If computation is multiply realisable, it never reduces to any particular physical behaviour, even if it always instantiated a such > I recall that you aren't committed to CTM per se, but > if what you say about mathematics is true, and only the physical is > real, wouldn't it follow a priori that CTM just eliminates the mind? No. Every running programme is physical.
