Abstract

The notion of stimulus meaning, a key notion for Quine's Indeterminacy of Translation thesis, has undergone an essentiaJ change fi'om the beginning of the nineties. Then, this essay offers an expository work oj this change (its origin and motivations) and its final result. Th~ main aim of this essay is to show the validity of the reasons that forced Quine to modify his stimulus meaning notion and the failure of its substitutes (global stimulus, stimulus range, and perceptual similarity) to solue the problems they were thought to give an account of. Moreover, these new notions make the Indeterminacy Thesis, mainly the Inscrutability of Reference Thesis, face new problems and, if I'm right, unsolvable ones.
