There is no valid argument that free will, as a choice free of coercion and undue influence, is inconsistent with a world of perfectly reliable cause and effect. We empirically observe reliable causation in everything we think and do. We empirically observe people deciding for themselves what they will do. Neither observation can be denied. Therefore they must be compatible.
A choice made without coercion or undue influence is still subject to inner necessity, unconscious processes and determinants that are not subject to will, wish, or regulation in the sense that something else can happen.
Obviously, free will is not "freedom from oneself" (inner necessity).
Obviously, free will is not "freedom from one's own brain" (unconscious processes and determinants).
Obviously, free will is not "freedom from causal necessity" (freedom from cause and effect).
Free will is simply a choice we make while free of coercion and undue influence. Nothing more. Nothing less.
The choosing operation will always have at least two options, such as A and B, which are possible to choose. "I can choose A" will be true and "I can choose B" will also be true. Both "can" happen, even if only one of them "will" happen. Therefore, regardless of what does happen, there will always be something else that "could have" happened.
There is a critical difference between saying that something "can" happen versus saying that something "will" happen. Many things "can" happen, even if only one thing "will" happen. So, it is always the case that "something else could have happened" despite the fact that "nothing else would have happened".
Thus, the argument you just stated is not valid in any of its claims.
Will plays no part in information processing, information processing determines response, therefore will cannot be defined as being free....
A person's will is the intention that is currently motivating and directing their thoughts and actions. For example, it is my intention to respond to these odd claims. Thus, my thinking and my typing are engaged in carrying out that intent. That is my will at this moment. I have decided that "I
will do this now".
Free will is not some entity floating around willy-nilly. It is a specific chosen direction for our efforts: Such as my efforts to "process the information" you have provided in order to provide better "information for you to process".
and the compatibilist definition fails to prove its proposition.
The compatibilist proposition is simple. Free will, as a choice we make for ourselves while free of coercion and undue influence, is still a useful and necessary distinction, even in a world of perfectly reliable cause and effect (deterministic causal necessity).
The proof of free will is all around us, as people go about their day making choices for themselves. For example, the diners in the restaurant will choose from the menu what they will order for dinner, while free of coercion and undue influence, and they are held responsible for their deliberate dinner orders by paying for the dinner they ordered.
Compatibilism habitually ignores that it is inner necessity - the state of neural networks in any given instance - rather than free will that is the agency of response.
We're not ignoring inner necessity. We simply do not require that our choices must be free of our own brains in order to qualify as free will.
Free will is a choice we make while free of coercion and undue influence. Nothing more. Nothing less. We fully expect this choice to be made by our own brain, operating deterministically, as brains normally do.
''An
action’s production by a deterministic process, even when the agent satisfies the conditions on moral responsibility specified by compatibilists, presents no less of a challenge to basic-desert responsibility than does deterministic manipulation by other agents.''
The bank teller is not held responsible for turning over the bank's money to the robber, who is pointing a gun at her head. She is not acting of her own free will, but is instead being coerced. The robber, having decided to rob the bank of his own free will, is held responsible for his actions.
As you can see, the compatibilist definition of free will, as a choice we make for ourselves while free of coercion and undue influence, is precisely the definition used when assessing a person's moral or legal responsibility for their actions.
The incompatibilist's definition of free will, as a choice we make while free of cause and effect, and free of our own brains, and free of our own genetic dispositions (nature), and free of our own prior lives (nurture), is NEVER USED to assess anyone's responsibility for their actions, because such freedoms are impossible. Compatibilist free will does not require any irrational/impossible freedoms.
Thus, the claim regarding responsibility has no merit (nor any sense) at all.
What you do want to do is determined by prior causes:
''Wanting to do X is fully determined by these prior causes. Now that the desire to do X is being felt, there are no other constraints that keep the person from doing what he wants, namely X.''
Compatibilist free will does not require freedom from prior causes. It only requires freedom from coercion and undue influence, nothing more and nothing less.
To suggest that free will and responsibility require freedom from cause and effect is simply irrational.
”If the neurobiology level is causally sufficient to determine your behavior, then the fact that you had the experience of freedom at the higher level is really irrelevant.” - John Searle.
Compatibilist free will does not require freedom from one's own neurobiology. It only requires freedom from coercion and undue influence, nothing more and nothing less.
To suggest that free will and responsibility require freedom from our own brain is irrational.
So, I would suggest that the incompatibilists stop making irrational demands upon free will, and accept instead the compatibilist definition, "a choice we make for ourselves while free of coercion and other forms of undue influence", which is consistent with both deterministic causation and neuroscience.
