Timaeus
Physiology and Human Nature (89b)
Timaeus: is by no means acceptable, under any other conditions, to a man of sense, it being the medical kind of purging by means of drugs. For no diseases which do not involve great danger ought to be irritated by drugging. For in its structure every disease resembles in some sort the nature of the living creature. For, in truth, the constitution of these creatures has prescribed periods of life for the species as a whole, and each individual creature likewise has a naturally predestined term of life,

And if obligatory on him, then let us raise a further question, whether this dieting of disorders, which is an impediment to the application of the mind in carpentering and the mechanical arts, does not equally stand in the way of the sentiment of Phocylides? Of that, he replied, there can be no doubt; such excessive care of the body, when carried beyond the rules of gymnastic, is most inimical to the practice of virtue. 39 Yes, indeed, I replied, and equally incompatible with the management of a house, an army, or an office of state; and, what is most important of all, irreconcileable with any kind of study or thought or self-reflection—there is a constant suspicion that headache and giddiness are to be ascribed to philosophy, and hence all practising or making trial of virtue in the higher sense is absolutely stopped; for a man is always fancying that he is being made ill, and is in constant anxiety about the state of his body. Yes, likely enough. And therefore our politic Asclepius may be supposed to have exhibited the power of his art only to persons who, being generally of healthy constitution and habits of life, had a definite ailment; such as these he cured by purges and operations, and bade them live as usual, herein consulting the interests of the State; but bodies which disease had penetrated through and through he would not have attempted to cure by gradual processes of evacuation and infusion: he did not want to lengthen out good-for-nothing lives, or to have weak fathers begetting weaker sons;—if a man was not able to live in the ordinary way he had no business to cure him;
FROM HIPPARCHUS, IN HIS TREATISE ON TRANQUILLITY. (1)

(1) Since men live but for a very short period, if their life is compared with the whole of time, they will make a most beautiful journey as it were, if they pass through life with tranquillity. This however they will possess in the most eminent degree, if they accurately and scientifically know themselves, viz. if they know that they are mortal and of a fleshly nature, and that they have a body which is corruptible and can be easily injured, and which is exposed to every thing most grievous and severe, even to their latest breath. And in the first place, let us direct our attention to those things which happen to the body; and these are pleurisy, inflammation of the lungs, phrensy, gout, stranguary, dysentery, lethargy, epilepsy, putrid ulcers, and ten thousand other diseases.
But the diseases which happen to the soul are much greater and more dire than these. For all the iniquitous, evil, illegal, and impious conduct in the life of man, originates from the passions of the soul. For through preternatural immoderate desires many have become subject to unrestrained impulses, and have not refrained from the most unholy pleasures, arising from being connected with daughters or even mothers. Many also have been induced to destroy their fathers, and their own offspring. But what occasion is there to be prolix in narrating externally impending evils, such as excessive rain, drought, violent heat and cold; so that frequently from the anomalous state of the air, pestilence and famine are produced, and all-various calamities, and whole cities become desolate?
Since therefore many such-like calamities are impendent, we should neither be elevated by the possession of corporeal goods, which may rapidly be consumed by the incursions of a small fever, nor with what are conceived to be prosperous external circumstances, which frequently in their own nature perish more rapidly than they accede. For all these are uncertain and unstable, and are found to have their existence in many and various mutations; and no one of them is permanent, or immutable, or stable, or indivisible. Hence well considering these things, and also being persuaded, that if what is present and is imparted to us, is able to remain for the smallest portion of time, it is as much as we ought to expect; we shall then live in tranquillity and with hilarity, generously bearing whatever may befal us.
