Epictetus,
Epictetus, the Discourses as reported by Arrian…
“ Can anyone hurt your moral purpose, or prevent you from employing in a natural way the sense-impressions which come to you?—No.—Why, then, are you any longer disturbed, and why do you want to show that you are a timid person? Why do you not come forth and make the announcement that you are at peace with all men, no matter what they do, and that you are especially amused at those who think that they are hurting you? "These slaves do not know either who I am, or where my good and my evil are; they cannot get at the things that are mine." ”
