Such was the condition of man when the morning of science dawned upon his brain, and before he had heard the sublime declaration that the universe is governed by law.

To obey is slavish; to act from a sense of obligation perceived by the reason, is noble. Ignorance worships mystery; Reason explains it: the one grovels, the other soars.
