94 GRAND STRATEGY OF EVOLUTION 



about: (i) by reducing the more available supplies; 

 (2) by making it more difficult for constructive ma- 

 terials to reach all the growing points in the larger 

 organism; (3) by making it more difficult to remove 

 waste, or encumbering, materials. (4) Some points, or 

 organs, must necessarily be more favorably situated 

 for this give and take than others, and they will grow 

 differently, or faster than the others. In this way, the 

 initial internal cooperative balance of the whole or- 

 ganism is sooner or later upset, and this organic un- 

 balancing produces a fourth check to growth. Growth, 

 therefore, in all kinds of growing things, however 

 great and inexhaustible the potential power of growth 

 may be, is inevitably checked by its own success. 

 Growth will go on, provided some improvement in 

 mutual services takes place, or "happens," or is found, 

 due either to betterments in the instruments of ex- 

 change, or to a better arrangement of them in time 

 and space. If not, disorganization increases, and death 

 or disintegration inevitably ensues. Growth may then 

 take a new start with somewhat different materials, or 

 under somewhat different conditions, and the whole 

 process may be approximately repeated, possibly with 

 better success than before. 



5. Development, or the Simultaneous Increase in 

 Volume, in Diversity, and Mutual Service. Thus no 

 conceivable method of growth can proceed in the same 

 manner, nor can it continue to produce the same re- 

 sults. With each increment in mass the modifying 

 effect of the whole on each constituent part is more 

 and more effective; and with each increment in vol- 

 ume, the distance from one extremity of the growing 

 body to the other, the differences in age between the
