3577. As it appears therefore that throughout the universe use can never be separated from organic substances, there results hence a reason for the use of ultimates in nature; they flow from the uses of external organic substances. Use separate from organic substances is not given in the created universe, thus [it flows] necessarily from the Lord. But that all use might be seen from ultimates, is a consequence of man's being born such a being as he is - one who is to be instructed by sensual things; but his sight extends from external to internal things by a removal of the external, or, as it were, by their death, for when the external are removed, the internal appear, and upon their removal, things still more interior, so that finally there are no externals. Thus by removals and rejections [from before to] behind the internal, a way from the posterior to the prior is given - a process with which man is familiar. - 1748, October 15.
