As a matter of fact, man has always been curious about his world. Yet before he hit upon the proper methods of investigation, he could only guess and dream about it, under the sway of hopes and fears which too easily threw themselves like gigantic shadows before him. The fire of his untrained intelligence was feeble and unpenetrating and, so, distorted the world which it {4} dimly revealed. The result was what must be called the older religious view of the world--a view which saw personal and super-personal agency at the heart of things. This primitive interpretation of the world we shall be led to criticize, but, in so doing, we shall be the servants of truth and of a more adult spirituality. It is not surprising that the patiently acquired knowledge, obtained by science, philosophy and a matured human wisdom, has been found to conflict with the first interpretation of the world. The recognition of this conflict dates back now some centuries--the warfare between science and religion also has its history--but each generation has seen the addition made of some new element to the clash which is leading man to a new view of the world. What is striking about the present situation is the increase of the positive elements in the outlook which is forming in men's minds. In the past, the traditionalist had some justification in speaking of the opposed ideas as largely negative. What positive doctrine there was in the physical science which theology had to meet, to its discomfort, had only an indirect bearing upon life. But the nineteenth century was the witness of a distinct revolution in this regard. I do not refer merely to the fact that the idea of evolution was applied to man. That was prophetic and strategic rather than revolutionary. It symbolized the passage of science from the periphery to the center, from the outlying regions of the universe to man's very self. All the time, however, a new perspective had been arising in man's interests and values. The possibilities and needs of this life were replacing the dream of another life in {5} another world. A busy concern with the things of this world was everywhere evident. Man was seeking to master his environment.
