vi Preface 



on work performed by definite parts of the 

 brain; consequently, education has not only to 

 deal with the training of something immaterial 

 which we call mind or consciousness, but has 

 first and foremost to deal with the proper de- 

 velopment of the nervous substance of that part 

 of the brain the orderly working of which is 

 essential for the occurrence of instinctive, and 

 intellectual phenomena. In the majority of 

 healthy children this purpose can be attained by 

 means of the appropriate exercise of their eyes, 

 ears, and other sensory organs; for, as we ex- 

 plain, energy derived from this source stimu- 

 lates and develops the living substance of those 

 parts of the brain directly concerned in the 

 elaboration of an individual's instinctive and 

 intellectual processes; we may thus hope to 

 lay the foundation on which to build up a 

 chaste, self-reliant character combined with a 

 clear and strong intellectual capacity.
