Civilized people feel a loneliness and even an extreme melancholia in the jungle of the mind that may make stillness a terrifying experience, but we can pass through this barrier if we will learn to understand it. Then we would discover, as the Indians did long ago, that to stand in solitude on a mountain top at sunrise or sunset, or by a waterfall in some hidden canyon of ethereal beauty, and to absorb this majesty with utter peace and awe, in which the soul merges with creation, and self is forgotten, is to become one with a joy and happiness so tremendous that no mere earthly pleasure can compare.
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.
