Silence - in Debate

In Debate

Argumentative silence is the rhetorical practice of saying nothing when an opponent in a debate expects something to be said. Poorly executed, it can be offensive, like refusing to answer a direct question. However, well-timed silence can throw an opponent off and give the debater the upper hand.

An argument from silence (Latin: argumentum ex silentio) is an argument based on the assumption that someone's silence on a matter suggests (an informal fallacy) that person's ignorance of the matter. In general, ex silentio refers to the claim that the absence of something demonstrates the proof of a proposition.
