This paper consists in an attempt to refute Quine's principle of the indeterminacy of radical translation. The structure of the argument is as follows. The demonstration of the principle in Quine's work rests on certain conception of the process of radical translation. This conception can be maintained only if certain presuppositions are made concerning the nature of language and its speakers. However, if those presuppositions are adopted, there is no reason for not accepting also other presuppositions, which would invalidate Quine's demonstration.
