RELATION OF DESIRE-FUNCTION TO THE VEGETATIVE POWERS.
22. It is possible, even in plant-life, to distinguish something which is the characteristic property of their bodies, and a power that imparts it to them. What in us in the soul’s faculty of desire, is in plant-life the natural element (or, vegetative power).
PLATO IS IN DOUBT ABOUT THE EARTH’S SOUL; WHETHER SHE IS LIKE THOSE OF STARS.
The earth also possesses a soul; and therefore also such a potentiality; and it is from the earth that the plants derive their vegetative potentiality. One might reasonably first ask which is this soul that resides in the earth. Does she proceed from the sphere of the universe (to which alone Plato seems to attribute a soul from the very first), so as to make of her an irradiation of this sphere upon the earth ? Or should we on the contrary, attribute to the earth a soul similar to that of the stars, as Plato does when he calls the earth the first and most ancient of the divinities contained within the interior of the heavens? Could it, in this case, be a divinity, if it did not have a soul? It is therefore difficult to determine the exact state of affairs, and the very words of Plato here instead of diminishing our embarrassment, only increase it.
At first, how will we manage to form a reasonable opinion on this subject? Judging from what the earth causes to grow, one might conjecture that it possesses the vegetative potentiality. As many living beings are seen to grow from the earth, why would it itself not be a living being? Being besides a great living being, and a considerable part of the world, why should the earth not possess intelligence, and be a divinity? Since we consider every star as a living being, why would we not similarly consider the earth, which is a part of the universal living being? It would, indeed, be impossible to admit that it was exteriorly contained by a foreign soul, and that interiorly it would have no soul, as if it were the only being incapable of having an individual soul. Why should we grant animation to the (starry) bodies of fire, while not to the earthly body of our earth? Indeed, bodies could as easily be of earth as of fire. Not in the stars, any more than in the earth, is there any nose, flesh, blood, or humours, although the earth is more varied than the stars, and although it be composed of all the other living bodies. As to its inability to move, this can be said only in reference to local motion. (For it is capable of motion in the respect that it can feel.)
THE EARTH CAN FEEL AS WELL AS ANY OF THE STARS.
It will be asked, But how can the earth feel? We shall answer in turn, How can stars feel ? It is not the flesh that feels; a soul is not dependent for feeling on a body; but the body is dependent on the soul for self-preservation. As the soul possesses judgment, she should be able to judge the passions of the body whenever she applies her attention thereto.
QUESTION: WHAT PASSIONS WOULD BE SUITABLE TO THE EARTH?
It may however still be asked, What are the passions characteristic of the earth, and which may be objects of judgment for the soul? It may besides be objected that the plants, considered in the terrestrial element that constitutes them, do not feel.
SENSATION WILL FIRST HAVE TO BE EXAMINED.
Let us now examine to what beings sensation belongs, and whereby it operates. Let us see whether sensation can take place even without organs. Of what use to the earth could sensation be? For it does not serve the earth as means of knowledge; the knowledge which consists in wisdom suffices for the beings to whom sensation is of no use. This consideration might however be denied, for the knowledge of sense-objects offers, besides utility, some of the charms of the Muses. Such is, for example, the knowledge of the sun and the other stars, whose contemplation itself is agreeable. This problem will therefore demand solution.
RESTATEMENT OF PROBLEMS INVOLVED.
We must therefore first investigate if the earth possess senses, to what animals sensation naturally belongs, and how sensation operates. It will be necessary to begin by discussing the doubtful points that we have indicated, and to examine in general if sensation can operate without organs, and if the senses have been given for utility, admitting even that they can procure some other advantage.
