are homologous with the flexors, the spinal cord with the 

 extensors ; the nerves with the air, the medulla with the 

 earth ; the former with the arteries, the latter with the 

 veins ; the nerves are thus what is more active, the 

 medulla that which is more inert. 



2047. On that account the nerves only are in inter- 

 course with the world, while the medulla broods within 

 itself. Consequently, both these nerve-formations are 

 not as yet the pure self-substantial nervous blossom, 

 which no longer imitates flesh and bone, but only itself. 



Brain. 



2048. The highest point attained by the lower sys- 

 tems are the orifices of the viscera, the mouth and the 

 nose. The mouth is the first animal sign, which the 

 plant gives off in the blossom from itself. The Noblest 

 lies therefore at the anterior extremity of the animal, or 

 in man in the direction upwards. 



2049. It consequently occupies the middle point, or 

 one that is between the anterior flesh and the posterior 

 bones, and at the same time the spot, from which all 

 vital processes emerge, or the mouth. 



2050. The oral nervous mass is the Brain. It forms 

 originally the posterior ganglia of the cesophageal ring. 



2051. The situation of the brain is essentially in front 

 of or above the body, in opposition to the sexual parts, 

 which are the lower totality. 



2052. It is, however, above and behind; for it is 

 originally situated posteriorly. The brain can therefore 

 originate only, when the posterior medulla inclines from 

 above forwards, making a curve in the latter direction ; 

 the brain is a spinal cord that has been bent from above 

 forwards. 



2053. The more the spinal cord is curved forwards, 

 so much the nobler is it. This is self-evident. 



2054. The brain is a spinal cord which makes the 

 transit from the signification of bone to that of flesh. 



2055. In the brain therefore the tendency must
