that morality is a purely natural interpersonal co-ordination device, whereby human beings express their attitudes in order to influence the attitudes and actions of others. -/- The ultimate goal of these expressions is to find acceptable ways of living together. This 'expressivist' model for understanding morality faces well-known challenges concerning 'saving the appearances' of morality, because morality presents itself to us as a practice of objective discovery, not pure expression. -/- This book (...) demonstrates how a properly developed expressivist view can overcome this objection, by showing that even if moral practice is fundamentally expressive, it can still come to possess those features that make it appear objective (features such as talk and thought of moral disagreement, truth and belief, and the applicability of logical notions to moral sentences). The key to this development is to emphasise the unique and intricate practical role that morality plays in our lives. Practical expressivism is also practical in the further sense that it provides repeatable patterns that expressivists can deploy in coming to understand the apparently objective features of morality.

This paper argues that qualia share their physical correlates' locations. The first premise comes from the theory of relativity: If something shares a time with a physical event in all reference frames, it shares that physical event’s location. The second premise is that qualia share times with their correlates in all reference frames. Having qualia and correlates share locations makes relations between them easier to explain, improving both physicalist and dualist theories.

Response to commentary. We are grateful to Crockett and Craigie for their interesting remarks on our paper. We accept Crockett’s claim that there is a need for caution in drawing inferences about patient groups from work on healthy volunteers in the laboratory. However, we believe that the evidence we cited established a strong presumption that many of the patients who are routinely taking a medication, including many people properly prescribed the medication for a medical condition, have morally significant aspects of (...) their cognition and behavior modified in a way that is unintended and may sometimes be unwelcome. Crockett notes that in some cases the effects of long-term drug use may differ, sometimes markedly, from the effects of short-term use. However, if acute use of a drug affects a neural system involved in mediating moral cognition or behavior, this nevertheless provides some evidence that chronic use of the drug may affect that same system and thus have morally significant effects. It is also plausible, in some cases, that an acute moral effect would give rise to a chronic moral effect via cognitive mechanisms. ... (shrink)

Smith scholars have become interested of late in his thoughts on religion, and particularly the question of the degree to which Smith's understanding of religion was indebted to the influence of his close friend Hume. Until now this debate has largely focused on three elements of Smith's religious thought: his personal beliefs, his conception of natural religion, and his treatment of revealed religion. Yet largely unexplored has been one of the most important elements of Smith's thinking about religion: namely his (...) treatment of ‘the natural principles of religion’ in TMS 3.5. What follows aims to reconstruct this treatment and thereby shed light on what Smith might have meant by ‘the natural principles of religion’, and how he understood the relationship of religion and morality more generally – an understanding, it is argued, that significantly differs from Hume's, and reveals Smith to have been a critic of Hume's vision of the relationship of religion to morality, for all their agreements on other fronts.

The self-deceived are usually held to be moral responsible for their state. I argue that this attribution of responsibility makes sense only against the background of the traditional conception of self-deception, a conception that is now widely rejected. In its place, a new conception of self-deception has been articulated, which requires neither intentional action by self-deceived agents, nor that they possess contradictory beliefs. This new conception has neither need nor place for attributions of moral responsibility to the self-deceived in paradigmatic (...) cases. Accordingly, we should take the final step toward abandoning the traditional conception, and drop the automatic attribution of responsibility. Self-deception is simply a kind of mistake, and has no more necessary connection to culpability than have other intellectual errors. (shrink)

This paper presents the Universality Argument that pleasure is goodness. The first premise defines goodness as what should please all. The second premise reduces 'should' to perceptual accuracy. The third premise invokes a universal standard of accuracy: qualitative identity. Since the pleasure of all is accurate solely about pleasure, pleasure is goodness, or universal moral value. The argument proceeds from a moral sense theory that analyzes moral concepts as concerned with what all should hope for, feel guilty about, and admire. (...) This requires rejecting practical anti-empiricism, the view that moral judgment concerns empirically inaccessible norms governing action. (shrink)

