Institutio Oratoria

Such plumpness gives hope of strength; a child fully formed in every limb is likely to grow up a puny weakling. The young should be more daring and inventive and should rejoice in their inventions, even though correctness and severity are still to be acquired. Exuberance is easily remedied, but barrenness is incurable, be your efforts what they may.

To my mind the boy who gives least promise is one in whom the critical faculty develops in advance of the imagination. I like to see the first fruits of the mind copious to excess and almost extravagant in their profusion. The years as they pass will skim off much of the froth, reason will file away many excrescences, and something too will be removed by what I may perhaps call the wear and tear of life, so long as there is sufficient material to admit of cutting and chiselling away. And there will be sufficient, if only we do not draw the plate too thin to begin with, so that it runs the risk of being broken if the graver cut too deep.

Those of my readers who know their Cicero will not be surprised

I would have the youthful mind run riot in the luxuriance of its growth

For with such a teacher their growth is stunted and their eyes are turned earthwards, and they are afraid to rise above the level of daily speech. Their leanness is regarded as a sign of health and their weakness as a sign of sound judgment, and while they are content that their work should be devoid of faults they fall into the fault of being devoid of merit. So let not the ripeness of vintage come too soon nor the must turn harsh while yet in the vat; thus it will last for years and mellow with age.

It is worth while too to warn the teacher that undue severity in correcting faults is liable at times to discourage a boy's mind from effort. He loses hope and gives way to vexation, then last of all comes to hate his work and fearing everything attempts nothing.
