The aim of the poet is to inform or delight, or to combine together, in what he says, both pleasure and applicability to life. In instructing, be brief in what you say in order that your readers may grasp it quickly and retain it faithfully. Superfluous words simply spill out when the mind is already full. Fiction invented in order to please should remain close to reality.
Had the crow only fed without cawing she would have had more to eat, and much less of strife and envy to contend with. [To noise abroad our success is to invite envy and competition.]
Mingle a little folly with your wisdom; a little nonsense now and then is pleasant. [Lat., Misce stultitiam consiliis brevem: Dulce est desipere in loco.
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.
