So all these animals have a consciousness of their physical constitution, and for that reason can manage their limbs as readily as they do; nor have we any better proof that they come into being equipped with this knowledge than the fact that no animal is unskilled in the use of its body. But some object as follows: “According to your account, one’s constitution consists of a ruling power1044 in the soul which has a certain relation towards the body. But how can a child comprehend this intricate and subtle principle, which I can scarcely explain even to you? All living creatures should be born logicians, so as to understand a definition which is obscure to the majority of Roman citizens!” Your objection would be true if I spoke of living creatures as understanding “a definition of constitution,” and not “their actual constitution.” Nature is easier to understand than to explain; hence, the child of whom we were speaking does not understand what “constitution” is, but understands its own constitution. He does not know what “a living creature” is, but he feels that he is an animal. Moreover, that very constitution of his own he only understands confusedly, cursorily, and darkly. We also know that we possess souls, but we do not know the essence, the place, the quality, or the source, of the soul. Such as is the consciousness of our souls which we possess, ignorant as we are of their nature and position, even so all animals possess a consciousness of their own constitutions. For they must necessarily feel this, because it is the same agency by which they feel other things also; they must necessarily have a feeling of the principle which they obey and by which they are controlled. Everyone of us understands that there is something which stirs his impulses, but he does not know what it is. He knows that he has a sense of striving, although he does not know what it is or its source. Thus even children and animals have a consciousness of their primary element, but it is not very clearly outlined or portrayed.
“You maintain, do you,” says the objector, “that every living thing is at the start adapted to its constitution, but that man’s constitution is a reasoning one, and hence man is adapted to himself not merely as a living, but as a reasoning, being? For man is dear to himself in respect of that wherein he is a man. How, then, can a child, being not yet gifted with reason, adapt himself to a reasoning constitution?” But each age has its own constitution, different in the case of the child, the boy, and the old man; they are all adapted to the constitution wherein they find themselves. The child is toothless, and he is fitted to this condition. Then his teeth grow, and he is fitted to that condition also. Vegetation also, which will develop into grain and fruits, has a special constitution when young and scarcely peeping over the tops of the furrows, another when it is strengthened and stands upon a stalk which is soft but strong enough to bear its weight, and still another when the colour changes to yellow, prophesies threshing-time, and hardens in the ear—no matter what may be the constitution into which the plant comes, it keeps it, and conforms thereto. The periods of infancy, boyhood, youth, and old age, are different; but I, who have been infant, boy, and youth, am still the same. Thus, although each has at different times a different constitution, the adaptation of each to its constitution is the same. For nature does not consign boyhood or youth, or old age, to me; it consigns me to them. Therefore, the child is adapted to that constitution which is his at the present moment of childhood, not to that which will be his in youth. For even if there is in store for him any higher phase into which he must be changed, the state in which he is born is also according to nature. First of all, the living being is adapted to itself, for there must be a pattern to which all other things may be referred. I seek pleasure; for whom? For myself. I am therefore looking out for myself. I shrink from pain; on behalf of whom? Myself. Therefore, I am looking out for myself. Since I gauge all my actions with reference to my own welfare, I am looking out for myself before all else. This quality exists in all living beings—not engrafted but inborn.
Nature brings up her own offspring and does not cast them away; and because the most assured security is that which is nearest, every man has been entrusted to his own self. Therefore, as I have remarked in the course of my previous correspondence, even young animals, on issuing from
