CONSCIOUSNESS AS A VITAL FUNCTION 311 



they are no more "non-physical entities" than are any 

 other bodily functions. 



If mind is a function of body, as most biologists 

 seem to beheve, then surely the recognition of mental 

 phenomena is not mysticism, nor is there any justi- 

 fication for ignoring these functions in a scientific 

 analysis of human behavior. Until we know more 

 about the relations of mental and physiological 

 phenomena it would seem to be sound scientific meth- 

 od as well as sound common sense to observe the 

 mental phenomena by the one method which at pres- 

 ent gives us fairly trustworthy (though admittedly in- 

 complete) information about them, namely, intro- 

 spective experience.
