The leading adversaries of the deists appealed, like them, to reason, and, in appealing to reason, did much to undermine authority. The ablest defence of the faith, Bishop Butler’s Analogy (1736), is suspected of having raised more doubts than it appeased. This was the experience of William Pitt the Younger, and the Analogy made James Mill (the utilitarian) an unbeliever. The deists, argued that the unjust and cruel God of Revelation could not be the God of nature; Butler pointed to nature and said, There you behold cruelty and injustice. The argument was perfectly good against the optimism of Shaftesbury, but it plainly admitted of the conclusion—opposite to that which Butler wished to establish—that a just and beneficent God does not exist. Butler is driven to fall back on the sceptical argument that we are extremely ignorant; that all things [152] are possible, even eternal hell fire; and that therefore the safe and prudent course is to accept the Christian doctrine. It may be remarked that this reasoning, with a few modifications, could be used in favour of other religions, at Mecca or at Timbuctoo. He has, in effect, revived the argument used by Pascal that if there is one chance in any very large number that Christianity is true, it is a man’s interest to be a Christian; for, if it prove false, it will do him no harm to have believed it; if it prove true, he will be infinitely the gainer. Butler seeks indeed to show that the chances in favour amount to a probability, but his argument is essentially of the same intellectual and moral value as Pascal’s. It has been pointed out that it leads by an easy logical step from the Anglican to the Roman Church. Catholics and Protestants (as King Henry IV of France argued) agree that a Catholic may be saved; the Catholics assert that a Protestant will be damned; therefore the safe course is to embrace Catholicism.
