O MORTALS, whither are you hurrying? What are you about? Why do you tumble up and down, wretches, like blind men? You are going a wrong way, and have forsaken the right. You seek prosperity and happiness in a wrong place, where it is not; nor do you give credit to another who shows you where it is. Why do you seek it without? It is not in body: if you do not believe me, look upon Myro, look upon Ofellius. It is not in wealth: if you do not believe me, look upon Croesus, look upon the rich of the present age, how full of lamentation their life is. It is not in power; for, otherwise, they who have been twice and thrice consuls must be happy, but they are not.
