The objectivity of divine law is real.
In a sense, I suppose you could say that the uncertainty principle is some sort of a non-deterministic microlocal cause for a violation of the conservation of energy and creation of the particle antiparticle pair. I was thinking of causality in a deterministic sense that if A causes B, then A must always be followed by B. In the quantum world we know that identical conditions may give rise to a variety of different events along a stochastic probability distribution.I’m still reading through your sources, but I don’t understand how what you’ve pointed out even in principle undermines the concept of efficient causality. It seems as though it simply proves is that there is non-deterministic causality. Any good theist who believes in free will would say that same.
Physics does not answer what energy is, because it can not explain the nature of motion. Ontology will explain that matter can not move itself, and motion is explained as a capacity for change to the actual changing, or potency to act. The capacity for change, or fulfillment, can not move itself to change or to fulfillement, but must be moved by an exterior agent that causes the change, or fulfillment (act) Pure energy(or force) is pure act, and pure act is God.Right. The production of the particle antiparticle pair comes about not because of deterministic causality, but because of quantum indeterminism given by the uncertainty principle. Before the particle antiparticle creation, the energy in the vacuum was E(0) say. But because of the quantum theory uncertainty principle there will be an increase in energy of the order of dE = (h/2pi)/dt over a very short period of time. So the energy increases from E(0) to E(0) + dE, not by any deterministic causal principle, but by quantum uncertainty which arises because of the statistical nature of quantum mechanics.
Self evident principles are not evident to some, the principle of contradiction does not apply for some, and neither does you can’t give what you do not have. When applying these principles to the quantum theory, the theory can not stand. More energy coming from less energy, things pop in and out of existence, no certainty causing possibilities, almost a departure from objective reasoning, like I said a lot of subjective thinking with error. Using math to explain reality, by formula.In a sense, I suppose you could say that the uncertainty principle is some sort of a non-deterministic microlocal cause for a violation of the conservation of energy and creation of the particle antiparticle pair.

Of course, you also have a violation of Bell’s inequalities in the quantum theory which implies that nature is incompatible with local causal realism. Generally, it is thought that quantum theory would become causal only by adding hidden variables, which is ruled out by Bell’s theorem. Phenomena such as radioactive decay, photon emission and absorption, and many others are such that only a probabilistic description of them can be given.
But then again, you can argue for a weak non-deterministic version of causality.
There is a recent paper by Xian O. Camanho, Jose D. Edelstein, Juan Maldacena, Alexander Zhiboedov which argues that there is a high energy scattering process which leads to causality violation.

Getting back to the Kalam argument, do you think it is provable that the universe itself, as a whole, has a Newtonian or deterministic cause? Or if you allow weaker non-deterministic and probabilistic causes, could it have arrived as a result of a quantum fluctuation?
Also, not much is known about before the BB, so it is not obvious to a lot of people that the universe had a beginning.
Why would A always be followed by B? If A is a sufficient rather than both a necessary and sufficient condition, then I don’t see any problem. All that matters with, say, the principle of finality (a corollary of the principle of causality) is that a potential is a potential for an effect or range of effects. The potential will not, when actualized, give rise to something it didn’t have the potential for. It does no damage to say that one potential can give rise to different actualities. This kind of non-determinism is even broader, it seems, than probabilistic conceptions. With the example of free will, at least in the Thomistic account, our choices are not based upon chance itself (I’m not certain that chance even has any kind of causal power anyway, but more on that below), even if they aren’t determined beforehand.In a sense, I suppose you could say that the uncertainty principle is some sort of a non-deterministic microlocal cause for a violation of the conservation of energy and creation of the particle antiparticle pair.

I assume what you’re saying is that “all things being equal” is a certain proposition, not merely one which says “all detectable things being equal.” So we’ve ruled out hidden variables, which means that the same set of circumstances bring about different results in different instances. That just means the potencies in things pertinent to quantum fluctuations are variegated. I’m not convinced this does any damage to the principle of causality any more than free will does.Of course, you also have a violation of Bell’s inequalities in the quantum theory which implies that nature is incompatible with local causal realism.

You’re going to have to unpack the basic conclusion for me. I’ve never been good at mathematics.But then again, you can argue for a weak non-deterministic version of causality.

