So simple and straightforward is the road to travel, when we sincerely want to become true men of the world, that the expansion of heart and mind resulting from a steady walking upon this road must seem impossible to worldly men. And yet the narrowness of worldly men is in its essence similar to the narrowness of the dwellers in a small, gossiping country town. The worldly men have more superficial knowledge than the inhabitants of the country town, but they do not necessarily have any stronger grasp on the world-wide principles of human nature. Worldliness is the love of ease and the pride of life upon a low plane of commonplace existence, but a true knowledge of the world requires a higher elevation. The ascent of narrow paths and steep inclines leads to the mountain top; thence the outlook is wide, and the heights and depths of the landscape take their proper places in their true relation to each other. The single-minded drudgery and toil which produces character leads also to the wisdom of the seer. Only from the point of view of unselfish love and truth can we get a well-balanced and extended view of the heights and depths and commonplaces of the world. We have seen that a man, to know the world, must know and understand its individuals and types. We have seen that it is out of the question to understand other individuals, so long as we are clogged by our own selfishness or prejudice. We know that, to understand the point of view of another person, we must be clear, open-minded, and well grounded in true principles. We cannot understand another person's point of view truly when we are swayed and blinded by its influence, so that it sweeps us off our feet and takes possession of us in spite of ourselves. We must have true standards to judge others by, and those must be standards which we have tried and proved, over and over, for ourselves. At once the most interesting and the most profitable character-study in the world is the life of the one man whose life was consistently faithful to a standard which was universally true and all His own, and that standard He has given us for ours. Many of us fail in our interpretation of it, but, if we work diligently to try it and to prove it, and are openly willing and glad to acknowledge whenever we have misinterpreted it, we shall be steadily enlightened as to its true meaning. The delight of applying the laws of science and of seeing them work, the positive joy of watching the certain result of a well-managed scientific experiment is known to many a chemist or electrician. But the joy of testing the practical working of spiritual laws should be deeper, and more quiet, and more expanding than all other delights; for the spiritual law, if it exists at all, must underlie all material law.
