24 THE METHOD OF DARWIN. 



remain the clearest model in the biological 

 world for the study of applied lo^kT^) 



There are two ways open for the logical 

 study of Darwin's works: one in which the 

 methods of handling material and the differ- 

 ent logical processes would be illustrated by 

 examples from different parts of his works; 

 and the other in which each of his investiga- 

 tions would be studied apart from the rest for 

 the purpose of noting the part which induc- 

 tion, deduction, analogy, and verification play 

 in producing the results. The former was 

 chosen, because in that way the best examples 

 of each of the logical processes could be 

 brought together in the smallest compass, 

 while the latter would require an elaborate 

 summary of the works themselves before their 

 logic could be discussed. No epitome, much 

 less selected examples, can be made a substi- 

 tute for a logical study of the works them- 

 selves; it can at most serve as a guide to 

 further study.
