"There is always war among Them"

Gratillonius gives Mithras a bull on Lir's cliff under Taranis' sky during a thunderstorm and laughs at the Ysan Gods. One of his followers knows that:

"'Other Gods are angry.'"
-Poul and Karen Anderson, Dahut, Chapter VIII, section 3, p. 165.

-but another replies:

"'There is always war among Them.'" (ibid.)

"'...the common folk are with Grallon...is he not their wonderful King, on whose reign fortune has always smiled?'" (VII, section 4, p. 171)

For a politician, it is often enough to have the common people on his side, although not in the long run if his policies are economically or ecologically ruinous. Defiance of a literally existent Sea God is ecologically ruinous. James Blish's black magician says:

"'...the sciences don't accept that some of the forces of nature are Persons. Well, but some of them are. And without dealing with those Persons I shall never know any of the things I want to know.'"
-James Blish, After Such Knowledge (London, 1991), p. 365.

I find parallels between The King Of Ys and After Such Knowledge.

I wanted to find that statement by Theron Ware but had to reread a chunk of the book to find it but did so with pleasure.
