vidual and make the reactions of the human mechanism 

 as inevitable as are the reactions of a man-made machine. 



The steam roller cannot perform the work of the auto- 

 mobile, but the difference between the steam roller and the 

 automobile is less than the difference between the savage 

 and the scholar. The essential difference between the 

 philanthropist and the African native, like the difference 

 between the teacher and the pupil, is in their action patterns. 



The white matter of the brain is not a passive mechanism 

 like the matrix of the phonograph record or the beeswax 

 that produces the piezo electric effect. In the white matter 

 of the brain there is a constant electric strain, as is indi- 

 cated by the presence of an electric potential. The origin of 

 the electric strain is the generation of positive electric 

 charge in the brain cells by oxidation. The rate of oxidation 

 in the brain cells is governed primarily by the secretion of 

 the thyroid gland. The thyroid gland is governed by the 

 adrenal-sympathetic system. The adrenal-sympathetic sys- 

 tem is governed by the brain, and the brain is "sparked" 

 by sight, hearing, touch, taste, and smell, thus forming an 

 automatic mechanism. In this intricate physical system of 

 the pupil, the parent and the teacher lay down new patterns 

 of action that, by training, increase the capacity of the 

 brain cells of the child to generate radiant and electric 

 energy. 



The Protoplasmic Bridge 



The parent and the teacher do not need to give instruc- 

 tion in such racial acts as sucking, walking, hunting, fight- 

 ing, mating, drinking, and eating, the patterns of which the 

 child brought over the protoplasmic bridge. Those action 

 patterns came to present-day man not by contemporary 

 external integrative action of the nervous system but by a 

 repetition of the integrative actions transmitted over the 

 protoplasmic bridge from parent to offspring. Affection 

 between mother and child, protection of the young, a taste
