Geert asked:

What is reality??

============

I don't know. Looking out of the window I would believe the tree is a tree and the grass is the grass.
But I don't do physics. Probably no-one can say. What does reality mean? The only way we can take
things when not hallucinating, or what underlies the way things are?

I think it is our shared world and not the physicists' world. Realities are not all about particles but all of
the things mankind has in common. Apparently there are subjective, or personal, realities too.

Just because we have a word or concept, it doesn't mean we can say what it means.
