I am well aware that there are certain writers who would absolutely bar all study of artistic structure and contend that language as it chances to present itself in the rough is more natural and even more manly. If by this they mean that only that is natural which originated with nature and has never received any subsequent cultivation, there is an end to the whole art of oratory.

For the first men did not speak with the care demanded by that art nor in accordance with the rules that it lays down. They knew nothing of introducing their case by means of an exordium, of instructing the jury by a statement of facts, of proving by argument or of arousing the emotions. They lacked all these qualifications as completely as they lacked all knowledge of the theory of artistic structure. But if they were to be forbidden all progress in this respect, they ought equally to have been forbidden to exchange their huts for houses, their cloaks of skin for civilised raiment and their mountains and forests for cities.
