Only the assumption that the reader - I better say: the prospective reader, because for the moment there is not the slightest prospect, that my writing could see the lights of publicity, - unless it miraculously left our endangered fortress Europe and brought a hint of the secrets of our loneliness to those outside; - I beg to be allowed to begin anew: only because I anticipate the wish to be told casually about the who and what of the writer, I send some few notes on my own individuum out before these openings, - of course not without the awareness that exactly by doing so I might provoke doubts in the reader, that he is in the right hands, which is to say: if I, from all my being, am the right man for a task to which maybe the heart pulls me more than any qualifying relation in character.
