Can /his/ solve the Münchhausen trilemma?
The Münchhausen trilemma is that there are only three options when providing proof in this situation:
The circular argument, in which theory and proof support each other
The regressive argument, in which each proof requires a further proof, ad infinitum
The axiomatic argument, which rests on accepted precepts

I think we can only give a pragmatical solution: if you don't have a problem with the premises, then go on with the theory.
One could also say that some propositions are self-evident and therefore don't require a proof, but then it could be contested that self-evidence isn't a sufficient criterion of truth or that it's subjective or that it's not really a thing.
Become a coherentist.
Not all circular arguments are vicious - a system of accepted beliefs which are mutually justificatory can still be true without a foundation.
