This paper takes up an important epistemological challenge to the naturalistic moral realist: that her metaphysical commitments are difficult to square with a plausible rationalist view about the epistemology of morality. The paper begins by clarifying and generalizing this challenge. It then illustrates how the generalized challenge can be answered by a form of naturalistic moral realism that I dub joint-carving moral realism. Both my framing of this challenge and my answer advertise the methodological significance of non-fundamental epistemological theorizing, which (...) defends and deploys epistemological claims without adverting to the most fundamental epistemological facts.

Internalism about practical reasons claims that there is a necessary connection between what an agent has reason to do and what he would be motivated to do if he were in privileged or optimal conditions. Internalism is traditionally supported by the claim that it alone can capture two conditions of adequacy for any theory of practical reasons, that reasons must be capable of justifying actions, and that reasons must be capable of explaining intentional acts. Robert Johnson, pp. 53–71) has argued (...) that versions of internalism which avoid obvious problems nevertheless fail to capture both conditions. I argue that Johnson's criticisms rest upon a misinterpretation of the 'explanatory condition', and I proceed to formulate a version of internalism which will allow practical reasons to have both justificatory and explanatory force.

Judgement internalism claims that our evaluative judgements will motivate us to act appropriately, at least in so far as we are rational. I examine how this claim should be understood, with particular focus on whether valuing enjoys a kind of 'normative priority' over desiring. I consider and reject views according to which valuing something provides one with a reason to be moved; this claim of normative priority and the readings of internalism it suggests are too strong. I also reject an (...) interpretation which eschews claims of normative priority, whilst maintaining that valuing nevertheless rationally commits or requires one to be motivated; this rejection of normative priority and the reading of internalism it supports are too weak. In the final sections I sketch the understanding of judgement internalism I favour, and defend it against objections. (shrink)

Ethical non-naturalists often charge that their naturalist competitors cannot adequately explain the distinctive normativity of moral or more broadly practical concepts. I argue that the force of the charge is mitigated, because non-naturalism is ultimately committed to a kind of mysterianism about the metaphysics of practical norms that possesses limited explanatory power. I then show that focusing on comparative judgments about the explanatory power of various metaethical theories raises additional problems for the non-naturalist, and suggest grounds for optimism that a (...) naturalistic realist about practical normativity will ultimately be able to explain the distinctive normativity of practical norms. I then show that radical pluralism or particularism about the structure of normative ethics would complicate the naturalistic strategy that I defend. This suggests a perhaps surprising way in which the resolution of the debate between ethical naturalists and non-naturalists may rest in part on the answers to substantive normative questions.

‘Internalism’ is used in metaethics for a cluster of claims which bear a family resemblance. They tend to link, in some distinctive way—typically modal, mereological, or causal—different parts of the normative realm, or the normative and the psychological. The thesis of this paper is that much metaethical mischief has resulted from philosophers’ neglect of the distinction between two different features of such claims. The first is the modality of the entire claim. The second is the relation between the items specified (...) in the claim. In part one I explain this distinction and the problems neglecting it may cause. In part two I show that it has been neglected, and has caused those problems, at least with respect to one version of internalism. That is judgment internalism, which claims that moral beliefs are necessarily related to pro- or con-attitudes; e.g., that if you believe you ought to x you must have some motivation to x. The considerations standardly adduced in favor of judgment internalism support only a version which lacks the metaethical implications typically attributed to it, at least so far as anyone has shown. Proponents and opponents of judgment internalism fail to realize this because of their neglect of the modality/relation distinction. I illustrate by considering discussions of judgment internalism by Russ Shafer-Landau, Simon Blackburn, James Dreier, David Brink, and others. (shrink)

Semantic normativism, which is the view that semantic properties/concepts are some kind of normative properties/concepts, has become increasingly influential in contemporary meta-semantics. In this paper, I aim to argue that semantic normativism has difficulty accommodating the causal efficacy of semantic properties. In specific, I raise an exclusion problem for semantic normativism, inspired by the exclusion problem in the philosophy of mind. Moreover, I attempt to show that the exclusion problem for semantic normativism is peculiarly troublesome: while we can solve mental-physical (...) exclusion by adopting the so-called ‘autonomy approach’, a similar autonomy solution to semantic exclusion is implausible if semantic properties are understood as normative properties.

