1080. All "movement" is thus identical to the I's connection with matter, and is thereby expressive of the functions of a "living being", its thinking and its consequent juggling with matter and the creation of the "experience of life". And we have thus arrived at purely physical sensory perception, where the "movements" are in turn divided into many different speeds and types. We know these "types of movement" as sensory impressions, as colours, as fixed, fluid, gaseous and ray-formed substances, as organisms and bodies, and so on. Since every such "movement" or type of substance is also a "limitation", it constitutes a section of space that, like the "past" and the "future", has a specific position in the range of sensory perception. But this position will not only constitute something "in front" and "behind" in the "now" itself, but also something "in front of" and "behind" other types of movement or phenomena within the range of sensory perception. And according to where they are placed they will thus be more or less to the fore in relation to the centre in this range. Thus arises the "concept of distance". Some phenomena are "near" the "central area"; others are "far away" from it. And we have here before us the primordial notion of "near" and "far", which in turn can be defined more precisely as "measurement".
