The aim of this article is to examine the influence of the contemporary speculative philosophy on the neo-fantastic fiction (Le monde enfin by J.-P. Andrevon). The speculative philosophy presents the modern world as the source of cosmological horror for the human being. In my analysis, I focus on two anxiety-provoking motifs present both in speculative philosophy and Andrevon’s novel: the end of the anthropocentric world and the beginning of a new, inhuman world, dominated by nature.
