From the book's website:

Are physicists and biologists willing to believe in anything so long as it is not religious thought? Close enough.

Is there a narrow and oppressive orthodoxy of thought and opinion within the sciences? Close enough.

Does anything in the sciences or in their philosophy justify the claim that religious belief is irrational? Not even ballpark.

I guess there is some tension between "narrow and oppressive orthodoxy of thought and opinion" and "willing to believe in anything"...
