Modal metaphysics consumed much of the philosophical discussion at the turn of the century, yielding a number of epistemological insights. Modal analyses were applied within epistemology, yielding sensitivity and safety theories of knowledge as well as counterfactual accounts of the basing relation. The contemporary conversation has now turned to a new metaphysical notion – grounding – opening the way to a fresh wave of insights by bringing grounding into epistemology. In this paper, I attempt one such application, making sense of (...) the epistemic regress problem in terms of grounding. I argue that the relation that generates the epistemic regress is a grounding relation, showing that grounding can make sense of proposals by epistemic foundationalists and charting the course for similar applications to epistemic coherentism and epistemic infinitism. If it is right that grounding is involved in the epistemic regress, this points the way forward both for epistemologists and metaphysicians, revealing the prospects of solutions to the epistemic regress problem while providing grounding advocates with yet another example of grounding with which to theorize.

This chapter develops Moral Occasionalism, according to which moral facts are grounded in certain natural facts, which are called sub-moral grounds, and these sub-moral grounds influence us in such a way as to induce largely correct moral beliefs. Moral Occasionalism is designed to explain the correlation of moral beliefs with the moral facts—and to do so in a way that is consistent with non-interactionist views, according to which moral facts neither influence nor are influenced by moral beliefs. It is argued (...) that moral non-naturalists and others who are committed to non-interactionist views ought to be in the business of defending Moral Occasionalism. The chapter shows that Moral Occasionalism has major advantages over its chief non-interactionist rival, namely David Enoch’s “godless pre-established harmony” view. The chapter anticipates and responds to several objections. (shrink)

What makes some acts morally right and others morally wrong? Traditionally, philosophers have thought that in order to answer this question we must find and formulate exceptionless moral principles—principles that capture all and only morally right actions. Utilitarianism and Kantianism are paradigmatic examples of such attempts. In recent years, however, there has been a growing interest in a novel approach—Particularism—although its precise content is still a matter of controversy. In this paper I develop and motivate a new formulation of particularism (...) as a research program and I show that my formulation is not vulnerable to the most common objections to particularism. Moreover, I argue that the particularist research program shows enough promise to warrant further exploration. (shrink)

The aim of this article is to review the recent popularity of casuistry as a model of moral inquiry. I argue that proponents of casuistry do not endorse the particularist epistemology that seems to be implied by their position, and that this is why casuistry does not seem to present something really new in comparison to 'top-down' generalist approaches. I contend that casuistry should develop itself as a (moderately) particularist position and that the challenge for the defender of casuistry is (...) to come up with ideas that strengthen the ('intuitionist') model of rationality that underlies most forms of particularism. (shrink)

I take the debate between the particularists and the principlists to be centered on the issue of whether there are true moral principles. One argument the principlists often appeal to in support of their claim that there are true moral principles is the argument from supervenience. Roughly, the argument is made up of the following three statements: (P1) If the thesis of moral supervenience holds, then there are true moral principles. (P2) The thesis of moral supervenience holds. (C) There are (...) true moral principles, and hence particularism is false. In this paper, I argue that the above argument is not sound by attacking (P1). I hold that no general supervenient/resultance base has a robust enough configuration of contextual features as to ground the existence of true moral principles. If I am right about this, I think it would be indicative of a reason to be less confident about the truth of principlism and more confident about the truth of particularism. (shrink)

Inspired by an analogy between moral and secondary properties, some moral philosophers have argued that moral properties are dispositions. According to one version of this view, most clearly represented by Jonathan Dancy, a moral property is the property of being such, having base properties such, that an entity with the property elicits morally merited and motivating responses. Its proponents have argued that this notion can explain how moral judgements can be objective in the sense of expressing properties that are independent (...) of will and yet imply motivation by those who assert them. In special consideration of Dancy’s Moral Reasons, I argue that the dispositional account does not save the idea of objectivity in the required sense and implies an untenable view of moral motivation. I therefore conclude that the dispositional account fails to explain the two features of moral judgements. (shrink)

