The best argument for compatibilism is empirical observation, and we can observe determinism and free will simultaneously in the same event:
When a person decides for themselves what they will do, according to their own goals and reasons, it is free will.
When a person decides for themselves what they will do, according to their own goals and reasons, it is determinism.
It is free will because they were free from coercion and undue influence, which is all that free will requires.
It is determinism because the choice was caused by goals and reasons that have a reliable history of prior causes, which is all that determinism requires.
Neither you nor Bruce Silverstein have been able to refute these simple facts.
It has been refuted. What we observe is not complete. We do not have access to the necessary information to form a more complete understanding of the system or make predictions on its fixed evolution.
We presume that the event was reliably caused by prior events which can theoretically be traced back in time to the Big Bang (and earlier if your cosmology permits). Determinism is not an issue to the compatibilist.
And given determinism, fixed evolution it is; no deviation, no alternate actions, no choice, no free will.
That claim is refuted twice, once as a false dichotomy, and once again as a contradiction of empirical reality.
That claim is refuted as a false dichotomy. Free will does not require freedom from all prior causes. It only requires freedom from coercion and undue influence, which are certain specific causes. Where coercion or undue influence apply, the choice is not freely made, and thus not free will. But when coercion and undue influence are absent, we are free to make the choice for ourselves, and it is free will. Because we find examples of both free choices and unfree choices within our deterministic universe, we must conclude that determinism does not rule out either event. And, because we get both entailment and free will, simultaneously in the same causally necessary event, there is no "either one or the other". So, the dichotomy is false.
The claim that choosing does not happen is empirically refuted by neuroscience, which affirms the brain's decision making function. And it is also empirically refuted by simply watching the people in a restaurant, browsing the menu and placing their orders. Each diner is logically reducing a literal menu of alternate possibilities to a single dinner order. The logical operation is choosing.
It is surface appearance. When someone orders a meal, there are no observers to the underlying process that brought about that action, not even the customer her or himself, where thoughts and feeling emerge into conscious mind in response to the information acquired from the menu...
If you like, we can locate our restaurant in a hotel hosting two annual conventions, a convention of neuroscientists and a convention of physicists. We may assume that either one or the other will have the most detailed understanding of the underlying mechanisms of choice. But the empirical events will remain the same. Each diner will be presented with a literal menu of alternate possibilities, each will choose for themselves what they will have for dinner, and each will tell their waiter their intent.
"I will have the Salad, please" says one. "I will have the Steak dinner, please", says another. All of them are adults with their own prior histories and their own reasons for ordering what they will order tonight. So, all of these orders are deterministically caused. None of the diners are coerced or unduly influenced to order something that goes against their own goals and their own reasoning. So, all of them are acting of their own free will.
And the waiters, empirically observing and writing down the orders, will later return to these diners with their meals, and the bill that they must pay before leaving.
We might wonder what other thoughts go through the heads of the neuroscientist as they are making their choice. Are they recalling the specific neural pathways involved in their own decision making? And we may wonder how the physicist interprets this event in terms of atomic interactions. Perhaps the waiters wonder why these diners seem to be taking longer to choose their dinners.
But, no matter, because they each still order their dinners, and each will responsibly pay the cashier on the way out. And this is all that is required for us to understand what free will and responsibility are about.
...or innate proclivities determining what is to be selected ahead of time, ie, you go in knowing exactly what you want.
Obviously, if I already know what I will order before I enter the restaurant, then I won't be looking at the menu. The "innate proclivity" would be the habit I acquired through my prior choices. On the other hand, if you're speaking of genetic dispositions for fat and protein, then those proclivities will not have any knowledge of what specific forms these substances take, but I will discover that over time by sampling different foods.
In any case, there can be no doubt that I actually can order any item on the menu, and that every item on the menu is a realizable alternative.
Of course you can order. In fact, if determined, you must order, if determined, you cannot will not not order (events fixed, no deviation)....yet at no point in time can will an alternate action be taken. That is according to your own definition of determinism.
