Heaven sends down its good and evil symbols and wise men act accordingly.

Love of goodness without love of learning degenerates into simple-mindedness. Love of knowledge without love of learning degenerates into utter lack of principle. Love of faithfulness without love of learning degenerates into injurious disregard of consequences. Love of uprightness without love of learning degenerates into harshness. Love of courage without love of learning degenerates into insubordination. Love of strong character without love of learning degenerates into mere recklessness.

There is no body but eats and drinks. But they are few who can distinguish flavors.
