What did Bernard Williams mean by ‘one thought too many’?
A book on care ethics I borrowed keeps quoting Bernard Williams's phrase "one thought too many", and I think I understand it but I want to be sure.
As I understand the case: a man can save only one of two drowning people, and one of them is his wife. A moral philosopher might say he is permitted to save his wife, because some impartial principle allows people to favour their spouses. Williams says that if the man thinks "that's my wife, and in situations like this it is permissible to save one's wife", he has had one thought too many. It should be enough that it's his wife.
My questions:
- Is Williams saying that impartial moral theories get the wrong answer, or the right answer for the wrong reason?
- Was he a care ethicist? The book seems to treat him as one.
- Is there a good reply from the impartial side? It seems obvious to me that I don't consult a principle before picking up my own child, but maybe that's just how it feels.
