P1: A freely chosen will is when someone chooses for themselves what they will do, while free of coercion and other forms of undue influence.
P2: A world is deterministic if every event is reliably caused by prior events.
P3: A freely chosen will is reliably caused by the person's own goals, reasons, or interests (with their prior causes).
P4: An unfree choice is reliably caused by coercion or undue influence (with their prior causes).
C: Therefore, the notion of a freely chosen will (and its opposite) is still meaningful within a fully deterministic world.
Will is not chosen, it is formed by unconscious processes in response to external stimuli. Information processing, not will, is the agent, the work of neural networks is not an example of free will.
The "external stimulus" is the restaurant menu. The specific "information processing" in response to that external stimulus is called "choosing". Choosing inputs two or more options from the menu, applies some criteria of evaluation, and outputs a single choice, such as "I will have the salad please". And the process is carried out upon our neural networks.
There is nothing in neuroscience that contradicts the fact that the brain is choosing from the menu what the person will order for dinner. The choice is reliably determined by the choosing process, so it is also consistent with causal necessity.
The term "free will" is used to distinguish cases where a person is free to make this choice for themselves versus those cases where the choice is imposed upon them by someone or something else. You know,
"P1: A freely chosen will is when someone chooses for themselves what they will do, while free of coercion and other forms of undue influence. "
This is the
operational definition of free will. The one that is actually used when assessing a person's responsibility for their actions. It requires nothing
supernatural. It makes no claims to being an
uncaused event. It simply does its job of distinguishing a deliberate act from a coerced act or an insane act or an act caused by hypnosis, etc. Whether it was an act of the person's freely chosen will or not is a matter of objective evidence, not a matter of illusions.
A label doesn't alter the status, state or condition of the system.
The brain is altering its own "status, state, and condition" as it moves from
reading the menu, to
considering its options, to
setting its intent upon having the chef salad for dinner, to
acting upon this intent by telling the waiter, "I will have the chef salad, please".
It is a deterministic process, one event leading to the next in a reliable chain of cause and effect.
The brain's task is to reduce the menu of alternate possibilities to a single dinner order. The process is called "choosing" or "deciding". And it is a normal function of every normal brain.
This is about the right kind of control to qualify as 'free will.' If you are not aware of something that is going on in your body, you are not in control of it. If a cancer is growing, you did not will it to happen. If your brain is malfunctioning, you did not will it to happen.
This is beyond the control of consciousness or will. If will lacks the right kind of control, it is not 'free will.'
The only control necessary is the ability to
read or scan the menu for options, the ability to
consider those options in terms of my own criteria, the ability to
choose the option that best satisfies my criteria, and the ability to
tell the waiter what I have decided that I will have for dinner.
That is the only kind of control needed for free will. The evidence of that control is the simple fact of my successfully performing each of those functions.
You create a
strawman by imagining that I must consciously choose the firing of each neuron in order to control what I will have for dinner. Obviously I do not have that kind of control. And, just as obviously, that imaginary kind of control is unnecessary to my choosing what I will have for dinner.
But that doesn't alter the fact that something drove you to rob banks.
The robber just needed some cash to pay off his gambling debts, and it seemed like robbing the bank would be the quickest way to get it.
Who plans to be a thief or a killer?
Al Capone, Jesse James, your local psychopathic serial killer, the drug companies pushing fentanyl. They all have specific plans.
Who plans to have a criminal record or spend their lives in a cell?
The plan usually includes not getting caught.
A combination of life, the world, their own circumstances and mental and physical makeup brings them down.
Of course. All events are reliably caused by something. But that cannot be used to excuse anything, because then it would excuse everything. So, causal necessity never excuses anything.
In fact, the more the behavior is ingrained by habitually being rewarded with cash for committing the robbery, the longer it will take to correct the behavior.
I don't see that you have demonstrated that you 'could have done otherwise.' It's just wordplay.
No wordplay. Just the actual meaning of the words. And I'm sure you use them yourself routinely in the way that I described. For example, if I were to say to you that "I had a salad for lunch. I could have had a cheese burger, but I had bacon and sausage for breakfast, so I decided to have the salad instead."
Does "I could have had a cheese burger" mean that I did have a cheeseburger? No, it doesn't.
Does it mean that it was possible for me to have had a cheeseburger? Yes, it does.
Does "I had a salad for lunch" contradict "I could have had a cheese burger"? No, it doesn't.
Determinism, by definition, doesn't allow ''could have done otherwise.''
Nope. Determinism, by definition, means "every event is reliably caused by prior events" (P2). The logical implication of this is that, given the same circumstances, determinism doesn't allow "would have done otherwise".
But a "could have done otherwise" will always be true whenever a choosing event occurs in the causal chain. The choosing event logically requires
at least two things that you can do. Thus, it will always be the case that you could have done otherwise, even if you never would have done otherwise.
Given a range of what we from our limited perspective call options or possibilities, there is only one realizable option per person in any given situation in any given instance in time.
What you fail to realize is that "realizable" falls into the same limited perspective as "options" and "possibilities". To realize (as used here) means to make it real. To be "realizable" means that is it possible to make it real, but not necessary that it will ever be made real.
Your option is one thing, your friends or family each have their determined option. Given determinism, nobody can do otherwise.
For the reasons above, which have been explained to you many times now, the correct statement is this: Given determinism nobody
will do otherwise (even though they
could have).
