" We don’t need other worlds. We need mirrors. We don’t know what to do with other worlds. One world is enough, even there we feel stifled. We desire to find our own idealized image; they’re supposed to be globes, civilizations more perfect than ours; in other worlds we expect to find the image of our own primitive past. Yet on the other side there’s something we refuse to accept, that we fend off; though after all, from Earth we didn’t bring merely a distillation of virtues, the heroic figure of Humankind! We came here as we truly are, and when the other side shows us that truth—the part of it we pass over in silence—we’re unable to come to terms with it! "

― Stanisław Lem , Solaris
