There is a mystery at the heart of Plato’s Parmenides. In the first part, Parmenides criticizes what is widely regarded as Plato’s mature theory of Forms, and in the second, he promises to explain how the Forms can be saved from these criticisms. Ever since the dialogue was written, scholars have struggled to determine how the two parts of the work fit together. Did Plato mean us to abandon, keep, or modify the theory of Forms, on the strength of Parmenides’ criticisms? Samuel Rickless offers something that has never been done before: a careful reconstruction of every argument in the dialogue. He concludes that Plato’s main aim was to argue that the theory of Forms should be modified by allowing that forms can have contrary properties. To grasp this is to solve the mystery of the Parmenides and understand its crucial role in Plato’s philosophical development.

The Parmenides is, quite possibly, the most enigmatic of Plato's dialogues. The dialogue recounts an almost certainly fictitious conversation between a venerable Parmenides (the Eleatic Monist) and a youthful Socrates, followed by a dizzying array of interconnected arguments presented by Parmenides to a young and compliant interlocutor named “Aristotle” (not the philosopher, but rather a man who became one of the Thirty Tyrants after Athens' surrender to Sparta at the conclusion of the Peloponnesian War). Most commentators agree that Socrates articulates a version of the theory of forms defended by his much older namesake in the dialogues of Plato's middle period, that Parmenides mounts a number of potentially devastating challenges to this theory, and that these challenges are followed by a piece of intellectual “gymnastics” consisting of eight strings of arguments (Deductions) that are in some way designed to help us see how to protect the theory of forms against the challenges. Beyond this, there is precious little scholarly consensus. Commentators disagree about the proper way to reconstruct Parmenides' challenges, about the overall logical structure of the Deductions, about the main subject of the Deductions, about the function of the Deductions in relation to the challenges, and about the final philosophical moral of the dialogue as a whole.

A review of Plato's Parmenides, The Conversion of the Soul, by Mitchell H. Miller Junior. The Parmenides is seen as offering readers a chance to appropriate fully by critical and conceptual inquiry what was given in the Republic in the modes of image and analogy.

The Greek word eoikos can be translated in various ways. It can be used to describe similarity, plausibility or even suitability. This book explores the philosophical exploitation of its multiple meanings by three philosophers, Xenophanes, Parmenides and Plato. It offers new interpretations of the way that each employs the term to describe the status of their philosophy, tracing the development of this philosophical use of eoikos from the fallibilism of Xenophanes through the deceptive cosmology of Parmenides to Plato's Timaeus. The central premise of the book is that, in reflecting on the eoikos status of their accounts, Xenophanes, Parmenides and Plato are manipulating the contexts and connotations of the term as it has been used by their predecessors. By focusing on this continuity in the development of the philosophical use of eoikos, the book serves to enhance our understanding of the epistemology and methodology of Xenophanes, Parmenides and Plato's Timaeus.
