But here the reality of it all broke upon me--burst out with its thundering sense of truth. Mad the blind beggar might be; yet there, before my very eyes, in those motionless objects, was the secret of perpetual motion. Rust, decay, change--the obstinate metal of the iron rod, the flimsy substance of the tin pot, always under the condition of change; rusting in his pocket where they had lain for fifteen years--never quiescent, never still, always moving--moving--moving--in obedience to the inviolable law of change, as we all, in servile obedience to that law as well, are moving continually, from childhood into youth, youth to middle-age--middle-age to senility--then death, the last change of all. All this giant structure of manhood, the very essence of complicated intricacy compared to that piece of rod iron, passing into the dust from which the thousands of years had contrived to make it. What more could one want of perpetual motion than that? I looked up into his face again. "You’ve taught me a wonderful lesson," I said quietly. "Ah," he replied--"it’s all there--all there--the whole secret of it; if only I had the eyes to put it together." If he only had the eyes? Have _any_ of us the eyes? Have any of us the eyes? When he had finished, he folded it slowly and put it back in his pocket. "Well----?" he said. His heart was beating with anticipation, with apprehension, with exaltation. With one beat he knew she must think it was good. It was his best. He had just done it and, when you have just done it, you are apt to think that. But with another beat, he felt she was going to say the conventional thing--to call it charming--to say--"But how nice." It would be far better if she said it was all wrong, that it struck a wrong note, that its composition was ill. One can believe that about one’s work--but that it is charming, that it is nice--never! For that moment Destiny swung in a balance, poised upon the agate of chance. What was she going to say? It all depended upon that. But she was so silent. She sat so still. Mice are still when you startle them; then, when they collect their wits, they scamper away. Suddenly she rose to her feet. "Will you be here in the Gardens to-morrow morning at this time," she said--"Then I’ll tell you how very much I liked it." CHAPTER X THE NEED FOR INTUITION In such a world as this, anything which is wholly sane is entirely uninteresting. But--thank heaven for it!--madness is everywhere, in every corner, at every turning. You will not even find complete sanity in a Unitarian; in fact, some of the maddest people I have ever met have been Unitarians. Yet theirs is an aggravating madness. You can have no sympathy with a man who believes himself sane.
