In the article ‘Stanislaw Lem’s philosophy of science’, the author concentrates on evolutionary fastening of Lem’s vision of the world in the first part of the text. In the second one, the author takes notice to the fact that Lem’s philosophy of science has certain related parts with Karl Popper’s philosophy of science. Both thinkers dealt with a common range of subjects and lots of their deliberations had a very similar expression. Undoubtedly, Lem was inspired by Popper but he was not an imitator of his statements. Lem, as an original visionary, in his thoughts used to leave the area of Popper-shaped philosophy and reached wider areas conceiving visions of the future science, that were characteristic to him. Lem’s vision of underdefined reality happening before our very eyes with the next dice rolls, makes us think of Popper’s criticism of faith in the absolute truth of scientific theories: we cannot know anything with a hundred per cent certainty. With reference to Lem’s thoughts, the author answers two questions in this text: Why falsification appears to work? Is it because the world is probabilistic? We are unable to gather complete information because of the system complexity we are in. If we were able to do it, would Popper’s falsification be invalidated?
