Published before the call for chapters for Postdigital (Re)imaginations: Critiques, Methods, and Interventions, this chapter outlines its editors’ initial ideas behind the volume. Placing imagination at the heart of scientific discovery and knowledge development, the chapter links imagination to human emancipation and emancipatory knowledge. Following David Graeber, it argues that popular imagination is one of the most underused human resources and mobilizes postdigital critical pedagogy to start using those resources more extensively. The chapter then situates these ideas in a postdigital context, arguing that postdigital imaginations are an assemblage of immaterial and material forces. After a brief review of existing postdigital research in the field, the chapter concludes with an emphasis on deep relationships between postdigital imagination, emancipatory knowledge interest, critical social science, and philosophies that challenge the powers that be. Arguing that we need to find our vocation not as detached birds-eye-view spectators of postdigital realities, but as partners with multiple others in our collective imaginations of postdigital futures, the chapter sets the tone for Postdigital (Re)imaginations: Critiques, Methods, and Interventions.
