In the mid-1950s, at the peak of psychosis, Tadeusz Peiper (the key figure in the history of Polish avantgarde) begins a gigantic manuscript-writing work, which takes the form of an all-encompassing logoreia called “Księga pamiętnikarza” [Book of Memoirist] by the author. In its present form, Book… includes dozens of folders of manuscripts and typescripts, in addition to which folders contain excerpts and newspaper clippings. By examining this – still unpublished, available only in the archive – manuscript, author of essay tries to tell the story of a creative subject at the same moment excluded from the social environment (understood as institutions, literary life, social relations) and producing a kind of phantomatic, delusional “environment” (to some extent detached from intersubjective reality).
