Nihilism, Nietzsche and the Doppelganger Problem Was Nietzsche a nihilist? Yes, because, like J. L. Mackie, he was an error-theorist about morality, including the elitist morality to which he himself subscribed. But he was variously a diagnostician, an opponent and a survivor of certain other kinds of nihilism. Schacht argues that Nietzsche cannot have been an error theorist, since meta-ethical nihilism is inconsistent with the moral commitment that Nietzsche displayed. Schacht’s exegetical argument parallels the substantive argument (advocated in recent years (...) by Wright and Blackburn) that Mackie’s error theory can’t be true because if it were, we would have to give up morality or give up moralizing. I answer this argument with a little bit of help from Nietzsche. I then pose a problem, the Doppelganger Problem, for the meta-ethical nihilism that I attribute to Mackie and Nietzsche. (If A is a moral proposition then not-A is a moral proposition: hence not all moral propositions can be false.) I solve the problem by reformulating the error theory and also deal with a variant of the problem, the Reinforced Doppelganger, glancing at a famous paper of Ronald Dworkin’s. Thus, whatever its demerits, the error theory, is not self-refuting, nor does it require us to give up morality. (shrink)

For any area of our thought — moral, modal, scientihc, or theological we can ask what explains the way we think. After all, we might never have thought in such terms, or that sort of thought might have been different from the way it is. So there must be some explanation of why it is as it is. Such an explanation would be part of a naturalistic account of the mind.

Moral properties are widely held to be response‐dependent properties of actions, situations, events and persons. There is controversy as to whether the putative response‐dependence of these properties nullifies any truth‐claims for moral judgements, or rather supports them. The present paper argues that moral judgements are more profitably compared with theoretical judgements in the natural sciences than with the judgements of immediate sense‐perception. The notion of moral truth is dependent on the notion of moral knowledge, which in turn is best understood (...) as a possible endpoint of theory change for the better. (shrink)

Expressivism, as applied to a certain class of statements, evaluative ones, for instance, is constituted by two doctrines, only the first of which will concern me in this paper. Evaluative statements, according to this doctrine, aren’t propositional (susceptible of truth or falsity). In this paper, I will argue that one of the vexing problems (that I label the “logical problem”) this doctrine engenders for the expressivist is equally pressing for some cognitivists (who think evaluative statements do have a truth-value). I (...) will present the difficulty and argue that some constructivists, who are cognitivists, cannot contend with it at all, and others must resort to more complex ways than the one available to other cognitivists.

In this paper I offer solutions to two problems which our moral practice engenders for expressivism, the meta-ethical doctrine according to which ethical statements aren't propositional, susceptible of truth and falsity, but, rather, express the speaker's non-cognitive attitudes. First, the expressivist must show that arguments which are valid when interpreted propositionally are valid when construed expressivistically, and vice versa. The second difficulty is the Frege-Geach problem. Moral arguments employ atomic sentences, negations, disjunctions, etc., and, by expressivist lights, the meaning of (...) a moral sentence depends on the attitude that it expresses. Since one's attitude varies as one asserts a claim, or negates it, or cites it as a disjunct, etc., the meaning of the relevant phrase changes as well, so the argument equivocates. (Formal proofs are provided in appendices to the paper.). (shrink)

A fully developed sophisticated response-dependent account would fill in specifications for B (the beings) and C (the conditions), would probably replace the reference to disapproval with a reference to a more complex response, and might involve a more complex scheme.[ii] For simplicity, however, I shall focus my argument on the above simple scheme of moral wrongness, since added complexities will be irrelevant to my argument.

