Meditation 11.28-29
Marcus AureliusMeditationsBook 11.28
28. What a man Socrates was in his under garment only, when Xanthippe took his upper garment and went out; and what he said to the friends who were shocked and retired when they saw him in that dress.
29. In writing and reciting you will not be a master before you have been a pupil. This is much more true of living.
