The Merits and Demerits of Quantum Explanations

Almost since the rise of quantum mechanics, the physics of the very small, speculative thinkers have formed a kind of aura around the field in attempts to help them give various puzzling phenomena  a scientific explanation. Among these are consciousness, the mind-body problem, telepathy, near-death experiences, and the like.

A philosophically serious attempt in this direction is an appendix in Hans Jonas’ book, The Imperative of Responsibility, 1979. The appendix (pp. 204-231 in the 1984 University of Chicago Press edition), is titled “Impotence or Power of Subjectivity, A Reappraisal of the Psychophysical Problem.” I have read many other such takes, to be sure, but none has shown any rigor, whereas Jonas’ work does. He tackles the problem that Descartes had already struggled with. Assume that we do have an autonomous spiritual self, however it is called (res cogitans by Descartes, subjectivity by Jonas); hereafter I’ll refer to it as “self.” How does this immaterial something interact with the physical world in a meaningfully causal way—or vice versa?

The merits of quantum mechanics as an explanation lie in the fact that it deals with the extremely tiny phenomena at the subatomic level—where the energies involved are also minute. The tentative solution to the mind-body problem is that the self, whatever it is, may have energy enough to move “matter” at the quantum level. Then, if an appropriate structure of amplification has evolved, thus a neuronal network like the brain, an immeasurably tiny intervention by the self can eventually result in a physical action like raising the arm or saying something, both because I want to. This has merit—and produces, at least in me, a kind of intuitive ascent. It points to a potential explanation—and Jonas does not go any further than that. The only assumption we have to make is that the self at minimum has some minute ability to interact with matter at the subatomic level.

The demerits of quantum explanations (and Jonas does not go there, but others do) is to suggest that the only difference between what we traditionally call the spiritual and contrast to the material is a difference in density or wavelength. Therefore souls are just as material as everything else—they’re just made of more subtle stuff.

Here I have the opposite reaction. I don’t believe a word of it. There may be subtle regions made of subtle matter, etc., etc., but matter, no matter how subtle, can’t possibly produce consciousness. The entity we call the self, therefore, is different from matter in kind, not just in degree. Nor is it absent in this coarse material realm. It’s plentifully present here in the ordinary world—and doing plenty of damage as well as good. And in both realms (coarse and subtle) it has, no doubt, a certain amount of force that it can exercise. In these dense regions, however, to exercise that force on the congealed energies we call matter, it needs amplification through machines—of which our bodies are the first and most potent versions.

Jonas wrote his appendix before extensive assembly of data on near-death experiences had even begun. One of the interesting result of those studies is the discovery that disembodied selves have the devil of a time interacting with other people—but an easy time passing through walls. But they do move about, more or less at will. Separated from their tool, the body, they are seriously handicapped here. But, presumably, not so in the regions beyond the border. Manner of speaking. And it would seem to me, those who first arrived here, finding themselves in this valley of dense matter, started to mess about with particles at the quantum level. And lo and behold. In the wink of a few millennia they had made the first living cell. First came chemical civilization, fashioned by nudging quantum particles this way and that. Next came life, then civilization. And now back to studying quantum mechanics again. What goes around comes around. But what they were then, and we still are, is something other than either energy or matter. This is a vale of body-making, not of soul-making.

What Can’t Be Mechanized

The religious life is a good candidate. But when I think about that, I realize that the religious life is just one aspect of individual soul development. Learning can’t be mechanized either. My meaning for mechanized? I mean repetitive behavior, following rules, repeating formulae, willing the truth of doctrines as opposed, say, to penetrating to their core meanings. The worst kind of mechanization, of course, is tribal behavior—where the faith is just a label of belonging to an “us.”

Excessive use of abstraction is a particularly dangerous habit in those spheres where the genuinely human is the core—provided that my own conviction is correct, namely that we belong to a much more sophisticated, subtle, and free order as souls than we do as embodied souls. It is a mistake to think that people who belong to one of the great religions, especially those with lots of ritual, are uniformly following rites and nothing else is going on. As there are no two snowflakes that are identical so also no two Catholics, Baptists, Buddhists, or Muslims are identical either, or any two adhering to yet some other faith—or none; vast differences separate individuals.

