560. And stings were in their tails, signifies craftiness in deceiving by means of them. This is evident from the signification of "stings," as being craftiness and shrewdness in persuading as to falsities; it follows therefore that they had in them the power to hurt men, for one who deceives craftily and shrewdly is especially harmful. The stings were "in their tails," because they deceive by means of knowledges [scientifica] sensually perceived, knowledges both from the Word and from the world, which are what human learning consists of; they deceive by knowledges from the Word by explaining it sensually according to the letter, and not according to its interior sense; they deceive by knowledges from the world by using them for confirmation. It is to be known that sensual men are more crafty and shrewd than others, and thus in acutely deceiving; for as spiritual men possess intelligence and prudence, so those who are sensual and in falsities possess malice and craftiness, for all malice has its seat in evil, as all intelligence has its seat in good. [2] It is believed in the world that those who are crafty and shrewd are also prudent and intelligent; but craftiness and malice are not prudence and intelligence, but viewed in themselves are insanity and folly; for such remove themselves from eternal happiness and cast themselves into eternal misery, and this is not the part of the prudent and intelligent but of the insane and foolish. Moreover, with such all things of heavenly and angelic wisdom are in dense darkness, and where that wisdom is thick darkness there is folly. That sensual men are crafty and shrewd can be seen from those who are in the hells, where all are merely natural and sensual; it can hardly be believed by anyone how much craftiness and shrewdness these possess (see in the work on Heaven and Hell, n. 576-581, where the malice and wicked devices of the infernal spirits are treated of). [3] That "stings" signify craftiness can be seen without confirmation from the Word, for in common discourse the craftiness in speech by which men are deceived are called sharp points, and the talk itself is called sharp. But "stings" signify particularly interior falsities, which are such as cannot be dispelled, because they are from the knowledges and fallacies of the senses. That such falsities are signified by "stings" (or sharp points) can be seen from representatives in the spiritual world, where interior falsities are represented in various ways by sharp things, like the points of swords, the points of arrows, and things pointed in various forms, and this when they are intended to hurt; for this reason it is also forbidden there to exhibit such things to view, for spirits when they see them become furious to inflict injury. [4] These falsities are signified by "sharp instruments" in Amos:
