The claim that ordinary ethical discourse is typically true and that ethical facts are typically knowable seems in tension with the claim that ordinary ethical discourse is about features of reality friendly to a scientific worldview. Cornell Realism attempts to dispel this tension by claiming that ordinary ethical discourse is, in fact, discourse about the same kinds of things that scientific discourse is about: natural properties. We offer two novel arguments in reply. First, we identify a key assumption that we (...) find unlikely to be true. Second, we identify two features of typical natural properties that ethical properties lack. We conclude that Cornell Realism falls short of dispelling the tension between ethical conservativism and ethical naturalism. (shrink)

This paper is about how moral disagreement matters for metaethics. It has four parts. In the first part I argue that moral facts are subject to a certain epistemic accessibility requirement. Namely, moral facts must be accessible to some possible agent. In the second part I show that because this accessibility requirement on moral facts holds, there is a route from facts about the moral disagreements of agents in idealized conditions to conclusions about what moral facts there are. In the (...) third part I build on this route to show that (*) if there is significant moral disagreement in idealized conditions, then our understanding of morality is fatally flawed and we should accept relativism over non-naturalism and quasi-realism. So, if, like many, you think that there would be significant moral disagreement in idealized conditions, you should hold that our understanding of morality is fatally flawed and reject non-naturalism and quasi-realism. In the fourth part of this paper I show that (*) undermines the plausibility of non-naturalism, quasi-realism, and the view that our understanding of morality is not fatally flawed even if we do not have sufficient reason to believe that there would be significant moral disagreement in idealized conditions.

I consider whether evolutionary explanations can debunk our moral beliefs. Most contemporary discussion in this area is centred on the question of whether debunking implications follow from our ability to explain elements of human morality in terms of natural selection, given that there has been no selection for true moral beliefs. By considering the most prominent arguments in the literature today, I offer reasons to think that debunking arguments of this kind fail. However, I argue that a successful evolutionary debunking (...) argument can be constructed by appeal to the suggestion that our moral outlook reflects arbitrary contingencies of our phylogeny, much as the horizontal orientation of the whale’s tail reflects its descent from terrestrial quadrupeds. An introductory chapter unpacks the question of whether evolutionary explanations can debunk our moral beliefs, offers a brief historical guide to the philosophical discussion surrounding it, and explains what I mean to contribute to this discussion. Thereafter follow six chapters and a conclusion. The six chapters are divided into three pairs. The first two chapters consider what contemporary scientific evidence can tell us about the evolutionary origins of morality and, in particular, to what extent the evidence speaks in favour of the claims on which debunking arguments rely. The next two chapters offer a critique of popular debunking arguments that are centred on the irrelevance of moral facts in natural selection explanations. The final chapters develop a novel argument for the claim that evolutionary explanations can undermine our moral beliefs insofar as they show that our moral outlook reflects arbitrary contingencies of our phylogeny. A conclusion summarizes my argument and sets out the key questions that arise in its wake. (shrink)

This chapter has two sections, each focusing on a distinct way in which ethical disagreement and variations in ethical judgment matter for theories of ethical thought and talk. In the first section, we look at how the variation poses problems for both cognitivist and non-cognitivist ways of specifying the nature of ethical judgments. In the second, we look at how disagreement phenomena have been taken to undermine cognitivist accounts, but also at how the seeming variation in cognitive and non-cognitive contents (...) between parties of deep ethical disagreement challenges both cognitivist and non-cognitivist accounts of disagreement itself.

Many philosophers accept a response constraint on normative reasons: that p is a reason for you to φ only if you are able to φ for the reason that p. This constraint offers a natural way to cash out the familiar and intuitive thought that reasons must be able to guide us, and has been put to work as a premise in a range of influential arguments in ethics and epistemology. However, the constraint requires interpretation and faces putative counter-examples due (...) to Julia Markovits, Mark Schroeder, and others. This paper develops and motivates an interpretation of the response constraint that avoids the putative counter-examples. (shrink)

