Theorem
The Axiom of Choice can be neither proved nor disproved from the axioms of Zermelo-Fraenkel set theory.
Proof
You can help $\mathsf{Pr} \infty \mathsf{fWiki}$ by crafting such a proof.
When this page/section has been completed, {{ProofWanted}} should be removed from the code.
If you would welcome a second opinion as to whether your work is correct, add a call to {{Proofread}} the page (see the proofread template for usage).
Historical Note
Kurt Gödel showed that the Axiom of Choice is not disprovable in Zermelo-Fraenkel set theory.
Paul Cohen showed that neither is the Axiom of Choice provable in Zermelo-Fraenkel set theory.
