Solaris is an album based on the 1961 Polish philosophical science fiction novel by Stanisław Lem. The book centers upon the themes of the nature of human memory, experience and the ultimate inadequacy of communication between human and non-human species. In probing and examining the oceanic surface of the planet Solaris from a hovering research station the human scientists are, in turn, being studied by the sentient planet itself, which probes for and examines the thoughts of the human beings who are analyzing it. Solaris has the ability to manifest their secret, guilty concerns in human form, for each scientist to personally confront. Solaris is one of Lem’s philosophic explorations of man’s anthropomorphic limitations. First published in Warsaw in 1961.
