Key passages
“Agreement with the truth-possibilities can be expressed by coordinating with them in the schema the mark “T” (true). Absence of this mark means disagreement.”
We can show that a proposition agrees with the possible truth values by placing a 'T' next to them in the truth table; if there is no 'T', it indicates disagreement.
