Now everything is clear to me. The peculiar feeling inside is a result of that very same square situation of which I spoke in the beginning. There is no X in me. There can be none. I am simply afraid lest some X will be left in you, my unknown readers. I believe you will understand that it is harder for me to write than it ever was for any author throughout human history. Some of them wrote for contemporaries, some for the future generations but none of them ever wrote for their ancestors, or beings like their primitive, distant ancestors.
