75. It is different for us, since we have not only desires of earthly love but desires of spiritual love and desires of heavenly love as well. Our human mind has three levels, as I explained in part 3 of Divine Love and Wisdom. This means that we can rise from earthly knowledge to spiritual intelligence and from there to heavenly wisdom; and because of these latter two, the intelligence and the wisdom, we can turn to the Lord, be united to him, and therefore live forever. This raising of our desires would not be possible, though, if we did not have the ability to raise our discernment because we are rational and to do so intentionally because we are free.

[2] It is by means of these two abilities that we can think inwardly about what we are perceiving outwardly with our physical senses and can think on a higher level about what we are thinking on a lower level. Any one of us can say, "I was thinking about this," or "I am thinking about this," or "I intended this," or "I intend this," or "I understand that this is true," or "I love this because of its quality," and so on. We can see from this that we are able to think about our thinking from a higher perspective and apparently see it down below. This ability of ours comes from our rationality and our freedom. Rationality enables us to think on a higher level, and freedom enables us to think that way from desire, intentionally. If we did not have the freedom to think that way, that is, we would not have the intention and therefore would not have the thought.

[3] The result is that if we do not want to understand anything except what has to do with this world and its nature, if we do not want to understand what is good and true on moral and spiritual levels, we cannot rise from knowledge into intelligence, let alone from intelligence into wisdom, because we have blocked off these abilities. We have then made ourselves human only in the limited sense that we could understand if we wanted to, because of our inborn rationality and freedom and because we are able to want to.

It is these two abilities that enable us to think and to express our thoughts by talking. In other respects, we are not people but animals, and actually worse than animals because of our misuse of these abilities.

598. Man cannot be reformed unless he has freedom, for the reason that he is born into evils of every kind; and these must be removed in order that he may be saved; and they cannot be removed unless he sees them in himself and acknowledges them, and afterwards ceases to will them, and finally holds them in aversion. Not until then are they removed. And this cannot be done unless man is in good as well as in evil, since it is from good that he is able to see evils, while from evil he cannot see good. The spiritual goods that man is capable of thinking he learns from childhood by reading the Word and from preaching; and he learns moral and civil good from his life in the world. This is the first reason why man ought to be in freedom.

[2] Another reason is that nothing is appropriated to man except what is done from an affection of his love. Other things may gain entrance, but no farther than the thought, not reaching the will; and whatever does not gain entrance into the will of man does not become his, for thought derives what pertains to it from memory, while the will derives what pertains to it from the life itself. Only what is from the will, or what is the same, from the affection of love, can be called free, for whatever a man wills or loves that he does freely; consequently man's freedom and the affection of his love or of his will are a one. It is for this reason that man has freedom, in order that he may be affected by truth and good or may love them, and that they may thus become as if they were his own.

[3] In a word, whatever does not enter into man's freedom has no permanence, because it does not belong to his love or will, and what does not belong to man's love or will does not belong to his spirit; for the very being [esse] of the spirit of man is love or will. It is said love or will, since a man wills what he loves. This, then, is why man can be reformed only in freedom. But more on the subject of man's freedom may be seen in the Arcana Coelestia in the passages referred to below.
