404. XV. THAT WITH PARENTS, CONJUGIAL LOVE IS CONJOINED WITH THE LOVE OF INFANTS BY SPIRITUAL CAUSES, AND BY NATURAL CAUSES THEREFROM. The spiritual causes are: That the human race may be multiplied and the angelic heaven therefrom enlarged; thus, that those may be born who will become angels, serving the Lord in the performance of uses in heaven and, by consociation with men, also on earth; for angels are associated by the Lord with every man, and such is the conjunction with them that were they taken away the man would die in a moment. The natural causes of the conjunction of these two loves are: That those may be born who will perform uses in human societies, and will be incorporated therein as members. That the latter are the natural and the former the spiritual causes of the love of infants and of conjugial love, is also the thought of married partners themselves. Moreover, they sometimes declare it, saying that they have enriched heaven with as many angels as they have descendants, and have put their mark upon society With as many servants as they have children.
