The words "liberal" and "fundamentalist" are used today not so much to identify oneself as to label the enemy. From one side comes the accusation that the mind of the fundamentalist is closed, shuttered against the possibility of doubt and therefore against the recognition of hitherto unrecognized truth. From the other side comes the charge that liberals are so open to new ideas that they have no firm commitments at all, that every affirmation of faith must be held only tentatively, and that every dogma must, as a matter of principle, be challenged. There are terms of moral opprobrium that each side employs to attack the other: the fundamentalist is arrogant, blinkered, and culturally illiterate; the liberal is flabby, timid, and carried along by every new fashion of thought. From the point of view of the fundamentalist, doubt is sin; from the point of view of the liberal, the capacity for doubt is a measure of intellectual integrity and honesty.
