Solaris, his most recognised novel, was adapted into a movie twice, so we can be pretty certain that Mr Reeves likes it, all the more so since a bunch of his Hollywood buddies were in the more recent one. We can definitely entertain the hope that George Clooney would have discussed Solaris with Keanu. Who knows, the famous actors perhaps even discussed Lem’s most poignant passage:
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 civilisation 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.
When I first read Solaris, I highlighted these lines with tacky pink marker. When I first saw The Matrix, Lem’s books were the first association I made. Not only Solaris, but this particular quote, which deserves to be recalled whenever exploring space or earth.
