Ryan, I found an article by a theoretical physicist which gives a brief but good outline of the problem with free will in relation to physics, I hope this link helps.
The article lists 10 misconceptions in regard to the subject of free will.
As a sample;
Fact 2: All known fundamental laws of nature are either deterministic or random. To our best present knowledge, the universe evolves in a mixture of both, but just exactly how that mixture looks like will not be relevant in the following.
Having said that, I need to explain just exactly what I mean by the absence of free will:
a) If your future decisions are determined by the past, you do not have free will.
b) If your future decisions are random, meaning nothing can influence them, you do not have free will.
c) If your decisions are any mixture of a) and b) you do not have free will either.
1. If you do not have free will you cannot or do not have to make decisions.
Regardless of whether you have free will or not, your brain performs evaluations and produces results and that’s what it means to make a decision. You cannot not make decisions. Just because your thought process is deterministic doesn’t mean the process doesn’t have to be executed in real time. The same is true if it has a random component.
This misconception stems from a split-personality perspective: People picture themselves as trying to make a decision but being hindered by some evil free-will-defying law of nature. That is nonsense of course. You are whatever brain process works with whatever input you receive. If you don’t have free will, you’ve never had free will and so far you’ve lived just fine. You can continue to think the same way you’ve always thought. You’ll do that anyway.
I am a reductionist at heart, so I am happy that I am on the same page as the author for "Fact 1".
Do you understand what the author meant by, "Just because your thought process is deterministic doesn’t mean the process doesn’t have to be executed in real time."?
In 4. the author says, "Besides, as I explained above, these processes might have a random component that is even in principle not predictable. It is presently not very well understood just exactly how relevant such a random component might be."; this is my argument.
But then the author says, "but neither do you have free will because nothing can influence this randomness.". My argument is that we are the randomness. We are the ones making these random decisions, but from an outsider's point of view, it's random.
You can choose between y1 and y2. y2 might be more beneficial, but maybe y1 is more ethical. The choice is ours to make.
The point is; randomness is not a choice, nor does randomness aid the decision making process (which requires coherent information and not random events), it being the ability to make decisions that is commonly though of as being 'free will'
So if random quantum fluctuations act upon the brain and cause changes in behaviour, it is not a choice the brain made by processing information relating to its own information base, memory, and a given set of options ....it's only an unchosen wild card thrown into the system that alters the course of neural activity in an unchosen and unpredicable way.
The distance over which quantum affects are dominant is called the Compton length. For a given mass, anything smaller than its Compton length is strongly quantum, and weak or even undetectable above...
Hence random quantum changes to the brain are not an instance of 'free will' and cannot support an argument for the presence of something called 'free will' with the system.
