In recent years, theoretical and intellectual movements such as actor-network theory, new materialism, and philosophical animism have come to question some foundational aspects of the liberal humanist tradition, including human exceptionalism and the separation from the nonhuman world. It has been recognised that while these approaches have proved revealing and productive in thinking about the post-anthropocentric phase of posthumanism, Indigenous knowledges predate these theoretical formations in their challenge to anthropocentrism. Indigenous stories and practices have been pivotal points of power counteracting the epistemological privilege granted to European cultures and thought. In light of this recognition, the focus of this paper is a contemporary text by Khasi writer Janice Pariat, Everything the Light Touches (2023), which explores the question of human/nonhuman dualism, as inherited from the Enlightenment. It does this by not only revisiting the wisdom that resides within Indigenous communities, in particular the Khasi community to which the writer belongs, but also by reimagining the lives of two highly influential historical figures from the Enlightenment, German philosopher Johann Wolfgang von Goethe and Swedish botanist Carl Linnaeus. The novel, which deftly interweaves stories from different and disparate places and times, can be considered a daring experiment in narrative structure. It can also be regarded a meditation on the possibilities offered by literary imagination in the age of climate crisis. In response to the conference theme, this paper will examine how and why this recent novel by Pariat brings into focus Indigenous wisdom in juxtaposition with Enlightenment thought to examine some key concerns of posthumanism.
