What does philosophy have to say about the role of emotion relative to ethics? It seems clear that emotion cannot be relied upon to produce consistently accurate ethical judgments, yet it also seems that emotion is a motivator for people's actions (which must be considered in the context of ethics). Further, emotion seems to be used as an "acid test" of sorts for ethical judgments (i.e. things that are ethical should "feel" or "seem" right). These are three examples of the way emotion and ethics interact, but I'm interested in perspectives on what their relationship should be, in the interest of making optimal ethical choices.
