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.

Children’s digital and physical worlds are increasingly entwined as they build and manage meaningful connections online. Central to this is digital empathy and responsible online conduct, i.e., a digital ethics of care. We focus on 10-11-year-old children from a primary school in the UK, exploring how they conceptualise and understand the feelings and behaviours of others. Children interviewed each other in pairs (N=18) following school-based education regarding interviewing skills. Thematic analysis illustrated three themes related to digital empathy and interpretation focused on the discussion of an imaginary experiment of Schrödinger’s cat, as an analogy for digital empathy. This analogy encompassed a finding that in digital environments, consequences of negative behaviours for others are challenging to discern, in terms of effect and affect. The findings have implications for our understanding of digital empathy and the challenge of teaching children responsible conduct online.

In this chapter I summarise Stevenson’s views concerning method in ethics, first tracing their origins in his views about emotive meaning (§2) and the nature of ethical disagreement (§§3-5). Subsequently I outline his views on the nature of reason-giving (§§6-10), and nonrational methods (§11), before addressing criticisms (§12). My negative aim is to dispel any impression that Stevenson reduces ethics to a mere shouting match of emoting, with no space for discussion, collaborative inquiry, reason, open-mindedness, or compromise. My positive aim is to show that Stevenson’s views on method admit of more synthesis than he perhaps realised. In particular, they are bolstered when we pay attention to his views of the function of ethical judgments.

Are moral properties intellectually indispensable, and, if so, what consequences does this have for our understanding of their nature, and of our talk and knowledge of them? Are mathematical objects intellectually indispensable, and, if so, what consequences does this have for our understanding of their nature, and of our talk and knowledge of them? What similarities are there, if any, in the answers to the first two questions? Can comparison of the two cases shed light on which answers are most plausible in either case? This chapter – the introduction to the volume Explanation in Ethics and Mathematics – elucidates these questions and sketches their history.

This paper explores connections between theories of morality and theories of properties. It argues that (1) moral realism is in tension with predicate, class and mereological nominalism; (2) moral non-naturalism is incompatible with standard versions of resemblance nominalism, immanent realism and trope theory; and (3) the standard semantic arguments for property realism do not support moral realism. I also raise doubts about trope-theoretic explanations of moral supervenience and argue against one version of the principle that we should accept theories that maintain neutrality.

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.

In “The Evolutionary Debunking of Quasi-Realism,” Neil Sinclair and James Chamberlain present a novel answer that quasi-realists can pro-vide to a version of the reliability challenge in ethics—which asks for an explanation of why our moral beliefs are generally true—and in so doing, they examine whether evolutionary arguments can debunk quasi-realism. Although reliability challenges differ from EDAs in several respects, there may well be a connection between them. For the explanatory premise of an EDA may state that a particular theory of beliefs of a certain kind does not, or cannot, provide a plausible account of why those beliefs might be generally true, and its epistemic premise may state that, if that is the case, then the beliefs in question have a negative epistemic status or the theory is false inasmuch as, if it were true, it would lead to those beliefs having such a negative epistemic status. The quasi-realist can answer the reli-ability challenge by claiming that, when we form our moral beliefs through a process of well-informed impartial reflection, we form them in response to the non-moral features of things on which depend the moral features they have. Hence, when we form beliefs by means of such a process, we are most likely forming true moral beliefs.

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.

Ethical subjectivists hold that moral judgements are descriptions of our attitudes. Expressivists hold that they are expressions of our attitudes. These views cook with the same ingredients – the natural world, and our reactions to it – and have similar attractions. This Element assesses each of them by considering whether they can accommodate three central features of moral practice: the practicality of moral judgements, the phenomenon of moral disagreement, and the mind-independence of some moral truths. In the process, several different versions of subjectivism are distinguished and key expressivist notions such as 'moral attitudes' and 'expression' are examined. Different meanings of 'subjective' and 'relative' are examined and it is considered whether subjectivism and expressivism make ethics 'subjective' or 'relative' in each of these senses.

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.

Are the circumstances in which moral testimony serves as evidence that our judgement-forming processes are unreliable the same circumstances in which mundane testimony serves as evidence that our mundane judgement-forming processes are unreliable? In answering this question, we distinguish two possible roles for testimony: (i) providing a legitimate basis for a judgement, (ii) providing (‘higher-order’) evidence that a judgement-forming process is unreliable. We explore the possibilities for a view according to which moral testimony does not, in contrast to mundane testimony play role (i), but can play role (ii). We argue that standard motivations for rejecting this hybrid position are unpersuasive but suggest that a more compelling reason might be found in considering the social nature of morality.

At the turn of the twentieth century, G.E. Moore contemptuously dismissed most previous 'ethical systems' for committing the 'Naturalistic Fallacy'. This fallacy – which has been variously understood, but has almost always been seen as something to avoid – was perhaps the greatest structuring force on subsequent ethical theorising. To a large extent, to understand the Fallacy is to understand contemporary ethics. This volume aims to provide that understanding. Its thematic chapters – written by a range of distinguished contributors – introduce the history, text and philosophy behind Moore's charge of fallacy and its supporting 'open question' argument. They detail how the Fallacy influenced multiple traditions in ethics, its connections to supposed dichotomies between 'is'/'ought' and facts/values, and its continuing relevance to our understanding of normativity. Together, the chapters provide a historical and opinionated introduction to contemporary ethics that will be essential for students, teachers and researchers.

