title: Quasi-Truth as Truth of a Ramsey Sentence
creator: Lutz, Sebastian
subject: Logical Positivism/Logical Empiricism
subject: Structure of Theories
description: I show the quasi-truth of a sentence in a partial structure to be equivalent to the truth of a speciﬁc Ramsey sentence in a structure that corresponds naturally to the partial structure. Hence quasi-truth, the core notion of the partial structures approach, can be captured in the terms of the received view on scientiﬁc theories as developed by Carnap and Hempel. I further show that a mapping is a partial homomorphism/isomorphism between two partial structures if and only if it is a homomorphism/isomorphism between their corresponding structures. It is a corollary that the partial structures approach can be expressed in ﬁrst or second order model theory.
