Institutio Oratoria

Yes

it may be answered

but surely you do not deny that there is a type of eloquence that is too great to be comprehended by undeveloped boys?

Of course there is. But this eloquent teacher whom they fling in my face must be a sensible man with a good knowledge of teaching and must be prepared to stoop to his pupil's level, just as a rapid walker, if walking with a small child, will give him his hand and lessen his own speed and avoid advancing at a pace beyond the powers of his little companion.

Again it frequently happens that the more learned the teacher, the more lucid and intelligible is his instruction. For clearness is the first virtue of eloquence, and the less talented a man is, the more he will strive to exalt and dilate himself, just as short men tend to walk on tip-toe and weak

men to use threats.
