Determinism/Free Will

To be clear, I do not take a fully libertarian stand and embrace free will. I am confident in saying there is no completely free will. I would say there is fettered will, restricted will. I feel there is an ability to exercise *some* choices not strictly bound by all previous events.

Is "will" synonymous with "choice" or am I conflating two separate ideas?

For myself, I don't see how it could be done. If you can think of way we can do this, please let me know.

So each of our lives, and humanity as a whole, shall only play out in one way? The future is written, we are just waiting to experience it?

You have defined "free-will" as uncaused. And since there's nothing uncaused, you can't be wrong. But, your argument depends on that definition of free will.

No. I'm saying we are caused to make certain choices for reasons or for no reasons. If for reasons, then our choice is determined by the reasons. If for no reasons, then our choice is random. You're free to define the mechanism that underlies "free will" that is based on neither reasons or no reasons. I've had a lot of these discussions and I've never heard a coherent answer.

There certainly is scientific support for part of your thesis in quantum mechanics. Determinism in the sense that one state of the universe must lead to a particular other state is false. As you mention, if we were to rewind the universe to it's original state, things may unfold differently. If we rewind the universe to the big bang and watch it all unfold again, quantum interactions may present a universe with different galaxies, different stars, and different things going on than happened in the universe we inhabit today.

I think you are right to invoke quantum mechanics as a way free will might be possible. This has become a favorite strategy of philosophers arguing the libertarian theory of free will. (BTW, "libertarianism" in metaphysics has nothing to do with the political libertarianism. It's just the same word being used to describe two different things.) There are two main theories in favor of free will: libertarianism or compatibilism. You are arguing libertarianism which I think is the better course to go. Libertarians recognize that there needs to be some physical force responsible for choice being a part of the causal chain. Compatibilists don't require this physical force, and I'm tempted to dismiss them on that account.

But we do have a problem, as others have already pointed out. Just because something is random does not mean that choice is involved. Let's go back to our example of rewinding the universe to the big bang and things unfolding differently. Sure, we have differently shaped galaxies and different star formations... but was choice involved in any of that? Obviously not.

As I mentioned in the other thread, determinism has been eschewed by contemporary philosophers in favor of the view "hard incompatibilism." Determinism in the classical sense (state A always leads to state B) has been proven false by scientists. So hard incompatibilists argue that choices are just another event that happens in our lives. And choices (like all other things) are determined solely by previous states and events. There is no definite outcome to a given state (because of quantum mechanics)... but quantum mechanics doesn't break cause and effect. It merely makes it "wavy." Cause and effect is expressed by a wave function rather than a Euclidean point A to point B line.

So in your thought experiment, we need to ask, "Why did I choose the door that I chose?" Imagine someone who has resolved beforehand to always choose door #3... no matter the number of doors. And if there are only two doors? Door #2. We have to consider this person because she still technically made a choice even though her resolution occurred prior to any doors being opened. The important question to ask is, "Why did she make the choice she made?" If causes beyond her control determined the choice she made, it is not a free choice, and it isn't free will.

Certainly it is with the kind of theological view of freewill I mentioned.

For the physical freewill, there's the unanswered question of how much randomness the quantum world brings to the macro world, such that it alters the ordinary course of cause+effect in a brain.

But nowhere that I'm aware of is there evidence of 'spirit', in some unexplained way independent (in its own decision-making workings) of cause+effect and randomness. If God exists, how does God make decisions independently of the innate decision-making processes of [his] own mind? That too can only be cause+effect or arbitrary, no?

There is God’s will, there is our will, and most of the time the two are in conflict. Thus, suffering is inevitable.

As for determinism in the material world, the most that can be accurately predicted - given sufficient information- is the probability of an outcome or occurrence.

Everything is connected, nothing is fixed, and in the final analysis no material thing has qualities except in it’s interactions, just as ‘no man is an island entire of himself’ (John Donne).

For sake of clarity, I suggest we forget randomness and focus on causation.

If, according to your instructions, I'm not free to define "free will" as having reasons (which implies causation), you're telling me that I'm limited to describing a free will choice as an uncaused event.

Suppose I choose to define a free will choice as an event caused by the ego's reasoning function of the brain. How have you ruled that out if not by defining "free will" as required to be an uncaused event.

It seems this concept of free will is heavily tied to religious philosophy. Perhaps Free Will is strictly a religious concept which requires a 'spirit' acting independently of the physical world, in which case, I would reject it as I take a Physicalist approach, with everything being physical or supervening upon the physical. If there are two forms of determinism, I believe my speculations are confined to the physically derived deterministic question.

Speaking solely of a physically deterministic cosmos, and setting aside lifeforms for the moment, do you consider all eventual future configurations of the cosmos's matter/energy to be strictly physically pre-determined by all previous causes and effects such that there will only be one possible configuration of the cosmos at any future point in time? Or are you saying that the future states of the cosmos may, or may not, be fixed, we simply have insufficient information to make a determination. If it is currently unknowable, do you lean one way or the other as to whether physical cause and effect results in a fixed or non-fixed future configuration of the cosmos?

