4. Machinery has poetry in it because the three immeasurable ideas expressed by machinery are the three immeasurable ideas of poetry and of the imagination and the soul--infinity and the two forms of infinity, the liberty and the unity of man. 5. These immeasurable ideas are consummately expressed by machinery because machinery expresses them in the only way that immeasurable ideas can ever be expressed: (1) by literally doing the immeasurable things, (2) by suggesting that it is doing them. To the man who is in the mood of looking at it with his whole being, the machine is beautiful because it is the mightiest and silentest symbol the world contains of the infinity of his own life, and of the liberty and unity of all men's lives, which slowly, out of the passion of history is now being wrought out before our eyes upon the face of the earth. 6. It is only from the point of view of a nightingale or a sonnet that the aesthetic form of a machine, if it is a good machine, can be criticised as unbeautiful. The less forms dealing with immeasurable ideas are finished forms the more symbolic and speechless they are; the more they invoke the imagination and make it build out on God, and upon the Future, and upon Silence, the more artistic and beautiful and satisfying they are. 7. The first great artist a modern or machine age can have, will be the man who brings out for it the ideas behind its machines. These ideas--the ones the machines are daily playing over and about the lives of all of us--might be stated roughly as follows: The idea of the incarnation--the god in the body of the man. The idea of liberty--the soul's rescue from others. The idea of unity--the soul's rescue from its mere self. The idea of the Spirit--the Unseen and Intangible. The idea of immortality. The cosmic idea of God. The practical idea of invoking great men. The religious idea of love and comradeship. And nearly every other idea that makes of itself a song or a prayer in the human spirit. PART FOUR IDEAS BEHIND THE MACHINES I THE IDEA OF INCARNATION "_I sought myself through earth and fire and seas, And found it not--but many things beside; Behemoth old, Leviathans that ride. And protoplasm, and jellies of the tide. Then wandering upward through the solid earth With its dim sounds, potential rage and mirth, I faced the dim Forefather of my birth, And thus addressed Him: 'All of you that lie Safe in the dust or ride along the sky-- Lo, these and these and these! But where am I?_'"
