Embodiment Of Activity
It definitely makes sense to introduce space here as a fundamental notion. And it has far reaching implications.
“Space” refers to a principal indetermination and openness: Much more is possible than appears at first sight. And things change, through permanent (inter-)activity. Linear representations of this activity soon reach their limits, since everything gets much too complex.
In this situation the notion of space may simplify a lot. It comprises, it comprehends the whole.
But it is also logically simpler, coming before any linearity — if we understand space as the embodiment of activity as such.
Particular linear (inter-)actions are manifestations of this potentiality, tracks rutted through continual repetition, dug into space, structuring it, channelling the activity.
