  In an interesting discussion of foreknowledge, he considers the argument that since it is necessary that whatever God foresees will come about will come about, because otherwise God could be deceived or mistaken, then since God foresees each thing that will come about, it is necessary that it will come about. William replies that the proposition “It is necessary that whatever God foresees will come about will come about” has two interpretations, “because the necessity can refer to individuals or to the whole” (OO I, 778b; Teske 2007, 99). The argument for the necessity of all events equivocates between these two readings and is therefore invalid. William notes that the distinction he makes is close to the distinction between a divided and composite sense, but he is critical of those who instead distinguish an ambiguity between a de re (about the thing) and de dicto (about what is said) reading.
