We are more speedily and fatally corrupted by domestic examples of vice, and particularly when they are impressed on our minds as from authority.
HoraceThe 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.
Horace
