Nature gives to every time and season some beauties of its own; and from morning to night, as from the cradle to the grave, is a succession of changes so gentle and easy we can scarcely mark their progress . . .
Without faith that it is possible to render reality understandable by means of our theoretical constructs, without faith in an inner harmony of the world, there could be no science. This faith is and always will be the basic motivation behind every creative scientific idea. All our endeavors, all the dramatic conflicts between old and new ideas are supported by the eternal desire for knowledge, the unshakeable faith in cosmic harmony which becomes stronger the more difficulties loom before us.
