LIFE AND MIND 



ers) ; thus leaving to psychology all other ad- 

 justments of inner to outer actions.** " The 

 moment we rose to a type of creature which 

 adjusts certain organic relations to relations of 

 which both terms are not presented to its sur- 

 face, we passed into adjustments of the psycho- 

 logical order. As soon as there exists a rudi- 

 mentary eye capable of receiving an impression 

 from a moving object about to strike the organ- 

 ism, and on rendering it possible for the organ- 

 ism to make some adapted movement, there is 

 shown the dawn of actions which we distinguish 

 as intelligent. As soon as the organism, feebly 

 sensitive to ajar or vibration propagated through 

 its medium, contracts itself so as to be in less 

 danger from the adjacent source" of disturbance, 

 we perceive a nascent form of the life classed as 

 psychical. That is to say, whenever the corre- 

 spondence exhibits some extension in space or 

 in time, some increase of speciality or complex- 

 ity, we find we have crossed the boundary be- 

 tween physical life and psychical life." ^
