... The term ''Free Will'' has its roots in Christianity;
''The term "free will" (
liberum arbitrium) was introduced by Christian philosophy (4th century CE). It has traditionally meant (until the Enlightenment proposed its own meanings) lack of necessity in human will,
[10] so that "the will is free" meant "the will does not have to be such as it is". This requirement was universally embraced by both incompatibilists and compatibilists.
[11]'' - Wiki
And yet, just above that paragraph you have this one:
The problem of free will has been identified in ancient Greek philosophical literature. The notion of compatibilist free will has been attributed to both Aristotle (fourth century BCE) and Epictetus (1st century CE); "it was the fact that nothing hindered us from doing or choosing something that made us have control over them".[4][9] According to Susanne Bobzien, the notion of incompatibilist free will is perhaps first identified in the works of Alexander of Aphrodisias (third century CE); "what makes us have control over things is the fact that we are causally undetermined in our decision and thus can freely decide between doing/choosing or not doing/choosing them".
Wikipedia actually has another, separate article called
Free Will in Antiquity that lists even earlier contributors to the notions of determinism, compatibilism, and libertarian viewpoints.

Yes. Every event is the reliable result of prior events, and is thus causally necessary/inevitable from any prior point in time. This includes the events of experiencing a desire, foreseeing the consequences of an action, and forming an intention to act on that desire. And I presume perfectly reliable cause and effect, even at the quantum level.
Yes, and as always, the sticky point for compatibilism lies in agency and the defining freedom as acting in accordance with ones inclinations despite the fact that acting in accordance with one's inclinations is necessitated, not chosen....actions initiated before milliseconds prior to awareness.
Nothing sticky about it.
a) Either you made the choice, or, someone or something else made the choice.
b) If you made the choice unconsciously, then it is still you making the choice. And the unconscious brain will inform the conscious brain in plenty of time to tell the waiter, "I'll have the steak dinner, please".
c) By causal necessity, it would be you, and no one else that would make that choice at that specific time and place.
But, perhaps it is still sticky for you. I hope you can see now how easily it sorts itself out.
The questions are:
"What does this fact of causal necessity of all events logically entail?" Pretty much nothing. It's just a background constant which is logically true within any world of reliable cause and effect.
"How does this fact of causal necessity affect our notion of freedom?" It has no affect whatsoever.
"Does this fact of causal necessity entail that we have no free will?" Nope. You would have to come up with a special definition of free will, such as "a choice we make that is free of causal necessity", in order for anyone to conclude that it conflicts with free will.
Cognition is more than 'just a background constant.' It's the very means by which we think and respond, what we think and the actions we take. The state of the system equates to the nature of the action.
Cognition is a causal mechanism. Causal necessity is the background constant.
The cognitive process causes choices to be made and actions to be taken. Each of us comes into the world equipped with this causal mechanism, called the central nervous system. It enables us to be the causes events. And it gives us executive control, because we decide what happens next.
Again, none of this is willed. It's an unconscious process right up to the moment of conscious report. Not being willed, it has nothing to do with free will.
So what? Conscious or unconscious, choices are still our own choices.
''The results show that, first, W is not strongly linked to the time of movement onset, so whatever is going on in the brain at time W cannot be responsible for movement genesis.

Moreover, the brain event of W may even be later than we subjectively report. This should not be a complete surprise since humans “live in the past”—certainly perception of a real-world event has to be subsequent to its actual occurrence, since it takes time (albeit very little time) for the brain to process sensory information about the event. A recent experiment showed that it was possible to manipulate the conscious awareness of willing a movement by delivering a transcranial magnetic stimulus to the area of the brain just in front of the supplementary motor area after the movement had already occurred.3 This suggests that the brain events of W may occur even after the movement.
Yeah. We know all of that stuff. And it doesn't change anything. The conversion of sensory data into conscious awareness takes a wee bit of time (you know, turning the image right side up, and all that). And a normal brain can be manipulated by transcranial magnetic stimulus to give us inaccurate sensations.
Free will remains a choice we make for ourselves while free of coercion and undue influence. There is nothing in neuroscience that contradicts this.
If free will does not generate movement, what does?
