Although I have the sense that you are right that the claim of a supernatural category (as conventionally understood, as you say) is self-contradictory, I am not yet satisfied that I have it clearly in my head. So, I’d like to proceed slowly, if you’ll bear with me.
If the claim of a supernatural category entails an actual self-contradiction, then ...[text shortened]... to a reductio ad adsurdum, and should be challengeable only by challenging the premises.

I am not sure if this is what twhitehead actually meant by ‘self contradiction’ in this context but if we assume that BOTH ‘natural’ and ‘supernatural’ laws apply to everyday objects then what if some of those ‘natural laws’ actually logically contradict some of those ‘supernatural laws’?
For example, what if, according to one ‘supernatural law’, a cat CAN float past my window, but, according ‘natural law’, a cat can NOT float! Then, regardless of whether or not a cat CAN or CAN NOT float past my window, we have a logical contradiction with at least ONE of the two sets of laws -and a logical contradiction cannot exist in reality (and can only exists in our minds) -right?
