text: It is also said: "If honourable conduct results from precepts, then precepts are amply sufficient for the happy life; but the first of these statements is true; therefore the second is true also." We shall reply to these words that honourable conduct is, to be sure, brought about by precepts, but not by precepts alone. "Then," comes the reply, "if the other arts are content with precepts, wisdom will also be content therewith; for wisdom itself is an art of living. And yet the pilot is made by precepts which tell him thus and so to turn the tiller, set his sails, make use of a fair wind, tack, make the best of shifting and variable breezes – all in the proper manner. Other craftsmen also are drilled by precepts; hence precepts will be able to accomplish the same result in the case of our craftsman in the art of living." Now all these arts are concerned with the tools of life, but not with life as a whole. Hence there is much to clog these arts from without and to complicate them – such as hope, greed, fear. But that art which professes to teach the art of life cannot be forbidden by any circumstance from exercising its functions; for it shakes off complications and pierces through obstacles. Would you like to know how unlike its status is to the other arts? In the case of the latter, it is more pardonable to err voluntarily rather than by accident; but in the case of wisdom the worst fault is to commit sin wilfully. I mean something like this: A scholar will blush for shame, not if he makes a grammatical blunder intentionally, but if he makes it unintentionally; if a physician does not recognize that his patient is failing, he is a much poorer practitioner than if he recognizes the fact and conceals his knowledge. But in this art of living a voluntary mistake is the more shameful.
