 A proud physicist is naturally tempted to announce these insights through the bullhorn of metaphysics. But philosophers interested in the logic of questions will draw attention to the role of emphasis in framing requests for explanations. ‘Why did Eve eat the apple?’, ‘Why did Eve eat the apple?’, and ‘Why did Eve eat the apple?’ are different questions because they specify different contrast classes (van Fraassen 1980, 127–130). Philosophers read ‘Why is there something rather than nothing?’ tenselessly as in ‘Why is π an irrational number?’. The philosophers also read ‘something’ as a quantifier ranging over any concrete entity. The quantum vacuum is a concrete entity (in the sense described in sections 4 and 7) and so is in the philosopher’s domain of discourse. But for rhetorical effect, physicists anachronistically back-date their domain of discourse to the things of nineteenth century physics. Thus the physicists wind up addressing ‘Why is there some thing rather than nothing?’.
