On the Life of the Wise Man made perfect by Instruction or, on the Unwritten Law, that is to say, on Abraham (266-270)

Nor, again, is it right for a man to pride himself on his personal advantages, in which other animals are superior to him. For what man is stronger or more vigorous than a bull among domestic animals, or than a lion among wild beasts? And what man is more sharp-sighted than a falcon or an eagle? And what man is so richly endowed with the sense of hearing as that stupidest of all animals, the ass? Also what man is more accurate in his sense of smell than a hound, who huntsmen say can trace out by means of his nose animals who are lying at a distance, and can run up to them with perfect correctness, and course, though he has not seen them; for what sight is to other animals that is the sense of smell to hounds and to all the dogs which pursue game.

Moreover, the greater part of the irrational animals enjoy excellent health, and are as far as possible entirely exempt

Therefore, the only real, and true, and lasting good is trust in God, the comfort of life, the fulfillment of all good hopes, the absence of all evils, and the attendant source of blessings, the repudiation of all unhappiness, the recognition of piety, the inheritance of all happiness, the improvement of the soul in every respect, as it thus relies for support on the cause of all things, who is able to do everything but who wills only to do what is best.

For as men who are going along a slippery road stumble and fall, but they who proceed by a dry, and level, and plain path, journey on without stumbling; so also those men who are conducting their soul through the road of bodily and external good things are only accustoming it to fall; for these things are full of stumbling and the most insecure of all. But they who by those speculations which are in accordance with virtue, hasten towards God, are guiding their souls in a safe and untroubled path. So that we may say with the most absolute truth, that the man who trusts in the good things of the body disbelieves in God, and that he who distrusts them believes in him.

But not only do the holy scriptures bear witness to the faith of Abraham in the living God, which faith is the queen of all the virtues, but moreover he is the first man whom they speak of as an elder; though there were men who had preceded him who had lived three times as many years (or even more still) as he had, not one of whom is handed down to us as worthy of the appellation. And may we not say that this is in strict accordance with natural truth? For he who is really an elder is looked upon as such, not with reference to his length of time, but to the praiseworthiness of his life.
