With as many neurons and synapses as we have, there is more than enough complexity to expect the mind to be purely physical. I don't see why that bothers so many people; I think it's incredibly awesome.
Is it not possible that the brain simulates the experience of qualia (itself a philosophical zombie) but that this process is what causes the non-physical mind to exist, and to experience those qualia?
Wouldn't determinism have been "easier?" If there is no free will, non-determinism seems like a lot of trouble to go to for nothing!
>Wouldn't determinism have been "easier?"
This question doesn't really have any meaning. Easiness is a concept imagined by humans in the context of our own endeavours. And even if you suppose a sentient creator similar to ourselves, we still have no means to judge what kinds of universes would be easier or harder to create.
