124 SOCIAL EVOLUTION 



Gulf to Egypt, where there was most depth of country. 

 Just about this time the valley of the Nile and the 

 valley which we call Mesopotamia were formed by the 

 rivers; and out of the turmoil and struggle of tribes 

 for the fertile valleys came the first beginnings of 

 civilization. 



The story of evolution is a great aid to correct think- 

 ing. It may begin with stars which are a long way 

 off, but it leads to man and man's evolution. It 

 gives you a solid scientific ground for hope and trust 

 in man. No evolutionist can be a pessimist. The 

 human story is only just opening. Those million 

 years of early human development, of which I have 

 spoken, were only the prelude. Now we know more 

 or less where we are and what we are doing. Ac- 

 cording to the best estimates of mathematicians, 

 man will remain on this earth for something more 

 than ten million years yet. At the rate at which we 

 have gone for the last hundred years, this period of 

 time opens out a prospect of such happy developments 

 as are beyond the capacity of the liveliest imagina- 

 tion. We are the factors of evolution to-day. We 

 are the masters and the creators. Let us get the plan 

 right and forge ahead.
