Romance seeks to divide certain people from the lump of humanity, as the statue is divided from the lump of marble. We read a good novel not in order to know more people, but in order to know fewer. Instead of the humming swarm of human beings, relatives, customers, servants, postmen, afternoon callers, tradesmen, strangers who tell us the time, strangers who remark on the weather, beggars, waiters, and telegraph-boys — instead of this bewildering human swarm which passes us every day, fiction asks us to follow one figure (say the postman) consistently through his ecstasies and agonies. That is what makes one so impatient with that type of pessimistic rebel who is always complaining of the narrowness of his life, and demanding a larger sphere. Life is too large for us as it is: we have all too many things to attend to. All true romance is an attempt to simplify it, to cut it down to plainer and more pictorial proportions. What dullness there is in our life arises mostly from its rapidity: people pass us too quickly to show us their interesting side. By the end of the week we have talked to a hundred bores; whereas, if we had stuck to one of them, we might have found ourselves talking to a new friend, or a humourist, or a murderer, or a man who has seen a ghost.
I do not believe that there are any ordinary people. That is, I do not believe that there are any people whose lives are really humdrum or whose characters are really colourless. But the trouble is that one can so quickly see them all in a lump, like a land surveyor, and it would take so long to see them one by one as they really are, like a great novelist. Looking out of the window, I see a very steep little street, with a row of prim little houses breaking their necks downhill in a most decorous single file. If I were landlord of that street, or agent for that street, or policeman at the corner of that street, or visiting philanthropist making myself objectionable down that street, I could easily take it all in at a glance, sum it all up, and say, “Houses at £40 a year.” But suppose I could be father confessor to that street, how awful and altered it would look! Each house would be sundered from its neighbour as by an earthquake, and would stand alone in a wilderness of the soul. I should know that in this house a man was going mad with drink, that in that a man had kept single for a woman, that in the next a woman was on the edge of abysses, that in the next a woman was living an unknown life which might in more devout ages have been gilded in hagiographies and made a fountain of miracles. People talk much of the quarrel between science and religion; but the deepest difference is that the individual is so much bigger than the average, that the inside of life is much larger than the outside.
