Georg Henrik von Wright developed what he called a "Truth-Logic" by adding a truth operator "T" and appropriate axioms and rules to a standard system of propositional logic. Much more attractive than this basic system of von Wright's "Truth-Logic", however, is its extension to quantificational contexts which allows highly interesting philosophical applications. The paper reveals several shortcomings of von Wright's quantificational version of his "Truth-Logic" and shows how to avoid them without giving up the basic idea of a Logic of Truth.
