The author of the article discusses post-anthropocentric threads in Kornel Filipowicz's stories and proved that describing the writer as posthumanist, characterized by contemporary ecological sensitivity, is possible on the condition of noticing the aporia between zoocritical narratives and his passion for fishing. The author of Unshakable Landscape has commented on the moral dilemmas associated with fishing and depriving them of their lives several times. The awareness of the existence of aporia between the desirable relations between humans and animals, presented in some of the stories, and angling practices, means that Filipowicz does not hide as a progressive writer who follows a fashionable theme. He remains an artist who faces dilemmas that also occupy animal activists today. The author of the article reconstructs Filipowicz's environmental awareness, referring to his writing output and biography by Justyna Sobolewska, checks how the protagonists of the stories treat fish and other animals, and discusses strategies for writing about the problem of violence against animals.
