The Vegetal Turn is driven by this new, eclectic, mounting wave of theoretical and practical interest in the complexities and peculiarities of plant life, plant-human relations, plant-nonhuman relations, and plant-mediated human relations. From a mostly philosophical perspective, this volume provides a snapshot of that mounting wave in action, its kaleidoscopic interests and spreading trajectories, its less-than-fully-disciplined methods and approaches, and its central conceptual and practical aspirations. This chapter introduces the volume.
