If "SR" is "special relativity" then I can truthfully say that
I've heard of it.

I don't believe I've ever had a problem understanding what
you've said. "Words can mean different things" isn't much
of a concept. The thing you often don't seem to get is that
when we say "1+1=2" we don't mean " '1+1=2' ".

Thanks for your patience, Fred. I apologize if I seemed overly
aggressive here. It's hard not to get caught up in all this. Instead
of directing it at you, I should have said, "It seems THE AUTHOR is
sneaking... THE AUTHOR posits...." etc.

Best regards,

It's polysemy, and it's the prime confusion causer in our civilization.

Even if I accept that (I'm not expressing an opinion either way)
it's still not a terribly *complex* concept. The number of different
instances of it, and the scope of the consequences might be
enormous but it's still a simple idea.

Actually I've never argued "Words can mean different things" is a
complex concept, and certainly not 100+ years after SR! The question
I had and which you've not indicated a clear answer is: would you
agree or not agree that the truth of the mathematical statement,e.g,
"4+5=9" is a relative truth?