Despite the widespread use of the notion of moral intuition, its psychological features remain a matter of debate and it is unclear why the capacity to experience moral intuitions evolved in humans. We first survey standard accounts of moral intuition, pointing out their interesting and problematic aspects. Drawing lessons from this analysis, we propose a novel account of moral intuitions which captures their phenomenological, mechanistic, and evolutionary features. Moral intuitions are composed of two elements: an evaluative mental state and a (...) feeling of rightness (FOR). We illustrate the phenomenology of the FOR with examples of non-moral and moral cases, and provide a biological and mechanistic account: the emergence of human reasoning capacities created a need for the co-evolution of a psychological system producing the feeling of rightness (the FORs). This system is triggered when we experience conflicting evaluations. The FORs renders evaluations resulting from rational deliberation less compelling than the evaluations produced by simple evolved systems. It thus facilitates optimal decision-making, preventing excessive interference by rational deliberation. Our account sheds light on why moral intuitions are so frequently experienced and why they are so compelling and resistant to argument. In addition, the account fuels interesting speculations about common metaethical intuitions. (shrink)

Experimental philosophy is a new interdisciplinary field that uses methods normally associated with psychology to investigate questions normally associated with philosophy. The present review focuses on research in experimental philosophy on four central questions. First, why is it that people's moral judgments appear to influence their intuitions about seemingly nonmoral questions? Second, do people think that moral questions have objective answers, or do they see morality as fundamentally relative? Third, do people believe in free will, and do they see free (...) will as compatible with determinism? Fourth, how do people determine whether an entity is conscious? (shrink)

Normative realists tend to consider evolutionary debunking arguments as posing epistemological challenges to their view. By understanding Sharon Street’s ‘Darwinian dilemma’ argument in this way, they have overlooked and left unanswered her unique scientific challenge to normative realism. This paper counters Street’s scientific challenge and shows that normative realism is compatible with an evolutionary view of human evaluative judgment. After presenting several problems that her adaptive link account of evaluative judgments faces, I outline and defend an evolutionary byproduct perspective on (...) evaluative judgment. I then argue that a consideration of levels of analysis in biological–behavioral explanation suggests that the realist who adopts the byproduct perspective I outline is not at a prima facie disadvantage to the normative anti-realist on grounds of parsimony. This perspective, I suggest, can enable normative realists to answer evolutionary challenges to their view. (shrink)

According to Bernard Williams, if it is true that A has a normative reason to Φ then it must be possible that A should Φ for that reason. This claim is important both because it restricts the range of reasons which agents can have and because it has been used as a premise in an argument for so-called ‘internalist’ theories of reasons. In this paper I rebut an apparent counterexamples to Williams’ claim: Schroeder’s example of Nate. I argue that this (...) counterexample fails since it underestimates the range of cases where agents can act for their normative reasons. Moreover, I argue that a key motivation behind Williams’ claim is compatible with this ‘expansive’ account of what it is to act for a normative reason. (Published with Open Access.). (shrink)

There are at least two basic normative notions: rationality and reasons. The dominant normative account of reasons nowadays, which I call primitive pluralism about reasons, holds that some reasons are normatively basic and there is no underlying normative explanation of them in terms of other normative notions. Kantian constructivism about reasons, understood as a normative rather than a metaethical view, holds that rationality is the primitive normative notion that picks out which non-normative facts are reasons for what and explains why (...) those normative relations hold. By supposing that there is a plurality of primitive reasons, I argue that primitive pluralism about reasons lacks sufficient normative unity and structure. But Kantian constructivism about reasons faces a dilemma of its own: Either a conception of rationality is thick enough to capture the reasons of commonsense, in which case it cannot play the explanatory role assigned to it, or a conception of rationality is genuinely explanatory, in which case it is too thin to generate the reasons we recognize in commonsense. The aim of this paper is to suggest that if Kantian constructivism about reasons were built on a substantive, rather than merely formal, conception of rationality then it would stand a better chance at unifying the particular reasons we would endorse on due reflection. The groundwork I lay in this paper, I explain, is an essential first step in the larger project of developing a version of Kantian constructivism about reasons that might eventually explain all reasons in terms of rationality.

I have recently argued that if the causal theory of reference is true, then, on pain of absurdity, no normative ethical theory is true. In this journal, Michael Byron has objected to my reductio by appealing to Frank Jackson’s moral reductionism. The present essay defends reductio while also casting doubt upon Jackson’s moral reductionism.

This paper is about the relationship between two widely accepted and apparently conflicting claims about how we should understand the notion of ‘reason giving’ invoked in theorising about reasons for action. According to the first claim, reasons are given by facts about the situation of agents. According to the second claim, reasons are given by ends. I argue that the apparent conflict between these two claims is less deep than is generally recognised.

