The somewhat irksome phraseology of Baron Swedenborg has dulled many minds to a sense of his great acumen and philosophical depth, but it maybe convenient to summarize his scientific doctrine of "Correspondences" in this place as it has an important bearing on the subject in hand. He laid down the principle of the spiritual origin of force and matter. Matter, he argued, was the ultimate expression of spirit, as form was that of force. Spirit is to force what matter is to form--its substratum. Hence for every spiritual force there is a corresponding material form, and thus the material or natural world corresponds at all points to the world of spirit, without being identical. The apparent hiatus between one plane of existence and the next he called a discrete degree, while the community between different bodies on the same plane he called a continuous degree. Thus there is community of sensation between bodies of the same nature, community of feeling, community of thought, and community of desire or aspiration, each on its own plane of existence. But desire is translated into thought, thought into feeling, and feeling into action. The spirit, soul (rational and animal in its higher and lower aspects), and the body appear to have been the principles of the human constitution according to this authority. All spirits enjoy community, as all souls and all bodies on their respective planes of existence; but between spirit and soul, as between soul and body, there is a discrete degree. In fine, mind is continuous of mind all through the universe, as matter is continuous of matter; while mind and matter are separated and need to be translated into terms of one another. Taking our position from the scientific statement of the atomic structure of bodies, atomic vibration and molecular arrangement, we may now consider the action exerted by such bodies upon the nervous organism of man.
