Summary: Infinite-valued Gödel logic, i.e., Dummett’s LC, is extended by projection modalities and relativizations to truth value sets. An axiomatization for the corresponding propositional logic (sound and complete relative to any infinite set of truth values) is given. It is shown that certain simple infinite sets of truth values correspond to first-order Gödel logics which are not recursively axiomatizable.
