Pascal's wager

In my humanities class today, I talked a bit about Roman architecture.  One of the more famous buildings the Romans built is the Pantheon, the temple of all gods.  In addition to containing statues of a whole bunch of gods, it apparently traditionally contained an altar dedicated to gods as yet unknown.  It occurred to me that this is the result of taking the sort of reasoning involved in Pascal's wager seriously; if we don't know what gods there are, try to make sure none of those we've ever heard of are unhappy with us in case they exist, and to be super safe, try to be nice to gods we've never heard of too.  Of course, it's not clear how to make an unknown god happy, which is the place where the whole program falls apart a bit, but it does perhaps make clear how odd it is that Pascal himself and so many of those who cite him think the way to take no chances is to be Catholic.  Surely that's taking all sorts of chances; the odds have to be better with the earlier Roman way.
