In this paper I argue that, to conceive transcendence, Levinas retrieves the Platonic concept of “separation” and deploys it in three ways: metaphysically, semantically, and affectively. Levinas finds in the interaction between being and the Good beyond being of Republic VI 509b a certain “formal structure of transcendence”—one in which a term is conditioned by another while remaining absolutely separated from it. This formal structure is subsequently deployed metaphysically, in the relation between creator and creature; semantically, in the relation between (...) meaning and sense; and affectively, in the relation between the desiring self and its desired aim.
