HUXLEY AND NATURAL SELECTION. 135 



Its value for Huxley was that it was " incomparably 

 more probable than the creation hypothesis " ; that 

 it was " a hypothesis respecting the origin of known 

 organic forms, which assumed the operation of no 

 causes but such as could be proved to be actually at

 of natural facts, until they were, so to speak, thrust 

 under our noses, what force remained in the dilemma

 that the links of natural causation were hidden from 

 our purblind eyes, than that natural causation should 

 be incompetent to produce all the phenomena 

 of nature." 



Therefore, " the only rational course for those who
