In this article, Toshiya Ueno proposes to bring in dialogue Félix Guattari's ecological thought with the post-Fukushima novella Chernobyl II published in 2014 by the Fukushima-born writer and media activist Eiichi Seino. Drawing in particular on Guattari's Three Ecologies and Chaosmosis, Ueno shows how Chernobyl II resonates with the notion of production of subjectivity, a process of collective individuation taking the form of a particular ambiance. In conclusion, Ueno argues that while Guattari's ecosophy should not be understood as a call for a planetary civilization, it nonetheless allows us, as demonstrated in the analysis Chernobyl II, to point at a practice of planetary love by definition ontologically prior to an ethical and political. Planetary love points at another non-human process of subjectivation embracing a chaotic movement of becoming, a becoming cosmic or a cosmo-politics. The novel thus does not provide any answer as such, only imposing on us, the readers, a strange perplexity and an imperative to think and act transversally, not starting from a moral system or political ideology but from the affective and aesthetic value of incorporeal universes after Fukushima.
