text: But that I, too, while engaged upon another task, may not slip into the department of the philologist or the scholar, my advice is this – that all study of philosophy and all reading should be applied to the idea of living the happy life, that we should not hunt out archaic or far-fetched words and eccentric metaphors and figures of speech, but that we should seek precepts which will help us, utterances of courage and spirit which may at once be turned into facts. We should so learn them that words may become deeds. And I hold that no man has treated mankind worse than he who has studied philosophy as if it were some marketable trade, who lives in a different manner from that which he advises. For those who are liable to every fault which they castigate advertise themselves as patterns of useless training. A teacher like that can help me no more than a sea-sick pilot can be efficient in a storm. He must hold the tiller when the waves are tossing him; he must wrestle, as it were, with the sea; he must furl his sails when the storm rages; what good is a frightened and vomiting steersman to me? And how much greater, think you, is the storm of life than that which tosses any ship! One must steer, not talk.
