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.
''Reliably caused'' appears to be a softer way of saying ''fixed.''
The problem with the terms "determined" and "fixed" is that they imply that causation is
finished. It gives the impression that everything has already happened (similar to Einstein's
Block Universe) . This gives the false impression that there is
nothing we can do about anything since it is as if it had "already happened".
The empirical truth is that things are not "fixed", because events continue to happen, forever. And, no event will ever happen until its final prior causes have played themselves out. This understanding reminds us that our choices and our actions still play a significant role in how things will eventually turn out.
When I choose to order the lobster for dinner, I am the most meaningful and relevant cause of that event. The Big Bang is
never the meaningful or relevant cause of any human event.
In fact, within the domain of human influence (things we can choose to do), the single inevitable future will be chosen by us from among the many possible futures that we will imagine.
While there will be only a single actual future, many possible futures will occur to us via our imagination, one of those functions of the brain.
If alternate actions are possible, events are neither 'reliably caused' or 'fixed' - and we are not talking about determinism.
That's incorrect. Alternate actions are considered "possible" if we are physically able to carry them out.
We never need to actually carry out those alternate actions in order for them to be "possible". If we
never perform those actions we
never call them "impossible", they simply are referred to as things we
could have done, but which we
did not do.
So, hard determinists are making errors in the logic of language. Errors in the logic lead to incorrect conclusions and false beliefs.
Maybe 'reliably caused' tacitly means 'Libertarian Free Will?'
Only if Libertarian free will is deterministic. But that's not something I wish to deal with here. One incompatibilist at a time, please.
Determinism means that events will proceed naturally (as if "fixed as a matter of natural law") and reliably ("without deviation").
However, in order for determinism to be true, it must include all events. For example, determinism cannot exclude the effects of natural forces, like volcanoes and tidal waves or a meteor hitting the Earth. Determinism cannot exclude the effects of biological organisms that transform their environments, like tree seedlings changing bare land into a forest. Determinism cannot exclude the effects of deliberate choices, like when the chef prepares me the salad that I chose for lunch.
Exactly. All events are included, which means that every signal sent between neurons is determined, with no alternate action possible.
The notion of possibilities is irrelevant to individual neurons. But the notion of possibilities is essential to the brain itself as it performs its decision making function. Without alternate possibilities the brain cannot make a decision. The menu in the restaurant is a list of alternate possibilities. The brain must narrow this list down to a single option, in order to tell the waiter what dinner to bring. If it fails to choose, it will fail to eat.
All the neurons involved in the choosing operation are being driven by the brain's need to order a dinner, AND, the experience of this need itself is a deterministic event that was causally necessary from any prior point in time. When you can realize that both of those statements are true, you'll understand compatibilism.
Different functional areas of the brain are interacting in a reliable fashion with each other, performing the choosing and placing the order for dinner. And all of these events were causally necessary from any prior point in eternity.
Which clearly excludes any notion of free will.
Quite the opposite. The choice need only be free of coercion and undue influence to include the notion of free will. There is no requirement that the choice be free from causal necessity.
If you wish to argue that there is some reason why the choice must be free of causal necessity, please do so. But causal necessity means that it was inevitable that I would be making this choice for myself while free of coercion and undue influence. So, my view is that causal necessity insures that the choice would be of my own free will.
As I said, it is function rather than will that determines behaviour.
The function of choosing is what determines the will that determines the deliberate behavior. The brain performs this function.
Rather than 'free will, it would make more sense to call it a 'free function.'
Which raises the question, "Free from what?". Is the function of choosing free from coercion and undue influence? Then it is a freely chosen will. The function does not need to be free of the brain in order to be free will. The function does not need to be free from causal necessity or prior causes in order to be free will.
Free will only requires that the choice be free from coercion and other forms of undue influence.
Possible lunches exist for different people.
It's the same menu. We all have exactly the same possibilities for lunch.
Only one lunch is realizable for any given person in any given moment in time.
All of the items on the menu are equally realizable. But only one lunch per person will be realized. The word "realizable" contains the notion of "ability" and "possibility". Realizable is something that "can" happen. The word "realized" refers to something that "did" happen. The fact that only one meal each was realized does not logically imply that any of the other options were "unrealizable".
If it is determined that you have Lobster for lunch (brain/environment interactions), there is no possibility of you having anything but Lobster for lunch.
If you look under the hood, you will find every possibility on the menu within the "brain/environment interactions". The fact that it was inevitable that I would order the lobster does not change any of those possibilities into impossibilities. It only makes them possibilities that I did not choose to order.
Nice article. But nothing to change the fact that our brains actually do the choosing, which is what I've been saying all along. As I've said before, I have no problem with any of the facts uncovered by neuroscience.
Your makeup and past makes you what you are, which in turn determines your actions.
Yes, which means it is really me that is choosing what I do. That genetic makeup and those past experiences exist solely within me, and whatever it is you think
they are doing,
I am doing.
''
Our brain is not a unified structure; instead it is composed of several modules that work out their computations separately, in what are called neural networks. These networks can carry out activities largely on their own. The visual network, for example, responds to visual stimulation and is also active during visual imagery—that is, seeing something with your mind’s eye; the motor network can produce movement and is active during imagined movements. Yet even though our brain carries out all these functions in a modular system, we do not feel like a million little robots carrying out their disjointed activities. We feel like one, coherent self with intentions and reasons for what we feel are our unified actions.''
Cool! Give it up for my guy Gazzaniga. But you only quoted the part that leaves us with the question. The part that provides the answer to that question comes later, here:
Michael Gazzaniga: The Ethical Brain said:
"Our best candidate for this brain area is the “left-hemisphere interpreter.” Beyond the finding, described in the last chapter, that the left hemisphere makes strange input logical, it includes a special region that interprets the inputs we receive every moment and weaves them into stories to form the ongoing narrative of our self-image and our beliefs."
When the "interpreter" has accurate information, then it can provide an accurate description of what is happening and why. But when its information is inaccurate or incomplete, it will still attempt to explain things using confabulation to fill in the blanks. For example, if a hypnotist gives you a post-hypnotic suggestion that when you hear the word "elephant" you will take off your shoes, and then wakes you and triggers you to take off your shoes, you will come up with a story to explain why you did so.
He goes on to show how people use this feature to accommodate ideas that may at first conflict with their religious beliefs. Nice article, worth the read.
