Don't dismiss what you're not understanding as sophistry.
That is to close yourself off from ever understanding it.
Imagine, if you can, that there is a giant ball hovering in our atmosphere.
Imagine that this is the objective reality, that there really is this giant ball.
This is the objective reality for everyone, and every thing.
Now, for some people that ball may be completely obscured from their view by a mountain.
They can not see the ball, they have no idea (other than what people tell them) that there is a ball.
So their
subjective view is that there is no ball.
For those that can see the ball, they will also have a subjective view of the ball, depending upon their own position/perspective etc.
But the objective reality for all these people is that there is a ball.
Now, imagine, if you can, a world where there is no giant ball hovering in the atmosphere.
This is now the objective reality.
However, some people may be convinced that there is a ball, and that they can see it.
This is their
subjective view.
If we don't know what the objective reality is, i.e. we don't know whether there is a ball in the atmosphere, then our position on whether there is one can only be a subjective view, which may or may not match the objective reality.
This is not sophistry, but something you really should understand if you're to meaningfully discuss whether morals are subjective or objective.
Objective reality is what it is; it is the same for everyone once you strip away all personal bias, perspective, position etc - which is what makes it objective.
Subjective reality is what is "true for us", i.e. it is the interpretation of the objective reality according to our own personal perspective, bias, situation etc.
Subjective reality is all we have in the absence of knowing what the objective reality is.
If I posit that unicorns exist, would you consider that a legitimate exercise in objectivity?
??? "Exercise in objectivity"?
If unicorns exist, that is the objective reality.
If unicorns don't exist, that is the objective reality.
There is no exercise involved.
In the absence of absolute proof or knowledge of the objective reality, if you believe that they exist then that is your subjective reality, which may or may not correspond to the objective reality.
Similarly if you believe that they don't exist, then that is your subjective view.
If you don't know what the objective reality is, you can only ever have a subjective viewpoint of it.
The point is not if there is a question if an objective God exists.
The point is that there is a statement "God exists" but it is not supported by any evidence.
I think you're confusing the issue.
This isn't about whether or not God exists, nor is it about evidence of whether God exists or not, but about whether morals are objective or subjective (and more recently from there into what is objective or subjective with regards reality).
I am not concerned about whether God exists or not.
However, one argument for objective morals is that they are God-given, that they are (or should be) the same for all, irrespective of our own personal (i.e. subjective) view on the matter.
No one has been able to even describe God, except in some vague platitudes shrouded in mystery and magic.
Can a Supernatural being even objectively exist in our universe?
That's not the point.
The point is that IF God
objectively exists then that is the objective reality for us all, whether we are aware of it or not.
Is that not why we call it "faith" and "belief"? It certainly is not "knowledge".
Belief in something is a subjective view that may or may not match objective reality.
It is a subjective assumption, like belief in Santa Claus. There is no objectivity involved. It's sophistry.
Unless you are of the viewpoint that there is no objective reality, and that everything is subjective, then there IS objectivity involved.
Our belief (subjective view) on the matter may or may not match the objective reality of it.
Objective morals (to bring it back to the matter at hand) are morals that are universal (to humans, being the only species we know to whom the concept has meaning), that are the result of the way the universe operates, or handed to us by God, or whatever other reason one might argue for.
Just because a rock has no morals does not make morals therefore subjective.
Just because a rock is not human does not make the existence of humans subjective.
