559. Verse 10. And they had tails like scorpions, signifies sensual knowledges [scientifica] that are persuasive. This is evident from the signification of "tails," as meaning sensual knowledges [scientifica] (of which presently); and from the signification of "scorpions," as being an infatuating and suffocating persuasiveness (of which see above, n. 544; therefore "tails like scorpions" signify sensual knowledges which are persuasive. "Tails" signify sensual knowledges because the tails that protrude outwardly from animals of the earth are the continuations of the spinal cord, which is called the spinal marrow, and this is a continuation of the brain, and the "brain" in like manner as the "head," signifies intelligence and wisdom, because intelligence and wisdom in their beginnings have their seat there; and as tails are the ultimates of the brain they signify sensual knowledges, since these are the ultimates of intelligence and wisdom.

[2] Sensual knowledges are such knowledges as enter from the world through the five bodily senses, and thence viewed in themselves are more material, corporeal, and worldly than those that are interior. All who are in the love of self and have confirmed themselves against Divine and spiritual things are sensual men, and when they are left to themselves and think in their spirit, they think about Divine and spiritual things from sensual knowledges, and consequently they reject Divine and spiritual things as not to be believed, because they do not see them with their eyes or touch them with their hands; and they apply their knowledges, which they have made sensual and material, to the destruction of these. For example, men who are learned in this kind of knowledge, who are skilled in physics, anatomy, botany, and other branches of human learning, when they see the wonderful things in the animal and vegetable kingdoms say in their hearts that all these things are from nature, and not from the Divine, and this because they believe in nothing that they do not see with their eyes and touch with their hands; for they are unable to elevate their minds upward so as to see these things from the light of heaven, for that light is thick darkness to them; but they detain their minds in earthly things, much the same as the animals of the earth do, with which indeed they compare themselves. In a word, with such all knowledges [scientiae] are made sensual; for such as the man himself is, such are all things of his understanding and will; if the man is spiritual all things become spiritual; if he is merely natural all things become natural and not spiritual; if the man is sensual all things become sensual, and this however learned and erudite he may seem to the world to be. But as every man has the faculty to understand truths and perceive goods, such men are able from that faculty to talk about these things like those who are spiritual-rational, although in respect to their spirit they are sensual; for when such men speak before others they do not speak from the spirit but from the bodily memory.

[3] All this has been said to make known what sensual knowledges are. These are what especially persuade, or are especially persuasive, because they are the ultimates of the understanding; for into these as into its ultimates the understanding closes, and these captivate the common people because they are appearances drawn from such things as they see in the world with their eyes; and so long as the thought clings to these it is impossible to dispose the mind to think interiorly or above them until they are put away; for the interior things of the mind all close into ultimates and rest upon them, as a house upon its foundation; consequently these are especially persuasive, but only with those whose minds cannot be elevated above sensual things; and the mind is elevated above them with those who are in the light of heaven from the Lord, for the light of heaven dissipates them. For this reason spiritual men rarely think from things sensual, for they think from things rational and intellectual; but sensual men, who have confirmed themselves in falsities against Divine and spiritual things, when they are left to themselves think only from sensual things.

[4] That "tails" signify sensual knowledges [scientifica] can be seen from the following passages. In Isaiah:

Jehovah will cut off from Israel head and tail, branch and rush. The old man and the honorable, he is the head; but the prophet, the teacher of lies, he is the tail (Isaiah 9:14, 9:16).

This means that all intelligence and wisdom and all knowledge [scientia] of truth will perish; the "head" signifies intelligence and wisdom, wherefore it is said "the old man and the honorable, he is the head," for the "old man" signifies the understanding of truth, and the "honorable" the wisdom of good; but the "tail" signifies sensual knowledge [scientificum], which is the ultimate of intelligence and wisdom; when this is not joined to spiritual intelligence it becomes false knowledge, or knowledge applied to confirm falsities, which is sensual knowledge, like that of the sensual man who sees nothing from the understanding. This is why "the prophet who teacheth lies" is called the "tail," a "prophet" signifying the doctrine of truth, and thence the knowledge of truth, but here doctrine and the knowledge of falsity, for a "lie" signifies falsity, and the "teacher of a lie" one who teaches falsity by applying knowledges from the sense of the letter of the Word to confirm falsities.

[5] In the same:

Neither shall there be for Egypt any work that may make head or tail, branch or rush (Isaiah 19:15).

