The realistic novel, we know from Zola, that apostle of insufficient insight, is based on "human documents," and "human documents" are made up of "facts." _But in human life there are no facts._ This is not a paradox, but a "fact." Life is in the eye of the observer. The humour or the pity of it belongs entirely to the spectator, and depends upon the gift of vision he brings. There are no facts, like bricks, to build stories with. What, pray, in the realm of human life _is_ a fact? By no means a stubborn thing, as the proverb pretends. On the contrary, a most pliant, shifting, chameleon-coloured thing, as flexible as figures in the hands of the statistician. What is commonly called a fact is merely a one-sided piece of information, a dead thing, not the series of complex, mutually inter-working relations that constitutes a fact as it exhibits itself to the literary vivisectionist. I walked with a friend in a shabby district of central London, a region that had once been genteel, but was now broken up into apartments. Squalid babies, with wan, pathetic faces, pullulated on the doorsteps; they showed from behind dingy windows at the breasts of haggard women. The fronts of the houses were black, the plaster had crumbled away, the paint had peeled off. It was the ruins of a minor Carthage, and, like Marius, I was lost in mournful reverie; my companion remarked, "These houses are going up; they now pay 7 per cent." He was perfectly justified. There are a hundred ways of looking at any fact. The historian, the scientist, the economist, the poet, the philanthropist, the novelist, the anarchist, the intelligent foreigner,--each would take away a different impression from the street, and all these impressions would be facts, all equally valid, all equally true, and all equally false. Life, I repeat, is in the eye of the observer. What is farce to you is often tragedy to the actual performer. The man who slips over a piece of orange peel, or chases his hat along the muddy pavement, is rarely conscious of the humour of the situation. On the other hand, you shall see persons involved in heartrending tragedies to whom the thing shows as farce, like little children playing in churchyards or riding tombstones astride. To the little imps of comedy, who, according to Mr. Meredith, sit up aloft, holding their sides at the spectacle of mankind, to the Spirit of the world, Beholding the absurdities of men, Their vaunts, their feats, ...
