For ten chapters you have stood it, but not without protest. I know the feeling which is in your minds, and which has manifested itself in numerous criticisms of my ideas. That feeling may be briefly translated, perhaps, thus: “This is all very well, but – it isn’t true, not a bit! It’s only a fairy-tale that you have been telling us. Miracles don’t happen,” etc. I, on my part, have a feeling that unless I take your feeling in hand at once, and firmly deal with it, I had better put my shutters up, for you will have got into the way of regarding me simply as a source of idle amusement. Already I can perceive, from the expressions of some critics, that, so far as they are concerned, I might just as well not have written a word. Therefore at this point I pause, in order to insist once more upon what I began by saying.
The burden of your criticism is: “Human nature is always the same. I know my faults. But it is useless to tell me about them. I can’t alter them. I was born like that.” The fatal weakness of this argument is, first, that it is based on a complete falsity; and second, that it puts you in an untenable position. Human nature does change. Nothing can be more unscientific, more hopelessly medi?val, than to imagine that it does not. It changes like everything else. You can’t see it change. True! But then you can’t see the grass growing – not unless you arise very early.
Is human nature the same now as in the days of Babylonian civilisation, when the social machine was oiled by drenchings of blood? Is it the same now as in the days of Greek civilisation, when there was no such thing as romantic love between the sexes? Is it the same now as it was during the centuries when constant friction had to provide its own cure in the shape of constant war? Is it the same now as it was on March 2nd, 1819, when the British Government officially opposed a motion to consider the severity of the criminal laws (which included capital punishment for cutting down a tree, and other sensible dodges against friction), and were defeated by a majority of only nineteen votes? Is it the same now as in the year 1883, when the first S.P.C.C. was formed in England?
If you consider that human nature is still the same, you should instantly go out and make a bonfire of the works of Spencer, Darwin, and Wallace, and then return to enjoy the purely jocular side of the present volume. If you admit that it has changed, let me ask you how it has changed, unless by the continual infinitesimal efforts, upon themselves, of individual men, like you and me. Did you suppose it was changed by magic, or by acts of parliament, or by the action of groups on persons, and not of persons on groups? Let me tell you that human nature has changed since yesterday. Let me tell you that to-day reason has a more powerful voice in the directing of instinct than it had yesterday. Let me tell you that to-day the friction of the machines is less screechy and grinding than it was yesterday.
