WebIn this paper, we provide a self-reference-free proof of the second incompleteness theorem from Tarski’s theorem on the undefinability of truth. Thus, we do not aim to eliminate self-reference altogether.

In mathematics, Tarski's theorem, proved by Alfred Tarski (1924), states that in ZF the theorem "For every infinite set , there is a bijective map between the sets and " implies the axiom of choice. The opposite direction was already known, thus the theorem and axiom of choice are equivalent.
