286 GRAND STRATEGY OF EVOLUTION 



social growth at once reveals four main categories of 

 phenomena whose constructive relations to one another 

 must be considered, (i) Nature-action, or the cosmic 

 action system itself, as expressed in the growth, or crea- 

 tion, of physical and organic bodies. (2) Man's reac- 

 tions, as a purely animal organism, to the cosmic sys- 

 tem. (3) His mental imagery of nature action. (4) 

 His conduct in reference to his outer world, as influ 

 enced by his imagery, or by his so-called intelligence. 

 The first two categories we have considered in the 

 preceding chapters. 



As man's mental imagery is a prime creative factor 

 in the newer phases of cosmic evolution that we call so- 

 cial life, giving man a new footing in the world differ- 

 ent from all the other products of nature, it is necessary 

 for us to consider how this mental imagery has grown 

 up in man, and how it has influenced his conduct. In 

 this way we may, perhaps, better understand the ar- 

 chitectural relations between these great action sys- 

 tems, for it is evident that, at least in some measure and 

 in some way, they must become more rightly fitted to 

 one another before they can act more cooperatively, or 

 profitably, or before they can become progressively 

 creative and saving agencies. As an intelligent animal, 

 man's life and growth is contingent on the Tightness 

 both of his mental imagery and his conduct, or upon the 

 maintenance of profitable relations between his mental 

 imagery, his conduct, and his outer world. 



Sometime, perhaps, the evolutionist may be able to 

 trace in broad perspective, the growth of man's mental 

 life into those more specific systems of mental imagery 

 called religious, scientific, and philosophic thought, 

 and to trace their concomitant morphological expres-
