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.
In a determined world, the possibility of doing otherwise is an illusion.
A "possibility" exists solely within the imagination. We cannot drive a car across the possibility of a bridge. We can only drive across an actual bridge.
But a possibility is not an illusion, because we cannot build an actual bridge without first imagining a possible bridge. The notion of a possibility serves an essential mental function, enabling us to plan our deliberate actions to accomplish some deliberate intent. The thought of a possibility has empirical functionality, that is, it causes things to happen in the real world.
The thought of a possibility is an empirical event, and just like every other event, it is causally necessary from any prior point in time.
If determinism allows any action to be taken, it's not determinism. The word 'determined' means final. Final as in fixed. Finalized or fixed by prior states of the world.
Imagining building a bridge doesn't appear in a vacuum. Conditions in the world in relation to human needs, wants and engineering skills brings forth the idea of building a bridge, and if the need is strong enough, the impetus to put imagination into action.
Countless elements and events went into imagining building a bridge and carrying it out.
Each and every diner is restricted to the option that was determined.
Each and every diner will necessarily consider multiple possibilities from the menu as they decide for themselves what they will order for dinner. The multiple possibilities are just as inevitable as the single option that was finally chosen.
Determinism changes nothing. Everything happens in precisely the same way.
The brain of each and every diner acquires information from the menu, which is processed (brain state, proclivities, etc), conscious deliberation generated and related action initiated, you choose Lobster on that occasion. The only possible result on that occasion.
Information processing, not free will.
''If Determinism is true, human beings lack the ability to think in a manner that is not 100% caused by prior activity that is outside of their control, and thereby lack Free Will. By the same token, if human beings have Free-Will, they are capable of thinking in a manner that is not 100% caused by prior activity that is outside of their control, which rules out Determinism." ,,, - Bruce Silverstein, B.A. Philosophy
Nope. If you start out with false assumptions you will end with false conclusions, as Mr. Silverstein does. The assumption that our thoughts are 100% caused by things that are not our thoughts is false. Thinking, like walking, is something we do. It is not done for us by some external entity. It is actually us doing the walking. It is actually us doing the thinking.
It's a brief summary with a bit rhetoric thrown in, but essentially sound.
Sensory information acts upon the system. As described in prior posts, the brain has evolved to acquire information from the environment and respond to it in adaptive ways (if functional)
We respond to objects and events in the external world, which our brain represents in conscious form. We don't choose our genetic makeup or neural architecture, how our brain functions or responds.
The illusion of conscious control is revealed when things go wrong with the system.
This is a simple empirical observation that cannot be dismissed by metaphysical abstractions.
Given a determined world, the 'choice' you made was determined before you entered the room.
The choice was determined by the choosing. The choosing did not occur until I entered the restaurant, sat at the table, and scanned the menu to see what possibilities were available. Determinism does not mean that any events happen before they happen.
The choice was determined by the interaction of information within the system prior to conscious awareness, narrator function, etc...
As you said yourself;
''Determinism means that events will proceed naturally (as if "fixed as a matter of natural law") and reliably ("without deviation").
''All of these events, including my choices, were causally necessary from any prior point in time. And they all proceeded without deviation from the Big Bang to this moment.'' - Marvin Edwards Post #887
Yes, but the Big Bang happened when it happened, and not a moment before. And my choosing happened when it happened, and not a moment before.
Yes, events unfolding as determined, state by state, in each and every moment in time with 'the way things going thereafter fixed as a matter of natural law.'
The illusion you're experiencing is another result of figurative speaking. Because my choice was inevitable, it is AS IF it had been already made at the time of the Big Bang. But all figurative statements are literally false. Empirically and objectively, the choice was made by me in the restaurant. The Big Bang played no meaningful role in my decision. That's why the waiter brought me the bill, rather than bringing the bill to the Big Bang.
You don't exist in isolation. The world brought you forth. The world acts upon you, and you respond according to the state and condition of the brain that processes the information it acquires and responds to.
But you were not free to choose.
And yet I did choose. So, you are mistaken. In fact, deterministically speaking, it was causally necessary that I, and no one else, would be doing the choosing.
Choice entails the possibility of an alternative. Necessitation ensures that that no alternative is possible.
Repeatedly wrong. Causal necessitation ensured that there would be a menu of alternatives that I would choose from!
There is a menu. The menu has a range of options. Given determinism, the option you take on this occasion is the only possible action. Determinism doesn't allow alternate actions in any instance in time, only what is determined by the state of the system in any given instance in time.
It is not you who choice, but the system, the world, that brings you to that location and precisely that action in relation to that menu.
All of these events, including the menu of alternate possibilities, were causally necessary from any prior point in time. And they all proceeded without deviation from the Big Bang to this moment.
The menu has a list of options, but each diner has only one possible action in any moment in time.
''In
neuroscientific circles, ... "Even though there’s no one in charge of its operations, the brain generates a strong intuition of personal agency, borne out by the obvious fact that persons accomplish all sorts of things in all manner of ways.''
No surprises here either. The last sentence though is the key. The brain's sense of self is "borne out by the obvious fact that persons accomplish all sorts of things in all manner of ways." Our sense of self simply comes from empirically observing ourselves choosing to do all sorts of things, like ordering a dinner from the restaurant menu.
We see ourselves doing it, and oddly enough, we conclude that we did it.
But conscious self is not doing it. The distinction being that conscious self in not in control, that it's specifically the brain that is generating the experience of self-awareness and conscious control, an illusion that is exposed whenever things go wrong with the brain.
We as conscious people have no access to the means of our experience.
Tenet: Consciousness is associated with only a subset of nervous function
''Based on developments of the past four decades, there is a growing
subset consensus – that consciousness is associated with only a subset of all of the processes and regions of the nervous system''
''Consistent with the subset consensus, many aspects of nervous function are unconscious.
Footnote 3 Complex processes of an unconscious nature can be found at all stages of processing (Velmans
Reference Velmans1991), including low-level perceptual analysis (e.g., motion detection, color detection, auditory analysis; Zeki & Bartels
Reference Zeki and Bartels1999), semantic-conceptual processing (Harley
Reference Harley1993; Lucas
Reference Lucas2000), and motor programming (discussed in sect. 3.1). Evidence for the complexity of unconscious processing is found in cases in which the entire stimulus-response arc is mediated unconsciously, as in the case of unconsciously mediated actions (e.g., automatisms).
There is a plethora of evidence that action plans can be activated, selected, and even expressed unconsciously.
Footnote 4 In summary, it seems that much in the nervous system is achieved unconsciously. This insight from the subset consensus leads one to the following question: What does consciousness contribute to nervous function?''
''Regarding the skeletomotor output system, one must consider that all processes trying to influence skeletomotor behavior must, in a sense, “go through it.” Each system giving rise to inclinations has its peculiar operating principles and phylogenetic origins (Allman
Reference Allman2000): One system “protests” an exploratory act while another system reinforces that act (Morsella
Reference Morsella2005). Because each skeletomotor effector can usually perform only one act at a time (e.g., one can utter only one word at a time; Lashley
Reference Lashley and Jeffress1951; Wundt 1900), there must be a way in which the inclinations from the many heterogeneous systems can be “understood” and processed collectively by the skeletomotor output system. To yield adaptive action, this process must also integrate information about other things (e.g., the physical environment).''
