"The loss of seriousness seems to me to be, in effect, a loss of hope. I think that the thing that made people rise to real ambition, real gravity was the sense of posterity, for example - a word that I can remember hearing quite often when I was a child and I never hear anymore. People actually wanted to make the world good for people in generations that they would never see. It makes people think in very large terms to try to liberate women, for example, or to try to eliminate slavery."
