What does not agree with reality, does not exist.

We might have got there at last with Anthony, who now says "what does not agree with reality, does not exist".  I rather thought it was heading in that direction.  What a false statement asserts, does not agree with reality.  "Snow is black" says that snow is black. But snow being black does not agree with reality. Ergo, snow being black does not exist.  Ergo, "snow is black" does not state anything at all, for if it did, it would have to express a state of affairs that is not real, a non-enity, a nullity, a void.  Ergo, there are no false statements: all statements are true.

Nailed it at last.
