Factors in Man's Emergence 201 



his speech, his reason, his morality, his personality. 

 But we must be patient, and when we speak of speech, 

 reason, morality, and personality, we must remember 

 Primitive Man and the least evolved human races of 

 to-day. Man cannot ignore his poor relations — and 

 there is little reason why he should be more ashamed 

 of them than of himself. It is impossible, we think, to 

 split man into two — bodily frame and personality — 

 and the evidence is cumulative in support of the con- 

 clusion that man is solidary with the rest of creation. 



§3. Factors in Marts Origin. 



Darwin stated the case for regarding man as affili- 

 ated to the Primates, but he did more. He made con- 

 tributions to the problem, still before us, of picturing 

 the factors that may have operated in man's emer- 

 gence. What were these factors? There were new 

 departures or variations — still an abundant crop; 

 there were processes of sifting or selection which were 

 prompted by love as well as by hunger, and winnowed 

 a capacity for mutual aid as well as the strenuous 

 "will to live" ; there were conditions of isolation that 

 favored endogamy (or in-breeding) and of dispersal 

 that favored exogamy (or out-breeding) ; and there 

 were of course the conditions of hereditary entail- 

 ment. The factors in man's emergence and ascent 

 remain very obscure, but to use this frank admission 

 of ignorance as an argument against the general idea 

 of the Descent of Man is bad thinking. It is uncon- 

 scious dishonesty of the intellect.
