The rhetorical situation is the context of a rhetorical event that consists of an issue, an audience, and a set of constraints. Three leading views of the rhetorical situation exist today. One argues that a situation determines and brings about rhetoric, another proposes that rhetoric creates 'situations' by making issues salient, and yet another explores the rhetor as an artist of rhetoric, creating salience through a knowledge of commonplaces.The real question in rhetorical theory is not whether the situation or the rhetor is “dominant,” but the extent, in each case, to which the rhetor can discover and control indeterminate matter, using his art of topics to make sense of what would otherwise remain simply absurd.:185 The rhetorical situation is the context of a rhetorical event that consists of an issue, an audience, and a set of constraints.

Lloyd Bitzer began the conversation in his 1968 piece titled 'The Rhetorical Situation.' Bitzer wrote that rhetorical discourse is called into existence by situation. He defined the rhetorical situation as, 'A complex of persons, events, objects, and relations presenting an actual or potential exigence which can be completely or partially removed if discourse, introduced into the situation, can so constrain human decision or action as to bring about the significant modification of the exigence.' With any rhetorical discourse, a prior rhetorical situation exists. The rhetorical situation dictates the significant physical and verbal responses as well as the sorts of observations to be made. An example of this would be a President focusing on health care policy reform because it is an apparent problem. The situation, thus, calls for the President to respond with rhetorical discourse concerning this issue. In other words, rhetorical meaning is brought about by events. Although many situations may exist, not all situations can be defined as rhetorical situations, because speech cannot rectify the problem. Bitzer especially focuses on the sense of timing (kairos) needed to speak about a situation in a way that can best remedy the exigence.
