And if you look at all this academic work in the conferences and so on there's a constant theme that terrorism is extremely hard to define and we therefore have to have a deep thinking about it.

Why did the people think [Vietnam war] was fundamentally wrong and immoral? The guys who ran the polls, John E. Rielly, a professor at the University of Chicago, a liberal professor, he said what that means is that people thought too many Americans had being killed. Another possibility is they didn't like the fact that we were carrying out the worst crime since the Second World War. But that's so inconceivable that wasn't even offered as a possible reason.

Our concern is to help people counter the efforts of those who seek to "regiment the public mind every bit as much as an army regiments the bodies of its soldiers," so that the self-designated "responsible men" will be able to run the affairs of the world untroubled by the "bewildered herd" - the general public - who are to be marginalized and dispersed, directed to personal concerns, in a well-regulated "democracy."

Moral cowardice and intellectual corruption are the natural concomitants of unchallenged privilege.
