Cicero (on the Stoics), On Duties 1.132

Our mental operations, moreover, are of two kinds: some have to do with thought, others with impulse. Thought is occupied chiefly with the discovery of truth; impulse prompts to action. We must be careful, therefore, to employ our thoughts on themes as elevating as possible and to keep our impulses under the control of reason. The power of speech in the attainment of propriety is great, and its function is twofold: the first is oratory; the second, conversation. Oratory is the kind of discourse to be employed in pleadings in court and speeches in popular assemblies and in the senate; conversation should find its natural place in social gatherings, in informal discussions, and in intercourse with friends; it should also seek admission at dinners. There are rules for oratory laid down by rhetoricians; there are none for conversation; and yet I do not know why there should not be. But where there are students to learn, teachers are found; there are, however, none who make conversation a subject of study, whereas pupils throng about the rhetoricians everywhere. And yet the same rules that we have for words and sentences in rhetoric will apply also to conversation.
