Philosophical SciFi in literature

[DavidS]

So, any fans of philosophical SciFi here, in the vein of Stanislaw Lem, Phillip K. Dick, the Strugatzkys, Isaac Asimov or you name it?

Got inspired to open this thread as I want to watch Ari Folmans "The Congress" (losely based on Lems "the Futurologic Congress"...)




I never really got 100% in touch with Hard-Fi/more technologically serious sci fi (like Ringworld) though.

Anyways, my favorites include:
Dick: Ubik, Martian Time Slip, (naturally) Blade Runner
Lem: Katar, Transfer, The Invincible, Pirx short stories.

especially transhumanist themes and the big "what am I?" in conflict with an ever more advanced and intelligent technology is very interesting to me.
