“Heidegger says that “the fundamental question of metaphysics” is “why is there anything at all rather than nothing?” The fundamental question is not, as Plato thought, “what” a thing is (every Platonic dialogue is about that, about an essence, a definition, a concept, such as justice or piety or learning) but why it exists, why anything exists. Plato never asked that ultimate question. And the answer is God.”
