i io GRAND STRATEGY OF EVOLUTION 



opment are quickly attained. Hence this onward 

 march of organized growth is divided into many un- 

 like stages; into epochs, eras, and periods; into units, 

 organs, systems and classes; and into longer, or shorter, 

 genetic series, such as embryonic, phyletic, and ortho- 

 genie, in accordance with the constructive value of 

 some particular improvement in service. Moreover the 

 development of every system must wait the passage 

 of stormy events, or the coming of their fruits. It 

 must wait for the growth of new parts; till the new 

 and the old are cooperatively adjusted to one another; 

 till the stronger are adequately served by the weak, 

 and the weak by the strong. 



Thus while the flow of creative processes is unin- 

 terrupted, the creative rate is modulated by various 

 creative phrases and cadences; breaking up into what 

 we call different kinds of living things, created at dif- 

 ferent times and places, endowed with unequal oppor- 

 tunities, and with unequal constructive values. 



X. Stability of Individual Life Essential to Social Life 



It is evident, therefore, that reunion and associative 

 growth, whatever the value, or nature, of the associated 

 units may be, cannot be definitely established until the 

 possibilities of cooperative improvements in these units 

 approaches its limitations, and their structures and 

 organization have acquired some measure of stability. 

 Conversely, no association can endure unless it is built 

 on a degree of stability, or integrity, in its constituent 

 units sufficient to insure continuity of associative co- 

 operation. 



Hence all growth and progress is concerned pri-
