Is Consciousness Emergent? A Test to Prove It
The question is, how does consciousness arise in biological systems? There are at least two theories that account for consciousness. One is the idea that something is added to the body—an élan vital, a soul, or an independent mind (mind/body dualism). The other idea is that complexity (i.e., consciousness) emerges from the interactions of simple parts. Is there a way to choose one of these as being correct? Yes, by hypothesizing an emergent consciousness in a system that is not yet conscious—the computer. If we hypothesize that consciousness will emerge in a computer, given enough component parts, we can determine by rigorous testing if the hypothesis is proved. If the test proves that consciousness emerges in a computer, we will have proved that a soul is not necessary for consciousness—neither in computers nor in humans.
