Elon Musk has some pretty concrete plans for the Red Planet. However, he mostly discusses technological and financial obstacles. I’m more interested in psychological and political challenges to living on Mars. And I found most insightful considerations from an unlikely source: Plato.
Plato’s Laws is about starting a new colony, the fictional city of Magnesia, on an isolated Cretan island. Many of the psychological and political difficulties that Magnesians would face can be juxtaposed to potential settlers on Mars.
The latest video on my YouTube channel is on possible cities on Mars.
