Contra Metaphysical Idealism

[Chas]

You are asking nonsensical questions.
Concepts and ideas exist in minds, not 'out there'.

Right. They are nonsensical questions. When the framework of reality is considered physical, then asking where that framework exists is nonsensical. Where is the universe?

The same goes for asking where ideas are in an idealistic reality. They ARE the reality. Asking where they are doesn't make sense.

In that case there is no operational difference between a physical view and you so-called idealistic view. The difference, however, is that yours adds a layer of explanation that is unnecessary and explains nothing.

Please explain 'magical mechanism'.
Please explain why there needs to be anything 'underlying' reality.

I'm not sponsoring the idea of a magical mechanism. I'm saying that all views of reality, including the physical and idealistc ones, are subject to issues of infinite regression or the problem of uncreated existence.

Well, reality is experience, or at least experiences are the only things that can be known for sure to be real. A physical monist world view posits that there are existent objects, arranged in space and time, which underly our experiences. Does there need to be such an underlying reality? No-- in fact, nobody can prove that there is one. That's the point.

The evidence that the physical reality is there is that we can independently affect it and get the same results. That indicates that there is reality.

Proof? No, evidence.
