Praise for the Work of Frans de Waal "The beauty of a book by Frans de Waal is that once you read it, you'll never look at your own species the same way again." -- Tamra Mendelson, Washington Post "Through colorful stories and riveting prose, de Waal firmly puts to rest the stubborn notion that humans alone in the animal kingdom experience a broad array of emotions.De Waal contributes immensely to an ethical sea change for animals." -- Barbara J. King, NPR "De Waal's eye-opening observations argue for better treatment and greater appreciation of animals, even as he ensures that you'll never look at them--or yourself--the same way again." -- People "A remarkable scientist. Drawing on a growing body of research including his own, de Waal shows that animals, from elephants and chimpanzees to the lowly invertebrates, are not only smarter than we thought, but also engaged in forms of thought we have only begun to understand." -- Edward O.

Wilson "This is a writer marshaling the evidence of his life, particularly his life as a scientist, to express a passionately held belief in the possibility of a more compassionate society." -- Meehan Crist, New Republic.