In this paper we sketch a new version of aesthetic expressivism. We argue that one advantage of this view is that it explains various putative norms on the formation and revision of aesthetic judgement. We begin by setting out our proposed explananda and a sense in which they can be understood as governing the correct response to putative higher-order evidence in aesthetics. We then summarise some existing discussions of expressivist attempts to explain these norms, and objections raised to them. This (...) will allow us to identify the pitfalls that a good expressivist explanation needs to avoid. Finally, we sketch our preferred version of aesthetic expressivism which includes as a crucial part a hypothesis concerning the distinctive expressive function of aesthetic practice. We then consider how this theory can explain the putative aesthetic norms whilst avoiding the previous objections. (shrink)

There were five kinds of cyber deterrence presented at the workshop on Landscaping strategic cyber deterrence, hosted at the Oxford Internet Institute. They were the well-studied areas of deterrence by ‘punishment’ and ‘denial’, and the novel concepts of deterrence by ‘association’, ‘norms and taboos’, and finally, ‘entanglement’. In the following workshop commentary, I present these five kinds of deterrence and explain them in light of recent developments in the academy and industry. I argue for analytical congruence between all three novel (...) concepts, since they aim to alter the behaviour of actors by adding a social cost in response to breaking norms and conventions. Throughout, I argue that we are beginning to understand how cyber deterrence works, both in theory and practice, and when all concepts are taken together, they become more than the sum of their parts. Finally, I point out an omission of the workshop, where computational modelling and simulation could be added to the landscape of strategic cyber deterrence. (shrink)

Many social trends are conspiring to drive the adoption of greater automation in society, and we will certainly see a greater offloading of human decisionmaking to robots in the future. Many of these decisions are morally salient, including decisions about how benefits and burdens are distributed. Roboticists and ethicists have begun to think carefully about the moral decision making apparatus for machines. Their concerns often center around the plausible claim that robots will lack many of the mental capacities that are (...) indispensable in human moral decision making, such as empathy. To the extent that robots may be robustly artificially intelligent, these concerns subside, but they give way to new worries about creating artificial agents to do our bidding, if those artificial agents have moral standing. We suggest that the question of AI consciousness poses a dilemma. Whether artificially intelligent agents will be conscious or not, we will face serious difficulties in programming them to reliably make moral decisions. (shrink)

This essay examines Friedman's recent approach to the analysis of physical theories. Friedman argues against Quine that the identification of certain principles as ‘constitutive’ is essential to a satisfactory methodological analysis of physics. I explicate Friedman's characterization of a constitutive principle, and I evaluate his account of the constitutive principles that Newtonian and Einsteinian gravitation presuppose for their formulation. I argue that something close to Friedman's thesis is defensible.

It has become an article of faith among historians of logic that the square of opposition diagram is due not to Aristotle, but to Apuleius. I examine three Aristotelian texts and argue that Prior Analytics I.46 contains a square of opposition, making Aristotle the discoverer of the diagram.

I argue that if David Lewis’ modal realism is true, modal realists from different possible worlds can fall in love with each other. I offer a method for uniquely picking out possible people who are in love with us and not with our counterparts. Impossible lovers and trans-world love letters are considered. Anticipating objections, I argue that we can stand in the right kinds of relations to merely possible people to be in love with them and that ending a trans-world (...) relationship to start a relationship with an actual person isn't cruel to one's otherworldly lover.

Ethical reductionism is the best version of naturalistic moral realism. Reductionists regard moral properties as identical to properties appearing in successful scientific theories. Nonreductionists, including many of the Cornell Realists, argue that moral properties instead supervene on scientific properties without identity. I respond to two arguments for nonreductionism. First, nonreductionists argue that the multiple realizability of moral properties defeats reductionism. Multiple realizability can be addressed in ethics by identifying moral properties uniquely or disjunctively with properties of the special sciences. Second, (...) nonreductionists argue that irreducible moral properties explain empirical phenomena, just as irreducible special-science properties do. But since irreducible moral properties don't successfully explain additional regularities, they run the risk of being pseudoscientific properties. Reductionism has all the benefits of nonreductionism, while also being more secure against anti-realist objections because of its ontological simplicity. (shrink)

Theories of self-deception divide into those that hold that the state is characterized by some kind of synchronic tension or conflict between propositional attitudes and those that deny this. Proponents of the latter like Al Mele claim that their theories are more parsimonious, because they do not require us to postulate any psychological mechanisms beyond those which have been independently verified. But if we can show that there are real cases of motivated believing which are characterized by conflicting propositional attitudes, (...) however, the parsimony argument against incongruent mental state accounts is undermined. I argue that anosognosia presents us with a real-life example of motivated belief together with (sub)-doxastic conflict. (shrink)