It is through our actions that we affect the way the world goes. Whenever we face a choice of what to do, we also face a choice of which of various possible worlds to actualize. Moreover, whenever we act intentionally, we act with the aim of making the world go a certain way. It is only natural, then, to suppose that an agent's reasons for action are a function of her reasons for preferring some of these possible worlds to others, (...) such that what she has most reason to do is to bring about the possible world which, of all those available to her, is the one that she has most reason to want to obtain. This is what is known as the `teleological conception of practical reasons'. Whether this is the correct conception of practical reasons is important not only in its own right, but also in virtue of its potential implications for what sort of moral theory we should accept. Below, I argue that the teleological conception is indeed the correct conception of practical reasons. (shrink)

There has been a great deal of discussion in the recent philosophical literature of the relationship between the minimalist theory of truth and the expressivist metaethical theory. One group of philosophers contends that minimalism and expressivism are compatible, the other group contends that such theories are incompatible. Following Simon Blackburn (manuscript), I will call the former position ‘compatibilism’ and the latter position ‘incompatiblism.’ Even those compatibilist philosophers who hold that there is no conflict or tension between these two theories—minimalism and (...) expressivism—typically think that some revision of minimalism is required to accommodate expressivism. The claim that there is such an incompatibility, I will argue, is based on a misunderstanding of the historical roots of expressivism, the motivations behind the expressivist theory, and the essential commitments of expressivism. I will present an account of the expressivist theory that is clearly consistent with minimalism. (shrink)

Motivational judgement internalists hold that there is a necessary connection between moral judgments and motivation. There is, though, an important lack of clarity in the literature about the types of moral evaluation the theory is supposed to cover. It is rarely made clear whether the theory is intended to cover all moral judgements or whether the claim covers only a subset of such judgements. In this paper I will investigate which moral judgements internalists should hold their theory to apply to. (...) I will argue that the possibility of the supererogation amoralist, someone who makes genuine supererogation judgements but remains unmotivated by them, makes it implausible to be an internalist about moral goodness. As a result, internalists should restrict their claim to moral requirement judgements. I will then argue that this creates an explanatory burden for Internalism. In order for their view to be plausible they must explain why some moral judgements and not others are necessarily connected to motivation. (shrink)

Moral Relativism can be considered an attractive alternative to realism because relativists can make good sense of cultural and societal disagreements by seeing them as faultless. However, we can show that this advantage is made possible by systematically disagreeing with moral phenomenology. Relativists make a substantial distinction between intercultural and intracultural discourses which turns out to be incoherent. This can be shown by making use of Crispin Wright’s notion of Cognitive Command.

In this paper the 'moral fetishism' argument originally presented by Michael Smith against moral judgment externalism is defended. I argue that only the internalist views on the relation of moral judgment and motivation can combine two attractive theses: first, that the morally admirable are motivated to act on the reasons they take to ground actions' being right, and second, that their virtuousness need not be diminished by their acting on their thinking something right. Lastly, some possibilities are envisaged for internalists (...) in light of a worry to the effect that the argument, if successful, undermines the internalist theories, too. (shrink)

In this chapter I critically discuss the dismissal of the philosophical significance of facts about human evolution and historical development in the work of W. D Ross. I address Ross’s views about the philosophical significance of the emerging human sciences of his time in two of his main works, namely The Right and the Good and The Foundations of Ethics. I argue that the debate between Ross and his chosen interlocutors (Herbert Spencer, Emile Durkheim and Lucien Levy-Bruhl) shows striking similarities (...) with parallel debates in contemporary moral philosophy. (shrink)

This paper is a survey of the supervenience challenge to non-naturalist moral realism. I formulate a version of the challenge, consider the most promising non-naturalist replies to it, and suggest that no fully effective reply has yet been given.

