The following quote comes to me from the sno.
Here are some rules to think about
You have the tools to check them out.
A thing is not its given name.
There're no two things that are the same
Not even one thing stays the same.
If what I see isn't all there is
Then what I know may not be so.
If what you see is not my view
How can we know which view is true?