A central area of current philosophical debate in the foundations of mathematics concerns whether or not there is a single, maximal, universe of set theory. Universists maintain that there is such a universe, while Multiversists argue that there are many universes, no one of which is ontologically privileged. Often forcing constructions that add subsets to models are cited as evidence in favour of the latter. This paper informs this debate by analysing ways the Universist might interpret this discourse that seems (...) to necessitate the addition of subsets to V. We argue that despite the prima facie incoherence of such talk for the Universist, she nonetheless has reason to try and provide interpretation of this discourse. We analyse extant interpretations of such talk, and analyse various tradeoffs in naturality that might be made. We conclude that the Universist has promising options for interpreting different forcing constructions. (shrink)

Addiction remains a challenging disorder, both to treat and to conceptualise. While the temporal dimension of addiction has been noted before, here the aim is to ground this understanding in a coherent phenomenological-neuroscience framework. Addiction is partly understood as drawing the subject into a predominantly “now” orientated existence, with the future closed or experienced as extremely distant. Another feature of this temporal structuring is that past experiences, which are crucial in advancing intentionally forward, are experienced in addiction as a void. (...) This has implications for the generation of meaning and forming of self, amongst others. While there are areas of the brain that regulate temporal processing, there is no single location. Recent addiction research has implicated the insula and in turn this area is implicated in temporal and interoceptive awareness. Similarly these areas of disruption may affect self processes. Disruption of interoception and thus of self, may help explain why addiction is complex and involves multiple aspects of subjectivity. (shrink)

This chapter argues that evolutionary debunking arguments are dialectically ineffective. Such arguments rely on the premise that moral judgements can be given evolutionary explanations which do not invoke their truth. The challenge for the debunker is to bridge the gap between this premise and the conclusion that moral judgements are unjustified. After discussing older attempts to bridge this gap, this chapter focuses on Joyce’s recent attempt, which claims that ‘we do not have a believable account of how moral facts could (...) explain the mechanisms…which give rise to moral judgements’. It argues that whether there is such an account depends on what it is permissible to assume about moral truth and that it is reasonable to make assumptions which allow for the possibility of at least partial moral epistemologies. The challenge for the debunker is to show that these assumptions are unreasonable in a way which does not render their debunking argument superfluous. (shrink)

I present a novel objection to fine-tuning arguments for God's existence. On any values of the physical constants, the psychophysical laws could be set to permit intelligent and happy beings, so the specific values of the physical constants in our world provide little evidence for God's existence. For example, even if the physical constants didn't allow carbon or any atoms larger than hydrogen, the psychophysical laws could be set so that charge is sufficient to realize romantic desire. Then every hydrogen (...) atom would be a proton and electron in love. (shrink)

What is a language? What do scientific grammars tell us about the structure of individual languages and human language in general? What kind of science is linguistics? These and other questions are the subject of Ryan M. Nefdt's Language, Science, and Structure. -/- Linguistics presents a unique and challenging subject matter for the philosophy of science. As a special science, its formalisation and naturalisation inspired what many consider to be a scientific revolution in the study of mind and language. (...) Yet radical internal theory change, multiple competing frameworks, and issues of modelling and realism have largely gone unaddressed in the field. Nefdt develops a structural realist perspective on the philosophy of linguistics which aims to confront the aforementioned topics in new ways while expanding the outlook toward new scientific connections and novel philosophical insights. On this view, languages are real patterns which emerge from complex biological systems. Nefdt's exploration of this novel view will be especially valuable to those working in formal and computational linguistics, cognitive science, and the philosophies of science, mathematics, and language.

In the contemporary philosophy of set theory, discussion of new axioms that purport to resolve independence necessitates an explanation of how they come to be justified. Ordinarily, justification is divided into two broad kinds: intrinsic justification relates to how `intuitively plausible' an axiom is, whereas extrinsic justification supports an axiom by identifying certain `desirable' consequences. This paper puts pressure on how this distinction is formulated and construed. In particular, we argue that the distinction as often presented is neither well-demarcated nor (...) sufficiently precise. Instead, we suggest that the process of justification in set theory should not be thought of as neatly divisible in this way, but should rather be understood as a conceptually indivisible notion linked to the goal of explanation.

