The Education of Children (12)

This also I assert, that children ought to be led to honourable practices by means of encouragement and reasoning, and most certainly not by blows or ill-treatment, for it surely is agreed that these are fitting rather for slaves than for the freeborn; for so they grow numb and shudder at their tasks, partly from the pain of the blows, partly from the degradation. Praise and reproof are more helpful for the free-born than any sort of ill-usage, since the praise incites them toward what is honourable, and reproof keeps them from what is disgraceful.

But rebukes and praise should be used alternately and in a variety of ways; it is well to choose some time when the children are full of confidence to put them to shame by rebuke, and then in turn to cheer them up by praises, and to imitate the nurses, who, when they have made their babies cry, in turn offer them the breast for comfort. Moreover in praising them it is essential not to excite and puff them up, for they are made conceited and spoiled by excess of praise.