This chapter -- the first in the edited collection "The Naturalistic Fallacy" (Cambridge University Press 2019) -- locates the naturalistic fallacy within the context of the other claims Moore defends in Principia Ethica. I explore the notions of “definition” and “analysis” as Moore understood them and set out in detail the multiple interpretations of the fallacy and open question argument. I then take a broad view of the influence of the fallacy on the Century of metaethics that came after Moore, covering topics such as the non-cognitivist appropriation of the open question argument, the mid-Century Humean turn in which the inferential form of the fallacy was dominant, and the fallacy’s role – at the end of the Century – in framing new forms of naturalism. Finally, I argue that these multiple strands of influence demonstrate that, to a large extent, contemporary ethics – and metaethics in particular – can be understood through the framing lens of the naturalistic fallacy.

This paper reflects on fundamental ethical issues concerning designing for behavioural change, in order to raise questions about the factors that should be considered by design practitioners when developing interventions. It draws on existing literature on philosophical ethics, moral psychology and design. It proposes a list of ethical questions and considerations to be made throughout the design process. A case study addressing behavioural changes in antibiotics prescriptions (for Urinary Tract Infections) was carried out to demonstrate how the ethical questions identified are asked and considered. We provide a framework for addressing these issues with the hope that it will help minimise the risk of problematic and unethical intervention design processes.

Nicholas Sturgeon memorably asked: ‘What difference does it make whether moral realism is true?’ His question was prompted by the rise of the metaethical upstart quasi-realism, which urges that an expressivist account of moral discourse is compatible with most, if not all, of its important contours. In his invigorating new book, Cuneo offers a startling new answer to Sturgeon’s question.1 If moral realism were not true, Cuneo argues, we would not be able to speak. But since we evidently can speak, moral realism must be true. So for Cuneo, the Hobbesian view that moral norms are the product of spoken contracts gets things quite the wrong way round: rather, the speech-act of contracting – like all illocutionary speech-acts – is partly the product of...

I argue that evolutionary debunking arguments are dialectically ineffective against a range of plausible positions regarding moral truth. I first distinguish debunking arguments which target the truth of moral judgements from those which target their justification. I take the latter to rest on the premise that such 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 briefly discussing older attempts to bridge this gap, I focus on Joyce’s recent attempt, which rests on the claim that ‘we do not have a believable account of how moral facts could explain the mechanisms and forces which give rise to moral judgements’. I argue that whether or not there is such an account depends on what it is permissible to assume about moral truth in this context. Further, I suggest that it is reasonable to make assumptions about moral truth which allow for the possibility of at least partial moral epistemologies. The residual challenge for the debunker is to show that these assumptions are unreasonable in a way which doesn’t render their debunking argument superfluous.

What is the connection between reasons and motives? According to Reasons Internalism there is a non-trivial conceptual connection between normative reasons and the possibility of rationally accessing relevant motivation. Reasons Internalism is attractive insofar as it captures the thought that reasons are for reasoning with and repulsive insofar as it fails to generate sufficient critical distance between reasons and motives. Rather than directly adjudicate this dispute, I extract from it two generally accepted desiderata on theories of normative reasons and argue that a new theory can satisfy both. The new theory locates part of the meaning of normative reason statements in their role in normative discussion. It generates a view of the connection between reasons and motives that is distinct from Reasons Internalism, yet distinctively in its spirit.

This paper applies the theory of teleosemantics to the issue of moral content. Two versions of teleosemantics are distinguished: input-based and output-based. It is argued that applying either to the case of moral judgements generates the conclusion that such judgements have both descriptive (belief-like) and directive (desire-like) content, intimately entwined. This conclusion directly validates neither descriptivism nor expressivism, but the application of teleosemantics to moral content does leave the descriptivist with explanatory challenges which the expressivist does not face. Since teleosemantics ties content to function, the paper also offers an account of the evolutionary function of moral judgements.

The moral belief problem is that of reconciling expressivism in ethics with both minimalism in the philosophy of language and the syntactic discipline of moral sentences. It is argued that the problem can be solved by distinguishing minimal and robust senses of belief, where a minimal belief is any state of mind expressed by sincere assertoric use of a syntactically disciplined sentence and a robust belief is a minimal belief with some additional property R. Two attempts to specify R are discussed, both based on the thought that beliefs are states that aim at truth. According to the first, robust beliefs are criticisable to the extent that their content fails to match the state of the world. This sense fails to distinguish robust beliefs from minimal beliefs. According to the second, robust beliefs function to have their content match the state of the world. This sense succeeds in distinguishing robust beliefs from minimal beliefs. The conclusion is that the debate concerning the cognitive status of moral convictions needs to address the issue of the function of moral convictions. Evolutionary theorising may be relevant, but will not be decisive, in answering this question.

In this paper I grant the Humean premise that some reasons for action are grounded in the desires of the agents whose reasons they are. I then consider the question of the relation between the reasons and the desires that ground them. According to promotionalism , a desire that p grounds a reason to φ insofar as A’s φing helps promote p . According to motivationalism a desire that p grounds a reason to φ insofar as it explains why, in certain circumstances, A would be motivated to φ. I then give an argument favouring motivationalism, namely that promotionalism entails that agents have reasons to perform physically impossible actions, whereas motivationalism entails that there are no such reasons. Although this is a version of the ‘Too Many Reasons’ objection to promotionalism, I show that existing responses to that problem do not transfer to the case of reasons to perform physically impossible actions. In the penultimate section I consider and reject some objections to motivationalism made by promotionalists. The conclusion is that Humeans about reasons for action should prefer motivationalism
