_Progress Expresses Itself in a Variety of Ideals and Aims_.--Progress involves many lines of development. It may include biological development of the human race, the development of man, especially his growth of brain power. It may consider man's adaptation to environment under different phases of life. It may consider the efficiency of bodily structure. In a cultural sense, progress may refer to the products of the industrial arts, or to the development of fine arts, or the advancement of religious life and belief--in fact, to the mastery of the resources of nature and their service to mankind in whatever form they may appear or in whatever phase of life they may be expressed. Progress may also be indicated in the improvement in social order and in government, and also the increased opportunity of the individual to receive culture through the process of mutual aid. In fact, progress must be sought for in all phases of human activity. Whatever phase of progress is considered, its line of demarcation is carefully drawn in the process of change from the old to the new, but the results of these changes will be the indices of either progress or retardation. {22} _Progress of the Part and Progress of the Whole_.--An individual might through hereditary qualities have superior mental traits or physical powers. These also may receive specific development under favorable educational environment, but the inertia of the group or the race might render ineffective a salutary use of his powers. A man is sometimes elected mayor of a town and devotes his energies to municipal betterment. But he may be surrounded by corrupt politicians and promoters of enterprises who hedge his way at every turn. Also, in a similar way, a group or tribe may go forward, and yet the products of its endeavor be lost to the world. Thus a productiveness of the part may be exhibited without the progress of the race. The former moves with concrete limitations, the latter in sweeping, cycling changes; but the latter cannot exist without the former, because it is from the parts that the whole is created, and it is the generalization of the accumulated knowledge or activities of the parts that makes it possible for the whole to develop.
