8. Among the animals which have not reason one life is distributed; but among reasonable animals one intelligent soul is distributed: just as there is one earth of all things which are of an earthy nature, and we see by one light, and breathe one air, all of us that have the faculty of vision and all that have life. 9. All things which participate in anything which is common to them all move towards that which is of the same kind with themselves. Everything which is earthy turns towards the earth, everything which is liquid flows together, and everything which is of an aerial kind does the same, so that they require something to keep them asunder, and the application of force. Fire indeed moves upwards on account of the elemental fire, but it is so ready to be kindled together with all the fire which is here, that even every substance which is somewhat dry is easily ignited, because there is less mingled with it of that which is a hindrance to ignition. Accordingly, then, everything also which participates in the common intelligent nature moves in like manner towards that which is of the same kind with itself, or moves even more. For so much as it is superior in comparison with all other things, in the same degree also is it more ready to mingle with and to be fused with that which is akin to it. Accordingly among animals devoid of reason we find swarms of bees, and herds of cattle, and the nurture of young birds, and in a manner, loves; for even in animals there are souls, and that power which brings them together is seen to exert itself in the superior degree, and in such a way as never has been observed in plants nor in stones nor in trees. But in rational animals there are political communities and friendships, and families and meetings of people; and in wars, treaties, and armistices. But in the things which are still superior, even though they are separated from one another, unity in a manner exists, as in the stars. Thus the ascent to the higher degree is able to produce a sympathy even in things which are separated. See, then, what now takes place; for only intelligent animals have now forgotten this mutual desire and inclination, and in them alone the property of flowing together is not seen. But still, though men strive to avoid [this union], they are caught and held by it, for their nature is too strong for them; and thou wilt see what I say, if thou only observest. Sooner, then, will one find anything earthy which comes in contact with no earthy thing, than a man altogether separated from other men. 10. Both man and God and the universe produce fruit; at the proper seasons each produces it. But and if usage has especially fixed these terms to the vine and like things, this is nothing. Reason produces fruit both for all and for itself, and there are produced from it other things of the same kind as reason itself.
