by those who called themselves learned; for from themselves they are unable to see any thing, whether it be true or not, and consequently are unable to see any thing rationally when listening to others. [5] I have also talked with some who had written much in the world on scientific subjects of every kind, and had thereby acquired a worldwide reputation for learning. Some of these, indeed, had the ability to reason about truths, whether they are true or not; and some, when they had turned to those who were in the light of truth, had some comprehension that truths are true, but still had no wish to comprehend them, and therefore when they were in their own falsities, and thus in themselves, denied them. Some had no more wisdom than the unlearned common people. Thus each differed from the other according as he had cultivated his rational faculty by means of the knowledges he had written about or collated. But 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. [6] The rational faculty of man 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. It is a great grief to the angels that learned men for the most part ascribe all things to nature, and have thereby so closed up the interiors of their minds as to be unable to see any thing of truth from the light of truth, which is the light of heaven. In consequence of this such in the other life are deprived of their ability to reason that they may not disseminate falsities among the simple good and lead them astray; and are sent away into desert places.
