How Spiritual Influx into the Natural Shows Itself in Physics

At this meeting there is a presentation of our new ideas for the interface between the mental and the physical. More specifically: How Influx into the Natural Shows Itself in Physics.
These are new ideas based on inspiration from the Writings of Emanuel Swedenborg, who seems of all history to have the best lead-in to these issues.
How Influx into the Natural  Shows Itself in Physics.

Breaking The Shell: Connecting the Spiritual Cascade to the Physical with New Church Science

There will be a Theistic Science Symposium, Oct. 12, 2019 at the Bryn Athyn college, PA.

The Swedenborg Scientific Association (SSA) and the Theistic Science Group (TSG) are pleased to extend an invitation to the Theistic Science Symposium, Oct. 12, 2019 at the Bryn Athyn college. This event is free for everyone. Sure to be a very fascinating day, please see the agenda for details. Registration requested at http://www.theisticscience.com/BreakingTheShell.htm.
For me this will be very important.  It will be an opportunity to explain in more details my idea for Can minds have effects in nature? How? as described in the previous posting.
The first part of the day will be taken my talks from my colleagues to lay the groundwork, so we can understand how spiritual influx into the natural can and must make sense even within science.  We are discussing our ideas every week in a group Skype call, and we will coordinate the details of our talks to make them easier to follow.
So many people think that materialism is inadequate to understand how minds and spirits might exist and live in relation to the world, but have no good ideas how this might take place. Some think that revealing the quantum physics is important for physical measurements and/or biological operations is the important step to going beyond materialism. In a sense that is true, but the effects of quantum physics are either absolutely essential for even ordinary processes (e.g. in sub-atomic and nuclear physics - my day job), or make only extremely small differences compared with classical physics.
So now I want to show how electric processes of attraction and repulsion could themselves be modified and managed by influx coming from outside the physical.  These effects are much larger than quantum effects, and could well be very important for producing the detailed molecular reactions that occur in cells -- or at least the timing of the molecular processes that need to be managed for the successful life of a cell.

So my talk, and the end of the day, will give more details of what I have in mind for how spiritual and mental things can influence the physical. And do so in a way that minimizes the number of laws of physics that have to be changed to allow this to occur. If you come, you will see!

The event will be live streamed and later available on youtube. Details of that to come.

Quantum mechanics and consciousness - Part 5/8: Mind and Physics as Levels Themselves?

5. Mind and Physics as Levels Themselves?

I have argued that there are multiple generative levels within both the physical and mental realms. The next hypothesis is that the physical and psychological are themselves generative levels linked together, so that physical dispositions as a whole are derivative from mental dispositions within living and/or thinking organisms. We entertain [8] the view that the dualism of mind and body is not an ad hoc division, but one that logically follows from the kinds of causation that exists within a universe in which there are both minds and bodies as distinct ontological substances connected as generative levels.

To see whether this works in practice, we have to consider the detailed requirements of any theory of psychology. At the simplest level of generalization, minds must be able to
  • implement intended functions by feeling and thinking, then using motor areas,
  • establish permanent memories, presumably by means of permanent physiological changes,
  • form perceptions using information from the visual and auditory (etc.) cortexes,
  • follow ‘internal’ trains of thought/feeling/imagining without necessarily having any external effects.
One way that these requirements can be accomplished is by means of the ideas presented so far, formulated in the following three principles:
  1. I. Some physical/physiological potentialities (both deterministic and indeterministic according to quantum physics) are derived dispositions from minds as their principal cause. That is, minds predispose the dynamical properties of some physical objects.
  2. II. The dispositional capacities of the mind are consequentially restricted (and hence conditioned) by their actual physical effects, by means of occasional causation.
  3. III. The pattern of I and II is repeated for individual stages of more complex processes.

These principles together give what has been called conditional forward causation, or ‘top-down causation’. Note that we do not have a fourth ‘bottom-up’ principle that neural events directly cause events to occur in the mind. We do not have general matter → mind causation, although something resembling this does arise, namely selection. This is not causation in the sense of principal causation as producing or generating the effect, but is occasional causation as being a necessary prerequisite.

