If you start following the parents from any concept you’ll ultimately end up going around in circles, but:
a) Further down the chain b) Counterfactuals or something very much like them (like possible worlds) are somewhere in the loop.
I think this makes a difference because if circularity is far down the chain then you can effectively ignore the circularity. Depending on other quite different concepts also makes it easier to ignore.
