HH 464 - reasoning is not rationality

HH 464 [5-6]
. . . those who were opposed to the truths of the church,
and who thought from mere knowledges
and confirmed themselves thereby in falsities,
did not cultivate their rational faculty,
but cultivated only an ability to reason,
which in the world is believed to be rationality.
But this ability is wholly different from rationality;
it is an ability to prove any thing it pleases,
and from preconceived principles and from fallacies
to see falsities and not truths.
Such persons can never be brought to acknowledge truths,
since truths cannot be seen from falsities;
but falsities may be seen from truths.

The rational faculty of a person is like a garden or shrubbery,
or like fresh ground;
the memory is the soil,
truths known and knowledges are the seeds,
the light and heat of heaven cause them to grow.
Without light and heat
there is no germination;
so is it with the mind
when the light of heaven,
which is Divine truth,
and the heat of heaven,
which is Divine love,
are not admitted;
rationality is solely from these.
