The bizarre story of how the planet Earth came to be represented on paper.
“You have shown me a strange image, and they are strange prisoners ... they see only their own shadows, or the shadows of one another, which the fire throws on the opposite wall of the cave....” (Plato, The Republic, Book VII)
Even on our 21st-century, plugged-in, wired-up, Googleable globe, Plato’s allegory of the cave – a Philosophy 101 workhorse that articulates human beings’ futile attempts to understand their universe – resonates. Climate change is real, until deleted Intergovernmental Panel on Climate Change e-mails raise the possibility that it’s not. The moon is lifeless and barren, until NASA finds “bucketfuls” of water near its south pole. Pluto is thought to be a planet, until it’s proved not to be a planet, and then, apropos of nothing, the Illinois state legislature votes to make it a planet again.
If there is an end to this stumbling in the dark that passes for reasoning, don’t look for it in geography. As told in Toby Lester’s compelling The Fourth Part of the World, the bizarre story of how Planet Earth came to be represented on paper would be funny if it hadn’t inspired and been inspired by genocide, slavery, and religious war.
