There we go again. None of your statement makes the least bit of sense if the universe is truly determinant. I am not picking on you in particular. Even the people that claim they believe in determinism in this thread have made statements that contradict that. You are assuming there is a ‘You’ that can make a choice. There may very well be but not in a truly deterministic universe.
My personal position is that I am the ultimate agnostic and I not only don’t know the full reality, I am incapable of it. I am not a big fan of determinism arguments because they depend on a full understanding of consciousness and nobody in the world is any closer to understanding that than they were 500 or even 100,000 years ago. Even the best neuroscientists or computer scientists in the world today cannot explain what it is or why it happens.
Don’t listen to anyone that claims to know how any of this works because they don’t.
To me, that is key. If the best scientists in the world cannot explain it, then it is all masturbatory intellectual speculation from everyone else. For all we know, there could be a breakthrough for the understanding of consciousness like relativity that makes everything a little more clear but then goes dark again when you get into the realm of something like quantum mechanics.
People today are not as nearly as smart as we choose to think. There are reputable scientists that believe we are living in a simulation, others that think there are multi-verses in which every possible outcome happens and real mathematical evidence that time does not exist the way we perceive it. No amount of Mary Jane or shrooms can sort sort out those ideas because no one has any solid theoretical framework about how it works.
There are at least two known miracles in the universe. One is creation. Science has given up for explaining that for now. The other is consciousness. We have made almost zero progress in understanding it despite decades of research. Once some unified theory of those is worked out, especially the latter, then we can talk we can talk about causality. However, right now, there are many plausible answers and some of them are more bizarre than finding out that time runs at different rates depending on speed and particles can be in more than one place at a time (all provable results).
