Discourses: Book 2 9 : 1

It is no simple task, this of fulfilling merely the profession of a man. For what is a man? A rational, mortal animal, someone says. To begin with, from what are we distinguished by the rational element? From the wild beasts. And from what else? From sheep and the like. See to it, then, that you never act like a wild beast; if you do, you will have destroyed the man in you, you have not fulfilled your profession. See to it that you never act like a sheep; if you do, the man in you is destroyed in this way also. Well, when do we act like sheep? When we act for the sake of the belly, or of our sex-organs, or at random, or in a filthy fashion, or without due consideration, to what level have we degenerated? To the level of sheep. What have we destroyed? The reason. When we act pugnaciously, and injuriously, and angrily, and rudely, to what level have we degenerated? To the level of the wild beasts. Well, the fact is that some of us are wild beasts of a larger size, while others are little animals, malignant and petty, which give us occasion to say, "Let it be a lion that devours me!" By means of all these actions the profession of a man is destroyed. For when is a complex thing preserved? When it fulfils its profession; consequently, the salvation of a complex thing is to be composed of parts that are true. When is a discrete thing preserved? When it fulfils its profession. When are flutes, a lyre, a horse, a dog preserved? What is there to be surprised at, then, if a man also is preserved in the same way and in the same way destroyed? Now deeds that correspond to his true nature strengthen and preserve each particular man; carpentry does that for the carpenter, grammatical studies for the grammarian. But if a man acquires the habit of writing ungrammatically, his art must necessarily be destroyed and perish. So modest acts preserve the modest man, whereas immodest acts destroy him; and faithful acts preserve the faithful man while acts of the opposite character destroy him. And again, acts of the opposite character strengthen men of the opposite character; shamelessness strengthens the shameless man, faithlessness the faithless, abuse the abusive, wrath the wrathful, a disproportion between what he receives and what he pays out the miserly.
