(there is) no other means of escaping from one's consciousness than to deny it, to look upon it as an organic disease of the terrestrial intelligence - a disease which we must endeavor to cure by an action which must appear to us an action of violent and willful madness, but which, on the other side of our appearances, is probably an action of health.
