Now available on the internet:
It is very important to realize that Plato did not make up a simply invented story. It is more complicated. Gomperz: "Plato believed that he had discovered some of the essential features of his political ideal in the dim beginnings of his native city."
This is the crucial sentence: Plato did not simply make it all up. He himself believed major parts of it, if not all, and thus was in error if it is not true. And being in error is something totally different than deceiving.
And: "We should be glad to know how far Plato's fiction is based on popular legend; how far the belief in an extensive country in the West rests on the presupposition of a not wholly unsymmetrical distribution of land between the Eastern and Western hemispheres; how far the fact, now attested by documentary evidence, of an incursion into Libya and Egypt made by conquering "sea-nations" coming from the West. But on all these points we are left to uncertain conjecture."
So, it is our task to see whether we can bring more light into this question.