"Egypt" signifies knowledge [scientia] both of spiritual and of natural things; "no work for it that may make head or tail" signifies that it has no spiritual things, neither natural things by which spiritual things are confirmed, the "head" signifies here the cognitions of spiritual things which are means of intelligence, and the "tail" natural knowledges [scientifica] which are serviceable to things spiritual for intelligence; "branch and rush" have a similar signification, "branch" being spiritual truth, and "rush" sensual knowledge, which is ultimate truth; for if what is prior and what is posterior, or what is first and what is last, do not make one in man, he has no "head and tail."

[6] In Moses:

Thus Jehovah shall make thee as the head, and not as the tail; and thou shalt be above only, and thou shalt not be beneath, if thou shalt hearken unto the commandments of thy God (Deuteronomy 28:13).

"To make as the head" means to make spiritual and intelligent, and thus to elevate out of the light of the world into the light of heaven; and "to make as the tail" means to make sensual and foolish, so as not to look to heaven but only to the world; therefore it is said "and thou shalt be above only, and thou shalt not be beneath," "to be above" meaning to be elevated by the Lord so as to look to heaven, and "to be beneath" meaning not to be elevated by the Lord, but by self, and man by self looks only to the world. For man's interiors which belong to his thought and affection are elevated to heaven by the Lord when man is in the good of life and thence in the truths of doctrine; but when he is in the evil of life and thence in falsities, his lower things look downward, thus only to his body and to such things as are in the world, and thus to hell. Thus man puts off his truly human nature and puts on a beastly nature, for beasts look downward and to such things only as are met with in the world and upon the earth. Elevation into the light of heaven by the Lord is an actual elevation of man's interiors to the Lord; and a depression or casting down to such things as are below and outside the eyes is an actual depression and casting down of the interiors, and when this takes place, all the thought of the spirit is immersed in the ultimate sensual.

[7] In Moses:

The sojourner who is in the midst of thee shall ascend above thee higher and higher, but thou shalt come down lower and lower. He shall lend to thee, and thou shalt not lend to him; he shall be as the head, and thou shalt be as the tail (Deuteronomy 28:43, 44).

This must have a like meaning; "to be as the head" signifying to be spiritual and intelligent, and "to be as the tail" to be sensual and stupid; therefore it is added "he shall lend to thee, and thou shalt not lend to him," which signifies that he shall teach thee truths, but thou shalt not teach him.

[8] In Isaiah:

Say unto him, Take heed, and be quiet; fear not, neither let thine heart be soft because of the two tails of smoking firebrands, for the glowing anger of Rezin and Syria, and of the son of Remaliah (Isaiah 7:4).

"Rezin and Syria" signify the perverted rational, and "the son of Remaliah," king of Israel, who is also called "Ephraim," signifies the perverted intellectual; it is the intellectual in respect to the Word that is signified by "the king of Israel" and "Ephraim;" and it is the rational in respect to the knowledges [scientiae] that confirm that is signified by "Rezin and Syria," for a man in order to have an understanding of the Word must have a rational, and when these two are perverted they look only downward to the earth, and outward to the world, as sensual men do who are in the falsities of evil; therefore they are called "tails." A "smoking firebrand" signifies the lust of falsity and consequent wrath against the truths and goods of the church.

[9] In Moses:

Jehovah said unto Moses, Put forth thine hand and take hold of the tail of the serpent. And he put forth his hand and took hold of it, and it became a staff in his hand (Exodus 4:4).

That here, too, "tail" means the sensual which is the ultimate of the natural may be seen in the Arcana Coelestia 6951-6955). Because "tails" signify the ultimates of intelligence and wisdom, which are sensual knowledges [scientifica], and because all the processes attending the sacrifices signified Divine celestial and spiritual things, therefore:

It was commanded that they should take away the tail hard by the backbone, and should sacrifice it with the other parts there mentioned (Leviticus 3:9; 8:25; 9:19; Exodus 29:22).

(That the burnt-offerings and sacrifices signified Divine celestial and spiritual things, which are the internals of the church, of which worship consists, see Arcana Coelestia 2180, 2805, 2807, 3830, 3519, 6905, 8936.) Because "tails" signify sensual knowledges [scientifica], and when these knowledges are separated from things interior which are spiritual, and in consequence do not with things interior look inward and upward but look outward and downward, they signify falsities confirmed by knowledges. Therefore also in what follows in Revelation, where falsities from that origin are treated of, it is said:

That the tails of the horses seen in vision were like unto serpents, and that they had heads with which they did hurt (Revelation 9:19).

