Mark,
I get you clearer now,,you and James Thomas should talk he has similar ideas.
I think you could be right,,its all concepts,,there is not any truth,,only what we conceptualize as truth,,which when you get to the basics of it,, is not "absolute" but merely concepts. We speak in metaphor and we think in metaphor they are not what is real,,no one can point to what is real,,they can only point to what is conceptualized as real.
Now, look who needs explaining.LOL
