"Relying on the face might be human nature - even babies prefer to look at attractive people. But, of course, judging someone based on the geometry of his features is, from a moral and legal standpoint, no better than judging him based on the color of his skin."

"Imagination tends to be truly useful if accompanied by the power of mental control - if the worlds in one's head can be purposefully manipulated and distinguished from the real one outside it."

"Imagination is Reality Lite - a useful substitute when the real pleasure is inaccessible, too risky, or too much work."

"It is clear that rituals and sacrifices can bring people together, and it may well be that a group that does such things has an advantage over one that does not. But it is not clear why a religion has to be involved. Why are gods, souls, an afterlife, miracles, divine creation of the universe, and so on brought in?"

"Some of the natural world is appealing, some of it is terrifying, and some of it grosses us out. Modern people don't want to be dropped naked into a swamp. We want to tour Yosemite with our water bottles and G. P. S. devices. The natural world is a source of happiness and fulfillment, but only when prescribed in the right doses."

"We are constituted so that simple acts of kindness, such as giving to charity or expressing gratitude, have a positive effect on our long-term moods. The key to the happy life, it seems, is the good life: a life with sustained relationships, challenging work, and connections to community."

"Even in the most peaceful communities, an appetite for violence shows up in dreams, fantasies, sports, play, literature, movies and television. And, so long as we don't transform into angels, violence and the threat of violence - as in punishment and deterrence - is needed to rein in our worst instincts."

"Our best hope for the future is not to get people to think of all humanity as family - that's impossible. It lies, instead, in an appreciation of the fact that, even if we don't empathize with distant strangers, their lives have the same value as the lives of those we love."
