Words are contracts for meaning in pursuit of reciprocity, or they are avoidance of contracts for meaning, in pursuit of irreciprocity: fraud. There is only one universal standard of weight and measure in speech, providing universal decidability in speech, and that is testimony in of the operational, empirical, internally consistent, coherent, complete, and surviving parsimony in competition with the alternatives.
Lke all humans I make mistakes. Unlike most humans I never err. This claim is not difficult: claim nothing is true you cannot testify to. Position all that you cannot testify to as a question rather than a statement. 😉 -cheers
