ZEUXIPPUS. A diet which is very exact and precisely according to rule puts one’s body both in fear and danger; it hinders the gallantry of our soul itself, makes it suspicious of every thing or of having to do with any thing, no less in pleasures than in labors; so that it dares not undertake any thing boldly and courageously. We ought to do by our body as by the sail of a ship in fair and clear weather: — we must not contract it and draw it in too much, nor be too remiss or negligent about it when we have any suspicion upon us, but give it some allowance and make it pliable (as we have said), and not wait for crudities and diarrhoeas, or heat or drowsiness, by which some, as by messengers and apparitors, are frighted and moderate themselves when a fever is at hand; but we must long beforehand guard against the storm, as if the north wind blew at sea.

ZEUXIPPUS. It is absurd, as Democritus says, by the croaking of ravens, the crowing of a cock, or the wallowing of a sow in the mire, carefully to observe the signs of windy or rainy weather, and not to prevent and guard ourselves against the motions and fluctuations of our bodies or the indication of a distemper, nor to understand the signs of a storm which is just ready to break forth within ourselves. So

that we are not only to observe our bodies as to meat and exercise, whether they use them more sluggishly or unwillingly than they were wont; or whether we be more thirsty and hungry than we use to be; but we are also to take care as to our sleep, whether it be continued and easy, or whether it be irregular and convulsive. For absurd dreams and irregular and unusual fantasies show either abundance or thickness of humors, or else a disturbance of the spirits within. For the motions of the soul show that the body is nigh a distemper. For there are despondencies of mind and fears that are without reason or any apparent cause, which extinguish our hopes on a sudden. Some there are that are sharp and prone to anger, whom a little thing makes sad; and these cry and are in great trouble when ill vapors and fumes meet together and (as Plato says) are intermingled in the ways and passages of the soul. Wherefore those to whom such things happen must consider and remember, that even if there be nothing spiritual, there is some bodily cause which needs to be brought away and purged.

ZEUXIPPUS. Besides, it is profitable for him who visits his friends in their sickness to enquire after the causes of it. Let us not sophistically or impertinently discourse about lodgements, irruptions of blood, and commonplaces, merely to show our skill in the terms of art which are used in medicine. But when we have with diligence heard such trivial and common things discoursed of as fulness or emptiness, weariness, lack of sleep, and (above all) the diet which the patient kept before he fell sick, then, — as Plato used to ask himself, after the miscarriage of other men he had been with, Am not I also such a one? — so ought we to take care by our neighbor’s misfortunes, and diligently to beware that we do not fall into them, and afterwards cry out upon our sick-bed, How precious above all other things is health! When another is in sickness, let it teach us

how valuable a treasure health is, which we ought to keep and preserve with all possible care. Neither will it be amiss for every man to look into his own diet. If therefore we have been eating, drinking, laboring, or doing any thing to excess, and our bodies give us no suspicion or hint of a distemper, yet ought we nevertheless to stand upon our guard and take care of ourselves, — if it be after venery and labor, by giving of ourselves rest and quiet; if after drinking of wine and feasting, by drinking of water; but especially, after we have fed on flesh or solid meats or eaten divers things, by abstinence, that we may leave no superfluity in our bodies; for these very things, as they are the cause of many diseases, likewise administer matter and force to other causes. Wherefore it was very well said, that to eat — but not to satiety, to labor — but not to weariness, and to keep in nature, are of all things the most healthful. For intemperance in venery takes away that by which vigor our nourishment is elaborated, and causes more superfluity and redundance.

ZEUXIPPUS. But we shall begin and treat of each of these, and first we shall discourse of those exercises which are proper for a scholar. And as he that said he should prescribe nothing for the teeth to them that dwelt by the seaside taught them the benefit of the sea-water, so one would think that there was no need of writing to scholars concerning exercise. For it is wonderful what an exercise the daily use of speech is, not only as to health but even to strength. I mean not fleshly and athletic health, or such as makes one’s external parts firm, like the outside of a house, but such as gives a right tone and inward vigor to the vital and noble parts. And that the vital spirit increases strength is made plain by them who anointed the wrestlers, who commanded them, when their limbs were rubbed, to withstand such frictions in some sort, in holding their wind, observing carefully those parts of the body

