If fire also be a reason engaged in matter, and in this respect resemble the earth, it was not born by chance. Whence would it come?[93] Lucretius thought it came from rubbing (sticks or stones). But fire existed in the universe before one body rubbed another; bodies already possess fire when they rub up against one another; for it must not be believed that matter possesses fire potentially, so that it is capable of producing it spontaneously. But what is fire, since the principle which produces the fire, giving it a form, must be a "reason"? It is a soul capable of producing the fire, that is, a "reason" and a life, which (fuse) into one thing. That is why Plato says that in every object there is a soul[94]; that is, a power capable of producing the sense-fire. Thus the principle which produces the fire in our world is a "fiery life," a fire that is more real than ours. Since then the intelligible Fire is a fire more real than ours, it also possesses a moral life. The Fire-in-itself therefore possesses life. There is a similar "reason" in the other elements, air and water. Why should not these things be as animated as earth is? They are evidently contained in the universal living Organism, and they constitute parts thereof. Doubtless life is not manifest in them, any more than in the earth; but it can be recognized in them, as it is recognized in the earth, by its productions; for living beings are born in the fire, and still more in the water, as is better known; others also are formed in the air. The flames that we daily see lit and extinguished do not manifest in the universal Soul (because of the shortness of their duration); her presence is not revealed in the fire, because she does not here below succeed in reaching a mass of sufficient permanency. WATER AND AIR AS INTELLIGIBLE ENTITIES. It is not otherwise with water and air. If by their nature these elements were more consistent, they would reveal the universal Soul; but as their essence is dispersed, they do not reveal the power that animates them. In a similar case are the fluids occurring in our body, as, for instance, the blood; the flesh, which seems animated, is formed at the expense of the blood.[95] The latter must therefore enjoy the presence of the soul, though it seem deprived of the (soul) because (the blood) manifests no sensibility, opposes no resistance, and by its fluidity easily separates itself from the soul that vivifies it, as happens to the three elements already mentioned. Likewise the animals which Nature forms out of condensed air feel without suffering.[96] As fixed and permanent light penetrates the air so long as the air itself is permanent, the soul also penetrates the atmosphere surrounding her without being absorbed by it. Other elements are in the same case. THE INTELLIGIBLE WORLD IS A COMPLETE MODEL OF THIS OUR UNIVERSE.
