But they also show whom they would have Jove (who is also called Jupiter) understood to be. He is the god, say they, who has the power of the causes by which anything comes to be in the world. And how great a thing this is, that most noble verse of Virgil testifies:
“Happy is he who has learned the causes of things.”
But why is Janus preferred to him? Let that most acute and most learned man answer us this question. “Because,” says he, “Janus has dominion over first things, Jupiter over highest things. Therefore Jupiter is deservedly held to be the king of all things; for highest things are better than first things: for although first things precede in time, highest things excel by dignity.”
Now this would have been rightly said had the first parts of things which are done been distinguished from the highest parts; as, for instance, it is the beginning of a thing done to set out, the highest part to arrive. The commenc-
ing to learn is the first part of a thing begun, the acquirement of knowledge is the highest part. And so of all things: the beginnings are first, the ends highest. This matter, however, has been already discussed in connection with Janus and Terminus. But the causes which are attributed to Jupiter are things effecting, not things effected; and it is impossible for them to be prevented in time by things which are made or done, or by the beginnings of such things; for the thing which makes is always prior to the thing which is made. There- fore, though the beginnings of things which are made or done pertain to Janus, they are nevertheless not prior to the efficient causes which they attribute to Jupiter. For as nothing takes place without being preceded by an efficient cause, so without an efficient cause nothing begins to take place. Verily, if the people call this god Jupiter, in whose power are all the causes of all natures which have been made, and of all natural things, and worship him with such insults and infamous criminations, they are guilty of more shocking sacrilege than if they should totally deny the existence of any god. It would therefore be better for them to call some other god by the name of Jupiter–some one worthy of base and criminal honors; substituting instead of Jupiter some vain fiction (as Saturn is said to have had a stone given to him to devour instead of his son,) which they might make the subject of their blasphemies, rather than speak of that god as both thundering and committing adultery,–ruling the whole world, and laying himself out for the commission of so many licentious acts,–having in his power nature and the highest causes of all natural things, but not having his own causes good.
