"Nothing - Undefined/Abstract" = is a fiction, does not exist, cannot be pondered because logic requires definitionOriginally posted by Mentat
And yet I haven't been answered...you didn't say anything that it was equivalent to.
You know, I think another problem is that you've equated being about to refer to something but not doing so with referring to "nothing". This is also not the case, but is much closer to correct. You did indeed refer to nothing (=you didn't refer to anything) but you are no closer to finding what the word "nothing" refers to then you were to begin with. " " isn't nothing, it's two quotation marks around and empty space (the empty space itself being something).
"Nothing - Defined/Logical" = The Empty Set or Ø
It is purely semantical. "Nothing" has two connotations. You seem willing to only accept the first connotation.
