EXCERPT: For 2,000 years, there was an intuitive, elegant, compelling picture of how the world worked. It was called “the ladder of nature.” In the canonical version, God was at the top, followed by angels, who were followed by humans. Then came the animals, starting with noble wild beasts and descending to domestic animals and insects. Human animals followed the scheme, too. Women ranked lower than men, and children were beneath them. The ladder of nature was a scientific picture, but it was also a moral and political one. It was only natural that creatures higher up would have dominion over those lower down.

Darwin’s theory of evolution by natural selection delivered a serious blow to this conception. [...] Modern biological science has in principle rejected the ladder of nature. But the intuitive picture is still powerful. In particular, the idea that children and nonhuman animals are lesser beings has been surprisingly persistent. Even scientists often act as if children and animals are defective adult humans, defined by the abilities we have and they don’t. Neuroscientists, for example, sometimes compare brain-damaged adults to children and animals.

We always should have been suspicious of this picture, but now we have no excuse for continuing with it. [...] De Waal outlines both the exciting new results and the troubled history of the field. The study of animal minds was long divided between what are sometimes called “scoffers” and “boosters.” Scoffers refused to acknowledge that animals could think at all: Behaviorism—the idea that scientists shouldn’t talk about minds, only about stimuli and responses—stuck around in animal research long after it had been discredited in the rest of psychology. Boosters often relied on anecdotes and anthropomorphism instead of experiments. De Waal notes that there isn’t even a good general name for the new field of research. Animal cognition ignores the fact that humans are animals too. De Waal argues for evolutionary cognition instead. [...] De Waal explicitly rejects the idea that there is some hierarchy of cognitive abilities. Nevertheless, an implicit tension in his book shows just how seductive the ladder-of-nature view remains...
