Discourses, "Against or to Those Who Readily Tell Their Own Affairs" (§2)

“Something of this kind happens to us also generally. Now as this man has confidently intrusted his affairs to me, shall I also do so to any man whom I meet? (No), for when I have heard, I keep silence, if I am of such a disposition; but he goes forth and tells all men what he has heard. Then, if I hear what has been done, if I be a man like him, I resolve to be revenged, I divulge what he has told me; I both disturb others, and am disturbed myself. But if I remember that one man does not injure another, and that every man’s acts injure and profit him, I secure this, that I do not anything like him, but still I suffer what I do suffer through my own silly talk.”
