Plutarch's Rules for the Preservation of Health (16-20)

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.[*] 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.

ZEUXIPPUS. As for liquids, we should never make milk our drink, but rather take it as food, it yielding much solid nourishment. As for wine, we must say to it what Euripides said to Venus: —

Thy joys with moderation I would have,

And that I ne’er may want them humbly crave.

For wine is the most beneficial of all drinks, the pleasantest medicine in the world, and of all dainties the least cloying to the appetite, provided more regard be given to the opportunity of the time of drinking it than even to its being properly mixed with water. Water, not only when it is mixed with wine, but also if it be drunk by itself between mixed wine and water, makes the mingled wine the less hurtful. We should accustom ourselves therefore in our daily diet to drink two or three glasses of water, which will allay the strength of the wine, and make drinking of water familiar to our body, that so in a case of necessity it may not be looked on as a stranger, and we be offended at it. It so falls out, that some have then the greatest inclination for wine when there is most need they should drink water; for such men, when they have been exposed to great heat of the sun, or have fallen into a chill, or have been speaking vehemently, or have been more than ordinarily thoughtful about any thing, or after any fatigue or labor, are of the opinion that they ought to drink wine, as if nature required some repose for the body and some diversion after its labors. But nature requires no such repose (if you will call pleasure repose), but desires only such an alteration as shall be between pleasure and pain; in which case we ought to abate of our diet, and either wholly abstain from wine, or drink it allayed with very much mixture of water. For wine, being sharp and fiery, increases the disturbances of the body, exasperates them, and wounds the parts affected; which stand more in need of being comforted and smoothed, which water does the best of any thing. If, when we are not thirsty, we drink warm water after labor, exercise, or heat, we find our inward parts loosened and smoothed by it; for the moisture of water is gentle and not violent, but that of wine carries a great force in it, which is no ways agreeable in the fore-mentioned cases. And if any one should be afraid that abstinence would bring upon the bodythat acrimony and bitterness which some say it will, he is like those children who think themselves much wronged because they may not eat just before the fit of a fever. The best mean between both these is drinking of water. We oftentimes sacrifice to Bacchus himself without wine, doing very well in accustoming ourselves not to be always desirous of wine. Minos made the pipe and the crown be laid aside at the sacrifice when there was mourning. And yet we know an afflicted mind is not at all affected by either the pipe or crown; but there is no body so strong, to which, in commotion or a fever, wine does not do a great deal of injury.

ZEUXIPPUS. The Lydians are reported in a famine to have spent one day in eating, and the next in sports and drollery. But a lover of learning and a friend to the Muses, when at any time he is forced to sup later than ordinary, will not be so much a slave to his belly as to lay aside a geographical scheme when it is before him, or his book, or his lyre; but strenuously turning himself, and taking his mind off from eating, he will in the Muses’ name drive away all such desires, as so many Harpies, from his table. Will not the Scythian in the midst ’of his cups oftentimes handle his bow and twang the string, thereby rousing up himself from that drunkenness in which he was immersed? Will a Greek be afraid, because he is laughed at, by books and letters gently to loosen and unbend any blind and obstinate desire? The young men in Menander, when they were drinking, were trepanned by a bawd, which brought in to them a company of handsome and richly attired women; but every one, as he said,

Cast down his eyes and fell to junketing, —

not one daring to look upon them. Lovers of learning have many fair and pleasant diversions, if they can no other way keep in their canine and brutish appetites when they see the table spread. The bawling of such fellows as anoint wrestlers, and the opinion of pedagogues that it hinders our nourishment and dulls one’s head to discourse of learning at table, are indeed of some force then, when we are called upon to solve a fallacy like the Indus or to dispute about the Kyrieuon at a feast. For though the pith of the palm-tree is very sweet, yet they say it will cause the headache. To discourse of logic at meals is not indeed a very delicious banquet, is rather troublesome, and pains one’s head; but if there be any who will not give us leave to discourse philosophically or ask any question or read any thing at table, though it be of those things which are not only decent and profitable but also pleasantly merry, we will desire them not to trouble us, but to talk in this style to the athletes in the Xvstum and the Palaestra, who have laid aside their books and are wont to spend their whole time in jeers and scurrilous jests, being, as Aristo wittily expresses it, smooth and hard, like the pillars in the gymnasium. But we must obey our physicians, who advise us to keep some interval between supper and sleep, and not to heap up together a great deal of victuals in our stomachs and so shorten our breath (lest we presently by crude and fermenting aliment overcharge our digestion), but rather to take some space and breathing-time before we sleep. As those who have a mind to exercise themselves after supper do not do it by running or wrestling, but rather by gentle exercise, such as walking or dancing; so when we intend to exercise our minds after supper, we are not to do it with any thing of business or care, or with those sophistical disputes which bring us into a vain-glorious and violent contention. But there are many questions in natural philosophy which are easy to discuss and to decide; there are many disquisitions which relate to manners, which please the mind (as Homer expresses it) and do no way discompose it. Questions in history and poetry have been by some ingeniously called a second course to a learned man and a scholar. There are discourses which are no way troublesome; and, besides, fables may be told. Nay, it is easier to discourse of the pipe and lyre, or hear them discoursed of, than it is to hear either of them played on. The quantity of time allowed for this exercise is till our meat be gently settled within us, so that our digestion may have power enough to master it.
