The whirring machine is not a sin against life but rather a part of its larger fulfilment. For man cannot improve his intelligence without inventing machines. Ascetics, mystics, and sentimentalists who complain that the machine has maimed and killed should also remember that it has served and saved. And when the same people mourn over the lost Arcadian happiness of primitive mankind they might remember that men who lived in frequent fear of wild beasts and hostile tribes could not have been ideally happy.