This paper presents a regress challenge to the selective psychological debunking of moral judgments. A selective psychological debunking argument conjoins an empirical claim about the psychological origins of certain moral judgments to a theoretical claim that these psychological origins cannot track moral truth, leading to the conclusion that the moral judgments are unreliable. I argue that psychological debunking arguments are vulnerable to a regress challenge, because the theoretical claim that ‘such-and-such psychological process is not moral-truth-tracking’ relies upon moral judgments. We (...) must then ask about the psychological origins of these judgments, and then make a further evaluative judgment about these psychological origins… and so on. This chain of empirical and evaluative claims may continue indefinitely and, I will argue, proponents of the debunking argument are in a dialectical position where they may not simply call a halt to the process. Hence, their argument cannot terminate, and its debunking conclusion cannot be upheld. (shrink)

Em The Sources of Normativity, Korsgaard defende que o projeto moral de Hume deve ser interpretado como naturalista e normativo. Nossa reconstrução desta interpretação propõe que Korsgaard atribui a Hume um argumento análogo ao “argumento do regresso”, que teria como consequência a tese de que, na meta-ética Humeana, a natureza humana possui valor incondicional e é a fonte de normatividade prática. Se isto estiver correto, Hume deveria ser interpretado como um naturalista redutivista sobre valor moral, reduzindo enunciados valorativos a descritivos. (...) Apresentaremos razões para resistir a esta interpretação, negando que tal “argumento do regresso” se aplique a Hume e defendendo que a sua meta-ética cumpre um papel explicativo, mas não justificatório, de nossas práticas morais.

From David Hume onwards, many philosophers have argued that moral thinking is characterized by a tendency to “project” our own mental states onto the world. This metaphor of projection may be understood as involving two empirical claims: the claim that humans experience morality as a realm of objective facts (the experiential hypothesis), and the claim that this moral experience is immediately caused by affective attitudes (the causal hypothesis). Elsewhere I argued in detail against one form of the experiential hypothesis. My (...) main aim in this paper is to show that, considering recent psychological studies about folk metaethics and the relation between moral judgements and emotions, the causal hypothesis must be considered problematic too. First, the most common argument in favor of the causal hypothesis is based on an implausible premise and a dubious assumption. Second, ordinary people’s moral experience is influenced by a non-affective factor, namely their openness to divergent moral views. And third, projectivism in general and its causal hypothesis in particular might not even hold true for affective moral judgements. This negative assessment of projectivism is significant both for our understanding of moral cognition as an empirical phenomenon and for metaethics. (shrink)

This section is a discussion of Joseph Raz's Conception of Normativity introduced by Georgios Pavlakos.

In this paper we introduce a distinct metaethical position, fictionalism about morality. We clarify and defend the position, showing that it is a way to save the 'moral phenomena' while agreeing that there is no genuine objective prescriptivity to be described by moral terms. In particular, we distinguish moral fictionalism from moral quasi-realism, and we show that fictionalism possesses the virtues of quasi-realism about morality, but avoids its vices.

This paper develops an empirical argument that the rejection of moral objectivity leaves important features of moral judgment intact. In each of five reported experiments, a number of participants endorsed a nonobjectivist claim about a canonical moral violation. In four of these experiments, participants were also given a standard measure of moral judgment, the moral/conventional task. In all four studies, participants who respond as nonobjectivists about canonical moral violations still treat such violations in typical ways on the moral/conventional task. In (...) particular, participants who give moral nonobjectivist responses still draw a clear distinction between canonical moral and conventional violations. Thus there is some reason to think that many of the central characteristics of moral judgment are preserved in the absence of a commitment to moral objectivity. (shrink)

Arguments for attributing non-conceptual content to experience have predominantly been motivated by aspects of the visual perception of empirical properties. In this article, I pursue a different strategy, arguing that a specific class of affective-evaluative experiences have non-conceptual content. The examples drawn on are affective-evaluative experiences of first exposure, in which the subject has a felt valenced intentional attitude towards evaluative properties of the object of their experience, but lacks any powers of conceptual discrimination regarding those evaluative properties. I also (...) show that by accepting this thesis we can explain relevant features of evaluative understanding. (shrink)

