This book aims to expand on the notion of being, becoming, and being-becoming that manifests across the literature of liminality, crossroads and borderlands. Looking to overcome the limitations of these grounding concepts, the metaphor of the shadowlands is proposed. Moving away from dualities and binaries, challenging the spatial metaphors, which imply clear and defined boundaries and spring from an objective construction of reality, and coping with the idea of incompleteness, unfinishedness, are the challenges of the shadowlands. Through the prism of this newly conceptualised analytical and epistemological tool, the authors intend to grasp a fresh understanding of the processes of being, becoming and being-becoming in both their singular and multiple manifestations. As an epistemological concept, the shadowlands imply that anthropologists must not only identify these uncanny spaces of junction in their research, but also shadowlands in the ethnographic papers that they produce. In addition to a better understanding of the continuous fabrication of temporalities and being-becoming, the concept puts into perspective the discipline of anthropology itself. Throughout the chapters, the different authors permit to grasp the various applications of the shadowlands, allowing to project the concept in particular contexts and through specific angles of analysis.
