This is really great except that Greene can't write atheists. These atheists are barely even agnostics, I mean they still pray even though they pray to “the God I don't believe in.” I presume what happened is that Greene believed that whatever he was before he converted to Catholicism (undecided but monotheistic, I'm guessing) is what atheists really believe, which is obviously not accurate. These atheists are not believable atheists because they at least acknowledge that there is a god, though they claim they don't believe. That's not what I understand atheism to be. This is a minor quibble. Everything else about this is just classic and right up there with his best work. There are the usual great lines, and usual great insights into the human condition.
