I am reading some extracts from Hume's "treaties" and some papers which have been released on them, but I still do not fully understand Hume's position on moral judgement.
Hume states that moral judgement is based solely on passions, or at least that reason alone is not sufficient for moral judgement. However, what I don't fully understand is this. Given that a person witnesses an action, their reaction (ie: declaring it moral/immoral) should be based on whether the impresson such action has on them produces pain or pleasure.
However, it seems to me that in some instances Hume claims that the impression made by the judgement society will give to the individual's judgement (ie: "what will people think about person X if they support a certain position) will be more important than what the person really feels about an event. For example, a person may support Hitler in the Holocaust (I know, I'm not particularly imaginative in my examples, but at least I get to make my point :) ), but as this position would be condemned by the majority of people, they will be drawn to feel otherwise about it.
