“Unfamiliar environments heighten adrenalin, which might work for stimulating excitement or against totally relaxing into any kind of intimacy.”

Context: Once, when hitchhiking, I was picked up by a professor from some small college. He noticed a book in my coat pocket, and was curious. It was a Modern Library edition, in the limp bindings they used to have, which sold at the time for 95 cents. This one contained Nietzsche‎‎'s Ecce Homo, and The Birth of Tragedy.
The professor was a pedantic man of limited imagination and seemed almost offended that I was reading such a book. Obviously I did not fit some category in which he decided I belonged, and when he dropped me off in town, I suspect he was relived to be rid of me.
He kept asking me why I wanted to read such a book. At first, he doubted I was reading it. Where had I heard of Nietzsche‎‎?
When I told him I thought it was in the preface to a book on Schopenhauer, he was even more disturbed and probably believed I was lying. Fortunately, there seem to be few of his kind, and my subsequent friendships with university professors have proved exciting, stimulating and fun.

Context: Even when I was a fairly precocious young man the nothingness of the hopes and strivings which chases most men restlessly through life came to my consciousness with considerable vitality. Moreover, I soon discovered the cruelty of that chase, which in those years was much more carefully covered up by hypocrisy and glittering words than is the case today. By the mere existence of his stomach everyone was condemned to participate in that chase. Moreover, it was possible to satisfy the stomach by such participation, but not man in so far as he is a thinking and feeling being. As the first way out there was religion, which is implanted into every child by way of the traditional education-machine. Thus I came—despite the fact that I was the son of entirely irreligious (Jewish) parents—to a deep religiosity, which, however, found an abrupt ending at the age of 12. Through the reading of popular scientific books I soon reached the conviction that much in the stories of the Bible could not be true. The consequence was a positively fanatic [orgy of] freethinking coupled with the impression that youth is intentionally being deceived by the state through lies; it was a crushing impression. Suspicion against every kind of authority grew out of this experience, a skeptical attitude towards the convictions which were alive in any specific social environment—an attitude which has never again left me, even though later on, because of a better insight into the causal connections, it lost some of its original poignancy.
