“Dialogs” come from times when cybernetics seemed to offer infinite possibilities. This optimism, although moderated by the author, manifests itself in first chapters. Later, Lem argues with himself presenting his thoughts in a constant movement. The most interesting are analyses of society and its institutions - Lem is predominantly interested in human thought that could make the world livable. "Dialogs" were not entirely translated to English.
PHILONOUS: Greetings, dear friend. What are you pondering about so lonely in this beautiful park?
HYLAS: Ah, that is you? I am glad to see you. Last night I worked hard to develop an idea which promises infinitely much to mankind.
PHILONOUS: What kind of precious idea is that?
HYLAS: I arrived at the conviction (which actually is certainty) that people will some time achieve immortality.
PHILONOUS: Do I get this right? How is that, you are not unfaithful to materialism which you have hitherto lectured on, do you?
HYLAS: Never. My idea does not collide with materialism, on the contrary, it necessarily follows from it.
PHILONOUS: I am all ears. Do explain, my friend.
