This paper explores the theme of education and the posthuman from the perspective of French philosophy. It addresses a crisis in eduction today identified by Michel Serres: now that knowledge is widely and freely accessible through information technologies, what is the purpose of education? A response is developed through three conceptual terms prefixed with ‘post’: the postmodern, the posthuman, and through the proposed idea of ‘postinformation.’ The background to the problem is sketched in terms of the ‘postmodern,’ with reference to (...) Lyotard’s influential The Postmodern Condition. A theory of the posthuman, which synthesises Stiegler’s ‘exorganism’ and Floridi’s ‘inforg’, is then sketched in response to Serres’ question of who the subject of education is today. The response to the crisis the paper proposes is that the purpose of education today is not to transmit information, but to help shape posthuman subjects able to process it effectively. This means helping them to learn how to navigate the complex informational networks we now inhabit so that they are able to flourish. The concept of postinformation is designed to help facilitate this educational shift in perspective. Postinformation concerns not just informational content, but the constitutive function of information and information technologies. (shrink)
