The subject here treated of is the doctrine of faith, concerning which the Lord thought in His childhood, namely, whether it was allowable to enter into it by means of rational things, and thus form for one's self ideas concerning it. His so thinking came from His love and consideration for the human race, who are such as not to believe what they do not comprehend in a rational manner.

But He perceived from the Divine that this ought not to be done; and He therefore revealed the doctrine to Himself from the Divine, and thereby at the same time all things in the universe that are subordinate, namely, all things of the rational and of the natural.

[2] How the case is with the doctrinal things of faith among men has been stated above (n. 2568), namely, that there are two principles from which they think, a negative and an affirmative; and that those think from the negative principle, who believe nothing unless they are convinced by what is of reason and memory-knowledge; nay, by what is of sense; but those think from the affirmative who believe that things are true because the Lord has said so in the Word, thus who have faith in the Lord.

They who are in the negative in regard to a thing being true because it is in the Word, say at heart that they will believe when they are persuaded by things rational and memory-knowledges. But the fact is that they never believe; and indeed they would not believe if they were to be convinced by the bodily senses of sight, hearing, and touch; for they would always form new reasonings against such things, and would thus end by completely extinguishing all faith, and at the same time turning the light of the rational into darkness, because into falsities.

But those who are in the affirmative, that is, who believe that things are true because the Lord has said so, are continually being confirmed, and their ideas enlightened and strengthened, by what is of reason and memory-knowledge, and even by what is of sense; for man has light from no other source than by means of the things of reason and memory, and such is the way with everyone. With these the doctrine thus "living lives;" and of them it is said, that they "are healed," and "bring forth;" whereas with those who are in the negative the doctrine "dying dies;" and it is said of them that "the womb closing is closed."

All this shows what it is to enter into the doctrine of faith by means of rational things, and what to enter into rational things by means of the doctrine of faith; but let this be illustrated by examples.

[3] It is from the doctrine of the Word, that the first and principal thing of doctrine is love to the Lord and charity toward the neighbor. They who are in the affirmative in regard to this can enter into whatever things of reason and of memory, and even of sense, they please, everyone according to his gift, his knowledge, and his experience. Nay, the more they enter in, the more they are confirmed; for universal nature is full of confirmation.

But they who deny this first and principal thing of doctrine, and who desire to be first convinced of anything true by means of the things of reason and memory, never suffer themselves to be convinced, because at heart they deny, and all the time take their stand in favor of some other principle which they believe to be essential; and finally, by confirmations of their principle they so blind themselves that they cannot even know what love to the Lord and love to the neighbor are.

And as they confirm themselves in what is contrary, they at length confirm themselves in the notion that no other love is possible that has any delight in it except the love of self and of the world; and this to such a degree (if not in doctrine, yet in life) that they embrace infernal love in place of heavenly love.

But with those who are not in the negative nor as yet in the affirmative, but are in doubt before they deny or affirm, the case is as above stated (n. 2568), namely that they who incline to a life of evil fall into the negative, but they who incline to a life of good are brought into the affirmative.

[4] Take another example: It is among the primary things of the doctrine of faith that all good is from the Lord, and all evil from man, that is, from one's self. They who are in the affirmative that it is so, can confirm themselves by many things of reason and of memory-knowledge, such as that no good can possibly flow in except from good itself, that is, from the Fountain of Good, thus from the Lord; and that the beginning or principle of good can be from no other source; finding illustration in all things that are truly good, in themselves, in others, in the community, and also in the created universe.

But they who are in the negative confirm themselves in what is contrary by everything they think of, insomuch that at last they do not know what good is; and dispute among themselves as to what is the highest good, being deeply ignorant of the fact that it is the celestial and spiritual good from the Lord, by which all lower good is made alive, and that the delight therefrom is truly delight. Some also think that unless good is from themselves, it cannot possibly come from any other source.

[5] Take as another example the truth that they who are in love to the Lord and charity toward the neighbor can receive the truths of doctrine and have faith in the Word, but not they who are in the life of the love of self and the world; or what is the same, that they who are in good can believe, but not they who are in evil. They who are in the affirmative can confirm this by numberless things of reason and memory. From reason they can confirm it on the ground that truth and good agree, but not truth and evil; and that as all falsity is in evil, so it is from evil; and that if any who are in evil nevertheless have truth, it is on the lips, and not in the heart; and from their memory-knowledge they can confirm by many things that truths shun evils, and that evils spew out truths.

But they who are in the negative confirm themselves by alleging that everyone, of whatever character, is able to believe just as well as others, even though he lives in continual hatred, in the delights of revenge, and in deceit; and this even while they themselves altogether reject from their doctrine the good of life, after the rejection of which they do not believe anything.

