404. (15) Conjugial love is conjoined with a love of little children in parents by spiritual motivations and consequent natural ones. The spiritual motivations are to bring about a proliferation of the human race and from it an enlargement of the angelic heaven, and so to give birth to those who will become angels, serving the Lord in the performance of useful services in heaven and, by association with people, also on earth. (For every person has angels associated with him by the Lord, with whom there is such a conjunction that, if they were taken away, the person would in an instant collapse.) The natural motivations causing a conjunction of these two loves are to give birth to those who may contribute useful services in human societies, and to bring about their incorporation into those societies as members. That these spiritual and natural motivations are connected with a love of little children and conjugial love is something married partners themselves also think and sometimes declare, saying that they have enriched heaven with as many angels as they have descendants, and that they have embellished society with as many contributors as they have children.
