I have actually tried it. I drew one square Venn diagram, one Venn

marker. This method of visualization worked well, and I was very
pleased with my picture. But then i realized there was trouble. I
could not find the intersection of the square Venn and the circle
Venn. I stared at it for several hours and I still could not find it.
I could not visualize the intersection being inside the green zone, it
(the intersection just was not there.

So you don't understand the empty set?

The empty set is like the word "nothing." It is a grammatical noun but
it actually does not denote anything. It is just a placeholder. You
should not mistake nothing for something. See Rudolf Carnap:
"Elimination of Metaphysics Through the Logical Analysis of Language."
