192 UNIVERSAL EVOLUTION 



presenting themselves for solution in life. It forms 

 new molecular routes in the brain, and thus gives 

 greater power. It throws out nervous short cuts to 

 other sense centers, in proportion to the pertinence of 

 the education received. But, unless the brain struc- 

 ture exists, or is thus formed, there can be no educa- 

 tion; and the degree of its efficacy depends upon the 

 quality, and power, of the structure, either inherited, 

 or induced by education. In walking, every .one has 

 a stride peculiar to himself, and wears his shoes, at 

 certain places on the soles, different from other walk- 

 ers. What causes these peculiar differences? It is the 

 anatomy of the bones and muscles of the legs peculiar 

 to each. On account of this anatomy, it is impossible 

 for each to walk in any other manner. The physiology 

 of the organism in every part depends, in the same way, 

 upon the structure. The outer expressions, in the body 

 movements, are all determined by the anatomical 

 structure, so are the outer expressions of the nerve 

 physiology determined by the ganglionic neural struc- 

 ture. They are predetermined, by the anatomy, and 

 the personal differences, of individuals. Both the 

 physical, and psychical expression have for their basis 

 the variations in personal anatomy. The differences 

 in the anatomy of the bones and muscles, and the con- 

 sequent variations of their outer expression, are much 

 more apparent to the senses, than are those of the 

 nervous system. But the same law, of interaction of 

 structure, and function, governs both ; although the 

 subtlety, and its location in the body beyond ordinary 

 observation while life lasts, make it appear, to the in- 

 different observer, to be predetermined by a different 

 law. In principle there is no difference between the 

 equilibration of structure and function of both.
