A new, revised edition of one of the most important books ever written on Parmenides, including a New Introduction, Three Supplemental Essays, and a previously unpublished Essay by Gregory Vlastos. Originally published in 1970 and widely cited and discussed since then in the literature on Parmenides and on the Presocratics, The Route of Parmenides has been out of print for over three decades. This new edition—the first in paperback—includes a new introduction, and reprints of three essays by the author that significantly enhance and extend the argument of the original edition.
