Why metaphors make good insults: perspectives,presupposition, and pragmatics

Metaphors are powerful communicative tools because they produce ‘framing effects’. These effects are especially palpable when the metaphor is an insult that denigrates the hearer or someone he cares about. In such cases, just comprehending the metaphor produces a kind of ‘complicity’ that cannot easily be undone by denying the speaker’s claim. Several theorists have taken this to show that metaphors are engaged in a different line of work from ordinary communication. Against this, I argue that metaphorical insults are rhetorically powerful because they combine perspectives, presupposition, and pragmatics in the service of speech acts with assertoric force.
