It is a suggestive feature of English and other languages that an indicative sentence such as ‘Premarital sex is wrong’ can be described not only as an expression of the belief that premarital sex is wrong, but also as an expression of disapproval of premarital sex. Disapproval is plausibly regarded as an attitude that is distinct from belief, in that it does not have truth conditions. What sort of attitude, then, should we take ‘Premarital sex is wrong’ to express: disapproval, belief, or perhaps both? One group of contemporary philosophers advocates the first Option. They hold that evaluative claims serve essentially to express positive and negative attitudes that are more like desires than beliefs, and that cannot be said to be true or false — at least in the robust way in which claims about the ages of trees can be true or false. Call these philosophers ‘expressivists.’ Seemingly opposed to expressivists are those who hold that evaluative claims express beliefs, and can be true or false.
