We cannot be secure by limiting our liberties, as some of our political leaders are demanding, but only by expanding themWe should take our example not from the military and political leaders shouting 'retaliate' and 'war' but from the doctors and nurses and firemen and policemen who have been saving lives in the midst of mayhem, whose first thoughts are not violence, but healing, and not vengeance, but compassion.

Is not nationalism - that devotion to a flag, an anthem, a boundary so fierce it engenders mass murder - one of the great evils of our time, along with racism, along with religious hatred? These ways of thinking - cultivated, nurtured, indoctrinated from childhood on - have been useful to those in power, and deadly for those out of power.

I see this as the central issue of our time: how to find a substitute for war in human ingenuity, imagination, courage, sacrifice, patience... War is not inevitable, however persistent it is, however long a history it has in human affairs. It does not come out of some instinctive human need. It is manufactured by political leaders, who then must make a tremendous effort--by enticement, by propaganda, by coercion--to mobilize a normally reluctant population to go to war.

I wonder how the foreign policies of the United States would look if we wiped out the national boundaries of the world, at least in our minds, and thought of all children everywhere as our own.

Why do we have to be a military superpower? Why can't we be a humanitarian superpower?

But I suppose the most revolutionary act one can engage in is... to tell the truth.

When I say history is a matter of life and death, I mean this: If you really don't know history, you are a victim of whatever the authorities tell you. You have no way of checking up on them. You have no way of deciding whether there is any truth in what they are saying.
