I am not going to try to compare the 2002 Soderbergh film version, but I like how they both compare the human mind to an a nearly unknowable alien (ocean of clones that appear on the ship)

I haven't read or seen the full 1972 version, but does anyone know if this line is in Stanislaw Lem's book?

"“We're proud of ourselves. But when you think about it, our enthusiasm's a sham. We don't want other worlds. We want mirrors.” -it is from the 2002 screenplay, but I am curious if it has any analogue in the Polish book or Russian film.
