409. (11) Love or the will does nothing except in conjunction with wisdom or the intellect. Since love has no sensory life and no active life apart from the intellect, and since love introduces the intellect into all the constituents of the mind, as we showed in nos. 407 and 408 above, it follows that love or the will does nothing except in conjunction with wisdom or the intellect. For what is it to act from love apart from the intellect? It can only be called irrational, for it is the intellect that teaches what ought to be done and how it ought to be done. Love without the intellect does not know this. Therefore such a marriage exists between love and the intellect that although they are two distinct entities, they nevertheless operate as one. A like marriage exists between good and truth, for goodness is a property of love, and truth a matter of the intellect. Such a marriage exists in every single constituent of the universe that has been created by the Lord. Their usefulness has relation to good, and the form of their usefulness to truth. [2] It is owing to this marriage that every single constituent of the body has a right and left side, the right side having relation to good from which springs truth, and the left side to truth springing from good, thus [the two together] to their conjunction. It is because of this that we find paired organs in the human being. The brain has two component structures,* the cerebrum two hemispheres, the heart two ventricles, the lungs two lobes. There are two eyes, ears, nostrils, arms, hands, loins, feet, kidneys, and testicles, among others. And where the organs are not paired, there is a right and left side. These pairs exist because good looks to truth for its expression, and truth looks to good for its being. The same is the case in the angelic heavens and in each of their societies. For more on this subject, see no. 401 above, where we showed that love or the will cannot do anything through its human form without a marriage with wisdom or the intellect. As for the conjunction of evil and falsity, which is the opposite of the conjunction of good and truth, this we will speak of elsewhere. * I.e., the cerebrum and cerebellum.
