The machine was not. He reached his mind into emptiness and seized it. Even yet he cannot realize what he has done. Out of the free elemental stuff of the universe, visible and invisible, some of it imponderable, such as lightning, he has invented a class of typhonic, mindless organisms, exempt from the will of nature. We have no understanding of creation, its process or meaning. The machine is the externalized image of man’s thoughts. It is furthermore an extension of his life, for we perceive as an economic fact that human existence in its present phase, on its present scale, could not continue in its absence. And what are we ourselves, life to begin with, if not an image of thought? Perhaps it is true as a principle of creation that the image and its creator must co-exist, inseparably. In any light, man’s further task is Jovian. That is to learn how best to live with these powerful creatures of his mind, how to give their fecundity a law and their functions a rhythm, how not to employ them in error against himself—since he cannot live without them. _Each, pott 8vo, 2/6 net_ _Occasionally illustrated_ TO-DAY AND TO-MORROW This series of books, by some of the most distinguished English thinkers, scientists, philosophers, doctors, critics, and artists, was at once recognized as a noteworthy event. Written from various points of view, one book frequently opposing the argument of another, they provide the reader with a stimulating survey of the most modern thought in many departments of life. Several volumes are devoted to the future trend of Civilization, conceived as a whole; while others deal with particular provinces, and cover the future of Woman, War, Population, Clothes, Wireless, Morals, Drama, Poetry, Art, Sex, Law, etc. It is interesting to see in these neat little volumes, issued at a low price, the revival of a form of literature, the Pamphlet, which has been in disuse for 200 years. _Published by_ KEGAN PAUL, TRENCH, TRUBNER & CO., LTD.
