well what I think it comes down to, is if anyone can know with 100% accuracy your actions before you make them, then we have no free will. and an omnicient anything would know with 100% accuracy, be it miss cleo, or God. but just as long as someone knows, we are just following the plan as to what he or she already knows.
I think the general problem in arguing that free will negates determinism in the world is that our conception of free will needs to be modified. Let's assume that the world is deterministic, forgetting about quantum mechanical arguments of uncertainty for the time being.
We can consider that beyond instincts we are born with, we go through our lives 'writing' to our memories the outcomes of our actions and whether those actions obtained a good or bad result. We find we like ice cream and we write that to our memory. We may not like our work necessarily but we write it in as necessity. We continue this way making continuous rankings. We would never go get ice cream instead of going to work. But we might find we can stop for ice cream assessing whether we will be late for work and if so, is it worth it. This goes on, so-on-and-so-forth ranking and comparing past outcomes and future possibilities.
Now there are two things I would suggest we establish:
1. We need to admit that we make these comparisons and decisions within a 'physical' mind that is subject to 'physically' delivering our decisions. That is we don't think that the entire process is based on processing the decision through a physical system, subject to classical laws and then somehow just before the decision (let's say up to the point the last electron is delivered into position) that there is a metaphysical and non-classical 'delivery' of the decision. To say otherwise is to suggest we would make a decision completely without reason; the outcomes would have nothing to do with what we are thinking. So we 'freely' made the decision, but it was subject to a lot of written data about what we think is good for us and what we think is bad. Were we forced to the decision? Yes, I think it must be completely deterministic, but this is precisely the way we like it, we are happy to have it forced into a direction that satisfies our sensibilities.
2. All our decisions are deterministic - Would you ever make a decision by letting your logic operate so that the outcome is not from a set of physical steps as described. That is comparing what is written in you memory? Actually, I would say no. We are incapable of delivering an answer that is not from 'physical' logic that is determined stepwise. That many outcomes were posssible before delivering the decision does not refute the determinism. Only one outcome was delivered, therefore it went down a determined path, regardless of perturbations along the way (they are actually part of the determinism). No matter how much we microscopically divide and look more closely at the physical processes, we never get to a point that something metaphysical occurs in the decision making. Anything that was part of the process, must have played out in the physical plane of reality, regardless of where it came from.
So is free will eliminated. No, it is just the way we like it. We are simply restricted from getting up in the morning and deciding we want to live on alpha-centauri today along with many other eliminated possibilities.
Free will is just as we like it, just not everyway we would have it: Don't we expect that all physical things will work deterministically and our mind is part of those 'physical things'?
- the Earth in its specific orbit about the sun gives us stable environment
- Our gas stove predictably burns propane to heat our food...we don't wake up and find laws governing controlled flammability of the propane have disappeared
- Our bodies including our heart and all vital organs work predictably and deterministically. We would not have it any other way.
Why then would we expect the determinism to be repealed with the processes working in our minds as we make decisions? To suggest it is not this way is to suggest there is a step that is metaphysical in our decision processes when in fact our free will is delivering an answer just the way we like it, physically deterministic. There is no other process that can play out in the physical plane.
This was the long way of saying, if God knows all your actions and they are predetermined, but you do not know them, you still have free will just the way you like it. You are happy that you are prevented from living your day on alpha-centauri, yet concerning all the other possible directions in your normal life that you have chosen, it's difficult to see that you are equally happy with the decisions you were prevented from making; it's why you made the decision that you did. Again, you have free will just as you like it, just not everyway you would have it.
