But besides this, from a moral point of view one should close one's ears and eyes to all that is disagreeable, inharmonious, and ugly, to all that sets one against another, and one should not take notice of it. There is much beauty to be observed in our lives, if we can only turn our eyes away from all ugliness, from all that is undesirable, and fix our eyes on all that is beautiful and agreeable. For if we want to feel hurt and insulted and troubled, there is not one thing only, there are a thousand things that trouble us, and the only way of getting over them is not to notice them.
