This article analyses the relationship between humans and animals, and more importantly between humans and their animality. Concretely, this project proposes an ecocritical reading of fin de siècle gothic fiction, as it provides insight on the ideological foundation of humanity’s anthropocentric relation towards the environment. Through the analysis of the gothic hybrid monster, it is possible to grasp society’s interpretation and assimilation of Darwin’s revolutionary discoveries. However, not all gothic writers assimilated the apparent artificiality of humanity’s superiority in the same way. Thus, I hereby argue that rejection and fear is not the only response to the monstrous hybrid in fin de siècle gothic fiction. On the contrary, there are also critical voices who understood this new Darwinian human-hybrid identity as an opportunity to renew human relations towards nature. Therefore, I analyse the constructions of and reactions to the hybrid monster in Bram Stoker’s Dracula and Richard Marsh’s The Beetle against Vernon Lee’s Prince Alberic and the Snake Lady. By doing so, I aim at revealing and ultimately challenging the main dualism that sustains the hierarchical organization of the species: the privileging of culture over nature and reason over animality. The gothic genre is indeed characterised by the blurring of boundaries. Consequently, it reveals the human as irrational, the monster as natural and culture as repression, suggesting the need for the reconstruction of human identity and its place in the world.
