The Main Issues

TL;DR: The lack of differentiation between practice, dialectic, and theory is problematic; this lack of theory may lead to a gradual accumulation of difficulties for any research involving time and/or space, mainly in the mathematical modeling of phenomena and in philosophical conceptions of the world.

Abstract: The lack of differentiation between practice, dialectic, and theory is problematic. The question of practice concerns the way time and space are used; it seems to have developed to the detriment of the theory. Dialectic is a rigorous form of reasoning: it is what we think. But the dialectics of time and space are bogged down by practice, and suffer interference from everyday language usage. The stringent requirements of theory are no longer respected. A theory is intended to enrich and organize knowledge: it is what we know. Nevertheless time and space are not theorized: they are not defined, their nature is unknown, their properties are not identified, and their existence is not clarified. There is every reason to think that this lack of theory may lead to a gradual accumulation of difficulties for any research involving time and/or space, mainly in the mathematical modeling of phenomena and in philosophical conceptions of the world.
