Parmenides' first 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 contradictories 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. This same shift, built into two Exclusion Arguments, gives Parmenides 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.", pages = "1-8(8)", url = "http://www.ingentaconnect.com/content/brill/phr/2009/00000054/00000001/art00002" doi = "doi:10.1163/156852808X375228" }
