Regardless of if it’s practical to live that way in daily life, the world seems pretty determined. Everything happens because a vast amount of interactions between infinite factors causes it to. You can’t really say you choose between things as many influences have been taken in by you and many things have affected your psychological state. Has everything been practically decided by the big bang? Now, this is not to say we can know everything or predict the future, but we know what’s likely. Socialism or extinction may be inevitable, but we don’t know yet. Socialism can only happen if people keep fighting, regardless. People will be convinced or principled or not. Science seems to agree with this, and only few, like the wrong Sartre would propose we have ultimate free will. So are there any arguments against determinism? I know there is a saying that you’re freer when you recognize how your freedom is restricted, and that recognition may make your actions better, but isn’t there ultimately no freedom?
A sentient being “chooses” between given options, but that choice is not “free.” One chooses oats or toast because they are prefer it at that moment for a variety of factors. It could take less work, it could taste better due to how their taste buds work or whatever, it could be cheaper. I mentioned your marxist take in my post. I think it’s strange to start with the assumption that it does exist somehow.
