Truth contains its ultimate reason

Truth produces confidence in itself. Truth contains its ultimate reason. As a ball whose heat increases lights its own path. Few are free. Truth makes free. The man who thinks all good to consist in wealth, that is, the miser, not only mistakes, but is under the dominion, as we say, of an error... You desist at once from a thousand enforced works & words — you are free from this delusion. You are free to follow the natural constitution of your mind & the Universe.

— Ralph Waldo Emerson, journal June 15, 1831
