You say that moral values cannot be the values of just any old subject, such as you and I, because we might disagree, and that would make moral values subjective or contingent in a bad way — Janus
That is absolutely not the argument I made! I think moral values ARE contingent.
Yes, moral values are not the values of just anyone, but just one person - the person whose values they are. A person we can call Reason.
But my basis for that claim is that it is manifest to reason that if you or I value something it is not of necessity thereby morally valuable. Thus, our reason - our faculties of reason - tell us that we ourselves are not the ones whose moral values our reason gives us insight into. That is, our faculty of reason is not another faculty of introspection.
It has nothing to do with the contingency moral values would have if they are the values of a subject. My evidence that my values are not moral values is that my reason tells me that they are not. I may be quite sure I value something, yet that does not settle the matter of whether it is morally valuable. I accept that though I may value xing, that does not entail that it is morally valuable. Again, I accept this because it is manifest to reason. both mine and yours and virtually everyone else who isn't crazy or in the grips of a theory.
I think this is an ongoing problem - rather than looking at the argument I have actually given, you project quite different ones onto me and then, when what I say does not seem consistent with the view you've projected onto me, you insist I am not being clear or making sense!
Anyway,
I have allowed for Reason changing her mind when circumstances demand, but if she were able to simply change her mind even though circumstances have not changed, then she could not be a reliable guide to moral values, unless you allow that they are merely subjective and contingent in a bad way. — Janus
Again, I think moral values ARE contingent. Most contemporary moral philosophers - indeed, most moral philosophers full stop - think they're necessary. Hence why they reject ALL subjectivist views on the basis of Euthyphro-based concerns.
I am a subjectivist. I think moral values and norms are contingent. I reject other kinds of subjectivist view - those that identify moral values with our own - not on the grounds that this would make moral values and norms contingent. No, I reject those views because they are self-evidently false upon reflection. I reject them because if I value something, it is manifestly not thereby made morally valuable - not of necessity, anyway.
You seem fundamentally not to understand the view my arguments have entailed. For you say that Reason would not be a reliable guide to moral value. Er, but moral values ARE her values. So how on earth - how on earth - could she be anything other than the most reliable guide to them?
Who is the most reliable guide to what Bartricks Potter values? Why, Bartricks Potter!
Who is the most reliable guide to what Hugh values? Why Hugh of course!
Who is the most reliable guide to what Reason values? Why Reason of course.
How has reason attempted to tell us about what she values - why she's given us a faculty of reason. So, if you want to find out what Reason values, consult your reason and the reason of others.
Now nothing I have said there engages with the Euthyphro. Hence why I don't see how what you're saying engages with it.
Those who think the Euthyphro criticism is a good one - so, you know, the vast bulk of moral theorists - think it is a good one because they think moral truths are necessary truths.
I think they're wrong about that. But my first point is that unless you agree that moral truths are necessary truths, then you can't use the Euthyphro to try and challenge my view - for you'd be committing theoretical suicide. And I am also pointing out that this is actually true whether you're a subjectivist or an objectivist about morality.
So my first point - my first step - is to wipe the smile off everyone who thinks the Euthyphro is a damning criticism by pointing out that it applies to objectivists and subjectivists alike.
