Anaximenes regarded forensic and public oratory as genera but held that there were seven species :— exhortation, dissuasion, praise, denunciation,
I say nothing of Protagoras, who held that oratory was to be divided only into the following heads: question and answer, command and entreaty, or as he calls it εὐχωλή. Plato in his Sophist [*](222 o.) in addition to public and forensic oratory introduces a third kind which he styles προσομιλητική, which I will permit myself to translate by
conversational.This is distinct from forensic oratory and is adapted for private discussions, and we may regard it as identical with dialectic.
Isocrates [*]( Fr. 3 s. ) held that praise and blame find a place in every kind of oratory.
