     Firstly, a word concerning ‘N.N.’. It was Nissen’s usual practice when obliterating names in the autographs of the letters (a nickname is actually involved here, as we shall see) to write above or by them ‘N.N.’, an abbreviation which can stand variously for ‘nomen nescio’, ‘nomen nominandum’, or ‘non nominato’. As used by Nissen, the abbreviation has the sense of ‘X’, as in ‘Mr. X’.⁴

     The ‘that’ stands in a relation of gradual opposition to the name: the more illegible the name, the more exposed its bearer. Not only the artist: his work still bears his name, even if it also bears another name or title. What is true of the name of the artist is true in every case of the name of the work of art, unless, of course, the name of the artist remains unknown and the name of the work is known. From the name still to be named (nomen nominandum) and the unknown name (nomen nescio) no path, only a thrust leads to the mere bearer, the bearer without a name.

     Prefaces appeared on June 17, 1844, the same day as The Concept of Anxiety. The pseudonymous author, Nicolaus Notabene, refers to himself in the text simply as N.N. These initials correspond, whether by accident or design, to the Latin phrase “nomen nescio”, or “I do not know the name”, which was a typical form of anonym.
