For (setting aside this supposition of the futurition of the thing and of the prevision or of the resolution of God, a supposition which already lays it down as a fact that the thing will happen, and in accordance with which one must say, 'Unumquodque, quando est, oportet esse, aut unumquodque, siquidem erit, oportet futurum esse'), the event has nothing in it to render it necessary and to suggest that no other thing might have happened in its stead.
