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

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.

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

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.

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.

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.

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).
