 The view that there is an operation of negation, or conjunction, or disjunction on facts is compatible with the claim that some facts are complex. For on a natural view, a conjunctive fact is literally composed by the facts of which it is a conjunction—and similarly for negation and disjunction. (Notice that admitting any two of the Boolean operations would then force one to accept that there are several ways in which the very same facts can combine in order to make up a fact.) Acceptance of some Boolean operations on facts is compatible with taking facts to be complex, but it does not entail it: one may accept, e.g., that a given fact is the conjunction of other facts, and at the same time believe, say, that its depends for its identity on them without having them as parts.
