In this article, I first problematize the concept of rationality as educational ideal through the use of feminist philosophy. I then offer an alternative concept of rationality as educational ideal based on my reading of Catherine Malabou's work on plasticity, epigenesis, and rationality. In a last part, I explore the ontological and normative dimensions of this new concept of rationality through Maurice Merleau-Ponty's concept of "hyper-dialectics."
