People sometimes argue back and forth about whether religious belief is a good thing, because it induces believers to be moral or charitable. In a big-picture sense, I think arguments of this form completely miss the point; beliefs should be judged on whether they are correct or incorrect, not on whether they cause people to do good or bad things. (If the belief is not correct, but it makes people do something good, can we say they've been tricked into acting that way?) Certainly, nobody is going to convince me to believe something if they admit that it's false, but it would be good for me to believe -- recommendations of that sort are usually aimed at other people, not the one handing them out. Besides which, as a matter of historical record it's pretty clear that religion has led people to do some really good things and also led people to do some really bad things, and trying to weigh the effects on some imaginary scales seems just hopeless. Or at least, an interesting and possibly never-ending source of discussion for sociologists and historians of religion, but fortunately orthogonal to questions of the truth or falsity of religious claims. Still, I confess to being a bit amused by the news that, in the last years of her life, Mother Teresa didn't believe in God. (Via Cynical-C.) Letters that she wrote have now been released as part of a book project, and they are shot through with serious doubts.
Shortly after beginning work in Calcutta's slums, the spirit left Mother Teresa. "Where is my faith?" she wrote. "Even deep down... there is nothing but emptiness and darkness... If there be God — please forgive me." Eight years later, she was still looking to reclaim her lost faith. "Such deep longing for God... Repulsed, empty, no faith, no love, no zeal," she said. As her fame increased, her faith refused to return. Her smile, she said, was a mask. "What do I labor for?" she asked in one letter. "If there be no God, there can be no soul. If there be no soul then, Jesus, You also are not true."
I'm not someone who has strong feelings about Mother Teresa either way, and it seems sad that her doubts put her in such apparent torment. (To the extent that these letters paint a reliable picture at all, of course.) And, in the department of "things that are perfectly obvious but must nevertheless be said explicitly because it's the internet," this is only one individual case, from which no grand conclusions should be drawn. Except the obvious: motivations for altruistic and charitable behavior can be very complicated. We should keep them separate from our attempts to understand how the universe works.
