"An inspiring and engrossing new look at human goodness. Without sentimentality or glibness, and wearing his depth and erudition lightly, McCullough enlightens us on when and why we care for others."—Steven Pinker, author of Enlightenment Now
"This is a controversial book, but McCullough's arguments are smart, clear, and ultimately persuasive."—Paul Bloom, author of Against Empathy
"Enlightened by evocative anecdotes and well-explained theory, The Kindness of Strangers is as original as it is persuasive."—Richard Wrangham, author of The Goodness Paradox
"A fine achievement. McCullough expertly braids together the distinctive strands of evolutionary psychology, history, and philosophy to explore and explain a characteristic unique to our stage of development: kindness to strangers. An important book that looks at the whole of human history, and more, and thereby offers a valuable counterweight to the all-to-common view that everything is getting worse."— Peter Singer, author of The Life You Can Save and The Most Good You Can Do
}A deliciously provocative analysis of an entirely admirable human quality."
