Although philosophy of childhood has always played some part in philosophical discourse, its emergence as a field of postmodern theory follows the rise, in the late nineteenth century, of psychoanalysis, for which childhood is a key signifier. Then in the mid-twentieth century Philipe Aries’s seminal Centuries of Childhood introduced the master-concept of childhood as a social and cultural invention, thereby weakening the strong grip of biological metaphors on imagining childhood. Today, while philosophy of childhood per se is a relatively boundaryless field of inquiry, it is one that has clear distinctions from history, anthropology, sociology, and even psychology of childhood. This volume of essays, which represents the work of a diverse, international set of scholars, explores the shapes and boundaries of the emergent field, and the possibilities for mediating encounters between its multiple sectors, including history of philosophy, philosophy of education, pedagogy, literature and film, psychoanalysis, family studies, developmental theory, ethics, history of subjectivity, history of culture, and evolutionary theory. The result is an engaging introduction to philosophy of childhood for those unfamiliar with this area of scholarship, and a timely compendium and resource for those for whom it is a new disciplinary articulation.
