This don't make sense.
It's saying that Moral objectivism is the idea that there is an objective morality, hence most philosophers consider it to be objective morality.
LOL, Tiberius, when philosophers call objective moral values and duties moral facts, they use the terms interchangeably. Its just a shorter way of saying it. That is all that statement means. Its like a geography teacher saying to her class:
"It is objectively true that Canberra is the capital of Australia."
"She could also say:
"It is a fact that Canberra is the capital of Australia."
It is a distinction without a difference. Shes sayin the same thing. Understand now?
2 + 1 = 3 is externally testable. How can I test externally if it is wrong to smack a disobedient child?
2+1=3 is known to us via our reasoning capacties which take place in our brains and is void of a moral context.
Asking if smacking a disobedient child is wrong, is a question regarding moral duty or moral obligation and specifically, with an emphasis on applied ethics or how we should discipline disobedient children. Some say they should be placed in timeout, some say they should be spanked on the bottom or on the back of the hand. Some people even think a good smack across the face is best. This is a question of what is the
best means of disciplining a child.
What is not in question is that
disobedient children should be disciplined. This is the
underlying objective duty that dictates that children's disobedience should not be rewarded, but reprimanded.
It is true for all people, in all places, and all times, regardless of their own opinions, that disobedient children should be
in some way disciplined. To not discipline a disobedient child would be seen as a failure of the parent's duty to properly raise a child.
if it is possible that our ideas about morality are wrong, how can we claim it is objective?
The same way we can objectively claim that the external world is real and that it was not created five minutes ago with the appearance of age.
It is possible that we are wrong in saying that the external world is real and that it has existed for eons, but does that mean that we cannot claim that it is objectively true that the external world is real?
Of course not!
By what testing procedure can I determine if something is OBJECTIVELY wrong?
How do you determine if anything is wrong at all? Forget the word objective and just think about that question. How do you determine if anything is wrong?
All you have been able to say is that I should use my own conscience, but that would seem to indicate a SUBJECTIVE, not objective morality.
I did not say that you should use your own conscience. I said we intuitively apprehend moral values and duties. Some call it conscience some call it intuition. The words refer to that process of reasoning by which we make moral judgments.
You seem to think that just because individuals are the ones who make moral judgments, that therefore moral values and duties themselves are subjective.
This is the same as saying that since scientists used their own individual minds to assimilate the evidence for the shape of the earth, that therefore the earth's shape was subjective?
But that does not even make sense. How can the world in which we live be said to have a subjective shape? That does not even make sense. The world is either flat or round. The earth's shape is an objective fact independent of scientist's minds. Scientist's discovered that the earth was round. They did not make it round by thinking it was round!
See the difference?