A strong argument for these three principles is that they are already similar to what is known already to happen in physics. According to quantum field theory we saw how virtual events predispose the ordinary quantum wave function. These virtual events operate deterministically and describe the operation of the electric, magnetic, nuclear and gravitational forces. They are not the actual events of quantum mechanics, as those are the definite outcomes of events like observations. Rather, they are a ‘prior level’ of ‘implicit events’ whose operation is needed in order to derive or produce the potentialities for events like observations. The principle (I) states the analogical result that mental events themselves are a ‘prior level’ of ‘implicit events’ whose operation is needed in order to produce the potentialities for physical events.

The argument for the principle (II) is more general. This principle can be seen as the law according to which your future life is restricted and influenced by your past actions (by selection). Physical events are in this way the necessary foundations for permanent mental history and structure.

Principle (III) has an important corollary connected with the observations of the above section on correspondences:
  1. IV. The mind predisposes the brain to carry out those functions which ‘mirror’ or ‘correspond to’ the mind’s own functions.
Mental functions involve intermediate steps, and these intermediate mental steps predispose suitable intermediate physical steps (by I), and are in turn conditioned or confirmed by them (by II). Thus, the sequence of physical steps follows the sequence of mental steps, and the overall function of the physical process is analogous (in some sense) to the overall function of the mental process.

Quantum mechanics and consciousness - Part 2/8: Substances and Multiple Levels in Quantum Mechanics

2. Substances and Multiple Levels in Quantum Mechanics


A substance is defined as what exists over the finite duration between measurement events. The problem in quantum mechanics of understanding how substances exist has been long-standing. Some like Everett have suggested it is the wave function which exists continuously, but wave functions are mathematical entities and not physical. Others like Bohr have said that only events are real and hence denied that there anything which could be a continuous substance. 

My proposal is use the idea of propensities [5]. These are the underlying dispositions or causes which give rise to events when the conditions are appropriate. The event production may be deterministic or probabilistic. The important feature of propensities is that they are present continuously between events, at least according to the Born Law of quantum mechanics.  Propensities, therefore, can be identified as the substance of which quantum particles are made. The wave function is then the form of those substances, in particular their form as spread out in space and time. Quantum objects are thus substances that manifest themselves in some kind of form. The form of something tells us what its present structure is, and the substance of something tells us how it would behave in all future hypothetical circumstances (even if only by probabilities).

We can develop a theory of multiple levels, each with different kinds of objects and each existing in their own kinds of spaces.  We can show how objects interact between levels [6]. We can begin to understand this using the principles of quantum mechanics. Consider, for example, how the Schroedinger equation makes predictions for the wave function, which in turn predicts the probabilities of future events. The Schroedinger equation uses a combination of kinetic energy and potentiality that acts to evolve the wave function through time, based on the initial conditions. The wave function then acts to produce further discrete selection events based on previous selections.  In each case, objects of kind of A are producing further objects of kind B(n) based on previous objects B(n-1). The produced B(n) outcomes select what kind of outcomes are next possible.  Furthermore, this same pattern is repeated on multiple levels {A ➝ B  C}.  Quantum physics has the levels  {energy   propensity forms  actual selections}.  Such patterns are familiar, since in classical physics we have a similar structure with the levels {potential energy  forces  acceleration}.  The pattern is also familiar to us from psychology in the sequence {desire  thinking  action}, as will be discussed later. 

When we start digging into quantum physics, we discover even more levels. The potential energy and kinetic energy that we started with in the Schroedinger equation are not themselves fundamental, but are generated by the virtual processes of quantum field theory. Potential energy is produced by the exchange of gauge bosons: of photons of electromagnetic energy, of gluons for nuclear energy, etc. And kinetic energy comes from mass, which is mostly not ‘bare mass’ but is the collection of the energies of virtual substances in a cloud around a given center.   This means that we have an even longer chain of multiple generative levels in quantum physics, something like {variational Lagrangian  virtual fields  virtual events  potential and kinetic energies in the Hamiltonian  propensity fields described by wave functions  selection events for actual outcomes}. 

These kinds of levels are generally acknowledged to exist within quantum field theory, but with differing opinions about their significance. Many physicists and philosophers of physics want to assert the particular ‘reality’ of one of the levels and say that the prior levels are ‘merely calculational devices’ for the behaviour of their chosen real level. The question of simplicity, to be answered in order to apply Occam’s razor, is whether it is simpler to have multiple kinds of objects existing (even within multiple generative levels) each with simple dispositions, or simpler to have fewer kinds of existing objects, but with more complicated laws governing their operation. 

