Institutio Oratoria

If on the other hand not every man that speaks is an orator and primitive man did not speak like an orator, my opponents must needs acknowledge that oratory is the product of art and did not exist before it. This conclusion also rules out their argument that men speak who have never learnt how to speak, and that which a man does untaught can have no connexion with art.

In support of this contention they adduce the fact that Demades was a waterman and Aeschines an actor, but both were orators. Their reasoning is false. For no man can be an orator untaught and it would be truer to say that these orators learned oratory late in life than that they never learned at all; although as a matter of fact Aeschines had an acquaintance with literature from childhood since his father was a teacher of literature, while as regards Demades, it is quite uncertain that he never studied rhetoric and in any case continuous practice in speaking was sufficient to bring him to such proficiency as he attained: for experience is the best of all schools.

On the other hand it may fairly be asserted that he would have achieved greater distinction, if he had received instruction: for although he delivered his speeches with great effect, he never ventured to write them for others.