To the contrary however, all athletes train the same way and underpinning all good bridges is genuine engineering functionally identical, whether in their design computers, slide-rules, or just plain reasoning and experience guide the construction. The physical and soul realms have radically different characteristics. The soul escapes all mechanical constraints; you can put the harness on, but it won’t hold the horse. That is both a blessing and a problem. If only we could find the magic phrase or the right sequence of motions…

There is a big difference between the channel that brings the water and the water that it brings. All religious battles are about stonework, embankments, depth, shape, decoration, and such—the engineering of the channel. Interesting subject, to be sure—but the water is the same in all and what it’s all about. But while the human body needs the ordinary water and knows precisely how to use it, individual reception of the higher water, Grace, is much more subtle and complicated. We thirst for it but don’t know what we thirst for. In that realm, where mechanics have no rooting at all, the process of development is invariably and damnably subtle. We have to develop enough as individuals—whether in a system or outside it—before it begins its work in us. It requires learning; but how that process actually takes place is a great mystery, despite vast Babels of learning applied to education all over the world—as, seemingly, we get ever more stupid.

Kneeling Before Physics

I’ve argued elsewhere more than once (i.e., on Ghulf Genes) that we are “heading back,” thus that we are—culturally—on our way back from the summit of Mount Matter to climb again Mount Spirit. On the way there, thus at present, we’re in the Valley of the Shadow of Death. I find it fascinating that these days those who newly discover that the transcendental order must be real after all—and wish to persuade others of this fact—almost reflexively reach for their proofs in physics. The chosen methodology has little to do with the facts of the matter but everything to do with human nature. To persuade others you need Authority; and these days physics has authority. Einstein is the word that equals wise today—and the atomic bomb made the biggest thunder ever over Japan just a few decades back. If physics is the orthodox religion of modernity, quantum physics is its mysticism, hence the best pool of proof of all.

I was reminded of this forcefully reading a book by Pim Van Lommel on the near-death experience. Lommel is a cardiologist and, these days, a leading figure in NDE studies. The book is Consciousness Beyond Life. It’s a mixed sort of product, stunningly excellent in parts. But it fails as a “work.” It is a kind of together-binding of magazine or journal articles padded out into chapters. The book’s early chapters cover the same ground Raymond Moody did in Life After Life; in many areas Lommel’s book is more complete and thorough, in others interestingly selective. Moody gave very strong emphasis to the spirit’s reception in the beyond by a “being of light.” In Lommel’s presentation the testimonials he chose to illustrate this aspect support a much more pantheistic feeling. But it is Lommel’s main thematic I found interesting as an indicator of our times; but Lommel’s case, I hasten to add, is just one of many. He reaches out to physics for his theme and latches on to the concept of non-locality, a discovery of quantum mechanics.

In the crudest form, locality means that if someone punches me hard on the chin, the lady waiting for the bus a block away won’t fall down. She cannot be affected by what happens to me. In more sophisticated form, this means that for B to be affected by A in some way, communication must be possible between A and B; and this communication cannot take place more rapidly than the speed of light. Non-locality means that in some way, anyway, the pain I feel when punched does affect the lady waiting for the bus; my negative experience is communicated to everyone; others don’t have to feel it consciously, but it is so. It also means that instantaneous communications between A and B are possible, even if these two are moving away from each other at the speed of light.

Now it so happens that non-locality has been proved to exist in quantum physics. Two elementary particles can be caused to come into being by producing particle decay. These particles will be “entangled” with each another; thus if A has an upward then B will have a downward spin. If you change the spin of A, the spin of B will necessarily change as well; that’s what entanglement means. And this can happen even when they’re far apart. Experiments have been conducted so that A and B are caused to fly apart at the speed of light. Then the spin of one is forced to change—while the spin of the other is detected. Sure enough, as A changes, so does B. B seems to know that A has changed and thus conforms to be in harmony—but the “signal” between the two, if there is a signal, must have travelled faster than the speed of light. As physicist understand the matter—and they are clearly concerned not to violate Einstein’s iron law on the speed of light—no signal actually passes. Far separated although in space they are, A and B remain linked in a mysterious field relationship.

Now, you might ask, what does any of this have to do the ability of a human consciousness to survive the death of its body? The commonality here is relatively limited. Communications at a distance without a signal are difficult for modern man to grasp. Indeed, Einstein hated the notion of non-locality and tried to defeat it to the best of his ability. Similarly, for the modern mind—but not for those of us who grew up still embedded in hoary old traditions—the notion of human survival of death is a similar scandal. That’s the real linkage. What is interesting here is that appeal to physics, rather than to human reason and intuition, strikes Lommel as appeal to a Higher Authority. Lommel might have used Rupert Sheldrake’s Dogs That Know When Their Owners are Coming Home as his proof; Sheldrake’s findings also show “action at a distance” without discernible signaling, especially when the owner is downtown and the dog in the suburbs thirty miles away. Alas the truth is that the highest authority available to us is our own mind.
