If Locke’s philosophy, by setting authority in its place and deriving all knowledge from experience, was a powerful aid to rationalism, his contemporary Bayle worked in the same direction by the investigation of history. Driven from France (see above, p. 107), he lived at Amsterdam, where he published his Philosophical Dictionary. He was really a freethinker, but he never dropped the disguise of orthodoxy, and this lends a particular piquancy to his work. He takes a delight in marshalling all the objections which heretics had made to essential Christian dogmas. He exposed without mercy the crimes and brutalities of David, and showed that this favourite of the Almighty was a person with whom one would refuse to shake hands. There was a great outcry at this unedifying candour. Bayle, in replying, adopted the attitude of Montaigne and Pascal, and opposed faith to reason. The theological virtue of faith, he said, consists in believing revealed truths simply and solely on God’s authority. If you believe in the immortality of the soul for [136] philosophical reasons, you are orthodox, but you have no part in faith. The merit of faith becomes greater, in proportion as the revealed truth surpasses all the powers of our mind; the more incomprehensible the truth and the more repugnant to reason, the greater is the sacrifice we make in accepting it, the deeper our submission to God. Therefore a merciless inventory of the objections which reason has to urge against fundamental doctrines serves to exalt the merits of faith. The Dictionary was also criticized for the justice done to the moral excellencies of persons who denied the existence of God. Bayle replies that if he had been able to find any atheistical thinkers who lived bad lives, he would have been delighted to dwell on their vices, but he knew of none such. As for the criminals you meet in history, whose abominable actions make you tremble, their impieties and blasphemies prove they believed in a Divinity. This is a natural consequence of the theological doctrine that the Devil, who is incapable of atheism, is the instigator of all the sins of men. For man’s wickedness must clearly resemble that of the Devil and must therefore be joined to a belief in God’s existence, since the Devil is not an atheist. And is it not a proof of the infinite wisdom of God that the worst criminals [137] are not atheists, and that most of the atheists whose names are recorded have been honest men? By this arrangement Providence sets bounds to the corruption of man; for if atheism and moral wickedness were united in the same persons, the societies of earth would be exposed to a fatal inundation of sin. There was much more in the same vein; and the upshot was, under the thin veil of serving faith, to show that the Christian dogmas were essentially unreasonable.
