THE FUNCTION AND TEST OF DEFINITION 

 AND METHOD IN PSYCHOLOGY^ 



Amid all of the discussion current in the 

 last few years among psychologists the un- 

 prejudiced outside observer might think 

 that we were a body of men professing to 

 develop and teach a science who did not 

 know what that science was to deal with 

 and without any idea or with too many 

 ideas as to the methods that should be fol- 

 lowed in undertaking to develop our knowl- 

 edge of the unknown or undetermined sub- 

 ject-matter. Psychology is at once the 

 science of mind, the science of conscious- 

 ness, the science of experience, the science 

 of behavior. Psychology must be studied 

 only by careful watching of the processes 

 of the individual, by the individual him- 

 self; one who does not proceed in this way 

 is no psychologist, no matter how valuable 

 his work may be as physiology or biology 

 or sociology. On the other hand, we are 

 assured by just as devoted and well-recog- 

 nized psychologists that psychology must 

 deal only with the responses of the indi- 

 vidual, with what can be seen from the 

 outside, and that what the first man deals 

 with really has no existence, or at best is 

 entirely irrelevant to the responses, to 

 anything that is of scientific interest. If 

 we are to be taken at our own valuation we 

 are either altogether unfit to carry on the 

 task we have set ourselves or entirely un- 

 prepared for it. 



As a matter of fact I presume this comes 

 from the youth of the science, at least from 

 taking a definition and formal statements
