 Causes are often taken to act deterministically in accord with the principle “same cause—same effect”. Indeed, that causes determine their effects is built into many philosophical accounts of causation, such as Hume’s regularity account. We have already seen that the demand that causes determine their effects puts pressure on the idea that paradigmatic causal claims relate a small number of localized events to one another. But even considered on its own the association between determinism and causation can be marshalled in support of an anti-causal argument.
