It is common to distinguish between disagreement in the state sense (being in disagreement) and disagreement in the activity sense (having a disagreement). This paper deals with the question of what it is for two people to have a disagreement. First, I present and reject the thesis according to which having a disagreement is a matter of expressing conflicting attitudes. I argue that this is not sufficient for having a disagreement: two people can express conflicting attitudes without having a disagreement. Second, I present and reject the thesis according to which having a disagreement involves not only the expression of conflicting attitudes, but also the persuasive attempt to bring the other around to one’s view. I argue that this is not necessary for having a disagreement: two people can have a disagreement without trying to change each other’s minds. Finally, I put forward an alternative account that goes beyond the mere expression of conflicting attitudes, but that does not go as far as to posit the attempt to change someone’s mind. Having a disagreement, I submit, is a matter of expressing conflicting attitudes and demanding agreement, that is, advancing the normative claim that the other should share one’s attitude.

Eriksson thinks that moral disagreements are intuitively faulty whereas disagreements about taste are intuitively faultless. He attempts to account for this difference by arguing, first, that moral judgements and taste judgements differ with regard to the presence of a disposition to challenge conflicting judgements and, second, that the intuition that a judgement is mistaken consists in the disposition to challenge it. In this article, I focus on the reasons given to support the first claim and argue that they are not sufficient. First, I assess the thesis that a taste judgement is only contingently connected with a disposition to challenge conflicting judgements. Second, I focus on the claim that a moral judgement is in part a disposition to challenge conflicting judgements. In both cases, I argue that the reasons given fail to disclose any substantial difference between the two domains.
