My point was, all of those long dialectical arguments culminated in the idea that, therefore, the answer must be a God. They all fail, because they don't disprove other possible causes, the author just picked the one most comforting to him.

It's the same reason that before we understood the physics of lightning, people said "It must be Zeus! Zeus throwing lightning bolts, that's the explanation!"

Nope. Didn't you read what I posted?

"... and this everyone understands to be God."

"... to which everyone gives the name of God."

"This all men speak of as God."

"... and this we call God."

"... and this being we call God."

St. Thomas is saying that the descriptions given are descriptions of what we call God.

The alternative to this is to say that they are not descriptions of what we call God. This requires (a) providing the alternative description of what we call God, (b) providing the alternative naming of these five things as some other thing(s).

If you wish to take up that challenege, go ahead and do so here and now. Don't sit around and pretend that Occam did it for you.
