1003. The basis of both kingdoms is therefore exactly similar; the vesicle and the mucus lie at the foundation of both. It depends solely upon the surrounding element, whether out of one and the same mass this or that organism should arise, or rather upon the active influence of the light, this being conditioned only by the elements. Not a word can accordingly be spoken about preformation. In darkness-organism the water-vesicle has been placed between earth and air, and thus fettered to the earth; in light-organism, however, the vesicle has been placed in the water and so freed from the earth. 1004. The planetary organism has, in accordance with its situation and import, been bound to the earth. It must originate like the metal in the earth, in the darkness and, as it were, in a vein. But it is at the same time a light-product; it must rise from out of the earth into the air and towards the light. It is a mucus, living metallic vein, which elevates itself from out the earth into the air. 1005. This organism, which originates in the darkness of the earth, and grows therefrom into the air so as to meet the light, is _plant_. 1006. The solar-organism is, in accordance with its import, void of connexion with the earth; like a planet it revolves freely about the earth, and everywhere receives its image or likeness in the influence of all four elements. 1007. The organism, which, free from the earth, has originated in water, or properly speaking, in the transparency, is _animal_. 1008. The vegetable and animal are the only organic, kingdoms. In both, nature has exhausted herself, and has in the last kingdom, as in a mirror, been wholly reflected. They are together planet and sun, or thus solar system. But since the animal comprehends all elements in itself, so it contains also the plant, and is therefore for itself vegetable and animal kingdom, or the whole solar-system. 1009. The plant hath no free system of motion, because motion is wanting to it; bound to the elements, by these it is determined. The element of motion, the æther, lies apart from it. It has only motion, if and while the elements act upon, or solicit it, thereunto. 1010. It moves itself only by an external or _foreign_ stimulus. If no foreign stimulus be present, it does not move itself. A root grows, moves itself towards one spot, not because it there _seeks_ for moisture, but because it is _affected_ by the moisture which is there found. Were the moisture not to act upon it, it would wither. 1011. The animal has independent motion. For it has indeed taken up the centre, the earth-and the light-system which is the principle of motion, into itself. 1012. Thus the animal moves itself independently of external stimuli. The animal can move itself from _want_ of stimulus. It moves itself to _seek_ for, and thus from want of, nourishment, which consequently does not act upon it; the plant cannot, however, move itself owing to want of food, but only die.
