83. There are both internal and external origins of conjugial love, and several of each; nevertheless there is but one inmost or universal origin of all. That this origin is the marriage of good and truth, shall be demonstrated in what now follows. The reason why no one heretofore has deduced the origin of that love from this ground, is, because it has never yet been discovered that there is any union between good and truth; and the reason why this discovery has not been made, is, because good does not appear in the light of the understanding, as truth does, and hence the knowledge of it conceals itself and evades every inquiry: and as from this circumstance good is as it were unknown, it was impossible for any one to conjecture that any marriage subsisted between it and truth: yea, before the rational natural sight, good appears so different from truth, that no conjunction between them can be supposed. That this is the case, may be seen from common discourse whenever they are mentioned; as when it is said, "This is good," truth is not at all thought of; and when it is said, "This is true," neither is good at all thought of; therefore at this day it is believed by many, that truth is one thing and good another; and by many also, that a man is intelligent and wise, and thereby a man (_homo_), according to the truths which he thinks, speaks, writes, and believes, and not at the same time according to goods. That nevertheless there is no good without truth, nor any truth without good, consequently that there is an eternal marriage between them; also that this marriage is the origin of conjugial love, shall now be shewn and explained in the following order: I. _Good and truth are the universals of creation, and thence are in all created things; but they are in created subjects according to the form of each._ II. _There is neither solitary good nor solitary truth, but in all cases they are conjoined._ III. _There is the truth of good, and from this the good of truth; or truth grounded in good, and good grounded in that truth: and in those two principles is implanted from creation an inclination to join themselves together into a one._ IV. _In the subjects of the animal kingdom, the truth of good, or truth grounded in good, is male (or masculine); and the good of that truth, or good grounded in that truth, is female (or feminine)._ V. _From the influx of the marriage of good and truth from the Lord, the love of the sex and conjugial love are derived._ VI. _The love of the sex belongs to the external or natural man, and hence it is common to every animal._ VII. _But conjugial love belongs to the internal or spiritual man; and hence this love is peculiar to man._ VIII. _With man conjugial love is in the love of the sex as a gem in its matrix._ IX. _The love of the sex with man is not the origin of conjugial love, but its first rudiment; thus it is like an external natural principle, in which an internal spiritual principle is implanted._ X.
