In their condescending assumption that belief in God could only be the product of wishful thinking, stupidity, ignorance, or intellectual dishonesty; in their corresponding refusal seriously to consider the possibility that that belief might be true and the arguments for it sound; and in their glib supposition that the only rational considerations relevant to the question are “scientific” ones, rather than philosophical; in all of these attitudes, Flew’s critics manifest the quintessential mindset of modern secularism. And insofar as its self-satisfied a priori dismissal of outsiders as benighted, and of defectors as wicked or mad, insulates it from ever having to deal with serious criticism, it is a mindset that echoes the closed-minded prejudice and irrationality it typically attributes to religious believers themselves.
