PREFACE vii 



Evolution, published in 1906. But the contents of 

 Catholic papers and of scientific works written by 

 Catholic authors do not, as a rule, penetrate to 

 those who have been most influenced by Haeckel s 

 lectures in Berlin, or if they reach them at all, it is 

 in a distorted form. Therefore I deemed it very 

 important to give a course of lectures in Berlin itself 

 on the same subject. 



The first suggestion that I should give such a 

 course was made to me on July 21st, 1906, by the 

 managers of the Sachs concerts, who had organised 

 Haeckel s lectures in the previous year. I did not, 

 however, fall in with the proposal, being anxious to 

 avoid all appearance of provoking a discussion, and 

 the invitation, which I eventually accepted, pro 

 ceeded from another quarter, and was framed in 

 such a way as to guarantee the scientific character 

 of the lectures. 



On January 25th, 1907, the syllabus of my lectures 

 appeared. They were delivered in the upper Hall of 

 the Philharmonic. In this syllabus the following 

 points were mentioned as topics for discussion : 



First Evening (February 13th). The Doc 

 trine of Evolution considered as a Scientific 

 Hypothesis and Theory (with lantern 

 slides). 



Second Evening (February 14th). Theistic and 

 Atheistic Doctrines of Evolution Evolution 

 and Darwinism.