Simon Blackburn’s supervenience argument—focusing on the mysterious “ban on mixed worlds”—is still subject to a variety of conflicting interpretations. In this paper, I hope to provide a defense of the argument that clarifies both the argument and the objections it must overcome. Many of the extant objections, I will argue, fail to engage the argument in its true form. And to counter the more compelling objections, it will be necessary to bring in additional argumentation that Blackburn himself does not clearly (...) provide. One important upshot of this discussion is that moral realism is not the only target of the argument: it raises trouble for a variety of metaethical views wed to realist-friendly construals of moral evaluation. Rightly understood, this argument not only survives the prominent responses, but turns out to be more powerful than his critics and Blackburn himself have recognized. (shrink)

It is often said that our moral experience, broadly construed to include our ways of thinking and talking about morality, has a certain objective-seeming character to it, and that this supports a presumption in favor of objectivist theories and against anti-objectivist theories like Mackie’s error theory. In this paper, I argue that our experience of morality does not support objectivist moral theories in this way. I begin by arguing that our moral experience does not have the uniformly objective-seeming character it (...) is typically claimed to have. I go on to argue that even if moral experience were to presuppose or display morality as a realm of fact, we would still need a reason for taking that to support theories according to which it is such a realm. I consider what I take to be the four most promising ways of attempting to supply such a reason: inference to the best explanation, epistemic conservatism, the Principle of Credulity, and the method of wide reflective equilibrium. In each case, I argue, the strategy in question does not support a presumption in favor of objectivist moral theories. (shrink)

I argue against the claim that we should adopt a moral error theory. The intelligibility of our moral practice need offer no questionable metaphysical hostages to fortune. The two most credible policy recommendations that might follow from moral error theory, abolitionism and prescriptive fictionalism, are not very credible.

Response-dependent accounts of value claim that to understand what we are saying about the objects of our value judgments, we must take into account the responses those objects provoke. Recent discussions of the proposal that value is response-dependent are obscured by dogmas about response-dependence, that (1) response-dependency must be known a priori, (2) must hold necessarily, and (3) the terms involved must designate rigidly. These “dogmas” stand in the way of formulating and assessing a clear conception of value as response-dependent. (...) I point out these dogmas and argue that there is no good reason for subscribing to them. (shrink)

The possibility that nothing really matters can cause much anxiety, but what would it mean for that to be true? Since it couldn’t be bad that nothing matters, fearing nihilism makes little sense. However, the consequences of belief in nihilism will be far more dramatic than often thought. Many metaethicists assume that even if nothing matters, we should, and would, go on more or less as before. But if nihilism is true in an unqualified way, it can’t be the case (...) that we should go on as before. And given some plausible assumptions about our psychology, it’s also unlikely that we would go on as before: belief in nihilism will lead to loss of evaluative belief, and that will lead to loss or deflation of our corresponding subjective concerns. Now if nothing matters, then this consequence also wouldn’t matter. But this consequence will be extremely harmful if we believe in nihilism but things do matter, an asymmetry that gives us, in Pascalian fashion, pragmatic reasons not to believe in nihilism, and reasons not to try to find out whether it is really true.

Some philosophers object to moral error theory by arguing that there a parity between moral and epistemic normativity. They maintain that moral and epistemic error theory stand or fall together, that epistemic error theory falls, and that moral error theory thus falls too. This paper offers a response to this objection on behalf of moral error theorists. I defend the view that moral and epistemic error theory do not stand or fall together by arguing that moral error theory can be (...) sustained alongside epistemic expressivism. This unusual combination of theories can be underpinned by differences in the foundational norms that guide moral and epistemic inquiry. I conclude that the problem of epistemic normativity fails to show that it is compulsory for us to reject moral error theory. (shrink)

Moral abolitionists recommend that we get rid of moral discourse and moral judgement. At first glance this seems repugnant, but abolitionists think that we have overestimated the practical value of our moral framework and that eliminating it would be in our interests. I argue that abolitionism has a surprising amount going for it. Traditionally, abolitionism has been treated as an option available to moral error theorists. Error theorists say that moral discourse and judgement are committed to the existence of moral (...) properties, and that no such properties exist. After error theory is established, abolitionism is one potential way to proceed. However, many error theorists suggest that we retain moral discourse as a sort of fiction. I evaluate some attractions of both fictionalism and abolitionism, arguing that abolitionism is a plausible position. No one doubts that error theorists can be abolitionists. However, what has gone largely undiscussed is that it is open to others to be abolitionists as well. I argue that moral realists of a metaphysically robust sort can and perhaps should be abolitionists. ‘Realist abolitionism’ makes for a surprisingly neat theoretical package, and I conclude that it represents an interesting new option in the theoretical landscape. (shrink)

