those who control the system can assert any truth they desire. there are very few things in high level macroscopic reality which when expressed are entirely derivably true.  even the concept of a tactile object such as an apple has serious ambiguity about it when you really examine it closely, much less amorphous and ill defined concepts such as love or intelligence. we often fool ourselves into thinking language is a true representation of reality. <br>question everything, even the words of the question... and the answer.
