All these planets contribute to the Whole. Their mutual relation,
therefore, is one suitable to the universe, just as the organs of an
animal are shaped to take part in the organism they constitute.[208]
Take, for instance, a part of the body, such as the bile, which serves
both the whole animal that contains it, and its special organ, inasmuch
as it was necessary to arouse courage, and to oppose the injury of
both the whole body, and its special organ. There had to be something
similar (to bile) in the universe; that something sweet should soften
it, that there be parts that would play the role of eyes, and that all
things should possess mutual sympathy by their irrational life.[209]
Thus only is the universe one, and thus only is it constituted by a
single harmony. How then could it be denied that all these things might
be signs, resulting from the laws of analogy?
