This paper argues that reading Margaret Atwood's post-apocalyptic novel, MaddAddam, through the theoretical lens of the Anishinaabe philosophy of Mino-Bimaadiziwin, or “the way of the good life,” highlights the complex means by which the novel is entirely composed upon the idea and necessity of interconnectivity, using it as a structuring device, a central thematic, and a means of plot resolution (Rheault 140). Critics have approached the novel (and the trilogy) from a variety of Euro-American philosophies, but with little input from Indigenous philosophies; in contrast, this paper argues that Mino-Bimaadiziwin clarifies MaddAddam's inventive use of discontinuous narrative, time, and multi-voiced discourse, as well as the novel's reliance on inter-species interconnectivity to resolve the plot. Subsequently, MaddAddam offers a sustained critique of, and alternative to, ingrained Euro-American ontologies of rigid binaries, linear time, and human exceptionalism. At the same time, the theoretical framework of Mino-Bimaadiziwin provides a concrete, comprehensive, and underrepresented approach to engage the issue of interconnectivity in the novel. As a result, this paper aims to participate in the necessary and valuable act of decolonizing academic ontologies by emphasizing the importance and need for Indigenous philosophies and ontologies in critical theory.
