Institutio Oratoria

For it includes practically all the exercises of which we have been speaking and is in close touch with reality. As a result it has acquired such a vogue that many think that it is the sole training necessary to the formation of an orator, since there is no excellence in a formal speech which is not also to be found in this type of rhetorical exercise.

On the other hand the actual practice of declamation has degenerated to such an extent owing to the fault of our teachers, that it has come to be one of the chief causes of the corruption of modern oratory; such is the extravagance and ignorance of our declaimers. But it is possible to make a sound use of anything that is naturally sound.
