Do you believe in free will? (lemmy.world)

There is an argument that free will doesn't exist because there is an unbroken chain of causality we are riding on that dates back to the beginning of time. Meaning that every time you fart, scratch your nose, blink, or make lifechanging decisions there is a pre existing reason. These reasons might be anything from the sensory enviornment you were in the past minute, the hormone levels in your bloodstream at the time, hormones you were exposed to as a baby, or how you were parented growing up. No thought you have is really original and is more like a domino affect of neurons firing off in reaction to what you have experienced. What are your thoughts on this?

Ican't fathom how someone, even given a perfect model of every cell in my body, could predict whether or not I will scratch my nose within the next minute.

so your argument is just personal incredulity?

The issue is not about choice. It is about control. Your next action is purely dependant on the current state of your brain and the stimuli around you. Where is the part that isn't controlled by this system? How did you cause your brain to be exactly how it is right this moment? Was it not a cause of your previous brain state and the stimuli in the previous moment? How can you shown it's not turtles all the way down?

The chaos comment is not really relevant. Chaos isn't choice, I only brought it up to show that at the level of our brains and the interactions we have there isn't anything random. A world rewound would produce the same outcome.

I think you're missing my point: I opened by saying that I definitely believe the world is deterministic. I then went on to problematise the extremely unpredictable nature of the human mind. To the point where an immeasurable amount of historical input goes into determining what number I will say if you ask me to think of one.

Then, I used the argument of a chaotic system to reconcile the determinism of the universe with the apparent impossibility of predicting another persons next thought. A highly chaotic system can be deterministic but still remain functionally unpredictable.

Finally, I floated the idea that what we interpret as free will is in fact our mind justifying the outcome of a highly chaotic process after the fact. I seem to remember there was some research on split-brain patients regarding this.
