To me, activism requires you to try very hard to open your eyes to the world as it is. See as much as you can, knowing that whatever you see is going to be partial. That you possess a partial consciousness in an infinite and expanding universe.

The only path to the final defeat of imperialism and the building of socialism is revolutionary war.

The president of the University said that night, congratulations to you the students, you've won a great victory, now the war will end. And I'm certain that he believed it that night and I believed it and we went away happy. Four days later, Martin Luther King was assassinated. Two months after that, Kennedy was assassinated. Two months after that, Henry Kissinger emerged from the swamp he was living in at Harvard with a plan to expand the war.

You cannot live a political life, you cannot live a moral life if you're not willing to open your eyes and see the world more clearly. See some of the injustice that's going on. Try to make yourself aware of what's happening in the world. And when you are aware, you have a responsibility to act.

What were the politics of my family? They were mainstream moderate politics.

The responsibility for the risks we posed to others in some of our most extreme actions in those underground years never leaves my thoughts for long. The antiwar movement in all its commitment, all its sacrifice and determination, could not stop the violence unleashed against Vietnam. And therein lies cause for real regret.

All that means to me is that people who have a vision of a better world have a responsibility to open their eyes, to pay attention, to act on what the moment demands, and to be humble about that action.
