Pride of intellect is the next cause of Atheism. Don Juan sells himself to perdition for a liberal share of pleasure, but Faust hankers only after forbidden knowledge. This is of various kinds; but "of all kinds, that which has long had the most evil reputation of begetting Atheism is Physical Science." Again does the fervid Professor set lance in rest, and dash against this new foe to Theism, much as Don Quixote charged the famous windmill. But science, like the windmill, is too big and strong to suffer from such assaults. The "father of this sort of nonsense," in modern times was David Hume, who, we are elegantly informed, was "a very clever fellow, a very agreeable, gentlemanly fellow too." His "nonsense about causation" is to be traced to a want of reverence in his character. Indeed, it seems that all persons who adhere to a philosophy alien to Professor Blackie's have something radically wrong with them. Let this Edinburgh Professor rail as he may, David Hume's theory of causation will suffer no harm, and his contrast of human architecture, which is mechanism, with natural architecture, which is growth, will still form an insuperable obstacle to that "natural theology" which, as Garth Wilkinson says with grim humor, seeks to elicit, or rather "construct," "a scientific abstraction answering to the concrete figure of the Vulcan of the Greeks--that is to say a universal Smith"! Eventually Professor Blackie gets so sick of philosophers, that he turns from them to poets, who may more safely be trusted "in matters of healthy human sentiment." But here fresh difficulties arise. Although "a poet is naturally a religious animal," we find that the greatest of Roman poets Lucretius, was an Atheist, while even "some of our most brilliant notorieties in the modern world of song are not the most notable for piety." But our versatile Professor easily accounts for this by assuming that there "may be an idolatry of the imaginative, as well as of the knowing faculty." Never did natural historian so jauntily provide for every fact contravening his theories. Professor Blackie will never understand Atheism, or write profitably upon it, while he pursues this course. Let him restrain his discursive propensities, and deal scientifically with this one fact, which explodes his whole theory of Atheism. The supreme glory of our modern poetry is Shelley, and if ever a man combined splendor of imagination with keen intelligence and saintly character it was he. Raphael incarnate he seems, yet he stands outside all the creeds, and to his prophetic vision, in the sunlight of the world's great age begun anew, the-- Faiths and empires gleam Like wrecks of a dissolving dream.
