This contribution refuses two positions: one defends education against instrumentality, and the other reduces education to a political instrument. Alternatively, it recognizes instrumentality as precarious but necessary. Thus, with focus on populist articulations, education is instrumentalized as a demand to fix the people’s incompleteness as a totality. However, both education and the people are lacking totalities, and it is through their articulation as prosthetic bodies one to the other that they help each other to be, however without fully being.