This paper examines the idea that ethics might be understood as a domain of straightforwardly empirical inquiry with reference to two of its defenders. Sam Harris has recently urged that ethics is simply the scientific study of welfare and how best to maximize it. That is of course to presuppose the truth of utilitarianism, something Harris considers too obvious to be sensibly contested. Richard Boyd's more nuanced and thoughtful position takes the truth of the ethical theory he favours to be (...) determined by what best explains the success of moral practice over its history. But what is to count here as success is too theory dependent for this to be helpful. From consideration of both Harris and Boyd, the conclusion emerges that once we have satisfied ourselves by ethical reflection about what we ought to do, it may then be a straightforwardly empirical question how to do it, but that arriving at that point, the core concern of the moral philosopher, is far less clearly a straightforwardly empirical affair.

In ‘A Dialogue’, Hume offers an important reply to the moral skeptic. Skeptics traditionally point to instances of moral diversity in support of the claim that our core values are fixed by enculturation. Hume argues that the skeptic exaggerates the amount of variation in moral codes, however, and fails to adopt an indulgent stance toward attitudes different from ours. Hume proposes a charitable interpretation of moral disagreement, moreover, which traces it back to shared principles of human nature. Contemporary philosophers attempt (...) to locate examples of moral variability that cannot be accommodated in this way. But they are no more successful than their predecessors. Moral skeptics have not found a single case of moral diversity that is resistant to the Humean strategy. (shrink)

Normative realists might be assumed to have few worries about semantics. After all, a realist might initially hope to simply adopt the best semantic theory about ordinary descriptive language. However, beginning with the non-cognitivist appropriation of the open question argument, a number of philosophers have posed serious objections to the realist’s ability to offer a plausible semantic theory. This paper introduces the two most influential semantic challenges to normative realism: the open question argument, and the Moral Twin Earth argument. It (...) explains the major replies to these challenges offered by realists, and locates these challenges within the broader debate over what sort of semantic theories might be plausible candidates for a normative realist to adopt.

This article argues that the best way to pursue systematic normative ethical theorizing involves metaethical enquiry. My argument builds upon two central claims. First, I argue that plausible metaethical accounts can have implications that can help to resolve the methodological controversies facing normative ethics. Second, I argue that metaethical research is at least roughly as well supported as normative ethical research. I conclude by examining the implications of my thesis. Inter alia, it shows that the common practice of engaging in (...) systematic normative theorizing uninformed by metaethical commitments offers a significant and troubling hostage to metaethical fortune.

An increasing number of Italian scholars are beginning to share the idea that the conceptual basis of legal positivism (LP) is wrong, particularly in the field of Public Law. According to a group of theories called “neoconstitutionalism,” constitutionalism is to be understood not only as a principle based on the need to impose legal limits to political power, but also as an aggregation of values capable of continually remodelling legal relationships, positioning itself as a “pervasive” point of reference for legal (...) experience. A recent essay by Professor Antonio Baldassarre, President Emeritus of the Constitutional Italian Court, about the “misery of legal positivism” is a good expression of this view. In this article, the ideas outlined by Baldassarre are examined and criticized. The paper also tries to defend a version of legal positivism, which has both a conceptual and prescriptive meaning, relating to decisions made on the basis of rules. This view is based on the two correlated concepts of primary formalism and secondary formalism of “competence and procedure.”. (shrink)