      Allowing the multiple generative levels all to exist in ‘their own way’ has fruitful consequences for generalizing quantum physics to include new kinds of causation. Admittedly this is going beyond standard quantum mechanics, but at least this is yielding predictions for possible new science which can be confirmed or falsified as all science should be examined.

Quantum mechanics and consciousness - Part 1/8 of thoughts on a causal correspondence theory

Which way does causation proceed? The pattern in the material world seems to be upward: particles to molecules to organisms to brains to mental processes. In contrast, the principles of quantum mechanics allow us to see a pattern of downward causation. These new ideas describe sets of multiple levels in which each level influences the levels below it through generation and selection. Top-down causation makes exciting sense of the world: we can find analogies in psychology, in the formation of our minds, in locating the source of consciousness, and even in the possible logic of belief in God.


1. A quantum viewpoint


Over the last 100 years the study of quantum phenomena has shown that there is more than the material world of matter, force and motion. The experts have often speculated about a role for observers, even for consciousness, in an understanding of quantum measurements [1] [2]. More recently many [3] have speculated that quantum physics itself reveals consciousness. There are now many cottage industries seeking to develop ideas of ‘quantum consciousness’, even of ‘quantum spirituality’. It has become popular to say that ‘quantum theory shows that consciousness creates physical reality’, and that this fits into an advaita non-dualist framework where only the Godhead is real while everything else is a generation of consciousness.

For many, however, such a monism where all beings are numerically identical does not seem to be the ultimate answer. People generally consider unselfish love to be superior to selfish love. If all persons were identical in being, then unselfish love between distinct persons would be impossible. The reality of unselfishness disposes many of us to dualist views in which people are ontologically distinct and in which God and worlds are distinct [4, p. 18]. It is important for theorists to explore theories in which minds and god are distinct. If mind and matter are distinct then many philosophical problems with materialism may be resolved.

I here present some ideas to help interpret quantum mechanics, mind and theism in a non-reductive approach. These ideas describe a set of multiple levels which all exist simultaneously in their own manner. Rather than everything being a system of objects at one fundamental level, we can develop a theory of multiple levels, each with different kinds of objects existing in their own kinds of spaces. The first challenge is to see how quantum substances exist on a single level. A second challenge is to show how objects interact between levels.

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.

Physical and Mental Substances: what are the stuffs of nature?

Here is a potted summary of a non-reductive 'propensity account' of physical and mental substances:

Quantum theory must deal with substance, but just not substance of the classical material or atomistic kind.  Rather, something that perseveres through time without existing in a actualized form at every moment. The substance would be something like the 'potentiality' or 'propensity' for acting, and that acting occurs with non-zero time steps, not continuously. This is the 'propensity interpretation' of quantum mechanics, initiated by Heisenberg and Popper. Because of the finite time steps, propensities exist and persist from one event to another actualization. Between events, therefore, they are the substances of quantum things.

We talk about mental information, and ask "what property of substance, makes it amenable to human cognition". You (like many others) are asking, 'what is the stuff of mind?'. My answer is an extrapolation of what I said above for quantum physics. It is 'potentiality' or 'propensity' but now of mental kinds. What is that, you ask? Do I know it? Yes: I say. It is the 'love' or 'desire' that make a person. For loves and desires are what in us persons that does persist. Again we make actualizing decisions intermittently. Between those decisions it is our love which persist. Love is our mental/personal substance. Just (certainly not!) material substance!

Quantum objects are propensity-substances in various forms. Those forms are the wave functions of quantum theory.
Mental objects are love-substances in various forms. Those forms are the information of mental kind, a.k.a thoughts and perceptions. The actions of love (a.k.a. decisions) have physical effects.

These ideas are based on the ideas of the kind Aristotle might have had without much effort, though in fact he did not. Just remember that there are two kinds of substances (at least), and the kinds are not reduced to another, or aggregates of other kinds. It is the job of physicists and psychologists to determine how the two kinds of substances actually cause things, and hence what they actually do.

There are functional correspondences between the way physical and mental things exist and operate, even though the substances involved are completely different and can never be transformed one into another.
