“Faith” is not in fact a rejection of reason, but simply a lazy acceptance of bad reasons. “Faith” is the pseudo-justification that some people trot out when they want to make claims without the necessary evidence.
And he gives an example (faith as circular reasoning/question begging):
Each religion makes scores of purportedly factual assertions about everything from the creation of the universe to the afterlife. But on what grounds can believers presume to know that these assertions are true? The reasons they give are various, but the ultimate justification for most religious people’s beliefs is a simple one: we believe what we believe because our holy scriptures say so. But how, then, do we know that our holy scriptures are factually accurate? Because the scriptures themselves say so. Theologians specialize in weaving elaborate webs of verbiage to avoid saying anything quite so bluntly, but this gem of circular reasoning really is the epistemological bottom line on which all “faith” is grounded. In the words of Pope John Paul II: “By the authority of his absolute transcendence, God who makes himself known is also the source of the credibility of what he reveals.”  It goes without saying that this begs the question of whether the texts at issue really were authored or inspired by God, and on what grounds one knows this.
Nicely, nicely put.
