This is in three posts:
Now your position is that no objective morality exists, and that morality is only subjective.
Correct.
This begs the question though from your point of view that if God told you to sacrifice your child, would you?
Wouldn’t you at least immediately begin to rationalize what you would potentially do?
Wouldn’t you therefore be structuring your own argument in your head weighing the possible benefits/negatives of this potential action and what effect it would have on you and others?
There are sometimes tough close calls of morality questions, but isn’t that what we always do?
As another example, do you not murder because you remember that God has this moral commandment, or is it something else?
Without believing in God’s moral laws, isn’t it possible for non-believers today to still live and act morally based upon what you view as God’s moral law? Then doesn’t that prove that we can reason to the same extent of what you think is God’s moral law?
This is to say that morality is solely dependent on what human beings think, ie, there is no independent existing morality.
Correct.
Therefore morality is only the result of socio-biological conditioning, or personal preference. And you try to claim this is sufficient for us to live happily. But it clearly is not.
I wouldn’t say it’s preference, but rather a necessity for what works. Hitler can have preference all day long to have it his way, but that isn’t reason in itself.
My position is that if objective morality does not exist, then it is not objectively wrong to say, round up and exterminate the Jews, rape and kill a little girl, or abuse children.
You used the word
objective twice, each with a different meaning. If we grant for argument that objective reality doesn’t exist in the sense of from God, then it still is wrong objectively in the sense that humans have created the objectiveness that applies to all. Sure, not everyone will believe it is wrong, and they have their opinion (subjective view).
Such things may be taboo in the sense that society has determined them to be so, but this does not show that they are really wrong.
You are already assuming again that God has set objective morals by saying
really wrong. What is really wrong is what we can reason to be wrong. Everyone can still have opinions as they do in everything.
I find this position not only irrational, but frankly offensive.
I am not trying to offend, but only reason with you. Sometimes it’s hard to believe that a child raper who never got caught will eventually die, perhaps without justice. But I’m interested in what’s true, not wishful thinking. That’s why we come together to try and give justice to those who may one day fight for ours. We have reasoned with each other that this is right because it’s reasoned so, and this is wrong because of reasoning as well.
First, you cannot set an objective morality.
Not in the sense that you are assuming again.
If morality is something we invent and agree on, then it is purely subjective.
Correct. I just use the word “objective” meaning applies to all or everything.
Second, you are mistaken that science provides a basis for morality or progress. Science tells us what “is”; it does not tell us what “ought” to be.
This is true on pure definition, but not an analytical level. We can run two experiments each with different levels of morality. The results simply show us what happened. It doesn’t pick one over the other. In fact, we can run thousands of experiments simultaneously daily, each showing different results. Now we can all look at them and simply see which is better, with our assumption that we do not want to be in distress, as that goes against instinct. We choose and debate what it “ought” to be based on the resuls.
For instance, it is a scientific fact (history is very much a science) that the Romans exposed infant girls in enormous numbers,
Yes, science says this happened. But you missed the part where science said it didn’t sustain itself and instead collapsed.
and that the behavior we call rape happens in the animal kingdom.
Rape is rare in the animal kingdom. Usually a male will not try to mate with a female unless she is in season, and she will then accept him if she feels he is a good mate. If she doesn’t want him - for example, he seems weak, and she doesn’t want his genes for her offspring - she will reject him, and there is usually no way he can force her.
One animal that commonly practices rape is the orang-utan (one of our closest relatives, interestingly). It’s thought that around half of all orang-utan births are the result of rape. This happens because orang-utans are solitary, and when a female comes into heat a young or subordinate male often finds her before any other male. The female does not want him as a mate - she wants a fully-grown, dominant male who will pass on good genes to her offspring, having proved he is a good survivor - but he is stronger than she is and, having arms and hands, is able to hold her down and force her to mate with him.
It is what it is. I don’t like it, and we can fight to change things. Nowadays we realize we are generally better off to fight with our ideas, given that if we don’t win, we still have a fairly good life, rather than battle living or dying for it.
