Should my experience—the history of an illness and a convalescence, for it resulted in a convalescence—be only my personal experience? and merely just my “Human, All-too-human”? To-day I would fain believe the reverse, for I am becoming more and more confident that my books of travel were not penned for my sole benefit, as appeared for a time to be the case. May I, after six years of growing assurance, send them once more on a journey for an experiment?—May I commend them particularly to the ears and hearts of those who are afflicted with some sort of a “past,” and have enough intellect left to suffer even intellectually from their past? But above all would I commend them to you whose burden is heaviest, you choice spirits, most encompassed with perils, most intellectual, most courageous, who must be the conscience of the modern soul and as such be versed in its science:3 in whom is concentrated all of disease, poison or danger that can exist to-day: whose lot decrees that you must be more sick than any individual because you are not “mere individuals”: whose consolation it is to know and, ah! to walk the path to a new health, a health of to-morrow and the day after: you men of destiny, triumphant, conquerors of time, the healthiest and the strongest, you good Europeans!
