Unhappy man, are you not content with what you see day by day? Can you set eyes on anything better or greater than the sun, the moon, the stars, the whole earth, the ocean? And if you really understand Him that governs the universe and if you carry Him about within you, do you still long for paltry stones and pretty rock? What will you do, then, when you are going to leave the very sun and moon? Shall you sit crying like little children? What were you doing, then, at school? What did you hear? What did you learn? Why did you write yourself down a philosopher when you might have written the truth, saying, 'I did a few Introductions and read Chrysippus’ sayings, but I never entered the door of a philosopher. What share have I in the calling of Socrates, who lived and died so nobly, or of Diogenes? Can you imagine one of them weeping or indignant, because he is not going to see this man or that or be in Athens or in Corinth, but in Susa, if it so chance, or Ecbatana? Does he who may leave the banquet when he will and play no longer, vex himself while he stays on? Does he not stay at play just as long as it pleases him? Do you suppose the man I describe would endure interminable exile or condemnation to death?
