On Reduplication Allan T. Bäck

On Reduplication is a study of the logical properties of reduplicative propositions, that is, of propositions having qualifications, like 'Christ qua God is a creature' and 'being qua being is the subject of metaphysics'. The focus is on what ways qualifications change the truth value and the inference patterns of simple, categorical propositions. Reduplicative propositions occur frequently and importantly in both traditional and contemporary philosophical works.
