The same necessity therefore forced them to catch fish and devour the oxen of the Sun. Therefore not only among the Egyptian and Syrians but Greeks too, to abstain from fish was a piece of sanctity, they avoiding (as I think), a superfluous curiosity in diet, as well as being just.
To this Nestor subjoining said: But sir, of my citizens as of the Megarians in the proverb, you make no account; although you have heard me often say that our priests of Neptune (whom we call Hieromnemons) never eat fish. For Neptune himself is called the Breeder. And the race of Hellen sacrificed to Neptune as the first father, imagining, as likewise the Syrians did, that man rose from a liquid substance. And therefore they worship a fish as of the same production and breeding with themselves, in this matter being more happy in their philosophy than Anaximander; for he says that fish and men were not produced in the same substances, but that men were first produced in fishes, and, when they were grown up and able to help themselves, were thrown out, and so lived upon the land. Therefore, as the fire devours its parents, that is, the matter out of which it was first kindled, so Anaximander, asserting that fish were our common parents, condemneth our feeding on them.
QUESTION IX. WHETHER THERE CAN BE NEW DISEASES, AND HOW CAUSED. PHILO, DIOGENIANUS, PLUTARCH.
Philo the physician stoutly affirmed that the elephantiasis was a disease but lately known; since none of the ancient physicians speak one word of it, though they oftentimes enlarge upon little, frivolous and obscure trifles. And I, to confirm it, cited Athenodorus the philosopher, who in his first book of Epidemical Diseases says, that not only that disease, but also the hydrophobia or water-dread (occasioned by the biting of a mad dog), were first discovered in the time of Asclepiades. At this the whole company were amazed, thinking it very strange that such diseases should begin then, and yet as strange that they should not be taken notice of in so long a time; yet most of them leaned to this last opinion, as being most agreeable to man, not in the least daring to imagine that Nature affected novelties, or would in the body of man, as in a city, create new disturbances and tumults.
And Diogenianus added, that even the passions and diseases of the mind go on in the same old road that formerly they did; and yet the viciousness of our inclination is exceedingly prone to variety, and our mind is mistress of itself, and can, if it please, easily change and alter. Yet all her inordinate motions have some sort of order, and the soul hath bounds to her passions, as the sea to her overflowings. And there is no sort of vice now among us which was not practised by the ancients. There are a thousand differences of appetites and various motions of fear; the schemes of grief and pleasure are innumerable.
Yet are not they of late or now produced,
And none can tell from whence they first arose.
(Sophocles, "Antigone," 456.)
How then should the body be subject to new diseases, since it hath not, like the soul, the principle of its own alteration in itself, but by common causes is joined to Nature, and receives a temperature whose infinite variety of alterations is confined to certain bounds, like a ship moving and tossing in a circle about its anchor. Now there can be no disease without some cause, it being against the laws of Nature that anything should be without a cause. Now it will be very hard to find a new cause, unless we fancy some strange air, water, or food never tasted by the ancients, should out of other worlds or intermundane spaces descend to us. For we contract diseases from those very things which preserve our life; since there are no peculiar seeds of diseases, but the disagreement of their juices to our bodies, or our excess in using them, disturbs Nature. These disturbances have still the very same differences, though now and then called by new names. For names depend on custom, but the passions on Nature; and these being constant and those variable, this error has arisen. As, in the parts of a speech and the syntax of the words, some new sort of barbarism or solecism can suddenly arise; so the temperature of the body hath certain deviations and corruptions into which it may fall, those things which are against and hurtful to Nature being in some sort existent in Nature herself. The mythographers are in this particular very ingenious, for they say that monstrous uncouth animals were produced in the time of the Giants war, the moon being out of its course, and not rising where it used to do. And those who think Nature produces new diseases like monsters, and yet give neither likely nor unlikely reasons of the change, err, as I imagine, my dear Philo, in taking a less or a greater degree of the same disease to be a different disease. The intension or increase of a thing makes it more or greater, but does not make the subject of another kind. Thus the elephantiasis, being an intense scabbiness, is not a new kind; nor is the water-dread distinguished from other melancholic and stomachical affections but only by the degree. And I wonder we did not observe that Homer was acquainted with this disease, for it is evident that he calls a dog rabid from the very same rage with which when men are possessed they are said to be mad.
Against this discourse of Diogenianus Philo himself made some objections, and desired me to be the old physicians' patron; who must be branded with inadvertency and ignorance, unless it appears that those diseases began since their time. First then Diogenianus, methinks, very precariously desires us to think that the intenseness or remissness of degrees is not a real difference, and does not alter the kind. For, were this true, then we should hold that downright vinegar is not different from pricked wine, nor a bitter from a rough taste, darnel from wheat, nor garden-mint from wild mint. For it is evident that these differences are only the several degrees of the same qualities, in some being more intense, in some more remiss. So we should not venture to affirm that flame is different from a white spirit, sunshine from flame, hoarfrost from dew, or hail from rain; but that the former have only more intense qualities than the latter. Besides, we should say that blindness is of the same kind with short-sightedness, violent vomiting (or cholera) with weakness of the stomach, and that they differ only in degree. Though what they say is nothing to the purpose; for if they allow the increase in intensity and strength, but assert that this came but now of late,—the novelty showing itself in the quantity rather than the quality,—the same difficulties which they urged against the other opinion oppress them. Sophocles says very well concerning those things which are not believed to be now, because they were not heretofore,—
Once at the first all things their being had.
And it is probable that not all diseases, as in a race, the barrier being let down, started together; but that one rising after another, at some certain time, had its beginning and showed itself. It is rational but afterwards overeating, luxury, and surfeiting, encouraged by ease and plenty, raised bad and superfluous juices, and those brought various new diseases, and their perpetual complications and mixtures still create more new. Whatever is natural is determined and in order; for Nature is order, or the work of order. Disorder, like Pindar's sand, cannot be comprised by number, and that which is beside Nature is straight called indeterminate and infinite. Thus truth is simple, and but one; but falsities innumerable. The exactness of motions and harmony are definite, but the errors either in playing upon the harp, singing, or dancing, who can comprehend? Indeed Phrynichus the tragedian says of himself,
