42 THE EVOLUTION OF SCIENCE. 



and guided every step toward its present gigantic 

 attainments. 



But the doctrine of evolution has been invoked to 

 explain the progress of all things. It is claimed that de- 

 velopment is continuous. From inanimate matter through 

 living to sentient and reasoning beings, and thence 

 upward even into religion, philosophy and all else that 

 goes to make up civilization, it is claimed that there is 

 no break in the line of heredity. If this be so, then the 

 evolution of any one thing, as of science, must represent 

 the true character of the process in all its stages. And 

 if the evolution of science can be explained only by in- 

 voking the power of a principle which is superior to 

 science and independent of it, then is evolution nowhere 

 spontaneous. It must everywhere be determined by 

 something higher than the attributes of things. It is a 

 process which at every step must have been directed by 

 an independent and a supreme intelligence.
