All that remained was the scientific specialist, who knew “more and more about less and less,” and the philosophical speculator, who knew less and less about more and more. The specialist put on blinders in order to shut out from his vision all the world but one little spot, to which he glued his nose. Perspective was lost. “Facts” replaced understanding; and knowledge, split into a thousand isolated fragments, no longer generated wisdom. Every science, and every branch of philosophy, developed a technical terminology intelligible only to its exclusive devotees; as men learned more about the world, they found themselves ever less capable of expressing to their educated fellow-men what it was that they had learned. The gap between life and knowledge grew wider and wider; those who governed could not understand those who thought, and those who wanted to know could not understand those who knew. In the midst of unprecedented learning popular ignorance flourished, and chose its exemplars to rule the great cities of the world; in the midst of sciences endowed and enthroned as never before, new religions were born every day, and old superstitions recaptured the ground they had lost. The common man found himself forced to choose between a scientific priesthood mumbling unintelligible pessimism, and a theological priesthood mumbling incredible hopes.
