Then in the same sense in Platonia, future hazards are not inevitable, since
after all the Life game in which the hazard is or isn't avoided is a
Platonic object and its outcome is not changed by implementing it
More generally, I see Dennett's compatibilism as a sort of apology for
determinism, reframing "free will" so that we can tell ourselves we have it
even though the obvious conclusion is that it is just an illusion. In other
words, if in fact free will were just an illusion due to the fact that we
don't know what we're going to do until we do it, how would the universe, or
our experience of it, be any different? If the answer is "it wouldn't", then
what purpose is served by the concept of free will other than to make us
feel better? I am quite happy to drop not only free will but also ideas such
as absolute morality, a self persisting through time, and even a separate
physical universe if the only reason to hang on to them is an emotional one.
At the same time, I am quite happy to continue living my life as if all
these things are in fact real, and I think it is better to live an illusion
rather than a delusion.
