38 ONTOGENESIS AND PHYLOGENESIS. 



We shall never be changed — We shall never know 

 it' 



It is this ' Ignorabimus' continues Haeckel, with 

 the unflinching confidence of a true Evolutionist — 

 shall I say the dogmatism and intolerance also ? — 

 which Professor Du Bois Raymond would interpose 

 as a barrier to the progressive development of 

 science, and thus aid the ' Church Militant ' in its 

 crusade against freedom of thought and truth, reason 

 and culture, development and progress ; — a war in 

 which Evolutionists, who are the Soldiers of Truth, 

 can have no better ally than Anthropogenesis ; for 

 the real history of man's origin Haeckel considers to 

 be the heavy artillery of the evolutionary army ! 



Such are the sentiments, Professor Haeckel 

 frankly lets us know, with which he enters on his 

 subject. 



1 Anthropogenesis ' Professor Haeckel treats 

 under the two distinct heads of Ontogenesis and 

 Phylogenesis : Ontogenesis, or the embryonic deve- 

 lopment of the individual man by ordinary generation 

 in the short period of 280 days ; and Phylogenesis, or 

 man's alleged descent by Evolution, in the course of 

 millions of years, from the lowest organisms, and in 

 the last instance from apes. 



Ontogenesis Evolutionists regard as a short and 

 I rapid recapitulation of Phylogenesis — the individual 

 [animal in the course of its development from the 

 IJovum to its complete form, passing rapidly through
