While we at first apprehend animals and plants as units, not seeing the individual cells by which they are composed, we, in the national organisms, on the contrary, first perceive the cells themselves—the human individuals—but are unable to grasp the nations as individually living organisms. On the one hand we see directly only the social side, on the other, only the organic. If there are beings observing the human community as we see plants and animals, they would comprehend society as a unit composed of different trades and industries, but not as composed of men, who are the building material in these members. If such postulated observers made an invention corresponding to our microscope, they would be surprised to find the social organism composed of human individuals, which fact would seem just as mystical to them as the cells seemed at first to us. So far as we have derived from experience a knowledge of organic structure, it reveals itself to us as _an individual composed of more primitive and elementary individuals_. These elementary units of lower kind and order might consequently be called a spiritual body in a literal sense. From the point of view of the elementary constituent, each organism is a community, a unit of similar, independently living, individuals; from the point of view of the organs and of the whole, this community itself is a living individual of higher potency and may in its turn enter as an elementary organism in a spiritual body of still higher power, and so on, in a geometric series. Man enters into the social organism, but is himself composed of cell-organisms, which in turn consist of more primary units. Organic structure shows everywhere the same general qualities, the same fundamental features. Each higher and more complex organism repeats in a more perfect way and in a higher potency exactly the same general forms of organization as its elementary constituents have shown in their own sphere. Hence the surprising similarity in the structure of the organisms. When we know one we know all. This would, of course, be neither possible nor conceivable if the spiritual bodies, which form their corporal structure, did not possess corresponding similar fundamental qualities.
