1 Human beings have a natural tendency to form beliefs about the divine.
2 Natural human cognitive abilities are reliable or radically unreliable.
3 If reliable, we can know the divine.
4 If radically unreliable, we have a defeater for any and all human beliefs.
1 Accept the legitimacy of belief in the divine.
2 Embrace total knowledge skepticism by affirming the radical unreliability of human cognitive powers.
3 Embrace an irrational ad hoc selective skepticism willfully denying only what you dislike.
To avoid radical skepticism, he must affirm some knowledge and reject other knowledge by an act of will based on irrational taste.
Neither position is reasonable.
