The significance of this conclusion is that it allows Davidson to draw on the work of Alfred Tarski in giving the nature of a theory of meaning. Tarski showed how we can give a compositional theory of truth for artificial languages. Thus, Davidson takes three questions to be central to radical interpretation. Firstly, can a theory of truth be given for a natural language? Secondly, given the evidence plausibly available for the radical interpreter, can they construct and verify a theory of truth for the language they wish to interpret? Thirdly, will having a theory of truth suffice for allowing the radical interpreter to understand the language? Davidson has shown, using the work of Tarski, that the first question can be answered affirmatively.
