7950. 'Even to the firstborn of the prisoner who was in the dungeon' means falsified truths of faith that occupy the last place of all. This is clear from the meaning of 'the firstborn in the land of Egypt' as faith separated from charity, as just above in 7948, and so also falsified truth of faith, dealt with below; and from the meaning of 'the prisoner who is in the dungeon' as those who occupy the last place of all, for his firstborn is placed at the opposite end of the scale from 'Pharaoh's firstborn who was to sit on his throne', which means falsified truth of faith that occupies the first place, 7779, 7949. 'The prisoner who is in the dungeon' is used to mean in the spiritual sense closest to the actual words one who thinks only on the level of his physical senses, and so is in utterly thick darkness so far as matters of truth and good are concerned; for he does not even possess the ability to perceive, as those who think on a more internal level of the senses do. This is the reason why those who occupy the last place of all are meant.

[2] The reason why 'the firstborn in the land of Egypt' means falsified truth of faith is that 'the firstborn of Egypt' is faith separated from charity, 7948; and those with this kind of faith are in nothing but complete and utter darkness so far as truths of faith are concerned. They cannot be in any light, and so cannot at all perceive what truth is or whether something is true. This is because all spiritual light comes from the Lord through good, that is, through charity. For the good of charity is like a flame from which light radiates, since good comes of love, and love is spiritual fire, the source of enlightenment. Anyone who imagines that people leading an evil life can also receive enlightenment in the truths of faith is very much mistaken. Their state may be such that they are able to produce proofs, that is, they may be able to prove the teachings of their Church, sometimes with skill and ingenuity; yet they are not able to see whether the things they prove are true or not. The fact that even falsity can be proved so adroitly that it seems to be the truth, and that a person is wise not when he can prove that something is right but when he can see whether it is, see 4741, 5033, 6865, 7011, 7680.

[3] Therefore a person whose life is sunk in evil is steeped in falsity arising from his evil; and no matter how well he knows what is true he does not believe it. Sometimes he thinks he does, but he is mistaken. He will be allowed to know in the next life that he does not believe it, when his perceiving is made to conform to his desiring. When that is done he will disown the truth, oppose it, and spurn it, and will acknowledge its opposite - falsity - as the truth. This now explains why those who are governed by faith separated from charity cannot help falsifying the truths of faith.

4741. 'That they stripped Joseph of his tunic' means that they removed and annihilated the appearances of truth. This is clear from the meaning of 'stripping', when used in reference to Divine Truth represented here by 'Joseph', as removing and also annihilating; and from the meaning of 'tunic', because this consisted of various colours, as appearances of truth, dealt with in 4677. The removal and annihilation of the appearances of truth takes place once truth itself has been cast aside, for truth itself cannot but shine in people's minds, and no matter how much it is blotted out it remains visible, especially to those who are governed by good. Those who have annihilated truth see it too, and therefore they try to remove and annihilate even those appearances of it.

[2] Take an example to illustrate this. Who does not see that willing what is good and doing it is the whole essence of the Christian life? And if anyone is told that this is charity he is bound to agree. Indeed all who agree will go on to say that they know what willing and doing good is because this is a matter of life. But as for thinking, by the confidence imparted through faith, that this or that is true, as the adherents to faith separated from charity wish to do, they will say that they do not know what this is, for they can have no other conception of it than of smoke which vanishes. Now since faith alone and the confidence it imparts is seen to be like this by all who think seriously about it, especially by the good, those adherents to faith separated from charity strive to remove and annihilate even those appearances by cutting away every idea that is close to Divine Truth or in the neighbourhood of it. This is what is meant by stripping Joseph of the tunic that was on him.

[3] The same people also believe that those persons are wiser than all others who, once they have accepted some dogma, can substantiate it in various ways, and use various reasonings to present it as the truth. This however is anything but the mark of one who is wise. Anyone who is clever enough can do it, the wicked being more expert at it than the upright. Nor indeed is it the mark of a rational man; for a rational man can see from so to speak a higher viewpoint whether it is truth that is being substantiated or whether it is falsity. And this being what he sees he is quite unmoved by arguments substantiating falsity but regards them as senseless and absurd, no matter how much another person believes they are the result of wrestling to obtain pure wisdom. In short, it is anything but the mark of one who is wise, indeed anything but rationality, to be able to substantiate falsities; for it is the mark of a wise one, and it is rationality, when something is first seen to be the truth and is substantiated only after that. That is to say, seeing the truth implies seeing it by the light of heaven which comes from the Lord, but seeing falsity as truth implies seeing it by the inferior light which comes from hell.
