This is the position and character of a layman: He never looks for either help or harm from himself, but only from externals. This is the position and character of the philosopher: He looks for all his help or harm from himself.
Signs of one who is making progress are: He censures no one, praises no one, blames no one, finds fault with no one, says nothing about himself as though he were somebody or knew something. When he is hampered or prevented, he blames himself. And if anyone compliments him, he smiles to himself at the person complimenting; while if anyone censures him, he makes no defence. He goes about like an invalid, being careful not to disturb, before it has grown firm, any part which is getting well. He has put away from himself his every desire, and has transferred his aversion to those things only, of what is under our control, which are contrary to nature. He exercises no pronounced choice in regard to anything. If he gives the appearance of being foolish or ignorant he does not care. In a word, he keeps guard against himself as though he were his own enemy lying in wait.
