The point thus far of the story, is that while built into human life was a forced relocation of man in his nervous system, from a non-conscious, strictly instinctive, simpler, more peaceful, jungle homeland, (now fondly remembered as Eden), to an internal city of noise, excitement, constant uncertainty and stress. (Babel perhaps?)
Also built into him is, (when the matter comes to his attention), a propensity to long for the previous way of life, and to condemn the present one. Truly not unlike the feeling you would expect from people driven from their peaceable, agreeable homeland to a foreign place of foreign habits. But none of this has any practical significance in that life does not go backwards. Men are not ever going to go back home, well not to THAT home. No matter that to many it feels like their natural home, which is simply due to the fact that it was their first home, along with thought’s tendency to nostalgia.
As witnessed by the commonality of social criticism of all varieties, men do believe that the train can be backed up; that the circumstances in which a people now live can be abandoned in favor of previous ones. Almost every human on this planet, if asked, will say that this is certainly within the realm of possibility, but they are incorrect, and the proof is everywhere they look, (if they were actually seeing when they look).
Man is not going back, and cannot go back to a non-conscious, instinctive brain stem life. The one he now leads is in no way un-natural. He once lived in an animal child; he now lives in an adult city; he was forced to go and he went, and that ends this part of the story.
The few people who feel an innate need for a more personally satisfying picture of what life is about than is ever available from any city analysis or jungle legend, likewise experience this longing, (which the ordinary identify as being for things past). Also the troubling sense that the life they are leading is somehow, not-quite-right, (labeled by routine men, un-natural), but they differ from everyday people, in that their awareness of these twin sensations is not periodic and momentary but persistent.
