What is it, and why is('nt) it a useful idea?
Interesting question.
As I understand it, based partly on personal observation/opinion, and partly on dictionary definitions (see sources below), morals are the codes of conduct a society, culture, or individual uses to determine what's right and wrong. I would suppose, then, that "moral responsibility" would have at its core a sense of being true to whatever moral code they have learned in life.
Where this is useful is in helping a society function without everybody killing each other, and in helping an individual relate to others in his society. CM makes a good point in mentioning that part of moral responsibility means that people hold both themselves and others accountable for their actions - in general I'd say it holds a society together and preserves it, if people are willing to do this.
The word "moral" ultimately derives from the Latin word
mos, moris, which means "custom". This is, I think, something that people forget: morals are based in localized customs. I bring this up because where moral responsibility isn't useful is in comparing one culture to another (or even differing groups within a culture). What one group finds moral, another may not. Question then arises as to whose morality applies.
I can agree with somasoma too, though, that the idea of moral responsibility can be used to manipulate the masses. Especially since morality is all about good vs. bad. Who wants to appear bad?
In saying all this I'm kind of curious about the word "useful" though - useful to what? To whom? A society or individual?
Well, okay, I'm rambling now. Thanks for reading.
