The truth is that the tradition of Christianity (which is still the only coherent ethic of Europe) rests on two or three paradoxes or mysteries which can easily be impugned in argument and as easily justified in life. One of them, for instance, is the paradox of hope or faith– that the more hopeless is the situation the more hopeful must be the man. Stevenson understood this, and consequently Mr. Moore cannot understand Stevenson. Another is the paradox of charity or chivalry that the weaker a thing is the more it should be respected, that the more indefensible a thing is the more it should appeal to us for a certain kind of defence. Thackeray understood this, and therefore Mr. Moore does not understand Thackeray.
Now, one of these very practical and working mysteries in the Christian tradition, and one which the Roman Catholic Church, as I say, has done her best work in singling out, is the conception of the sinfulness of pride. Pride is a weakness in the character; it dries up laughter, it dries up wonder, it dries up chivalry and energy. The Christian tradition understands this; therefore Mr. Moore does not understand the Christian tradition.
For the truth is much stranger even than it appears in the formal doctrine of the sin of pride. It is not only true that humility is a much wiser and more vigorous thing than pride. It is also true that vanity is a much wiser and more vigorous thing than pride. Vanity is social–it is almost a kind of comradeship; pride is solitary and uncivilized. Vanity is active; it desires the applause of infinite multitudes; pride is passive, desiring only the applause of one person, which it already has. Vanity is humorous, and can enjoy the joke even of itself; pride is dull, and cannot even smile. And the whole of this difference is the difference between Stevenson and Mr. George Moore, who, as he informs us, has “brushed Stevenson aside.” I do not know where he has been brushed to, but wherever it is I fancy he is having a good time, because he had the wisdom to be vain, and not proud. Stevenson had a windy vanity; Mr. Moore has a dusty egoism. Hence Stevenson could amuse himself as well as us with his vanity; while the richest effects of Mr. Moore’s absurdity are hidden from his eyes.
If we compare this solemn folly with the happy folly with which Stevenson belauds his own books and berates his own critics, we shall not find it difficult to guess why it is that Stevenson at least found a final philosophy of some sort to live by, while Mr. Moore is always walking the world looking for a new one.
Stevenson had found that the secret of life lies in laughter and humility. Self is the gorgon. Vanity sees it in the mirror of other men and lives. Pride studies it for itself and is turned to stone.
