If Voltaire had studied Hume, moreover, he might have learnt how futile and inappropriate it is in the long run to examine a religion otherwise than in its most fundamental and comprehensive general ideas, and how narrow and superficial would every philosophic appreciation ultimately find what he called refutation by facts. For his own immediate purpose, which was to cover the church and its creed with ridicule, the method of collecting all the ludicrous, immoral, and inconsistent circumstances in the Scriptures and their current interpretation, was, as we have already said, a weapon potent enough. Voltaire, however, not only did not use, he never understood nor perceived, the fact that a religion rests for its final base on a certain small number of ideas, or that it is only by touching these, by loosening the firmness of their hold, by revealing their want of coherency and consistency with other accepted ideas, that we can expect to shake the superstructure. For example, if only the official exponents of religion had not been so firmly bent on making the feeblest of all their ramparts into their very citadel, it would have been a very small thing to urge the truly singular quality of such miracles as those of the water made wine at Cana, of the cursing of the barren fig-tree, of the unfortunate swine who rushed violently down a steep place and were choked. These were legends that from the right point of view of religion were not worth defending, any more than from the right point of view of truth they were worth attacking. The details of the use of a supernaturally conferred power may best be let alone, until the probability of the existence and bestowal of such power has been discussed and decided. The important issue and matter of vital concern turned upon the general idea of the miraculous; yet this was what Voltaire, perhaps from an instinctive consciousness of the little capacity he possessed for genuine speculation, postponed to the really secondary purpose of disparaging particular cases of miraculous performance.
