3679. And Esau saw that Isaac blessed Jacob. That this signifies the thought of natural good concerning conjunction through the good of truth which is “Jacob,” is evident from the signification of “seeing,” as being to think; for thinking is nothing else than seeing inwardly, or internal sight; and from the representation of Esau, as being the good of the natural (see n. 3300, 3302, 3322, 3494, 3504, 3576, 3599); from the signification of being “blessed,” as being conjunction (n. 3504, 3514, 3530, 3565, 3584); from the representation of Isaac, as being the Lord’s Divine rational as to Divine good (treated of above); and from the representation of Jacob, as being the good of truth (n. 3669, 3677). From all this it is evident that by “Esau saw that Isaac blessed Jacob,” is signified the thought of natural good concerning conjunction through the good of truth.

[2] What is meant by the thought of natural good concerning conjunction through the good of truth cannot be fully explained to the apprehension, but yet must be briefly explained. The thought of natural good is the thought of the rational or internal man within the natural or external man, and indeed from the good of the latter; for it is the rational or internal man which thinks, and not the natural or external man; the former, or internal man, is in the light of heaven, in which light there is intelligence and wisdom from the the Lord, (n. 3195, 3339, 3636, 3643); but the external man is in the light of the world, in which there is no intelligence, and not even life; and therefore unless the internal man were to think within the external, it would not be possible to think at all. And yet thought appears to man to be in his external man, inasmuch as he thinks from those things which have entered in by the senses and are of the world.

[3] The case is the same as with the sight of the eye. The sensuous man supposes that the eye sees of itself, when yet the eye is merely an organ of the body by which the internal man sees those things which are out of the body, or which are in the world. It is also the same as with speech. The sensuous man would suppose that the mouth and tongue speak of themselves; and they who think somewhat more deeply, that the larynx and interior organs speak by breath from the lungs; when yet it is the thought which speaks by means of these organs, for speech is nothing but thought speaking. There are many such fallacies of the senses. The case is the same in regard to all apparent life in the external man in that it is the life of the internal man therein as in its material and corporeal organ.

[4] With respect to thought, the case is this: So long as man lives in the body he thinks from the rational in the natural, but with a difference accordingly as the natural corresponds to the rational, or does not so correspond. When the natural corresponds, the man is rational, and thinks spiritually; but when the natural does not correspond, the man is not rational, nor can he think spiritually; for with the man whose natural corresponds to his rational the communication is opened, so that the light of heaven from the Lord can flow in through the rational into the natural, and enlighten it with intelligence and wisdom; hence the man becomes rational and thinks spiritually. But with the man whose natural does not correspond to the rational the communication is closed, and there only flows in somewhat of light in general round about, and through chinks through the rational into the natural; and the result is that the man is not rational, and does not think spiritually; for a man thinks according to the influx of the light of heaven that he enjoys. This shows that every man thinks according to the state of correspondence in respect to good and truth of the natural with the rational.

[5] But spirits and angels do not think in the same way as man; their thought is indeed also terminated in a natural, for they have with them all the natural memory and its affections, but are not allowed to use this memory (see n. 2475-2479); yet although they are not allowed to use it, it nevertheless serves them as a plane, or as a foundation, in order that the ideas of their thought may be terminated therein. Hence it is that the ideas of their thought are more interior, and their speech is not as with man from forms of words, but from forms of actual things; showing that their thought also is such as is the correspondence of their natural with their rational; and that there are spirits who are rational, who think spiritually, and also those who are not rational, who do not think spiritually; and this exactly in accordance with their affections and consequent thoughts of things in the life of the body; that is, with the state of life they had acquired in the world.

[6] From this it may in some measure appear what the thought of natural good is, namely, that it is thought in the good of the natural. According to the idea of spirits that is called the thought of natural good which according to the idea of men is called thought in the good of the natural. In this latter, that is, in the good of the natural, the rational thinks when it has regard to good as the end. Thus the thought of natural good concerning conjunction through the good of truth, is thought in the natural concerning the end, namely, how truth can be conjoined therewith; and this according to Divine order by the common way; which, as has often been said above, is from such things as are external, and thus which are the ultimate or last in order; for all the regeneration of the natural commences from these. These last or ultimate things are the first knowledges, such as are those of infants and children, concerning which see above (n. 3665).

[7] In the beginning the truth of good, which is “Esau,” is not conjoined in the external form with the good of truth, which is “Jacob;” for the good of truth is inverse in respect to the truth of good (n. 3669); but still they are inmostly conjoined, that is, in respect to ends. For the end of the truth which is from good is that truths may be adjoined to it according to order; and this also is the end of the good which is from truth; and inasmuch as the end conjoins, therefore they are conjoined (n. 3562, 3565). The inverse of order is at first only a means that has respect to the end.

3494. And he called Esau his elder son. That this signifies the affection of good of the natural, or the good of life, is evident from the representation of Esau, as being the Divine good of the natural (concerning which see n. 3300, 3302, 3322); and because the good of the natural is that which appears in the affection and life, therefore it is the affection of good of the natural, or the good of life, that is here represented by Esau. The affection of good in the natural, and the derivative good of life, is what is called the “elder son;” but the affection of truth, and the derivative doctrine of truth, is what is called the “younger son.” That the affection of good, and the derivative good of life, is the “elder son,” that is, the firstborn, is evident from the fact that infants are first of all in good, for they are in a state of innocence, and in a state of love toward their parents and nurse, and in a state of mutual charity toward their infant companions; so that good is the firstborn with every man. This good, into which man is thus initiated when an infant, remains; for whatever is imbibed from infancy enters into the life; and because it remains, it becomes the good of life; for if man should be without such good as that which he has derived from infancy, he would not be a man, but would be more of a wild beast than any in the forest. This good does not indeed appear to be present, because all that is imbibed in the infantile age does not appear otherwise than as something natural-as is sufficiently manifest from walking, and from the other motions of the body; from the manners and decorums of civil life; also from speech, and various other things. From this it may be seen that good is the “elder son,” that is, the firstborn, and consequently that truth is the “younger son,” or is born afterwards; for truth is not learned till the infant becomes a child, a youth, and an adult.

[2] Good as well as truth in the natural or external man is a “son,” that is to say, a son of the rational or internal man; for whatever comes forth in the natural or external man flows in from the rational or internal man, and from this also comes forth and is born; that which does not come forth and is not born therefrom is not a living human thing; it would be as you might say something sensuous corporeal without a soul. From this it is that both good and truth are called “sons,” and indeed sons of the rational. And yet it is not the rational which produces and brings forth the natural, but it is an influx through the rational into the natural, which influx is from the Lord. Therefore all infants who are born are His sons, and afterwards when they become wise, insofar as they are still infants, that is, in the innocence of infancy, in the love of infancy toward their parent, now the Lord, and in the mutual charity of infancy toward their infant companions, now their neighbor, so far they are adopted by the Lord as sons.
