EVOLUTION OF SOCIAL STRUCTURES 855 



ideal human institutions that a progressive age demands. A con- 

 dition of social statics may thus be converted into one of social 

 dynamics. All social structures taken together constitute the social 

 order. The problem is to inaugurate a condition of social progress. 

 This cannot be done by disturbing the social order. Order is the 

 condition to progress, and progress consists in setting up dynamic 

 activities in the social structures themselves. A structure repre- 

 sents a state of equilibrium, but it is never a perfect equilibrium, 

 and the conversion of this partial equilibrium into a moving equi- 

 librium, provided it moves in the right direction, is social progress.
