Whereas epistemology is the philosophical theory of knowledge, its nature and scope, metaepistemology takes a step back from particular substantive debates in epistemology in order to inquire into the assumptions and commitments made by those who engage in these debates. This entry will focus on a selection of these assumptions and commitments, including whether there are objective epistemic facts; and how to characterize the subject matter and the methodology of epistemology.

Moral error theorists argue that moral thought and discourse are systematically in error, and that nothing is, or can ever be, morally permissible, required or forbidden. I begin by discussing how error theorists arrive at this conclusion. I then argue that if we accept a moral error theory, we cannot escape a pressing problem – what should we do next, metaethically speaking? I call this problem the ‘what now?’ problem, or WNP for short. I discuss the attempts others have made (...) to respond to the WNP, and in each case I show that the responses fail to be satisfying. I then propose a new response to the WNP, which I call revolutionary relativism. I define revolutionary relativism, explain why it is preferable to the existing responses to the WNP, and defend it against the most problematic objections I anticipate that opponents might raise. I conclude that revolutionary relativism succeeds where previous WNP responses fail, and that if we accept a moral error theory, we should become revolutionary relativists. (shrink)

Many philosophers have noted that normative error theorists appear to be committed to saying ‘Error theory is true, but I have no reason to believe it’, which seems paradoxical. In defence of error...

Recent literature has paid attention to a demarcation problem for evolutionary debunking arguments. This is the problem of asking in virtue of what regulative metaepistemic norm evolutionary considerations either render a belief justified, or debunk it as unjustified. I examine the so-called ‘Milvian Bridge principle’ A new science of religion, Routledge, New York, 2012; Sloan, McKenny, Eggelson Darwin in the 21st century: nature, humanity, and God, University Press, Notre Dame, 2015)), which offers exactly such a called for regulative metaepistemic norm. (...) The Milvian Bridge principle suggests that the metaepistemic norm is: adaptive reliability for truth of cognitive processes that the existence of corresponding truth-making facts evolutionary theory justifies. I argue that the Milvian Bridge principle is problematic on a number of counts, something that is shown via spiraling ‘companions in guilt arguments’. Finally, I consider ‘the core reductionist objection’ to the critique of the Milvian Bridge principle and offer a response. I conclude that the Milvian Bridge principle is destabilized. (shrink)

According to the error theory, normative judgments are beliefs that ascribe normative properties, but these properties do not exist. I have argued elsewhere (in "Can We Believe the Error Theory?") that we cannot believe this theory. Several philosophers have replied to this argument. In this chapter, I respond to their replies.

Marianna Bergamaschi Ganapini argues that we can believe the error theory. In this reply, I explain why I still think we cannot.

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.

The ‘error theory’ holds that all normative claims are false. Of course, if there is any reason to believe the error theory then, since it would be a reason to believe something, that would show the error theory itself to be false. A recent book (Streumer, 2017) tries to block this argument by arguing on the basis of the claim that the error theory itself can’t be believed that there can be no reason to believe it. This is a paradoxical (...) conclusion since it leaves the possibility that the error theory is true even though it is impossible to believe it and we can have no reason to believe it. In this paper I argue for a different paradox. Even if we can believe the error theory, we are committed to rejecting it, but this still leaves normative skepticism unanswered. (shrink)

A new kind of debate about the normative error theory has emerged. Whereas longstanding debates have fixed on the error theory’s plausibility, this new debate concerns the theory’s believability. Bart Streumer is the chief proponent of the error theory’s unbelievability. In this brief essay, we argue that Streumer’s argument prevails against extant critiques, and then press a criticism of our own.

Normative error theory is thought by some to be unbelievable because they suppose the incompatibility of believing a proposition at the same time as believing that one has no normative reason to believe it—which believing in normative error theory would seem to involve. In this article, I argue that normative holism is believable and that a normative holist will believe that the truth of a proposition does not invariably generate a normative reason to believe it. I outline five different scenarios (...) in which this is believably the case. I then show how each example can be used to generate a counterexample to the incompatibility claim. I conclude that believing a proposition is compatible with believing there is no reason to believe it and that as such normative error theory has not yet been shown to be unbelievable. (shrink)

I introduce a new version of Moral Error Theory, which I call Type-B Moral Error Theory. According to a Type-B theorist there are no facts of the kind required for there to be morality in stricto sensu, but there can be irreducible ‘normative’ properties which she deems, strictly speaking, to be morally irrelevant. She accepts that there are instrumental all things considered oughts, and categorical pro tanto oughts, but denies that there are categorical all things considered oughts on pain of (...) requiring ‘queer’ facts to obtain. I detail the most central motivation of this version of the theory against its more traditional rival, according to which there are no irreducible normative properties at all. The motivation is that it, unlike its rival, can successfully be defended against the notorious charge of self-defeat. (shrink)

We have no reason to believe that reasons do not exist. Contra Bart Streumer’s recent proposal, this has nothing to do with our incapacity to believe this error theory. Rather, it is because if we know that if a proposition is true, we have no reason to believe it, then we have no reason to believe this proposition. From a different angle: if we know that we have at best misleading reasons to believe a proposition, then we have no reason (...) to believe it. This has two consequences. Firstly, coming close to believing the error theory is idle or pointless. Secondly, philosophers who argue that believing sweeping theories like determinism or physicalism is self-defeating because they are either false or believed for no reason pursue a worthwhile argumentative strategy.

The error theory is a metaethical theory that maintains that normative judgments are beliefs that ascribe normative properties, and that these properties do not exist. In a recent paper, Bart Streumer argues that it is impossible to fully believe the error theory. Surprisingly, he claims that this is not a problem for the error theorist: even if we can’t fully believe the error theory, the good news is that we can still come close to believing the error theory. In this (...) paper I show that Streumer’s arguments fail. First, I lay out Streumer’s argument for why we can’t believe the error theory. Then, I argue against the unbelievability of the error theory. Finally, I show that Streumer’s positive proposal that we can come close to believing the error theory is actually undermined by his own argument for why we can’t believe the error theory. (shrink)
