Pessoa invented The Book of Disquiet, which never existed, strictly speaking, and can never exist. What we have here isn't a book but its subversion and negation: the ingredients for a book whose recipe is to keep sifting, the mutant germ of a book and its weirdly lush ramifications, the rooms and windows to build a book but no floor plan and no floor, a compendium of many potential books and many others already in ruins. What we have in these pages is an anti-literature, a kind of primitive, verbal CAT scan of one man's anguished soul.
