410. (xii) Love or the will conjoins itself to wisdom or the understanding, and causes wisdom or the understanding to be reciprocally conjoined to it. That love or the will conjoins itself to wisdom or the understanding is plain from their correspondence with the heart and lungs. Anatomical observation teaches that the heart comes into its life's motion when the lungs are not yet in motion. Experience teaches it by those who suffer from swoons and suffocation, also from embryos in the womb, and chicks in eggs. Knowledge of anatomy also teaches that the heart, while it is acting alone, forms and adapts the lungs so that it may put the respiration in motion there; and that it also forms the other viscera and organs so that it may perform various uses in them, the organs of the face that it may have sensation, the organs of motion that it may act, and the rest of the bodily organs that it may exhibit uses corresponding to the affections of love. From these things it can now for the first time be shown that just as the heart produces such things on account of the varied activities it is about to perform in the body, so love produces corresponding things in its receptacle, the will, for the sake of the various affections that make up its form, which, as was shown above, is the human form. Now since the first and nearest affections of love are the affections for knowing, for understanding, and for seeing what it knows and understands, it follows that love forms the understanding for them, and actually comes into them when it begins to feel and to act, and to think. The understanding contributes nothing to this, as is evident from the analogy of the heart and lungs (see above). From these things it can be seen that love or the will conjoins itself to wisdom or the understanding, and not wisdom or the understanding to love or the will; and it is further evident that the knowledge which love acquires to itself from the affection for knowing, and the perception of truth which it acquires from the affection for understanding, and thought which it acquires from the affection for seeing what it knows and understands, do not come from the understanding, but from love. Thoughts, perceptions, and knowledges therefrom, do indeed flow in from the spiritual world, yet are not received by the understanding, but by love in accordance with its affections in the understanding. It appears as if the understanding receives them, and not love or the will, but it is an illusion. It appears also as if the understanding unites itself to love or the will, but this also is an illusion. Love or the will conjoins itself to the understanding and makes the union reciprocal. This reciprocal conjunction comes from love's marriage with it. The conjunction thence is made seemingly reciprocal from the life and consequent power of love. It is the same with the marriage of good and truth, for good is of love, and truth is of the understanding. Good does everything, it receives truth into its home, and conjoins itself with truth as far as it is in harmony. Good may also admit truths which are not in harmony, but this it does from an affection for knowing, understanding, and thinking its own things, while it is not yet determined upon the uses which are its ends, and are called its goods. There is absolutely no reciprocal conjunction, or conjunction of truth with good, what is conjoined reciprocally comes from the life of good. From this it is that every man and every spirit and angel is judged by the Lord according to his love or good, and no one according to his understanding, or truth separate from love or good. For man's life is his love, as was shown above, and his life is according as he has exalted his affections by means of truths, that is, in accordance as his affections have been perfected by love. Love's affections are exalted and perfected by means of truths, thus by wisdom; and then love acts conjointly with its wisdom, as if from it, but actually of itself through wisdom, as through its own form, which form receives nothing whatever from understanding, but everything from some fixed purpose of love which is called affection.
