“The Party told you to reject the evidence of your eyes and ears. It was their final, most essential command.”
― George Orwell, 1984
Dialectical Materialism; where dialectical means debate on theory vs. anti-theory where both are considered to be true, and materialism which does not mean possessions in the modern sense, but materialism means the material world where things can be seen, weighed and measured. Thus, under dialectical materialism a man can really be a woman. And the force of government can justifiably be used to enforce which of the dialectics is really true.