You are, at least in the parlance of some philosophers.
"Free will" is seen as a basic concept and, as @AlexanderG pointed out, there is no such thing. On the physical level an event is either caused or random but there is no concept of freedom at that level. So, we have no free will.
"Free choice" is an emergent property of a complex brain, capable of conscience. As long as you stay on that level of complexity, you can say, you have free choice - but never try to reduce it to the physical level or you'll lose it.

Let's go back to our example of rewinding the universe to the big bang and things unfolding differently. Sure, we have differently shaped galaxies and different star formations... but was choice involved in any of that? Obviously not.

Indeed, no choice is involved with the unfolding of the cosmos as there is no deciding agent. It is simply the unfolding of random interactions, these interactions being governed by the properties of matter/energy.

And choices (like all other things) are determined solely by previous states and events.

And the position here then would be that there is no such thing as choice? The apparent choice is strictly the determined outcome of previous events?

There is no definite outcome to a given state (because of quantum mechanics)... but quantum mechanics doesn't break cause and effect. It merely makes it "wavy." Cause and effect is expressed by a wave function rather than a Euclidean point A to point B line.

A wave function seems to indicate some type of uniformity, predictability. Does that mean that matter/energy interaction are not random but flow in some pattern?

So in your thought experiment, we need to ask, "Why did I choose the door that I chose?" Imagine someone who has resolved beforehand to always choose door #3... no matter the number of doors. And if there are only two doors? Door #2. We have to consider this person because she still technically made a choice even though her resolution occurred prior to any doors being opened. The important question to ask is, "Why did she make the choice she made?" If causes beyond her control determined the choice she made, it is not a free choice, and it isn't free will.

My speculated position is that the near future appears fully physically deterministic. Each present is fully informed by the causal chain. What I am trying to tease out, is whether or not there are some instances in which a choice is made between options (options not unlimited, but determined, informed by, the causal chain of events) that is not strictly dictated by previous events. You seem to describe this as having control. No control whatsoever, means no choice, means no free will. The converse being full control, resulting in true choice and the existence of complete free will.

Can there be a middle ground? A state of partial control? Would this indicate some capacity to choose, if not entirely freely, a limited choice?

In my first thought experiment in which every room is identical, when our test subject make the first choice, if she truly had no independent control we would expect that she must always make the exact same choice every single time. Do you think this is the case? I am skeptical that each reset of initial conditions and reinitiating the choice scenario would result in that first choice always being the same. If it would not always be the same choice, does this necessarily indicate there is control involved?

I appreciate you making this distinction for me. Given this distinction I too would conclude there is no Free Will as conceived in Philosophy.

It has certainly been used there, not least to excuse God from having any obligations to do anything practical on the ground that [he]'s withdrawn so that our will can be freely exercised. As as routinely been pointed out in reply, respect for the free will of the criminal is by its very nature disrespect for the freewill of the criminal's victims, but the notion doesn't seem to have altogether gone away.
If there are two forms of determinism, I believe my speculations are confined to the physically derived deterministic question.
The first one I mentioned can only arise within a particular kind of theology, one with an omnipotent omniscient perfect God. A theology without such a God would not have a problem of that kind.

The cosmos, like the humans in it, is made of matter and energy. The future states of the cosmos (from what we know at this particular time) will depend on the power of quantum randomness to interfere with relevant chains of strict cause and effect. Beyond that I can't say, though others closer to the game may have a clearer view.

Future depends on so many things. On the movement of magma beneath the surface of earth, on the size of asteroids that impact the earth. There is not much that we can do about it.

If we had enough information, we could trace all our choices back to the Big Bang, So, if one defines "free will" as an uncaused event, it doesn't exist. But what does the prisoner lose when he's put into solitary?

Certainly, there is quite a lot we have no control over. Are there some things we do have control over?

Thinking about big systems, have we had, and do we continue to have control over how much CO2 we expend in the atmosphere?

The universe is non deterministic in two ways. First through quantum randomness and second through chaos. I think you are vaguely familiar with quantum randomness, aren't you?
Chaos results from quantisation in another way. Not only are we not able to measure things to an arbitrary precision, but things in the universe can't be arbitrarily precise. Through this imprecision chaos results.

Part 2
If there is an element of randomness to the cosmos and the future is not inevitably pre-determined by past events, what role may this play in our ability to exercise Free Will? One way this element of randomness may effect us, we human beings, is in the way biology and prior events shape who we are at any specific moment. Consider identical twins, both starting as single fertilized eggs in the same mothers womb. We know from experience that no two identical twins are exactly the same, either physically or mentally. Yes, they may share many similarities but they are quite distinct. You may object and say that even though the two fertilized eggs ostensibly have the same genetic material, there is always the possibility that even at the single cell stage, there is some difference, they are not molecule for molecule identical. I think this is a valid point and I assume to be exactly the case. But even still, whether they are 99.9999 percent identical or 99.99 percent identical, I would suspect that we would see stronger physiological duplication if some element of randomness was not injected into the development process. This is my conjecture and I could be completely wrong. However, my conclusion is that randomness of the cosmos plays a role in our development and our existence on the whole such that our futures are not pre-determined. Not by biology, nor by our cumulative experiences, or the causal chain of the cosmos.

