To each set of conditionally stringent constraints there corresponds a posi- 

 tive, definite, scalar measure of nonuniformity manifested in experience by the 

 internal forces. The relaxation of such constraints increases uniformity, and 

 the selection among a possible set of conditionally stringent constraints is made 

 to maximize global uniformity in adherence with the principle of maximum uni- 

 formity, as amplified in the following section. The universal constants embrace 

 constancy and process and thus both uniformity and nonuniformity. This is the 

 synthesis they reveal in the elementary processes. 



The process of reducing the nonuniform ities in nature's space -time mani- 

 fold is here envisaged to be the ultimate aspect of all adaptive phenomena in 

 nature. Evolution becomes then a word to label this universal adaptive process. 

 An aspect of evolution that is both essential and universal^ is force, and its na- 

 ture we evidently no more grasp in physics than in biology. 



HIERARCHIES OF UNIFORMITY 



We can interpret the resultant force posited to a nonfree body, as the vector 

 sum of all nonuniform connections which exist between the body and the uni- 

 verse. Each force individually contributing to this sum, posits to the body a 

 nonuniform aspect of the universe. In cases when the vector sum of these indi- 

 vidually applied forces vanishes, we previously considered the body as free but 

 not disjoined from the universe. Here the individual forces may be envisaged 

 as existing in mirror-symmetric pairs, the forces in each pair being conse- 

 quently equal in magnitude. However, according to the usual laws of classical 

 mechanics, the definition of a free body does not demand that the magnitudes of 

 the individually applied forces be uniform for all pairs. 



From these considerations we learn that there exist hierarchies of free 

 bodies, all of which are equivalent according to the known laws of classical me- 

 chanics and which are therefore not discernible nor identifiable by these laws. 

 The hierarchies of free bodies may be identified and thus distinguished by the 

 degree either of uniformity or nonuniformity of the magnitudes of the individual
