The compatibilist proposition is simply that free will is a meaningful concept within a deterministic world.
The
proof is this:
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.
The compatibilist definition is inadequate because unimpeded actions necessarily follow from necessitated decisions.
I've just demonstrated a proof of compatibility and you have not questioned any of the premises, so I believe you are stuck with the conclusion: The notion of a freely chosen will (and its opposite) is still meaningful within a fully deterministic world.
Freedom demands causal power in agents, the ability to regulate decision making and access or initiate alternate action, to have done otherwise;
And the agent, when sitting in the restaurant and reading the menu, has the power to choose any item on the menu. If you wish to empirically test for this power, then order the first item on the menu today. Come again tomorrow and order the second item from the menu. Continue this testing until you've ordered each item on the menu.
Your power to order any item off of the menu can be empirically demonstrated, very easily.
Perhaps you had some other notion of power? Perhaps you were thinking that one must be able to choose to become someone else? Or, perhaps you were thinking one must be free of prior causes in order to be the meaningful and relevant cause of their own actions? Those are kind of silly, don't you agree?
Necessity;
If one’s solution to the free will problem is in terms of real causal powers of agents then one ought to be an incompatibilist. Some premises are contentious but the following new argument for incompatibilism is advanced:
1. If causal determinism is true, all events are necessitated
2. If all events are necessitated, then there are no powers
3. Free will consists in the exercise of an agent’s powers
Therefore, if causal determinism is true, there is no free will; which is to say that free will is incompatible with determinism, so compatibilism is false
Well, don't depend upon what others have come up with unless you're ready to defend it. Going by the abstract, the authors of that article have seriously blundered. Here's why:
Premise #2, "If all events are necessitated, then there are no powers", is not only false, but is clearly paradoxical. If there are no powers, then how is any event ever necessitated? Force, such as the force of gravity, causally necessitates the orbit of the Earth around the Sun. Without that force, the Earth would fly off into space. So, gravity has the power to keep the Earth orbiting the Sun. Gravity exercises this power without choosing to do so, so gravity has no free will. But it definitely has the power to necessitate planetary orbits and necessitate objects falling to the ground when dropped, etc.
Premise #1 is correct, a priori, by definition. Determinism is the belief that all events are necessitated by prior events.
Premise #3 is almost correct, but it only applies to the agent's specific power to choose for themselves what they will do.
Because premises #1 and #3 do not contradict each other, we must conclude that compatibilism is true.
About freedom:
To have any meaning at all, a "freedom" must reference, either explicitly or implicitly, some meaningful and relevant constraint. A
meaningful constraint prevents us from doing something that we want to do. A
relevant constraint is something that we can actually be "free from" or "free of".
For example:
1. We set the bird free (from its cage).
2. We enjoy freedom of speech (free from political censorship).
3. We were offered free samples (free of charge).
4. We participated in Libet's experiment of our own free will (free of coercion and undue influence).
... Actions that follow from necessitated decisions are not free will actions, they are necessitated actions.
Case A: If my own goals, my own reasons, and my own interests causally necessitated my choice, then I was free to choose for myself what I would do. This is referred to as a freely chosen will, or simply free will.
Case B: If a guy was holding a gun to my head, and it was his goals, his reasons, and his interests that causally necessitated my choice, then I was not free to choose for myself what I would do.
Both are examples of causally necessitated actions. In Case A, it was causally necessary that I was free to choose for myself. In Case B, I was forced to submit my will to his.
Causal necessity holds true in both cases. Free will holds true in Case A, where I was free to choose for myself what I would do. But coercion, and not free will, holds true in Case B.
The fact of causal necessity
does not contradict the fact of free will in Case A, nor does it contradict the fact of coercion in Case B.
Definitions alone do not prove the proposition.
Well, that's why I presented you with a formal proof again at the top of this comment.
To claim that necessitated action, which are necessarily unimpeded or unrestricted by the very token of being determined is false labelling.
As to whether the
labelling is true or false will depend entirely upon the definition:
Free will is a choice we make for ourselves while free of coercion and other forms of undue influence.
Determinism is the belief that all events are causally necessitated by prior events.
There is no contradiction at all between these two definitions.
If you are unhappy with these definitions, then present an argument for some other definition.
It's simply that actions inevitably following antecedents makes freedom of will incompatible with determinism. In other words. ''determinism makes it impossible for us to “cause and control our actions in the right kind of way.”
Apparently, that claim of incompatibility is false. The fact that our choice is inevitable entails that it was also inevitable that we, and no other object in the physical universe, would be doing the choosing. We remain the most meaningful and relevant cause that necessitated that choice, when free of coercion and other forms of undue influence.
