EVOLUTION AND HUMAN DESTINY 



SO developed might well provide the basis for an "uni- 

 versalist" outlook arrived at by means of a scientific 

 approach. 



The reader who is a "stickler" for quantitative data, 

 as well as the strict adherent of formal logic, will find 

 fault with the manner in which the material in this 

 book is presented. Wide use is admittedly made of 

 analogy in order to show the essential continuity of 

 the evolutionary process as it takes place on its various 

 levels. Use of analogy, while generally not permissible 

 according to the rules of formal logic, however appears 

 justified in this presentation. Without its use, there 

 would be serious difficulties in the proper evaluation 

 of the inter-relationships of the phenomena discussed. 

 The important thing appears to be the establishment 

 of a causal relationship which is due to inherent prin- 

 ciple, and which welds the situations cited into a uni- 

 fied structure. Analogy, then, becomes an illustrative 

 device rather than an element of proof in a formalistic 

 presentation. 



The evolution of intelligent life, which has barely 

 begun with the emergence of man, can lead him to- 

 wards a future in which his present degree of control 

 over environment and his understanding of nature will 

 look puny in retrospect. Yet whether the road of hu- 

 man development will lead steadily upward, or 

 whether it will be interrupted by severe setbacks with 

 all the attendant sufferings for mankind, depends not
