system (of the theory). "The relation between 

 the physical and psychic elements of a sen- 

 sation," which, as Wolfgang Pauli says,^ Mach 

 recognized as early as 1865, finds its statement in 

 the terms that describe the interrelations of the two 

 systems of the dual-system, as which I describe the 

 organism. The two systems, the qualities of both, 

 and their interrelations, are conceived in terms of 

 atomic physics. It is plain that the details of the 

 interrelations and the interacting of the two sys- 

 tems, can be stated only mathematically. Since as 

 Jaques Loeb set forth (after saying that "the un- 

 raveling of the mechanism of associative memory is 

 the great discovery to be made in the field of brain- 

 physiology and psychology"): "It is evident that 

 this mechanism cannot be unraveled by histological 

 methods, or by operations on the brain, or by 

 measuring reaction times. "^ Atomic physics sup- 

 plies sufficient exact data to enable satisfactory 

 mathematical work on these problems. (But see 

 p. 267.) And — to quote Loeb again: "It is com 

 paratively easy for the physicist to give his data the 

 form of a mathematical law."^ 



The theory for the first time shows the problems 

 of "brain capacity" and of psychic powers to be
