The fundamental point is that if determinism is true then morality is meaningless. I think we have free will.

(This will probably be a controversial point on HN so to expand a little: I think consciousness is both non-mystical and non-material - the mind is entirely natural, mind and matter interact, but the mind is not the same as the brain, and is not made of atoms. Qualia and the binding problem [1] cannot be explained in material terms. Furthermore, if our thoughts are merely deterministic neurons firing, then we don't have any reliable knowledge of reality, making any debate meaningless).
