First it can be demonstrated that plants contain nothing opposed to reason; since, even here below, a plant contains a "reason" which constitutes its life.[91] But if the essential "reason" of the plant, which constitutes it, is a life of a particular kind, and a kind of soul, and if this "reason" itself be a unity, is it the primary Plant? No: the primary Plant, from which the particular plant is derived, is above that "reason." The primary Plant is unity; the other is multiple, and necessarily derives from this unity. If so, the primary Plant must possess life in a still higher degree, and be the Plant itself from which the plants here below proceed, which occupy the second or third rank, and which derive from the primary Plant the traces of the life they reveal. HOW THE EARTH EXISTS IN THE INTELLIGIBLE. But how does the earth exist in the intelligible world? What is its essence? How can the earth in the intelligible world be alive there? Let us first examine our earth, that is, inquire what is its essence? It must be some sort of a shape, and a reason; for the reason of the plant is alive, even here below. Is there then a living ("seminal) reason" in the earth also? To discover the nature of the earth, let us take essentially terrestrial objects, which are begotten or fashioned by it. The birth of the stones, and their increase, the interior formation of mountains, could not exist unless an animated reason produced them by an intimate and secret work. This reason is the "form of the earth,"[92] a form that is analogous to what is called nature in trees. The earth might be compared to the trunk of a tree, and the stone that can be detached therefrom to the branch that can be separated from the trunk. Consideration of the stone which is not yet dug out of the earth, and which is united to it as the uncut branch is united to the tree, shows that the earth's nature, which is a productive force, constitutes a life endowed with reason; and it must be evident that the intelligible earth must possess life at a still higher degree, that the rational life of the earth is the Earth-in-itself, the primary Earth, from which proceeds the earth here below. THE FIRE AS IT IS IN THE INTELLIGIBLE WORLD.
