Are we our brothers' keepers? Do we have an instinct for compassion? Or are we, as is often assumed, only on earth to serve our own survival and interests? In this thought-provoking book, the eminent biologist and acclaimed author of Our Inner Ape examines how empathy comes naturally to a great variety of animals, including humans. Written with a wealth of anecdotes, wry humor, and incisive intelligence, The Age of Empathy is essential reading for our embattled times.
