As early as Plato and as recently as current scholarship, readers of Parmenides have diagnosed tensions of one sort or another between his ontological views and the language through which he expresses those views. In the first instance, this article examines earlier claims for such tensions and argues that they are predicated on problematic assumptions concerning Parmenides’ ontological commitments or his strictures regarding the use of language. In the second instance, however, it argues that Parmenides’ Way of Reality does indeed confront us with tensions between language and doctrine, that these tensions are more pointed and sustained than scholars generally recognize and that they can be identified independently of specific or determinate elaboration of Parmenides’ precise ontological views. This analysis discloses a reflective preoccupation with, and a consistent attitude towards, the scope and limitations of human language. Parmenides persistently evinces his awareness that his description of what-is proceeds through expressive measures that are imported with difficulty from a different domain and, consequently, are limited, indirect and often figurative. The article closes by pointing to a meaningful (but partial) affinity between Parmenides and those Platonists who placed their own ultimate philosophical and ontological principle beyond the expressive reach of words.
