Book I chapter 7

Passing now to the faculty¹ of Growth let us first mention that this, too, is present in the foetus in utero as is also the nutritive faculty, but that at that stage these two faculties² are, as it were, handmaids to those already mentioned, and do not possess in themselves supreme³ authority. When, however, the animal has attained⁴ its complete size, then, during the whole period following its birth and until the acme⁵ is reached, the faculty of growth is predominant, while the alterative⁶ and nutritive faculties are accessory — in fact, act as its handmaids. What, then, is the property of this faculty of growth? To extend in every direction that which has already come into existence — that is to say, the solid parts of the body, the arteries⁷, veins⁸, nerves, bones, cartilages, membranes⁹, ligaments, and the various coats which we have just called elementary, homogeneous, and simple. And I shall state in what way they gain this extension in every direction, first giving an illustration for the sake of clearness.

Children take the bladders of pigs, fill them with air, and then rub them on ashes near the fire, so as to warm, but not to injure them. This is a common game in the district of Ionia, and among not a few other nations. As they rub, they sing songs, to a certain measure, time, and rhythm, and all their words are an exhortation¹⁰ to the bladder to increase in size. When it appears to them fairly well distended¹¹, they again blow air into it and expand it further; then they rub it again. This they do several times, until the bladder seems to them to have become large enough. Now, clearly, in these doings of the children, the more the interior cavity of the bladder increases in size, the thinner, necessarily, does its substance become. But, if the children were able to bring nourishment¹² to this thin part, then they would make the bladder big in the same way that Nature does. As it is, however, they cannot do what Nature does, for to imitate this is beyond the power not only of children, but of any one soever; it is a property of Nature alone.

It will now, therefore, be clear to you that nutrition is a necessity for growing things. For if such bodies were distended, but not at the same time nourished, they would take on a false appearance of growth, not a true growth. And further, to be distended in all directions belongs only to bodies whose growth is directed by Nature; for those which are distended by us undergo this distension¹³ in one direction but grow less in the others; it is impossible to find a body which will remain entire and not be torn through whilst we stretch it in the three dimensions. Thus Nature alone has the power to expand a body in all directions so that it remains¹⁴ unruptured and preserves completely its previous form.

Such then is growth, and it cannot occur without the nutriment which flows to the part and is worked up into it.
