Locating Heidegger’s _kotoba_ between Actuality and Hollowness: The Way towards a Thinking Conversation with Japanese Philosophy

What is the philosophical significance of Heidegger’s interpretation of the Japanese notion of kotoba (言葉) for Japanese philosophy? Was his conversation with Tezuka Tomio a real dialogue or not? To answer to these correlated questions, I elucidate Heidegger’s 1954 essay “A Dialogue on Language” by following a topological mode of thinking, and I inquire into the way-making of a “thinking conversation”. First, I problematize whether Heidegger engaged in a genuine dialogue with Tezuka. To that end, I distinguish the hermeneutic horizon of the actual encounter between Tezuka and Heidegger from Heidegger’s essay which places Tezuka (the Japanese) and Heidegger (the Inquirer) in a fictional philosophical conversation. Second, I argue that Heidegger’s topological method of interpretating kotoba can be read as a poetic means of thematizing East-West dialogue. Third and finally, exploring the topological sense of kotoba, I engage with third generation Kyoto School thinker Ueda Shizuteru’sideaof“hollow words” of language, situated in a twofold view of the world. I conclude that the true character of Heidegger’s conversation with Tezuka can be identified neither in Heidegger’s “actual” encounter with Tezuka, nor merely in Heidegger’s “hollow” essay. Departing from Ueda’s account of kotoba, it appears that a genuine conversation with language can be located in the dialogue of actuality and hollowness, which finds it expression in poetic language.
