With the introduction of modal operators and the proposed translation scheme, the modal structuralist is unable to provide a uniform semantics for scientific and mathematical theories. Only the latter, as opposed to the former, requires such operators. In fact, Field has argued that if modal operators were invoked in the formulation of scientific theories, not only their mathematical content, but also their physical content would be nominalized (Field 1989). After all, in that case, instead of asserting that some physical situation is actually the case, the theory would only state the possibility that this is so.
