Voltaire at first seems to have been captivated by the doctrine of Pope’s _Essay on Man._ He, however, afterwards wrote: “Those who exclaim that all is well are charlatans. Shaftesbury, who first made the fable fashionable, was a very unhappy man. I have seen Bolingbroke a prey to vexation and rage, and Pope, whom he induced to put this sorry jest into verse, was as much to be pitied as any man I have ever known, misshapen in body, dissatisfied in mind, always ill, always a burden to himself, and harassed by a hundred enemies to his very last moment. Give me, at least, the names of some happy men who will tell me ’All is well.’” His optimism got injured during his journey through life, and was completely shattered by the earthquake at Lisbon in 1755. On this subject he produced a grave poem, notable for its confession of the difficult reconciling the evil of the world with the Beneficence of God? The same subject was dealt with in grotesque fashion in _Candide_, one of the wisest as well as one of the wittiest of works. A philosophy was never more triumphantly reasoned and ridiculed out of court than is optimism in _Candide_. Incident crowds on incident, argument jostles satire, illustration succeeds raillery, all to show the miseries of existence disprove this being the best of all possible worlds. At one moment we are forced to tears at contemplating the atrocities of inhumanity; the next we are forced to laugh at its absurdities. Prudes may be shocked at some incidents. Voltaire said he was not born to sing the praises of saints. He was himself no saint, but rather one of those sinners who had done the world more good than all its saints. But the influence of the work is profoundly good. It is purely humanitarian, War, persecution for religion, slavery, torture, and all forms of cruelty are made hateful by a recital of their facts; and all this is done in so charming, even flippant a manner, that we are laughing all the while we are most profoundly moved. Schopenhauer and Hartmann both enjoyed life, while Voltaire was an invalid most of his days; but they never threw into their pessimism the gaiety of _Candide_. And his peculiarity is, that he makes all man’s lower instincts ridiculous as well as detestable.