The relationship between ethics and science has been discussed within the framework of continuity versus discontinuity theories, each of which can take several forms. Continuity theorists claim that ethics is a science or at least that it has deep similarities with the modus operandi of science. Discontinuity theorists reject such equivalency, while at the same time many of them claim that ethics does deal with objective truths and universalizable statements, just not in the same sense as science does. I propose (...) here a third view of quasi-continuity (or, equivalently, quasi-discontinuity) that integrates ethics and science as equal partners toward the uncovering of new knowledge. In this third way, a program envisioned by William James but made practicable only by contemporary scientific advancement, science can and must inform ethics at a deep level, and ethical theory— while going beyond science—cannot do without it. In particular, I identify four areas of ethics-science collaboration: neurobiological research into the basis of moral judgment, comparative anthropol- ogy, comparative evolutionary biology of primates, and game-theo- retical modeling. I provide examples within each of these fields to show how they link to ethical theories (including prescriptive work) and questions. The essay concludes with a brief discussion of the light that a scientifically informed ethics can shed on some classical problems in moral theory, such as the relationships between rational- ity and selfishness, egoism and altruism, as well as the concept of social contract. A joint research program involving both philosophers and scientists is called for if we wish to move ethical theory into the twenty-first century. (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. (shrink)

Recently, some philosophers have suggested that a form of robust realism about ethics, or normativity more generally, does not face a significant explanatory burden in metaphysics. I call this view metaphysically quietist normative realism . This paper argues that while this view can appear to constitute an attractive alternative to more traditional forms of normative realism, it cannot deliver on this promise. I examine Scanlon’s attempt to defend such a quietist realism, and argue that rather than silencing metaphysical questions about (...) normative reasons, his defense at best succeeds only in shifting the focus of metaphysical enquiry. I then set aside the details of Scanlon’s view, and argue on general grounds that that the quietist realist cannot finesse a crucial metanormative task: to explain the contrast between the correct normative system and alternative putatively normative standards.

According to the Desire-Based Reasons Model reasons for action are provided by desires. Many, however, are critical about the Model holding an alternative view of practical reason, which is often called valued-based. In this paper I consider one particular attempt to refute the Model, which advocates of the valued-based view often appeal to: the idea of reason-based desires. The argument is built up from two premises. The first claims that desires are states that we have reason to have. The second (...) argues that desires do not add to the stock of reasons the agent has for having them. Together the two theses entail that desires are based on reasons, which they transmit but to which they cannot add. In the paper I deal with a counterexample to the second premise: tie-breaking desires. I first distinguish two interesting cases and argue that only the second challenges the premise. Then I move onto analyze this challenge by focusing on Ruth Chang’s recent employment of it. I show that contrary to its counterintuitive appearance, the challenge can be sustained. However, I also argue that Chang overlooks the full potential of one particular response to the challenge: the introduction of higher-order reasons determining the normative significance of these desires. At the same time, I show that this response has a problem that Chang does not consider. As a result, the response can only partially disarm the challenge of tie-breaking desires; or not at all, depending on what significance we attribute to the counterexamples. (shrink)

I argue that motivational internalism should not be driving metaethics. I first show that many arguments for motivational internalism beg the question by resting on an illicit appeal to internalist assumptions about the nature of reasons. Then I make a distinction between weak internalism and the weakest form of internalism. Weak internalism allows that agents fail to act according to their normative judgments when they are practically irrational. I show that when we clarify the notion of practical irrationality it does (...) not support motivational internalism. Weakest internalism only claims that agents are irrational if they entirely lack motivation to do what they judge they ought to. I do not argue against weakest internalism, but I argue that it is not an important view. (shrink)

In this paper I analyze the tension between realism and antirealism at the basis of Kantian constructivism. This tension generates a conflictive account of the source of the validity of social norms. On the one hand, the claim to moral objectivity characteristic of Kantian moral theories makes the validity of norms depend on realist assumptions concerning the existence of shared fundamental interests among all rational human beings. I illustrate this claim through a comparison of the approaches of Rawls, Habermas and (...) Scanlon. On the other hand, however, objections to moral realism motivate many Kantian constructivists to endorse the antirealist claim that reasonable agreement is the source of the validity of social norms. After analyzing the difficulties in the latter strategy, I try to show how a balance between the realist and antirealist elements of Kantian constructivism can be reached by drawing a sharper distinction between the justice and the legitimacy of social norms.

