I just read a very well thought out article on FR about Terri's case. It's by ethicist Eric Cohen. It's a tad lengthy but an easy read and one of the best articles I have read for continuing to give Terri food and water. For anyone interested, here it is:

That is truly a profound article. It's one flaw, however, is that the author assumes that the decision about Terri's wishes was based on conversations with Michael, and we know that is not true. I also think it's a little weak on the fact that people can make their wishes known verbally; I'm not sure the author would ever accept verbal statements concerning one's wishes; he even seems to be advocating ignoring living wills. But he raises many thoughtful questions.
