Absolute moral rules can be discovered through logical deduction.
Can you elaborate?
I don't believe that's possible unless you take an axiomatic approach which would obviously be a moral relativist approach since we can just disagree on the choice of axioms themselves and prevent any deduction.
How do you overcome the is-ought problem?
Yet you, and every other human still engage in moral behaviors.
Just human? I mean, sure do, but we're leaving out a huge array of animals who also engage in rudimentary moral behavior.
You have some prescriptive intuition buried deep inside you.
Of course, we evolved to be social animals did we not? What else would you expect but inate instinctual "rules" when they'd lead to a clearly fitter society.
The ability to describe the components, inputs and outputs of that intuition is the entire conversation.
Right, and just like the variation in genetic material this variation in inputs and outputs that we all have which are wholly unique to us as individuals and while remarkably similar to others raised in similar environments, also remarkably unique in subtle ways.
I agree this is the entire conversation. And the obviousness of this fact, that moral expression is subtly unique to each individual, is the ultimate answer to the question.
If you are raised in a subjectively different environment, then the rules you learn to behave by will be subjective to that environment.
"Morality is subjective" is the inevitable conclusion of a secular, empiricalistic worldview.
Essentially, now that we are in a scientific world disagreement is resolved through experiment.
Disagreement not resolvable through experiment is removed from the realm of science, and is called falsifiable and is seen as subjective.
If you and I disagree, there are no scientific tests we can run to resolve moral issues.
And since we can't point to a God or objective moral laws, it doesn't even matter if one theoretically exists because it's inaccessible and infalsifiable. Effectively it doesn't exist for us.
Both of us are following different moral standards, the "rules" in your head are not the same rules that I'm subjective to.
You're morals are subjective to your experience, it simply is a fact.
Then again, isn't that what people used to do with StackOverflow?
Yes, one of the major issues with StackOverflow that answerers complained about a lot was the "XY problem.".
https://meta.stackexchange.com/questions/66377/what-is-the-xy-problem
Where you're trying to do X, but because you're inexperienced you erroneously decide Y must be the solution even though it is a dead end, and then ask people how to do Y instead of X.
ChatGPT drives that problem up to 11 because it has no problems enabling you to focusing on Y far longer than you should be.
Just because its easy to get a bunch of humans to agree say murder is wrong, doesn't mean you can call that objective.
The reason humans and ants differ so much in morality is because of the difference in the subjective experience of being a person versus being an ant.
If morality is subjective, you'd expect creatures with similar subjective experiences to agree with each other.
You'd expect one subjective blob of rules to conform to human biology/sociology and a separate blob of subjective rules to apply to antkind with no real way to interface between the two.
