464. Although the external or natural memory remains in man after death, the merely natural things in it are not reproduced in the other life, but only the spiritual things adjoined to the natural by correspondences; but when these are present to the sight they appear in exactly the same form as they had in the natural world; for all things seen in the heavens have just the same appearance as in the world, although in their essence they are not natural but spiritual (as may be seen in the chapter on Representatives and Appearances in Heaven, n. 170-176). [2] But the external or natural memory in respect to the things in it that are derived from the material, and from time and space, and from other properties of nature, is not serviceable to the spirit in the way that it was serviceable to it in the world, for whenever man thinks in the world from his external sensual, and not at the same time from his internal or intellectual sensual, he thinks naturally and not spiritually; but in the other life when he is a spirit in the spiritual world he does not think naturally but spiritually, and to think spiritually is to think intellectually or rationally. For this reason the external or natural memory in respect to its material contents is then quiescent, and only those things that man has imbibed in the world by means of material things, and has made rational, come into use. The external memory becomes quiescent in respect to material things because these cannot then be brought forth, since spirits and angels speak from those affections and thoughts that are proper to their minds; and are therefore unable to give expression to any thing that is not in accord with their affections and thoughts as can be seen in what is said about the speech of angels in heaven and their speech with man (n. 234-257). [3] Because of this man after death is rational, not in the degree that he was skilled in languages and sciences in the world, but in the degree in which he became rational by means of these. I have talked with many who were believed in the world to be learned because they were acquainted with ancient languages, such as the Hebrew, Greek, and Latin, but had not cultivated their rational faculty by what is written in those languages. Some of them were seen to be just as simple as those who knew nothing of those languages, and some even stupid, and yet they retained the conceit of being wiser than others. [4] I have talked with some who had believed in the world that man is wise in the measure of the contents of his memory, and who had stored up many things in their memory, speaking almost solely from the memory, and therefore not from themselves but from others, and their rationality had not been at all perfected by means of the things in their memory. Some of these were stupid and some sottish, not in the least comprehending whether a truth is true or not, and seizing upon all falsities that are passed off for truths
