Can Meaningless Statements Be Approximately True? On Relaxing the Semantic Component of Scientific Realism

First, I show that the semantic thesis of scientific realism may be relaxed significantly-to allow that some scientific discourse is not truth-valued-without making any concessions concerning the epistemic or methodological theses that lie at realism's core. Second, I illustrate how relaxing the semantic thesis allows realists to avoid positing abstract entities and to fend off objections to the "no miracles" argument from positions such as cognitive instrumentalism. Third, I argue that the semantic thesis of scientific realism should be relaxed because it is possible for scientific statements to be partially true, and hence approximately true, without being false.
