But what would true objective morality actually be like? Where could it reside external to the minds of humans and other sentient beings? There is a problem with this, as moral standards are felt emotionally, they are connected with empathy, with conscience. Also, a moral standard that wasn't in some way subjective would not need interpreting. It would not be possible to think of a moral position related to that standard and have a subjective position on that standard, as then we are in the situation of subjectivity - if we are in a position to question whether or not something is really wrong, or really right, then we lose the objective aspect of that moral question.
The problem, I suggest, is this - the only way an objective moral value can exist is if it's not possible to have a subjective alternative feeling about it. Objective morality must mean unchallengeable consciences.
Or does it?
