"Brutes 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
