This is disputed by M. Lanson, an always weighty authority. He writes (p. 464) that Pascal was "neither mad nor ill" when he gave himself up wholly to religion. But ill he certainly was. He had chronically suffered from intense pains in the head from his eighteenth year; and M. Lanson admits (p. 451) that the Pensées were written in intervals of acute suffering. This indeed understates the case. Pascal several times told his family that since the age of eighteen he had never passed a day without pain. His sister, Madame Perier, in her biographical sketch, speaks of him as suffering "continual and ever-increasing maladies," and avows that the four last years of his life, in which he penned the fragments called Pensées, "were but a continual languishment." The Port Royal preface of 1670 says the same thing, speaking of the "four years of languor and malady in which he wrote all we have of the book he planned," and calling the Pensées "the feeble essays of a sick man." Cp. Pascal's Prière pour demander à Dieu le bon usage des maladies: and Owen French Skeptics, pp. 746, 784. Doubtless the levity and licence of the libertins in high places [576] confirmed him in his revolt against unbelief; but his own credence was an act rather of despairing emotion than of rational conviction. The man who advised doubters to make a habit of causing masses to be said and following religious rites, on the score that cela vous fera croire et vous abêtira--"that will make you believe and will stupefy you" [577]--was a pathological case; and though the whole Jansenist movement latterly stood for a reaction against freethinking, it can hardly be doubted that the Pensées generally acted as a solvent rather than as a sustainer of religious beliefs. [578] This charge was made against them immediately on their publication by the Abbé de Villars, who pointed out that they did the reverse of what they claimed to do in the matter of appealing to the heart and to good sense, since they set forth all the ordinary arguments of Pyrrhonism, denied that the existence of God could be established by reason or philosophy, and staked the case on a "wager" which shocked good sense and feeling alike. "Have you resolved," asks this critic in dialogue, "to make atheists on pretext of combatting them?" [579]
