Baltasar Gracian

"A bad manner spoils everything, even reason and justice a good one supplies everything, gilds a No, sweetens a truth, and adds a touch of beauty to old age itself."

"He that can live alone resembles the brute beast in nothing, the sage in much, and God in everything."

"Better mad with the rest of the world than wise alone."

"Never do anything when you are in a temper, for you will do everything wrong."

"Never contend with a man who has nothing to lose."

"Nature scarcely ever gives us the very best for that we must have recourse to art."
