 We begin by clarifying our question. An explanation puts an explanandum into an explanatory relation with an explanans. So, first, what exactly is the explanandum in the case of our question? Second, what kind of explanatory relation is at issue? What relation between explanandum and naturalistic explanans are we looking for? There are different kinds of explanation. And third, the explanans of a naturalistic explanation would be something naturalistic, but what would count as a naturalistic explanans?
