[Serious] Moral Obligations toward Possible Worlds

[Angrboda]

I don't know whether moral truths themselves are dependent upon intuition, but determining whether something is morally true or not seems to rest only on intuitions.  Some people will suggest that such and such maxim is obviously objectively true, but it always resolves into it being obviously true to them, but not to everybody else.  So if there is a moral obligation towards future generations, we don't have a reliably rational way of determining that.  It's possible that the majority of people might find that it agrees with their intuitions, but is a majority enough to conclude that something is probably true?  At one time a majority thought there was nothing wrong with slavery.  Our morals appear to inescapably rest upon intuition, and intuition is a guide of questionable value.
