The Creator of the universe divided the whole creation into genera, and each genus into species, and each species into varieties, and these again similarly, and so on. His aim was to bring into existence an image of the infinite in the perpetual variation of characters. So the Creator of the universe divided up kinds of good and their truths, and likewise evils and their falsities, after these had arisen. All things without exception in the spiritual world were divided by the Creator into genera, species and varieties, and all things good and true were assigned to heaven, and all things evil and false to hell, one set being arranged as diametrically opposite to the other; these facts can be established from what was revealed in the work on HEAVEN AND HELL, published in London in 1758. So too in the natural world He divided and divides the forms of good and truth and evil and falsity that people have, and so people themselves; this can be known from their fate after death, heaven for the good, hell for the wicked. Now since all things to do with good, and all to do with evil, are divided into genera, species and so on, therefore marriages are so divided, and so likewise are its opposites, the kinds of adultery.
