"The one who uses parrhesia, the parrhesiastes, is someone who says everything he has in mind: he does not hide anything, but opens his heart and mind completely to other people through his discourse. In parrhesia, the speaker is supposed to give a complete and exact account of what he has in mind so that the audience is able to comprehend exactly what the speaker thinks. The word "parrhesia" then, refers to a type of relationship between the speaker and what he says. For in parrhesia, the speaker makes it manifestly clear and obvious that what he says is his own opinion. And he does this by avoiding any kind of rhetorical form which would veil what he thinks. Instead, the parrhesiastes uses the most direct words and forms of expression he can find. Whereas rhetoric provides the speaker with technical devices to help him prevail upon the minds of his audience (regardless of the rhetorician's own opinion concerning what he says), in parrhesia, the parrhesiastes acts on other people's mind by showing them as directly as possible what he actually believes."
