Strawson, Galen - The Secret Connexion: Causation, Realism, and David Hume

One response to the claim that Hume believes in causal power is that it is obviously true and completely uncontroversial. 'Of course he does. The fact that he does is a principal consequence of his central doctrine of "natural belief"¹ --his doctrine about the sorts of things we can't help believing in "common" or everyday life, irrespective of our philosophical conclusions. He has no doubt that we can't help believing in causal power, just as we can't help believing in truly external physical objects.'
