"If we abandon fidelity, for which we are formed, and make designs against our neighbour's wife, what are we doing?
What else but destroying and overthrowing? Whom? The man of fidelity, the man of modesty, the man of sanctity. Is this all? And are we not overthrowing neighbourhood, and friendship, and the community; and in what place are we putting ourselves? How shall I consider you? As a neighbour, as a friend? What kind? As a citizen? How can I trust you? If you were a utensil, you would be so worthless that no man could use you, and you would be thrown out on the dung heaps, and no man would pick you up. But, being a man, you are unable to fulfill any role which befits a man, what are we to do with you? Since you cannot hold the place of a friend, can you hold the place of a slave? Who will trust you? Is it not reasonable that you too should be pitched somewhere on a dung heap, as a useless utensil, and a bit of dung? But then you complain, "Doesn't anyone care about me"? They do not, because you are bad and useless. It is as if wasps complained that no man cares for them; if a man can, he strikes them and knocks them down. You have such a sting that you throw into trouble and pain any man that you wound with it. What would you have us do with you? You have no place where you can be put.
Epictetus, Discourses, Book 2, Chapter 4 (with minor alterations to, hopefully, make the language a little less stuffy without changing the meaning)
Epictetus was a Stoic philosopher and teacher. The Discourses are dated from the very turn of the 2nd century.
