My point is simple. Causal necessity does not change anything in any meaningful or relevant way. All events are always the result of prior causes. And this happens to include the "free will" event. Free will is an event in which a person decides for themselves what they will do, while free of coercion and undue influence.
If will is fixed by prior causes, it cannot be defined as a free will event.
But you've seen me do exactly that, simply by using the ordinary, common sense definition of free will: a choice we make for ourselves while free of coercion and undue influence. This is the free will that is used when assessing a person's moral or legal responsibility for their actions. It is the only rational definition of free will.
The definition you're using is the nonsensical "freedom from causal necessity". There is no freedom from reliable cause and effect, because every freedom we have, to do anything at all, requires reliable cause and effect. Thus "freedom from causal necessity" is an oxymoron, a self-contradiction, presenting us with the paradoxical question: "How can we be free of that which freedom itself requires?"
It's just another determined event, ...
Choosing the salad was indeed just another determined event. It was causally necessary, from any prior point in time t, that I would be making that choice, for my own reasons, while free of coercion and undue influence, and thus "of my own free will".
The salad was chosen, so "not chosen" is empirically false.
The menu of alternate possibilities required me to make a choice. So, I willingly considered my options and chose the salad. So, "not willed" is also empirically false.
And the action that necessarily followed my choosing the salad was to communicate this intent to the waiter, "I will have the Chef Salad, please".
All of these claims have been refuted repeatedly by the empirical evidence.
Information interacts with neural networks, information exchange, and an action is initiated and reported in conscious form, in that order of events.
You are simply choosing another way to describe the exact same event in order to hide the facts. For example, it was a fact that I considered the juicy steak for dinner. And it was a fact that my goal of eating more vegetables brought to my awareness that I had already had bacon and eggs for breakfast and a double cheeseburger for lunch. And it was also a fact that I then turned my conscious attention to the Chef Salad, and then chose to order the salad instead of the steak. Finally, I told the waiter, "I will have the Chef Salad, please".
This event is commonly known as "a choice of my own free will". And, of course, it also involved my own physical neural network processing information and involving conscious awareness at key points in the process.
Free will is being asserted, not demonstrated.
Meaningful free will is clearly demonstrated in every restaurant, every day. This is an indisputable fact. So, the claim that free will is not being demonstrated is false.
Asserted in the face of evidence to the contrary, a system that entails all actions, where nothing is freely willed.
Universal causal necessity does not contradict the meaningful definition of free will. It simply means that all free will events are inevitable, just like all coercion events are inevitable, just like all events involving undue influence are inevitable. There is nothing in a world of perfectly reliable cause and effect that happens outside of perfectly reliable causation.
Therefore, the claim that a perfectly deterministic system that entails all actions is "evidence to the contrary", is clearly false. Rather it is evidence that free will events are just as inevitable as all other events.
All causally necessary events actually happen in physical reality. Even mental events correspond to physical brain processes which are happening in physical reality. So, when choosing happens, it is really happening, as a physical event within a physical brain.
The brain organizes sensory data into a symbolic model of reality. It represents this reality with language and sensory images. With this model, it imagines possible futures (what I can do and what can happen) and possible pasts (what I could have done and what could have happened). It forms plans and sets its intent upon doing specific things (what I will do), either right now (I will have the Chef Salad for dinner) or in the future (my "last will and testament").
Evolved mechanisms that enable the ability to acquire and process information and respond in complex but deterministic ways, each and every increment of information interaction, however complex, being fixed by the prior state of the system, inputs, processing, memory function, output.
Yes. However, we've also learned that irrational beliefs can lead to false conclusions, which result in harmful actions. The belief that universal causal necessity absolves us of all responsibility for our actions, is one of those false beliefs. And it can have harmful effects, as summarized by Eddy Nahmias in
Why ‘Willusionism’ Leads to ‘Bad Results’: Comments on Baumeister, Crescioni, and Alquist :
"When interpreted in ways that the evidence does not justify, the willusionist claim can lead to ‘bad results.’ That is, telling people that free will is an illusion leads people to cheat more, help less, and behave more aggressively"
