The brain is a complex system, but that doesn't mean it's incomprehensible. Our neural circuits were carved by natural selection to solve problems that our ancestors faced during our species' evolutionary history. Your brain has been molded by evolutionary pressures just as your spleen and eyes have been. And so has your consciousness. Consciousness developed because it was advantageous, but advantageous only in limited amounts.

(...) no spectator is needed, because your consciousness basically is your reality model. I think that consciousness is the way information feels when being processed in certain complex ways. Since the different parts of your brain interact with each other, different parts of your reality model can interact with each other, so the model of you can interact with your model of the outside world, giving rise to the subjective sensation of the former perceiving the latter.
Max Tegmark
Substantial changes, introduced during the last half of the 20th century, have built a structure so expanded beyond the original Darwinian core, and so enlarged by new principles of macroevolutionary explanation, that the full exposition, while remaining within the domain of Darwinian logic, must be construed as basically different from the canonical theory of natural selection, rather than simply extended.
Stephen Jay Gould
The history of a species, or any natural phenomenon that requires unbroken continuity in a world of trouble, works like a batting streak. All are games of a gambler playing with a limited stake against a house with infinite resources. The gambler must eventually go bust. His aim can only be to stick around as long as possible, to have some fun while he's at it, and, if he happens to be a moral agent as well, to worry about staying the course with honor.
Stephen Jay Gould
Once people accepted the false notion that the earth was older than 6,000-years, regardless of how they justified it with the plain teachings of Scripture, the door was open for acceptance of the evolution theory, which became popular in 1859 after Darwin published his book, "On the Origin of Species by Means of Natural Selection, of the Preservation of Favored Races in the Struggle for Life.” It's been downhill ever since!

It would take me very far back to tell the story of how I developed my consciousness of the evocative power of mural imagery. These are memories of my adolescence and early youth when I lived enclosed within four walls during the time of war. The suffering of the adults and all the cruel imaginings of my age, abandoned to its own impulses amid all the surrounding catastrophes, were drawn and etched all around me.
