“I have the courage, I believe, to doubt everything; I have the courage, I believe, to fight with everything; but I have not the courage to know anything; not the courage to possess, to own anything. Most people complain that the world is so prosaic, that life is not like romance, where opportunities are always so favorable. I complain that life is not like romance, where one had hard-hearted parents and nixies and trolls to fight, and enchanted princesses to free. What are all such enemies taken together, compared with the pale, bloodless, tenacious, nocturnal shapes with which I fight, and to whom I give life and substance?”
