How could the processes be detached from the materials, if their 'unfolding' is determined[1] by their physical properties? And how would those processes manifest without materials? Can there be consciousness without physical manifestation? [1] I'm ignoring open questions about determinism in physics since computers as we know them don't depend on that stuff.
