In this chapter I introduce the work of the French philosopher Bernard Stiegler. I present his key ideas and terminologies, as well as the main influences on his thought. The focus is on the role which technologies – through processes of education – play in the constitution of subjectivity. I also zoom in on Stiegler's analysis of the digitization of our contemporary world, and which role education has to play. I finish by considering the possibilities and limitations of Stiegler's ideas for educational philosophy and theory.
