3 o6 GRAND STRATEGY OF EVOLUTION 



self expression increased, he attempted to formulate 

 more exactly and permanently these constructive and 

 destructive ways into both more general and more spe- 

 cific rules, or laws, of social conduct. Obedience to 

 his laws he then counted a virtue, called it morality, 

 and guarded and cherished it in others as a useful prop- 

 erty to himself. 



Written social laws are therefore but verbal formu- 

 las to express man's mental imagery of right and wrong 

 within a limited field o nature-action. Because they 

 are so limited, they are not immutable. In fact they 

 must be perpetually remodelled the better to adapt 

 them to the new conditions created by social growth, 

 to the growth of man's intelligence, to the increase of 

 his properties, to larger numbers, and to the ability 

 of the masses to understand more elemental, more com- 

 prehensive truths. 



We have seen that creative power in the purely 

 physical and organic worlds depends on the coopera- 

 tive action of various architectural agents,, on their en- 

 during physical or chemical attributes, on their distri- 

 bution in time and space, and on the way in which 

 each one moulds and directs the other into constructive 

 Tightness. 



In human social life these same factors still play 

 their necessary parts in the creation and preservation 

 of the individual man and his properties. But beyond 

 and above this substratum of unconscious physical and 

 organic cooperation, intelligence enters as a new se- 

 lective and directive agent, moulding human beings, 

 as intelligent individuals endowed with a new con- 

 structive attribute, or a will of their own, into coopera- 

 tive action.
