I keep encountering young people who, in spite of all the evidence of terrible things happening, also give hope. There are hundreds of thousands working for the good everywhere . . . To be hopeful in hard times is not just foolishly romantic. It is based on the fact that human history is a history not only of cruelty but also of compassion, sacrifice, courage, kindness. What we choose to emphasize in this complex history will determine our lives. If we see only the worst, it destroys our capacity to do something. If we remember those times and places—and there are so many—where people have behaved magnificently, this gives us the energy to act, and at least the possibility of sending this spinning top of a world in a different direction. The future is an infinite succession of presents, and to live now as we think human beings should live, in defiance of all that is bad around us, is itself a marvelous victory.
