ABSTRACT. The author attempts to clear up some of the misunderstandings, to provide a satisfactory formulation of the thesis of indeterminacy of translation in non-naturalistic terms, to demonstrate how a naturalistic substitute can be derived from this formulation, to refute the best known arguments for and against the thesis, and to show how it relates to the thesis of indeterminacy of reference, the theses of semantic and epistemic holism and to the thesis of underdetermination of theory by data.
