We as a society decide what morals are correct- which means that they are subjective- not objective.
Human life? Many societies- perhaps most societies- in human history- put less value on human life than we do now.
If any morals were 'objective' then there would be some way to 'prove' that that specific moral was correct. So how do you prove that a moral is objectively correct?
So, when it comes to things like this, I think one needs to look at all the arguments, weigh the evidence… and decide which one makes more sense and is more logical. I’ve put a lot of thought into this, and the view that morality is subjective results in lots of contradictions and absurdities. I firmly believe that morality is objective..
Well that is your subjective opinion.
An objective truth is something that can be measured and can be proven- at least that is what I understand an objective truth to be.
2+2 = 4.
The sunrise on Earth will be to the east.
A subjective truth is what cannot be measured- and cannot be agreed upon by everyone.
Certainly you and I think that slavery is wrong. But for much of human history- many societies did not.
Our societies morals- changed- improved- so that we came to see slavery as morally wrong.
And then our laws changed to reflect that.
Just as some societies found some kinds of homosexuality morally wrong- and even killed homosexuals because of it.
I can see that you have some desire for a discussion of moral absolutes- but I am not much of an absolutist.
I know what I consider to be wrong- and I know why we have laws preventing much of what I consider to be wrong- while we also have laws I don't agree with- and also allow things I consider to be morally wrong.
But that is all subjective- which is why we as Americans disagree with many of these things/
