There's no scientific understanding of where exactly consciousness is rooted, so if you take that to assume it means there's no such thing as conscious choice, I conclude you are a fatalistic downer who I don't want to hang with.
It has exactly as much basis as the alternatives, explains the world just as well, gives the exact same predictions, but needs less assumptions.
BTW - why is lack of free will a downer? I perceive is as neutral.
Not the GP, but lack of free will implies that people have no agency over their actions, and hence can't really take pride in anything they've accomplished. They're just squishy robots following their programming and lying to themselves about why they do the things they do.
Or at least that's one depressing way to interpret it.
Don't assume we have a free will when debating if we do :)
If we don't have a free will, then the fact that we believe in free will is irrelevant, and you cannot deduce that we believe in it from the fact that we act as if we believed in it.
Free will is most probably a quirk of language, an answer to a misleading question based on wrong assumptions. There are no difference in the state of universe no matter if there is free will or not.
