“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.”

“In short—to overstate the point only slightly—because people don’t really know why they do what they do, they give explanations of their own behavior that are about as reliable as anyone else’s, and in many circumstances actually less so.”

“Cultures are made of continuities and changes, and the identity of a society can survive through these changes. Societies without change aren't authentic; they're just dead”

“A value is like a fax machine: it’s not much use if you’re the only one who has one.”

“This is, of course, an easy Berlinian riposte. Start with some graceful hand waving about incommensurability; declare that nothing could reconcile these great goods; and (with a tip of trilby) commend liberal pluralism for living with the contradictions.”

“Who says history is stagnant? For a historian, facts do not change; it is the way we look at things, our interpretations, that are always changing. This is what makes history exciting - that we can always find something new in what is old.”

“Why do we so mindlessly abuse our planet, our only home? The answer to that lies in each of us. Therefore, we will strive to bring about understanding that we are--each one of us--responsible for more than just ourselves, our family, our football team, our country, or our own kind; that there is more to life than just these things. That each one of us must also bring the natural world back into its proper place in our lives, and realize that doing so is not some lofty ideal but a vital part of our personal survival.”
