By going through Białoszewski's diary and prose (including taboo areas), I indicated the difference in the revelation of sexuality by compared to the other modern writer, born almost half a century later, Adam Wiedemann. This comparative selection was dictated by similar issues regarding social conventions and the latter writer's unique autobiographical prose. Equally important was the discussion, then published in literary journals, of Adam Wiedemann's prose, the taboo of sexuality and its disclosure in recent years.