What is required for one thing to be a reason for another? Must the reason, more precisely, be or involve a principle? In this essay I target the idea that justification via reasons of one's beliefs (e.g., epistemic or moral) requires that the 'justifying reasons' be or involve (substantive and significant) principles. I identify and explore some potential sources of a principles requirement, and conclude that none of them (i.e., the normative function of reasons, the abstract structure of reasons, the (...) universalizability constraint on [moral] reasons, and even the pragmatic considerations that attenuate 'real-world' reason-giving) mandate that reasons be principles. I then explore implications of this conclusion, and note especially the resultant and paradoxical permissibility of justifying reasons that manage to be lawlike (a sine qua non for justifying reasons) even while consisting of highly-detailed and situation-specific proposition sets, e.g., novel-length narratives.

There is an obvious affinity between virtue ethics and particularism. Both stress the complexify of the moral life, the inadequacy of rule-following as a guide to moral deliberation, and the importance of judgement in discerning the morally relevant features of particular situations. Yet it remains an open question how deep the affinity goes. I argue that the radical form of particularism defended by Jonathan Dancy has surprisingly strong implications for virtue ethics. Adopting such a view would require the virtue theorist (...) either to adopt an unattractive model of moral motivation or to embrace a fairly strong version of the unity of the virtues. (shrink)

The traditional conception of ethical theory sees it as the project of developing a coherent set of rules from which one can infer all determinate moral verdicts. I am not optimistic about the prospects for constructing such a theory. To explain this pessimism, we need to understand what moral rules are and what roles they might play in ethical theory.

Jonathan Dancy has developed a very refined theory called ethical particularism. He has argued extensively for the metaphysical part of his position. However, the accompanying epistemology is not yet clear. In this paper I will sketch a particularist epistemology that is consistent with Dancy’s particularist metaphysics, although my approach differs in certain respects from epistemological claims Dancy has made. I will defend an epistemology that states: 1. that moral knowledge is based on intuitions and 2. that we need emotions in (...) order to have moral knowledge. I will call this approach ‘affectual intuitionism’. Dancy rejects both claims, but I will argue that his arguments against these claims are not convincing. (shrink)

What place, if any, moral principles should or do have in moral life has been a longstanding question for moral philosophy. For some, the proposition that moral philosophy should strive to articulate moral principles has been an article of faith. At least since Aristotle, however, there has been a rich counter-tradition that questions the possibility or value of trying to capture morality in principled terms. In recent years, philosophers who question principled approaches to morality have argued under the banner of (...) moral particularism. Particularists can be found in diverse areas of philosophical inquiry, and their positions and arguments are of broad interest.1 Despite its importance, a proper evaluation of particularism has been hindered both by the diversity of arguments employed to defend it, and, perhaps more significantly, by the diversity of positions that can fairly claim to be particularist. Our aim is first to explicate particularism by identifying a unified range of particularist theses and explaining both what unites them as versions of particularism as well as what distinguishes them from each other. We then articulate and evaluate the main arguments for particularism and explain how each is especially well-suited to supporting some conceptions of particularism rather than others. We tentatively conclude that the positive arguments for particularism are not convincing. They do, however, reveal particularism to be a surprisingly resilient position, one that is not readily refuted.. (shrink)

Modern philosophers normally either reject the „divine command theory” of ethics and argue that moral duties are independent of any commands, or make it dependent on God's commands but like Robert Adams modify their theory and identify moral duties in terms of the commands of a loving God. Adams regards this theory as metaphysically necessary. That is, if it is true, it is true in all possible worlds. But Swinburne's position is unprecedented insofar as he regards moral truths as analytically (...) necessary. In this paper Swinburne's argument will be discussed and I will reveal some of the difficulties involved in categorising general moral principles as logical truths. (shrink)

All’inizio degli anni Sessanta Frank Sibley pubblicava un articolo dal titolo inequivocabile, Aesthetic and Non Aesthetic; in esso, riprendendo alcuni spunti presenti in un altro suo celebre articolo, precedente di pochi anni, il filosofo americano affrontava esplicitamente il problema del rapporto tra giudizi, qualità, descrizioni e concetti estetici e non estetici. Aveva così inizio un dibattito tra i più fecondi sviluppatisi in seno all’estetica analitica, dibattito che ancora oggi è al ce...

