A friend of mine linked me to a video featuring Terrence Mckenna the other day...
Terrence encourages his followers to "erase" their learned behavior through drugs; but drugs strip a person of their ability to reason. When these people applaud, I can't help but cringe... Because intoxication persuades people by lowering the mental bar of judgement; while people gain judgement by learning. The intoxicated man commits adultery because his judgement is dismissed.
So... the easiest to persuade are those who's mental bars have been lowered. Terrence is eerily charismatic... in his own creepy way. Charlatan?
