FUNCTION AND ENVIRONMENT 



the description of all developmental stages 

 from the amoeba up; and those move most 

 surely among the altitudes who have most 

 carefully explored the depths in which the 

 highest human powers originate. Emotions 

 are best studied in their outward expressions 

 of gesture, will is investigated by the study 

 of behaviour, intelligence by massed in- 

 stances of sagacity, and not by analysis 

 under old rubrics." 



With example like this of Darwin's, and 

 guidance like this of Stanley Hall's, no 

 biological brother need fear to enter the 

 school of psychology, as we ourselves have 

 done, albeit also tardily. From its many 

 and ever-widening outlooks new views ap- 

 pear; on one side, perhaps, a glimpse of how 

 to clear up the vagueness of current vitalism, 

 and in any case many ways of mellowing the 

 crudeness of current mechanism.
