Folke Tersman explores what we can learn about the nature of moral thinking by examining moral disagreement. He explains how diversity of opinion on moral issues undermines the idea that moral convictions can be objectively valued. Arguments on moral thinking are often criticized for not being able to explain why there is a contrast between ethics and other areas in which there is disagreement, but where one does not give up the idea of an objective truth, as in the natural (...) sciences. Tersman shows that the contrast has to do with facts about when, and on what basis, moral convictions can be correctly attributed to an agent or speaker. (shrink)
The fact that debunkers can turn to the argument from disagreement for help is ofcourse not a surprise. After all, both types of challenge basically pursue the same,skeptical conclusion. What I have tried to show, however, is that they are related in amore intimate way.
A recent study of moral intuitions, performed by Joshua Greene and a group of researchers at Princeton University, has recently received a lot of attention. Greene and his collaborators designed a set of experiments in which subjects were undergoing brain scanning as they were asked to respond to various practical dilemmas. They found that contemplation of some of these cases (cases where the subjects had to imagine that they must use some direct form of violence) elicited greater activity in certain (...) areas of the brain associated with emotions compared with the other cases. It has been argued (e.g., by Peter Singer) that these results undermine the reliability of our moral intuitions, and therefore provide an objection to methods of moral reasoning that presuppose that they carry an evidential weight (such as the idea of reflective equilibrium). I distinguish between two ways in which Greene's findings lend support for a sceptical attitude towards intuitions. I argue that, given the first version of the challenge, the method of reflective equilibrium can easily accommodate the findings. As for the second version of the challenge, I argue that it does not so much pose a threat specifically to the method of reflective equilibrium but to the idea that moral claims can be justified through rational argumentation in general.

Moral disagreement is sometimes thought to pose problems for moral realism because it shows that we cannot achieve knowledge of the moral facts the realists posit. In particular, it is "fundamental" moral disagreement—that is, disagreement that is not due to distorting factors such as ignorance of relevant nonmoral facts, bad reasoning skills, or the like—that is supposed to generate skeptical implications. In this paper, we show that this version of the disagreement challenge is flawed as it stands. The reason is (...) that the epistemic assumptions it requires are incompatible with the possibility of fundamental disagreement. However, we also present an alternative reconstruction of the challenge that avoids the problem. The challenge we present crucially invokes the principle that knowledge requires "adherence". While that requirement is usually not discussed in this context, we argue that it provides a promising explanation of why disagreement sometimes leads to skepticism. (shrink)
The idea of reflective equilibrium remains the most popular approach to questions about method in ethics, despite the masses of criticism it has been faced with over the years. Is this due to the availability of compelling responses to the criticisms or rather to factors that are independent of its reasonableness? The aim of this paper is to provide support for the first answer. I particularly focus on the recent discussion. Some recent objections are related to general arguments against the (...) possibility of moral knowledge, such as so-called “evolutionary debunking arguments.” I argue that nothing that has come to light in that debate, or in the recent discussion about IRE more generally, decisively strengthens the case against it. If anything, the recent developments show that IRE deserves its present status. (shrink)
A long-standing family of worries about moral realism focuses on its implications for moral epistemology. The underlying concern is that if moral truths have the nature that realists believe, it is hard to see how we could know what they are. This objection may be called the “argument from skepticism” against moral realism. Realists have primarily responded to this argument by presenting accounts of how we could acquire knowledge of moral truths that are consistent with realist assumptions about their nature. (...) Less time has been spent, however, on the question of why it would be a problem for moral realism if it leads to skepticism in the first place, and on the related question of which skeptical conclusions it would be problematic for realists to simply accept. This paper considers several answers to these questions, thereby distinguishing a number of versions of the argument from skepticism, and discusses their prospects. (shrink)
Facts about moral disagreement and human evolution have both been said to exclude the possibility of moral knowledge, but the question of how these challenges interact has largely gone unaddressed. The paper aims to present and defend a novel version of the evolutionary “debunking” argument for moral skepticism that appeals to both types of considerations. This argument has several advantages compared to more familiar versions. The standard debunking strategy is to argue that evolutionary accounts of moral beliefs generate skeptical implications (...) because they attribute those beliefs to factors that are unrelated to their truth. That strategy is vulnerable to “third-factor” responses, which invoke first-order moral claims to challenge the assumption that Darwinian factors and the moral truths are really unrelated in that way. In contrast, our version is immune to those responses, as it does not proceed via assumptions about how Darwinian factors relate to the moral facts. Instead, it focuses on what evolutionary accounts of moral beliefs have to say about the fact that people often reach divergent moral beliefs. The argument thereby illustrates how the debunking strategy can join forces with the argument from moral disagreement. The combination of those strategies presents, we think, a challenge that is more formidable than when they are considered separately. (shrink)
Crispin Wright holds that moral realism is implausible since it is not a priori that every moral disagreement involves cognitive shortcomings. I develop two responses to this argument. First, a realist may argue that it holds for at least one of the parties to any disagreement that he holds false background beliefs (moral or otherwise) or that his verdict to the disputed judgment fails to cohere with his system. Second, he may argue that if none of the verdicts involves shortcomings, (...) the appropriate conclusion is that the disagreement is not genuine, since we must otherwise attribute an inexplicable error.

