" Is this all the habit you acquired when you studied philosophy, to look to others and to hope for nothing from yourself and your own acts? Lament therefore and mourn, and when you eat be fearful that you will have nothing to eat to-morrow. Tremble for your wretched slaves, lest they should steal, or run away, or die. Live in this spirit, and never cease to live so, you who never came near philosophy, except in name, and disgraced its principles so far as in you lies, by showing them to be useless and unprofitable to those who take them up. "
