Be not a Quixote, ever up in arms

To give the guilty and the great alarms:

If never heeded, thy attack is vain;

And if they heed thee, they’ll attack again;

Then too in striking at that heedless rate,

Thou in an instant may’st decide thy fate.

“Leave admonition - let the vicar give

Rules how the nobles of his flock should live;

Nor take that simple fancy to thy brain,

That thou canst cure the wicked and the vain.