Some think that recent empirical research has shown that peoples' moral intuitions vary in a way that is hard to reconcile with the supposition that they are even modestly reliable. This is in turn supposed to generate skeptical conclusions regarding the claims and theories advanced by ethicists because of the crucial role intuitions have in the arguments offered in support of those claims. I begin by trying to articulate the most compelling version of this challenge. On that version, the main (...) problem is the absence of a believable positive account of the reliability of the intuitions . I then consider the response to this challenge that, in my view, holds most promise. It differs from others by invoking substantive moral assumptions. Such a strategy may appear problematically circular, in that the justification of those assumptions seems to presuppose the very thesis that is challenged . However, although I think that objection can be met, I argue that there are other problems with the strategy. On the basis of a set of conditions that a successful defense of the pertinent kind plausibly must satisfy, I argue that the prospects of developing such an account are bleak. (shrink)
According to a traditional argument against moral realism, the existence of objective moral facts is hard to reconcile with the existence of radical disagreement over moral issues. An increasingly popular response to this argument is to insist that it generalizes too easily. Thus, it has been argued that if one rejects moral realism on the basis of disagreement then one is committed to similar views about epistemology and meta-ethics itself, since the disagreements that arise in those areas are just as (...) deep as the moral ones. This in turn is taken to show that a moral anti-realist should seek another basis for her position. For, if she extends her anti-realism also to epistemology and meta-ethics, then she is no longer in a position to say that her meta-ethical position is (objectively) true or that it is a fact that we have reason to accept it. She therefore seems left with a position that hardly even seems to be a position. The purpose of the paper is to challenge this response and in particular the claim that the argument from disagreement applies equally well to epistemology and meta-ethics as it does to ethics. It is argued that, despite contrary appearances, there are crucial differences between the disagreements that occur in ethics compared to those that arise in the other areas. Moreover, even granted that the disagreements are just as deep, there are other differences between the areas that nevertheless justify drawing different conclusions about their status from the existence of those disagreements.

A traditional objection to coherentism is that there may be incompatible though equally coherent sets of beliefs. The purpose of the paper is to assess this objection. It is argued that the better a belief "p" coheres with the system of a person, the less likely it is that the negation of the belief coheres equally well with someone else's system, or even that there is someone else who believes the negation of "p". The arguments are based on two plausible (...) assumptions about coherence, and some more controversial assumptions concerning meaning and interpretation. (shrink)
An increasingly popular strategy among critics of ethical anti-realism is to stress that the traditional arguments for that position work just as well in the case of other areas. For example, on the basis of that claim, it has recently been claimed that ethical expressivists are committed to being expressivists also about epistemic judgments (including the judgment that it is rational to believe in ethical expressivism). This in turn is supposed to seriously undermine their position. The purpose of my paper (...) is to examine this challenge. I argue that, in spite of the many similarities between the discourses, there are also crucial differences and that those differences justify a mixed verdict about them. (shrink)
However, Davidson is not only skeptical towards the view that sensory stimulation provides the basis for meaning. He has also raised some doubts about the idea that such phenomena provide the basis for knowledge. For example, he rejects the idea that the acceptance of an observation sentence could somehow be justified by the stimulations that normally cause it. This in turn leads him to doubt the thesis that observation sentences have a privileged epistemological status; a thesis that is central to (...) all forms of empiricism, Quine’s included. (shrink)
W.V. Quine has expressed a fairly conventional form of non-cognitivism in those of his writings that concern the status of moral judgments. For instance, in Quine (1981), he argues that ethics, as compared with science, is ‘methodologically infirm’. The reason is that while science is responsive to observation, and therefore ‘retains some title to a correspondence theory of truth’ (p. 63), ethics lacks such responsiveness. This in turn leads Quine to contrast moral judgments with judgments that make cognitive claims (i.e., (...) judgments that are true or false). In Quine (1986), he argues that ‘[m]oral judgments differ [...] from cognitive ones in their relation to observation’ (p. 664). (shrink)
This is acknowledged by moral realists and non-cognitivists alike, but, for obvious reasons, they relate differently to this resemblance. For realists, it provides arguments, and for non-cognitivists, it provides potential trouble. Realists claim that the various points of resemblance between moral and factual discourse indicate that moral discourse simply is a kind of factual discourse.1 However, in recent years a number of interesting attempts have been made in trying to show that the realist appearance of moral discourse can after all (...) be accommodated within a noncognitivist view.