The effects of anthropogenic climate change may be devastating. Nevertheless, most people do not seem to be seriously concerned. We consume as much as we always did, drive as much as we always did, eat as much meat as we always did. What can we do to overcome this collective apathy? In order to be able to develop effective measures, we must first get clear about the causes of climate change inaction. In this paper I ask whether moral nihilism is (...) a significant cause of climate change inaction. The answer to this question depends mainly on the extent to which being a moral nihilist reduces one's likelihood of taking action against climate change. At first sight, the extent seems to be considerable. I argue, however, that this assumption is false. Only slightly more non-nihilists than nihilists are led to climate-friendly actions by moral considerations. And in absolute terms, morality plays such a minor role in leading people to act that the difference is barely noticeable. (shrink)

Sharon Street argues that realism about epistemic normativity is false. Realists believe there are truths about epistemic reasons that hold independently of the agent’s attitudes. Street argues by dilemma. Either the realist accepts a certain account of the nature of belief, or she does not. If she does, then she cannot consistently accept realism. If she does not, then she has no scientifically credible explanation of the fact that our epistemic behaviours or beliefs about epistemic reasons align with independent normative (...) truths. I argue that neither horn is very sharp for realists about epistemic normativity. (shrink)

This article is about the implications of a conciliatory view about the epistemology of peer disagreement for our moral beliefs. Many have endorsed a conciliatory view about the epistemology of peer disagreement according to which if we find ourselves in a disagreement about some matter with another whom we should judge to be our epistemic peer on that matter, we must revise our judgment about that matter. This article focuses on three issues about the implications of conciliationism for our moral (...) beliefs. The first is whether there is an asymmetry between the implications of conciliationism for the epistemic status of our moral beliefs and the implications of conciliationism for the epistemic status of our non-moral beliefs; for instance, some have argued that conciliationism leads to epistemological moral skepticism but not to epistemological nonmoral skepticism. The second is what the implications of conciliationism are for the epistemic status of particular moral beliefs. The third is whether conciliationism's impact on the epistemic status of our moral beliefs has practical implications. (shrink)

Are values objective or subjective? To clarify this question we start with an overview of the main concepts and debates in the philosophy of values. We then discuss the arguments for and against value realism, the thesis that there are objective evaluative facts. By contrast with value anti-realism, which is generally associated with sentimentalism, according to which evaluative judgements are grounded in sentiments, value realism is commonly coupled with rationalism. Against this common view, we argue that value realism can be (...) combined with sentimentalism, and we suggest that a plausible account, which we call ‘sentimental realism’, and according to which evaluative judgements are closely related to emotions, can be developped. (shrink)

Despite the efforts of meta-ethical expressivists to rebut such worries, one objection raised over and over again against expressivism is that, if the theory is true, matters of morality must be mind-dependent in some objectionable way. This paper develops an argument which not only shows that this is and cannot be the case, but also – and perhaps more importantly – offers a diagnosis why philosophers are nevertheless so often led to think otherwise.

Analytic reductivism in metaethics has long been out of philosophical vogue. In Confusion of Tongues: A Theory of Normativity (2014), Stephen Finlay tries to resuscitate it by developing an analytic metaethical reductive naturalistic semantics for ‘good.’ He argues that an end-relational semantics is the simplest account that can explain all of the data concerning the term, and hence the most plausible theory of it. I argue that there are several assumptions that a reductive naturalist would need to make about contextual (...) parameter completion to derive reductive naturalism from an end-relational semantics—assumptions that nonnaturalists might forcefully resist. I also argue for the claim that an end-relational semantics could provide surprising resources for nonnaturalists to address semantic worries about their views—the upshot of which paints the way for a new and sophisticated nonnaturalism about the semantics of moral discourse. Nonnaturalists have long suspected that they need not worry about semantics and this paper lends support to that suspicion. (shrink)

In this paper, I argue that an externalist theory of thought content provides the means to resolve two debates in moral philosophy. The first—that between judgement internalism and judgement externalism—concerns the question of whether there is a conceptual connection between moral judgement and motivation. The second—that between reasons internalism and reasons externalism—concerns the relationship between moral reasons and an agent's subjective motivational set. The resolutions essentially stem from the externalist claim that concepts can be grasped partially, and a new moral (...) theory, which I call ‘moral externalism’, emerges. (shrink)

This chapter offers an introduction to naturalist views in contemporary metaethics. Such views attempt to find a place for normative properties (such as goodness and rightness) in the concrete physical world as it is understood by both science and common sense. The chapter begins by introducing simple naturalist conceptual analyses of normative terms. It then explains how these analyses were rejected in the beginning of the 20th Century due to G.E. Moore’s influential Open Question Argument. After this, the chapter considers (...) what good general reasons there are for defending naturalism in metaethics. The bulk of the chapter will then survey new semantic and metaphysical forms of naturalism which in different ways attempt to address Moore’s objection to naturalism. These more recent versions of naturalism—using new resources from philosophy of language, philosophy of mind, metaphysics, philosophy of science and epistemology—attempt to explain why the Open Question Argument fails.

