Using Swedenborg to Understand the Quantum World I: Events

For the last hundred years, physicists have been using the quantum theory about the universe, but they still do not properly understand of what the quantum world is made.

The previous physics (referred to as “classical” and started by Isaac Newton) used ideas of “waves” and “particles” to picture what makes up the physical world. But now we find that every object in the quantum world sometimes behaves as a particle and sometimes behaves as a wave! Which is it? In quantum physics, objects behave most of the time like waves spreading out as they travel along, but sometimes measurements show objects to be particles with a definite location: not spread out at all. Why is that? It is as though their size and location suddenly change in measurement events. This is quite unlike classical physics, where particles exist continuously with the same fixed shape. In quantum physics, by contrast, objects have fixed locations only intermittently, such as when they are observed.  So they only offer us a discrete series of events that can be measured, not a continuous trajectory. Quantum objects, then, are alternately continuous and discontinuous.

Why would we ever expect such a fickle world? Emanuel Swedenborg (1688–1772) has some ideas that might help us. He describes how all physical processes are produced by something mental, or spiritual, and this can be confirmed by reason of the similarity in patterns between the physical processes and their mental causes. In Swedenborg’s words, there are correspondences between the physical and the mental—that they have similar structures and functions, even though mind and matter are quite distinct.

I need to state what correspondence is. The whole natural world is responsive to the spiritual world—the natural world not just in general, but in detail. So whatever arises in the natural world out of the spiritual one is called “something that corresponds.” It needs to be realized that the natural world arises from and is sustained in being by the spiritual world . . . (Heaven and Hell §89)

Although these ideas are not part of present-day science, I still hope to show below that they may have some implications for how science could usefully develop.

Swedenborg’s theory of mind is easy to begin to understand. He talks about how all mental processes have three common elements: desire, thought, and action. The desire is what persists and motivates what will happen. The thought is the exploration of possibilities for actions and the making of an intention. The action is the determined intention, the product of desire and thought that results in an actual physical event.

The [actions] themselves are in the mind’s enjoyments and their thoughts when the delights are of the will and the thoughts are of the understanding therefrom, thus when there is complete agreement in the mind. The [actions] then belong to the spirit, and even if they do not enter into bodily act still they are as if in the act when there is agreement. (Divine Providence §108)

All of the three spiritual elements are essential. Without desire (love), or ends, nothing would be motivated to occur. Without thought, that love would be blind and mostly fail to cause what it wants. Without determined intention, both the love and thought would be frustrated and fruitless, with no effect achieved at all. In everyday life, this intention is commonly called will, but it is always produced by some desire driving everything that happens. 

Here is the pattern:

      Spiritual                                                                   Natural
Desire + Thought => Mental Action (Intention)    >>    Physical Action, or Event, in the World

Swedenborg summarizes the relationship between these elements as follows:

All activities in the universe proceed from ends through causes into effects. These three elements are in themselves indivisible, although they appear as distinct in idea and thought. Still, even then, unless the effect that is intended is seen at the same time, the end is not anything; nor is either of these anything without a cause to sustain, foster and conjoin them. Such a sequence is engraved on every person, in general and in every particular, just as will, intellect, and action is. Every end there has to do with the will, every cause with the intellect, and every effect with action. (Conjugial Love §400:1–2)

Now consider Swedenborg’s theory of correspondences mentioned above. He says that there is a similar pattern between the details of the effects and the details of the causes. ”As above, so below,” others have said. So if mental action produces some effect in the physical world, then, by correspondence, we would expect a similar pattern between that physical effect and each of the three elements common to all mental processes. We would expect something physical like desire, then something physical like thought, and finally something physical like mental action. Do we recognize these patterns in physics? And if so, do we recognize them better in classical physics or in quantum physics?

I claim we do recognize them in physics:

• We recognize the “something physical like desire” as energy or propensity. These are what persist physically and produce the result, just like desire does in the mind. They are in both classical and quantum physics.
• We recognize the “something physical like thought” as the wave function in quantum physics. This describes all the possibilities, propensities, and probabilities for physical events, just like thought does in the mind.
• We recognize the “something physical like mental action” as the actual specific physical outcome, a selection of just one of the possibilities to be made actual. This is a measurement event in quantum physics, the product of energy or propensity and the wave function, just like the product of desire and thought is the mental action.

We will discuss energy and wave functions in later posts, focusing here on the final step of mental actions and physical events. According to Swedenborg’s ideas, the structure of mental processes and the structure of physical events should be similar. So, too, the function of mental processes and the function of physical events should be similar. Can we tell from this whether we should expect a classical world or a quantum world?

One feature of thought and mental action with which we should be familiar is time. That is, we always need time to think! Without any time gap between desiring and intending, we would be acting instinctively and impulsively. Sometimes that works but not always (at least in my experience!). Most often, there has to be some delay, even some procrastination, between having a desire and fulfilling it. That delay gives us time to deliberate and decide on the best action to select. And, most importantly, if it is we who decide when to act, we feel that we act in some freedom. It feels better.

If the physical world corresponds to those mental processes, according to Swedenborg, what hypothesis do we reach about physics? It is that there will be corresponding time gaps between the beginning of some persisting energy or propensity and the selection of physical outcome. Remember that quantum objects are selected and definite only intermittently—when measured, or observed—while classical objects are continuously definite with no gaps. All this leads us to expect that physical events should not be continuous; that is, we should expect a quantum world rather than a classical world.
