That spirits and angels have memory, I have also learned from much experience; for I have seen that all things which they had thought and done, both in public and in private, were called forth from their memory when they were with other spirits; and also that they who were in any truth from simple good, were imbued with knowledges and thereby with intelligence, and were afterwards taken up into heaven.
But it is to be observed that none are imbued with knowledges and thereby with intelligence, beyond the degree of affection for good and truth in which they were when in the world; for the affection of every spirit and angel remains, both in quality and intensity, such as it had been in the world, although it is afterwards perfected by impletion, which also is continued through eternity. For there is nothing but what is capable of being filled up to eternity, since everything may be infinitely varied, thus enriched by various things, consequently multiplied and fructified. No end can be assigned to any good thing, because it springs from the Infinite. (H. H. 461-469.)
