374. (2) There is a correspondence of the will and understanding with the heart and lungs, consequently a correspondence of all things of the mind with all things of the body. This is new: it has hitherto been unknown because it has not been known what the spiritual is, and how it differs from the natural; therefore it has not been known what correspondence is; for there is a correspondence between things spiritual and things natural, and by means of correspondence they are conjoined. It is said that heretofore there has been no knowledge of what the spiritual is, or of what its correspondence with the natural is and therefore what correspondence is; yet these might have been known. Who does not know that affection and thought are spiritual, therefore that all things of affection and thought are spiritual? Who does not know that action and speech are natural, therefore that all things of action and speech are natural: who does not know that affection and thought, which are spiritual, cause man to act and to speak? From this who cannot see what correspondence is between things spiritual and things natural? Does not thought make the tongue speak, and affection together with thought make the body act? There are two distinct things: I can think without speaking, and I can will without acting; and the body, it is known, neither thinks nor wills, but thought falls into speech, and will descends into action. Does not affection also beam forth from the face, and there exhibit a type of itself? This everyone knows. Is not affection, regarded in itself, spiritual, and the change of countenance, called the expression, natural? From this who might not conclude that there is correspondence; and further, a correspondence of all things of the mind with all things of the body; and since all things of the mind have relation to affection and thought, or what is the same, to the will and understanding, and all things of the body to the heart and lungs, - that there is a correspondence of the will with the heart and of the understanding with the lungs? Such things have remained unknown, though they might have been known, because man has become so external as to be unwilling to acknowledge anything except the natural. This has become the joy of his love, and from that the joy of his understanding; consequently it has become distasteful to him to raise his thought above the natural to anything spiritual separate from the natural; therefore, from his natural love and its delights, he can think of the spiritual only as a purer natural, and of correspondence only as a something flowing in by continuity; yea, the merely natural man cannot think of anything separate from the natural; any such thing to him is nothing. Again, these things have not heretofore been seen and known, because everything of religion, that is, everything called spiritual, has been banished from the sight of man by the dogma of the whole Christian world, that matters theological, that is, spiritual, which councils and certain leaders have decreed, are to be believed blindly because (as they say) they transcend the understanding. Some, therefore, have imagined the spiritual to be like a bird flying above the air in an ether to which the sight of the eye does not reach; when yet it is like a bird of paradise, which flies near the eye, even touching the pupil with its beautiful wings and longing to be seen. By the sight of the eye intellectual vision is meant.
