ABSTRACT

This chapter introduces and tentatively defends the assumption that disagreement is a psychological phenomenon. A distinction has to do with the relata of the disagreement-relation, the objects which disagreement is a relation between. The chapter discusses what the attitudes of two individuals have to be like in order for them to disagree. However, one does not have to be an expressivist in order to reject Conflicting Beliefs and think that disagreement can involve non-doxastic attitudes. The chapter describes that the disagreement as always being a matter of having conflicting attitudes, with "attitudes" still being used in a broad sense that includes belief. The idea is that it is impossible for a single individual to rationally and coherently have both attitudes at the same time. The choice is between Rationality and Satisfaction, then it might be better not to choose.
