the entire contro is apparently 'way beyond me
I don't think it is, Dale. Maybe this will help
The guy talks about:
....The belief that truth, and reality, are whatever we choose to believe them to be and can force on our fellows.
If you believe that, then you might be inclined to also believe that SR reflects "reality." This is a solipsistic or subjectivst viewpoint.
He then says:
Whether we can know, sense, measure, or understand some aspect of reality or not it still, nevertheless, is. Its being does not depend on our consent nor our observation nor our understanding of it, nor even our own being. We are not gods.
If you believe that, and consistently apply that belief, then you will reject SR as being consistent with "objective reality." This is the objective view, also known as "philosophical realism."
The objectivist says that when we perceive something there are two entitites involved: The observer (the "subject") and the thing being observed (the "object"). This is where the distinction between subject and object come into the terminology.
The solipsist says there is no "object," and that only the "subject" (the observer, i.e., the person) exists.
