310. (i) In the earths there is a conatus to produce uses in forms, that is, forms of uses. It is evident from their source that there is this conatus in earths. The substances and matters of which earths consists are endings and terminations of the atmospheres which go forth as uses from the spiritual Sun, (see above n. 305, 306). And because the substances and matters of which earths consist are from that source, and their aggregates are held in connection by the pressure of the surrounding atmospheres, it follows that hence they have a perpetual conatus towards producing forms of uses. It is from their origin that they derive the very quality which enables them to produce, being as they are the ultimates of the atmospheres with which they therefore accord. It is said that such a conatus and quality are in the earths, but it is understood that they are present in the substances and matters of which the earths consist, whether they are in the earths or exhaled from the earths into the atmospheres. It is well known that atmospheres are full of such exhalations. That there is such a conatus and such a quality in the substances and matters of earths is clearly evident from the fact that seeds of every kind, opened up to their innermost by means of heat, are impregnated by the most subtle substances which can have no other than a spiritual origin, and through which they have power to conjoin themselves to use out of which is their prolific nature. Then through conjunction with matters from a natural origin, they are able to produce forms of uses, and finally deliver them as from a womb so that they may also come into the light, and thus germinate and grow. This conatus is afterwards continuous from the earths through the root even to ultimates and from ultimates to firsts wherein the use itself lies in its origin. Thus uses pass over into forms. And forms in their progression from firsts to ultimates, and from ultimates to firsts derive from use, which is like a soul, that each and everything of the form is of some use. Use is said to be like a soul because its form is like a body. It also follows that there is a more interior conatus which is the conatus of producing uses for the animal kingdom through germinations, for by such, animals of every kind are nourished. It follows further that in all these there is also an inmost conatus which is that of performing a use to the human race. From this origin these things follow:
