This paper looks at the theoretical practice of “critique” in the work of Michel Serres and Anna Lowenhaupt Tsing, focusing especially on the notion of parasitism and femininity. The co-reading shines a light on the crossings of their approaches, like a critique of “laboratory” - like conditions and a masculinist understanding of rationalism. Furthermore, it brings attention to some productive divergences. With Tsing’s approach, this paper reflects critically on Serres’s understanding of femininity and extents his philosophical elaboration of parasites and (...) fungi with a feminist, ecological and anthropological perspective. Serres, on the other hand, contributes with his multi-faceted figure of the “third” crucially to structural reflections on the relation between fungi and femininity, as well as to an understanding of “critique” from the “middle”, beyond the “battle of the two”.
