"It was a depressing sight. We went out in the crowds, our arms laden with parcels, coming and going from the big department stores that were open day and night, and while we were scanning the neon signs that climbed higher and higher up the skyscrapers and notified us constantly of new products that had been launched, we’d suddenly see it advancing, pale amid those dazzling lights, slow and sick, and we could not get it out of our heads that every new thing, each product that we had just bought, could similarly wear out, deteriorate, fade away, and we would lose our enthusiasm for running around buying things and working like crazy—a loss that was not without consequences for industry and commerce."

Reflections on the uneasy relationship between the Earth and the moon.
