120 GRAND STRATEGY OF EVOLUTION 



are improvements, because they are more cooperative, 

 and more constructive in their effects. They cannot 

 come into being, or at most but temporarily, if they 

 are destructive to the internal organization of life; and 

 they cannot endure without still further improvements, 

 keeping pace with the progress of the external world, 

 which itself moves onward, in its own way, with irre- 

 sistible momentum. 



The long story of these manifold adjustments and 

 devices is partly told by those branches of science, fa- 

 miliarly known as natural history, and by the more 

 modern science of cecology. 



IV. The Federal Administration of Life 



When these two administrative systems are approxi- 

 mately balanced, a definite rate of growth or, exchange, 

 ensues, constituting for the time being what is called 

 fitness, or adaptation for existence. 



But this rate is never uniform, in whole or in part, 

 because the internal and external improvements are 

 never of equal creative value; because other condi- 

 tions, within and without, are constantly changing, and 

 these changes are not necessarily dependent on one an- 

 other. 



There must be some ways and means, therefore, of 

 restoring the cooperative balance between the inner 

 and outer life whenever it is unduly upset. For lack 

 of a better term, we shall call these ways and means 

 the federal administration of life. 



The two systems control each other in something 

 like the following manner: As we have already indi- 

 cated, better internal administration produces either
