The sages, it is often said, can see no answer to the riddle of religion. But the trouble with our sages is not that they cannot see the answer; it is that they cannot even see the riddle. They are like children so stupid as to notice nothing paradoxical in the playful assertion that a door is not a door. The modern latitudinarians speak, for instance, about authority in religion not only as if there were no reason in it, but as if there had never been any reason for it. Apart from seeing its philosophical basis, they cannot even see its historical cause. Religious authority has often, doubtless, been oppressive or unreasonable; just as every legal system (and especially our present one) has been callous and full of a cruel apathy. It is rational to attack the police; nay, it is glorious. But the modern critics of religious authority are like men who should attack the police without ever having heard of burglars. For there is a great and possible peril to the human mind: a peril as practical as burglary. Against it religious authority was reared, rightly or wrongly, as a barrier. And against it something certainly must be reared as a barrier, if our race is to avoid ruin.
