Plato''s Forms in Transition : A Reading of the Parmenides

Samuel Rickless argues that the main point of Plato's Parmenides is to change our conception of the Forms by granting that they can have contrary properties. With the help of his study, we can understand exactly why Plato wrote the Parmenides and what role it played in his philosophical development.

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.
