7424. 'And there were lice on man and on beast' means that evils rose up from those things - interior and exterior evils attached to wicked desires. This is clear from the meaning of 'lice' as evils, dealt with in 7419; from the meaning of 'man' as good, dealt with in 4287, 5302, and so in the contrary sense as evil; and from the meaning of 'beast' as the affection for good, and in the contrary sense as the affection for evil, which is evil or wicked desire, dealt with in 45, 46, 142, 143, 246, 714, 715, 719, 776, 2179, 2180, 3218, 3519, 5198. But when the expression 'man and beast' is used, man' means interior good, and in the contrary sense interior evil, while 'beast' means exterior good, and in the contrary sense exterior evil. The reason why 'man' means interior good or interior evil is that a person is truly human by virtue of his internal man and the nature of this, not by virtue of his external man; for without the internal the external man is not truly human. If the external man too is to be truly human it must be completely subject to the internal, so completely that it does not act by itself, only from the internal. The reason why 'beast' means exterior good and in the contrary sense exterior evil is that beasts do not have an internal side to them like that present in a human being. With them the internal side is merged into the external, so completely that it makes one with it, and at the same looks downwards or towards the ground without any uplifting towards more internal things. The expression 'evils attached to wicked desires' is used because all evils are objects of wicked desires; for wicked desires are the longings of a person's loves. What makes interior evils different from exterior evils is this: Interior evils belong to thought and will, whereas exterior evils belong to actions. The fact that evils may be interior without being exterior is evident from the consideration that a person can be evil and yet to outward appearance look like an upright man, indeed like a man possessing faith and conscience. Some even know how to pretend to be angels when in fact inwardly they are devils. This is how great the difference can be between the inward appearance, which is that presented by the spirit, and the outward appearance, which is that presented by the body.

714. That 'every clean beast' means affections for good is clear from what has been stated and shown already about beasts in 45, 46, 142, 143, 246. The reason affections are meant by this is that a human being regarded in himself and his proprium is no different from a beast. His [five] senses are very similar, appetites very similar, natural desires very similar, as well as all his affections being very similar. His good and even his best loves are very similar, such as loving companions of his own species, loving his offspring, and loving his married partner. To this extent there is no difference at all. He is a human being and superior to beasts however in that he has an inner life which neither does nor can exist with beasts. That life is the life of faith and love deriving from the Lord, and unless that life were present in the smallest characteristic which a human being shares in common with beasts he would not be in any way different. Take just one example - love towards companions. If he were to love them merely for his own sake without anything more heavenly or more divine within such love, he could not then be called a human being, for the same is true of beasts. Similarly with every other example that could be taken. Consequently if the life of love from the Lord were not present in his will, and the life of faith from the Lord in his understanding, he would in no way be human. Through the life he has from the Lord he lives on after death, for the Lord takes him to Himself; and in this way he can be with angels in His heaven and live for ever. And even when someone lives like a wild animal, loving nothing whatever but himself and things regarding himself, still the Lord's mercy, being Divine and Infinite, is so great that He does not abandon him but by means of angels continually breathes His life into him. And even though someone does not receive that life otherwise than as a wild animal the Lord still makes it possible for him to think, reflect, and understand whether something in private or public life, or something worldly or bodily is good or bad, and so whether it is true or false.
