Gutting states:
Religious believers often accuse argumentative atheists such as Dawkins of being excessively rationalistic, demanding standards of logical and evidential rigor that aren't appropriate in matters of faith. My criticism is just the opposite. Dawkins does not meet the standards of rationality that a topic as important as religion requires.
The basic problem is that meeting such standards requires coming to terms with the best available analyses and arguments. This need not mean being capable of contributing to the cutting-edge discussions of contemporary philosophers, but it does require following these discussions and applying them to one's own intellectual problems. Dawkins simply does not do this. He rightly criticizes religious critics of evolution for not being adequately informed about the science they are calling into question. But the same criticism applies to his own treatment of philosophical issues.
There are sensible people who report having had some kind of direct awareness of a divine being, and there are competent philosophers who endorse arguments for God's existence.
Friends of Dawkins might object: "Why pay attention to what philosophers have to say when, notoriously, they continue to disagree regarding the 'big questions', particularly, the existence of God?" Because, successful or not, philosophers offer the best rational thinking about such questions. Believers who think religion begins where reason falters may be able to make a case for the irrelevance of high-level philosophical treatments of religion - although, as I argued in "Philosophy and Faith," this move itself raises unavoidable philosophical questions that challenge religious faith. But those, like Dawkins, committed to believing only what they can rationally justify, have no alternative to engaging with the most rigorous rational discussions available. Dawkins' distinctly amateur philosophizing simply isn't enough.
