Book 1
3.1
The skilful teacher will make it his first care, as soon as a boy is entrusted to him, to ascertain his ability and character. The surest indication in a child is his power of memory. The characteristics of a good memory are twofold: it must be quick to take in and faithful to retain impressions of what it receives. The indication of next importance is the power of imitation: for this is a sign that the child is teachable: but he must imitate merely what he is taught, and must not, for example, mimic someone's gait or bearing or defects.
3.2
For I have no hope that a child will turn out well who loves imitation merely for the purpose of raising a laugh. He who is really gifted will also above all else be good. For the rest, I regard slowness of intellect as preferable to actual badness. But a good boy will be quite unlike the dullard and the sloth.
3.3
My ideal pupil will absorb instruction with ease and will even ask some questions; but he will follow rather than anticipate his teacher. Precocious intellects rarely produce sound fruit.
3.4
By the precocious I mean those who perform small tasks with ease and, thus emboldened, proceed to display all their little accomplishments without being asked: but their accomplishments are only of the most obvious kind: they string words together and trot them out boldly and undeterred by the slightest sense of modesty. Their actual achievement is small, but what they can do they perform with ease.
