And yet we knew, for a certainty, that when first emissaries of Earth went walking among the planets, Earth's other sons would be dreaming not about such expeditions but about a piece of bread.

Are we to grow used to the idea that every man relives ancient torments, which are all the more profound because they grow comic with repetition? That human existence should repeat itself, well and good, but that it should repeat itself like a hackneyed tune, or a record a drunkard keeps playing as he feeds coins into the jukebox.
