A phenomenological inquiry into the benefits and limitations of formal analytic reasoning is developed in reliance upon the criticism of reason by Husserl and his students which is respecified ethnomethodologically by examining occasions of philosophers work in its actual course. Liberman engages in a dialogue and debate with Husserl Heidegger Levinas Merleau-Ponty and Derrida for the purpose of adding an ethnomethodological vision of the orderliness of ordinary philosophical affairs to the philosophical anthropology of reason.
