It is true that some speak lightly and loosely of insanity as in itself attractive. But a moment's thought will show that if disease is beautiful, it is generally some one else's disease. A blind man may be picturesque; but it requires two eyes to see the picture. And similarly even the wildest poetry of insanity can only be enjoyed by the sane. To the insane man his insanity is quite prosaic, because it is quite true. A man who thinks himself a chicken is to himself as ordinary as a chicken. A man who thinks he is a bit of glass is to himself as dull as a bit of glass. It is the homogeneity of his mind which makes him dull, and which makes him mad. It is only because we see the irony of his idea that we think him even amusing; it is only because he does not see the irony of his idea that he is put in the asylum at all. In short, oddities only strike ordinary people. Oddities do not strike odd people. This is why ordinary people have a much more exciting time; while odd people are always complaining of the dulness of life.
The madman's explanation of a thing is always complete, and often in a purely rational sense satisfactory. Or, to speak more strictly, the insane explanation, if not conclusive, is at least unanswerable; this may be observed specially in the two or three commonest kinds of madness. If a man says (for instance) that men have a conspiracy against him, you cannot dispute it except by saying that all the men deny that they are conspirators; which is exactly what conspirators would do. His explanation covers the facts as much as yours. Or if a man says that he is the rightful King of England, it is no complete answer to say that the existing authorities call him mad; for if he were King of England that might be the wisest thing for the existing authorities to do. Or if a man says that he is Jesus Christ, it is no answer to tell him that the world denies his divinity; for the world denied Christ's.
The lunatic's theory explains a large number of things, but it does not explain them in a large way. I mean that if you or I were dealing with a mind that was growing morbid, we should be chiefly concerned not so much to give it arguments as to give it air, to convince it that there was something cleaner and cooler outside the suffocation of a single argument. Suppose, for instance, it were the first case that I took as typical; suppose it were the case of a man who accused everybody of conspiring against him. If we could express our deepest feelings of protest and appeal against this obsession, I suppose we should say something like this: "Oh, I admit that you have your case and have it by heart, and that many things do fit into other things as you say. I admit that your explanation explains a great deal; but what a great deal it leaves out! Are there no other stories in the world except yours; and are all men busy with your business? Suppose we grant the details; perhaps when the man in the street did not seem to see you it was only his cunning; perhaps when the policeman asked you your name it was only because he knew it already. But how much happier you would be if you only knew that these people cared nothing about you! How much larger your life would be if your self could become smaller in it; if you could really look at other men with common curiosity and pleasure; if you could see them walking as they are in their sunny selfishness and their virile indifference! You would begin to be interested in them, because they were not interested in you. You would break out of this tiny and tawdry theatre in which your own little plot is always being played, and you would find yourself under a freer sky, in a street full of splendid strangers."
