The author opens with a brief account of, and motivation for, Łukasiewicz-style refutation calculi for making an r.e. list of the non-theorems of propositional calculi. He then uses Heyting algebras to develop refutation calculi for the intermediate logics: finite logics, LC, Yankov's logic, the logic of the weak law of excluded middle, Medvedev's logic, and certain logics without the finite model property.
