IN the preceding chapter, we have stated what correspondence is, and have explained as well that absolutely everything in the soul’s body is a correspondence. Next in orderly sequence we need to explain that everything earthly and in general everything in our world is a correspondence.
All earthly things are differentiated into three classes that we call “kingdoms,” namely the animal kingdom, the vegetable kingdom, and the mineral kingdom. Members of the animal kingdom are correspondences on the first level because they are alive. Members of the vegetable kingdom are correspondences on the second level because they merely grow. Members of the mineral kingdom are correspondences on the third level because they neither live nor grow.
The correspondences in the animal kingdom are the living creatures of various kinds, both those that walk and creep on the earth and those that fly in the air. We need not list them by name, because they are familiar. Correspondences in the vegetable kingdom are all the things that grow and bloom in gardens and forests and farms and meadows, which again are so familiar that they need not be listed by name. Correspondences in the mineral kingdom are metals noble and base, stones precious and common, and soils of various kinds, as well as bodies of water. Beyond these, things made from these elements by human industry for our use are correspondences, things such as foods of all kinds, garments, houses, major buildings, and so on.