which were smeared and rubbed.[*](The text of this passage is uncertain, and probably corrupt. I have given Holland’s version of the doubtful expressions. (G.)) Now the voice, being a motion of the spirit, not superficially but firmly seated in the bowels, as it were in a fountain, increases the heat, thins the blood, purges every vein, opens all the arteries, neither does it permit the coagulation or condensation of any superfluous humor, which would settle like dregs in those vessels which receive and work our nourishment. Wherefore we ought by much speaking to accustom ourselves to this exercise, and make it familiar to us; and if we suspect that our bodies are weaker or more tired than ordinary, by reading or reciting. For what riding in a coach is compared with bodily exercise, that is reading compared with disputing, if you carry your voice softly and low, as it were in the chariot of another man’s words. For disputes bring with them a vehemence and contention, adding the labor of the mind to that of the body. All passionate noise, and such as would force our lungs, ought to be avoided; for irregular and violent strains of our voice may break something within us, or bring us into convulsions. But when a student has either read or disputed, before he walks abroad, he ought to make use of a gentle and tepid friction, to open the pores of his body, as much as is possible, even to his very bowels, that so his spirits may gently and quietly diffuse themselves to the extreme parts of his body. The bounds that this friction ought not to exceed are, that it be done no longer than it is pleasant to our sense and without pain. For he that so allays the disturbance which is within himself and the agitation of his spirits will not be troubled by that superfluity which remains in him; and if it be unseasonable for to walk, or if his business hinder him, it is no great matter; for nature has already received satisfaction. Whether one be at sea or in a public inn, it is not necessary that he should be

silent, though all the company laugh at him. For where it is no shame to eat, it is certainly no shame to exercise yourself; but it is worse to stand in awe of and be troubled with seamen, carriers, and innkeepers, that laugh at you not because you play at ball or fight a shadow, but because in your discourse you exercise yourself by teaching others, or by enquiring and learning something yourself, or else by calling to mind something. For Socrates said, he that uses the exercise of dancing had need have a room big enough to hold seven beds; but he that makes either singing or discourse his exercise may do it either standing or lying in any place. But this one thing we must observe, that when we are conscious to ourselves that we are too full, or have been concerned with Venus, or labored hard, we do not too much strain our voice, as so many rhetoricians and readers in philosophy do, some of whom out of glory and ambition, some for reward or private contentions, have forced themselves beyond what has been convenient. Our Niger, when he was teaching philosophy in Galatia, by chance swallowed the bone of a fish; but a stranger coming to teach in his place, Niger, fearing he might run away with his repute, continued to read his lectures, though the bone still stuck in his throat; from whence a great and hard inflammation arising, he, being unable to undergo the pain, permitted a deep incision to be made, by which wound the bone was taken out; but the wound growing worse, and rheum falling upon it, it killed him. But this may be mentioned hereafter in its proper place.

ZEUXIPPUS. After exercise to use a cold bath is boyish, and has more ostentation in it than health; for though it may seem to harden our bodies and make them not so subject to outward accidents, yet it does more prejudice to the inward parts, by hindering transpiration, fixing the rumors, and condensing those vapors which love freedom and transpiration. Besides, necessity will force those who use cold

baths into that exact and accurate way of diet they would so much avoid, and make them take care they be not in the least extravagant, for every such error is sure to receive a bitter reproof. But a warm bath is much more pardonable, for it does not so much destroy our natural vigor and strength as it does conduce to our health, laying a soft and easy foundation for concoction, preparing those things for digestion which are not easily digested without any pain (if they be not very crude and deep lodged), and fleeing us from all inward weariness. But when we do sensibly perceive our bodies to be indifferent well, or as they ought to be, we should omit bathing, and anoint ourselves by the fire; which is better if the body stand in need of heat, for it dispenses a warmth throughout. But we should make use of the sun more or less, as the temper of the air permits. So much may suffice to have been said concerning exercises.

ZEUXIPPUS. As for what has been said of diet before, if any part of it be profitable in instructing us how we should allay and bring down our appetites, there yet remains one thing more to be advised: that if it be troublesome to treat one’s belly like one broke loose, and to contend with it though it has no ears (as Cato said), then ought we to take care that the quality of what we eat may make the quantity more light; and we should eat cautiously of such food as is solid and most nourishing (for it is hard always to refuse it), such as flesh, cheese, dried figs, and boiled eggs; but more freely of those things which are thin and light, such as moist herbs, fowl, and fish if it be not too fat; for he that eats such things as these may gratify his appetite, and yet not oppress his body. But ill digestion is chiefly to be feared after flesh, for it presently very much clogs us and leaves ill relics behind it. It would be best to accustom one’s self to eat no flesh at all, for the earth affords plenty enough of things fit not only for nourishment, but

for delight and enjoyment; some of which you may eat without much preparation, and others you may make pleasant by adding divers other things to them. But since custom is almost a second nature, we may eat flesh, but not to the cloying of our appetites, like wolves or lions, but only to lay as it were a foundation and bulwark for our nourishment, — and then come to other meats and sauces which are more agreeable to the nature of our bodies and do less dull our rational soul, which seems to be enlivened by a light and brisk diet.
