Many philosophers, however, have been tempted to be relativists about specific domains of discourse, especially about those domains that have a normative character. Gilbert Harman, for example, has defended a relativistic view of morality, Richard Rorty a relativistic view of epistemic justification, and Crispin Wright a relativistic view of judgments of taste.¹ But what exactly is it to be a relativist about a given domain of discourse? The term ‘‘relativism’’ has, of course, been used in a bewildering variety of senses (...) and it is not my aim to discuss each and every one of those senses here. Rather, what interests me is the notion that is characterized by the following core idea: the relativist about a given domain, D, purports to have discovered that the truths of D involve an unexpected relation to a parameter.

I argue that Jonas Olson’s argument from irreducible normativity is not a secure basis for an argument for error theory and that a better basis is provided by the argument from supervenience, which has more bite against non-naturalist moral realism than Olson is willing to allow. I suggest there may be a view which can allow for the existence of irreducibly normative facts while remaining unaffected by the kinds of arguments that work against non-naturalist realism. This view is expressivism. Interestingly, (...) James Dreier has recently suggested that expressivism may not escape these arguments. I very briefly outline possible response strategies for expressivists. I close by discussing Olson’s argument against expressivism. Olson suggests, somewhat surprisingly, that expressivism is a bad fit with a plausible evolutionary explanation of our moral thought. I argue that Olson’s argument does not succeed. (shrink)

Jonas Olson writes that "a plausible moral error theory must be an error theory about all irreducible normativity". I agree. But unlike Olson, I think we cannot believe this error theory. I first argue that Olson should say that reasons for belief are irreducibly normative. I then argue that if reasons for belief are irreducibly normative, we cannot believe an error theory about all irreducible normativity. I then explain why I think Olson's objections to this argument fail. I end by (...) showing that Olson cannot defend his view as a partly revisionary alternative to an error theory about all irreducible normativity. (shrink)

According to the error theory, normative judgements are beliefs that ascribe normative properties, even though such properties do not exist. In this paper, I argue that we cannot believe the error theory, and that this means that there is no reason for us to believe this theory. It may be thought that this is a problem for the error theory, but I argue that it is not. Instead, I argue, our inability to believe the error theory undermines many objections that (...) have been made to this theory. (shrink)

Cognitivism is the view that the primary function of moral judgements is to express beliefs that purport to say how things are; expressivism is the contrasting view that their primary function is to express some desire-like state of mind. I shall consider what I call the freshman objection to expressivism. It is pretty uncontroversial that this objection rests on simple misunderstandings. There are nevertheless interesting metaethical lessons to learn from the fact that the freshman objection is prevalent among undergraduates and (...) non-philosophers. It leaves for expressivists two awkward explanatory tasks. Number one is that of explaining why natural selection – which, by expressivism's own lights, favoured moral thought and talk because of their socially useful regulative and coordinating functions – did not favour a stance that would make moral thought and talk more effective in fulfilling these functions. Number two is that of explaining how moral thought and talk survive in cultural evolution, despite the prevalence of the freshman objection and related worries. I conclude that expressivism as a theory of actual moral discourse rather than a revisionist theory is either false or committed to an implausible error theory, according to which ordinary speakers are systematically mistaken about what they are up to when they make moral judgements.

This paper advances a reductive semantics for ‘ought’ and a naturalistic theory of normativity. It gives a unified analysis of predictive, instrumental, and categorical uses of ‘ought’: the predictive ‘ought’ is basic, and is interpreted in terms of probability. Instrumental ‘oughts’ are analyzed as predictive ‘oughts’ occurring under an ‘in order that’ modifer (the end-relational theory). The theory is then extended to categorical uses of ‘ought’: it is argued that they are special rhetorical uses of the instrumental ‘ought’. Plausible conversational (...) principles explain how this end-relational ‘ought’ can perform the expressive functions of the moral ‘ought’. The notion of an ‘ought-simpliciter’ is also discussed. (shrink)

Moral contextualism is the view that claims like ‘A ought to X’ are implicitly relative to some (contextually variable) standard. This leads to a problem: what are fundamental moral claims like ‘You ought to maximize happiness’ relative to? If this claim is relative to a utilitarian standard, then its truth conditions are trivial: ‘Relative to utilitarianism, you ought to maximize happiness’. But it certainly doesn’t seem trivial that you ought to maximize happiness (utilitarianism is a highly controversial position). Some people (...) believe this problem is a reason to prefer a realist or error theoretic semantics of morals. I argue two things: first, that plausible versions of all these theories are afflicted by the problem equally, and second, that any solution available to the realist and error theorist is also available to the contextualist. So the problem of triviality does not favour noncontextualist views of moral language. (shrink)

Jonas Olson defends a moral error theory in (2014). I will first argue that Olson is not justified in believing the error theory as opposed to moral nonnaturalism in his own opinion. I will then argue that Olson is not justified in believing the error theory as opposed to moral contextualism either (although the latter is not a matter of his own opinion).

Michael Smith has recently argued that non-cognitivists are unable to accommodate crucial structural features of moral belief, and in particular that non-cognitivists have trouble accounting for subjects' certitude with respect to their moral beliefs. James Lenman and Michael Ridge have independently constructed 'ecumenical' versions of non-cognitivism, intended to block this objection. We argue that these responses do not work. If ecumenical non-cognitivism, a hybrid view which incorporates both non-cognitivist and cognitivist elements, fails to meet Smith's challenge, it is unlikely that (...) 'purer' and more familiar versions of non-cognitivism will succeed. (shrink)

Just as we can be more or less certain about empirical matters, we can be more or less certain about normative matters. Recently, it has been argued that this is a challenge for noncognitivism about normativity. Michael Smith presented the challenge in a 2002 paper and James Lenman and Michael Ridge responded independently. Andrew Sepielli has now joined the rescue operation. His basic idea is that noncognitivists should employ the notion of being for to account for normative certitude. We shall (...) argue that the being for account of normative certitude is vulnerable to many problems shared by other noncognitivist theories. Furthermore, we shall argue that Sepielli’s account has its own problems: His favored normalization procedure for degrees of being for has highly problematic implications. (shrink)

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.

In The Myth of Morality, Richard Joyce argues that moral discourse is hopelessly flawed. At the heart of ordinary moral judgements is a notion of moral inescapability, or practical authority, which, upon investigation, cannot be reasonably defended. Joyce argues that natural selection is to blame, in that it has provided us with a tendency to invest the world with values that it does not contain, and demands that it does not make. Should we therefore do away with morality, as we (...) did away with other faulty notions such as witches? Possibly not. We may be able to carry on with morality as a 'useful fiction' - allowing it to have a regulative influence on our lives and decisions, perhaps even playing a central role - while not committing ourselves to believing or asserting falsehoods, and thus not being subject to accusations of 'error'.
