The mind is seldom quickened to very vigorous operations but by pain, or the dread of pain. We do not disturb ourselves with the detection of fallacies which do us no harm. Samuel Johnson
As an enemy is made more fierce by our flight, so Pain grows proud to see us knuckle under it. She will surrender upon much better terms to those who make head against her. Michel De Montaigne
You purchase pain with all that joy can give, and die of nothing but a rage to live. Alexander Pope
The scourge of life, and death's extreme disgrace, the smoke of hell - that monster called Pain. Philip Sidney
Nothing begins, and nothing ends, that is not paid with moan; for we are born in other's pain, and perish in our own. Francis Thompson
