Saletan:
I think it's bad because the fetus is of us and is becoming us. It's not a person, but it's on the way to becoming a person, and the longer it develops, the more I recoil at the idea of killing it. Most people, according to polls, think the same way.
Pollit:
You ask what my own view of abortion is. I think the meaning of abortion is what the woman says it is: For a woman who wants a child but can't have this one it can be sad; for a woman who doesn't want a baby, it can feel like a huge relief, like having your whole life given back to you. Negative feelings—the sense of the road not taken, that maybe you would have wanted to take had life been different, the feeling that you chose yourself instead of the baby-to-be and maybe that means you are not a good woman, the feeling that you messed up somehow—are often confused with morality, but they are not the same. Morality has to do with rights and duties and obligations between people. So, no: I do not think terminating a pregnancy is wrong. A potential person is not a person, any more than an acorn is an oak tree. I don't think women should have to give birth just because a sperm met an egg. I think women have the right to consult their own wishes, needs, and capacities and produce only loved, wanted children they can care for—or even no children at all. I think we would all be better off as a society if we respected women's ability to make these decisions for themselves and concentrated on caring well for the born. There is certainly enough work there to keep us all very busy.
I think the word count says it all here. Saletan makes a coherent argument and isn't afraid of the moral consequences of his position. Pollit can't quite accept the reality of her position and has to throw up a cloud of smoke to obscure the answer. I think they're both wrong on lots of points, but Saletan seems to win this argument hands down.
