INTRODUCTION 



doubt that Fiske himself was always disposed 

 to do justice to the historical influence of indi- 

 viduality. This chapter xx. is therefore an im- 

 portant expression of Fiske's personal judgment 

 of issues that were, for him, always prominent. 

 25. Chapter xxi., "Genesis of Man, Intel- 

 lectually," brings Fiske again nearer to the ex- 

 pository attitude. Only now he is once more 

 dealing with a problem common to all the evo- 

 lutionists, and the most important matter that 

 appears in the chapter, bearing upon the solu- 

 tion of the problem defined in the title, is de- 

 rived from Wallace rather than from Spencer. 

 The evolution of man depended upon the pro- 

 cess of natural selection in which power of brain 

 was preferred to strength of muscle, and to other 

 physical advantages. This power of brain was 

 itself due at each step to variation, as well as to 

 direct adaptation. In dealing with the problem, 

 Fiske accordingly emphasizes the " Darwinian 

 factor " of evolution. What momentous con- 

 sequences for man's moral evolution, and for 

 Fiske's own later teleological view of the evo- 

 lutionary processs, our author founded upon 

 these considerations of Wallace, we shall here- 

 after see.
