No. How valid an idea is depends on the idea and its merrits.
Merrits are subjective
Like "evidence" and "explanatory power" - if the goal of the comparasion is to see which idea is the most accurate.
Accurate is different between the objective, inter-subjective and individually subjective.
When it comes to ideas about how objective reality works, empirical evidence seems the only standard that applies for the conclusion to be trustworthy.
All of the world is not objective.
I get the idea. You think opinions are more relevant then facts and evidence.
If not, then you are again being very confusing. Perhaps you are again using words in ways that nobody else uses them.
I think that the objective is relevant if it is objective. I don't think that the objective is relevant if what is going on is subjective
No, I'm not. I'm a software engineer and a drummer.
So in part STEM
I was talking about the validity of ideas about how things in reality (the external world) work.
I have no idea what you are talking about.
And I am talking about that all ideas about what the external word is, are internal in part.
[/QUOTE]I asked you specifically the following questions, after you continued to argue over it:
1. do you agree that "true"/"accurate" means those things that are proper reflections of reality?[/QUOTE]
No, there are other versions of true and all of the world is not external.
2. if yes, how do you test how "true" or "accurate" a statement about reality is, if not by testing it against reality, which would yield evidence pro or con the idea?
I use coherence, not correspondence for truth.
[/QUOTE]3. if no, then I have no clue what you mean when you use the words "true" or "accurat" and in that case, I'm going to ask you to define what you mean by those words when you use them. What is "true", if not those things that correspond to reality?[/QUOTE]
Coherence as broadly as an internal model of how to fit personal experiences together and make sense of that.
I do that use words like "external world" and I consider you a part of the external world, but my reasons are internal.
I am an epistemological solipsist and that is not the same as an ontological solipsist.
We are discussing objective claims about the external world
No, we are not. We are discussing different models of how to understand the internal and external and combine those 2.
You have one internal model of truth and I have another.
