The awe with which Plato regarded the character of “the great” Parmenides has extended to the dialogue which he calls by his name. None of the writings of Plato have been more copiously illustrated, both in ancient and modern times, and in none of them have the interpreters been more at variance with one another. Nor is this surprising. For the “Parmenides” is more fragmentary and isolated than any other dialogue, and the design of the writer is not expressly stated.
