ABSTRACT
Facts are constitutive properties of the world. Fred Sommers has pointed out that L. Wittgenstein, for one, saw the correlation between the proposition/fact distinction and the belief/knowledge distinction. One of the Wittgenstein-supported claims is that propositions are among the proper objects of belief; they are quite distinct from facts, which are the proper objects of knowledge. There is a correspondence between a speaker's beliefs and statements. Taking belief to be primarily a relation between a believer and a proposition is standard procedure. Belief is fundamentally a "propositional attitude". One way of looking at the beliefs is as dispositions to assent to the truth of certain propositions. Philosophers have generally failed to appreciate de mondo belief because they have tended to overlook the fact that the intercourse with any individual must always involve as well the ontological environment, the domain, of that individual.
