Prior to writing the Sophist, Plato seemingly found his former metaphysical
theories to be untenable in the Parmenides in which he introduced issues with the
theory of the Forms.1 To address these specific issues, Plato wrestled with the
monism of the Parmenidean doctrine and its metaphysical ontology. In this essay,
I will examine the debate of whether Plato takes the Parmenidean doctrine
seriously in the Sophist. The views of Lesley Brown and Mary Louise Gill
conclude that Plato was not truly attempting a dissection and complete
understanding of Parmenides’ poem, which thereby made it effortless for him to
reject the view. Brown holds that Plato did not understand the metaphor’s
implications in its entirety, while Gill maintains that the metaphor was taken much
too literally. I oppose both views and claim that Plato did attempt a serious
understanding of monist ontology, and that whether the Parmenidean passages
were taken out-of-context is not the case.
