Cosmophilosophical conjectures can function as thought experiments intended — not to scientifically demonstrate this of that — but to allow us to consider and feel our reality differently, at least for a few seconds, at least intuitively.
Consider the following example:
What if the very small (smaller than particles) and the very big (bigger than our observable universe) were domains of pure thought, while anything in between would be (a least partly) material? Then, matter would the tension or the difference between the infinitesimally small and the cosmologically immense, a fold between the two infinites already described by Pascal and Leibniz.
But if the two infinites are pure thought, they are in fact one and the same entity: the infinitesimally small = the cosmologically enormous = pure thought.
How can there be a tension or a difference in identity? Perhaps if there is a polarity in Thought or Spirit, which is what Hegel proposed with his dialectics.
