by Jim Holt (2012). Personal account of contemporary attempts by philosophers and physicists to deal with the deepest ontological puzzle of them all “Why is there something rather than nothing?”. Written by an ex-philosopher as a sort of travelogue, interviewing Andre Linde, Adolf Grunbaum, Richard Swinburne, Roger Penrose (a neo-Platonist!), David Deutsch, Steven Weinberg, John Leslie and Derek Parfit, and interspersed by the death of his dog and his mother, it could also be subtitled Philosopher’s Conceit as it shows up in stark detail the inability of arm-chair philosophizing to extend the limits of what we know beyond those limits already encountered by Aristotle, Descartes and Kant. For in the end, answering this question in a definite way falls outside of mathematics, cosmology or physics. One is finally left with either a circular argument, an infinite regress or a brute fact (the world exist). The most compelling argument is a probabilistic one; that is, the most likely universe is not an empty one but a universe of the type we live in that has to be conducive to life (for else, we could not reason about it).
