the author of some of the best science fiction ever, including 'solaris', the story of a planet with a sentient sea, which, annoyed at the radiation beamed at it by an orbiting spacecraft, manufactures stranage humanoids by probing the minds of the astronauts and sends them onboard, driving the astronauts to lunacy. for instance, one of the men finds his wife, who had committed suicide some years ago, keeps coming back on board as a humanoid. brilliant concept. i saw the andrei tarkovsky version. tarkovsky reminds me of g. aravindan, a mystic and poet of cinema, whose 'kanchana sita' and 'chidambaram' and 'vaastuhara' are among my favorite films of all time.
i remember another stanislav lem story: about a robot who writes poetry, in one case writing it with only words starting with 's'. i only remember a fragment: 'savage, spectacular suicide'.
