As dialecticians we are searching for dialectical contradictions. Hegel distinguished better between different qualities than Schelling. We know, that we have to find essential contradictions for each level of matter, for each developing system. Each part of the world is in movement and contains moving parts itself. These movements can be circular.
Some ecologists think, that the universe is an eternal circular process.
Now we have to develop an new view of evolution and development, which takes into consideration these doubts. I had problems to find dialectical contradictions in each concrete realm of reality. This self-changing of conditions I could show in each concrete process with the exception of cosmically structure building after Big Bang. Nothing is isolated. Processes of all things interact with their environment.
