This chapter explores images of plant life in philosophy and literature with particular focus on the works of Friedrich Nietzsche and Jean-Paul Sartre. It pursues the question of what we can learn about the nature of the human being and its place in the world from plants and the way they are rooted in earth. Over the past half-century, many voices identify our disconnection from the earth with the centrality of technological progress, capitalist production, industrialization, and globalization that are essential to our modern self-understanding and way of life. What was supposed to be the root of human distinction has ended up uprooting us. Is this because we have a distorted view of what it means to be rooted in the first place, and our dependency on the rootedness of plant life? This chapter interrogates the metaphor of the root in Jean-Paul Sartre’s famous novel Nausea. Whereas Sartre considers the earth as an inert background in relation to human purposes: always there, meaningless, the earth is the static backdrop of our human drama, Nietzsche’s vegetal imaginary puts forward an idea of human life as deeply embedded in both earthly and planetary life.
