Pride, ill nature, and want of sense are the three great sources of ill manners; without some one of these defects, no man will behave himself ill for want of experience, or what, in the language of fools, is called knowing the world.
Jonathan SwiftBrutes find out where their talents lie; A bear will not attempt to fly, A foundered horse will oft debate Before he tries a five barred gate. A dog by instinct turns aside Who sees the ditch too deep and wide, But man we find the only creature Who, led by folly, combats nature; Who, when she loudly cries-Forbear! With obstinacy fixes there; And where the genius least inclines, Absurdly bends his whole designs.
Jonathan Swift
