Why shed tears that you must die? For if your past life has been one of enjoyment, and if all your pleasures have not passed through your mind, as through a sieve, and vanished, leaving not a rack behind, why then do you not, like a thankful guest, rise cheerfully from life's feast, and with a quiet mind go take your rest.

Poor humanity, to saddle the gods with such a responsibility and throw in a vindictive temper. What griefs they hatch for themselves, what festering sores for us, what tears for our prosperity!

True piety lies rather in the power to contemplate the universe with a quiet mind.
