Generally, instinctively, in the absence of any special reason, humanity hates the idea of anything being hidden–that is, it hates the idea of anything being successfully hidden. Hide-and-seek is a popular pastime; but it assumes the truth of the text, “Seek and ye shall find.” Ordinary mankind (gigantic and unconquerable in its power of joy) can get a great deal of pleasure out of a game called “hide the thimble,” but that is only because it is really a game of “see the thimble.” Suppose that at the end of such a game the thimble had not been found at all; suppose its place was unknown for ever: the result on the players would not be playful, it would be tragic. That thimble would hag-ride all their dreams. They would all die in asylums. The pleasure is all in the poignant moment of passing from not knowing to knowing. Mystery stories are very popular, especially when sold at sixpence; but that is because the author of a mystery story reveals. He is enjoyed not because he creates mystery, but because he destroys mystery. Nobody would have the courage to publish a detective-story which left the problem exactly where it found it. That would rouse even the London public to revolution. No one dare publish a detective-story that did not detect.
There are three broad classes of the special things in which human wisdom does permit privacy. The first is the case I have mentioned–that of hide-and-seek, or the police novel, in which it permits privacy only in order to explode and smash privacy. The author makes first a fastidious secret of how the Bishop was murdered, only in order that he may at last declare, as from a high tower, to the whole democracy the great glad news that he was murdered by the governess. In that case, ignorance is only valued because being ignorant is the best and purest preparation for receiving the horrible revelations of high life. Somewhat in the same way being an agnostic is the best and purest preparation for receiving the happy revelations of St. John.
This first sort of secrecy we may dismiss, for its whole ultimate object is not to keep the secret, but to tell it. Then there is a second and far more important class of things which humanity does agree to hide. They are so important that they cannot possibly be discussed here. But every one will know the kind of things I mean. In connection with these, I wish to remark that though they are, in one sense, a secret, they are also always a “secret de Polichinelle.” Upon sex and such matters we are in a human freemasonry; the freemasonry is disciplined, but the freemasonry is free. We are asked to be silent about these things, but we are not asked to be ignorant about them. On the contrary, the fundamental human argument is entirely the other way. It is the thing most common to humanity that is most veiled by humanity. It is exactly because we all know that it is there that we need not say that it is there.
Then there is a third class of things on which the best civilisation does permit privacy, does resent all inquiry or explanation. This is in the case of things which need not be explained, because they cannot be explained, things too airy, instinctive, or intangible–caprices, sudden impulses, and the more innocent kind of prejudice. A man must not be asked why he is talkative or silent, for the simple reason that he does not know. A man is not asked (even in Germany) why he walks slow or quick, simply because he could not answer. A man must take his own road through a wood, and make his own use of a holiday. And the reason is this: not because he has a strong reason, but actually because he has a weak reason; because he has a slight and fleeting feeling about the matter which he could not explain to a policeman, which perhaps the very appearance of a policeman out of the bushes might destroy. He must act on the impulse, because the impulse is unimportant, and he may never have the same impulse again. If you like to put it so he must act on the impulse because the impulse is not worth a moment’s thought. All these fancies men feel should be private; and even Fabians have never proposed to interfere with them.
