It's like time, or value. these concepts have no meaning out side of the mind, and they can be different from one mind to the next.
Thought experiment time.
Let's say we're all robots. We don't have minds. We just have our programming. We don't contemplate the intricacies of moral actions and duties and values and all that, we simply do as programmed(we'll say all programmers are now dead, just to simplify things.)
Are you saying no time passes? Are you saying that the objective insertion of numbers into X(which would be a value) in our programming wouldn't really be there?
Sure, morals can differ from person to person, but that doesn't undermine the objectivity involved in what is right and what is wrong.
Something we can clearly see within people is the desire to flourish. Becoming better, healthier, happier, ore satisfied, these things are a universal desire of people. Can we not OBJECTIVELY determine the best ways to go about achieving these goals? Subjective though the goals may be?
If, say, I value human life. Would it not be objectively true, given that value, that running over random people with my car would be bad?
