Q: As a physicist, can you describe the mechanism that allows interaction between the physical and the "spiritual?"
Me: As a physicist, no, I cannot. As a physicist I must stick with what is confirmed as objectively observed (observer independent). I use the term spiritual for that which is non-physical which by my definition is that which is filtered out by this method that science uses to ensure that its observations are objective.
Therefore I can only describe this mechanism by first assuming that such non-physical things are real, but then as a philosopher with some familiarity with physics I can explain this partly physical process by which such an interaction occurs.
In my metaphysics (i.e my theory of the nature of reality), the non-physical or spiritual are also forms of energy but these differ from the physical in two ways. The first is that physical forms of energy are actually all parts of a single form of energy which is the whole multidimensional space-time structure that is the physical universe, but spiritual forms of energy are not a part of this structure at all. The second is that physical forms of energy have these quantitative characteristics that spiritual forms of energy do not have.
Q: The spiritual is a form of energy, but not any form of energy that has been observed; ie. not part of the space-time structure or specific in characteristic. Correct?
Me: I would not say that it is not observed but only that not being a part of the multidimensional space-time (mathematical) structure they are not observed in a manner gets through that filter of science that accepts only what is observer independent and not in a manner that is ammenable to a consistent mathematical description. Nor would I say that they are not specific in characteristics but only that they are not of a quantitative nature - these are not the same thing, though I do understand that to you these may seem closely related, especially if you presume as most metaphysical naturalists do, that the particulate nature of the physical world is the only reality there is.
Moving on. One of the most basic parts of this multidimensional space-time mathematical structure, which is the basis of physical law, is that the energy of physical forms is bound by a rule of quantity which we call the conservation of energy (and momentum). But this law is only absolute on a macroscopic scale of space-time because of the uncertainty principle in quantum physics. The uncertainty principles of dE x dt ~ h (Planck's constant) and dp x dx ~ h are actually closely related since E (energy) and p (momentum) as well as t (time) and x (distance) are actually components of the 4 vectors (E,p) and (t,x). Anyway the point is that this most fundamental law of physics binding energy and momentum to definite unchanging quantites has a space-time window in which exceptions can ocurr. This means that energy which is not a part of this conserved quantity (spiritual forms of energy) can interact with that which is (physical forms of energy) as long as it occurs in small enough intervals of space and time. This does not allow such non-conserved non-physical forms of energy to add to the energy or momentum of the physical world on a larger scale but it DOES allow them to change the course of events (in a very subtle manner).
Q: Yes, but tread carefully over conservation of energy and momentum as you continue, making sure to address them as you go. I'm interested in hearing the 'exceptions' as well, as I'm not aware of any energies that wouldn't be part of the conserved quantity.
Me: I don't know what you mean by your first statement. The discovery of quantum physics is that the laws of conservation of energy and momentum are only observed on the larger (non-quantum) scale of space time. This is what those uncertainty principles (dE dt ~ h and dp dx ~ h) mean. dE represent the energy that can appear out of nowhere and dt represent the time during which this energy can remain in existence. To understand one example of how this plays a role in modern physics do some reading (like in Wikipedia) on the topic of vacuum fluctuations (an effect of which is Hawking radiation), but it plays a rather general role in quantum field theory allowing Feynman diagrams (part of the calculation of the strengths of particle interations) that violate conservation of energy-momentum. This does not contradict the usual conservation of energy-momentum because the energy which appears out of nowhere does not last but disappears again with a short period of time, inversely proportional to the amount of energy involved: dt ~ h/dE.
What caution is necessary at this point is to say that despite the scientific/physics issues being disucussed here, the main postulate I am proposing, that these quantum scale energy conservation violations represent interaction with non-physical energy is not in any way shape or form any kind of physics or science. If the Copenhagen Interpretations of quantum physics (and the Everett Many Worlds Interpretation really changes nothing either) is correct then these events are fundamentally random and unpredictable, meaning what particular thing happens cannot be assigned any physical cause, for any such cause would be a hidden variable theory and this has been disproven by the failure Bell's inequality. Now certainly you can argue that a fringe minority of physicists continue to dispute this and continue to seek some way to restore physical determinism in a non-local formulation, but so far such attempts have yielded nothing, and all the judgements of the scientific method are in favor of the Copenhagen interpretation. But this lack of a physical cause for the details in some events leaves the way open for a philosopher or theologian to suggest the possibility for the role of non-physical causes in these events.
Q: Are you saying that energy conservation can be violated at the quantum scale, or only appear to be violated? The energy is still conserved, is it not?
Me: The classical law of conservation of energy is actually violated. This means that quantum physics reformulates this classical law to allow these exceptions in very short periods of time.
