In one of its simplest formulations, the quinean thesis of the empirical equivalence of theories claims that, given a theory T that accounts for a set of observations O, it is possible that there is a different logically incompatible theory T* that is empirically equivalent with T, i. e.it accounts for the same set O of observations. The aim of this paper is to examine the forceful consequences of this claim for a naïve scientific realism; this task will require a rephrasing of the empirical equivalence thesis in more accurate terms and an appraisal on its plausibility. I shall conclude that the empirical equivalence thesis does not have a logical-philosophical character, as those upon which it rests (underdetermination of theories by experience, epistemological holism), but a practical one, and that it qualifies over the actual possibilities for observation and testing; this argument will also be used to show how some sort of realism might be preserved, despite some of Quine’s assertions.
