|Non enim omne ens entitatis suae causam habet nec omnis quaestio de esse habet causam. Si enim quaeratur quare magis est aliquid in rerum natura quam nihil, in rebus causatis loquendo, contingit respondere quia est aliquod Primum Movens immobile et Prima Causa intransmutabilis. Si vero quaeratur de tota universitate entium quare magis est in eis aliquid quam nihil, non contingit dare causam, quia idem est quaerere hoc et quaerere quare magis est Deus quam non est, et hoc non habet causam. Unde non omnis quaestio habet causam nec etiam omne ens.||For not every being has a cause of its being, nor does every question about being have a cause. For if it is asked why there is something in the natural world rather than nothing, speaking about the world of created things, it can be replied that there is a First immoveable Mover, and a first unchangeable cause. But if it is asked about the whole universe of beings why there is something there rather than nothing, it is not possible to give a cause, for it's the same to ask this as to ask why there is a God or not, and this does not have a cause. Hence not every question has a cause, nor even every being.|
*According to Norman Malcolm, Wittgenstein said that he sometimes had a certain experience which could best be described by saying that "when I have it, I wonder at the existence of the world. I am then inclined to use such phrases as 'How extraordinary that anything should exist!'"
