The intelligent beings in these regions should therefore not be surprised if they observe that their locality in the universe satisfies the conditions that are necessary for their existence. It is a bit like a rich person living in a wealthy neighborhood not seeing any poverty.

Suppose we've chosen the wrong god. Every time we go to church we're just making him madder and madder.

I do not believe in the creed professed by the Jewish Church, by the Roman Church, by the Greek Church, by the Turkish (Muslim) Church, by the Protestant Church, nor by any Church that I know of. My own mind is my own Church.