Energy is conserved in the long run but not in the short run. In very small periods of time energy can appear from nowhere as if there is a bank somewhere that physical processes can go to in order to get short term loans. In the case of vacuum fluctuations, particle and antiparticle appear out of nothing then annihilate and the energy vanishes back into the nothingness it came from. In the case of Hawking radiation it is the black hole that eventually pays back the energy loan by losing mass even though nothing is supposed to be able to escape from the black hole.
In 1944 Erwin Schrodinger wrote a tiny little book called "What is life?" In this book this famous quantum physicist makes the argument that quantum physics can have no impact on the process of life. However science at that time was just on the verge of discovering that scientists had made an enormous systematic oversight in the way it had been handling the more difficult mathematical problems that it routinely faces. This discovery would blow Schrodinger's argument out of the water. It is an interesting story because it was simutaneously discovered in many different branches of science from efforts to discover why mathematical calculations were failing to predict actual phenomena in many case. The culprit turned out to be the routine practice of getting solutions to non-linear equations by means of linear approximations. It was discovered that the non-linear equations had properties that the linear approximations did not. This was the birth of the science of chaos.
In linear equations small perturbations remain small and thus if they are random they will average out and have no effect on large scale phenomena. This was exactly the argument that Schrodinger used in his little book. But non-linear equations can amplify some small perturbations while damping out the others so that the perturbations do not average out and the large scale phenomena ends up being determined by the most insignificant happenings. This is the nature of so called butterfly effect, which says that the nonlinear equations governing the weather can amplify the movement of a single butterfly ignoring the movements of all the other butterflies so that what that one butterfly does ends up determining the weather patterns a week later on the other side of the world. A scientist by the name of Illya Prigogine managed to prove that the initial conditions of a system governed by nonlinear equations might actually have to be specified to an infinite degree of precision before the results could be predictable. But this means that quantum phenomena and events can no longer be ruled as insignificant in large scale phenomena when non-linear equations are involved.
The connection to life is made by a wonderful book by Erich Jantsch titled "The Self Organizing Universe" who shows how the properties non-linear equations provides the basis for self-organizing phenomenon in far from equillibrium systems. The book is a must read for anyone considering the possiblity of abiogenesis, for the book makes a very good case that the non-linear equations governing the behavior of many physcial systems naturally leads to type of self-organizing phenomenon that could lead to the development of life. I have become convinced that the development of life is such a self organizing phenomena that develops toward increasing non-linearity for it is by this process that such systems achieves the characteristic behavior of living things of acting independent of its environment. This increasing non-linearlity exploits a process of amplifying of quantum indeterminacy in order to provide the driving force of "evolution" (the progressive development of life from even before there was any RNA or DNA) and which is therefore the essense of life itself. What drives this development of life (and thus evolution) is a creative or upredictable response to environmental change known in the theory of evolution as variation.
The next step is to consider some rather fundamental but widespread misconcpetions concerning the theory of evolution itself. These are important because when corrected they profoundly change ones understanding of the nature of the process of life in general.
Q: If the misconceptions are for the purpose of discussion, please feel free, but if they are for my enlightenment, don't worry about it, unless of course, you wish to enlighten some of our peeps, like Dayton, for example, who really needs to understand those misconceptions.
Me: Well the kind of misconception about evolution that I am talking about is not the sort that Dayton or a creationist might have causing them to refute it, but the sort of misconception that an atheist might have. I came accross this in as study of mutagenesis where I discovered that damage to our DNA was something that was ocurring all time but that we have, even bacteria have a very efficient system of repairing all that damage. And then I found out that in studies of mutations in bacteria occurring as a result of damage from ultra-violet radiation, something very unusual was ocurring. A special molecule made by the bacterial would find and cover the damage to protect that damage to their DNA done by the radiation from their own DNA repair mechanism. When I read this, it became quite apparent that all those popular explanations of evolution that describe variation as coming from damage and mistakes were completely incorrect.
The point is that there is nothing accidental about the variation that drives evolution but that one part of the evolution of life is the development of inventive ways to create this variation. From a scientific point of view this is important because it means that this variation is NOT purely random but under the controls of the organism and the natural selection process to make sure that the types of variation produced are more likely to be productive rather than destructive. From this point of view, I think we can even see a correlation between periods in the history of evolution with an explosive generation of new diversity with the development of some new technique for introducing variations (that are more likely to be productive) into the genetic code. I believe that the development of sexual reproduction was one of the most important of these.
Anyway from the philosophical perspective, the point is that evolution is not something that simply happens to living things but something that living things do intentionally, and that creativity is part of the essential nature of life itself, which can ultimately be seen as deriving from this nonlinear amplification of quantum indeterminacy. Furthermore this is a nature of living things that goes beyond merely being a source of genetic variation but is part of this non-linear process by which self-organizing phenomena occurs in general. This is important because it means you can have a development of life in physical processes in other ways than the biological one based on the evolution of the genetic code. This is important in the next step, which is to see how the human mind can be another example of such a self-organizing physical phenomena, ocurring in the interaction and processing of information in the human brain.
