  There is room to object not just to the third argument, but also to the argument from design, by noting that ordered complexity can arise through mechanisms other than a guiding hand. Most of us think, for instance, that the mechanisms of natural selection result in the production of enormously complicated and yet ordered biological structures, like the human eye. If natural selection is causally responsible for the human eye, then there is no designer of these structures who efficiently caused them. We don't need power, in Reid's sense, in order to execute our plans; we just need to be the sorts of creatures whose minds are hooked up to their bodies in such a way that they do what they plan. It could be, that is, that by forming plans we engage powers that are not our own by engaging laws linking plans with execution, laws of which we are not the authors.
