Institutio Oratoria

It is generally and not unreasonably regarded as the sign of a good teacher that he should be able to differentiate between the abilities of his respective pupils and to know their natural bent. The gifts of nature are infinite in their variety, and mind differs from mind almost as much as body from body.

This is clear from a consideration of the orators themselves, who differ in style to such an extent that no one is like another, in spite of the fact that numbers have modelled their style on that of their favorite authors.

Many again think it useful to direct their instruction to the fostering of natural advantages and to guide the talents of their pupils along the lines which they instinctively tend to follow. Just as an expert gymnast, when he enters a gymnasium full of boys, after testing body and mind in every way, is able to decide for what class of athletic contest they should be trained, even so, they say,

a teacher of oratory after careful observation of a boy's stylistic preferences, be they for terseness and polish, energy, dignity, charm, roughness, brilliance or wit, will so adapt his instructions to individual needs that each pupil will be pushed forward in the sphere for which his talents seem specially to design him;

for nature, when cultivated, goes from strength to strength, while he who runs counter to her bent is ineffective in those branches of the art for which he is less suited and weakens the talents which he seemed born to employ.