Judgment internalism about evaluative judgments is the view that there is a necessary internal connection between evaluative judgments and motivation understood as desires. The debate about judgment internalism has reached a standoff some time ago. In this paper, I outline a new argument for judgment internalism. This argument does not rely on intuitions about cases, but rather it has the form of an inference to the best explanation. I argue that the best philosophical explanations of how we know what we (...) desire require that judgment internalism is true, which gives us a good reason to believe that judgment internalism is true.

Jonas Olson presents a critical survey of moral error theory, the view that there are no moral facts and so all moral claims are false. Part I explores the historical context of the debate; Part II assesses J. L. Mackie's famous arguments; Part III defends error theory against challenges and considers its implications for our moral thinking.

Moral skeptics maintain that we do not have moral knowledge. Traditionally they haven’t argued via skeptical hypotheses like those provided by perceptual skeptics about the external world, such as Descartes’ deceiving demon. But some believe this can be done by appealing to hypotheses like moral nihilism. Moreover, some claim that skeptical hypotheses have special force in the moral case. But I argue that skeptics have failed to specify an adequate skeptical scenario, which reveals a general lesson: such arguments are not (...) a promising avenue for moral skeptics to take. They’re ultimately weaker when applied to morality compared to perception. (shrink)

According to rationalists about moral knowledge, some moral truths are knowable a priori. Rationalists often defend their position by claiming that some moral propositions are self-evidently true. Copp 2007 has recently challenged this rationalist strategy. Copp argues that even if some moral propositions are self-evident, this is not enough to secure rationalism about moral knowledge, since it turns out that such self-evident propositions are only knowable a posteriori. This paper considers the merits of Copp’s challenge. After clarifying the rationalists’ appeal (...) to self-evidence, I show why this rationalist strategy survives Copp’s challenges to it. (shrink)

In Kitcher’s ‘pragmatic naturalism’ moral evolution consists in pragmatically motivated moral changes in response to practical difficulties in social life. No moral truths or facts exist that could serve as an ‘external’ measure for moral progress. We propose a psychologically realistic conception of moral objectivity consistent with this pragmatic naturalism yet alive to the familiar sense that moral progress has an objective basis that transcends convention and consensus in moral opinion, even when these are products of serious, extended and collaborative (...) reflection.

Distributive egalitarians believe that distributive justice is to be explained by the idea of distributive equality (DE) and that DE is of intrinsic value. The socio-relational critique argues that distributive egalitarianism does not account for the “true” value of equality, which rather lies in the idea of “equality as a substantive social value” (ESV). This paper examines the socio-relational critique and argues that it fails because – contrary to what the critique presupposes –, first, ESV is not conceptually distinct from (...) DE, and second, the idea of ESV cannot serve as a “foundation” or “root” of distributive egalitarianism. (shrink)

Does evolutionary theory have the potential to undermine morality? In his book The Evolution of Morality, Richard Joyce (2006) argues for a positive answer. He contends that an evolutionary account of morality would undermine moral judgements and lend support to moral scepticism. I offer a critique of Joyce’s argument. As it turns out, his case can be read in two different ways. It could be construed as an argument to establish a general scepticism about the justification of moral judgements. Or (...) it could be read as an argument that targets only a particular meta-ethical position, namely moral realism. My claim is that it fails on both interpretations. There is no reason to believe that evolutionary considerations undermine morality. (shrink)

An encyclopedia entry on the issue of whether morality is reducible -- that is, whether moral facts are identical to facts that can be expressed in non-moral terms.

