Not so extraordinary, I replied, if you bear in mind that in former days, as is commonly said, before the time of Herodicus, the guild of Asclepius did not practise our present system of medicine, which may be said to educate diseases. But Herodicus, being a trainer, and himself of a sickly constitution, by a combination of training and doctoring found out a way of torturing first and chiefly himself, and secondly the rest of the world. How was that? he said. By the invention of lingering death; for he had a mortal disease which he perpetually tended, and as recovery was out of the question, he passed his entire life as a valetudinarian; he could do nothing but attend upon himself, and he was in constant torment whenever he departed in anything from his usual regimen, and so dying hard, by the help of science he struggled on to old age. A rare reward of his skill! Yes, I said; a reward which a man might fairly expect who never understood that, if Asclepius did not instruct his descendants in valetudinarian arts, the omission arose, not from ignorance or inexperience of such a branch of medicine, but because he knew that in all well-ordered states every individual has an occupation to which he must attend, and has therefore no leisure to spend in continually being ill. This we remark in the case of the artisan, but, ludicrously enough, do not apply the same rule to people of the richer sort. How do you mean? he said. I mean this: When a carpenter is ill he asks the physician for a rough and ready cure; an emetic or a purge or a cautery or the knife,--these are his remedies. And if some one prescribes for him a course of dietetics, and tells him that he must swathe and swaddle his head, and all that sort of thing, he replies at once that he has no time to be ill, and that he sees no good in a life which is spent in nursing his disease to the neglect of his customary employment; and therefore bidding good-bye to this sort of physician, he resumes his ordinary habits, and either gets well and lives and does his business, or, if his constitution falls, he dies and has no more trouble. Yes, he said, and a man in his condition of life ought to use the art of medicine thus far only. Has he not, I said, an occupation; and what profit would there be in his life if he were deprived of his occupation? Quite true, he said. But with the rich man this is otherwise; of him we do not say that he has any specially appointed work which he must perform, if he would live. He is generally supposed to have nothing to do. Then you never heard of the saying of Phocylides, that as soon as a man has a livelihood he should practise virtue? Nay, he said, I think that he had better begin somewhat sooner.