And afterwards:

That the dragon with his tail drew the third part of the stars of heaven, and cast them to the earth (Revelation 12:3, 4);

which things may be seen explained below.

557. Verse 9. (Revelation 9:9) And they had breastplates as iron breastplates, signifies the persuasions with which they gird themselves for combats, against which the truths of the rational-spiritual man prevail not. This is evident from the signification of "breastplates" (or coats of mail), as being defenses against evils and falsities in combats, but here defenses of evils and falsities against goods and truths, because this treats of those who are in the falsities of evil in opposition to truths. Here "breastplates" signify persuasions, because sensual men who are in the falsities of evil, who are here described, do not fight against truths from reason, for they do not see truths, but falsities only, and are therefore in the persuasion that falsities are truths, consequently they fight solely from the persuasion of falsity, and with them this persuasion is such that the truths brought forth by the spiritual-rational man are of no avail, for they are repelled as a sword is from a breastplate or coat of mail. So "breastplates as iron breastplates" signify persuasions against which truths are of no avail. That the persuasiveness with such is so infatuating and suffocating that the spiritual-rational is of no avail against it may be seen above (n. 544, 549, 556). Moreover, breastplates or coats of mail, cover that part of the body called the breast or thorax, and this signifies the spiritual affection of truth; also all affection is contained in the sound which comes forth from the breast with the speech. But those who are here signified by "locusts," who are such sensual men as are in falsities, have no other affection than that of the love of self, and because that affection is full of self-confidence and full of the persuasion that their falsity is truth, and because that affection is in the sound which comes forth from the breast with the speech, so the locusts appeared in "breastplates which were as iron breastplates." Moreover, "iron" signifies truth in ultimates, and likewise falsity there, and at the same time what is hard; and the persuasiveness that they have causes the falsity to be so hard that the truths opposed to it rebound, as if they were of no account or avail. Because the persuasion of sensual men who are in falsities from self-confidence is such, and with spirits is so powerful that it suffocates and extinguishes the rational of other spirits with whom they converse in the world of spirits, it is severely prohibited, and those who make use of it are sent among spirits where they are distressed even to swooning by other spirits by means of still stronger persuasions, and this until they desist.

[2] Because breastplates or coats of mail were in use in wars, and to put them on signified to gird oneself for war and thus to fight, therefore in the Word those who were girt for fighting are said to have put on coats of mail. Thus in Jeremiah:

Harness the horses, and go up, ye horsemen; and stand ye forth in helmets; furbish the spears, and put on the coats of mail (46 Jeremiah 46:4).

These words do not mean the combat of one army against another, but the combat of the spiritual-rational man against the natural man who, from knowledges [scientifica] falsely applied, fights against truths and goods. For this is said of the army of Pharaoh king of Egypt, whom the king of Babylon smote, and "Pharaoh king of Egypt" means such a natural man, and "the king of Babylon," near the Euphrates, means the spiritual-rational man, therefore "Harness the horses, go up, ye horsemen, and stand ye forth in helmets; furbish the spears, and put on the coats of mail," signifies such things as relate to the combat of the spiritual-rational man against the natural man who is in falsities; "horses" mean the things of the understanding, "chariots to which they were harnessed" the things of doctrine, "horsemen" the intelligent, "helmets" the things of reason, "spears" truths combating, and "coats of mail" force and strength in fighting and resisting. A "coat of mail" has this meaning because it girds the breast, and from the breast through the arms is all the strength in fighting and resisting.

[3] In the same:

Against Babylon let him bend, let him that bendeth bend his bow; against her he shall lift himself up in his coat of mail (Jeremiah 51:3).

Here, too, "coat of mail" stands for the power to fight and resist. In Isaiah:

He put on righteousness as a coat of mail, and the helmet of salvation upon His head (Isaiah 59:17).

This treats of the Lord, and of the subjugation of the hells by Him; and "righteousness as a coat of mail" signifies the zeal for rescuing the faithful from hell and the Divine love of saving the human race; and as it was from the zeal of Divine love and power therefrom that the Lord fought and conquered, so righteousness is called a "coat of mail;" while the "helmet of salvation" signifies Divine truth from Divine good, by means of which is salvation, for a "helmet" has a similar signification as the head, because it is worn on the head; that the "head" in reference to the Lord signifies Divine truth and Divine wisdom will be seen in what follows.
