Plato doesn't want anybody to know for all time whether it's true or false. He is pushing at the limits of what philosophical discourse might look like. Critiassus was ahead of the army in making a very different ideal republic. And I think Socrates himself, certainly Plato, agreed with almost everything that Criti has said about the ideal state. But he does not want to go so far as to be the mouthpiece of it.
Melvyn Bragg and guests discuss Plato's account of the once great island of Atlantis out to the west, beyond the world known to his fellow Athenians, and why it disappeared many thousands of years before his time. There are no sources for this story other than Plato, and he tells it across two of his works, the Timaeus and the Critias, tantalizing his readers with evidence that it is true and clues that it is a fantasy. Atlantis, for Plato, is a way to explore what an ideal republic really is, and whether Athens could be (or ever was) one; to European travellers in the Renaissance, though, his story reflected their own encounters with distant lands, previously unknown to them, spurring generations of explorers to scour the oceans and in the hope of finding a lost world.
The image above is from an engraving of the legendary island of Atlantis after a description by Athanasius Kircher (1602-1680).
