While there are more neural connections within a half brain than between the two halves, there are still massive connections across the hemispheres. Even so, cutting those connections does little to one’s sense of conscious experience. That is to say, the left hemisphere keeps on talking and thinking as if nothing had happened even though it no longer has access to half of the human cortex. More important, disconnecting the two half brains instantly creates a second, also independent conscious system. The right brain now purrs along carefree from the left, with its own capacities, desires, goals, insights, and feelings. One network, split into two, becomes two conscious systems. How could one possibly think that consciousness arises from a particular specific network? We need a new idea to cope with this fact.

Symbols lead a double life, with two different complementary modes of description depending on the job they are doing. In one life, symbols are made of physical material (DNA is made of hydrogen, oxygen, carbon, nitrogen, and phosphate molecules) that follows Newton’s laws and constrains the building process by its physical structure.

Newton’s laws aren’t fundamental, they are emergent; that is, they are what happens when quantum matter aggregates into macroscopic fluids and objects. It is a collective organizational phenomenon.
