need not be at the pains of demonstrating that, whatsoever be the order of the causal sequence, the occurrence of things foreseen is necessary, even though the foreknowledge of future events does not in itself impose upon them the necessity of their occurrence. For example, if a man be seated, the supposition of his being seated is necessarily true; and, conversely, if the supposition of his being seated is true, because he is really seated, he must necessarily be sitting. So, in either case, there is some necessity involved—in this latter case, the necessity of the fact; in the former, of the truth of the statement. But in both cases the sitter is not therefore seated because the opinion is true, but rather the opinion is true because antecedently he was sitting as a matter of fact. Thus, though the cause of the truth of the opinion comes from the other side,1 yet there is a necessity on both sides alike. We can obviously reason similarly in the case of providence and the future. Even if future events are foreseen because they are about to happen, and do not come to pass because they are foreseen, still, all the same, there is a necessity, both that they should be foreseen by God as about to come to pass, and that when they are foreseen they should happen, and this is sufficient for the destruction of free will. However, it is preposterous to speak of the occurrence of events in time as the cause of eternal foreknowledge. And yet if we believe that God foresees future events because they are about to come to pass, what is it but to think that the occurrence of events is the cause of His supreme providence? Further, just as when I know that anything is, that thing necessarily is, so when I know that anything will be, it will necessarily be. It follows, then, that things foreknown come to pass inevitably.
'Lastly, to think of a thing as being in any way other than what it is, is not only not knowledge, but it is false opinion widely different from the truth of knowledge. Consequently, if anything is about to be, and yet its occurrence is not certain and necessary, how can anyone foreknow that it will occur? For just as knowledge itself is free from all admixture of falsity, so any conception drawn from knowledge cannot be other than as
