Even more so than radical translation did for Quine, radical interpretation plays an important role in Davidson's work, but the exact nature of this role is up for debate. Some see Davidson as using radical interpretation directly in his arguments against conceptual relativism and the possibility of massive error—-of most of our beliefs being false. But Davidson seems to explicitly reject this reading in "Radical Interpretation Interpreted".
There is also a more narrow and technical version of radical interpretation used by Davidson: given the speaker's attitudes of holding particular sentences true in particular circumstances--the speaker's hold-true attitudes--, the radical interpreter is to infer a theory of meaning--a truth theory meeting a modified version of Alfred Tarski's Convention T--for the speaker's idiolect. Ernest Lepore and Kirk Ludwig characterize this as inference from sentences of the form:
