'Everywhere, in the pulpit, in the coffee-houses, in every pamphlet, argument on the origin of evil, on the goodness of God, and the constitution of the world was rife. Into the prevailing topic of polite conversation Bolingbroke, who returned from exile in 1723, was drawn by the bent of his native genius. Pope followed the example and impulse of his friend's more powerful mind. Thus much there was of special suggestion. But the arguments or topics of the poem are to be traced to books in much vogue at the time; to Shaftesbury's _Characteristics_ (1711), King on the _Origin of Evil_ (1702), and particularly to Leibnitz, _Essais de Théodicée_ (1710).' In admitting that Pope followed the impulse of a more powerful mind, Mr. Pattison asserts as much perhaps as can be known with certainty as to Bolingbroke's influence, but it is reasonable to believe that the close intercourse of the two men did immensely sway the more impressionable, and, so far as philosophy is concerned, the more ignorant of the two. Mr. Pattison also overlooks the fact that Pope confessed to Warburton that he had never read a line of Leibnitz in his life. That the poet acknowledges his large debt to Bolingbroke, and that Bolingbroke confesses it was due, is all that can be declared with certainty. That which makes the _Essay_ worthy the reading is the fruit, not of the argument but of the poetry, and for that Pope trusted to his own genius. His attempt to 'vindicate the ways of God to man' is confused and contradictory, and no modern reader, perplexed with the mystery of existence, is likely to gain aid from Pope. Nominally a Roman Catholic, and in reality a deist, apart from poetry he does not seem to have had strong convictions on any subject, and was content to be swayed by the opinions current in society. In undertaking to write an ethical work like the _Essay_ his ambition was greater than his strength, yet if Pope's philosophy does not 'find' us, to use Coleridge's phrase, it did appeal to a large number of minds in his own day, and had not lost its popularity at a later period. The poem has been frequently translated into French, into Italian, and into German; it was pronounced by Voltaire to be the most useful and sublime didactic poem ever written in any language; it was admired by Kant and quoted in his lectures; and it received high praise from the Scotch philosopher, Dugald Stewart. The charm of poetical expression is lost or nearly lost in translations, and while the sense may be retained the aroma of the verse is gone. The popularity of the _Essay_ abroad is therefore not easily to be accounted for, unless we accept the theory that the shallow creed on which it is based suited an age less earnest than our own.[22]