This paper concerns non-causal normative explanations such as ‘This act is wrong because/in virtue of__’. The familiar intuition that normative facts aren't brute or ungrounded but anchored in non- normative facts seems to be in tension with the equally familiar idea that no normative fact can be fully explained in purely non- normative terms. I ask whether the tension could be resolved by treating the explanatory relation in normative explanations as the sort of ‘grounding’ relation that receives extensive discussion in (...) recent metaphysics. I argue that this would help only under controversial assumptions about the nature of normative facts, and perhaps not even then. I won't try to resolve the tension, but draw a distinction between two different sorts of normative explanations which helps to identify constraints on a resolution. One distinctive constraint on normative explanations in particular might be that they should be able to play a role in normative justification. (shrink)

This article analyzes the source of Confucian universal morality and human dignity from the perspective of the classic saying, ?what follows the dao is good, and what dao forms is nature? (jishan chengxing) found in the Great Commentaries of the Book of Changes. From a Classical Confucian perspective, human nature is generated by the natural dao of tian, so human dignity and morality also emerge from the natural dao of tian. This article discusses the relationship between the Confucian dao of (...) tian and the moral notion of human rights which ensues from the historical tradition of Chinese exegesis on this subject. Specifically, the authors reconstruct a naturalist version of Confucian morality which inherently motivates the beneficial outcomes generally associated with the modern Western conception of human rights. The authors argue that such a framework, which would draw upon Confucian ?natural goodness within human nature? differs significantly from the more commonly accepted Mencian version of human morality dependent upon the premise that ?human nature is good?. This intra-mural differentiation within Chinese philosophy can be helpful in structuring dialogue with various Western theories of human rights. (shrink)

Reviews work on moral judgment motivational internalism from the last two decades.

Jonathan Dancy thinks that there are irreducibly normative properties. Frank Jackson has given a well-known argument against this view, and I have elsewhere defended this argument against many objections, including one made by Dancy. But Dancy remains unconvinced. In this chapter, I hope to convince him.

Regan appeals to the benefit of the doubt as a reason to include some animals within the scope of his arguments about the rights of animals. I think the informal appeal to the benefit of the doubt can be fleshed out and made more compelling. What I shall do differs from his project, however. It is narrower in scope, because I shall focus on a single issue, the dietary use of animals. On another dimension, though, I aim to do more. (...) Regan thinks that it is “not unreasonable” to extend the benefit of the doubt, and that it is better to do so. I shall be arguing that it is unreasonable not to do so. (shrink)

Our beliefs about which actions we ought to perform clearly have an effect on what we do. But so-called “Humean” theories—holding that all motivation has its source in desire—insist on connecting such beliefs with an antecedent motive. Rationalists, on the other hand, allow normative beliefs a more independent role. I argue in favor of the rationalist view in two stages. First, I show that the Humean theory rules out some of the ways we ordinarily explain actions. This shifts the burden (...) of proof onto Humeans to motivate their more restrictive, revisionary account. Second, I show that they are unlikely to discharge this burden because the key arguments in favor of the Humean theory fail. I focus on some of the most potent and most recent lines of argument, which appeal to either parsimony, the teleological nature of motivation, or the structure of practical reasoning. (shrink)

Much recent work in meta-ethics and ethical theory has drawn extensively on claims about moral psychology. The goal of this paper is to provide a broad overview of some of these claims and the implications that certain philosophers are taking them to have for the plausibility of moral relativism.

In this paper, I hope to provide an account of the conditions of moral realism whereby there are still significant metaphysical commitments made by the realist which set the view apart as a distinct position in the contemporary meta-ethical landscape. In order to do so, I will be appealing to a general account of what it is for realism to be true in any domain of experience, whether it be realism about universals, realism about unobservable scientific entities, realism about artifacts, (...) and so forth.

The Euthyphro Dilemma is named after a particular exchange between Socrates and Euthyphro in Plato‟s dialogue Euthyphro. In a famous passage, Socrates asks, “Is the pious loved by the gods because it is pious, or is it pious because it is loved by the gods?” (Plato 1981: 10a), and proceeds to advance arguments which clearly favor the first of these two options (see PLATO). The primary interest in the Euthyphro Dilemma over the years, however, has primarily concerned the relationship between (...) God and morality in the monotheistic religious tradition, where God is taken to be omnipotent, omniscient, and omnibenevolent, having created the universe initially and still actively involved in it today. But as we will see at the end of this entry, there has also been a recent surge of interest in a version of the Dilemma which applies to so-called response-dependent accounts of normative properties in meta-ethics.

