THE ENERGIES OF MEN' 

 We habitually hear much nowadays of 

 the difference between structural and func- 

 tional psychology. I am not sure that I 

 understand the difference, but it probably 

 has something to do with what I have 

 privately been accustomed to distinguish 

 as the analytical and the clinical points of 

 view in psychological observation. Pro- 

 fessor Sanford, in a recently published 

 ' Sketch of a Beginner's Course in Psy- 

 chology,' recommended 'the physician's 

 attitude' in that subject as the thing the 

 teacher should first of all try to impart to 

 the pupil. I fancy that few of you can 

 have read Professor Pierre Janet's mas- 

 terly works in mental pathology without 

 being struck by the little use he makes of 

 the machinery usually relied on by psy- 

 chologists, and by his own reliance on con- 

 ceptions which in the laboratories and in 

 scientific publications we never hear of 

 at all.

 and fall of thresholds, impulses and in-
