Abstract

According to a common account, grammatical mood is merely a conventional indicator of force with no semantic significance. Focusing on indicatives, interrogatives and imperatives, I advance two reasons to reject this “force treatment” of mood. First, it can be shown that the mood of a subordinate clause can have semantic significance that affects the sense of a sentence in which it is embedded—which the force treatment cannot accommodate. Second, the speech acts of asserting, asking and ordering have something in common even when they do not involve the same descriptive content, namely, the commitment that is present when one speaks seriously for oneself. The force treatment cannot accommodate the fact that when we subtract this positive force from the act, what we are left with is not bare descriptive content, but the mere expression of a proposition, question or order (as appropriate). I conclude by suggesting that the sense of a mood indicator is a function from descriptive content to a proposition, question or order.
