We must not be surprised to find that even the highest works of God come to an end. Everything with an end, beginning, and origin, has the mark of its circumscribed nature in itself. The duration of a universe has, by the excellence of its construction, a permanence in itself, which, according to our ideas, comes near to an endless duration. Perhaps thousands, perhaps millions of centuries will not bring it to an end; but while the perishableness which adheres to the evanescent natures is always working for their destruction, so eternity contains within itself all possible periods, so as to bring at last by a gradual decay the moment of its departure.—Kant.