''Movement generation seems to come largely from the primary motor cortex, and its input comes primarily from premotor cortices, parts of the frontal lobe just in front of the primary motor cortex. The premotor cortices receive input from most of the brain, especially the sensory cortices (which process information from our senses), limbic cortices (the emotional part of the brain), and the prefrontal cortex (which handles many cognitive processes). If the inputs from various neurons “compete,” eventually one input wins, leading to a final behavior. For example, take the case of saccadic eye movements, quick target-directed eye movements. Adding even a small amount of electrical stimulation in different small brain areas can lead to a monkey's making eye movements in a different direction than might have been expected on the basis of simultaneous visual cues.4 In general, the more we know about the various influences on the motor cortex, the better we can predict what a person will do.''
You keep repeating this as if it had something to do with free will. I shouldn't blame you since you are quoting from authors who are looking for free will in the primary motor cortex, and equating "quick target-directed eye movements" with a person's choice as to whether he should rob a bank. This is foolishness.
Again, nobody is arguing that ''causal necessity is some kind of entity that exercises control over us'' - that is Strawman. Nobody has said it, nobody argues that causal necessity is an entity.
Well, let's see how long it takes before you do it again.
The question is just whether freedom of will is compatible with determinism. And seeing the standard definition of determinism happens to be - Determinism: The world is governed by (or is under the sway of) determinism if and only if, given a specified way things are at a time t, the way things go thereafter is fixed as a matter of natural law. - the answer is clearly no.
And there it is. Determinism is presented to us literally as a "governing" force that exercises some kind of "sway" over events.
The answer is no because the very definition of freedom is regulative control or the absence of necessity, coercion or constraint in choice or action.
Freedom is the ability to do something that we want to do. We are not free if we must do something out of necessity whether we want to or not. We are not free if we are coerced by someone with a gun to do something whether we want to or not. We are not free if we are constrained from doing what we want to do or constrained to do something that we do not want to do.
But, logically, if what we want to do is causally necessary, then causal necessity cannot be said to prevent us from doing what we want, having provided that want in the first place. Any constraint, upon doing what we want, would have to come from something else, like the guy holding the gun.
Yet the very means of thought and action is deterministically necessitated, all decisions are necessitated with an option to do otherwise being impossible.
Except that each option to do otherwise will, by causal necessity, appear to our mind via a real physical event within the brain's real processing as part of the rational causal mechanism, the real mechanics of thought.
Where then is free will to be found?
Right there. I just showed it to you again! It's in the mechanics of thought that enable you to construct your own argument.
It seems, only within a definition that seeks to redefine freedom in order to support the notion of 'free will'
Ah, but it is you that argues for a flawed, straw man definition of freedom. One that requires freedom from cause and effect, as if cause and effect were some kind of boogeyman that would steal our control and our freedom. There is no freedom without reliable cause and effect. So, the philosophical definition of free will, as "freedom from causal necessity", is an oxymoron, a paradox created by self-contradiction.
The correct notion is this: free will is when someone decides for themselves what they will do, while free of coercion and undue influence. That is the notion that is used when assessing a person's moral or legal responsibility for their actions. This sort of free will is commonly understood and correctly applied by most people.
The notion of being "free from causal necessity" can never be used to excuse someone from responsibility, because if it excuses one act then it excuses all acts, because all actions are equally causally necessary.
'I would have done otherwise, if I had wanted to', or 'I could have wanted otherwise' is impossible when determined actions inevitably follow from deterministically realized options, with will playing no part in regulation.
Sorry, but "I could have done otherwise" is hard coded into the rational causal mechanism. You cannot declare it to be "impossible" without breaking rationality itself.
The survival benefits of intelligence comes from imagining alternate solutions to environmental challenges. Intelligence gives us the ability to deal with matters of uncertainty. And, lacking omniscience, we are often confronted with uncertainty.
For example, its morning, and I wake up hungry. What will I have for breakfast? Well, what can I have for breakfast? I have eggs is the fridge. So, I am certain that I can fix eggs. But, I'm still uncertain as to whether I will fix eggs. What other options do I have? Hey, here's some pancake mix in the cupboard. So, I am also certain that I can fix pancakes. But I am still uncertain which one I will fix. Well, what did I have for breakfast yesterday? Hmm. Eggs. What about the day before yesterday? Eggs. And the day before that I also had eggs. So, just for a change, I will have pancakes this morning for breakfast. Could I have had eggs instead? Yes, of course I could.
As you should see by now, that fact that I
would not have eggs does
not logically imply that I
could not have had eggs.
What I "can" do
constrains what I "will" do. I "will" never do something that I "cannot" do.
But what I "will" do
never constrains what I "can" do. What I "can" do is only constrained by my imagination.
