A friend, therefore, is a sort of paradox in nature. I who alone am, I who see nothing in nature whose existence I can affirm with equal evidence to my own, behold now the semblance of my being, in all its height, variety, and curiosity, reiterated in a foreign form; so that a friend may well be reckoned the masterpiece of nature.
Ralph Waldo EmersonWe may climb into the thin and cold realm of pure geometry and lifeless science, or sink into that of sensation. Between these extremes is the equator of life, of thought, or spirit, or poetry,--a narrow belt.
Ralph Waldo Emerson
