 fresh quests ; at first, no doubt, and properly, 

 armed cap-a-pie with brass instruments 

 and copper wires. Faithful to his physico-

 times, he plots curves, he again reassures him-

 plain folk, that beyond the often measurable 

 bio-psychoses of the psychological laboratory 

 there are psycho-bioses, often immeasurable, 

 in the greater world-laboratory of life. After 

 this initiation, a new and before-unsus- 

 pected thought-world opens; and within this 

 begins the real controversy, of reconciling the 

 claims and methods of orderly science with 

 these deepest, yet most incontestable, data 

 of experience. In such ways the enduring 

 contrast, or at least the bias, of the mechan- 

 istic and the vitalistic training and tempera-
