that is the case too, not only in animals, but also in all those things which nature nourishes, causes to grow, and protects; in which we see that those things which are produced out of the earth, somehow or other by their own energy create many things for themselves which have influence on their life and growth, and so each in their own kind they arrive at the chief good. So that we may now embrace all such in one comprehensive statement; and I need not hesitate to say, that every nature is its own preserver; and has for its object, as its end and chief good, to protect itself in the best possible condition that its kind admits of; so that it follows inevitably that all things which flourish by nature have a similar but still not the same end. And from this it should be understood, that the chief and highest good to man is to live according to nature which we may interpret thus,—to live according to that nature of a man which is made perfect on all sides, and is in need of nothing. These things then we must explain; and if our explanation is rather minute, you will excuse it; for we are bound to consider the youth of our hearer, and the fact that he is now perhaps listening to such a discourse for the first time. Certainly, said I; although what you have said hitherto might be very properly addressed to hearers of any age.
X. Since then, said he, we have explained the limit of those things which are to be desired, we must next show why the facts are as I have stated them. Wherefore, let us set out from the position which I first laid down, which is also in reality the first, so that we may understand that every animal loves itself. And though there is no doubt of this, (for it is a principle fixed deep in nature itself, and is comprehended by the sense of every one, in such a degree that if any one wished to argue against it, he would not be listened to,) yet, that I may not pass over anything, I think it as well to adduce some reasons why this is the case. Although, how can any one either understand or fancy that there is any animal which hates itself? It would be a contradiction of facts; for when that appetite of the mind has begun designedly to attract anything to itself which is an hindrance to it, because it is an enemy to itself,—when it does that for its own sake, it will both hate itself and love itself, which is impossible. It is unavoidable that, if any one is an enemy to himself, he must
