Do we expect too much from human reason?

[Ben Davis]

Since he appears to be trying to show that, ultimately, both theistic and atheistic positions are lacking adequate epistemological justification, I'm not sure this harms his position any.

Ultimately, you're right however since he uses his argument to address 'all atheists' when it simply cannot, and then uses dismissal as a tactic to avoid answering the question or correcting his position, it demonstrates that he's prepared to be dishonest. That provides context in which I can assess his remaining arguments. I can't take his 'search for the truth' seriously when he's prepared to stand by such erroneous generalisations.
