V. Plant, Animal, Man

In a living organism there is, however, a reciprocal relationship of all parts. Hence in the animal the excretion towards the lifeless realm, which in the plant approaches very nearly to the outer lifeless world, the mineral, still remains far removed from mineral nature. In the bark-forming process of the plant, we see the forming of a substance which is already on the way to mineral nature and loosens itself from the plant-organism increasingly, the more mineral it becomes; this appears in the animal as the excreted products of digestion. These are farther removed from the mineral nature than the excretions of the plant.