One solution to the problem of moral knowledge is to claim that we can acquire it a posteriori through moral experience. But what is a moral experience? When we examine the most compelling putative cases, we find features which, I argue, are best explained by the hypothesis that moral experiences are emotions. To preempt an objection, I argue that putative cases of emotionless moral experience can be explained away. Finally, I allay the worry that emotions are an unsuitable basis for (...) moral knowledge. I conclude that those who believe in moral experience should hold that it consists of emotion. (shrink)

Non-naturalist realists are committed to the belief, famously voiced by Parfit, that if there are no non-natural facts then nothing matters. But it is morally objectionable to conditionalise all our moral commitments on the question of whether there are non-natural facts. Non-natural facts are causally inefficacious, and so make no difference to the world of our experience. And to be a realist about such facts is to hold that they are mind-independent. It is compatible with our experiences that there are (...) no non-natural facts, or that they are very different from what we think. As Nagel says, realism makes scepticism intelligible. So the non-naturalist must hold that you might be wrong that your partner matters, even if you are correct about every natural, causal fact about your history and relationship. But to hold that conditional attitude to your partner would be a moral betrayal. So believing non-naturalist realism involves doing something immoral. (shrink)

The lesson is that while externalists avoid devastating objections to internalist moral realism, they thereby sacrifice most of thepractical significance of moral realism as an alternative to noncognitivism. They defend the objectivity of moral beliefs, but are forced to concede that the practical relevance and appeal of those beliefs depends on subjective desires. It is because they correctly reject internalism that they succumb to the non-cognitivists'tu quoque.

Moral phenomenology has enjoyed a resurgence lately, and within the field, a trend has emerged: uniform rejection of the idea that the experience of making ‘direct’ moral judgments has any phenomenal essence, that is, any phenomenal property or properties that are always present and that distinguish these experiences from experiences of making non-direct- moral judgments. This article examines existing arguments for this anti-essentialism and finds them wanting. While acknowledging that phenomenological reflection is an unstable pursuit, it is maintained here that (...) phenomenological essentialism about a certain domain of direct moral judgment, namely direct judgment of obligation and prohibition, is more credible than has been recognized. The positive proposal is to rehabilitate something close to Maurice Mandelbaum’s essentialism, specifically to maintain that direct moral judgment ’s phenomenal essence is arguably its felt categorical demand. The key to making this argument is to assume a ‘rich view’ of moral consciousness, the view that phenomenal features of moral judgment might be present even when they are not attended to. This assumption is controversial, but it is warranted by two considerations. First, though controversial, the rich view is intuitively plausible. Second, it reveals that the existing arguments against the kind of essentialism defended here appear to tacitly presuppose an equally controversial – and arguably less intuitive – rejection of the rich view.

When making moral judgments, people are typically guided by a plurality of moral rules. These rules owe their existence to human emotions but are not simply equivalent to those emotions. And people’s moral judgments ought to be guided by a plurality of emotion-based rules. The view just stated combines three positions on moral judgment: [1] moral sentimentalism, which holds that sentiments play an essential role in moral judgment,1 [2] descriptive moral pluralism, which holds that commonsense moral judgment is guided by (...) a plurality of moral rules2, and [3] prescriptive moral pluralism, which holds that moral judgment ought to be guided by a plurality of moral rules. In what follows, we will argue for all three positions. We will not present a comprehensive case for these positions nor address many of the arguments philosophers have developed against them. What we will try to show is that recent psychological work supports sentimentalist pluralism in both its descriptive and prescriptive forms. (shrink)

