The compatibilist proposition is simply that free will is a meaningful concept within a deterministic world.
The proof is this:
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.
Information acts upon the brain upon which the brain produces an action which is brought to mind.
The brain acts upon the information. To say that the "information acts upon the brain" creates another imaginary causal agent. The restaurant menu lists the meals that the chef is able to prepare for us. But the menu does not force us to choose any of the listed items.
Each person is free to choose for themselves what they will have for dinner.
''The compatibilist might say ...
The compatibilist has actually said 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. So, let's not go wandering all over the place with Trick Slattery.
Coercion is when someone imposes their choices upon us by force or the threat of force.
Undue influences include any other influences that can prevent us from making reasonable choices for ourselves. A significant mental illness or brain injury that imposes hallucinations or delusions upon us, or that impairs our ability to reason, or that subjects us to an irresistible impulse would be one example. Another example would be manipulation by hypnosis or through deception. Another example would the influences of unequal power such as between parent and child, commander and soldier, doctor and patient, etc.
The action was not willed, but necessitated by inputs acting upon neural networks and acquired proclivities.

The action of ordering each dinner was deliberately chosen by each customer. And what did they deliberately choose? They deliberately chose an "I
will have this for dinner" or an "I
will have that for dinner".
The
choosing causally necessitated the
will. The
will causally necessitated the dinner
order given to the waiter. It's quite simple
It is trivially true that 'you' made a decision (common language), but it is specifically true that it was a part of you, your brain, that responded to its inputs without 'you' being aware of the process until thoughts were brought to conscious attention.
Nope. You've over played your Libet. I was consciously aware that I was in a restaurant. I was consciously aware while browsing the menu. I was consciously aware that everyone else at the table had already given the waiter their order and they were all waiting on me to make up my mind. Your notion that I was unconscious through all these events is absurd.
There is an interaction of conscious and unconscious brain activity throughout this experience of deliberately choosing what I will do.
As to the timing of my conscious awareness of the choice itself, it was only required that it be in time to tell the waiter, "I will have the lobster dinner, please".
Oh, one more thing, it was not "trivial" that it was "I" that made the decision. After all, the waiter had to know who ordered which dinner and who should receive each bill.
...You change your mind because information has altered the state of the brain.
Right. For example, I may get home and find that the lobster disagreed with my tummy. That's
new information. I may find that I regret my choice, and I will think about what I could have done instead. For example, I could have had the steak, or, I could have had the fried chicken, etc.
Another key function of "could have" is examining our past choices. If the choice turned out badly, we want to learn from them. What could I have done differently? How would things have been different if I had chosen that other option instead?
You break these functions when you destroy the meaning of "could have". And worse, when you make us the victims of a slew of imaginary causal agents (determinism, causation, laws of nature, the past, information, etc.) that plot together to control our future, you make the future hopeless.
''To make a long story short, the brain state you have at any given moment is dictated by causal processes that are ultimately out of your control. "
What you and Trick Slattery fail to realize is that those brain states that deliberately choose what I will have for dinner happen to be "me" deliberately choosing what I will have for dinner.
You're creating an imaginary problem, just like Zeno does in his paradoxes. The false, but believable, suggestion that creates the paradox is that
my brain states do not include me. Thus you claim that I must somehow exist in a form that is separate from my brain and that I must control what my brain does. It sounds like we must exist as "souls", separate from our brains! So, is that what you're preaching?
The definition of free will (P1) does not require freedom from our brain processes.
We may say the light could have remained red, or could have cycled normally, could have failed entirely....or any of the possibilities that are associated with traffic lights due to their mechanisms and faults, but whatever we say is spoken from our ignorance of the state of the system, but whatever the light does in any given instance in time is determined by its information state in each and every instance in time....with no possible alternate action in any given instance.
The actions that the traffic lights perform proceed as determined. We in our ignorance can only guess based on statistics and our past experience with traffic lights.
The notion of "can happen" is exactly that, a matter of our uncertainty, our "ignorance" of what will actually happen. When we don't know what will happen, we imagine what can happen, to prepare for what does happen.
We slowed down, because the light could have remained red. And we say that with certainty even though we know for a fact that it did not remain red.
When deciding between the steak and the lobster, we begin in ignorance of what our choice will be. But we know with certainty that it can be the steak. And, we know with certainty that it can be the lobster. We are only uncertain about what it actually will be.
At the end of deciding, we know with certainty that it will be the lobster, and we know with certainty that it could have been the steak.
