After a tacit agreement between the parties, it appears as if conjugial love was made friendship; but the difference between conjugial and servile friendship in marriages, is like that between light and shade, between a living fire and an _ignis fatuus_, yea, like that between a well-conditioned man and one consisting only of bone and skin. 249. XIII. OF EXTERNAL CAUSES OF COLD THE FOURTH IS, A WANT OF DETERMINATION TO ANY EMPLOYMENT OR BUSINESS, WHENCE COMES WANDERING PASSION. Man (_homo_) was created for use, because use is the continent of good and truth, from the marriage of which proceeds creation, and also conjugial love, as was shewn above. By employment and business we mean every application to uses; while therefore a man is in any employment and business, or in any use, in such case his mind is limited and circumscribed as in a circle, within which it is successively arranged into a form truly human, from which as from a house he sees various concupiscences out of himself, and by sound reason within exterminates them; consequently also he exterminates the wild insanities of adulterous lust; hence it is that conjugial heat remains better and longer with such than with others. The reverse happens with those who give themselves up to sloth and ease; in such case the mind is unlimited and undetermined, and hence the man (_homo_) admits into the whole of it everything vain and ludicrous which flows in from the world and the body, and leads to the love thereof; that in this case conjugial love also is driven into banishment, is evident; for in consequence of sloth and ease the mind grows stupid and the body torpid, and the whole man becomes insensible to every vital love, especially to conjugial love, from which as from a fountain issue the activities and alacrities of life. Conjugial cold with such is different from what it is with others; it is indeed the privation of conjugial love, but arising from defect.
