Gilles Deleuze and Félix Guattari argue that a free flow between becomings and becoming imperceptible is desirable between people in education, within societies, and among societies. Deleuze, however, came to believe that reactive forces triumph over active ones, and that the above-mentioned free flow is rare, though possible. It is therefore dangerous to think, from a Deleuzian perspective, that such a flow would be a more or less easy way out of reactive forces. It is thus problematic that a post-humanist such as Rosi Braidotti, who draws on Deleuze’s work, believes that she offers a way out of reactive forces. Such thoughts can lead, harmfully, to a one-sided view of affirmation, joy and happiness, on the one hand, and to dead-end utopias on the other, as expressed by educational post-humanists such as Nathan Snaza and John A. Weaver, who assert the promise that posthumanism—with its one-sided emphasis on joyful affirmation—will take us back to the Garden of Eden. Instead of misrecognising reactive forces, Deleuze argues that human beings should respond responsibly to both active and reactive forces through thinking. Deleuze also argues that there is no certainty concerning how a free flow between perceptible and imperceptible becoming can be aroused, nor concerning how it can be sustained—it is rather an open-ended and never-ending process in education, within society at large and between societies, on the one hand, and a possibility actualized by a few on the other.
