If they think they have hands, then they really do have hands, if they think they have hair then they really do have hair, and so on. If this is the case, then the Matrix Hypothesis is therefore not a skeptical hypothesis but rather a metaphysical one. To explain this complex line of reasoning, Chalmers breaks down the Metaphysical Hypothesis into three different hypotheses: the Creation Hypothesis, the Computational Hypothesis, and the Mind-Body Hypothesis. He suggests that if he can prove all three of them coherent, show that their possibility cannot be ruled out, and show that none of them are skeptical in nature, then we can still be confident that all of our prior beliefs are still correct even with the possibility all of these hypotheses being true. After proving the coherence of the Metaphysical Hypothesis, Chalmers will then show its equivalence to the Matrix