[6] That it may be still more manifest how the case herein is, let us take this example: They who are in the affirmative that the Word has been so written as to possess an internal sense which does not appear in the letter, can confirm themselves therein by many rational considerations;

as that by the Word man has connection with heaven; that there are correspondences of natural things with spiritual, in which the spiritual are not seen; that the ideas of interior thought are altogether different from the material ideas which fall into the words of language; that man, being born for both lives, can, while in the world, be also in heaven, by means of the Word which is for both worlds; that with some persons a certain Divine light flows into the things of the understanding, and also into the affections, when the Word is read; that it is of necessity that there should be something written that has come down from heaven, and that therefore the Word cannot be such in its origin as it is in the letter; and that it can be holy only from a certain holiness that it has within it.

He can also confirm himself by means of memory-knowledges;

as that men were formerly in representatives, and that the writings of the Ancient Church were of this nature; also that the writings of many among the Gentiles had this origin; and that it is on this account that in the churches such a style has been revered as holy, and among the Gentiles as learned, as examples of which the books of many authors might be mentioned.

But they who are in the negative, if they do not deny all these things, still do not believe them, and persuade themselves that the Word is such as it is in the letter, appearing indeed worldly, while yet being spiritual (as to where the spiritual is hidden within it they care little, but for manifold reasons are willing to let it be so), and this they can confirm by many things.

[7] In order to present the subject to the apprehension of the simple, take as an example the following matter of knowledge. They who are in the affirmative that sight is not of the eye, but of the spirit, which sees the things that are in the world through the eye as an organ of its body, can confirm themselves by many things;

as from our hearing things said by others; in that they refer themselves to a certain interior sight, into which they are changed; which would be impossible unless there were an interior sight; also that whatever is thought of is seen by an interior sight, by some more clearly, by others more obscurely; and again, that things we imagine present themselves not unlike objects of sight; and also that unless it were the spirit within the body that saw the objects which fall within the ken of the eye as the organ of sight, the spirit could see nothing in the other life, when yet it cannot but be that it will see innumerable and amazing things that cannot possibly be seen with the bodily eye.

Then again we may reflect that in dreams, especially those of the prophets, many things have been seen although not with the eyes. And finally, should anyone be skilled in philosophy, he may confirm himself by considering that outer things cannot enter into inner things, just as compounds cannot into simples; and therefore that things of the body cannot enter into those of the spirit, but only the reverse; not to mention a host of other proofs, until at last the man is persuaded that the spirit has sight, and not the eye, except from the spirit.

But they who are in the negative call every consideration of this kind either a matter of nature or one of fancy, and when they are told that a spirit possesses and enjoys much more perfect sight than a man in the body, they ridicule the idea, and reject it as an idle tale, believing that if deprived of the sight of the bodily eye they would live in the dark; although the very opposite is the truth, for they are then in the light.

[8] From these examples we may see what it is to enter into the things of reason and memory-knowledge from truths, and what it is to enter into truths from the things of reason and memory-knowledge; and that the former is according to order, but the latter contrary to order; and that when we do that which is according to order we are enlightened; but when we do that which is contrary to order, we are made blind.

All of which shows of how great concern it is that truths should be known and believed; for man is enlightened by truths, but is made blind by falsities. By truths there is opened to the rational an immense and almost unbounded field; but by falsities comparatively none at all, although this does not appear to be so. It is because the angels are in truths that they enjoy wisdom so great; for truth is the very light of heaven.

[9] They who have blinded themselves by not being willing to believe anything which they do not apprehend by the senses, until at length they have come to believe nothing, were in old times called "serpents of the tree of knowledge;" for such reasoned much from sensuous things and their fallacies, which easily fall into man's apprehension and belief, and thereby they seduced many (see n. 195, 196). In the other life such are readily distinguished from other spirits by the fact that in regard to all things of faith they reason whether it be so; and if they are shown a thousand and a thousand times that it is so, still they advance negative doubts against every proof that is offered; and this they would go on doing to all eternity.

So blind are they on this account that they have not common sense, that is, they cannot comprehend what good and truth are; and yet every one of them thinks himself wiser than all in the universe; making wisdom to consist in being able to invalidate what is Divine, and deduce it from what is natural. Many who in this world have been esteemed wise, are preeminently of this character; for the more anyone is endowed with talent and knowledge, and is in the negative, the more insane he is, beyond all others; whereas the more anyone is endowed with talent and knowledge, and is in the affirmative, the wiser he is able to be.

It is by no means denied man to cultivate the rational faculty by means of memory-knowledges; but that which is forbidden is to harden ourselves against the truths of faith which belong to the Word.
