OF the bliss of Paradise, of Paradise itself, and of the life of our first parents there, and of their sin and punishment, many have thought much, spoken much, written much. We ourselves, too, have spoken of these things in the foregoing books, and have written either what we read in the Holy Scriptures, or what we could reasonably deduce from them. And were we to enter into a more detailed investigation of these matters, an endless number of endless questions would arise, which would involve us in a larger work than the present occasion admits. We cannot be expected to find room for replying to every question that may be started by unoccupied and captious men, who are ever more ready to ask questions than capable of understanding the answer. Yet I trust we have already done justice to these great and difficult questions regarding the beginning of the world, or of the soul, or of the human race itself. This race we have distributed into two parts, the one consisting of those who live according to man, the other of those who live according to God. And these we also mystically call the two cities, or the two communities of men, of which the one is predestined to reign eternally with God, and the other to suffer eternal punishment with the devil. This, however, is their end, and of it we are to speak afterwards. At present, as we have said enough about their origin, whether among the angels, whose numbers we know not, or in the two first human beings, it seems suitable to attempt an account of their career, from the time when our two first parents began to propagate the race until all human generation shall cease. For this whole time or world-age, in which the dying give place and those who are born succeed, is the career of these two cities concerning which we treat.
