The engine tearing through the disembowelled mountain, the iron and steel houses towering against a polluted sky, the huge cylinders generating electricity and gas, the network of wires cutting across the poisoned air, the overgrown cities spreading like scurvy, devouring every green thing like locusts; haste instead of leisure, Neurasthenia instead of health, mania instead of sanity, egotism and terror instead of courage and generosity, these are the gifts which the modern mind creates for the world. It can chemically imitate every kind of food and drink, it can artificially produce every form of disease and suffering, it can carry death in a needle and annihilation in an odour, it can cross an ocean in five days, it can imprison the human voice in a box, it can make a dead man speak from a paper cylinder, it can transmit thoughts over hundreds of miles of wire, it can turn a handle and discharge scores of death-dealing tubes at one moment as easily as a child can play a tune on a barrel organ, it can pack death and horror up in a small tin case which has served for sardines or potted herrings, and leave it on a window-sill, and cause by it towers to fall, and palaces to crumble, and flames to upleap to heaven, and living men to change to calcined corpses; all this it can do, and much more. But it cannot give back to the earth, or to the soul, 'the sweet wild freshness of morning.' And when all is said of its great inventions and their marvels and mysteries, are they more marvellous or more mysterious than the changes of chrysalis and caterpillar and butterfly, or the rise of the giant oak from the tiny acorn, or the flight of swallow and nightingale over ocean and continent? Man has created for himself in the iron beast a greater tyrant than any Nero or Caligula. And what is the human child of the iron beast, what is the typical, notable, most conspicuous creation of the iron beast's epoch?
