1.1. Topological Structure
As is true of other models, models of temporality and change can only be conceived of with great difficulty in the absence of points of reference. In this instance, the structural and topological reference is represented by a fundamental difference on which our awareness and conception of
change depends: the difference between a sphere of stability, continuity, and identity, on the one hand, and one of variability, transformation, and dynamism, on the other hand. Change can only be perceived against a constant background just as continuity can only be recognized against the sphere of change. In an elementary form this difference between stability and continuity occurs as the boundary between the continuity of the subject having the experience and the chaotic change in that which he is experiencing in the "world." Naturally, positions providing a guarantee of identity and continuity may also develop outside the experiencing subject in the world. Thus the development of differences in temporality between different spheres and the topology of those spheres constitutes the first axis in an evolutionary-theoretical reconstruction of models of change.
