I have remarked that theologians at this time generally took the line of basing Christianity on reason and not on faith. An interesting little book, Christianity not founded on Argument, couched in the form of a letter to a young gentleman at Oxford, by Henry Dodwell (Junior), appeared in 1741, and pointed out the dangers of such confidence in reason. It is an ironical development of the principle of Bayle, working out the thesis that Christianity is essentially unreasonable, and that if you want to believe, reasoning is fatal. The cultivation of faith and reasoning produce contrary effects; the philosopher is disqualified for Divine influences by his very progress in carnal wisdom; the Gospel must be received with all the obsequious submission of a babe who has no other disposition but to learn his lesson. Christ did not propose his doctrines to investigation; he did not lay the arguments for his mission before his disciples and give them time to consider [148] calmly of their force, and liberty to determine as their reason should direct them; the apostles had no qualifications for the task, being the most artless and illiterate persons living. Dodwell exposes the absurdity of the Protestant position. To give all men liberty to judge for themselves and to expect at the same time that they shall be of the Preacher’s mind is such a scheme for unanimity as one would scarcely imagine any one could be weak enough to devise in speculation and much less that any could ever be found hardy enough to avow and propose it to practice. The men of Rome “shall rise up in the judgment (of all considering persons) against this generation and shall condemn it; for they invented but the one absurdity of infallibility, and behold a greater absurdity than infallibility is here.”

I have still to speak of the (Third) Earl of Shaftesbury, whose style has rescued his writings from entire neglect. His special interest was ethics. While the valuable work of most of the heterodox writers of this period lay in their destructive criticism of supernatural religion, they clung, as we have seen, to what was called natural religion— the belief in a kind and wise personal God, who created the world, governs it by natural laws, and desires our happiness. The idea [149] was derived from ancient philosophers and had been revived by Lord Herbert of Cherbury in his Latin treatise On Truth (in the reign of James I). The deists contended that this was a sufficient basis for morality and that the Christian inducements to good behaviour were unnecessary. Shaftesbury in his Inquiry concerning Virtue (1699) debated the question and argued that the scheme of heaven and hell, with the selfish hopes and fears which they inspire, corrupts morality and that the only worthy motive for conduct is the beauty of virtue in itself. He does not even consider deism a necessary assumption for a moral code; he admits that the opinion of atheists does not undermine ethics. But he thinks that the belief in a good governor of the universe is a powerful support to the practice of virtue. He is a thorough optimist, and is perfectly satisfied with the admirable adaptation of means to ends, whereby it is the function of one animal to be food for another. He makes no attempt to reconcile the red claws and teeth of nature with the beneficence of its powerful artist. “In the main all things are kindly and well disposed.” The atheist might have said that he preferred to be at the mercy of blind chance than in the hands of an autocrat who, if he pleased Lord Shaftesbury’s sense [150] of order, had created flies to be devoured by spiders. But this was an aspect of the universe which did not much trouble thinkers in the eighteenth century. On the other hand, the character of the God of the Old Testament roused Shaftesbury’s aversion. He attacks Scripture not directly, but by allusion or with irony. He hints that if there is a God, he would be less displeased with atheists than with those who accepted him in the guise of Jehovah. As Plutarch said, “I had rather men should say of me that there neither is nor ever was such a one as Plutarch, than they should say ‘There was a Plutarch, an unsteady, changeable, easily provokable and revengeful man.’ ” Shaftesbury’s significance is that he built up a positive theory of morals, and although it had no philosophical depth, his influence on French and German thinkers of the eighteenth century was immense.

In some ways perhaps the ablest of the deists, and certainly the most scholarly, was Rev. Conyers Middleton, who remained within the Church. He supported Christianity on grounds of utility. Even if it is an imposture, he said, it would be wrong to destroy it. For it is established by law and it has a long tradition behind it. Some traditional religion is necessary and it would [151] be hopeless to supplant Christianity by reason. But his writings contain effective arguments which go to undermine Revelation. The most important was his Free Inquiry into Christian miracles (1748), which put in a new and dangerous light an old question: At what time did the Church cease to have the power of performing miracles? We shall see presently how Gibbon applied Middleton’s method.

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.

I have dwelt at some length upon some of the English deists, because, while they occupy an important place in the history of [153] rationalism in England, they also supplied, along with Bayle, a great deal of the thought which, manipulated by brilliant writers on the other side of the Channel, captured the educated classes in France. We are now in the age of Voltaire. He was a convinced deist. He considered that the nature of the universe proved that it was made by a conscious architect, he held that God was required in the interests of conduct, and he ardently combated atheism. His great achievements were his efficacious labour in the cause of toleration, and his systematic warfare against superstitions. He was profoundly influenced by English thinkers, especially Locke and Bolingbroke. This statesman had concealed his infidelity during his lifetime except from his intimates; he had lived long as an exile in France; and his rationalistic essays were published (1754) after his death. Voltaire, whose literary genius converted the work of the English thinkers into a world-force, did not begin his campaign against Christianity till after the middle of the century, when superstitious practices and religious persecutions were becoming a scandal in his country. He assailed the Catholic Church in every field with ridicule and satire. In a little work called The Tomb of Fanaticism (written 1736, [154] published 1767), he begins by observing that a man who accepts his religion (as most people do) without examining it is like an ox which allows itself to be harnessed, and proceeds to review the difficulties in the Bible, the rise of Christianity, and the course of Church history; from which he concludes that every sensible man should hold the Christian sect in horror. “Men are blind to prefer an absurd and sanguinary creed, supported by executioners and surrounded by fiery faggots, a creed which can only be approved by those to whom it gives power and riches, a particular creed only accepted in a small part of the world—to a simple and universal religion.” In the Sermon of the Fifty and the Questions of Zapata we can see what he owed to Bayle and English critics, but his touch is lighter and his irony more telling. His comment on geographical mistakes in the Old Testament is: “God was evidently not strong in geography.” Having called attention to the “horrible crime” of Lot’s wife in looking backward, and her conversion into a pillar of salt, he hopes that the stories of Scripture will make us better, if they do not make us more enlightened. One of his favourite methods is to approach Christian doctrines as a person who had just heard of the existence of Christians or Jews for the first time in his life. [155] His drama, Saul (1763), which the police tried to suppress, presents the career of David, the man after God’s own heart, in all its naked horror. The scene in which Samuel reproves Saul for not having slain Agag will give an idea of the spirit of the piece.

SAMUEL: God commands me to tell you that he repents of having made you king.

SAUL: God repents! Only they who commit errors repent. His eternal wisdom cannot be unwise. God cannot commit errors.

SAMUEL: He can repent of having set on the throne those who do.

SAUL: Well, who does not? Tell me, what is my fault?

SAMUEL: You have pardoned a king.
