Determinism includes everything within the system.
That's what I've been saying, over and over! Determinism cannot exclude any event. It cannot exclude choosing any more than it can exclude a tree growing or the rain falling or anything else that happens. We cannot pretend that trees don't grow or that people don't chop them down to build houses. We cannot pretend that rain doesn't fall or that people don't invent umbrellas to stay dry.
And most important, we cannot pretend that the people in the restaurant are not choosing what they will have for dinner, while free of coercion and undue influence.
The brain, according to the definition, is subject to determinism.
Using the wrong metaphors can distort the truth. The brain is not "subject to determinism". The brain simply "functions deterministically". Everything that happens within our brain, every neuron firing, every thought and feeling we experience, is reliably caused by prior neurons firing, and prior thoughts and feelings.
The proper metaphor is not determinism being the "king" of the brain, but rather the brain itself being determinism exercising control over other objects. For example, I filled a cup with water to take my morning pills. My brain controlled these events, and it did so deterministically.
My brain is simply doing what it naturally does. Neither the laws of nature nor determinism are external "agents" controlling what I do. They are simply me, doing what I naturally do.
Complexity doesn't give a brain exemption.
Don't worry. I've never suggested that complexity itself provides agency. Scrambling eggs introduces complexity without improving function.
It is simply that the brain has evolved into a machine that can perform rational thought, which enables it to perform logical operations like choosing, or arithmetic, or planning, or any of the other many functions that it performs. It is simply by the nature of its structure that it is able to do these things. Just like it is a matter of structure that a microwave oven is able to cook our breakfast and an automobile is able to transport us to work.
There are no two or more options to choose from in any given instance, consequently, no choice.
Choosing is a logical operation, like addition. Both operations actually happen in physical reality. Determinism does not eliminate any choosing events any more than it eliminates any addition events. We perform addition whenever we need to find the sum of two or more numbers. We perform choosing whenever we need to decide between two or more options.
In the restaurant we must choose from a menu of options to determine what we will order for dinner. And the waiter must add the cost of our food with the cost of our drinks to determine our bill. We cannot say that the addition is happening but the choosing is not happening. Both the choosing and the adding were equally causally necessary from any prior point in time.
Every action, including brain activity, is necessitated by antecedents, inputs, neural architecture, information processing, and so on.
Correct. All mental events, whether choosing or adding, are necessitated by antecedent events and inputs, neural architecture, information processing, and so on. Both choosing and addition are forms of "information processing".
Living organisms exhibit
purposeful behavior. While still
affected by gravity, they are
governed by biological drives to survive, thrive, and reproduce. Place a squirrel on that same slope and he may go up, down, or any other direction where he hopes to find his next acorn. His body is able to marshal energy to resist the pull of gravity as he scurries up a tree.
Intelligent species exhibit
deliberate behavior. They come with a brain capable of imagining, evaluating, and choosing. While still
affected by gravity and biological drives, its behavior is
governed by deliberate choice. It can choose when, where, and how it will go about satisfying those drives.
Purposeful behaviour is not an exemption from determinism, nor is intelligence or deliberate behaviour.
There is never any requirement for any exemption from determinism in order to decide for ourselves what we will do while free of coercion and undue influence. Free will requires no exemption from determinism whatsoever.
Deliberation is a brain process: information is acquired and processed according to the information state, neural networks/memory function, etc, of the brain, which in turn produces output in the form of thoughts, feelings and actions.
Yes. We know all that. There is no dispute about the facts of neuroscience, except your own dispute with the neuroscience claim that the brain actually does make decisions and therefore choosing really happens in the real world.
An inevitable progression of events does not permit choice. I'll have 'this' instead of 'that' if 'that' is determined cannot happen.
An inevitable progression of events not only DOES PERMIT choice, it damn well REQUIRES choice to happen whenever it happens!
And that logically results in "I
would only have chosen the Chef Salad for dinner that night, even though I
could have chosen the Steak instead".
What Does Deterministic System Mean?
''A deterministic system is a system in which a given initial state or condition will always produce the same results. There is no randomness or variation in the ways that inputs get delivered as outputs.''
That's determinism.
Indeed it is. Given the same person, exactly as they were at the time they made that choice, with exactly the same prior experiences (the bacon and eggs for breakfast and the double cheeseburger for lunch) and exactly the same goals and reasons (the doctor's advice to eat more fruits and vegetables), they always
would have ordered the Chef Salad, even though they
could have chosen the juicy Steak. And
both the "would have"
and the "could have" would be causally necessary/inevitable from any prior point in time.
