Ok, that seems right.
Try this.
In order to clearly delineate "truth" from "not truth", you must explicitly define what "can be true" and "what can never be true".
QUANTA versus QUALIA.
QUANTA = REAL-TRUE-FACTS which must be empirically verifiable and or logically necessary and demonstrable and indisputable and tautological and emotionally MEANINGLESS.
QUALIA = Qualitative, experiential, personal, OPINION, unverifiable and unfalsifiable PRIVATE, indemonstrable GNOSIS and most importantly, emotionally MEANINGFUL.
OPINION (QUALIA) can NEVER be considered "true" because OPINION holds no truth-value.
This severely limits the scope of potential REAL-TRUE-FACTS.
