vi PREFACE. 



Then as to the natural theological questions which 

 (owing to circumstances needless now to be recalled 

 or explained) are here throughout brought into w^hat 

 most naturalists, and some other readers, may deem 

 undue prominence, there are many who may be inter- 

 ested to know how these increasingly prevalent views 

 and their tendencies are regarded by one who is scien- 

 tifically, and in his own fashion, a Darwinian, philo- 

 sophically a convinced theist, and religiously an ac- 

 ceptor of the " creed commonly called the Kicene," 

 as the exponent of the Christian faith. 



" Truth emerges sooner from error than from con- 

 fusion," says Bacon ; and clearer views than com- 

 monly prevail upon the points at issue regarding 

 " religion and science " are still sufficiently needed to 

 justify these endeavors.
