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?
Yes I do, because my own experience of existence suggests I have it. Could that all be an illusion? Sure. But believing I don’t have free will would pretty much deny the existence of my self, which, being myself, I’m not really capable of, nor would I want to do that.
You could define self differently. Buddhism has some fun takes on it.
