Inquirers into Wonder (Heidegger)

Only because of wonder, the revelation of Nothing, does the “Why?” spring to our lips. Only because this “Why?” is possible as such can we seek for reasons and proofs in a definite way. Only because we can ask and prove are we fated to become inquirers in this life. The inquiry into Nothing puts us, the inquirers, ourselves in question. It is a metaphysical one.

-- Heidegger, from "What is Metaphysics?"
