7750. As by a bird of stone were represented those who are in knowledges alone, and not in a life of love, and who consequently have scarcely any spiritual life, therefore here, by way of appendix, I may show that those only have spiritual life who are in heavenly love, and from this in knowledges; and that every love contains within it all power to know what belongs to that love. Take for example the animals of the earth, and also the animals or birds of heaven. These have the knowledge of all things of their love. Their loves are to feed themselves, to dwell safely, to propagate offspring, to rear their young; and they have all the requisite knowledge for these purposes; for this is in these loves, and flows into these creatures as into its own receptacles. This knowledge is in some cases so extraordinary that man cannot but be amazed at it. It is said to be inborn, and is called instinct; but it is of the love in which they are.
 If man were in his own love, which is love to God and toward the neighbor, this being man's proper love by which he is distinguished from the beasts, he would then be not only in all requisite knowledge, but also in all intelligence and wisdom; neither would he have occasion to learn them, for they would flow in from heaven into these loves, that is, through heaven from the Divine. But as man is not in these, but in contrary loves, namely, in the love of self and the love of the world, therefore he must needs be born into all ignorance and lack of skill; yet by Divine means he is brought to something of intelligence and wisdom, but still not actually into anything unless he removes the loves of self and of the world, and thus opens the way for love to the Lord and love toward the neighbor.
 That love to the Lord and love toward the neighbor have within them all intelligence and wisdom, can be seen from those who in the world have been in these loves, for when in the other life they come into heaven, they there know and are wise in such things as before they had never known; nay, they think and speak there as do the rest of the angels such things as the ear has never heard, nor the mind known, which are unutterable. The reason is that these loves have in them the capacity to receive such things.
