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 pharyngeal 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 principally reside, to give off nerves, and perfect them into self-substantial nervous organs.
2056. In man the brain with its nerves curves round like a crosier, and that more perfectly than in any other animal. The spinal cord therefore in the highest formation of the brain returns again parallel to the direction, in which it has ascended.
2057. In the brain there is of necessity the greatest quantity of nervous mass. The brain is the nervous trunk, as the liver is probably the vascular trunk.
2058. In the brain the cystic formation has been most purely represented; as e. g. in the cerebral cavities or ventricles. The brain is the stomach of the nervous system or its lungs.
