Today, we are held to live in the Anthropocene, bringing to an end modern binary imaginaries, such as the separation between Human and Nature, and with them Western assumptions of progress, linear causality and human exceptionalism. Much Western critical theory, from new or vital materialism to post‐ and more‐than‐human thinking, unsurprisingly reflects this internal crisis of faith in Eurocentric or Enlightenment reasoning. At the same time, a radically different critique of modernity has gained prominence in recent years, emerging from critical Black studies, which places the Caribbean at the centre of the development of a new and distinct mode of critical thought. In attempting to grasp the ways in which Caribbean thought and practice have been seen to enable a distinctive alternative non‐Eurocentric imaginary, this paper heuristically sets out a paradigmatic framing of ‘abyssal geography’. We emphasize two key points. The first is that abyssal thought is not grounded in abstract and timeless philosophical assumptions but figuratively draws upon aspects of Caribbean practices of resistance and survival, for example, from the Middle Passage, Plantation, carnival, creolization, dance forms and speculative fiction. The second is that abyssal work engages the legacies of modernity and coloniality by explicitly seeking to question the lure of ontology: seeking to disrupt, suspend and to problematize the modern project of the human and the world.
