 duct and there is much of value that will inevitably be 

 lost. 



Teachers of psychology for more than a genera- 

 tion past have been accustomed to include in their

 these matters are significant for introspective psy- 

 chologists only in so far as it is recognized that intro-

 they are irrelevant. 



If mind as we know it phenomenally, that is, as 

 an awareness process, is not knit into the sequence of 

 living as a natural event, if mind is epiphenomenon, 

 parallel phenomenon, by-product, or any other sort of 

 pseudophenomenon and not a natural process inte-

 examined only introspectively have any place in 

 natural science. 



On the other hand, if that experience which we 

 objectify and that experience which we do not ob-

 ground on which introspective psychology and ob-