The traditional conception of response-dependence isinadequate because it cannot account for all intuitivecases of response-dependence. In particular, it is unableto account for the response-dependence of (aesthetic, moral, epistemic ...) values. I therefore propose tosupplement the traditional conception with an alternativeone. My claim is that only a combination of the twoconceptions is able to account for all intuitivecases of response-dependence.

In this paper, I make explicit some implicit commitments to realism and conceptualism in recent work in social epistemology exemplified by Miranda Fricker and Charles Mills. I offer a survey of recent writings at the intersection of social epistemology, feminism, and critical race theory, showing that commitments to realism and conceptualism are at once implied yet undertheorized in the existing literature. I go on to offer an explicit defense of these commitments by drawing from the epistemological framework of John McDowell, (...) demonstrating the relevance of the metaphor of the “space of reasons” for theorizing and criticizing instances of epistemic injustice. I then point out how McDowell’s own view requires expansion and revision in light of Mills' concept of 'epistemologies of ignorance'. I conclude that, when their strengths are used to make up for each others' weaknesses, Mills and McDowell’s positions mutually reinforce one another, producing a powerful model for theorizing instances of systematic ignorance and false belief.

Moral rationalists and sentimentalists traditionally disagree on at least two counts, namely regarding the source of moral knowledge or moral judgements and regarding the source of moral motivation. I will argue that even though Leibniz's moral epistemology is very much in line with that of mainstream moral rationalists, his account of moral motivation is better characterized as sentimentalist. Just like Hume, Leibniz denies that there is a necessary connection between knowing that something is right and the motivation to act accordingly. (...) Instead, he believes that certain affections are necessary for moral motivation. On my interpretation, then, Leibniz is an externalist about judgements and motivation: he is committed to a gap between the judgement that something is morally right and the motivation to act accordingly. As a matter of fact, I will argue that there are two gaps. The first and less controversial one has to do with the fact that Leibniz reconciles his psychological egoism with ethical altruis..

An overview of Dai's ethics, highlighting some overlooked or misunderstood theses on moral deliberation and motivation.

Internalists argue that there is a necessary connection between motivation and moral judgment. The examination of cases plays an important role in philosophical debate about internalism. This debate has focused on cases concerning the failure to act in accordance with a moral judgment, for one reason or another. I call these failure cases . I argue that a different sort of case is also relevant to this debate. This sort of case is characterized by (1) moral judgment and (2) behavior (...) that accords with the content of the moral judgment but that has been performed not because of the moral judgment. Instead it is due to some other source of motivation. I call these alternative motivation cases . I distinguish two sorts of alternative motivation cases, and I argue that externalists have natural explanations of these cases. By contrast, extant internalist accounts of failure cases are inadequate when applied to alternative motivation cases. (shrink)

In Ruling Passions, Simon Blackburn contends that we should reject sensibility theory because it serves to support a conservative complacency. Blackburn's strategy is attractive in that it seeks to win this metaethical dispute – which ultimately stems from a deep disagreement over antireductionism – on the basis of an uncontroversial normative consideration. Therefore, Blackburn seems to offer an easy solution to an apparently intractable debate. We will show, however, that Blackburn's argument against sensibility theory does not succeed; it is no (...) more supportive of conservative complacency than Blackburn's noncognitivism. A victory for noncognitivism cannot be so easily won. (shrink)

In recent attempts to characterize the cognitive mechanisms underlying altruistic motivation, one central question is the extent to which the capacity for altruism depends on the capacity for understanding other minds, or ‘mindreading’. Some theorists maintain that the capacity for altruism is independent of any capacity for mindreading; others maintain that the capacity for altruism depends on fairly sophisticated mindreading skills. I argue that none of the prevailing accounts is adequate. Rather, I argue that altruistic motivation depends on a basic (...) affective system, a ‘Concern Mechanism’, which requires only a minimal capacity for mindreading. (shrink)

