We don’t want to conquer space at all. We want to expand Earth endlessly. We don’t want other worlds; we want a mirror. We seek contact and will never achieve it. We are in the foolish position of a man striving for a goal he fears and doesn’t want. Man needs man!
—  Solyaris (film) by Andrei Tarkovsky (based on the novel Solaris by Stanisław Lem)