From the perspective of classical Thomist philosophy, it’s not demonstrable by reason alone that the universe had a beginning. Some contemporary Thomists say that the Kalam argument can be reconciled with classical Thomism, but I have not investigated the issue myself, and I have no stake in it – at least for the reason that it’s not necessary for proving God’s existence. Again, I don’t understand how quantum mechanics negates certain kinds of causality which, say, are the foundation for theistic arguments for God’s existence. It seems that quantum mechanics merely positively asserts that there are certain kinds of non-deterministic causality on very small scales. It is altogether a very different assertion to say that the causality of macroscopic proportions is entirely reducible to causality on smaller scales. That would involve an investigation into essentialism, irreducibility, and the like.Getting back to the Kalam argument, do you think it is provable that the universe itself, as a whole, has a Newtonian or deterministic cause? Or if you allow weaker non-deterministic and probabilistic causes, could it have arrived as a result of a quantum fluctuation?

I think that physics tells us that energy is the capacity to do work. Generally, there are three types of energy, heat, kinetic and potential energy.Physics does not answer what energy is,…
I changed myself by learning French on my own. This change enabled me to communicate while in France and Belgium.Change is caused by another, matter can not change itself, because it can not move itself.
Yep. You initiated a course of events.I changed myself by learning French on my own. This change enabled me to communicate while in France and Belgium.
But your potential to learn French did not cause itself to become actual.I changed myself by learning French on my own. This change enabled me to communicate while in France and Belgium.
AFAIK, there is no physical theory which is an absolute fact. The value of a physical theory depends on both the success with which it explains a wide range of presently known facts and its usefulness in suggesting places to look for presently unexplained phenomena. Physical theories are tentative and can be corrected or modified depending on experimental results. However, the quantum theory and the theory of relativity have both been hugely successful and valuable in describing physical phenomena. Of course, today we see many physicists working on string theory in an attempt to unify the two theories on both the large and the small scale.Remember you are treating the theories of quantum mechanics as fact, and they are not.
To answer that, I need to know what you mean by cause. Some people will define cause weakly, others will define it strongly.In the meantime disprove that things that come into existence must have a cause, show the the error in logic, or reasoning.
Generally, motion is a change in position of an object with respect to time. Motion can be described in terms of displacement, distance, velocity, acceleration, time and speed.To observe the motion of a body you need to attach a frame of reference and measure the change in position of the body relative to that frame.Physics never answers what is … the nature of motion., they are stuck at ground level.
I am not sure that that is true in every sense of the phrase, although it will be true in a lot of cases. For example, suppose that I am not fluent in French, but I spend time teaching my neighbor the French language and he becomes fluent in it. So I was not fluent, but my student did become fluent by means of my teaching him the subject.you can’t give what you do not have.
I thought that the question was whether or not something could change itself. Is it yes or no?But your potential to learn French did not cause itself to become actual.
The principle of causality simply implies that potentials do not cause themselves inasmuch as they are potential; for inasmuch as they are potential, they do not exist in actuality. Causes which are not actually existent do not produce actually existent effects.
We can because we have free will. Otherwise it is determined.I thought that the question was whether or not something could change itself. Is it yes or no?
Then that kills the Kalam argument which assumes such. Or, if not kill, it at least reduces the Kalam argument to speculation.From the perspective of classical Thomist philosophy, it’s not demonstrable by reason alone that the universe had a beginning.
As secondary causes, not the primary cause of power (Pure Act) A capacity to do work is not the doing, it is only a potential, a potential is not an act, the act is the doing’ and the potential for work, a capacity can not fill itself, but must be filled (moved) by another to become an act(work) We take things for granted because those who represent authorities say so, as if they can’t be wrong, or questioned What does it profit a person to eat a meal that someone else has digested…I think that physics tells us that energy is the capacity to do work. Generally, there are three types of energy, heat, kinetic and potential energy.
I am not sure what you mean. Do you mean the scholastic Aristotelian type philosophy that was digested during the Dark Ages?What does it profit a person to eat a meal that someone else has digested…
And what does that matter if there are arguments based on more basic principles?Then that kills the Kalam argument which assumes such. Or, if not kill, it at least reduces the Kalam argument to speculation.
