I have two posts lined up on this topic, starting off this week with a discussion of The Transcendent Brain: Spirituality in the Age of Science (Pantheon Books, 2023) by Alan Lightman, a PhD physicist who also teaches and publishes in the humanities. In this fairly short book (and the older I get, the more I like short books) he makes a case for what he calls “spiritual materialism.” Starting with brain science, he builds up to an informed discussion of consciousness and transcendent (or spiritual) experience. It’s a good read.

Body, Brain, and Mind

Christians (and others) call it a soul. Mormons call it a spirit. The widespread belief that we humans are not just mysteriously animated bodies but are essentially spirit beings somehow joined to a physical body goes way back before Mormonism and even Christianity. The Mormon belief in a spiritual Pre-existence is unusual, but the belief that after the death of the body a soul or spirit lives on in Heaven, Hell, or some spiritual waiting room is, again, widespread. It is not the case that this spirit narrative is necessarily part of religious belief and practice, but it is certainly a central feature of Christianity and Mormonism.

Just think, for example, of LDS temple work. Proxy baptisms and endowments are performed so that spirits of dead people can move from the spiritual waiting room to, uh, some upgraded spiritual waiting room until resurrection and judgment, after which they can enter the full blown Celestial Kingdom. Proxy ordinances make no sense without living spirits of dead people for whom the ordinances are done. And temple sealings make no sense without the postmortal continuation of spirit life (eventually reunited with a resurrected body, which for anyone dead for more than a generation or two is a completely new body).

In the first chapter the author Lightman reviews what in philosophy is called the mind-body problem. Is the existence of a spirit or soul necessary to explain human consciousness? Most cognitive scientists and philosophers say no, then try to explain how the full human mental experience emerges from a material brain. Lots of good work being done. Descartes, who initiated the modern philosophical discussion, gave a secular account affirming both a mind and a body, leaving later thinkers to grapple with the tricky problem of how they are joined and how they interact. Modern scientists look at a different problem: how human mental life emerges from a material brain. Two entirely different problems. Spiritual theists (including Mormons) see no problem at all: there’s a conscious, thinking spirit inside a physical body, and when the body dies, the spirit continues.

Consciousness and Transcendence

The second chapter looks at materialism through the ages. The third chapter looks more closely at human consciousness. You don’t have to be conscious to be alive. Many living things are not conscious. That tree outside your house isn’t conscious. You aren’t conscious when you are asleep. An even deeper level of alive-but-not-conscious happens in a coma or when under medical anesthesia. But it’s our degree of consciousness, self-consciousness, and rationality that really sets us as humans apart. The big question here is whether the material brain can produce not just consciousness but also transcendent or spiritual experiences — that is, whether such a supernal experience can have an internal source or explanation (and be subject to scientific investigation and explanation) or whether such experiences must have an external source or explanation, God or an angel or Nature or “the Force.”

For spiritual theists, there again is no mystery, no problem to explore. In-group transcendent or spiritual experiences are from one’s own God or Cosmic Force, although out-group spiritual experiences are generally ignored or, when acknowledged, dismissed as somehow not authentic. And transcendent or spiritual experiences are cited by believers as foundational for their big religious narrative (Moses at the burning bush, Jesus and three apostles at the Mount of Transfiguration, Joseph in the Sacred Grove) and also, on a smaller stage, as an anchor for personal religious commitment.

Here’s how one researcher quoted in the book (p. 120) sums up the materialist brain theory of transcendent or spiritual experiences, the internal source model:

You can get them in near death experiences, you can get them with a drug called 5-MeO-DMT, you can get them when you meditate. We know that our brain can produce love and hate. This [transcendent experience] is another feeling that the brain can have. And experience shows that our brain can produce all these feelings of love and hate, of ecstasy, of feeling connected.

Transcendence and Revelation

In the fourth chapter, author Lightman looks more closely at spirituality. There is a discussion of awe. Small word, big feeling. You have probably felt it when looking at a broad vista from a mountaintop, or when standing close to a thundering waterfall. Perhaps you have had a religious or spiritual experience that induces awe apart from an overwhelming environmental prompt. Lightman cites a Jonathan Haidt paper for the distinctive features of awe: (1) “a perceived vastness,” which Lightman explains as “a perception of being in the presence of something larger, grander, and more powerful than ourselves,” and (2) “a need for accommodation, defined as an inability to assimilate an experience into current mental structures.” (p. 154)

Lightman also discusses creative thinking, and this is where things get interesting. It’s not merely spirit-thinking or awe-inspiring experiences that give us a sense of something outside of ourselves. Creative thinking does it, too. Ancient poets would thank the Muses for inspiring them. Artists, novelists, scientists, and mathematicians have creative episodes where the solution to a problem or challenge suddenly comes to them, possibly when they are not thinking about it or even when they are asleep, often after weeks or months of pondering and reflecting. Lightman cites 19th-century psychologist Graham Wallas for a model of creative thinking in four stages: (1) preparation (mastering the tools of a craft and defining the problem), (2) incubation (mull over the problem in various ways), (3) illumination (a new insight is finally achieved), and (4) verification (apply the insight and work out the consequences). Lightman adds, “the creative transcendent would occur during the incubation and illumination stages” (p. 158-59).

When I read that passage, my reaction was, “Wow, that sounds an awful lot like the Mormon model of revelation.” Or possibly the model of translation that Joseph outlined in D&C 9:8-9. Transcendent or spiritual experiences, monumental creative insights, moving religious inspriration. They all seem to have a lot in common. We as humans are fully capable, it seems, of having these experiences. Some more than others, perhaps. The big question (at least for inquiring minds) is whether the source or sources of these experiences are internal or external. An associated question is whether such experiences are transitory, a brilliant solution to a tough problem but then you move on, or foundational, life-changing in the literal sense. More on that in my next post.

So here are a few things to discuss.

  • Go ahead and share, if you want, your own transcendent or spiritual experience, or that of a family member.
  • How would you distinguish between a normal if striking experience (a lucid dream or a strange coincidence) and a truly transcendent experience?
  • Are drug-induced or drug-enhanced mental experiences valid or contrived? There is a whole field dedicated to the study of the use of drugs within religious traditions. Go look up “entheogens” for some interesting reading. There’s a Mormon chapter as well, but that’s for another post.
  • The big question: do you think transcendent or spiritual experiences are entirely internally produced? Or mostly internal but a few externally produced? Or are external agents or causes responsible for many or all of these transcendent or spiritual experiences?
  • Are all, most, few, or none of the good feelings some people experience when praying due to God or The Spirit? How about the good feelings people in other denominations or other religious traditions experience when praying?
