“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.”

“We take off into the cosmos, ready for anything: for solitude, for hardship, for exhaustion, death. Modesty forbids us to say so, but there are times when we think pretty well of ourselves. And yet, if we examine it more closely, our enthusiasm turns out to be all a sham. We don't want to conquer the cosmos, we simply want to extend the boundaries of Earth to the frontiers of the cosmos. For us, such and such a planet is as arid as the Sahara, another as frozen as the North Pole, yet another as lush as the Amazon basin. We are humanitarian and chivalrous; we don't want to enslave other races, we simply want to bequeath them our values and take over their heritage in exchange. We think of ourselves as the Knights of the Holy Contact. This is another lie. We are only seeking Man. We have no need of other worlds. A single world, our own, suffices us; but we can't accept it for what it is. We are searching for an ideal image of our own world: we go in quest of a planet, a civilization superior to our own but developed on the basis of a prototype of our primeval past. At the same time, there is something inside us which we don't like to face up to, from which we try to protect ourselves, but which nevertheless remains, since we don't leave Earth in a state of primal innocence. We arrive here as we are in reality, and when the page is turned and that reality is revealed to us - that part of our reality which we would prefer to pass over in silence - then we don't like it anymore.”

“We don't want to conquer the cosmos, we simply want to extend the boundaries of Earth to the frontiers of the cosmos.”

“Of the two powers, the two categories that take possession of us when we enter the world, space is by far the less mysterious. . . . Space is, after all, solid, monolithic. . . . Time, on the other hand, is a hostile element, truly treacherous, I would say even against human nature.”

“Is a mountain only a huge stone? Is a planet an enormous mountain?”

“We have no need of other worlds. We need mirrors. We don't know what to do with other worlds. A single world, our own, suffices us; but we can't accept it for what it is.”

“Giese was an unemotional man, but then in the study of Solaris emotion is a hindrance to the explorer. Imagination and premature theorizing are positive disadvantages in approaching a planet where—as has become clear—anything is possible... The fact is that in spite of his cautious nature the scrupulous Giese more than once jumped to premature conclusions. Even when on their guard, human beings inevitably theorize.”
