387. II. THAT THESE TWO UNIVERSAL SPHERES MAKE ONE WITH THE SPHERE OF CONJUGIAL LOVE AND THE SPHERE OF THE LOVE OF INFANTS. That the sphere of conjugial makes one with the sphere of procreating is evident, procreation being the end and conjugial love the mediate cause whereby that end is effected; and in the effecting and the effects, the end and the cause act as one because they act together. That the sphere of the love of infants makes one with the sphere of protecting what is procreated is also evident; for it is an end proceeding from the prior end which was procreation, the love of infants being the mediate cause whereby that end is effected. Ends progress in a series, one after another, and in their progression, an ultimate end becomes a first end, and so onwards up to the terminus where they stop or cease. But of this, more may be seen in the exposition of article XII.
