Once in his early youth a man allowed himself to be so far carried away in an overwrought irresponsible state as to visit a prostitute. It is all forgotten. Now he wants to get married. Then anxiety stirs. He is tortured day and night with the thought that he might possibly be a father, that somewhere in the world there could be a created being who owed his life to him. He cannot share his secret with anyone; he does not even have any reliable knowledge of the fact. –For this reason the incident must have involved a prostitute and taken place in the wantonness of youth; had it been a little infatuated or an actual seduction, it would be hard to imagine that he could know nothing about it, but now this this very ignorance is the basis of his agitated torment. On the other hand, precisely because of the rashness of the whole affair, his misgivings do not really start until he actually falls in love.