This paper argues that morality is objective in a specific sense that accords with a broadly expressivist stance in metaethics. The paper also explains that although there is a kind of subjectivity in moral inquiry, the same holds for other kinds of normative inquiry, including epistemic and even scientific inquiry, and moreover that this kind of subjectivity is no threat to morality’s objectivity. The argument for the objectivity of morality draws strong parallels between ethics, epistemology, and science, but does not (...) depend on equally strong parallels between ethics and mathematics. I argue that there is more to learn from a comparison between ethics and mathematics than I used to think, but the difference between the issues that come up in thinking about objectivity in ethics and those that come up in thinking about objectivity in mathematics is substantial, and we cannot carry over results from the philosophy of mathematics to the case of morality.

This paper responds to a recently popular objection to non-naturalist, robust moral realism. The objection is that moral realism is morally objectionable, because realists are committed to taking evidence about the distribution of non-natural properties to be relevant to their first-order moral commitments. I argue that such objections fail. The moral realist is indeed committed to conditionals such as “If there are no non-natural properties, then no action is wrong.” But the realist is not committed to using this conditional in (...) a modus-ponens inference upon coming to believe its antecedent. Placing the discussion in a wider epistemological discussion—here, that of “junk-knowledge”, and of how background knowledge determines the relevance of purported evidence—shows that this objection does not exert a price from the realist.

Our project in this essay is to showcase nonnaturalistic moral realism’s resources for responding to metaphysical and epistemological objections by taking the view in some new directions. The central thesis we will argue for is that there is a battery of substantive moral propositions that are also nonnaturalistic conceptual truths. We call these propositions the moral fixed points. We will argue that they must find a place in any system of moral norms that applies to beings like us, in worlds (...) similar to our own. By committing themselves to true propositions of these sorts, nonnaturalists can fashion a view that is highly attractive in its own right, and resistant to the most prominent objections that have been pressed against it.

Shaun Nichols has recently argued that while the folk notion of free will is associated with error, a question still remains whether the concept of free will should be eliminated or preserved. He maintains that like other eliminativist arguments in philosophy, arguments that free will is an illusion seem to depend on substantive assumptions about reference. According to free will eliminativists, people have deeply mistaken beliefs about free will and this entails that free will does not exist. However, an alternative (...) reaction is that free will does exist, we just have some deeply mistaken beliefs about it. According to Nichols, all such debates boil down to whether or not the erroneous folk term in question successfully refers or not. Since Nichols adopts the view that reference is systematically ambiguous, he maintains that in some contexts it’s appropriate to take a restrictivist view about whether a term embedded in a false theory refers, while in other contexts it’s appropriate to take a liberal view about whether a token of the very same term refers. This, according to Nichols, affords the possibility of saying that the sentence “free will exists” is false in some contexts and true in others. In this paper I argue that even if we grant Nichols his pluralistic approach to reference, there is still good reason to prefer eliminativism to preservationism with regard to free will. My argument focuses on one important difference between the concept of “free will” and other theoretical terms embedded in false theories—i.e., the role that the phenomenology of free agency plays in reference fixing.

The analogy between colors and values is strongly interlinked with the idea that these properties are by nature dispositions or response-dependent properties. Indeed, that colors are essentially visible, and values are inherently motivational, cries out for a dispositional or a response-dependent account. Recently, Primitivism has challenged the viability of the dispositional account of colors, taking the apple, for instance, to be “gloriously, perfectly, and primitively red.” Unsurprisingly, the attack on the dispositional account of colors has found a moral analogue in (...) the view that values are sui generis irreducibly primitive properties. The question this article addresses is whether given Primitivism the analogy between colors and values is preserved; or in other words, whether Primitivism breaks the bond between the dispositional account and the analogy between colors and values.

