The essays in this dossier are the result of the course “Interreligious and intercultural dialogue from a decolonial perspective”, which took place between May and June 2017 at the CEIICH in the UNAM. In this course, I proposed to link a decolonial theoretical perspective to the topic of “intercultural dialogue” and, beyond, to “interreligious dialogue”; anyhow, this last topic turned out to be the point of departure to explore more profound dialogues, linked no only to religious phenomena but to sacred traditions and spiritualities. During the course, emphasis was put on this last aspect due to the fact that the topic of “the Divine” (in its different expressions), although central to decoloniality, has been poorly studied. Moreover, it has been marginalized within secularized social sciences —and this not just in Mexico, but in most occidentalized universities throughout the globe. This vacuum towards the study of “the Divine” —and, beyond, its limitation through a concept of culture (which is, at the same time, associated to the colonized and to the “other” of modernity)— led the participants of this volume to research deeper that which philosopher Enrique Dussel has described as the “spaces denied and oppressed by modernity”.
