For his own sake Professor Blackie should a little curb his proneness to the use of uncomplimentary epithets. He does himself injustice when he condescends to describe David Hume's theory of causation as "wretched cavil." Carlyle is more just to this great representative of an antagonistic school of thought. He exempts him from the sweeping condemnation of his contemporaries in Scottish prose literature, and admits that he was "too rich a man to borrow" from France or elsewhere. And surely Hume was no less honest than rich in thought. Jest and captiousness were entirely foreign to his mind. Wincing under his inexorable logic, the ontologist may try to console himself with the thought that the great sceptic was playing with arguments like a mere dialectician of wondrous skill; but in reality Hume was quite in earnest, and always meant what he said. We may also observe that it is Professor Blackie and not Darwin who suffers from the asking of such questions as these:--"What monkey ever wrote an epic poem, or composed a tragedy or a comedy, or even a sonnet? What monkey professed his belief in any thirty-nine articles, or well-compacted Calvinistic confession, or gave in his adhesion to any Church, established or disestablished?" If Mr. Darwin heard these questions he might answer with a good humored smile, "My dear sir, you quite mistake my theories, and your questions travesty them. I would further observe that while the composition of poems would unquestionably be creditable to monkeys, I, who have some regard for them as relatives, however distant, am heartily glad they have never done any of the other things you mention, which I deem a negative proof that their reason, though limited, is fortunately sane." Professor Blackie's opening chapter on "Presumptions" fully justifies its title. The general consent of mankind in favor of Theism is assumed to have established its validity, and to have put Atheists altogether out of court; and a long list of illustrious Theists, from Solomon to Hegel, is contrasted with a meagre catalogue of Atheists, comprising only the names of David Hume, Jeremy Bentham, and John Stuart Mill. * Confucius and Buddha are classed apart, as lying "outside of our Western European Culture altogether," but with a promise that "in so far as they seem to have taught a morality without religion, or a religion without God, we shall say a word or two about them by-and-by." So far as Buddha is concerned this promise is kept; but in relation to Confucius it is broken. Probably the Chinese sage was found too tough and embarrassing a subject, and so it was thought expedient to ignore him for the more tractable prophet of India, whose doctrine of Transmigration might with a little sophistry be made to resemble the Christian doctrine of Immortality, and his Nirvana the Kingdom of Heaven.
