It seems to me that a version of the argument from reason confirms Bayesian-confirms theism even if a naturalistic explanation of the mind is perfectly possible.
If atheism is true, how likely is it that there are creaturely minds?
P(EF)P(F) + P(EF')P(F')
E= Creaturely minds exist.
F= The fundamental causes of the universe are mental in nature.
F'= The fundamental causes of the universe are not mental in nature.
Since we are trying to determine whether the argument confirms theism, we have to assume a subject that is on the fence between F and F'. In other words we have to assume that that F = .5.
Now, how likely is it that minds should exist on the assumption that the basic causes are mental. Pretty likely, it seems to me. If theism is true, then from what we know of ourselves as rational creatures, we should expect that a rational being in charge of everything would create rational beings with whom He or She could communicate. But what if God does not exist, and the basic causes were non-mental. How there can be minds is at best difficult and at most impossible to explain. A lot of things had to happen just right in the development of the human brain in order for reason to be possible, if it is even possible at all. It looks, therefore, like the existence of creaturely minds confirms theism even if we cannot show that, for example, dualism is true. The existence of creaturely reason, therefore, confirms the mental character of the universe.
