“Linguaggi scientifici e realtà. La voce del padrone di Stanisław Lem”

the paper reflects on the semiotic ideology of science starting from the novel His Master’s Voice, by Stanisław Lem. Of course, the semiotic ideology of the book is fictional. For this reason, in the paper, it will be considered a dummy semiotic ideology. The author reconstructs the epistemological conflicts between different scientists of his time, such as automata theory, structural linguistics, topology, and psychoanalysis, reflecting on the limitations of science in handling an intentional object such as an alien message and on the difficulties encountered by formal approaches to meaning. The book can be considered a mental experiment and shows how scientific semiotics itself can be considered a semiotic ideology.
