This chapter shows how Derrida's deconstruction in Voiceand Phenomenon exposes a double necessity that undergirds Husserl's phenomenological inquiry in the “First Logical Investigation,” especially with respect to expression and indication. It turns to Derrida's reflections on the aporia of blindness in Memoirs of the Blind in order to further develop the logic of double necessity and to examine Derrida's divergence from Merleau-Ponty's thought. The chapter examines Derrida's critique of the auto-affective movement of temporalization in Voice and Phenomenon that reveals the impossibility of pure auto-affection. It explores the limits of Merleau-Ponty's phenomenology where he has moved beyond Derrida's deconstruction of Husserlian phenomenology. For Derrida, Merleau-Ponty's emphasis on speech and perception reveals his entrenchment in the phenomenological prioritization of presence; “soaring up to the sun of presence, it is the path of Icarus”.