It is never logically valid to force a "can" or a "cannot" into the definition of determinism. Please stop trying to do that and claiming it is my definition of determinism. It is not. It is dishonest to continually attribute that trope to me.
Determinism is not about what can and cannot happen. Determinism is about what will happen. Note the
corrections I've made in your statement above.
The events, of course, will always only happen one way, and will not happen any other way. But when speaking of how things can happen or could have happened, we are assuming the condition "If it had been determined another way".
IF it had been determined to happen another way, then it would have happened that way instead. Saying that we "could have done otherwise" never implies that we "would have done otherwise". In fact, when we say that we "could have" done something, we are logically implying that (a) we did not do it, and (b) that we only would have done it under different circumstances.
It is important to keep the distinction between what we "can" do and what we "will" do. There are always multiple things that we "can" do, but only a single thing that we "will" do. If we conflate the two, and insist that, we only can do what we will do, we create paradoxes. Such as this one, which you should know well by now:
Waiter: "What will you have for dinner tonight?"
Diner: "I don't know. What are my possibilities?"
Waiter: "Given determinism, there is only one possibility, and only one thing that you can order."
Diner: "Oh. Okay. Then what is the one thing that I can order?"
Waiter: "The one thing you can order is the same as the one thing you will order. So, if you tell me first what you will order, then I can tell you what you can order."
Diner: "But how can I tell you what I will order if I don't know what I can order?!"
That's been addressed a number of times.
No. It hasn't. If it had, then you could have simply cut-n-pasted your response here, instead of merely claiming it had been addressed.
The illusion is the perception that you could have taken any of the options on the menu at any point in time.
It is not an illusion. It is a fact that I could have taken any of the options on the menu at any point in time. It is also a fact that I would not have taken any other option at any point in time. Both are undeniable facts.
Choice requires the possibility of taking any one of a number of options,
There are multiple possibilities, corresponding to the multiple things that we can choose, but only one actuality, corresponding to the single thing that we will choose. If we conflate possibility with actuality, or conflate can with will, we create the paradox I described above.
The human species has evolved these two separate notions, and the distinct logic and language for each of them, in order to deal with matters of uncertainty. When we do not know what will actually happen, we imagine what can possibly happen, to better prepare for what does happen. For example, people expecting a hurricane will board up their windows, even though there is a slim chance that the hurricane will never hit their home.
while determinism only permits one: determined action, fixed by antecedents.
Determinism only permits one actuality. Determinism permits multiple possibilities, as we can easily see by looking at the restaurant menu.
However, it is a bit weak to say "permits". Determinism necessitates that there will be a single actuality. Determinism necessitates that there will be multiple possibilities.
Which is not a matter of choice, but entailment. Which is why the decision-making process in determinism is entailment.
Again, it is not an either entailment or choice, but both entailment and choice. Choosing is a real physical event that, like all events, is causally necessitated (entailed) by prior events.
Computers select options, not on the basis of will or free will, but straight-out information processing. What is selected is determined by the criteria.
So, you admit then that choosing is an actual event that takes place in physical reality. I'm glad we've settled that.
A Libet-styled experiment does not enlighten us on free will. It is quite sufficient that everyone understands what we mean when we ask "Were the student subjects required to participate in the experiment in order to pass the course, or did they choose to participate of their own free will?"
It shows that thoughts and actions are formed and generated prior to conscious representation and the will to act, that will is not the agency of thought and action, that nothing is being freely willed.
And there you are once again substituting "freedom from causation" and "freedom from our brain" for freedom from coercion and undue influence. Free will does not require freedom from our brain's normal decision making function. Such a requirement is irrational.
Free will only requires freedom from coercion and undue influence. Nothing more. Nothing less.
We observe people going about their business, responding to the world around them, their environment...which is precisely the evolutionary role and function of the brain. What we don't observe, and cannot observe, is the nature and the means by which all this is achieved.
Fortunately, we do not need to know the details of the how our brains work in order to determine who chose the Salad and who chose the Steak for dinner, and who is responsible for paying for each meal. In the restaurant, we can observe that no one was coerced or unduly influenced, and that each diner chose their dinner of their own free will, and is now responsible for their bill.
