To A certain rhetorician who was going up to Rome on A suit.—­When a certain person came to him, who was going up to Rome on account of a suit which had regard to his rank, Epictetus inquired the reason of his going to Rome, and the man then asked what he thought about the matter.  Epictetus replied:  If you ask me what you will do in Rome, whether you will succeed or fail, I have no rule ([Greek:  theoraema]) about this.  But if you ask me how you will fare, I can tell you:  if you have right opinions ([Greek:  dogmata]), you will fare well; if they are false, you will fare ill.  For to every man the cause of his acting is opinion.  For what is the reason why you desired to be elected governor of the Cnossians?  Your opinion.  What is the reason that you are now going up to Rome?  Your opinion.  And going in winter, and with danger and expense?  I must go.  What tells you this?  Your opinion.  Then if opinions are the causes of all actions, and a man has bad opinions, such as the cause may be, such also is the effect!  Have we then all sound opinions, both you and your adversary?  And how do you differ?  But have you sounder opinions than your adversary?  Why?  You think so.  And so does he think that his opinions are better; and so do madmen.  This is a bad criterion.  But show to me that you have made some inquiry into your opinions and have taken some pains about them.  And as now you are sailing to Rome in order to become governor of the Cnossians, and you are not content to stay at home with the honors which you had, but you desire something greater and more conspicuous, so when did you ever make a voyage for the purpose of examining your own opinions, and casting them out, if you have any that are bad?  Whom have you approached for this purpose?  What time have you fixed for it?  What age?  Go over the times of your life by yourself, if you are ashamed of me (knowing the fact) when you were a boy, did you examine your own opinions? and did you not then, as you do all things now, do as you did do? and when you were become a youth and attended the rhetoricians, and yourself practised rhetoric, what did you imagine that you were deficient in?  And when you were a young man and engaged in public matters, and pleaded causes yourself, and were gaining reputation, who then seemed your equal?  And when would you have submitted to any man examining and showing that your opinions are bad?  What then do you wish me to say to you?  Help me in this matter.  I have no theorem (rule) for this.  Nor have you, if you came to me for this purpose, come to me as a philosopher, but as to a seller of vegetables or a shoemaker.  For what purpose then have philosophers theorems?  For this purpose, that whatever may happen, our ruling faculty may be and continue to be conformable to nature.  Does this seem to you a small thing?  No; but the greatest.  What then? does it need only a short time? and is it possible to seize it as you pass by?  If you can, seize it.
