AC 1468 - wife, husband, man; AC 1472 - memory-knowledges and use

AC 1468

A "wife," in the internal sense of the Word,
signifies nothing else than truth conjoined with good;
for the conjunction of truth with good
is circumstanced precisely as is a marriage.
In the Word, when a "husband" is mentioned,
the husband signifies good,
and the wife signifies truth;
but when he is not called the husband, but the "man,"
then he signifies truth,
and the wife signifies good:
this is the constant usage in the Word . . ..

AC 1472

Anyone can see, if he pays attention,
that in itself the memory-knowledge of knowledges
is nothing but a means whereby a man may become rational,
and from there spiritual,
and at last celestial;
and that by means of the knowledges his external man
may be adjoined to his internal;
and when this is done,
he is in the use itself. 

The internal man regards nothing but the use.
For the sake of this end also,
the Lord insinuates the delight that childhood and youth
perceives in memory-knowledges.
But when a man begins to make his delight
consist in memory-knowledge alone,
it is a bodily cupidity which carries him away,
and in proportion as he is thus carried away
(that is, makes his delight
consist in mere memory-knowledge),
in the same proportion
he removes himself from what is celestial,
and in the same proportion
do the memory-knowledges
close themselves toward the Lord,
and become material.
But in proportion as the memory-knowledges
are learned with the end of use,
as for the sake of human society,
for the sake of the Lord's church on earth,
for the sake of the Lord's kingdom in the heavens,
and still more for the Lord's own sake,-
the more are they opened toward Him.