RÉSUMÉ: Plusieurs libéraux modernes soutiennent que le pluralisme des valeurs a d’importantes conséquences pour l’élaboration des procédures et des institutions politiques. Mais les arguments fondés sur l’incommensurabilité et sur l’indétermination de la rationalité ou de la délibération se révèlent tous compatibles avec le monisme; et certaines formes de pluralisme sont compatibles soit avec une hiérarchisation des valeurs soit avec une hiérarchisation méta-éthique de certains types de concepts normatifs. En outre le «pluralisme» en tant que thèse métaphysique concernant les valeurs est (...) souvent confondu avec la thèse descriptive qu’il existe une pluralité de conceptions du bien dans les sociétés modernes, qui, elle, fournit la véritable justification du libéralisme dans l’organisation politique. Or cette forme de pluralisme est également compatible avec le monisme des valeurs. Le libéral pluraliste se trouve ainsi confronté à un dilemme: soit certaines valeurs sont d’importance prioritaire pour la justification de l’organisation politique, soit les conséquences du pluralisme des valeurs en pareil domaine sont indéterminées.

Contingent negative existentials give rise to a notorious paradox. I formulate a version in terms of metaphysical grounding: nonexistence can't be fundamental, but nothing can ground it. I then argue for a new kind of solution, expanding on work by Kit Fine. The key idea is that negative existentials are contingently zero-grounded – that is to say, they are grounded, but not by anything, and only in the right conditions. If this is correct, it follows that grounding cannot be an (...) internal relation, and that no complete account of reality can be purely fundamental. (shrink)

Many non-naturalists about the normative want to endorse the view that some normative facts hold in virtue of both non-normative facts and normative principles. In this paper, I argue that non-naturalism is inconsistent with this thesis, due to the nature of normative principles and their grounds. I then consider two ways in which the nonnaturalist position could be modified or expanded to solve this problem. No solution, it turns out, is without its problems. I end by considering how the non-naturalist (...) can deny that normative facts obtain partially in virtue of principles. (shrink)

According to Jonathan Dancy's moral particularism, the way in which a given moral reason functions as a reason for or against an action can vary from case to case. Dancy also asserts that reasons are resultance bases. But a reason why something ought to be done is that in virtue of which it is something that ought to be done. If the function of a reason can vary, then resultance bases cannot be reasons. Perhaps the particularist might conceive a reason (...) not as a resultance base, but as a specific type of which a resultance base is a token. But this picture of reasons cannot be correct.

With regard to intrinsically morally relevant factors it is natural to suppose that if a variation in a given factor makes a moral difference anywhere, then it makes the same moral difference everywhere (henceforth: the constancy assumption). Jonathan Dancy (and other moral particularists) reject the constancy assumption. Partly on the basis thereof, they infer that ethical decisions should be made “case by case, without the comforting support of moral principles”. In this article, I challenge Dancy's defence and use of a (...) denial of the constancy assumption on three points. First, Dancy's appeal to moral intuitions do not justify denying a significant version of the constancy assumption. Second, if we reject the constancy assumption, surprisingly, it may in one crucial respect be very hard to defend moral particularism as commonly articulated. Third, rejecting the constancy assumption does not motivate seeing moral reasoning as essentially a case‐by‐case matter. (shrink)

