 Given the prominence of the copy-principle in Hume’s philosophical system, and its obvious relevance to the debate concerning our idea of God, it is surprising to find that in the Treatise Hume barely mentions our idea of God, much less provides any detailed account of the nature and origin of this idea. It would be a mistake, however, to conclude from this that theological problems, as they concern our idea of God, are far from his mind. On the contrary, neglecting this topic, in face of the ongoing debate and its obvious relevance for Hume’s philosophy in the Treatise, could be a way of suggesting a (strong) sceptical message.
