Walking was not fast enough so we ran. Running was not fast enough, so we galloped. Galloping was not fast enough, so we sailed. Sailing was not fast enough, so we rolled merrily along on long metal tracks. Long metal tracks were not fast enough, so we drove. Driving was not fast enough, so we flew. Flying isn't fast enough, not fast enough for us. We want to get there faster. Get where? Wherever we are not. But a human soul can go only as fast as a man can walk, they used to say. In that case, where are all the souls? Left behind. They wander here and there, slowly, dim lights flickering in the marshes at night, looking for us. But they're not nearly fast enough, not for us, we're way ahead of them, they'll never catch up. That's why we can go so fast: our souls don't weigh us down.
