It is for this reason that the famous piper Timotheus is said to have demanded from those who had previously been under another master a fee double the amount which he charged for those who came to him untaught. The mistake to which I am referring is, however, twofold. First they regard these inferior teachers as adequate for the time being and are content with their instruction because they have a stomach that will swallow anything:

this indifference, though blameworthy in itself, would yet be tolerable, if the teaching provided by these persons were merely less in quantity and not inferior in quality as well. Secondly, and this is a still commoner delusion, they think that those who are blest with greater gifts of speaking will not condescend to the more elementary details, and that consequently they sometimes disdain to give attention to such inferior subjects of study and sometimes are incapable of so doing.

For my part I regard the

teacher who is unwilling to attend to such details as being unworthy of the name of teacher: and as for the question of capacity, I maintain that it is the most capable man who, given the will, is able to do this with most efficiency. For in the first place it is a reasonable inference that a man blest with abnormal powers of eloquence will have made careful note of the various steps by which eloquence is attained, and in the second place the reasoning faculty,

which is specially developed in learned men, is all-important in teaching, while finally no one is eminent in the greater things of his art if he be lacking in the lesser. Unless indeed we are asked to believe that while Phidias modelled his Jupiter to perfection, the decorative details of the statue would have been better executed by another artist, or that an orator does not know how to speak, or a distinguished physician is incapable of treating minor ailments.

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.
