AE 570, 572, 573 - The Source of Reasoning; AE 575 - Visions

 AE 570

. . . the sensual person only reasons
from such things as he sees in the world with his eyes,
while the things that are within and above these
he declares cannot be,
since he does not see them;
this is why the things that belong to heaven and the church,
because they are above his thoughts,
he either denies or does not believe,
but ascribes all things to nature.

AE 572

. . . it is by means of truths from good
that the understanding is opened,
not by means of truths without good;
for a person thinks truth
so far as he lives in the good of love and charity.

AE 573

. . . since reasonings from falsities
are from the understanding perverted and destroyed,
for truths constitute the understanding,
but falsities destroy it.

AE 575 [2]

Visions, which and from which
a person or the spirit of a person sees,
are of a twofold kind;
there are real visions and visions that are not real;
real visions are visions of such things
as really appear in the spiritual world,
corresponding altogether with
the thoughts and affections of angels,
consequently they are real correspondences.
Such were the visions that the prophets had
who prophesied truths;
such also were the visions that appeared to John,
and that are described throughout Revelation.
But visions that are not real
have the same appearance in the external form
as real visions, but not in the internal form;
they are produced by spirits by means of fantasies.
Such visions those prophets had
who prophesied vain things or lies.
All such visions, because they are not real are fallacies,
and thus they also signify fallacies.