Jonna Vance and Preston Werner argue that humans’ mechanisms of perceptual attention tend to be sensitive to morally relevant properties. They dub this tendency “Attentional Moral Perception” (AMP) and argue that it can play all the explanatory roles that some theorists have hoped moral perception can play. In this article, I argue that, although AMP can indeed play some important explanatory roles, there are certain crucial things that AMP cannot do. Firstly, many theorists appeal to moral perception to explain how (...) moral knowledge is possible. I argue that AMP cannot put an agent in a position to acquire moral knowledge unless it is supplemented with some other capacity for becoming aware of moral properties. Secondly, theorists appeal to moral perception to explain “moral conversions”, i.e., cases in which an experience leads an agent to form a moral belief that conflicts with her pre-existing moral beliefs. I argue that AMP cannot explain this either. Due to these shortcomings, theorists should turn to emotions for a powerful and psychologically realistic account of virtuous agents’ sensitivity to the moral landscape. (shrink)

Early twentieth-century philosophers of perception presented their naïve realist views of perceptual experience in anti-Kantian terms. For they took naïve realism about perceptual experience to be incompatible with Kant’s claims about the way the understanding is necessarily involved in perceptual consciousness. This essay seeks to situate a naïve realist account of visual experience within a recognisably Kantian framework by arguing that a naïve realist account of visual experience is compatible with the claim that the understanding is necessarily involved in the (...) perceptual experience of those rational beings with discursive intellects. The resultant view is middle way between recent conceptualist and non-conceptualist interpretations of Kant, holding that the understanding is necessarily involved in the kind of perceptual consciousness that we, as rational beings, enjoy whilst allowing that the relations of apprehension which constitute perceptual consciousness are independent of acts of the understanding.

In this paper I critically examine the implications of the uncodifiability thesis for principlism as a pluralistic and non-absolute generalist ethical theory. In this regard, I begin with a brief overview of W.D. Ross’s ethical theory and his focus on general but defeasible prima facie principles before turning to 2) the revival of principlism in contemporary bioethics through the influential work of Tom Beauchamp and James Childress; 3) the widespread adoption of specification as a response to the indeterminacy of abstract (...) general principles and the limitations of balancing and deductive approaches; 4) the challenges raised to fully specified principlism by the uncodifiability thesis and 5) finally offer a defense of the uncodifiability thesis against various critiques that have been raised.

The paper aims at meeting Blackburn’s challenge to explain the non-reductive supervenience of moral predicates on natural ones. It offers a critical examination of Hare’s model of moral thinking which can be used as a candidate for such an explanation. It is argued that, as it stands, Hare’s model fails to meet Blackburn’s challenge. Yet some revisions of the model are suggested, and it is claimed that the improved version does supply the required explanation. The model suggested in the paper (...) carries a meta-ethical implication concerning the superiority of the anti-realist understanding of moral discourse. (shrink)

Gideon Rosen and Robert Schwartzkopff have independently suggested (variants of) the following claim, which is a varian of Hume's Principle: -/- When the number of Fs is identical to the number of Gs, this fact is grounded by the fact that there is a one-to-one correspondence between the Fs and Gs. -/- My paper is a detailed critique of the proposal. I don't find any decisive refutation of the proposal. At the same time, it has some consequences which many will (...) find objectionable. (shrink)

Christine Korsgaard sees normative generalizations as provisionally universal, in the sense that exceptions to them have reasons for being exceptions and that they could in principle be revised into more specific and precise absolutely universal rules. Do exceptions to normative generalizations have such explanations? Can such generalizations always be revised into or replaced by absolutely universal rules? The answer depends on the structure of practical space, and, specifically, the degree to which normative relations are definable. Distinguishing degrees of definability in (...) practical space opens up paths for generalist and particularist conceptions of normativity. (shrink)

I argue—contra moderate grounding pluralists such as Kit Fine and more extreme grounding pluralists such as Jessica Wilson—that there is fundamentally only one grounding/in-virtue-of relation. I also argue that this single relation is indispensable for normative theorizing—that we can’t make sense of, for example, the debate over consequentialism without it. It follows from what I argue that there is no metaethically-pure normative ethics.

