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?
The circumstances that led you to any particular decision are pre-determined at the time you’re making that decision, simply through the fact that those circumstances have already happened prior to the current decision at hand; but that doesn’t mean you don’t have the free will to make that decision in the moment.
To extend on that a little: if you were able to make the same person face the same decision multiple times under identical circumstances, I don’t believe you’d get identical results every time. It may not be an even distribution between the possible choices; but it wouldn’t be a consistent answer either. The Human element introduces too much chaos for that kind of uniformity.
