RATIONALISM BASED ON DARWINISM 27 



of the Rationalists and Haeckel. It is they who go out 

 of their way to deny the existence of any scientific proof 

 of a God, of freedom and of immortality ; because these 

 things cannot be brought within the range of observation 

 and experiment. 



Moreover, as Haeckel and others avowedly base their 

 Materialism on Darwinism, I cannot avoid discussing 

 this latter subject on the present occasion. 



In order, however, to preserve more continuity in 

 what is intended to be apologetic, I propose relegating 

 my purely scientific discussion of Darwinism to an 

 appendix. 



If the reader prefer to do so, he might read that 

 appendix at this point of the argument with advantage.
