...You don't automatically produce a defeater for Christian belief just by standing on your roof and proclaiming (even loudly and slowly),"God is dead!" (Not even if you add: "And everybody I know says so too.") Nor can you call Christian belief (or anything else) into question just by declaring, "I hereby call that into question!" You can't destroy a way of thinking just by announcing, "I hereby destroy that way of thinking!" This will not do the job, not even if it is embodied in writing of coruscating wit and style, and not even if you adopt a superior air and elegant gestures while intoning it. Something further is required.