So now the question becomes, if the future is not set, are we able to make an unimpeded choice in this random universe, a choice not strictly dictated by previous events. To test this, I have devised a thought experiment. Let's imagine that we have a maze of rooms. Each room is identical in dimension, material, and color. Each room has an entrance door in the middle of one wall, and five identical doors in appearance on the wall opposite the entrance door. Each door leads to another room that is identical to all others. Once entering a room, you cannot go back, but must choose to remain in the current room, or choose one of the five doors to exit. Once a door is opened, all other doors lock and are no longer an option. Lets run an imagined experiment through the maze with ourselves as the test subject. We are tasked with entering the maze and traversing through 1,000 rooms (lets put aside biological needs during the test, it is an imaginary test after all :) ).

So here we have a test of choice where we are presented with a series of 1,000 identical choices. Imagine that we were able to run the experiment multiple times, such that we could reset initial conditions, go back in time if you will, and the subject (ourselves in this case) had no knowledge of repeating, that each run was experienced as being the first. Do we expect each run of a thousand choices to be exactly the same? Even if we start out with some system of choice, say starting from left to right, first room we choose is farthest left door, next room we choose the one to the right of farthest left, and so on. How long would we keep this up? Would we begin to mix it up? Would we get bored eventually and start always choosing the same door just to get the experiment over? At what iteration of rooms would these changes to attacking the problem occur? If, on the first run we hold the pattern of left to right choice for 20 rooms, for each run of the experiment, will we always end the pattern on the 20th room? Will we always start with that particular pattern? What iteration of room do we become bored? The 50th? The 173rd? Will our boredom arrive at the exact same point for each run of the experiment? My guess is no, they will not. Each run of the experiment will result in a different pattern of choices for the 1,000 rooms, even starting at identical initial conditions. I would suggest, that the mere time involved in considering our options, weighing our choices, playing things our in our mind before action is taken, all this delay, this amount of time, allows the randomness of the cosmos to exert some influence. If the choice is identical, we have an expanded ability in which we can choose freely.

We can play with this setup. We can make it such that for the 3 most left doors, there is always something unpleasant in the room beyond, and for every 2 most right doors, there is always something pleasant. Over time, we will realize this pattern and I expect this experience will influence our choices such that (for some of us anyway) we begin to only select the 2 most right doors. This would be an example of how past events influence choice even though we have freedom of choice. I can also imagine that given a long enough period of going through rooms, we might become curious as to whether the pattern of unpleasant rooms and pleasant rooms still holds. We may take a chance and pick one of the 3 left side doors. We find that it is unpleasant and it confirms in us that the pattern has not yet changed. At what iteration of rooms do we take that chance of exploring the 3 left doors again? In multiple runs of the experiment, will we take that chance at exactly the same iteration? On some runs may we never take that chance? My guess is that it will be different for each run of the experiment, to include some runs where the choice to chance the left doors again never comes.

If no two runs in both types of experiments will result in identical patterns of choice, does this indicate that there is at least some freedom to choose? I would say yes. I would say that we human beings do not have complete freedom of choice whereby any presented choice is in no way influenced by past events and experiences. I would posit that we have a limited or restricted capacity to exercise our will. Our unique neural patterns of our central nervous system creates limits, or more precisely, influences upon how we will decide any given choice. Past experience certainly influences how we decide any given choice. Of course, the choices we are even presented are dictated by all causal events leading up to the present choice. But despite all those factors narrowing and limiting how we might choose in any given circumstance, I feel that there can still be some serendipity, some expression of whim, in the exercising of some choices, and I based that idea on the speculations presented in the thought experiment. We, I surmise, are not going to do the very exact same thing, every single time, dictated strictly upon all previous causal chains.

I have one other idea as well. I think our capacity to imagine breaks causal chains. The fact that we can know that past causes lead to current events allows us to realize that changing conditions will impact future events. Our imagination however can create events within the rules of nature that are possible, yet have never happened. We can also mix and match our past experiences in a way to imagine things that are not probable or even possible. If we are making choices about our future actions, and those choices are informed by imagination instead of the present state of affairs, are we not making free choices in that instance? Certainly our past experience has influence, yet I see us as inventing choices to a degree as opposed to simply reacting to current conditions. This seems another possible expression of free will.

What do you think? Have I made a case for some modicum of free will? At the very least, I think I have a good argument to claim that the future is not set in stone. Would you agree?

I'm glad that I just take for granted that we have a will which can choose, however freely that may or may not be, OR as some might say, I have swallowed the illusion hook, line and sinker.

How can we trace all our choices back to the big bang when animals with some sort of will about what they will do did not come on the scene until relatively recently.

The first one you mentioned gives no problems for the Bible God because it is a crazy argument which denies the possibility that the Bible God can know what we will freely choose.
If He knows what we will freely choose then we are freely choosing it even if God knows what it will be.