This essay explicates and assesses Yeshayahu Leibowitz's axiology, and its relation to the value he claims halakhic practice instantiates: service of God. It argues that, while Leibowitz often affirms a relativist “polytheism of values,” he sometimes implies that the religious value is the “most valuable value.” However, this is not due to its material content, because serving God is objectively best; rather it is because, consonant with his negative theology, it most fully instantiates the formal properties of a value. The (...) essay concludes by assessing the tenability of Leibowitz's metaethics as well as the argument for positing this contentless value as an intention and reason for halakhic practice. (shrink)

Derek Parfit claims that “Williams and Mackie…do not use the normative concepts that I and other Non-Naturalists use.” Whatever we think of Parfit’s interpretation of Williams, his interpretation of Mackie should be rejected. For understandable historical reasons, Mackie’s texts are ambiguous. But if we apply to the interpretation of Mackie the same principle of charity Parfit employs in interpreting Williams, we find decisive reason to interpret Mackie as using the same normative concepts as Non-Naturalists.

Discussion of moral explanation has reached animpasse, with proponents of contemporaryethical naturalism upholding the explanatoryintegrity of moral facts and properties, andopponents – including both anti-realists andnon-naturalistic realists – insisting thatsuch robustly explanatory pretensions as moraltheory has be explained away. I propose thatthe key to solving the problem lies in thequestion whether instances of moral propertiesare causally efficacious. It is argued that,given the truth of contemporary ethicalnaturalism, moral properties are causallyefficacious if the properties of the specialsciences are. Certain objections are rebuttedinvolving (...) the nature of causation, on the onehand, and putative special features of themoral realm, on the other. (shrink)

Even the most sympathetic readers of Kant's moral philosophy usually disagree with him about some aspect of his theory, or some particular moral judgement. His unqualified condemnation of lying in the essay ‘On a supposed right to lie from philanthropy’ is a classical case in question, as is his strong endorsement of retributive justice and the death penalty. A third prominent source of discontent are Kant's repeated verdicts on the moral status of non-human animals, or rather the lack thereof. For, (...) despite the fact that his practical recommendations in this field are sensible and even progressive, he repeatedly insists that there are no direct duties to animals, that the well-being of animals is morally indifferent, in particular that we ought to treat animals decently solely for the sake of humanity. As a result, the foundations of his advice seem morally inadequate, even offensive. (shrink)

In this paper I compare and contrast Rawls’s notion of reflective equilibrium with Wellman‘s notion of conductive argument. In the course of so doing I will address two key questions: Are conduc-tive argument and reflective equilibrium best understood as modes of reasoning or types of argument? and What relationship, if any, is there between them?

Suppose an agent has made a judgement of the form, 'all things considered, it would be better for me to do a rather than b (or any range of alternatives to doing a)' where a and b stand for particular actions. If she does not act upon her judgement in these circumstances would that be a failure of rationality on her part? In this paper I consider two different interpretations of all things considered judgements which give different answers to this (...) question, one suggested by Donald Davidson, the other by Paul Grice and Judith Baker. I argue that neither interpretation is adequate. However, a third interpretation that combines features of the Grice/Baker view with the Davidsonian view is possible. In the final section of the paper I defend this interpretation against two objections. (shrink)

I argue that Mackie's approach to practical reasons is attractive and unjustly neglected. In particular I argue that it is much more plausible than the kind of instrumentalist approach famously articulated by Bernard Williams. This matters for Mackie's arguments for moral skepticism. Contra Richard Joyce, I argue that it is a serious mistake to invoke instrumentalism in arguing for moral skepticism.

Pour contrer le scepticisme au sujet de la connaissance des valeurs, la plupart soutiennent avec John Rawls qu’une croyance comme celle qu’une action est bonne est justifiée dans la mesure où elle appartient à un ensemble de croyances cohérent, ayant atteint un équilibre réfléchi.

Much recent philosophical literature on happiness and satisfaction is based on the belief that empirical research is relevant to philosophical conclusions. In his2010 book What is This Thing Called Happiness? Fred Feldman begs to differ. He suggests that there is no evidence that empirical research is relevant to long-standing philosophical questions; consequently, that philosophers have little reason to pay attention to the work of psychologists or economists; and that philosophers need not fear embarrassing themselves by being ignorant of important scientific (...) findings that bear directly on their work. Relying on an example invoked by Feldman himself, this paper makes the case that all three theses are false. The argument suggests a picture according to which science and philosophy stand in a symbiotic relationship, with scientists and philosophers engaging in a mutually beneficial exchange of ideas for the advancement of thegeneral knowledge.

