As science has steadily undermined the long-held beliefs of religion, almost all that remains for people of faith is to say that God is and will forever be a mystery. Insofar as Einstein was religious, he possessed a feeling of awe and wonder at the mystery of the universe. But science hasn’t stopped chipping away at mystery, promising to reduce spiritual experience to measurable brain activity. It’s doubtful that belief in God, the soul, heaven and hell, and other tenets of faith will be drastically affected – polls continue to show that these things remain articles of belief for around 80-90% of responders.
Will neuroscience eventually be able to locate God in our neurons, and if so, should that tiny area of the brain be excised or boosted? No doubt there are arguments on both sides, depending on whether you hold that God has been good for the human race in the long run or bad. Setting aside such judgments, it turns out that the possibility of finding God in the brain creates a baffling mystery that neither religion nor science can tackle alone.
Now that advanced brain scanning can map the way our brains light up with each thought, word, or action, it’s clear that no experience escapes the brain. For a mystic to see God or feel his presence, for St. Paul to be suddenly converted on the road to Damascus, or for St. Teresa of Avila to have her heart pierced by an angelic arrow, such experiences would have to register in their brains. However, this indisputable fact (so far as present knowledge extends) doesn’t give science the advantage over religion. For it turns out that the brain has definite limitations on what it can experience.
The work of the late Polish-American mathematician Alfred Korzybski (1879-1950) is relevant here, because Korzybski worked out the layered processing that goes into the way we perceive everyday reality. Billions of bits of data bombard our sense organs, of which only a fraction enter the nervous system. Of that fraction, more of the raw input is filtered out by the brain, which uses built-in models of reality to discard what doesn’t fit. When people say “You’re not hearing me” or “You only see what you want to see,” they are expressing a truth that Korzybski tried to quantify mathematically.
Sometimes the things a person doesn’t see are simply outside the range of human experience, like our inability to see ultraviolet light. But a great deal more depends on expectations, memories, biases, fears, and simple close-mindedness. If you go to a party, and someone tells you that you are about to meet a Nobel Prize winner, you will see a different person than if you are told he is a reformed Mafia hit man. When all the filtering and processing is complete, there is no doubt that the brain doesn’t actually experience reality but only a confirmation of its model of reality.
Two interesting points follow:
- All models are equal as viewed from the level of the brain.
- Reality transcends any model we can possibly make of it.
These two points allow God, the soul, and all other spiritual experiences back into the picture. The first point demolishes the notion that science is superior to religion because it gathers facts while religion deals in beliefs. In truth, science filters out and discards a huge portion of human experience – almost everything one would classify as subjective – so its model is just as selective, if not more so, than religion’s. As far as the brain is concerned, neural filtering is taking place in all models, whether they are scientific, spiritual, artistic, or psychotic. The brain is a processor of inputs, not a mirror to realty.
