"The mystic is a power; he compels a multitude of followers, because he offers an attraction greater than the facts of science; he tells of a mystery profounder than any problem solved by patient investigation, because his mystery is incomprehensible even by himself; and in fear lest any should comprehend it, he disguises the approach with an array of lesser mysteries, man-made; with terminologies, symbologies and high talk of esotericism too fearful for any save the initiate. "But we must preserve our mystic in some form against the awful time when science shall have determined a limit; when the long history of evolution shall be written in full, and every stage of world-building shall be made plain. When the cycle of atomic dust to atomic dust is demonstrated, and the detail of the life-process is taught and understood, we shall have a fierce need for the mystic to save us from the futility of a world we understand, to lie to us if need be, to inspirit our material and regular minds with some breath of delicious madness. We shall need the mystic then, or the completeness of our knowledge will drive us at last to complete the dusty circle in our eagerness to escape from a world we understand.... "See how man clings to his old and useless traditions; see how he opposes at every step the awful force of progress. At each stage he protests that the thing that is, is good, or that the thing that was and has gone, was better. He despises new knowledge and fondly clings to the belief that once men were greater than they now are. He looks back to the more primitive, and endows it with that mystery he cannot find in his own times. So have men ever looked lingeringly behind them. It is an instinct, a great and wonderful inheritance that postpones the moment of disillusionment. "We are still mercifully surrounded with the countless mysteries of every-day experience, all the evidences of the unimaginable stimulus we call life. Would you take them away? Would you resolve life into a disease of the ether--a disease of which you and I, all life and all matter, are symptoms? Would you teach that to the child, and explain to him that the wonder of life and growth is no wonder, but a demonstrable result of impeded force, to be evaluated by the application of an adequate formula? "You and I," said Challis, "are children in the infancy of the world. Let us to our play in the nursery of our own times. The day will come, perhaps, when humanity shall have grown and will have to take upon itself the heavy burden of knowledge. But you need not fear that that will be in our day, nor in a thousand years. "Meanwhile leave us our childish fancies, our little imaginings, our hope--children that we are--of those impossible mysteries beyond the hills ... beyond the hills."
