I show that Hanoch Ben-Yami’s so-called QUantified ARgument Calculus (QUARC) can be extended to what I call QUARC\(^{+}\) which I show to be intertranslatable with a version of first-order logic in which unary predicates are non-empty. Given this result, I show that QUARC\(^{+}\) is complete, propose an axiomatization of QUARC, and discuss the resulting expressive limitation of QUARC.
