H.G. Wells: The Country of the Blind
"Over the mountains I come," said Nunez, "out of the country beyond there—where men can see. From near Bogota, where there are a hundred thousands of people, and where the city passes out of sight."

What would become of a community if its members were somehow deprived of sight? How would society evolve in the absence of the very concept of visibility? And what if, one day, a sighted outsider suddenly found himself in this country of the blind?
