 What does the epistemic component mean for causation as lawlike regularity? The regularity is determined solely by the world, but the lawlikeness of a regularity rests, in part, on epistemic criteria. So, while causation is not arbitrary—there must still be a regularity for causation—there is an epistemic element in choosing which regularities constitute causation. In brief, the regularities are mind-independent, what causes what is not.
