Each reaching and aspiration is an instinct with which all nature consists and cรถoperates, and therefore it is not in vain. But alas! each relaxing and desperation is an instinct too. To be active, well, happy, implies courage. To be ready to fight in a duel or a battle implies desperation, or that you hold your life cheap.
Henry David ThoreauWe are double-edged blades, and every time we whet our virtue the return stroke straps our vice. Where is the skillful swordsman who can give clean wounds, and not rip up his work with the other edge?
