In 1997, former chairman of the President's council on bioethics, advanced the idea that “in crucial cases…repugnance is the emotional expression of deep wisdom, beyond reason’s power to fully articulate…” (The New Republic).
I suspect that few ethicists working today take this position at face value. Still, there do appear to be tangible concepts that are commonly defended on the basis of intuition alone - human dignity is one such example.
Do those who would reject any role for emotion and intuition in moral judgment throw the metaphorical baby out with the repugnant bathwater (cf. Jones, The depths of disgust, Nature, 2007)?
