"When U is recalled that the 9,200, 000, 000 cells in the 

 human cerebral cor lex are the nervous elements of this organ 

 and that they collectively constitute rather less lluin a cubic 

 inch of protoplasm, it seems abnost incredible that they should 

 serve us as they do. They are the materials whose activities 

 represent all human states, sensations, memories, volitions, 

 emotions, affections, the highest flights of poetry , the most 

 profound thoughts of philosophy , the most far-reaching theories 

 of science, and, when their action goes astray, the ravings of 

 insanity . It is this small amount of protoplasm in each of us 

 that our whole educational system is concerned with Irainiiig 

 and that serves us through a lifetime in the growth of person- 

 ality. "