Moral particularists argue that because reasons for action are irreducibly context-dependent, the traditional quest in ethics for true and exceptionless moral principles is hopelessly misguided. In making this claim, particularists assume a general framework according to which reasons are the ground floor normative units undergirding all other normative properties and relations. They then argue that there is no cashing out in finite terms either (i) when a given non-normative feature gives rise to a reason for or against action, or (ii) (...) how the reasons that are present in a given context play off each other to determine one’s overall duties. However, the conjunction of these two theses leaves particularists without a coherent notion of a reason for action: posit too much irreducible context-dependence in the behavior of reasons, and the reasons-based framework breaks down. One upshot is that the particularists’ challenge to principle-based approaches to ethics has not, at present, been successfully made out; another upshot is that perhaps the best way to formulate that challenge involves renouncing the reasons-based framework all together.

Some opponents of ethical particularism complain that particularists cannot give a plausible account of moral education. After considering and rejecting a number of arguments to this conclusion, I focus on the following objection: Particularism, at least in Jonathan Dancy's version, has nothing to say about moral education because it lacks a substantial account of moral competence. By Dancy's own admission, particularists can tell us little more than that a competent agent 'gets things right case by case'. I respond by reflecting (...) on how we want our children to turn out, morally speaking. I argue that we can present a compelling story about our aspirations for our children's moral development that is consistent with particularism and that provides the beginnings of a plausible account of the competence we look to moral education to instil.

Expressivists traditionally explain normative supervenience by saying it is a conceptual truth. I argue against this tradition in two steps. First, I show the modal claim that stands in need of explanation has been stated imprecisely. Classic arguments in metaethics for normative supervenience and those that rely on it as a premise presuppose a constraint on the supervenience base that is rarely (if ever) made explicit: the repeatability of the non-normative properties on which the normative supervenes. Non-normative properties are repeatable (...) when it is possible for numerically distinct individuals to share them. Second, I show if the modal truth that stands in need of explanation entails that there are individuals exactly alike in repeatable non-normative respects that cannot normatively differ, then standard expressivist accounts of normative supervenience as a conceptual truth are unsuccessful. Expressivist metasemantics for normative terms, together with constitutive facts about the non-cognitive attitudes essentially involved in normative thought, strongly suggest that repeatable supervenience could not be a conceptual truth. I argue, finally, that although repeatable supervenience bears the marks of a conceptual truth, expressivists should be content to treat it as an ordinary normative truth, and to explain it the same way they explain other normative truths.

This essay defends a three-dimensional response-model theory of recognition of persons, and discusses the related phenomenon of recognition of reasons, values and principles. The theory is three-dimensional in endorsing recognition of the equality of persons and two kinds of relevant differences: merits and special relationships. It defends a ‘response-model’ which holds that adequacy of recognition of persons is a matter of adequate responsiveness to situation-specific reasons and requirements. This three-dimen- sional response-model is compared to Peter Jones’s view, which draws the (...) distinction between status and merit recognition, and mediated and unmediated recognition. The essay discusses a number of questions related to how recognition of situation-specific reasons, and more general values and principles, is related to recognition of persons. The three- dimensional response-model of recognition of persons is in principle compatible with a constructivist view, which holds that the validity of values and principles is dependent on acknowledgement or endorsement. But even if one is a realist on that issue and thinks of validity as independent of acknowledgement, acknowledging relevant values, reasons and principles is a hugely important precondition of actual interpersonal recognition. The essay analyses these connections. (shrink)

According to contemporary moral realism a moral property, like goodness or badness, is either a natural property or a non-natural property of actions or situations. Contemporary moral naturalists like Richard Boyd, Nicholas Sturgeon, and David Brink are a group of philosophers who are often referred to as Cornell realists because of their connection with Cornell University. Frank Jackson is another contemporary moral naturalist who is one of the leaders of The Canberra Planners at the Australian National University with which he (...) is connected. Jackson defends “the most extreme form of naturalism.” Jackson’s view is considered extremeby those who disagree with him because he believes that moral properties are reducible or identical to natural properties. This view of Jackson is opposed by contemporary non-naturalists like Jonathan Dancy, Derek Parfit, and Russ Shafer-Landau for reasons which in my view are not successful. Despite Jackson’s reductionism about the ethical, the Cornell realists, nevertheless, agree with him that moral properties are natural properties. (shrink)

