There are, however, salutary things, and others hurtful? PHYSICIAN. You have guessed all the secret. Eat moderately that which you know by experience will agree with you. Nothing is good for the body but what is easily digested. What medicine will best assist digestion? Exercise. What best recruit your strength? Sleep. What will diminish incurable ills? Patience. What change a bad constitution? Nothing. In all violent maladies, we have only the recipe of Molire, "_seipnare, purgare;_" and, if we will, "_clisterium donare._" There is not a fourth. All, I have told you amounts only to keeping a house in order, to which we cannot add a peg. All art consists in adaptation. PRINCESS. You puff not your merchandise. You are an honest man. When I am queen, I will make you my first physician. PHYSICIAN. Let nature be your first physician. It is she who made all. Of those who have lived beyond a hundred years, none were of the faculty. The king of France has already buried forty of his physicians, as many chief physicians, besides physicians of the establishment, and others. PRINCESS. And, truly, I hope to bury you also. MAN. To know the natural philosophy of the human race, it is necessary to read works of anatomy, or rather to go through a course of anatomy. To be acquainted with the man we call "moral," it is above all necessary to have lived and reflected. Are not all moral works contained in these words of Job? "Man that is born of a woman hath but a few days to live, and is full of trouble. He cometh forth like a flower, and is cut down: he fleeth as a shadow, and continueth not." We have already seen that the human race has not above two-and-twenty years to live, reckoning those who die at their nurses' breasts, and those who for a hundred years drag on the remains of a miserable and imbecile life. It is a fine apologue, that ancient fable of the first man who was at first destined to live twenty years at most, and who reduced it to five years by estimating one life with another. The man was in despair, and had near him a caterpillar, a butterfly, a peacock, a horse, a fox, and an ape.
