OK, well I think we are just repeatedly going over the same old ground now.
However, if we get back to what I think was the issue behind the original opening post, namely that William Lane Craig claims that humans show not just morality, but what he calls "objective" morality, by which he means (afaik) that humans alone & apart from any other animals, have morality which is innate and which they are always born with. And in particular he says the "fact" that human morality is "objective" is proof of the existence of God, because that is the only way in which the objective morals could be present in humans.
Whether or not you agree with what WLC says, you seem to be claiming (a)that morality in humans could be objective in that same sense of being somehow automatic in all humans from birth, and not something learned or developed through evolutionary processes, and (b) that the only way to understand such statements about objective morality is through philosophy and not through any evidence-based scientific studies.
I don't think the highlighted part is correct.
I don't regard the fact that we all feel something like morality as being a reason to think that morality is objective and true. After all, we all are born with tendencies to certain fallacies of reasoning, too, and I don't conclude that therefore these fallacies are objective and true.
As well, I don't know if humans are born with an innate sense of a moral code, or whether this is better explained by socialization (or, likely, both).
I agree that science doesn't settle the objectivity question (not even Pup's argument is purely scientific, I think) but of course it could settle whether these feelings are universal and innate.
If that is what you are saying then I completely disagree with you. And I don't think you have any evidence at all of either any objective nature for whatever traits you call "morality", or any evidence to show that philosophy is even any use whatsoever in detecting and confirming any objectivity of morals, and far less that philosophy is capable of doing that where science is not.
I haven't claimed any evidence that morality is objective. I've repeatedly said it's a hard question. Philosophers have discussed it a long time, made a few tentative conclusions here or there and managed to focus the problem, but I agree that there's a real question whether philosophy can settle this issue.
Philosophy simply hasn't the greatly successful methods of science. There are few reasons for that, but the fact that I say a problem isn't appropriately dealt with by science doesn't mean that I expect a conclusive solution by philosophy. Philosophy is, frankly, characterized by asking many of the same questions for centuries, although deriving new ways of looking at those questions.
I'm sure this is one reason people dismiss philosophy, and I don't blame them. As it happens, I'm interested in these questions and the arguments that people raise.
Afaik, the claim of morals as objective, is only that, i.e. just an un-evidenecd claim. And afaik there is no evidence at all to show that philosophy has, or even ever could, discover any objective existing feature as the basis or cause of human "objective" morals.
However, in contrast to that, you could certainly make a scientific study of what anyone such as WLC or yourself means when they talk about "morality", and in particular what evidence they have for saying that the morality is objective in any sense of being an innate feature specific to homo sapiens.
Right! Science can discover descriptive truths about humans and their moral beliefs. I've never denied that.
The question is whether science can ever discover that these beliefs do not and cannot correspond to objective principles. And I think the answer is "no". I think that even Pup's argument will not suffice to do this.
So far from philosophy being the only game-in-town by which to understand so-called "objective morality", I think philosophy is actually quite useless as a means of ever discovering and explaining the physically existing nature of any such traits as "morals", let alone "objective morals". And that in fact, as we have found with virtually every other conceivable claim of anything that is actually said to really exist, the only credible way to investigate such claims is through objective evidence-based science.
But you can only do that (i.e. investigate and explain what is really meant when people use terms like "morality" and claim "objective morality"), if you first have a clear properly defined explanation of what morality is supposed to be. If you cannot even describe clearly what it is you are talking about, then there is nothing actually to investigate at all beyond empty ill-defined words and claims.
Suppose I can't define Bingkauh, but I know it's a sport. I don't know which sport, what distinguishes it from other sports, etc.
That's enough for me to know that the Opera Review won't include reports on Bingkauh, because the Opera Review doesn't include sports.
Similarly, if the content of morality is practical norms, though I am at pains to discuss which such norms are moral and which not, and if I know that science aims at description, then I know that science won't settle questions of morality.
(Pup's recent argument is causing me to think about how everything fits together, and I suspect that I still will end up siding with the claim above, but I must think about it.)