It has often been suggested that people's ordinary understanding of morality involves a belief in objective moral truths and a rejection of moral relativism. The results of six studies call this claim into question. Participants did offer apparently objectivist moral intuitions when considering individuals from their own culture, but they offered increasingly relativist intuitions considering individuals from increasingly different cultures or ways of life. The authors hypothesize that people do not have a fixed commitment to moral objectivism but instead tend (...) to adopt different views depending on the degree to which they consider radically different perspectives on moral questions.

According to some recent arguments, if our moral beliefs are products of natural selection, then we do not have moral knowledge. In defense of this inference, its proponents argue that natural selection is a process that fails to track moral facts. In this paper, I argue that our having moral knowledge is consistent with, the hypothesis that our moral beliefs are products of natural selection, and the claim that natural selection fails to track moral facts. I also argue that natural (...) selection is a process that could track moral facts, albeit imperfectly. I do not argue that we do have moral knowledge. I argue instead that Darwinian considerations provide us with no reason to doubt that we do, and with some reasons to suppose that we might. (shrink)

More and more people seem to think that constructivism - in political philosophy, in moral philosophy, and perhaps in practical reasoning most generally - is the way to go. And yet it is surprisingly hard to even characterize the view. In this paper, I go to some lengths trying to capture the essence of a constructivist position - mostly in the realm of practical reason - and to pinpoint its theoretical attractions. I then give some reason to suspect that there (...) cannot be a coherent constructivist view about practical reason as a whole, at least not if it is to be interestingly constructivist, in a sense I make reasonably precise.

The main aim of this thesis is to defend moral realism. In chapter 1, I argue that moral realism is best understood as the view that moral sentences have truth-value, there are moral properties that make some moral sentences true, and moral properties are not reducible to non- moral properties. Realism is contrasted with non-cognitivism, error-theory and reductionism, which, in brief, deny, and, respectively. In the introductory chapter, it is also argued that there are some prima facie reasons to assume (...) that non-cognitivism and error-theory are erroneous. In chapters 2 and 3, I suggest that the two main forms of reductionism, analytic and synthetic reductionism, are mistaken. In chapter 4, I argue that the considerations in the previous chapters in relation to non-cognitivism, error-theory and reductionism provide support to moral realism. It is also suggested that these considerations make it plausible to hypothesise that moral properties depend on non- moral properties in a way I refer to as ‘the realist formula’. The realist formula confirms moral realism since it implies that moral properties are not reducible to non- moral properties. In chapters 5, 6 and 7, I argue that moral realism, much owing to the realist formula, is able to explain significant meta-ethical issues regarding moral disagreement, moral reason and moral motivation. Among other things, externalism concerning moral motivation is defended. The explanatory value of moral realism in relation to these meta-ethical issues is taken to suggest that this view is preferable to non-cognitivism, error-theory and reductionism. Some of the meta-ethical issues discussed in these chapters, particularly moral disagreement and motivation, have been thought to provide support to non-cognitivism and error-theory. I maintain that since realism, unlike reductionism, is able to counter these arguments, it justifies us in upholding the view that moral sentences have truth-value and the view that there are moral properties. In chapter 8, various objections against realism with regard to the dependence of moral properties on non- moral properties are responded to. In chapter 9, I consider an influential argument to the effect that moral properties are not involved in causal explanations. I maintain that this argument fails and that it therefore is reasonable to assume that moral properties are natural properties. However, the discussions in chapters 8 and 9 also suggest that moral realism might face problems that cannot be thoroughly discussed in this thesis. (shrink)

In this paper we shed new light on the Argument from Disagreement by putting it to test in a computer simulation. According to this argument widespread and persistent disagreement on ethical issues indicates that our moral opinions are not influenced by any moral facts, either because no such facts exist or because they are epistemically inaccessible or inefficacious for some other reason. Our simulation shows that if our moral opinions were influenced at least a little bit by moral facts, we (...) would quickly have reached consensus, even if our moral opinions were affected by factors such as false authorities, external political shifts, and random processes. Therefore, since no such consensus has been reached, the simulation gives us increased reason to take seriously the Argument from Disagreement. Our conclusion is however not conclusive; the simulation also indicates what assumptions one has to make in order to reject the Argument from Disagreement. The simulation algorithm we use builds on the work of Hegselmann and Krause (J Artif Soc Social Simul 5(3); 2002, J Artif Soc Social Simul 9(3), 2006). (shrink)