Either 1. the non-naturalist is in a state of mind that would treat as relevant information about the existence and patterns of non-natural properties and facts as they make up their mind about normative matters, or 2. the non-naturalist is in a state of mind that would treat as irrelevant information about the existence and patterns of non-natural properties and facts as they make up their mind about normative matters. The first state of mind is morally objectionable, for one should (...) not change one’s normative beliefs to pander to the patterns of some non-natural realm. The second state of mind is irrational, for if you think you are aiming to represent non-natural properties correctly, you should be interested to know which actions share a non-natural property and which do not, and you should be prepared to change your mind accordingly.

This paper aims to investigate Allan Gibbard’s norm-expressivist account of normativity. In particular, the aim is to see whether Gibbard’s theory is able to account for the normativity of reason-claims. For this purpose, I first describe how I come to targeting Gibbard’s theory by setting out the main tenets of quasi-realism cum expressivism. After this, I provide a detailed interpretation of the relevant parts of Gibbard’s theory. I argue that the best reading of his account is the one that takes (...) normativity to be carried by a controlled, coherent, comprehensive set of norms. Finally, I present a potential obstacle to Gibbard’s approach: the regress problem. The idea is to examine the structure of the non-cognitive state expressed and find it inadequate due to the possibility of an infinite regress in the justification of the norms whose acceptance it contains. I then end the paper with some concluding remarks. (shrink)

Creeping minimalism threatens to cloud the distinction between realist and anti-realist metaethical views. When anti-realist views equip themselves with minimalist theories of truth and other semantic notions, they are able to take on more and more of the doctrines of realism (such as the existence of moral truths, facts, and beliefs). But then they start to look suspiciously like realist views. I suggest that creeping minimalism is a problem only if moral realism is understood primarily as a semantic doctrine. I (...) argue that moral realism is better understood instead as a metaphysical doctrine. As a result, we can usefully regiment the metaethical debate into one about moral truthmakers: in virtue of what are moral judgments true? I show how the notion of truthmaking has been simmering just below the surface of the metaethical debate, and how it reveals one metaethical view (quasi-realism) to be a stronger contender than the others.

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.

Non-cognitivism is a variety of irrealism about ethics with a number of influential variants. Non-cognitivists agree with error theorists that there are no moral properties or moral facts. But rather than thinking that this makes moral statements false, noncognitivists claim that moral statements are not in the business of predicating properties or making statements which could be true or false in any substantial sense. Roughly put, noncognitivists think that moral statements have no truth conditions. Furthermore, according to non-cognitivists, when people (...) utter moral sentences they are not typically expressing states of mind which are beliefs or which are cognitive in the way that beliefs are. Rather they are expressing non-cognitive attitudes more similar to desires, approval or disapproval. Cognitivism is the denial of non-cognitivism. Thus it holds that moral statements do express beliefs and that they are apt for truth and falsity. But cognitivism need not be a species of realism since a cognitivist can be an error theorist and think all moral statements false. Still, moral realists are cognitivists insofar as they think moral statements are apt for truth and falsity and that many of them are in fact true. (shrink)

In our everyday lives, we confront a host of moral issues. Once we have deliberated and formed judgments about what is right or wrong, good or bad, these judgments tend to have a marked hold on us. Although in the end, we do not always behave as we think we ought, our moral judgments typically motivate us, at least to some degree, to act in accordance with them. When philosophers talk about moral motivation, this is the basic phenomenon they seek (...) to understand. Moral motivation is an instance of a more general phenomenon—what we might call normative motivation—for our other normative judgments also typically have some motivating force. When we make the normative judgment that something is good for us, or that we have a reason to act in a particular way, or that a specific course of action is the rational course, we also tend to be moved. Many philosophers have regarded the motivating force of normative judgments as the key feature that marks them as normative, thereby distinguishing them from the many other judgments we make. In contrast to our normative judgments, our mathematical and empirical judgments, for example, seem to have no intrinsic connection to motivation and action. The belief that an antibiotic will cure a specific infection may move an individual to take the antibiotic, if she also believes that she has the infection, and if she either desires to be cured or judges that she ought to treat the infection for her own good. All on its own, however, an empirical belief like this one appears to carry with it no particular motivational impact; a person can judge that an antibiotic will most effectively cure a specific infection without being moved one way or another.
