…when thou lookest at the orderly pattern of kingdoms, cities and villages, with the attractiveness of their adornments, the freshness of their natural resources, the refinement of their appliances, the ease of their means of travel, the extent of knowledge available about the world of nature, the great inventions, the colossal enterprises, the noble discoveries and scientific researches, thou wouldst conclude that civilization conduceth to the happiness and the progress of the human world. Yet shouldst thou turn thine eye to the discovery of destructive and infernal machines, to the development of forces of demolition and the invention of fiery implements, which uproot the tree of life, it would become evident and manifest unto thee that civilization is conjoined with barbarism. Progress and barbarism go hand in hand, unless material civilization be confirmed by Divine Guidance, by the revelations of the All-Merciful and by godly virtues, and be reinforced by spiritual conduct, by the ideals of the Kingdom and by the outpourings of the Realm of Might.
