AC 1598, 1600 - Memory-knowledges for beautiful use or deformed evil?

AC 1598, 1600

"Lot dwelt in the cities of the plain,
and pitched his tent as far as Sodom,"
(Genesis 13:12)

signifies the external man when not united to the internal;
and by these things is signified memory-knowledges
from the affections of evil, or from cupidities.
For there was described the beauty
of the external man when united to the internal;
but here, its deformity when not united;
and still more is this deformity described
in the verse that follows, where it is said,
"and the men of Sodom
were wicked and sinners against Jehovah exceedingly." 
What the deformity of the external man is
when separated from the internal,
may be seen by everyone from what has been said
concerning the love of self and its cupidities,
which are what principally disunite.
As great as is the beauty of the external man
when united to the internal,
so great is its deformity when disunited.
For considered in itself
the external man is as nothing else
than a servant to the internal;
it is a kind of instrumentality by means of which
ends may become uses,
and uses be presented in effect,
so that there may thus be a perfection of all things.
The contrary takes place when the external man
separates itself from the internal,
and desires to be of service to itself alone;
and still more is this the case
when it desires to rule over the internal man,
which is principally the case
from the love of self and its cupidities,
as has been shown.

Memory-knowledges are said
to extend themselves to cupidities,
when they are learned with no other end
than that the man may become great;
not that they may serve him for use,
that he may thereby become good.
All memory-knowledges are for the end
that a man may become rational, and thus wise;
and that thereby he may serve the internal man.
