Which of Platos works mentions Atlantis?
I’m fairly sure it was first mentioned in the “Timaeus” dialogue and then again in “Critias”. To be honest I’m not much of a Plato fan, but as so much of his thinking has been the bases of western thinking all his work is worth a read. I never agree with his conclusions, but there’s no doubt that he often asks the right questioned. Plato wasn’t much of a fan of the essay so you have to be prepared to learn his view points through didactic stories and fictional dialogues. No matter what it is he’s describing there is always the background noise of his “perfect forms” concept intrinsically built in to the work. Everything is the shadow on the cave analogy with him. If I remember rightly Atlantis was used as a negative antithesis to the perfection of an opponent city, the then young and exceptionally good Athens.
