"To radicalize the question of phenomenology is not only to aim for a pure phenomenality but to seek out the mode according to which it originally becomes a phenomenon -- the substance, the stuff, the phenomenological matter of which it is made, its phenomenologically pure materiality. That is the task of material phenomenology. Prior to this being-toward-the-outside in which everything is properly speaking placed outside of itself and in which every reality is a priori emptied and dispossessed of itself and thus becomes its contrary, an irreality, and prior to the abandonment and undoing that is called death and that would be unable to exist on its own, material phenomenology is devoted to the discovery of the reign of a phenomenality that is constructed in such a surprising way that the thought that always thinks about the world never thinks about it. To the internal structure of this originary manifestation, there belongs no Outside, no Separation, no Ek-stasis. Its phenomenological substance is not visibility. None of the categories that have been used by philosophy since the Greeks at any rate, are appropriate for it."
