Im not sure if its even 'intellegence' but rather a willingness to 'honestly allow' self-examination of one's beliefs. Common sense imo is a form of intellegence. There are all kinds of tenured professors who have intellegence but that intellect is diluted by ideology. Leftist ideology & rigid belief in Socialism trumps common sense and then they use their intellegence..not to question their belifs..but to 'validate' their beliefs. Anyway..great post...:)
