All things are moral; and in their boundless changes have an unceasing reference to spiritual nature. Therefore is nature glorious with form, color, and motion, that every globe in the remotest heaven; every chemical change from the rudest crystal up to the laws of life; every change of vegetation from the first principle of growth in the eye of a leaf, to the tropical forest and antediluvian coal-mine; every animal function from the sponge up to Hercules, shall hint or thunder to man the laws of right and wrong, and echo the Ten Commandments.
