Secondly, if nothing had been created, there would have been no extrinsic terms capable of extending successive duration; but, since God would have remained in his eternity, there would have remained the reality in which all extrinsic terms of duration have their virtual being; and thus there would have remained, eminently and without formal succession, in God himself the duration of all the beings possible outside of God. For he would certainly not have ceased to exist in all the instants of duration in which creatures have existed; the only change would have been this: that those instants, owing to a total absence of creatures, would have lacked their formal denomination of _instants_, and their formal successivity. Hence, if nothing had been created, there would have remained infinite real duration without succession, simply because the virtuality of God’s eternity would have remained in all its perfection. It is therefore this virtuality that formally constitutes standing duration. From this the reader will easily understand that in the concept of standing duration two notions are involved, viz.: that of _eternity_, as expressing the standing, and that of its _virtuality_, as connoting virtual extent. In fact, God’s eternity, absolutely considered, is simply the actuality of God’s substance, and, as such, does not connote duration; for God’s substance is not said _to endure_, but simply _to be_. The formal reason of duration is derived from the extrinsic terminability of God’s eternity; for the word “duration” conveys the idea of continuation, and continuation implies succession. Hence it is on account of its extrinsic terminability to successive terms of duration that God’s eternity is conceived as equivalent to infinite succession; for what virtually contains in itself all possible terms and intervals of succession virtually contains in itself all succession, and can co exist, without intrinsic change, with all the changes of contingent duration. Balmes, after defining succession as the existence of such things as exclude one another, very properly remarks: “If there were a being which neither excluded any other being nor were excluded by any of them, that being would co-exist with all beings. Now, one such being exists, viz.: God, and God alone. Hence theologians do but express a great and profound truth when they say (though not all, perhaps, fully understand what they say) that God is present to all times; that to him there is no succession, no _before_ or _after_; that to him everything is present, is _Now_.”[11] We conclude that standing duration is infinite, all-simultaneous, independent of all contingent things, indivisible, immovable, formally simple and unextended, but equivalent to infinite intervals of successive duration, and virtually extending through infinite lengths. This duration is absolute.
