Every night I get many letters, and after every talk I get many questions from people who say, "I want to change things. What can I do?" I never hear these questions from peasants in southern Colombia or Kurds in southeastern Turkey under miserable repression or anybody who is suffering. They don't ask what they can do; they tell you what they're doing.

Science talks about very simple things, and asks hard questions about them. As soon as things become too complex, science can't deal with them... But it's a complicated matter: Science studies what's at the edge of understanding, and what's at the edge of understanding is usually fairly simple. And it rarely reaches human affairs. Human affairs are way too complicated.

Unlimited economic growth has the marvelous quality of stilling discontent while maintaining privilege, a fact that has not gone unnoticed among liberal economists.

Our ignorance can be divided into problems and mysteries. When we face a problem, we may not know its solution, but we have insight, increasing knowledge, and an inkling of what we are looking for. When we face a mystery, however, we can only stare in wonder and bewilderment, not knowing what an explanation would even look like.

During the terrorist regime in Haiti in the 1990s, the CIA, under the administration of Bill Clinton, was reporting to Congress that oil shipments had been blocked from entering Haiti. That was just a lie. I was there. You could see the oil terminals being built and the ships coming in.

There are very few people who are going to look into the mirror and say, 'That person I see is a savage monster;' instead, they make up some construction that justifies what they do.

One should be cautious about "general conceptions." I think a strong case can be made that activism today is as high as ever, perhaps more so, and is also taking new and significant forms. There has never been anything like the international solidarity movements that began to take shape in the 1980s, right in the mainstream, or the global justice movements that have become a very powerful force in later years. It's true that the society is highly atomized, which does induce a sense of hopelessness often - quite mistakenly I think.
