Frank W. Blackmar,
History of Human Society
“ 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. ”
