Hidden knowledge differs little from ignorance.
The poets aim is either to profit or to please, or to blend in one the delightful and the useful. Whatever the lesson you would convey, be brief, that your hearers may catch quickly what is said and faithfully retain it. Every superfluous word is spilled from the too-full memory.

When you have well thought out your subject, words will come spontaneously.
Whatever advice you give, be short.
Doctrina sed vim promovet insitam. Instruction enlarges the natural powers of the mind.
