As the ideological constructor of the destruction of colonised peoples and knowledge, Western philosophy must bear its burden for complicity. Decoloniality is amid the discourses of critique contra modernity and its denigration of the colonised. In the South African academy, for instance, much support has been validly rendered to decoloniality, consequently those employing “Western” frameworks should be challenged to constant re-evaluation. Here, the virtues and vices of decoloniality will not be considered. Rather a discernment will be undertaken of the “epistemic (...) worth” of conducting – specifically mediaeval and Western – philosophical research amid calls for the decentring of Western epistemological dominance, within the tradition of Saint Thomas Aquinas in the decolonial milieu. The argument is proffered – from multifold perspectives – that Aquinas, as both pre-modern and pre-colonial, does have relevance to the decolonial academic climate. The case is defended that Arabic philosophers importantly influenced Aquinas’ work, thus, demonstrating his openness to non-Western thought. Furthermore, from an epistemological perspective, it is contended that Aquinas’ placing of the subject at the focal point of adequations to truth by credencing the situatedness of the perceiver, deconstructs modern objectivity, which in itself has caused considerable damage to non-Western epistemologies. Aquinas’ epistemic relevance in this context, it is argued, may contribute to a median between demonstrable science and the multi-layered context of the epistemic subject. (shrink)
