Are We Smart Enough to Know How Smart Animals Are? by Frans de Waal. The short answer is--we're getting there. The gist of this fascinating book is that we've long been using the wrong measures for things like "consciousness," "self-awareness," and "intention," all once considered qualities possessed only by humans. But as the many experiments that primatologist de Waal recounts show, if you use the proper controls and keep an open mind, you'll find animals are far more "like" us than we give them credit--which changes everything.

What separates your mind from an animal's? Maybe you think it's your ability to design tools, your sense of self, or your grasp of past and future--all traits that have helped us define ourselves as the planet's preeminent species. But in recent decades, these claims have eroded, or even been disproven outright, by a revolution in the study of animal cognition.
