Insane!... Ask the tyrant who is his most dangerous foe, the sane man or the insane?
Henry David ThoreauIn our most trivial walks, we are constantly, though unconsciously, steering like pilots by certain well-known beacons and headlands, and if we go beyond our usual course we still carry in our minds the bearing of some neighboring cape; and not till we are completely lost, or turned round,--for a man needs only to be turned round once with his eyes shut in this world to be lost,--do we appreciate the vastness and strangeness of nature.
Henry David Thoreau
