This is one of the biggest questions of human history. Whether we are responsable for our actions or we are just part of a complex system.
Personally, I think determinism is a more realistc approach to understand reality. Because I don’t see how humans are a separate thing from everything else.
We are just a result of everything that surrounds us, of all the external and internal proccesses that occur whether we like it or not. To think otherways seems to me like don’t wating to acknowledge all the discoveries the human race has collected thought the scientific method.
Sam Harris is a neuroscientist which once wrote: “You are not controlling the storm, and you are not lost in it. You are the storm.”
Simply put, we are as free as the wind is.
(If you know how the wind works, you’ll understand why this isn’t an argumnet in favour of free will).
There’s only one very big problem that concerns me about the deterministic way of acknowledging the wold, and that is, morality becomes absurd.
We are just a drop of water in an endless river, we can’t go against the current and we cannot pretend that we are not part of it.
