Full Idea
It might be that if causation is said to be a process, then a process is nothing more than a causal sequence, so that causation is primitive.
Gist of Idea
Causation can't be a process, because a process needs causation as a primitive

A Reaction
This again is tempting (as well as the primitivist view of probabilistic causation). If one tries to define a process as mere chronology, then the causal and accidental are indistinguishable. I take the label 'primitive' to be just our failure.
