This paper starts from a brief sketch of the classical figure of critical educational theory or science (Kritische Erziehungswissenshaft). Critical educational theory presents itself as the privileged guardian of the critical principle of education (Bildung) and its emancipatory promise. It involves the possibility of saying "I" in order to speak and think in one's own name, to be critical, self-reflective and independent, to determine dependence from the present power relations and existing social order. Actual social and educational reality and relations are approached as a limitation, threat, alienation, reoppression or negation of ultimate human principles or potential. The task of critical educational theory becomes one of enabling an autonomous, critical, self-reflective life. While critique and autonomy have meanwhile become commonplace, and critique and autonomy are reclaimed and required from everybody, we should also consider the question of the relation between an institutional or ideological framework as that which claims to question this frame and to constitute its opposite. The trivialisation of critique is taken as occasion to recall Michel Foucault's analysis of power relations and especially his thesis according to which the government of individualisation is the actual figure of power. Starting from the framework offered by Foucault, it can be made clear that the autonomous, critical, self-reflective life does not represent an ultimate principle but refers to a very specific form of subjectification operating as a transmission belt for power. The autonomous, critical, self-reflective person appears as an historical model of self-conduct whereby power operates precisely through the intensification of reflectiveness and critique rather than through their repression, alienation or negation. This brings us back then to the question of how to conceive of the task of a critical educational theory at a time in which critique, autonomy and self-determination have become an essential modus operandi of the existing order.
