What were they thinking?' we ask about our ancestors, but we know that, a century hence, our descendents will ask the same thing about us. Who knows what will strike them as strangest? The United States incarcerates 1 percent of its population and subjects many thousands of inmates to years of solitary confinement. In Saudi Arabia, women are forbidden to drive. There are countries today in which homosexuality is punishable by life in prison or by death. Then there's the sequestered reality of factory farming, in which hundreds of millions of mammals, and billions of birds, live a squalid brief existence. Or the toleration of extreme poverty, inside and outside the developed world. One day, people will find themselves thinking not just that an old practice was wrong and a new one right but that there was something shameful in the old ways. In the course of the transition, many will change what they do because they are shamed out of an old way of doing things. So it is perhaps not too much to hope that if we can find the proper place for honor now, we can make the world better.
