BTW moving key notions from the realm of somehow reality-testable to the realm of purely denotational and conventional was the way how the Party in "1984" ruled the minds of people. War is peace, freedom is slavery, etc. Also, such attacks on universal principles and the reality-testable are waged by taking the purely conventional and raising those up to the level of empirical fact and universal principle.
