One of the main objectives of a distinction of endo- and exophysics can be regarded to be the description of the self-transcendence of systems. How may this be accomplished? In the emerging subject this means the decoupling of a distinction-producing system from its environment. In this sense Reissler says: "The goal of subjectivity is to become detached from the endo-world" [1]. Figure 1 represents a concept of "naive realism", in which the outer "objective" world is appreciated as being simply "real". However, it may also be useful to demonstrate the initial stage of an endo-system before the observer, the subject, has emerged, since camera and computer alone do not represent a sphere of subjectivity (at least if some requirements, enunciated below, are not satisfied). The emergence of the subject is accompanied by the development of conceptualizations (Fig. lb). Thereby the object is constituted and the "endo-reality" vanishes.
