Is causality transcendental?
I see a possible solution of nothing existing. There would be no causality, and also nothing to reason about. I think what is really important about the causality in reasoning, is the logic that uses it. Logic is one complicated mess. Without it, one would imagine things being both true and false, not existing and existing simultaneously; but all of this would follow a reasoning of what illogical existence would be like. A causal flow of premises to conclusion. It would work now to think about possible scenarios, but when actualized, that reasoning could never hold up. It may be false or true, or neither. It would be chaos.
