The factical life of the individual… is for the most part not lived as such. Rather, it moves within a certain averageness that belongs to its caring, its going about its dealings, its circumspection, and its understanding of the world. This averageness is that of the reigning publicness at any particular time, of the social environs, the dominant trends, the “just like the others.” It is this “anyone” (Das “man” ist es) that factically lives the life of the individual. (GA62:358/n8)
This essay also identifies “this ‘anyone’” with “the nobody”: “Factical life is lived by the ‘nobody’ (Niemand)” (GA62:358/118).
