_Differences between the Actual Shape of Society and the Static One at Any One Time._--The actual shape of society at any one time is not the static model of that time; but it tends to conform to it, and in a very dynamic society is more nearly like it than it would be in one in which the forces of change are less active. With all the transforming influences to which American industrial society is subject, it to-day conforms more closely to a normal form than do the more conservative societies of Europe and far more closely than do the sluggish societies of Asia. A viscous liquid in a vessel may show a surface that is far from level; but a highly fluid substance will come nearly to a level, even though we shake the vessel containing it vigorously enough to create waves on the surface and currents throughout the whole mass. This is a fair representation of a society in a highly dynamic condition. Its very activities tend to bring it nearer to its static model than it would be if its constituent materials were not fluid and if it were never agitated. The static shape itself, though it is never completely copied in the actual shape of society, is for scientific purposes a reality. There are powerful influences tending to force the industrial organization at every point to conform to it. The level of the sea is a reality, though the motion of the waters never subsides sufficiently to make their surface accurately conform to it. As vigorously agitated, the water shows a surface that is nearer to the ideal level than would an ocean of mud, tar, or other sluggishly flowing stuff. The winds throw up waves a few feet high, but the fluidity keeps the general surface surprisingly level; and so civilized society, made as it is of fluid material kept in vigorous agitation, finds, as it were, its level easily. If in any year we could and should stop the dynamic disturbances, the economic society would assume the static shape which the conditions of that year called for as readily as the sea would find its normal level if winds and tides should completely cease. Static influences that draw society forever toward its natural form are always fundamental, and progress has no tendency to suppress them.
