 “First philosophy” in the Western tradition is ontology, which asks the question of “being qua being,” and tends to answer this question either in terms of the most universal “being-ness” or in terms of the “highest being.” For Aristotle, the primary category of being is “substance,” ambiguously thought in its primary sense as the particular entity (e.g. Socrates) and in its secondary sense the universal that makes that entity what it is (e.g. human being), and the highest being was the “unmoved mover.” Greek ontology later influenced the Christian theological tradition to think of God as the “highest being,” such that the dual threads of the Western tradition as a whole took shape as what Heidegger calls “onto-theology.” Hence, the fundamental philosophical question of the onto-theological mainstream of the West is, “What is being?” On the other hand, the counter-question which the Kyoto School finds in the East is, “What is nothingness?” In place of an ontology, first philosophy in the East is more often a “meontology”: a philosophy of non-being or nothingness.
