The Geometry of Thought

It is not directly possible to know the exact circumstances, or selection pressures, that favored the development of the human brain. Consideration of its structural evolution, and comparative research, on human and nonhumans (other members of the primate order) have provided insights into the early ‘drafts’ of the modern mind. It is believed that, during the evolution of our mind, the nervous system changed in a number of manners, four to be precise. The arrangement of organs first became centralized in architecture, being the next step of evolution from a loose connection of nerve cells, as in jellyfish, to a spinal column and complex brain with impressive swellings at the hindbrain and forebrain. Centralized architecture led to hierarchy amongst structure and it appears that newer ‘drafts’ of the brain overtook the earlier additions and in effect became the Operator, the master of the domain of evaluating sensations…
