106 THE STRUGGLE FOR EXISTENCE v

 a libel upon possibility. It is really only another 

 instance to be added to the many extant, of the 

 audacity of d priori speculators who, having 

 created God in their own image, find no difficulty 

 in assuming that the Almighty must have been

 sentient world is, on the whole, regulated by 

 principles of benevolence, does but ill stand the 

 test of impartial confrontation with the facts of 

 the case. No doubt it is quite true that sen

 contrivances directed towards the production of 

 pleasure or the avoidance of pain ; and it may be 

 proper to say that these are evidences of benevo

 say of the equally numerous arrangements, the no 

 less necessary result of which is the production 

 of pain, that they are evidences of malevolence ? 



If a vast amount of that which, in a piece of 

 human workmanship, we should call skill, is
