experiment, he penetrates stealthily to the most forbidden things. In the background during all his plunging and roaming--for he is as restless and aimless in his course as if lost in a wilderness--is the interrogation mark of a curiosity growing ever more dangerous. "Can we not upset every standard? and is good perhaps evil? and God only an invention and a subtlety of the devil? Is everything, in the last resort, false? And if we are dupes are we not on that very account dupers also? _must_ we not be dupers also?" Such reflections lead and mislead him, ever further on, ever further away. Solitude, that dread goddess and mater saeva cupidinum, encircles and besets him, ever more threatening, more violent, more heart breaking--but who to-day knows what solitude is? 4 From this morbid solitude, from the deserts of such trial years, the way is yet far to that great, overflowing certainty and healthiness which cannot dispense even with sickness as a means and a grappling hook of knowledge; to that matured freedom of the spirit which is, in an equal degree, self mastery and discipline of the heart, and gives access to the path of much and various reflection--to that inner comprehensiveness and self satisfaction of over-richness which precludes all danger that the spirit has gone astray even in its own path and is sitting intoxicated in some corner or other; to that overplus of plastic, healing, imitative and restorative power which is the very sign of vigorous health, that overplus which confers upon the free spirit the perilous prerogative of spending a life in experiment and of running adventurous risks: the past-master-privilege of the free spirit. In the interval there may be long years of convalescence, years filled with many hued painfully-bewitching transformations, dominated and led to the goal by a tenacious will for health that is often emboldened to assume the guise and the disguise of health. There is a middle ground to this, which a man of such destiny can not subsequently recall without emotion; he basks in a special fine sun of his own, with a feeling of birdlike freedom, birdlike visual power, birdlike irrepressibleness, a something extraneous (Drittes) in which curiosity and delicate disdain have united. A "free spirit"--this refreshing term is grateful in any mood, it almost sets one aglow. One lives--no longer in the bonds of love and hate, without a yes or no, here or there indifferently, best pleased to evade, to avoid, to beat about, neither advancing nor retreating. One is habituated to the bad, like a person who all at once sees a fearful hurly-burly _beneath_ him--and one was the counterpart of him who bothers himself with things that do not concern him. As a matter of fact the free spirit is bothered with mere things--and how many things--which no longer _concern_ him. 5
