Like I said in my last post, I like the strategy you're employing. I'm not a fan of looking at AlexanderG's argument (which was something like,"either something is random or it's for reasons") and calling it a day as far as free will goes. I think AlexanderG says something significant, and probably true, but I think it's the starting point for the debate rather than a fitting closing statement. There are responses one could make to AlexanderG, and there are other arguments, besides the one presented by AlexanderG that persuade me to reject free will.
I agree entirely. However, as you say, AlexanderG is describing a real phenomenon, or expression of the properties of the cosmos. To my mind, it might be best to give this its own name and acknowledgement, and then define or describe its role in the human decision-making process.
My suggestion would be vector determinism, or vector physical determinism. This would encompass the causal chains of physical interactions, be it at the atomic level or gravitational interaction of massive bodies. And as you say, this is the starting point, this is the physical environment in which we operate and make our choices. We must then determine whether the choices we make strictly adhere to vector physical determinism (awkward wording, I know) or if there is something additional going on.
At the very least I would want to work out what is meant by "reason" as AlexanderG means it. It is a famously vague word. You could talk about the "reason" the earth is the temperature that it is. And there are a multitude of reasons in this case: its distance from the sun, the temperature of the sun itself, atmospheric conditions that better allow the Earth to retain heat etc.
We also use the term "reason" to disclose our purposes: "Is there a reason you didn't put the shovel back in the toolshed?" -- "Yes. I wanted to work in the garden tomorrow, and I didn't feel like going all the way to the toolshed just to get it."
Another way we might employ "reason" and this is what I think AlexanderG meant, is, "the support for making one choice over another." And it's worth mulling over exactly what we mean by support. If I go to my fridge and choose one beer over another, I might have logical reasons for doing so. Maybe I want to save the good beer for when a friend visits. So, in this case I selected one beer over another according to a pure calculus of desired outcomes.
But I may not involve logic at all when selecting a beer. Sometimes my choice boils down to "whatever I feel like choosing at the time." But this ultimately involves my inner urges and appetites. "I want the beer that I crave right now." I imagine tasting one (the IPA) and the other (the lager). And I make my choice based on which one seems most appealing to my tastebuds.
Nicely laid out. I agree.
...
I think we can safely say that part of the brain does not have free will, and may even run interference on free will, if free will happens to exist in some modicum.
...
I certainly agree, and hopefully my comments have indicated that.
...To me, "reason" insofar as "support for one decision over another" doesn't play a substantial role in the reality of free will. But what DOES interest me, as far as free will goes, are the laws of nature, the physical states of the universe, and what must necessarily proceed from the former and the latter. And how these things particularly affect free will.
Given the quote preceding this one, should we even be referencing "Free Will" or "free will" at this point? We seem to have rejected the concept, at least in a staunch libertarian sense. At the same time, we have a strong sense that there is more at play than my coined phrase "vector physical determinism" or whatever appropriate term you would like to use in its place.
The word 'will' still seems relevant, but it is used as verb forms as well as a noun and can reference more that choice, such as desire or determination. The word 'volition' seems to have a more narrow usage as a noun, the power or act of making a choice or decision.
Should we consider changing the words we use?
As to the sentiment of this quote, I agree with you and feel it is reflected in my comments thus far.
...If you want to argue libertarianism or hard incompatibilism (two conflicting theories).
No, not really. I'm ready to set both aside and take a fresh look at things.
This comment brings to mind debates such as "Nature vs Nurture" or "A Priori vs Tabula Rasa". The human organism is much more complex than such stark dichotomies. We realize now that we human beings are a product of both nature and nurture, and that we have limited pre-wired instinctual behaviors as well as a great ignorance of the reality of the world which must be learned through experience from the moment we are born. I think this holds true for human volition as well.
A libertarian says that deterministic systems exist in the universe, and no free choice exists within them.
Would you say that this corresponds to my concept of "vector physical determinism"? Do we need the adjective "free". or can we simply say "no choice"?
But, according to libertarians, there is room for the possibility of free choice (not solid proof of free choice, mind you, but room for the possibility) when we understand that the universe is not completely deterministic, as QM demonstrates plainly. I think this is one of your main points (ie. something you agree with) but perhaps we should clarify this before proceeding.
This first hurdle is whether there is such a thing as choice. Absent life, is it safe to say that the cosmos proceeds in a strictly deterministic way (my vector physical determinism, to be consistent) and there is no choice whatsoever in such a system? Interactions are governed by natural laws (an acceptable term?) such that outcomes of events are governed by these laws.
Is a simple computer no different? Does the programing simply become additional laws that further govern interaction on top of the natural laws, such that there is no true 'choice' being made, simply the expression of natural laws and laws added by the computer?
Is the algorithm of life, encoded in DNA, simply another rule set added to the existing Natural Law rules that govern physical interactions such that 'choice' still does not exist?
Add in the organic based biological computers of organisms with a CNS. Is it simply more rule sets added to Natural Law, bound to strict physical determinism and 'choice' continues to not exist?
When, then, does volition exist? If it can exist, what enables it? I'm of the opinion that volition does exist and human beings can express it to some extent. I think you agree. I do not think that the volition we posses is by any means free or unencumbered. I think you may agree with that also, but I'll let you state your position directly.
Now we need to find the cause of volition and the extent to which it can be exercised.
THE CONSEQUENCE ARGUMENT:
(1) There is nothing we can now do to change the past.
(2) There is nothing we can now do to change the laws of nature.
(3) There is nothing we can now do to change the past and the laws of
nature.
(4) If determinism is true, our present actions are necessary consequences
of the past and the laws of nature. (That is, it must be the case that, given
the past and the laws of nature, our present actions occur.)
(5) Therefore, there is nothing we can now do to change the fact that our
present actions occur.
-- Robert Kane, Four Views on Free Will
I am in full agreement with statement (1).
I agree with statement (2), but given my comments above, it begs the question "Can we add to the Laws of Nature?". Or more precisely perhaps, can algorithms be created within Natural Law, either through random interaction or volition, that create additional rules that would not be present otherwise, and all such rule sets in concert affect the system.
For statement (3), the issues raised in (2) apply.
For statement (4) I would ask whether determinism applies universally, or only under certain conditions. For that matter, is there more than one kind of determinism, in which case, one would need to know how many and determine if all types always have influence or if certain conditions are required for some types of determinism to occur. I think we have identified one type of determinism, vector physical determinism (yes, I have to use this phrase until you give me another), and it remains as to whether we can establish others or if it applies universally.
My concern with both statements (4) and (5) is they address only the past and present and not the future. When we talk about choice or volition, we are talking about affecting the future. I disagree with this notion that "there is nothing we can do now to change the fact that our present actions occur." Technically it is correct in a sense, and as I have described in my comments, that in very short time intervals the cosmos appears strictly deterministic. There is very little time in which dramatic change will occur to alter the course of events. However, each present is a realized future. We cannot change the present in the present, but can we change future presents through volition? I say yes. Does this make sense? The Consequence Argument fails to take in the totality of what is occurring, in my opinion.
I shall leave things here and await your reply.
EDIT: What about the term "Billiard Ball Determinism" as a replacement for "Vector Physical Determinism"?
