EVOLUTION AND THE IIIGIIEIl HUMAN LIFE 291 



beginnings of time? Would any one contend that the 

 creeds of Protestantism have remained unchan^^cd even 

 during the past twenty years ? Like all d('i)arlrnent,s of 

 human belief and knowledge, religious concepts have 

 obviously altered in natural adjustment Lu changing 

 times and to advancing conditions of human intellect; 

 and the question turns to the mode by which they have 

 been modified, to see whether natural causes of evolu-

 couched in very general terms. If we define it as the 

 attitude and reaction of a human being conditioned by 

 his know^ledge of the immediate materials and his con-

 attitudes toward theirworlds of animals lower than man.
