Earth, stars, and the vastness of space; yesterday, today and tomorrow; and the endlessly increasing knowledge of the relation of forces, present an illimitable universe of numberless phenomena. Only in general outline can the universe be understood. In its infinite variety of expression, it wholly transcends the human mind... In the midst of this complexity man finds himself. As he progresses from childhood to manhood, and his slumbering faculties are awakened, he becomes more fully aware of the vastness of his universe and of the futility of hoping to understand it in detail. Nevertheless, conscious man cannot endure confusion. Out of the universal mystery he must draw at least the general, controlling laws that proclaim order in the apparent chaos; and especially is he driven, by his inborn and unalterable nature, to know if possible his own place in the system of existing things.
