Abstract: Reading II.11 and II.12 in dialogue with posthumanist and ecological thought, this article argues that the Essays place us before a difficulty still faced by ethics today: the difficulty of articulating anarchic (without ground or why) responsibility to other beings with rational-scientific and deconstructive discourses concerning other creatures. In so doing, the Essays sketch out the idea of another humanitas that undoes the violent speciesism and metaphysics of humanism.
