446. II. THE LOVE OF THE SEX, FROM WHICH FORNICATION IS DERIVED, COMMENCES WHEN A YOUTH BEGINS TO THINK AND ACT FROM HIS OWN UNDERSTANDING, AND HIS VOICE TO BE MASCULINE. This article is adduced to the intent, that the birth of the love of the sex, and thence of fornication, may be known, as taking place when the understanding begins of itself to become rational, or from its own reason to discern and provide such things as are of emolument and use, whereto in such case what has been implanted in the memory from parents and masters, serves as a plane. At that time a change takes place in the mind; it before thought only from things introduced into the memory, by meditating upon and obeying them; it afterwards thinks from reason exercised upon them, and then, under the guidance of the love, it arranges into a new order the things seated in the memory, and in agreement with that order it disposes its own life, and successively thinks more and more according to its own reason, and wills from its own freedom. It is well known that the love of the sex follows the commencement of a man's own understanding, and advances according to its vigor; and this is a proof that that love ascends and descends as the understanding ascends and descends: by ascending we mean into wisdom, and by descending, into insanity; and wisdom consists in restraining the love of the sex, and insanity in allowing it a wide range: if it be allowed to run into fornication, which is the beginning of its activity, it ought to be moderated from principles of honor and morality implanted in the memory and thence in the reason, and afterwards to be implanted in the reason and in the memory. The reason why the voice also begins to be masculine, together with the commencement of a man's own understanding, is, because the understanding thinks, and by thought speaks; which is a proof that the understanding constitutes the man (vir), and also his male principle; consequently, that as his understanding is elevated, so he becomes a man-man (homo vir), and also a male man (masculus vir); see above, n. [432], [433].
447. III. FORNICATION IS OF THE NATURAL MAN, in like manner as the love of the sex, which, if it becomes active before marriage, is called fornication. Every man (homo) is born corporeal, becomes sensual, afterwards natural, and successively rational; and, if in this case he does not stop in his progress, he becomes spiritual. The reason why he thus advances step by step, is, in order that planes may be formed, on which superior principles may rest and find support, as a palace on its foundations: the ultimate plane, with those that are formed upon it, may also be compared to ground, in which, when prepared, noble seeds are sown. As to what specifically regards the love of the sex, it also is first corporeal, for it commences from the flesh: next it becomes sensual, for the five senses receive delight from its common principle; afterwards it becomes natural like the same love with other animals, because it is a vague love of the sex; but as a man was born to become spiritual, it becomes afterwards natural-rational, and from natural-rational spiritual, and lastly spiritual-natural; and in this case, that love made spiritual flows into and acts upon rational love, and through this flows into and acts upon sensual love, and lastly through this flows into and acts upon that love in the body and the flesh; and as this is its ultimate plane, it acts upon it spiritually, and at the same time rationally and sensually; and it flows in and acts thus successively while the man is meditating upon it, but simultaneously while he is in its ultimate. The reason why fornication is of the natural man, is, because it proceeds proximately from the natural love of the sex; and it may become natural-rational, but not spiritual, because the love of the sex cannot become spiritual, until it becomes conjugial; and the love of the sex from natural becomes spiritual, when a man recedes from vague lust, and devotes himself to one of the sex, to whose soul he unites his own.
448. IV. FORNICATION IS LUST, BUT NOT THE LUST OF ADULTERY. The reasons why fornication is lust are, 1. Because it proceeds from the natural man, and in everything which proceeds from the natural man, there is concupiscence and lust; for the natural man is nothing but an abode and receptacle of concupiscences and lust, since all the criminal propensities inherited from the parents reside therein. 2. Because the fornicator has a vague and promiscuous regard to the sex, and does not as yet confine his attention to one of the sex; and so long as he is in this state, he is prompted by lust to do what he does; but in proportion as he confines his attention to one of the sex, and loves to conjoin his life with hers, concupiscence becomes a chaste affection, and lust becomes human love.
449. That the lust of fornication is not the lust of adultery, every one sees clearly from common perception. What law and what judge imputes a like criminality to the fornicator as to the adulterer? The reason why this is seen from common perception is, because fornication is not opposed to conjugial love as adultery is. In fornication conjugial love may lie stored up within, as what is spiritual may lie stored up in what is natural; yea, what is spiritual is also actually disengaged from what is natural; and when the spiritual is disengaged, then the natural encompasses it, as bark does its wood, and a scabbard its sword, and also serves the spiritual as a defence against violence. From these considerations it is evident, that natural love, which is love to the sex, precedes spiritual love which is love to one of the sex; but if fornication comes into effect from the natural love of the sex, it may also be wiped away, provided conjugial love be regarded, desired, and sought, as the chief good. It is altogether otherwise with the libidinous and obscene love of adultery, which we have shewn to be opposite to conjugial love, and destructive thereof, in the [foregoing chapter] concerning the opposition of adulterous and conjugial love: wherefore if a confirmed and determined adulterer for various reasons enters into a conjugial engagement, the above case is inverted, since a natural principle lies concealed within its lascivious and obscene things, and a spiritual appearance covers it externally. From these considerations reason may see, that the lust of limited fornication is, in respect to the lust of adultery, as the first warmth is to the cold of mid-winter in northern countries.
450. V. WITH SOME MEN THE LOVE OF THE SEX CANNOT WITHOUT HURT BE TOTALLY CHECKED FROM GOING FORTH INTO FORNICATION. It is needless to recount the mischiefs which may be caused and produced by too great a check of the love of the sex, with such persons as labor under a superabundant venereal heat; from this source are to be traced the origins of certain diseases of the body and distempers of the mind, not to mention unknown evils, which are not to be named; it is otherwise with those whose love of the sex is so scanty that they can resist the sallies of its lust; also with those who are at liberty to introduce themselves into a legitimate partnership of the bed while they are young, without doing injury to their worldly fortunes, thus under the first favorable impressions. As this is the case in heaven with infants, when they have grown up to conjugial age, therefore it is unknown there what fornication is: but the case is different in the world where matrimonial engagements cannot be contracted till the season of youth is past, and where, during that season, the generality live within forms of government, where a length of time is required to perform duties, and to acquire the property necessary to support a house and family, and then first a suitable wife is to be courted.
[Footnote: This, like some other of the author's remarks, is not so applicable to English laws and customs as to those of several of the continental states, especially Germany, where men are not allowed to marry till they have attained a certain age, or can show that they possess the means of supporting a wife and family.]
