Of Consciousness, the Brain, and the Soul

Much as UFO skeptics claim that there is no definitive evidence of alien life, so do most scientists believe that consciousness does not exist outside the human brain. Another way of framing the latter proposition is that there is no proof that the soul exists.

American Enterprise Institute scholar Charles Murray thinks that enough evidence has accumulated to question the brain-only view of human consciousness. [bold added]

the most robust, hardest-to-ignore evidence comes from a phenomenon called terminal lucidity: a sudden, temporary return to self-awareness, memory and lucid communication by a person whose brain is no longer functional usually because of advanced dementia but occasionally because of meningitis, brain tumors, strokes or chronic psychiatric disorders.

Terminal lucidity can last from a few minutes to a few hours. In the most dramatic cases, people who have been unable to communicate or even recognize their spouses or children for years suddenly become alert and exhibit their former personalities, complete with reminiscences and incisive questions. It is almost always followed by complete mental relapse and death within a day or two.

The phenomenon didn’t have a name until 2009, but case studies reach back to detailed clinical descriptions from the 19th century. Hospices, palliative-care centers, and long-term care wards for dementia patients continued to observe the condition during the 20th century but usually treated it as a curious episode that didn’t warrant a write-up. With the advent of social media, reports began to accumulate. We now have a growing technical literature and a large, systematic sample compiled by Austrian psychologist Alexander Batthyány.

Two features of the best-documented cases combine to meet Sagan’s standard: The subjects suffered from medically verified disorders that made their brains incapable of organized mental activity; and multiple observers, including medical personnel, recorded the lucidity.

A strict materialist explanation must posit a so-far-unknown capability of the brain. But the brain has been mapped for years, and a great deal is known about the functions of its regions. Discovering this new feature would be akin to finding a way that blood can circulate when the heart stops pumping.

Charles Murray analogizes the current state of consciousness science to the late 19th century problems with Newton's physics that required the creation of a new theoretical model:

I see the strict materialistic view of consciousness as being in roughly the same fix as Newtonian physics was in 1887, when the Michelson-Morley experiment proved that the speed of light doesn’t behave as Newton’s laws said it should. It took 18 years before Einstein’s theory of special relativity accommodated the anomaly.

We are identifying anomalies in the materialist position that must eventually lead to a paradigm shift. Science will have to acknowledge that even though conventional neuroscience explains much about consciousness under ordinary circumstances, something else can come into play under the extreme conditions of imminent death.

The implications are momentous. Astrophysicist Robert Jastrow observed that for a scientist trying to explain creation, the verification of the big-bang theory “ends like a bad dream”: “As he pulls himself over the final rock, he is greeted by a band of theologians who have been sitting there for centuries.” Neuroscientists who have been trying to explain consciousness may have to face their own bad dream: coming to terms with evidence for the human soul.

The 21st century was predicted to be the century of the Brain or when the war on cancer would be won. But the century of "soul science"? That wasn't on my bingo card.
