There are no accidents in Nature. Every motion of the constantly shifting bodies in the world is timed to the occasion for some definite, fore-ordered end. The flowers blossom in obedience to the same law that marks the course of constellations, and the song of a bird is the echo of a universal symphony. Nature is one, and to me the greatest delight of observation and study is to discover new unities in this all-embracing and eternal harmony.

Go quietly, alone; no harm will befall you. Some have strange, morbid fears as soon as they find themselves with Nature, even in the kindest and wildest of her solitudes, like very sick children afraid of their mother-as if God were dead and the devil were king.
