TY - JOUR AU1 - Lewis, Frank AB - Parmenides’ Modal Fallacy Frank A. Lewis University of Southern California, School of Philosophy, Los Angeles, CA 90089-0451, USA fl ewis@usc.edu Abstract In his great poem, Parmenides uses an argument by elimination to select the correct “way of inquiry” from a pool of two, the ways of is and of is not , joined later by a third, “mixed” way of is and is not . Parmenides’ fi rst two ways are soon given modal upgrades – is becomes cannot not be , and is not becomes necessarily is not (B2, 3-6) – and these are no longer con- tradictories of one another. And is the common view right, that Parmenides rejects the “mixed” way because it is a contradiction? I argue that the modal upgrades are the product of an illicit modal shift. Th is same shift, built into two Exclusion Arguments, gives Par- menides a novel argument to show that the “mixed” way fails. Given the independent failure of the way of is not , Parmenides’ argument by elimination is complete.
