What does the silent planet tell us? The analysis of selected philosophical themes found in Stanisław Lem’s Solaris

The paper analyses selected philosophical aspects of Stanisław Lem’s Solaris. I argue that there is an interesting similarity between the history of “Solarist studies” – the fictional scientific discipline depicted by Lem and cognitive science. I show that both disciplines go through similar stages as they try to describe their main subject (the planet Solaris and human consciousness respectively). In the further part of the paper, I focus on two problems identified in cognitive science that can be directly related to the themes found in Solaris: the problem of the detection of intelligence and the problem of the notion of mental representations. I finish the paper by looking at the mysterious guests that stalk the main protagonists and show that they can be understood as heuristic models that are taken into account in the theories of mind uploading.
