I know this is one of my pet peeves, but it's a good pet peeve to have, since far too many people misrepresent the abortion debate as being about when life begins. When life begins is a scientific matter, and anyone who recognizes that should have a hard time seeing the plain meaning of Joe Biden's statement as follows as outright endorsement of relativism about science:
MR. BROKAW: If Senator Obama comes to you and says, "When does life begin? Help me out here, Joe," as a Roman Catholic, what would you say to him
SEN. BIDEN: I'd say, "Look, I know when it begins for me." It's a personal and private issue. For me, as a Roman Catholic, I'm prepared to accept the teachings of my church. But let me tell you. There are an awful lot of people of great confessional faiths--Protestants, Jews, Muslims and others--who have a different view. They believe in God as strongly as I do. They're intensely as religious as I am religious. They believe in their faith and they believe in human life, and they have differing views as to when life--I'm prepared as a matter of faith to accept that life begins at the moment of conception. But that is my judgment. For me to impose that judgment on everyone else who is equally and maybe even more devout than I am seems to me is inappropriate in a pluralistic society. And I know you get the push back, "Well, what about fascism?" Everybody, you know, you going to say fascism's all right? Fascism isn't a matter of faith. No decent religious person thinks fascism is a good idea.
I'm very sure that Biden didn't mean what he said. He surely doesn't think scientific truth is all a matter of what you happen to believe any more than Nancy Pelosi thinks life doesn't really begin at conception when she quotes church fathers against the current Roman Catholic view (thus in effect quoting religion against science, ironic as that is from the highest-ranked (in one measure, anyway) Democrat in the United States. Both of them mean to be talking about moral status and perhaps personhood. But it's not at all clear what exactly he intended to say about it. He obviously couldn't have meant some kind of thoroughgoing moral relativism because of his last statement. What generates the relativist-sounding move is not that it's about moral views, where a moral relativism of some sort then kicks in once you enter moral territory. He both has some notion of what a decent religious person is (which sounds objective, even though it uses a value-laden term 'decent') and some notion that a view has to be held by a decent religious person to count as appropriate in a pluralistic society, which he takes to rule out Hitler's fascism.
What I'm least sure of is what he really thinks about all those religiously held beliefs. When he says he knows when it begins for him, does he want to say that any deeply-held religious belief is true for the person who holds it, in which case there's really no religious truth, just religious feelings? Or does "I know when it begins for me" function as an equivalent expression to "I know when I think it begins". It's a bit awkward to take it that way, but it would be something like "As for me, I know when it begins, but I'm not going to expect others to understand that because it involves faith, and I respect their conflicting religious traditions.
Is that overly charitable? Keep in mind that this is Joe Biden.