Proponents of evolutionary psychology take the existence of humanuniversals to constitute decisive evidence in favor of their view. Ifthe same social norms are found in culture after culture, we have goodreason to believe that they are innate, they argue. In this paper Ipropose an alternative explanation for the existence of humanuniversals, which does not depend on them being the product of inbuiltpsychological adaptations. Following the work of Brian Skyrms, I suggestthat if a particular convention possesses even a very small advantageover (...) competitors, whatever the reason for that advantage, we shouldexpect it to become the norm almost everywhere. Tiny advantages aretranslated into very large basins of attraction, in the language of gametheory. If this is so, universal norms are not evidence for innatepsychological adaptations at all. Having shown that the existence ofuniversals is consistent with the so-called Standard Social ScienceModel, I turn to a consideration of the evidence, to show that thisstyle of explanation is preferable to the evolutionary explanation, atleast with regard to patterns of gender inequality.

The independence phenomenon in set theory, while pervasive, can be partially addressed through the use of large cardinal axioms. A commonly assumed idea is that large cardinal axioms are species of maximality principles. In this paper I question this claim. I show that there is a kind of maximality (namely absoluteness) on which large cardinal axioms come out as restrictive relative to a formal notion of restrictiveness. Within this framework, I argue that large cardinal axioms can still play many of (...) their usual foundational roles. (shrink)

Zero provides a challenge for philosophers of mathematics with realist inclinations. On the one hand it is a bona fide cardinal number, yet on the other it is linked to ideas of nothingness and non-being. This paper provides an analysis of the epistemology and metaphysics of zero.

Let's suppose you think that there are no uncountable sets. Have you adopted a restrictive position? It is certainly tempting to say yes---you've prohibited the existence of certain kinds of large set. This paper argues that this intuition can be challenged. Instead, I argue that there are some considerations based on a formal notion of restrictiveness which suggest that it is restrictive to hold that there are uncountable sets.

A growth in consumer and media ethical consciousness has resulted in the need for organizations to ensure that members understand, share and project an approved and unified set of ethics. Thus understanding which variables are related to sharing and variation of ethical reasoning and moral intent, and the relative strength of these variables is critical. While past research has examined individual (attitudes, values, etc.), social (peers, significant others, etc.) and organizational (codes of conduct, senior management, etc.) variables, it has focused (...) on their influence on the individual – and not on their role in relation to patterns of group sharing and variation in an organization. Introduced as a new methodology to study ethics, microcultural analysis stipulates that to explain patterns of sharing and variation, one must understand how individual, social and organizational variables influence sharing and variation. Key hypotheses predict that managers who share in individual, social or organizational determinants will be more likely to share in ethical reasoning and moral intent. Qualitative and quantitative research supports the key hypotheses, finding social ties, personal moral intensity, Machiavellianism, locus of control and codes of ethics as significant determinants. Individuals who share in these determinants are more likely to share in ethical reasoning and moral intent. Additionally, regression analysis reveals social ties and personal moral intensity to be the strongest determinants. Based on these results, managerial recommendations focus on a holistic approach, manipulating these three determinants to cultivate a unified code of ethics within an organization. (shrink)

The paper is a defense of the moral methodology of John Rawls against criticisms by R.M. Hare and Peter Singer. Rawls is accused of intuitionism and subjectivism by Hare and of subjectivism and relativism by Singer, I argue that Rawls does not rely on intuitions as such, but on judgments on which there is a consensus. This does not commit Rawls to subjectivism for what is required for objectivity in ethics as in science is simply a rational justification procedure for (...) principles, which Rawls provides. Moreover, an appeal to a moral consensus at some point is inescapable. Finally, concerning the charge of relativism, I point out that Rawls includes in his justification procedure only those judgments on which there is a consensus among competent judges. Though there is the possibility that conflicting sets of judgments may be equally valid for different societies in the unlikely case that there is nothing invariant in the judgments of competent judges, this is a relativism we can accept.

Often philosophers, logicians, and mathematicians employ a notion of intended structure when talking about a branch of mathematics. In addition, we know that there are foundational mathematical theories that can find representatives for the objects of informal mathematics. In this paper, we examine how faithfully foundational theories can represent intended structures, and show that this question is closely linked to the decidability of the theory of the intended structure. We argue that this sheds light on the trade-off between expressive power (...) and meta-theoretic properties when comparing first-order and second-order logic. (shrink)
