14 THE WHENCE AND THE WHITHER OF MAN

 The very slightest favorable variation may make all the 

 difference between life and sure death. And yet these 

 indefinitely slight variations continued and aggregated 

 through ages would foot up an immense total diver- 

 gence. The chalk cliffs of England have been built up 

 of microscopic shells. 



I have tried to give you very briefly a sketch of the

 But you should all read that marvel of patience, indus- 

 try, clear insight, close reasoning, and grand honesty, 

 the " Origin of Species." I have no time to give the

 and it alone, furnishes an explanation for the facts 

 which they discover in their daily work. And this is 

 the strongest proof of the truth of any accepted theory. 



Inasmuch as it is accepted by all scientists and 

 largely by the public, it is certainly worth your while 

 to know whether it has any bearing on the great moral 

 and religious questions which you are considering. 

 And in these lectures I shall take for granted, what 

 some scientists still doubt, that man also is a product

 the so-called " lower animals." 



Now if the theory of evolution be true, and really
