"Boredom is the entrancement of the temporal horizon, an entrancement which lets the moment of vision belonging to temporality vanish. In thus letting it vanish, boredom impels entranced Dasein into the moment of vision as the properly authentic possibility of its existence, an existence only possible in the midst of beings as a whole, and within the horizon of entrancement, their telling refusal of themselves as a whole."
-- Martin Heidegger, The Fundamental Concepts of Metaphysics §34
