PROGRESS SHOWN IN EVOLUTION 



to think scientifically to suspend judgment on such questions 

 in the absence of evidence. 



What is definitely true is that the forces ivlylch xve can 

 actually detect operating in the evolution of plants and lower 

 animals are automatic and non-conscious; whereas those 

 operating on the human level, as we can again obviously 

 verify for ourselves, are in part conscious and include ideals 

 of truth, beauty, and morality. We may even say that the 

 forces of evolution conspire to act as "a power, not ourselves, 

 which makes for righteousness." 



Our business on this planet, then, is not to worry our 

 heads about the possible forces which jnay exist behind those 

 which we know, but to strive to mould the known material 

 forces of dead and living matter in accord with the spiritual 

 ideals of value which we possess.

"Is it not the most sublime, the most stimulating conception that has 

 ever entered human thought, this conception of progress, this new idea 

 absolutely unknown in ancient times, a progress of which we are a part, 

 and in which we are ourselves consciously playing a role of supreme 

 importance?" — Robert Millikan. 



"I do not know what I may appear to the world, but to myself I seem 

 to have been only like a boy playing on the seashore and diverting myself 

 now and then finding a smoother pebble or a prettier shell than ordinary, 

 while the great ocean of truth lay all undiscovered before me." — Sir Isaac 

 Newton.
