as a "Mutation" Possible factors in the early evolution 

 of Man Repugnance to the scientific interpretation, 

 partly due to misunderstanding, partly aesthetic, partly 

 ethical The value of a product is independent of its re- 

 mote origin Man is not a masterpiece "accidentally pro- 

 duced"; Man forms a new departure in the gradual un- 

 folding of Nature's predestined scheme The evolutionist 

 interpretation is not necessarily naturalistic A comparison 

 and contrast of animal behavior and human conduct As 

 regards animals, we may speak of intelligence, but not of 

 reason; of words, but not of language; of behavior, but 

 not of conduct In what sense, if any, can it be said that 

 human conduct has evolved from animal behaviour ? The 

 cerebral mutation was the Rubicon Increasing cerebral 

 complexity made a higher intelligence possible, language 

 and conscience date from that dawn Certain raw ma- 

 terials of conduct in the form of primary impulses were 

 inherited from pre-human ancestry, but Man, who reasoned, 

 spoke, and controlled his behaviour in relation to more than 

 merely perceptual ends, raised these to a higher power 

 Huxley's thesis as regards the contrast between human 

 and cosmic evolution Reasons for dissenting from Hux- 

 ley's conclusion Value of the evolutionary conception of 

 Man It clears things up, it suggests effort, it is hope- 

 inspiring, it makes the whole cosmic process more intel- 

 ligible Retrospect on the riddles which our brief survey 

 has disclosed They bring us back to the wonder with 

 which we began The riddles of things as they are We 

 formulate sequences in terms which are not self-explan- 

 atory The riddles of the history of things Riddles as to 

 origins The riddle of the death of the Earth The riddle 

 of suffering The philosophical and the scientific outlook 

 The limitations of science Anima animans Meaning 

 of the title "The Bible of Nature."
