If you substitute direct choice of a particular next state and instead are only allowed to sample a state space, you still aren't free to choose.
Said another way: flipping a coin cant't make Harvey Dent free.
While these values take a larger range, they are still limited. I believe the coin example jjaredsimpson gave was, while hyperbole, to show that the states are limited, and thus can't be used in and of itself as an explanation of free will.
I would agree, and it's a concise way of putting it. It's easy to criticize the idea of quantum consciousness since no one yet can understand or explain how it would be physically possible, but in a deep way the idea of brains "capturing" / amplifying indeterminacy is extremely attractive.
I read Penrose, etc, but at the end of it could not find any plausible mechanism for humans having free will in the sense of uncaused causation. But I use a modified version of Daniel Dennett's take on it: we CAN choose, we just can't choose what we choose.
Another way of looking at it is to have two different "modes" for thinking of free will: in everyone's daily lives, they use the "traditional" view (how else could we have such things as moral praise or blame?), but when you look at the human brain as a physical system, you use the deterministic/pseudodeterministic view.
However, there is the Strong Free Will Theorem of Conway and Kochen. Essentially, they prove that "if humans have free will, then elementary particles already have their own small share of this valuable commodity", see http://www.ams.org/notices/200902/rtx090200226p.pdf
I'll consider the realistic philosophical consequences of that seriously once they are presented. Your inability to imagine how someone can live with that doesn't provide any support for, and isn't an example of, what those realistic philosophical consequences are.
if there is no free will ... You might as well kill yourself now
So if one doesn't have choice, one should choose to kill oneself? This makes no sense.
Does that steak taste any worse? Does the sunset seem less beautiful? Do your decisions feel less real?
Enjoy the ride! You only have 1 ticket =)
If every particle in the human body could be acocunted for, and its next state predicted deterministically based on a fixed set of laws, that means no living organisms have free will, and are merely executing a program whose behavior and outcome is determined solely by its initial state. There is no "ongoing input" in the form of free will decisions/choices.
And you need to take the realistic philosophical consequences of that very seriously ... if there is no free will ... I simply cannot imagine how someone can live with that. You might as well kill yourself now, since you are nothing but a robot.
I really do despise (and am horrified) by a worldview that says we're all robots, and have no free will. Learning about indeterminacy at the quantum level was a huge relief. It's a logical deduction/conclusion that this low-level indeterminism is likely amplified into "choice" in human beings.
