I didn't mention God. — Bartricks
1. If moral values are objective, then moral values with be contingent, not necessary
2. Moral values are necessary, not contingent
3. therefore, moral values are not objective — Bartricks
It appears self-evident to the reason of most that moral truths are necessary, not contingent. How else do you explain why the Euthyphro is considered by virtually all contemporary moral philosophers to be such a damning criticism of subjectivist views??? — Bartricks
I am using 'necessary' to mean 'cannot not be the case'. — Bartricks
You mention the Platonic form of the good - okay, so if this strange obelisk values things (a notion I can make no sense of whatsoever), why is it the case that it could not disvalue the things it values? — Bartricks
That's not what I said about 'the good", nor is it what Plato said about 'the good". — Metaphysician Undercover
No, it is exactly how it is used in moral philosophy. You're the one using it incorrectly. — Bartricks
Or do you think that moral values are not invariable across time and space?
if so, what do you do with all those widely corroborated rational intuitions that represent it to be? Just reject them? — Bartricks
If two worlds are identical in all non-moral respects, then necessarily they are identical in all moral respects? — Bartricks
That criticism is that if moral norms and values are the prescriptions and values of a subject (be they a god, gods or us) then they would not be immutable. They could vary over time.
Yet, in Plato's day as today, moral norms and values appear to be fixed. They are represented to be by our reason. Hence a problem. — Bartricks
Just engage with the actual criticism. — Bartricks
If two worlds are identical in all non-moral respects, then necessarily they are identical in all moral respects? — Bartricks
Now imagine there is another planet exactly like this one - I mean, exactly like it in every physical respect. — Bartricks
