NJHD 51 - of sciences and knowledges

NJHD 51
Of sciences and knowledges, by which the internal spiritual person is opened.
Those things are called scientifics,
which are in the external or natural person, and its memory,
but not those which are in the internal or spiritual person.
(AC 3019, 3020, 3293, 3309, 4967, 9918, 9922)

The external person is respectively the world,
because the laws of Divine order existing in the world are inscribed therein;
and the internal person is respectively heaven,
because the laws of Divine order existing in heaven are inscribed therein.
(AC 4523, 4524, 5368, 6013, 6057, 9278, 9279, 9283, 9709, 10156, 10472; HH 51-58).

There are scientifics which concern natural things,
scientifics which relate to the civil state and life,
scientifics which relate to the moral state and life,
and scientifics which relate to the spiritual state and life.
(AC 5774, 5934)
But for distinction's sake,
those which relate to the spiritual state and life are called knowledges,
consisting principally of doctrinals.
(AC 9945)

A person ought to be imbued (infused) with sciences and knowledges,
since by these he learns to think,
then to understand what is true and good,
and finally to be wise,
that is to live according to them.
(AC 129, 1450, 1451, 1453, 1548, 1802)

Scientifics are as it were mirrors,
in which the truths and goods of the internal person appear,
and are perceived as in an image.
(AC 5201)

Scientifics, because they are in the light of the world,
are involved and obscure respectively to those things
which are in the light of heaven. . . .
