Peace is not the absence of conflict but the presence of creative alternatives for responding to conflict - alternatives to passive or aggressive responses, alternatives to violence.

Success is not assured, but America is resolute: this is the best chance for peace we are likely to see for some years to come - and we are acting to help Israelis and Palestinians seize this chance.

I just can't seem to write songs about peace and love. Yeah right, how do you get that?

Our science has become terrible, our research dangerous, our findings deadly. We physicists have to make peace with reality. Reality is not as strong as we are. We will ruin reality.

All my life I've taken photographs of people who are completely at peace being what they were in the situations I photographed them in.
