Professor Levy: [voiceover] We are all faced throughout our lives with agonizing decisions. Moral choices. Some are on a grand scale. Most of these choices are on lesser points. But! We define ourselves by the choices we have made. We are in fact the sum total of our choices. Events unfold so unpredictably, so unfairly, human happiness does not seem to have been included, in the design of creation. It is only we, with our capacity to love, that give meaning to the indifferent universe. And yet, most human beings seem to have the ability to keep trying, and even to find joy from simple things like their family, their work, and from the hope that future generations might understand more.