This essay offers a defence of the non-cognitivist approach to the interpretation of moral judgments as disguised imperatives corresponding to social rules. It addresses the body of criticism that faced R. M. Hare, and that currently faces moral anti-realists, on two levels, by providing a full semantic analysis of evaluative judgments and by arguing that anti-realism is compatible with moral aspiration despite the non-existence of obligations as the externalist imagines them. A moral judgment consists of separate descriptive and prescriptive components (...) and is to be understood as a declarative statement prefaced by an 'ideality operator'. Moral beliefs are genuinely representational, but their truth conditions can only be stated with reference to imaginary ideal worlds. Moral judgments are neither confirmed nor verified, but alternative moral positions are preferentially endorsed and adopted by individual agents on the basis of their perceived all-things-considered optimality. High aspiration moralities are normally very costly to agents in terms of their prudential and aesthetic interests, but they are theoretically as eligible as the adoption of other, less demanding sets of rules.

Could someone who wants a gin and tonic have a normative reason to drink petrol and tonic? Bernard Williams and Michael Smith both say, 'No'. They argue that what an agent has normative reason to do is determined by rational deliberation that involves correcting the agent's beliefs and current motivations. On such an account of normative reasons, an agent who is motivated to act in some way due to a false belief does not have reason to act in that way. (...) I argue that the agent could have reason to drink the petrol, because an agent's epistemic circumstances, what that agent can come to know, can be as relevant to what the agent has reason to do as other aspects of his circumstances. Moreover, if an agent's epistemic circumstances are taken into account when determining what the agent has reason to do, this can still give an account of reasons that is normative, ensures that the agent and onlookers agree on what the agent has reason to do, is appropriately connected to rationality and fairly represents the agent's beliefs about the knowledge they need to have to know how they have reason to act.

David Papineau’s model of scientific reduction, contrary to his intent, appears to enable a naturalist realist account of the primitive normativity involved in a biological adaptation’s being “for” this or that (say the eye’s being for seeing). By disabling the crucial anti-naturalist arguments against any such reduction, his model would support a cognitivist semantics for normative claims like “The heart is for pumping blood, and defective if it doesn’t.” No moral claim would follow, certainly. Nonetheless, by thus “pressing from below” (...) we may learn something about moral normativity. For instance, suppose non-cognitivists like Mackie are right that the semantics of normative claims should be “unified”: if the semantics of moral claims is non-cognitivist, so too is that of all normative claims. Then, assuming that a naturalist reduction does yield a sound cognitivist account of the primitive normativity, it would follow that our semantics of moral claims is cognitivist as well. (shrink)

I here defend my earlier doubts that VM patients serve as counterexamples to motivational internalism by highlighting the difficulties of belief attribution in light of holism about the mental and by suggesting that a better understanding of the role of emotions in the self-attribution of moral belief places my earlier Davidsonian "theory of mind" argument in a clearer light.

Manuscript based on address delivered February, 1998 at the Annual Meeting of the Association of Practical and Professional Ethics, Dallas, Texas.

One of the most important issues in moral philosophy is whether morality can be justified by rationality. The purpose of this study is to examine Gauthier’s moral theory, focusing on the disposition of constrained maximization, which is the main thrust of his project to justify morality rationally. First of all, I shall investigate Gauthier’s assumption and condition for the rationality of the disposition of constrained maximization so as to disclose that the disposition of constrained maximization is not necessarily chosen by (...) rational agents. Then I shall explore his other arguments including ones for the reinterpretation of rationality and the self-critical reflection of rational beings, which can be considered as his further efforts to make the disposition of constrained maximization a rational choice. By exploring them, I shall attempt to indicate that those arguments are not valid so long as he clings to the maximizing conception of rationality and thereby this conception of rationality itself is not enough to provide morality with a basis.
