  There is no upper bound on the “size” of a molecular fact and no restriction on which atomic facts can form a conjunction; for  any atomic facts at all, there is a molecular fact whose conjuncts  are exactly those facts. As a first cut, then, we can spell out  Wittgenstein's characterization of the (actual) world as the totality of facts by defining the world to be the largest molecular fact, the  molecular fact that includes all of the atomic   facts.[39]
