Weissnichtwo (Know-not-where), in Carlyle's "Sartor," an imaginary European city, viewed as the focus, and as exhibiting the operation, of all the influences for good and evil of the time we live in, described in terms which characterised city life in the first quarter of the 19th century; so universal appeared the spiritual forces at work in society at that time that it was impossible to say where they were and where they were not, and hence the name of the city, Know-not-where.
