5. And so of duration.
As, by the power we find in ourselves of repeating, as often as we will, any idea of space,
we get the idea of immensity; so, by being able to repeat the idea of any length of duration we have in our minds,
with all the endless addition of number, we come by the idea of eternity. For we find in ourselves, we can no more
come to an end of such repeated ideas than we can come to the end of number; which every one perceives he
cannot. But here again it is another question, quite different from our having an idea of eternity, to know whether
there were any real being, whose duration has been eternal. And as to this, I say, he that considers something now
existing, must necessarily come to Something eternal. But having spoke of this in another place, I shall say here
no more of it, but proceed on to some other considerations of our idea of infinity.
