An Interpretation of Pauli's Exclusion Principle

I. Pauli's exclusion principle can be understood as an instance of the subjectivity of our knowledge. We are built out of only a particular world constructed according to one of the non-combining patterns possible under the laws of quantum mechanics. Therefore we are capable of having sense perceptions of only that world.

II. Dirac's theory of the proton shows why Pauli's principle governs the world.
