"Why is there anything at all?" (or "why is there something rather than nothing?") is a question about the reason for basic existence which has been raised or commented on by a range of philosophers and physicists, including Gottfried Wilhelm Leibniz,"Principles of Nature and Grace", 1714, Article 7. Ludwig Wittgenstein,"Not how the world is, is the mystical, but that it is." Tractatus Logico-Philosophicus 6.44 and Martin Heidegger, the last of whom called it "the fundamental question of metaphysics".Martin Heidegger, Introduction to Metaphysics, Yale University Press, New Haven and London (1959), pp. 7–8.
