Central theme
A central question of the book is 'Why is there something rather than nothing?', which lies in the domain between philosophy and scientific cosmology. Gottfried Wilhelm Leibniz was the first to publish the question in 1714. In this book, the author records a quest to answer the question through a series of interviews and discussions. Some of the people interviewed are John Updike, David Deutsch, Adolf Grünbaum, John Leslie, Derek Parfit, Roger Penrose, Richard Swinburne, Steven Weinberg, and Andrei Linde. Along the way, Jim Holt also introduces the reader to the philosophy of mathematics, theology, physics, ontology, epistemology, and other subjects.

Review
"In “Why Does the World Exist?,” Jim Holt, an elegant and witty writer comfortably at home in the problem’s weird interzone between philosophy and scientific cosmology, sets out in search of such answers. He takes inspiration from readings of Heidegger and Sartre, and from something Martin Amis once said in a television interview: “We’re at least five Einsteins away from answering that question.”... Holt reminds us that no exploration of being — especially human being — can be separated from the human who undertakes it, complete with character and the play of moods. Updike felt that the universe had “a color, a quiet but tireless goodness that things at rest, like a brick wall or a small stone, seem to affirm.” Surely this was a mood, even a quirk of biochemistry, but it opens a perspective on the universe, too. The question of being itself, as Updike and Holt agree, can seem profound in one mood, vacuous in another."
