As we stand and gaze at the movements of the airplane, or contemplate its rapid flight from ocean to ocean and from land to land around the world, we are impressed with this great wonder of the age, the great achievement of the inventive power of man. But what of the gain to humanity? If it is possible to transport the mails from New York to San Francisco in sixteen hours instead of in five days, is there advantage in that except the quickening process of transportation and life? Is it not worth while to inquire what the man at the other end of the line is going to do by having his mail four days ahead? He will hurry up somebody else and somebody else will hurry the next one, and we only increase the rapidity of motion. Does it really give us more time for leisure, and if so, are we using that leisure time in the development of our reflective intellectual powers or our spiritual life? It is easier to see improvement in the case of the radio, whereby songs and lectures can be broadcast all over the earth, and the {21} community of life and the community of interest are developed thereby, and, also, the leisure hours are devoted to a contemplation of high ideals, of beautiful music, of noble thoughts. We do recognize a modicum of progress out of the great whirring, rapid changes in transportation and creative industry; but let us not be deceived by substituting change for progress, or making the two identical. Thus human progress is something more than achievement, and it is something more than the exhibition of tools. It is determined by the use of the tools and involves betterment of the human race. Hence, all the products of social heredity, of language, of science, of religion, of art, and of government are progressive in proportion as they are successfully used for individual and social betterment. For if government is used to enslave people, or science to destroy them, or religion to stifle them, there can be no progress.
