Jacques Derrida's deconstruction of Edmund Husserl's phenomenology takes issues with its ability to deal with the inseparable alterity belonging to difference. Whereas Derrida's proto-deconstructive critique of phenomenology presented itself as working within Husserl's intentions. Derrida's claim that Greek philosophy privileges speech in its interpretation of language therefore amounts to the claim that Greek philosophy privileges speech in its interpretation of speech. Derrida returns to Husserl's discussion of soliloquy in order to find the final adumbration in Husserl's text that establishes both the supposition of pure difference at the heart of Husserl's phenomenology and, by extension, the metaphysics that determines this phenomenology, together with its untenability in both. Derrida's deconstruction of the phenomenological voice purports to show 'logocentrism' and 'phonocentrism' at work in determining the limit of Husserl's phenomenology. And, by tying the centrisms to the historical predetermination of Western metaphysics, Derrida is committed to the presupposition of their role in determining the limit of Greek metaphysics as well.
