" Even those who have an air of being wise judge of others only, and do not know themselves. It cannot be in reason to know others and not to know oneself. Therefore one who knows himself may be said to be a man who has knowledge. Though our looks be unpleasing, we do not know it. We do not know that our skill is poor. We do not know that our station is lowly. We do not know that we grow old in years. We do not know that sickness attacks us. We do not know that death is near. We do not know that we have not attained the Way we follow. We do not know what evil is in our own persons, still less what calumny comes from without. "
