Are the administrative sciences anti-freedom? A relevant question in our emphatically modern world, seemingly ruled by a transcendent determinism. Yet the modern era promised not only science but freedom. Starting from these ideas, we are proposing a parallel dialectic on freedom that runs contrary to the supposed rift between rationalization as the enemy of freedom and emancipation as a quest for freedom. We will show that administrative sciences and concrete management have something in common: the technique that implies a dialectic of freedom.