Is it possible to show that a moral claim is mistaken without taking a moral stand with regard to it? A striking number of contemporary metaethicists suppose that it is. In this paper, I argue against a prominent line of support for this supposition. My goal is to cast suspicion on a general tendency to think that the epistemic standing of moral claims is something that can be assessed from outside the practices of making and critically evaluating moral judgements. I (...) do this by focusing on a widely accepted criterion of competence with regard to the use of moral concepts, the moral supervenience criterion (MSC). This criterion holds that someone who judges two acts or events to be morally different without thinking that he has to identify some non-particular non-moral difference between them simply doesn't understand what it is to make a moral judgement. I focus on a paradigmatic example of the sort of mistake in moral judgement that is supposed to support the MSC and argue that it provides no support whatsoever. I then offer my own alternative explanation of this sort of mistake in moral judgement. I conclude with a discussion of why advocates of the MSC are inclined to suppose that it is possible to assess the epistemic standing of a moral claim without oneself taking a moral stand with regard to it.

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)

The phrase ‘in virtue of’ is a mainstay of metaphysical discourse. In recent years, many philosophers have argued that we should understand this phrase, as metaphysicians use it, in terms of a concept of metaphysical dependence called ‘grounding’.This dissertation explores a range of central issues in the theory of grounding. Chapter 1 introduces the intuitive concept of grounding and discusses some compulsory questions in the theory of grounding. Chapter 2 focusses on scepticism on grounding, according to which the recent philosophical (...) interest in the topic is misguided. In chapter 3 I discuss grounding’s explanatory roles. Chapter 4 focusses on the claim that if an entity is grounded then it is an ontological free lunch. Chapter 5 discusses and rejects the claim that groundingis a relation between facts. This conclusion raises a problem: if grounding is not a relation between facts it becomes difficult to specify the connections between grounding and explanation and grounding and necessity. But not only is it desirable to specify these relations, it is essential for establishing that grounding is able to play the explanatory roles that are discussed in chapter 3. Chapter 6 responds to this problem by outlining an approach to grounding based on David Lewis’s (2003) theory of truthmaking. Against this backdrop I discuss, in chapter 7, some issues in the logic of grounding. (shrink)

In this paper I explore the implications of moral vagueness (viz., the vagueness of moral predicates) for non-naturalist metaethical theories like those recently championed by Shafer-Landau, Parfit, and others. I characterise non-naturalism in terms of its commitment to 7 theses: Cognitivism, Correspondence, Atomism, Objectivism, Supervenience, Non-reductivism, and Rationalism. I start by offering a number of reasons for thinking that moral predicates are vague in the same way in which ‘red’, ‘tall’, and ‘heap’ are said to be. I then argue that (...) the moral non-naturalist seeking to countenance moral vagueness faces a dilemma: are moral properties vague, or perfectly sharp? On either horn of the dilemma, serious problems arise for some of the central tenets of non-naturalism: vague properties seem to threaten Objectivism, Supervenience, and Non-reductivism; on the other hand, sharp properties raise problems for Supervenience and Rationalism. The difficulties on each horn of the dilemma are real, and while they may not be insuperable, they do, at the very least, drastically limit the things non-naturalists can consistently say about moral properties, facts, and reasons.

Critics often argue that Ross’s metaphysical and epistemological accounts of all-things-considered duties suffer from the problem of explanation. For Ross did not give us any clear explanation of the combination of pro tanto duties, i.e. how principles of pro tanto duties can combine. Following from this, he did not explain how we could arrive at overall justified moral judgements. In this paper, I will argue that the problem of explanation is not compelling. First of all, it is based on the (...) classical account of pro tanto duties. Principles of pro tanto duties can be understood in another way, i.e. in terms of reason-giving account that might be of help to provide a response to the critics. Furthermore, critics fail to see some evidence in Ross about how we can arrive at moral judgements. (shrink)
