But the other man too, you may say, fears his master. But how is it the same thing, to have one or many, to make one timorous? Or rather, if a man inquire carefully, he will not find so much as one. How, and in what sense? Whereas that slave hath no one that desires to put him out of that service of his, and to introduce himself (whence neither hath he any one to plot against him therein); these have not even any other pursuit, but to unsettle him that is more approved and more beloved by their ruler. Wherefore also he must needs flatter all, his superiors, his equals, his friends. For where envy is, and love of glory, there even sincere friendship has no strength. For as those of the same craft cannot love one another with a perfect and genuine love, so is it with rivals in honor also, and with them that long for the same among worldly objects. Whence also great is the war within.
