 Agreement, Stevenson notes, may be dealt with “mainly by implication” (1944, 2–5). The accounts of disagreement and agreement differ in that while two persons only disagree when they have opposing beliefs or attitudes and when, moreover, at least one party to the dispute “has a motive for altering or calling into question” the belief or the attitude of the other, their agreement seems to be secured, on Stevenson’s view, simply in virtue of their having converging beliefs or attitudes (1944, 4–5). People may “neither agree nor disagree—as will happen when they are in a state of mutual indecision or irresolution,” or when they simply differ, “having divergent beliefs or attitudes without a sufficient motive for making them alike” (1944, 4–5)
